Brianna bought two pounds of strawberries for 4.80 What is the price of dollars ounce per strawberries 1 pound = 16 ounces
Answer:
There are 16 ounces in 1 pound, so Brianna bought 2 x 16 = <<2*16=32>>32 ounces of strawberries.
The total cost was 4.80 dollars for 32 ounces.
To find the price per ounce, we divide the total cost by the number of ounces:
4.80 / 32 = 0.15
Therefore, the price of dollars per ounce for strawberries is $0.15.

A multivitamin constaions. 17g of vitamin C. How much vitamin c does 60 tablets contain? answer in milligrams
60 tablets of the multivitamin, with 17g (17,000mg) of vitamin C per tablet, contains 1,020,000mg of vitamin C in total.
If one tablet of the multivitamin contains 17g of vitamin C, then 60 tablets would contain 60 times that amount:
60 tablets x 17g of vitamin C per tablet = 1020g of vitamin C
However, it is more common to express vitamin C (and other nutrients) in milligrams (mg) rather than grams (g). To convert from grams to milligrams, we can multiply by 1000:
1020g of vitamin C x 1000 mg/g = 1,020,000 mg of vitamin C
Therefore, 60 tablets of the multivitamin contain 1,020,000 mg of vitamin C.
Just to clarify, in the answer above, I made a mistake in the units. 17g is actually 17,000mg, not 17mg. So the correct calculation is:
If one tablet of the multivitamin contains 17,000mg of vitamin C, then 60 tablets would contain 60 times that amount:
60 tablets x 17,000mg of vitamin C per tablet = 1,020,000mg of vitamin C
Therefore, 60 tablets of the multivitamin contain 1,020,000mg of vitamin C.

Each girl will receive the ratio of Girl 1: R2000, Girl 2: R3000 Girl 3: R7000
To find out how much each girl will get, we need to first add up the ratios:
2 + 3 + 7 = 12
Then, we can divide the total amount of money by the total ratio:
12000 ÷ 12 = 1000
This means that each "part" of the ratio is worth R1000.
To calculate how much each girl will get, we need to multiply their respective ratios by R1000:
Girl 1: 2 parts x R1000/part = R2000

Answer:
(x-6)(x-2)
Step-by-step explanation:
To factor, we use the quadratic formula, which gives us the roots of the equation. In an equation as ax²+ bx + c, we can use (-b±√(b^2-4ac))/2a. Since we have x² - 8x +12, a will be 1, b will be -8, and c will be 12.
(-(-8)±√((-8)²-4(1)(12))/2(1)
(8±√(64-48)/2
(8±√16)/2
(8±4)/2
We now have two cases: (8+4)/2 and (8-4)/2. We can solve these:
(8+4)/2 = 12/2 = 6
(8-4)/2 = 4/2 = 2
Since we have to factor this, we have to write it in the form of
(x-z)(x-y)
for z, we have 6, and for y, we have 2
(x-6)(x-2) is our final answer.

Find the area of the triangle with vertices (10, 1), (7, 11), and (7, 1).
The area of the triangle is 15 square units.
What is area of triangle?The area of a triangle is a measure of the size of the region enclosed by the three sides of the triangle. The formula for finding the area of a triangle depends on the length of its base and height, which are usually denoted by "b" and "h", respectively.
We can find the area of the triangle with vertices (10, 1), (7, 11), and (7, 1) by using the formula for the area of a triangle:
area = (1/2) * base * height
where the base is the distance between the two points with the same y-coordinate, and the height is the distance from the third point to the line that contains the base.
The base is a vertical line segment with length 11 - 1 = 10, since the two points (7, 11) and (7, 1) have the same y-coordinate.
The height is the distance from the point (10, 1) to the line that contains the base. Since the line is vertical and passes through the point (7, 1), the distance is simply the difference between the x-coordinates of the two points: 10 - 7 = 3.
Substituting these values into the formula, we get:
area = (1/2) * 10 * 3
= 15
Therefore, the area of the triangle is 15 square units.

Two bags contain white and yellow balls. Bag 1 contains two white balls and four yellow balls. Bag 2 contains four white balls and five yellow balls. A ball is drawn at random from each container. What is the probability that both balls are white?
A. 1/9
B. 1/6
C. 4/27
D. 10/201
Answer:
C. 4/27
Step-by-step explanation:
Let's use the multiplication rule of probability to calculate the probability that both balls drawn are white:
P(white ball from Bag 1) = 2/6 = 1/3
P(white ball from Bag 2) = 4/9
Therefore, the probability of drawing a white ball from each bag is:
P(white from Bag 1 and white from Bag 2) = P(white from Bag 1) * P(white from Bag 2)
= (1/3) * (4/9)
= 4/27
So, the answer is C. The probability that both balls are white is 4/27.

5) (8 pts) A company’s design of 45-ohm resistors is believed to be manufactured with a standard deviation of 0.12 Ω. To evaluate this, a sample of 15 resistors was collected and the standard deviation of the resistance of these 15 resistors was 0.194 Ω. a) (6 pts) Calculate a 95% two-sided confidence interval for standard deviation of resistance, σ. b) (2 pts) Based on your answer to part (a), is it reasonable to believe that the standard deviation of all resistors produced is 0.12 Ω? Explain your answer using information from part (a).
The true value of the standard deviation may be in the interval of (0.12, 0.3757), it may or may not be 0.12 Ω.
Calculation of a 95% two-sided confidence interval for standard deviation of resistance, σ95% two-sided confidence interval for standard deviation of resistance is given by:\[\left(\sqrt{\frac{\left(n-1\right)s^2}{\chi_{0.025,n-1}^2}},\sqrt{\frac{\left(n-1\right)s^2}{\chi_{0.975,n-1}^2}}\right)\]where s = 0.194 Ω, n = 15, and Χ² distribution with df = 14 at α = 0.05/2 = 0.025/0.975The range of the 95% two-sided confidence interval for the standard deviation of resistance is given as follows:95% two-sided confidence interval for standard deviation of resistance = (0.12, 0.3757)Hence, the 95% two-sided confidence interval for the standard deviation of resistance is given as (0.12, 0.3757).b) Explanation:The standard deviation of the resistance is believed to be 0.12 Ω. From the 95% confidence interval obtained in part (a), 0.12 Ω is not within the 95% confidence interval. This means it is not reasonable to believe that the standard deviation of all resistors produced is 0.12 Ω. Since the true value of the standard deviation may be in the interval of (0.12, 0.3757), it may or may not be 0.12 Ω.

can someone help me solve the area of this composite figure please
Therefore, the area of the composite figure is 65 square centimeters. Therefore, the area of the composite figure is approximately 150.8 square centimeters.
What is area?In mathematics, the area is the measure of the size of a two-dimensional surface or shape. It is the amount of space inside the boundary of a flat object, such as a triangle, rectangle, circle, or any other polygon. The standard unit of measurement for area is square units, such as square meters (m²), square centimeters (cm²), or square feet (ft²). To calculate the area of a shape, we usually use a formula that depends on the shape's geometry and dimensions, such as its length, width, radius, or height. Area has many applications in everyday life, such as calculating the size of a room, the amount of paint needed to cover a wall, or the area of land required to build a house or grow crops. In mathematics and science, area is also used to solve problems in geometry, physics, engineering, and other fields.
Here,
1. Combination of Square and Rectangle
To find the area of this composite figure, we need to break it down into simpler shapes and add up their areas. The figure consists of a square with sides of 5 cm, a rectangle with sides of 4 cm and 9 cm, and a square with sides of 2 cm.
The area of the square with sides of 5 cm is:
A1 = (side)²
= (5 cm)²
= 25 cm²
The area of the rectangle with sides of 4 cm and 9 cm is:
A2 = length x width
= (9 cm) x (4 cm)
= 36 cm²
The area of the square with sides of 2 cm is:
A3 = (side)²
= (2 cm)²
= 4 cm²
To find the total area of the composite figure, we add up the areas of these three shapes:
A = A1 + A2 + A3
A = 25 cm² + 36 cm² + 4 cm²

2000 people lived in a village in the year 1999. By the year 2004 ,the male were increased by 10% and the women decreased by 6%. But the total population remain unchanged. How many males lived in the village by 1999?
The number of males in the village in 1999 was 1200, given that the male to female ratio was 3:5 and the total population was 2000.
Let's assume that in the year 1999, there were M males and W females living in the village, so the total population would be P = M + W = 2000.
Then, in the year 2004, the male population increased by 10%, so the number of males became 1.1M, and the female population decreased by 6%, so the number of females became 0.94W.
The total population remained unchanged, so we have:
1.1M + 0.94W = P = 2000
We also know that P = M + W, so we can substitute this into the above equation:
1.1M + 0.94W = M + W
0.1M = 0.06W
M/W = 3/5
So the ratio of males to females in the village in 1999 was 3:5. Therefore, we can write:
M + W = 2000
3/5 (M + W) = 3/5 (2000)
M = 1200
Therefore, there were 1200 males living in the village in the year 1999.
We can check that this answer is consistent with the information given in the problem. In 1999, there were 2000 people in the village, and the ratio of males to females was 3:5. This means that the number of males is 3/8 of the total population, and the number of females is 5/8 of the total population:
Number of males = 3/8 x 2000 = 750
Number of females = 5/8 x 2000 = 1250
Now let's apply the changes that occurred between 1999 and 2004. The male population increased by 10%, so the new number of males is:
1.1 x 750 = 825
The female population decreased by 6%, so the new number of females is:
0.94 x 1250 = 1175
The total population is:
825 + 1175 = 2000
So the total population remained unchanged, as required by the problem statement. Therefore, our answer of 1200 males in 1999 is consistent with the information given in the problem.

Write a quadratic function for the area of the figure. Then, find the area for the given value of x.

Answer:
Area = π*r^2
Area = 113.1 units^2
Step-by-step explanation:
The figure drawn is a circle. The ancient Greeks devised an approximation of the area of circles by dividing the circle into a series of small triangles with their peaks at the center of the circle and their bases are formed by the curve of the circle. Although this means there is an error because the circumference is not a straight line, they made the triangles small enough so that the error would be minimized. They found that the area of the circle was related to it's radius by the expression: Area = π*r^2.
Without retracing their steps, let's simply use the formula that is now the accepted measure of the area of a circle. Pi (π) is 3.14 to 3 decimal places. Far more accurate values are known, but 3.14 offers reasonable accuracy, assuming this is not intended for space flight.
Area = π*r^2
Area = 3.34*(6)^2

Therefore , the solution of the given problem of percentage comes out to be down payment is 32% of the overall cost of the vehicle.
What is percentage, exactly?In statistics, a% is a number or value that is expressed as a fraction of 100. The terms "pct.," "pct.," but also "pc" are also infrequently used. Nevertheless, the symbol "%" is frequently used to indicate it. The percentage sum is flat; there are no dimensions. Since the numerator of a percentage is always 100, percentages truly constitute integers. Either the percent symbol (%) or the word "percent" must come before a number to denote that it is a percentage.
Here,
Levi Hempke wishes to borrow a maximum of $14,280 to finance a $21,000 vehicle. Consequently, he intends to put down:
=> $21,000 - $14,280 = $6,720
We must divide his down payment by the total cost of the car, multiply by 100 to convert to a percentage, and
then determine the percentage of the total cost of the car that he should put down:
=> ($6,720 ÷ $21,000) × 100 = 32%
Levi's down payment should therefore equal 32% of the overall cost of the vehicle.

The multiplication problem that matches the model is: 5 * 1/2
How to identify the multiplication model?A representation is a way of showing multiplication. A model for multiplication is slightly more sophisticated and it is comprised of several related representations that all have the same structure. There are two models for multiplication namely repeated addition and arrays.
From the attached file, we see that there are 5 images. Now, each image depicts a triangle that is shaded in half.
Thus, it means that each triangle represents the fraction 1/2.
Thus, the model will be expressed as a multiplication model as;
