Maria is saving money to buy a bike. She has $42 and is going to save an additional $ 7 each week. The bike costs $133. In how many
weeks will she have enough money to buy the bike?
Answer:
Maria will have enough money to buy the bike in 13 weeks.
Step-by-step explanation:
w = weeks
42 + 7w = 133
take away 42 frim each side
7w = 91
divide each side by 7
w = 13
The length of a rectangle is 5 inches more than its width. The area of the rectangle
is 150 centimeters. Find the dimensions of the rectangle.
it's good to write it out
length = 5 + width
area = 150
width = x
length = 5 + x
area = length * width
so
(5 + x) (x) = 150
5x + x^2 = 150
x^2 + 5x - 150 = 0
following you have to guess what 2 numbers when multiplied male 150 and when added make 5
and they are 15 and 10
(x +15) (x-10)
x = -15
x = 10
so the dimensions are
length = 15
and
width = 10

Question 5 (1 point) 5 The Cool Shirts company prints personalized designs on T-shirts. The cost y for x shirts with the same design is shown in the table below. y 10 $105 20 $185 30 $265 4:0 $345 Which equation represents the relationship between x and yo! A y = 10x - 55 By = 80x + 105 C y = 8x + 25 D y = 25x + 8 a А B od
Answer:
y = 8x + 25
Step-by-step explanation:
Using the coordinates (10, 105) and (20, 185)
The standard linear equation is expressed as y = mx+c
m is the slope
c is the intercept
m = 185 - 105/20-10
m = 80/10
m = 8
Get the y-intercept
Since y = mx+c
105 = 8(10) + c
105 = 80 + c
c = 105 - 80
c = 25
Get the required equation
Recall that y = mx+c
y = 8x + 25
Hence the required equation is y = 8x + 25

HELP
Answer:
B ; C ; D
Step-by-step explanation:
Number of faces on a number cube = 6
Sample space = (1, 2, 3, 4, 5, 6)
P(1 then 0)
P(1) = 1/6 ; P(0) = 0
P(1 then 0) = 1/6 * 0 = 0
P(even number then odd number) :
P(even number) = 3/6 = 1/2
P(odd) = 3/6 = 1/2
P(even number then odd number) = 1/2 * 1/2 = 1/4
P(6 then 2) :
P(6) = 1/6 ; P(2) = 1/6 = 1/2
P(6 then 2) = 1/6 * 1/6 = 1/36
P(even number then 5) :
P(even) = 3/6 = 1/2
P(5) = 1/6
P(even number then 5) = 1/2 * 1/6 = 1/12
P(odd number then 2) :
P(odd) = 3/6 = 1/2
P(2) = 1/6
P(odd number then 2) = 1/2 * 1/6 = 1/12

Solve each system of linear equations by using substitution method.
x - y = -2
2x + y =5
100 POINTS PLS ANSWER
Answer:
x = 1, y = 3
Step-by-step explanation:
Given:
x - y = -2
2x + y = 5
First, add y on both sides for the first equation.
x = y - 2
Then, plug in x into the second equation.
2(y -2) + y = 5
2y - 4 + y = 5
3y = 9
y = 3.
Next, now that you've found y, plug it into either the first or second equation to solve for x. I'll be using the second equation.
2x + 3 = 5
2x = 2
x = 1.
Ans: x = 1, y = 3

Answer:
-3x^2+16x+64
Step-by-step explanation:
First, you need to find the area of both areas (the total area and the area of the unshaded part). Let's find the total area.
(x+8)(x+8)=x^2+16x+64
The total area is x^2+16x+64
(2x)(2x)=4x^2
The area of the unshaded part is 4x^2
Now we have to subtract to find the area of the shaded part.
x^2+16x+64-4x^2
-3x^2+16x+64
That is the answer
Hope this helped!! :D
When Camden runs the 400 meter dash, his finishing times are normally distributed with a mean of 65 seconds and a standard deviation of 1.5 seconds. Using the empirical rule, determine the interval of times that represents the middle 68% of his finishing times in the 400 meter race.
Answer:
63.5, 66.5
Step-by-step explanation:
Approximately 68% of Camden's finishing times fall within the interval from 63.5 seconds to 66.5 seconds.
What is the empirical rule?The empirical rule states that for a normal distribution, approximately 68% of the data lies within one standard deviation of the mean, approximately 95% of the data lies within two standard deviations of the mean, and approximately 99.7% of the data lies within three standard deviations of the mean.
Since we want to find the interval that represents the middle 68% of Camden's finishing times, we need to find the range of times that are one standard deviation above and below the mean.
The mean of Camden's finishing times is 65 seconds, and the standard deviation is 1.5 seconds, so the interval that represents the middle 68% of his finishing times is:
[65 - 1.5, 65 + 1.5] = [63.5, 66.5] seconds
This means that approximately 68% of Camden's finishing times fall within the interval from 63.5 seconds to 66.5 seconds.

Answer:
I believe it is D
Step-by-step explanation:
We can first multiply the 2 and 4 together to get 8.
Wow we already eliminated A.
When you have negative powers, you can just replace it with their inverse and turn the power positive.
For example, 2 to the power of -3 (2 ^ -3) can be replaced by 1/2 to the power of 3 (1/2^-3).
So we now have 8 (x^4 / yx^2
We can then just subtract the x's power of 2, because when dividing exponents with the same variable or base, we can just subtract them.
For example, x^5 divided by x ^ 2 has the same base/ variable of x, and you can subtract the 5 by 2 to get x^3.
So we have 8 ( x^2y)
So 8x^2 y

Drew has two cats. One cat weighs 17 pounds, and the other one weighs 1212 pounds. Audrey’s dog weighs 33 pounds.
What is the difference in ounces between Audrey’s dog and the combined weights of Drew’s cats?
Enter your answer in the box.
Answer:
48 ounces
Step-by-step explanation:
Answer:
64 ounces.
Step-by-step explanation:
combined weigh = weight of cat 1 + weight of cat 2
combined weigh = 17 + 12 = 29 pounds
The difference in weight of the Dog's weigh by the combined cat's weigh is the subtraction between the two, so we have:
Difference in weigh = 33 - 29 = 4 pounds
We now have to convert it to ounces, since 1 pound contains 16 ounces we can multiply the value of the weigh in pounds by 16 to obtain the final value:
Difference in weigh = (4 pounds)* 16 = 64 ounces

Help, so You pick a card at random. Without putting the first card back, you pick a second card at random. There are 3 cards, a 5 a 6 and a 7 What is the probability of picking a 5 and then picking a 6?
Given:
There are 3 cards, a 5 a 6 and a 7.
You pick a card at random. Without putting the first card back, you pick a second card at random.
To find:
The probability of picking a 5 and then picking a 6.
Solution:
We have,
Total number of cards = 3
Number of card of 5 = 1
So, probability of getting a card of 5 is:
[tex]P(5)=\dfrac{\text{Number of card of 5}}{\text{Total number of cards}}[/tex]
[tex]P(5)=\dfrac{1}{3}[/tex]
After this selection, the remaining number of cards is 2. So, probability of getting a card of 6 in second draw is:
[tex]P(6)=\dfrac{\text{Number of card of 6}}{\text{Total number of remaining cards}}[/tex]
[tex]P(6)=\dfrac{1}{2}[/tex]
Now, the probability of picking a 5 and then picking a 6 is
[tex]P(\text{5 then 6})=P(5)\times P(6)[/tex]
[tex]P(\text{5 then 6})=\dfrac{1}{3}\times \dfrac{1}{2}[/tex]
[tex]P(\text{5 then 6})=\dfrac{1}{6}[/tex]
Therefore, the probability of picking a 5 and then picking a 6 is [tex]\dfrac{1}{6}[/tex].

Using the Exxon data as an example pretend Pennys Pickles divide their company into 10,000 shares of stock. If you buy 200 of these shares what percent of Penny's Picklesdo you own
Penny's Pickles divide their company into 10,000 shares of stock. If you buy 200 of these shares then you will have [tex]2\[/tex] percent of Penny's Pickles.
What is percentage?Percentage a is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, [tex]\%[/tex].
Percentage [tex]=\frac{ You\ owned}{Total \ share} * 100[/tex]
We have,
Total shares of Penny's Pickles [tex]=10,000[/tex]
You owned shares [tex]= 200[/tex]
So,
Using above formula,
Percentage [tex]=\frac{ You\ owned}{Total \ share} * 100[/tex]
Percentage of shares I owned [tex]=\frac{200}{10000} * 100[/tex]
[tex]= 2 \%[/tex]
So, the shares you owned are [tex]2\ \%[/tex] of total share of the Penny's Pickles.
Hence, we can say that Penny's Pickles divide their company into 10,000 shares of stock. If you buy 200 of these shares then you will have [tex]2\[/tex] percent of Penny's Pickles.
