A rectangle has an area of 15 square millimeters. The width of the rectangle is 3 millimeters.

Answer:

x = -1

Step-by-step explanation:

Since a triangle's angles all add up to 180 based on this formula: 180(n-2) (n being the # of sides of the shape you're solving for, and the total being the interior), we can set up this equation:

46 + (x+62) + 73 = 180

Now, we can solve for x:

x = 180-73-62-46

x = -1

The statement that answers the linear model possibility is NO

From the question, we have the following parameters that can be used in our computation:

Initial = 100

Year 1 = 110

year 2 = 121

year 3 = 133.10

The savings account balance is increasing at an inconsistently increasing rate, which is not linear.

The savings account starts with $100, and increases by $10 in the first year, by $11 in the second year, and by $12.10 in the third year.

This is an example of exponential growth, which cannot be modeled by a single linear equation.

The vector joining the ship to the rock is t= 5i+5 j

A vector is a quantity or phenomenon that has two independent properties: magnitude and direction, a quantity that has both magnitude and direction but not position.

The direction is 0.9505 radians east of north.

The position vector of the ship: r= 1i+0j

Step-by-step explanation:

The probability that the mean loss from f-i-re is larger than $300 for an S-R-S of 1000 home owners is 0.3085.

This problem can be solved using the Central Limit Theorem, which states that the sampling distribution of the mean of any independent, random variable will be normal or nearly normal if the sample size is large enough (typically if n > 30).

Since the population is strongly right-skewed and the sample size is large (n = 1000), we can assume that the sampling distribution of the mean loss from fi-re will be approximately normal.

The mean of the sampling distribution is equal to the population mean, and a standard deviation equal to the population standard deviation divided by the square root of the sample size. In this case, we have:

Populatio mean (μ) = $250

Population standard deviation (σ) = $5000

Sample size (n) = 1000

Sample mean = $300

Probability of sample mean > $300 = ?

Now, standard deviation of sample mean = σ / sqrt(n) = $5000 / sqrt(1000) = $158.11

Now, we need to standardize the sample mean using the z-score formula:

z = (sample mean- population mean) / (σ / sqrt(n)) = (300 - 250) / 158.11 = 0.316

Using a standard normal distribution table or calculator, we can find the probability of a z-score greater than 0.316 to be approximately 0.3765 or about 37.65%.

Three lots with parallel side boundaries extend from the avenue to the boulevard.

x + y + z = 140 meters

According to the proportion theorem,

Solving for x, using cross multiplication:

Similarly,

x/40 = z/35

solving for z by cross multiplication,

z = 35x/40

z = 7x/8

Now, the third proportions,

y/30 = z/35

Solving for y,

y = 30z/35

y = 6z/7

x + y + z = 140

4y/3 + 6z/7 +  7x/8 = 140

(224y + 144z + 147x)/168 = 140

224y + 144z + 147x = 23520

Substituting z = 7x/8,

224y + (144 × 7x/8) + 147x = 23520

224y + 126x + 147x = 23520

224y + 273x = 23520

Now,

Substitute y = 3x/4

(224×3x/4) + 273x = 23520

168x + 273x = 23520

441x = 23520

x = 53.33

A cylinder can be measured in two separate ways: volume and area. As area gauges an object's two-dimensional surface, volume gauges how much space an object takes up.

If the cylinder's height and base area are known, the cylinder's volume may be determined by multiplying the base area by the cylinder's height. By dividing the base's circumference by its height, one may get the cylinder's area.

Given,

Volume of basket = 15 cubic feet

h = 1.5 ft

V = πr²h

15 = πr² (1.5)

πr² = 15/1.5

πr² = 10 ft²

Area of base of the basket = 10 ft²

15 = πr² (1.5)

r = √15/π(1.5)

We may obtain radius of basket = 1.78 by simplifying the numbers.

The hypotenuse of the right triangle, which also contains the cone height as one of its legs, is formed by the radius (18 m) and slant height. You may find out the height (h) using the Pythagorean theorem.

The Pythagorean Theorem states that the squares on the hypotenuse (the side across from the right angle) of a right triangle, or, in standard algebraic notation, a2 + b2, are equal to the squares on the legs.

The two different possible values for height h and radius r for the cones are height = 3 inches when radius = 3 inches and height = 4.5 inches when radius = 2 inches.

The volume of a cone is given by the formula [tex]V = (1/3)\pi r^2 h[/tex].

We can use this formula to find the values of h and r that will give us a cone with a volume of 9π cubic inches.

We have a volume of the cone -

(1/3)π[tex]r^2[/tex]h = 9π

solving for h, we get,

h = (3/[tex]r^2[/tex]) * 9

Now we have a formula for h in terms of r. We can substitute different values for r and see what values of h we get. Let's consider two possibilities:

                   h = (3/[tex]3^2[/tex]) * 9 = 3 inches

                   h = (3/[tex]2^2[/tex]) * 9 = 4.5 inches

Answer:

To estimate the total weight of the pet food Adam buys, we can use benchmark fractions to compare the weight of the dog food (7/8 pound) and the weight of the cat food (1 3/4 pounds) to a benchmark fraction that we are familiar with.

We know that 1 whole pound is equal to 16 ounces. So, we can use this as a benchmark to estimate the weight of the dog food and cat food.

First, we'll convert 7/8 pound to ounces. 7/8 pound is equal to 7/8 * 16 = 14 ounces

Next, we'll convert 1 3/4 pound to ounces. 1 3/4 pound is equal to 1 * 16 + 3/4 * 16 = 16 + 12 = 28 ounces.

Now we can add the weight of the dog food and the cat food to get the total weight of the pet food Adam buys.

14 ounces + 28 ounces = 42 ounces

So, the total weight of the pet food Adam buys is approximately 42 ounces, which is roughly 2.6 pounds.

The estimate was made with benchmark fractions, which allows us to make a rough estimation of the weight of the pet food, but it's not as precise as the exact weight in pound or ounces.

The slope-intercept form of an equation is - y = mx + b

To find the slope m use the formula -

XW = YZ = 2 × 4

XW = YZ = 8 inches

This means, the width of rectangle WXYZ is  8 inches

We know that the area of the reactngle is given by the formula,

A = length × width

here, A = 115.5 in.² and width = 8  in.

115.5 = length × 8

length = 115.5 / 8

length = 14.44 in.

So, XY = WZ =  14.44 in.
