A dog run has an area of at least 150 square feet. The length of the run has to be 12 feet. What us the width of the run?​

Answers

Answer:

The width is 12.5

Step-by-step explanation:

so you would do 150 divided by 12 which would give you 12.5 so the width has to be 12.5 because length times width = area and 12.5 time 12 = 150

Hope this helped :3  o(* ̄▽ ̄*)ブ

Answer:

12.5 ft

Step-by-step explanation:

Area of a rectangle of length L and width W:  A = L * W

Then 150 ft^2 = (12 ft)(width), and so:

(width) = (150 ft^2) / (12 ft) = 12.5 ft

14 adults and 20 children attended a piano recital. If two people are selected to receive door prizes at the recital, what is the probability that both will be children? Write your answer as a fraction and a decimal rounded to the nearest hundredth.

Answers

Answer: 0.34

Step-by-step explanation:

From the question, 14 adults and 20 children attended a piano recital. This means that there are 14 + 20 = 34 people who attended the paint recital.

If two people are selected to receive door prizes at the recital, the probability of selecting the first child will be 20/34 while the second child will be 19/33. To get the probability of both being children, we have to multiply the fractions

= 20/34 × 19/33

= 380/1122

= 0.34

What is the volume of the right cone below?

Answers

Answer:

The answer is A.

Step-by-step explanation:

You have to use the formula of volume of cone,

[tex]v = \frac{1}{3} \times \pi \times {r}^{2} \times h[/tex]

Given that the diameter of cone is 10 units so the radius is 5. Then substitute the followung values into the formula :

Let r = 5 units,

Let h = 45 units,

[tex]v = \frac{1}{3} \times \pi \times {5}^{2} \times 45[/tex]

[tex]v = \frac{1}{3} \times \pi \times 1125[/tex]

[tex]v = 375\pi \: \: {units}^{3} [/tex]

Answer:

[tex]375\pi \: \: units ^{3} [/tex]

Answer A is correct.

Step-by-step explanation:

[tex]v = \pi {r}^{2} \frac{h}{3} \\ =\pi \times 5 \times 5 \times \frac{45}{3} \\ = \pi \times 25 \times 15 \\ = 375\pi \: \: units ^{3} [/tex]

37.5(3.8-x)+90x=300 please help me

Answers

Answer:

I’m just copying his answer which is 3

Step-by-step explanation:

at least I tried

Answer: 3

Step-by-step explanation:

37.5 (3.8-x) + 90x = 300

First, you have to simplify, by using the Distributive Property.

142.5 - 37.5x + 90x = 300

Now, add the like terms

142.5+ 52.5x = 300

Now, isolate the variable, meaning the variable has to be on one side on its own. You would have to subtract 142.5 and move it to the other side

52.5x = 300 - 142.5

52.5x = 157.5

Then, you divide!

[tex]\frac{52.5x}{52.5x}[/tex] = [tex]\frac{157.5}{52.5x}[/tex]

Answers

Answer:

For X they would have to divide the number from the first given chart for average household of the people that are ages 40 or under, which is 23, by the total internet, which is now 77.

Therefore, X = 23/77 = 0.2987, which would round to 0.30
