Answer:

a) 5 meters b) About 15.71 meters

Step-by-step explanation:

a) Since the area of the square is 25m^2, we can say that the length and width of the square is 5m.

The circle that is inside the square will have the same length diameter as the length of the square.

Since the length of the square is 5m, the line in the middle of the circle will also be 5m.

b) Circumference = 2πr

Since we know the diameter of the circle is 5, we can divide it in half to get the radius.

5/2 = 2.5

2π(2.5) is about 15.70796326

The circumference of the circle will be about 15.71 meters

Semmy [17]

Answer:

The price of elasticity of demand is 2.59

Step-by-step explanation:

* Lets explain how to solve the problem

- During the past year the price of a laptop computer fell from

$2950 to $2450

- During the same time period consumer sales increased from

430000 to 619000 laptops

- We need to find the price of elasticity of demand

- The rule of price elasticity is:

price elasticity = percentage of change in the quantity ÷

percentage of change in price

* Lets calculate the percentage of change in quantity and the

percentage of chance in price

∵ The percentage of increasing of quantity = (new - old)/old

∵ New = 619000 and old = 430000

∴ The percentage of increasing of quantity =

$\frac{619000-430000}{430000}*100=43.95$ %

∵ The percentage of decreasing of price = (old - new)/old

∵ New = $2450 and old = $2950

∴ The percentage of decreasing of price =

$\frac{2950-2450}{2950}*100=16.95$ %

- Lets substitute these values in the equation above

∴ Price of elasticity of demand = 43.95% ÷ 16.95% = 2.59

* The price of elasticity of demand is 2.59

On Saturday, Cannor drives 62 1/4 miles each hour. If he travels 4 hours, how many miles does he travel altogether?

Kisachek [45]

Answer:

he travels 249 miles on saturday

Step-by-step explanation:

62.25 x

1 = 4

you must multiple the distance travled in one hour by the number of hours of driving. In this case 4. This is if he did not change speeds ;)

4 x 62.25 = 249 miles

Hope this helps :) Please mark brainliest if you see fit :)

What is the area of the gray triangle shown?

DanielleElmas [232]

Answer:

The area of the triangle is basically half the area of the square, so we only need to find the area of the square and divide it by 2:

S = (15 · 15)/2 = 112.5 (square units)
