If the square's area is 144, then the two sides are both 12.
The diameter is 3 times the side length (12): 3*12=36
The radius is half of the diameter: 36/2=18

The radius is 18

Helen [10]

Answer:

The exchange rate for Dollars to Euros is of 1.33.

Step-by-step explanation:

This question is solved by proportions, using a rule of three.

Exchange rate for Dollars to Euros.

We want to find the number of dollars in a euro.

In 375 euros, there are 500 dollars, so how many dollars in 1 euro?

375 euros - 500 dollars

1 euro - x dollars

Applying cross multiplication:

375x = 500

x = \frac{500}{375}

x = 1.33

The exchange rate for Dollars to Euros is of 1.33.

what are the domain and range of f(x) = 4x – 8? domain: {x | x is a real number}; range: {y | y &gt; –8} domain: {x | x is a rea
Serga [27]

Answer : domain: {x | x is a real number}; range: {y | y >- 8}

the domain and range of f(x) = 4^x – 8

For exponential function , there is no restriction for x

So domain is all real numbers

For exponential function , f(x) = a^x + b

The range is y > b

The range of f(x) = 4^x -8 is y> -8

domain: {x | x is a real number}; range: {y | y > –8}

75% as a decimal = 0.75

0.75 × 28 = 21

Your answer is 21
_____________________________________________________________

(2) Circumference = π · diameter

To find diameter, divide circumference by π

Circumference = 37.68

37.68 ÷ π = 11.99 = 12

The diameter is 12

Hope this helps :)
