Answer:

300

Step-by-step explanation:

Let y = unknown number

30% of y = 90

⇒ 0.3 × y = 90

⇒ y = 90 ÷ 0.3

⇒ y = 300

It's 300. 90x100÷30 = 300. :)

y= 3

x= 1

Step-by-step explanation:

7x+y=10

3x-2y= -3

solve the equation

y=10-7x

3x-2y= -3

substitute the value of y into an equation

3x-2(10-7x)= -3

distribute

3x-20-14x= -3

add 14x from both sides

17x-20= -3

add 20 from both sides

17x=17

divide both sides by 17

x=1

substitute the value of x into an equation

y=10-7•1

multiply 7 to 1

y=10-7

subtract

y=3

At a campground, a rectangular fire pit is 3 feet by 2 feet. What is the area of the largest circular fire that

AysviL [449]

The area of the largest circular fire pit is 452 square inches.

Explanation:

Given that at a campground, a rectangular fire pit is 3 feet by 2 feet

The radius is given by 1 feet.

The area of the largest circular fire is given by

$A=\pi r^2$

Substituting the values in the formula, we get,

$A=(3.14)1^2$

$A=3.14 \ ft^2$

Thus, the area of the largest circular fire is 3.14 square feet.

<u>To convert feet to inches:</u>

The feet can be converted into inches by multiplying by 12.

Thus, we have,

$1 \ft= 12 \ inches$

Hence, we have,

$Area= 3.14\times 12^2$

Simplifying,we get,

$Area= 3.14\times144$

$Area=452.16 \ in^2$

Rounding off to the nearest square inch.

Thus, we have,

$Area= 452 \ in^2$

Thus, the area of the largest circular fire pit is 452 square inches.
