A city park has a large circular garden with a path around it. The diameter of the garden is 60 feet. Jason works for the City P

Angelina_Jolie [31]

Answer:

He will cover 2,827.433 feet² area of the park with plant food.

Step-by-step explanation:

The diameter of the garden is 60 feet and the radius will be 60 feet/2 = 30 feet.

diameter= 60 feet

radius = diameter/ 2= 60/2= 30 feet

The area of the circle can be found by the formula πr²

Area= πr²=π(30)²

Area = 900π= 2,827.433 feet²

He will cover 2,827.433 feet² area of the park with plant food.

Find the percent cost of the total spent on each:

natta225 [31]

The right answer is 18%,61%,21%

Step-by-step explanation:

Given,

Amount spent on equipment = $46

Amount spent on fees = $152

Transportation = $52

Total spent = Equipment + Fees + Transport

Total spent = 46+152+52 = $250

Percent spent on equipment = $\frac{Amount\ spent\ on\ equipment}{Total\ spent}*100$

Percent spent on equipment = $\frac{46}{250}*100 = 18.4\%$

Rounding off to nearest percent

Percent spent on equipment = 18%

Percent spent on fees = $\frac{Amount\ of\ fees}{Total\ spent}*100$

Percent spent on fees = $\frac{152}{250}*100 = 60.8\%$

Rounding off to nearest whole percent

Percent spent on fees = 61%

Percent spent on transportation = $\frac{Amount\ spent\ on\ transportation}{Total\ spent}*100$

Percent spent on transportation = $\frac{52}{250}*100 = 20.8\%$

Rounding off to nearest whole percent

Percent spent on transportation = 21%

The right answer is 18%,61%,21%

Find the inverse of square root f(n) = n – 3.

pogonyaev

Answer:

$f'(n) = n + 3$

Step-by-step explanation:

Given

$f(n) = n - 3$

Required

The inverse

$f(n) = n - 3$

Replace f(n) with y

$y = n - 3$

Swap positions of y and n

$n = y - 3$

Make y the subject

$y = n + 3$

Replace y with f'(n)

$f'(n) = n + 3$

$30 is 60% of what number?

ankoles [38]

$30 is 60% of $50.

100 % is the whole figure. Based on the problem, 100 % is separated into two parts, 60% and 40%

100% = 60% + 40%

To get the number where $30 is 60%. Let X be the 100% number.

First, divide all number by 100% to remove the percentage and get the whole number.

100%X = 30 + 40%X

X = 30 + 0.40X
X - 0.40X = 30

0.60X = 30

To get X, divide both sides by 0.60

X = 30 / 0.60
X = 50

To check: Substitute all X by 50.

X = 30 + 0.40X

50 = 30 + (0.40*50)
50 = 30 + 20
50 = 50 EQUAL. CORRECT.
