Hey There! :)

Solve for g.
$g/20=12/48
$
Isolate the variable; Multiply both sides by 20.
$(g/20)*20=(12/48)*20$
$g=240/48$
$g=5$

Hope this helps.

The function f(r) = π determines the area of a circle in cm2, A, in terms of the radius of the circle in cm, r. a. Write a funct

ollegr [7]

Answer with Step-by-step explanation:

We are given that

a. $f(r)=\pi r^2$

$A=\pi r^2$

$r^2=\frac{A}{\pi}$

$g(A)=r=\sqrt{\frac{A}{\pi}}$

b.Radius=2.58 cm

Substitute the values in the formula and $\pi=3.14$

$f(2.58)=3.14(2.58)^2=20.9 cm^2$

Hence, the area of circle =20.9 square cm

c.Area of circle=1530 square cm

$r=\sqrt{\frac{1530}{3.14}}=22.07 cm$

Hence, the radius of circle=22.07 cm

c.Area of circle of radius 15.2 cm= $A_1=3.14(15.2)^2=725.47 cm^2$

Area of circle of radius 15.1 cm= $A_2=3.14(15.1)^2=715.95 cm^2$

$A_1-A_2=725.47-715.95=9.52 cm^2$

Hence, the area of circle whose radius is 15.2 cm is greater than the area of circle of radius 15.1 cm by 9.52 square cm .

Describe a situation with an output of area in square feet that can be modeled using the function f(x) = (x)(2x + 5).

Iteru [2.4K]

The given function is
<span>f(x) = (x)(2x + 5)
and this should describe a situation with an output of area in square feet.

A rectangular plot with the length 5 feet longer than twice the width has an area that is equal to
</span>f(x) = (x)(2x + 5)

HELP plz 20 pionts PLZ HELP me PLZ HELP me

k0ka [10]

A) every 50 students is 1 representative, so:

r = (a+b+c+d+e)/50

b) (1587 + 985 + 2052 + 824 + 752)/50 = 6200/50 = 124 representatives.

Our answer makes sense since for every representative, there are 50 students. And 50*124 = 6200 total students.
