PLEASE HELP! Daniela has a rectangular yard with a pool in the shape of a semicircle. How many square feet of grass does Daniela

GalinKa [24]

Answer:

Part 1) Area of rectangle $3,600\ ft^{2}$

Part 2) Area of semicircle $1,413\ ft^{2}$

Par 3) Total area of grass $2,187\ ft^{2}$

Step-by-step explanation:

we know that

The total area of grass is equal to the area of rectangle minus the area of semicircle

step 1

Find the area of rectangle

The area of rectangle is equal to

$A=45*80=3,600\ ft^{2}$

step 2

Find the area of semicircle

The area of semicircle is equal to

$A=\frac{1}{2}\pi r^{2}$

we have

$r=60/2=30\ ft$ -----> the radius is half the diameter

substitute

$A=\frac{1}{2}(3.14)(30)^{2}$

$A=1,413\ ft^{2}$

step 3

Find the total area of grass

$3,600\ ft^{2}-1,413\ ft^{2}=2,187\ ft^{2}$

1. un numar se mareste cu 4 iar rezultatul se mareste de 4 ori. noul rezultat micsorat cu 4 se imparte la 4 si se obtine 4.aflat

Marat540 [252]

Răspuns:

Explicație pas cu pas:

Fie numărul = x

x + 4 = e - - (1)

e * 4 = f - - - (2)

Ecuația 2 - 4 împărțită la 4 = 4

(f - 4) / 4 = 4

Crucea se înmulțește

f - 4 = 16

f = 16 + 4

f = 20

Rezultatul 1 împărțit la 4 este egal cu 4

Prin urmare,

e = f / 4

f = 20

e = 20/4

e = 5

De la (1)

x + 4 = e

x + 4 = 5

x = 5 - 4

x = 1

In 2016 49% of all degrees granted were bachelors degrees if 1,920,718 students earned bachelors degrees how many total degrees

JulsSmile [24]

Answer:

Step-by-step explanation:

This problem is focused on percentages.

Now given that 49% of a number is 1,920,718

we can say let the number be x

so 49% of x= 1,920,718

now expressing this problem mathematically we have

(49/100)*x= 1,920,718

0.49x= 1,920,718

divide both sides by 0.49 we have

x= 1,920,718/0.49

x= 3919832.65306

Therefore the total that were granted degree that year was 3919832.65306
