Over the course of a month, Katniss caught three times as many squirrels as deer. She also caught five less rabbits than squirre

NeTakaya

Answer:

She caught 10 rabbits

Step-by-step explanation:

Given

Represent Rabbits with R; Squirrels with S and Deer with D

$S = 3D$

$S = R - 5$

$S + R+ D = 10 +4D$

Required

Determine the value of R

$S + R+ D = 10 +4D$

Solve for R

$R = 10 + 4D - D - S$

$R = 10 + 3D - S$

Recall that $S = 3D$

Substitute 3D for S

$R = 10 + 3D - 3D$

$R = 10$

Hence;

<em>She caught 10 rabbits</em>

B. Tennis: Length- 36, Width- 72

B. Basketball: Length- 50, Width: 94

Step-by-step explanation:

A. Tennis

perimeter equation: P= 2L+2W

P=2(x)+2(2x+6) simplify

P= 2x+4x+12

P=6x+12

A. Basketball

P= 2(1/2x+32)+2(3x-14) simplify

P=7x+36

B. Tennis and basketball

just plug in 36 for x for the original lengeth and width equations for each court

What is the radius of a sphere with a volume of 7961 cm", to the nearest tenth of a<br> centimeter?

statuscvo [17]

Answer:

12.4 cm

Step-by-step explanation:

Use the sphere volume formula, V = $\frac{4}{3}$ $\pi$ r³

Plug in the volume and solve for r, the radius:

V = $\frac{4}{3}$ $\pi$ r³

7961 = $\frac{4}{3}$ $\pi$ r³

1900.55 = r³

12.39 = r

So, the radius of the sphere is approximately 12.4 cm
