\sf{\qquad\qquad\huge\underline{{\sf Answer}}}

Here we go ~

Given :

  • diameter = 14 ft, radius = d/2 = 14/2 = 7 ft

  • take pi = 3

Let's calculate volume of the sphere ~

\qquad \sf  \dashrightarrow \:v =  \dfrac{4}{3}  \pi {r}^{3}

\qquad \sf  \dashrightarrow \:v =  \dfrac{4}{3}   \sdot3 \sdot {7}^{3}

\qquad \sf  \dashrightarrow \:v = 4 \sdot343

\qquad \sf  \dashrightarrow \:v = 1372 \:  \: ft {}^{3}

Debra travels a distance of 2 miles in 1 minute how much distance can she cover in 25 minutes
Marta_Voda [28]

Debra will travel 50 miles in 25 minutes

Step-by-step explanation:

Given

distance = 2 miles

Time = 1 minute

Other time = 25 minutes

We can use the proportions to find the number of miles debra will travel in 25 minutes

So,

Distance:Time::Distance:Time\\2:1::Distance:25\\\frac{2}{1} = \frac{Distance}{25}\\Distance = 25 *2\\= 50\ miles

Hence,

Debra will travel 50 miles in 25 minutes

Solve for z<br> -p(d+z) = -2z+59−p(d+z)=−2z+59
alexira [117]

-p(d+z)=-2z+59\qquad\text{use distributive property}\\\\-pd-pz=-2z+59\qquad\text{add pd to both sides}\\\\-pz=-2z+pd+59\qquad\text{add 2z to both sides}\\\\2z-pz=pd+59\\\\z(2-p)=pd+59\qquad\text{divide both sides by}\ (2-p)\neq0\\\\\boxed{z=\dfrac{pd+59}{2-p}}

The angled of a triangle are in the ratio of 2:3:4 find angles in degrees
jeyben [28]

40°, 60° and 80°

sum the parts of the ratio 2 + 3 + 4 = 9

The sum of the angles in a triangle = 180°

Divide 180 by 9 to find one part of the ratio

\frac{180}{9} = 20° ← 1 part of the ratio

2 parts = 2 × 20 = 40°

3 parts = 3 × 20 = 60°

4 parts = 4 × 20 = 80°

The angles in the triangle are 40°, 60° and 80°
