Answer:

r=\dfrac{2}{3}\ yards

Step-by-step explanation:

Given that,

The volume of a sphere is, V=\dfrac{32}{81}\pi cubic yards

We need to find the radius of the sphere. The formula for the volume of a sphere is given by :

V=\dfrac{4}{3}\pi r^2

Put all the values,

\dfrac{32}{81}\pi=\dfrac{4}{3}\pi r^3\\\\r^3=\dfrac{8}{27}\\\\r=\dfrac{2}{3}\ yards

So, the radius of the sphere is equal to \dfrac{2}{3}\ yards.

solong [7]
<span>y(t) = a exp(3t) + b exp(4t) conditions, y(0) = 3 y'(0) = 3 y(0) = a exp(3 x 0) + b exp(4 x 0) = a exp(0) + b exp(0) = (a x 1) + (b x 1) = a + b y'(0) = 0 so the linear equation is, a + b = 3</span>

What is the distance around a triangle that has sides measuring 21/8 feet, 31/2 feet and 21/2 feet?
sleet_krkn [62]
Add all of the sides together. Make sure to use a common denominator because you are adding fractions. Don't forget your unit label (feet)
\frac{21}{8} + \frac{31}{2} + \frac{21}{2}
\frac{21}{8} + \frac{124}{8} + \frac{84}{8}
\frac{229}{8} feet

Two glasses of milk and three snack bars have a total of 72 carbs. and 4 glasses of milk and 2 snack bars have a total of 88 car
melisa1 [442]

Answer:

one glass of milk = 15 carbs

one bar = 14 carbs

Step-by-step explanation:

let 'm' = one glass of milk

let 'b' = one snack bar

system of equations:

2m + 3b = 72

4m + 2b = 88

I used the elimination method and multiplied the 1st equation by -2

  -4m - 6b = -144

+  <u>4m + 2b =  88</u>

           -4b = -56

              b = 14

now solve for 'm'

2m + 3(14) = 72

2m + 42 = 72

2m = 30

m = 15
