V = 1/3* h * r^3 pi
V ' = 1/3* h/3* (2r)^3 pi = h/9 * 8r^3 * pi

V ' / V = (h/9 * 8r^3 * pi)  ÷ ( 1/3* h * r^3 pi ) = (8 * 3)/ 9 = 8 /3

Triangle pqr is a right triangle. what is the best approximation of the length of segment pq? (Note:tan76°)
andrew11 [14]

Answer:

PQ = 16.04cm

Step-by-step explanation:

θ = 76°

QR = 4cm

PQ = ?

Since it's a right angle triangle,

QR = adjacent

PQ = opposite

Tanθ = opposite/adjacent

Tan76 = pq / 4

PQ = 4tan76

PQ = 4 * 4.010

PQ = 16.04cm

Solve for x 8/14=x/37
Setler79 [48]

Hello there!

\frac{8}{14}=\frac{x}{37}

Explanation:

↓↓↓↓↓↓↓↓↓↓↓

First you had to switch sides of the equation.

\frac{x}{37}=\frac{8}{14}

Then you had to cancel by the common factor of 2.

\frac{x}{37}=\frac{4}{7}

You had to multiply by 37 from both sides of the equation.

\frac{37x}{37}=\frac{4*37}{7}

Simplify it should be the correct answer.

x=\frac{148}{7}

<em><u>Answer⇒⇒⇒x=148/7 </u></em>

Hope this helps!

11. Lucas is making one dozen sn
anygoal [31]

Answer:

Lucas needs 12 cups of dried cherries and 24 cups of dried apricots to make one dozen of snacks for his team

Step-by-step explanation:

For each snacks Lucas uses one cup of dried cherries and 2 cup of dried apricots. One dozen of snack  contains a total of 12 snacks. Therefore to prepare 12 snacks (one dozen) the number of dried cherries and dried apricots can be gotten by multiplying the number of dried cherries and dried apricots required for each snack by 12.

Number of dried cherries = 1 cup for each snack × 12 snacks = 12 cups

Number of dried apricots = 2 cup for each snack × 12 snacks = 24 cups

Lucas needs 12 cups of dried cherries and 24 cups of dried apricots to make one dozen of snacks for his team
