Answer:   h=12.8in

a Base edge 15   in

V Volume 960  in³

Using the formula

V=a2h

3

Solving for h

h=3V

a2=3·960

152=12.8in

What type of endorsement is illustrated by the following example:
Bezzdna [24]
When receiving a check from someone, you'll see that there are lines on the back. Those lines are for the check to be endorsed so you can cash it or deposit your money. Most of the time you'll just sign the back to endorse it and put it in your account or get money in return. However, there are special cases that can show where the money should go. Here are different types of endorsements:

1. Blank endorsements have just your signature on the back. Anyone can cash or deposit a check with this endorsement.

2. Restrictive endorsements have "For Deposit Only" on the first line, then your signature below that. This type of check can only be deposited, not to be cashed for money.

3. Special endorsements are for giving your check to another person. This check can only be deposited or cashed by the person designated on the back. For this endorsement, you would write "Pay to the order of" and then the person's name you want to give the check to. You would then sign your name underneath that. 

As seen in your question, Isis Love is signing it as a special endorsement<em />. She is giving her check to Mike Lopez so his name follows "Pay to the order of". The numbers at the bottom would represent the bank account number.

Please help me I will really appreciate it!!!

Answer:

<em />\displaystyle  r=\sqrt[3]{\frac{3V}{4\pi}}<em />

<em>The last option matches the correct solution</em>

Step-by-step explanation:

<u>Equation Solving</u>

We have the following equation:

\displaystyle V=\frac{4}{3}\pi r^3

And it's required to solve it for r.

Solving this equation needs to perform some operations to have the r isolated from any other variables or constants.

It can be done by conveniently operating on both sides as follows:

Eliminate the denominator by multiplying by 3:

\displaystyle 3V=4\pi r^3

Move 4\pi to the other side by dividing by 4\pi:

\displaystyle \frac{3V}{4\pi}= r^3

Swapping sides to have r at the left side:

\displaystyle  r^3=\frac{3V}{4\pi}

Finally, take the cubic root and leave r alone:

\displaystyle  r=\sqrt[3]{\frac{3V}{4\pi}}

The last option matches the correct solution

Andrej [43]

Answer:

13.7 ft^2

Step-by-step explanation:

1. Find the radius of the semicircle by dividing the diameter by 2 to get 1.8

2. Find the area of the semicircle.  Do this by substituting the equation to find the area of a semicircle with the numbers given and solving.  3.14(1.8^2)/2 = 5.0868

3. Find the area of the triangle.  Do this by substituting the equation to find the area of a semicircle with the numbers given and solving.  1/2(3.6*4.8) = 8.64

4.  Add both your numbers together to get 13.7268

5. Round to the nearest 10th to get 13.7 ft^2

a painter bought 8 gallons of paint,just enough to cover two rooms.one room is twice the size of the other and requires 3 coats
bija089 [108]
Let x be the size of the small room and 2x, the big room

The larger room requires 3 coats and the smaller, 2 coats


All requires exactly 8 gal.


2.x + (2x).3 = 8 Gal,  8x = 8 and x = 1 (size of te smallest)

if it's the small room, then it will need 2 coats or 2x1 = 2 Gal,  and the paint left is 8-2  = 6 Gal.

if it's the large one, 6x or 6 Gal, and remaining 2 Gal
