Formula:

V = 1/3 * b^2 * h

Plug in what we know:

V = 1/3 * 7^2 * 16

Simplify the exponent:

V = 1/3 * 49 * 16

Multiply all 3 numbers together:

V = 261.3cm^3

What is the value of y?<br><br> 39<br> 34<br> 16<br> 20 <br><br> one of those number is the answer
melomori [17]

Answer:

20

Step-by-step explanation:

we see here that angle RPN is 180 degrees. SPM is 90 degrees so

angle RPS + angle SPM + angle MPN = 180 degrees

(4y - 10) + 90 + y = 180

(4y - 10) + y = 90

5y - 10 = 90

5y = 100

y = 20

The first step for solving this is to cancel equal terms on both sides of the inequality.
- \frac{x}{2} < 0
Now multiply both sides of the inequality by -2 and flip the inequality sign.
-2 × (- \frac{x}{2}) > -2 × 0
Remember that multiplying two negatives together always equals a positive,, so the expression changes to the following:
2 × \frac{x}{2} > -2 × 0
Reduce the numbers with 2.
x > -2 × 0
Any expression multiplied by 0 equals 0,, so the correct answer to your question will be:
x > 0

The map below shows the path that Jin walked this morning. According to his pedometer, the total distance of this path was 2.3 k
max2010maxim [7]

Answer:

5 centimetres = 1 kilometre

Step-by-step explanation:

First add up the distances measured on the map.

1.1+4.8+2.2+3.4=11.5 cm

Based on this, since the number of cm is greater than the number of km, we can figure out that each cm should not be multiplied to get the km, so we can eliminate the first two answers.

Next write an equation to represent finding the scale

x=scale

11.5=2.3x

Now solve for the scale

11.5/2.3=2.3x/2.3

5=x

Therefore the scale is 5 centimetres = 1 kilometre

Julia is using the distributive property to simplify 3(x+2) find her mistake and correct it.
Zanzabum

Answer:

The answer is 3x+6

Step-by-step explanation:

You multiply what's on the outside of the parenthesis by everything on the inside, so you would do 3 times x and 3 times 2. They don't combine because they are like terms.
