Answer:

<u>The correct answer is A. 22 inches ³</u>

Step-by-step explanation:

Let's recall that the formula of the volume of a triangular pyramid:

Volume = 1/3 * Area of the base * height

Replacing with the values we have:

Volume = 1/3 * 11 inches² * 6 inches

Volume = 66/3

Volume = 22 inches ³

<u>The correct answer is A. 22 inches ³</u>

Peter wants to fence the park in front of his home on three sides which measure 152m 40cm, 205m 10cm, 310m 39cm. What is the tot
Tpy6a [65]

One centimenter is 0.01 meters. So, you can write the measures as

152.40\text{m},\quad 205.10\text{m},\quad 310.39\text{m}

Once this rewriting is done, getting the total length T is quite trivial, since all measurements are in the same unit, and we can simply sum everything:

T = 152.40+205.10+310.39 = 667.89

nikklg [1K]

Answer:

$35

Step-by-step explanation:

There is no attached diagram, but despite this, the tip amount can be calculated, since we know the total value of the expense in the restaurant and the percentage of tips they want to give, therefore it would be the multiplication of the total by the percentage like this:

140 * 0.25 = 35

$ 35 would be the value of the tip
