The volume formula of a square pyramid is
V = 1/3 Bh (B is base).

Base area = 13 • 13
Base area = 169
Height = 11 m

Plug that in for:

V = 1/3 (169)(11)
V ≈ 619.66 or rounded is 619.67 cubic meters

5)Trevon's school is selling tickets to the annual dance competition. On the first day of ticket sales
the school sold 5 senior citizen tickets and 8 student tickets for a total of $94. The school took in
$164 on the second day by selling 10 senior citizen tickets and 13 student tickets. Find the price
of a senior citizen ticket and the price of a student ticket

Answers

Answer:

$8 for student tickets and $4.40 for senior tickets

Step-by-step explanation:

10 (5x +8y=94)

5 (10x +13y=164)

50x+80y=940

- 50x +65y=820

80y-65y= 940-820

15y= 120/15

y=8

(y is the cost of student tickets)

5x+8y=94

5x+8(9)=94

5x+72=94-72

5x=22/5

x= 4.4

12.4 gallon = 3.8*12.4

                  = 47.12 liters

So, there are 47.12 liters in 12.4 gallons of gasoline.

Reese's car has a 12 gallon gas tank. Right now, his gas gauge reads 1/3 full. If he buys 3 gallons of gas, what will the new reading on the gas gauge be?

Answers

Answer:

The new reading on the gas gauge will be will be 7/12 full

Step-by-step explanation:

From the question

Reese's car has a 12 gallon gas tank. Right now, his gas gauge reads 1/3 full.

Hence, the quantity of gas in the tank is currently:

12 gallon × 1/3

= 4 gallons

If he buys 3 gallons of gas

Total amount of gas = 4 gallons + 3 gallons

= 7 gallons of gas

The new reading on the gas gauge will be:

4 gallons of gas = 1/3

7 gallons of gas = x

Cross Multiply

4 gallons × x = 7 gallons × 1/3

x = 7 gallons × 1/3/4

x = 7/3 ÷ 4

x = 7/3 × 1/4

x = 7/12

The new reading on the gas gauge will be will be 7/12 full

Which combination of measurements could form a triangle?

B - 12m, 32m, 45m
C - 16m, 55m, 72m
D - 18m, 22m, 36m

Answers

Answers D

You divide all sides by 2, get your slope form and multiply by 7

Answer:

D - 18mm, 22mm, 36mm

Step-by-step explanation:

The only way for a triangle to be made, the 2 smallest side lengths must be greater than the longest side length. So for A through C, the smallest sides diden't add up to the longest side, therefore D is the only correct answer.
