A football team scored 3 touchdowns 3 extra points and 4 field goals if each touch down is 6 points extra point is 1 and each field goal is 3 points how many total points did the team scored

Answers

I'm pretty sure the answer is 33, hope this helps!
Yes! the answer is 33, how I got my answer!

I first multiplied the touchdowns which equals 6 points per touchdown, and there are 3 so multiply, 3×6=18, and I multiplied extra points which equals 1 point for extra points and there are 3 extra points so multiply, 3×1=3, last I multiply field goals which equals 3 points per field goal and there are 4 of them so multiply, 4×3=12. now I add all the sums together, 18+3+12=33.

Answers

Answer:

11 L of 20% juice and 4 L of 5% juice

Step-by-step explanation:

Let

x L = amount of 20% juice

y L = amount of 5% juice

20% juice:

Amount = x L

Amount of juice L

5% juice:

Amount = y L

Amount of juice L

16% juice:

Amount = 15 L

Amount of juice L

We mixed x L of 20% juice with y L of 5% juice to get 15 L of 16% juice, so

You want to hang a chandelier over a table from a 10-foot ceiling using a brass chain. The light should be 6 feet from the floor. The fixture is 18 inches high. Each link is 1 ¼ inches. how many links are in the chain?

Answers

Answer:

24 links.

Step-by-step explanation:

You want to hang a chandelier over a table.

It is given that ceiling is 10 foot high. The light should be 6 feet from the floor.

10 - 6 = 4 feet from the ceiling.

4 feet = 48 inches.

The fixture is 18 inches high. So chain would be = 48 - 18 = 30 inches

If each link is inches or 1.25 inches.

For 30 inches chain, number of links would be = 30 ÷ 1.25 = 24 links.

24 links are used in the chain.

2.5 ft of chain = 30 inches 
30/1.25 = 24 links 

24 links should be your answer!

I hope this helps you and have a great day!!:)

The volume of a rectangular prism is given by the formula V = lwh, where l is the length of the prism, w is the width, and h is the height. Suppose a box in the shape of a rectangular prism has length (2a + 11), width (5a – 12), and height (a + 6). Which expression represents the volume of the box?

Answers

V = lwh
v = (2a + 11)(5a - 12)(a + 6)
v = (2a + 11)(5a^2 + 18a - 72)
v = (10a^3 + 36a^2 - 72a + 55a^2 + 198a - 792)
v = 10a^3 + 91a^2 + 126a - 792

A rectangular swimming pool is 8ft deep. One side of the pool is 4.5 times longer than the other. The amount of water needed to fill the swimming pool is 3600 cubic feet. Find the dimensions of the pool.

Answers

Dimensions of pool are length 10 feet and width 45 feet and height 8 feet

Solution:

Given that,

Rectangular swimming pool is 8ft deep

Height = 8 feet

The amount of water needed to fill the swimming pool is 3600 cubic feet

Volume of pool = 3600 cubic feet

Let "x" be the length of rectangular pool

One side of the pool is 4.5 times longer than the other

So, width of pool = 4.5x

The volume of pool is given as:

Substituting the known values,

Since length cannot be negative, ignore x = -10

Thus solution is x = 10

Therefore, length = x = 10 feet

width = 4.5x = 4.5(10) = 45 feet

Thus dimensions of pool are length 10 feet and width 45 feet and height 8 feet
