Answer:

12

Step-by-step explanation:

Use the Pythagorean theorem which is a^2 + b^2 = c^2

c is hypotenuse and a and b are the legs

we need to find a^2 so

a^2 + 16^2 = 20^2

a^22 + 256 = 400

then subtract 256 from 400

a^2 = 144

square root 144

= 12

Round tables seating 8 people and rectangular tables seating 12 people are being used at a banquet for 8th graders. The ratio of
Tamiku [17]

Answer:

<u>36 tables are used to seat  the students at the banquet: 12 rectangular and 24 round.</u>

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

Round tables = 8 seats

Rectangular tables = 12 seats

Ratio of round tables to rectangular tables = 2:1

Number of students = 336

2. How many tables are used to seat 336 students at the banquet, if no table has an empty seat?

x = Number of rectangular tables

2x = Number of round tables

Let's solve for x, using this equation:

12x + 8 (2x) = 336

12x + 16x = 336

28x = 336

x = 336/28

x = 12 ⇒ 2x = 24

12 + 24 = 36

<u>36 tables are used to seat  the students at the banquet: 12 rectangular and 24 round.</u>

Please help! I have no idea what to do. I couldn't even guess an answer.
yulyashka [42]

y - y1 = m(x - x1)

Plug in:

Slope = m = 4

Point = (x1,y1) ----> (-3,7)

y - 7 = 4(x - -3) //Solve for y

y - 7 = 4(x + 3) //Answer

y - 7 = 4x + 12

y = 4x + 12 + 7

y = 4x + 19

Answer: B

//Hope it helps
