how would I write an equation for the following problem? Find 4 consecutive even numbers whose sum is 156.

Answers

2n+(2n+2)+(2n+4)+(2n+6)=156

Therefore:

2n+2n+2+2n+4+2n+6=156

8n+12=156

8n=156-12

8n=144

n=144/8

n=18

The four consecutive even numbers are:

36, 38, 40, 42

There are 60 tables in a restaurant, with 25% of them seating 22 people. The tables remaining seat 44 people. How many seats are there in the restaurant?

Answers

find how many seat 22 people
25% of 60=1/4 times 60=15 tables

60-15=45 tables that seat 44

number of seats=22 times number of 22tables+44 times number of 44tables
number of seats=22 times 15+44 times 45
number of seats=330+1980
number of seats=2310 seats

Which of the following scenarios has a lower y-intercept than y = 4x + 5 ?(a.) A 50 gallon tub is draining. Every 2 minutes, the amount of water decreases by 2 gallons.

(b.) Reginaldo had $17 in his account and for every book he buys, it costs him $4.

(c.) Sydney has collected 8 postcards. Each time a friend comes to visit, Sydney gives her a postcard.

(d.) Owen has 3 pets. He receives a new pet each time he has a birthday.

The key to this question is "What do you start with?" All of them (except D) start with something and then a condition reduces the starting point.
A
The condition (at zero) starts with 50 gallons. Every 2 minutes the amount taken away is 2 gallons.
The equation looks like this
y = -2x + 50
So what do you start with? You started with 50 gallons. That's your y intercept. It's big. A is NOT the answer.

B
Renaldo starts with 17 dollars. He hasn't done anything, and he still has 17 dollars. If he buys a book, he has 4 dollars less. So his equation is
y = -4x + 17. The y intercept is 17 if he has bought no books. The answer is NOT B

C
Sydney starts with 8 postcards. Every time a friend comes, Sydney has 1 less post card. Her equation is
y = 8 - x That's not the answer either.

D
What do you start with? 3 pets, correct? Every birthday Owen get's one more. But the starting point is three. So his equation is
y= 3 + x where x is the number of birthdays.
D has the lowest starting point.

3. The side of a square is 20 cm long. What is the circumference of the circle when … a. The circle is inscribed within the square?
b. The square is inscribed within the circle?

Answers

Answer:

a. 20π cm.

b. 20(√2)π cm,

Step-by-step explanation:

a. The diameter (d) of the circle = side of the square = 20 cm.

So the circumference = π d = 20π cm.

b. In this case the diameter = the length of the diagonal of the square.

The diagonal = diameter of the circle =sqrt ( 20^2 + 20^2) = √800 = 20√2.

So the circumference = πd = 20(√2)π.
