Answer:

{January, February, March, April, May, June, July, August, September, October, November}

Step-by-step explanation:

The set is formed by months of year with indexes larger than 0 and lesser than 12.

The year starts at month 1, which is January, and finishes at month 12, which is December.

Since we want lesser than 12, December is not part of the set. So the answer is given by:

{January, February, March, April, May, June, July, August, September, October, November}

Instructions: Factor 715 as a product of primes.

Drupady [299]

Answer:

{1, 5, 143}

Step-by-step explanation:

715 is evenly divisible by 5, so one factor of 715 is 5 and the next is 715/5, or 143. 143 is not factorable further. Thus, the factors of 715, in ascending order, are 1, 5 and 143.

April sold 75 tickets to the school Christmas play and collected $495. If adult tickets cost $8 and children tickets were $5 how

riadik2000 [5.3K]

Answer:

Step-by-step explanation:

~First we have to write our two equations that are:

1. 8x+5y=$495(becoz the no. of adult tickets is unknown and children is unknown we use variables instead and multiplying them with the amount of money for each gives us 495)

2. x+y=75( No. of adult tickets and children altogether gives us 75)

~Use the substitution method by using any of the equations and putting the variable you want as the subject and then putting its values in the next equation:

x+y=75

x=75-y

~Substitute to find y(no. of children’s ticket)

8x+5y=495

8(75-y)+5y=495

600-8y+5y=495

-8y+5y=495-600

-3y=-105

y=-105/-3

y=35

Therefore, the no. of children tickets is 35.

~Substituting y in the substitution equation(x=75-y):

x=75-35

x=40

Therefor no. of tickets sold to adults is 40.

~Final answers:

Adults=40

Children=35

An elevator is rated to safely hold ten 250 lb people. The elevator is loaded as follows: three 600 lbs cartons of books, Jim (1

iris [78.8K]

To do this, we will need to find how much the elevator can hold in all. Multiply 10 by 250 to get 2500. Since it can also hold 10% more, multiply 2500 and 0.10 to find out how much 10% is. You get 250. Add 2500 and 250 to get how much the elevator can safely hold. It would be 2750.

To find out how much more weight can be added, first find out how much weight is on the elevator collectively. (books) 600+ (Jim) 180+ (Gavin) 330 + (Deb) 250 + (Susan) 120 = 1480. Subtract this from the amount the elevator can hold, and you get how much more weight can be added. 2750-1480= 1270.

The elevator can hold 1270 more ibs.

Why do you think it’s important for students to learn about math

marissa [1.9K]

Answer:

Step-by-step explanation:

Math is in our everyday lives. We calculate and use math in our daily lives without knowing it. By learning math, we build on useful knowledge that will help us have a better future. For example, learning how to pay taxes acquire math. Grocery shopping needs you to find the cost of the product you’re buying. When we learn math, we gain knowledge and we can pass that knowledge to our future generations so more and more people can use it to find better jobs, make your life easier, and so much more. Therefore, that is why it is important for students to learn about math.
