A bowling ball weighs 5.61 kg, and a bowling pin weighs 1.57 kg. About how many bowling pins would equal the weight of the bowling ball?


Answer 1
Answer: 3 bowling pins would be equal to the weight of the bowling ball.

You find the answer by dividing the amount that a bowling ball weighs (5.61 kg) by the amount that a bowling pin weighs (1.57 kg) which would give you 3 remainder 57 .. So it's 3.

Angle A and B are supplementary. Angle a has a measure of 80. What is the measure of angle B? The measure of angle B is


Well when two angles are supplementary they equal 180.
So if angle A is 80 degrees then that would mean that angle B equals 100 degrees.

Given: g(x) = √ x− 3 and ℎ(x) = 2x − 7. a) What are the restrictions on the domain of g° ℎ? Show your work for full credit.

xx ≥ _____________

b) What is g(ℎ(13))? Simplify your answer in lowest terms. Show your work for full credit



Restrictions on the domain: x>=5

g(h(13)) = ±4

Step-by-step explanation:

g° ℎ is the composite function

We stick the function h in for x in the function g

g(x) = sqrt(x-3)

h(x) = 2x-7)

g(h(x)) = sqrt( 2x-7 -3)

g(h(x)) = sqrt( 2x-10)

The restrictions on the domain , or the allowed values of x

sqrt (2x-10) >= 0

Square each side

2x-10 >= 0

2x>= 10

Divide by 2


Let x=13

g(h(13)) = sqrt( 2*13-10)

Please help answer this please Innes is starting a wedding photography business. She initially spent $659 on one-time expenses like camera equipment and editing software and then she will spend $69 per wedding to print photographs after each photo shoot. She will charge $90 per wedding photo shoot.

Innes wants to know how many weddings she must photograph in order to make a profit, so she writes the following inequality:

90n < 659 + 69n, where n = the number of weddings she photographs

Innes’ equation is not correct. In the space below identify and explain her error in 1-3 complete sentences.



The inequality symbol in the given inequality is backwards. It should be: ">"

Step-by-step explanation:

Innes wants her net earnings per photo shot to be larger than her initial expenditure of $659, so this number (659) should be on the angle side of the inequality symbol. Then, her net earnings are: 90n - 69n (because she charges $90 per photo shot but will always have $69 expenses per photo shot. Therefore she wants her net income of 90n - 69n to be larger than the initial investments of $659:

90n - 69n > 659, which can also be written as: 90n > 659 +69n

Notice the inequality symbol goes opposite to the inequality presented in the question.
