Choose an equivalent ratio. 4:9
A) 27:40
B) 27:18
C) 12:27
D) 16:27
Answer:
The answer is C.
Step-by-step explanation:
The answer is C because both numbers in 4:9 can be multiplied by the same factor (3) to get 12:27, the answer. No other choice works because they require two different number factors, not just one, which means they aren't equivalent ratios to 4:9.

The absolute value of −9 is positive.
Since −9 is 9 units to the left of 0, ∣∣−9∣∣=−9 .
−9 is farther to the right on the number line than −10 , so ∣∣−9∣∣>|−10| .
The absolute value of −9 is equal to the absolute value of 9.

Write the equation of the function g(x) if g(x) = f(x - 3) +1 and f(x) = x3 + 1.
Answer:
Solution,
f(x) = [tex]x^{3}[/tex] + 1
Put x = x - 3,
f(x - 3) = [tex](x-3)^{3}[/tex] + 1
Now,
g(x) = f(x - 3) + 1
or, g(x) =[ [tex](x-3)^{3}[/tex] +1 ] + 1
or, g(x) = [tex]x^{3} -9x^{2} + 27x - 1 + 1+1[/tex]
or, g(x) = [tex]x^{3} - 9x^{2} +27x + 1[/tex]

Noah was assigned to make 64 cookies for the bake sale. He made 25% MORE than that. How many cookies did Noah make? Explain how you got your answer.
PLEASE HELP MEH! WILL MARK BRAINLIEST!! DUE TODAY
Answer:
8 cookies were left after the bake sale. 72 were sold.
Step-by-step explanation:
64*1.25= 80
80*.9= 72
8
125% of 64 is equal to 80.
90% of 80 is equal to 72.
The number left was 10% of the number he made. The number he made was 125% of 64, so the number left was 8
10% × 125% × 64 = 0.125 × 64 = 8
thats all i could really come up with at the top of my head

At the sandwich shop, there is a sale each afternoon. A customer has a choice of
three types of bread and five different meats. Use the Fundamental Counting
Principle to determine how many combinations a customer can create ?
Answer:
15 combinations
Step-by-step explanation:
The fundamental counting principle states that if there are p ways to do one thing, and q ways to do another thing, then there are p×q ways to do both things. This means we need to multiply 3 by 5 to get the possible amount of combinations. This gets us 15. This means there are 15 combinations of bread and meat.
