Your answer is B. 30. Here's why:

First, you do the parenthesis inside the parenthesis, which is 6 to the 2nd minus 4 to the 2nd. 6^2 is 36 and 4^2 is 16, and the difference is 20. Second we have 4x10÷20+1. With Order of Operations, you get 40÷20+1, then 2+1 and lastly 3. Finally after <u>these</u> parenthesis, you multiply by the 10 on the outside and your final answer, 30.

rita is make chili the recipe calls for 2 3/4 cups of tomatoes. How many cups of tomatoes,written as a fraction greater than one
Burka [1]
Given:
2 3/4 cups of tomatoes.

Number of cups of tomatoes written as a fraction greater than one.

2 3/4 is a mixed fraction. It is called such because it is a combination of a whole number and a fraction.

To find the number of cups of tomatoes written as fraction greater than 1, we need to convert the mixed fraction into an improper fraction.

Improper fraction is a fraction whose numerator is greater than its denominator.

2 3/4 ⇒ ((2*4)+3)/4 ⇒ (8+3)/4 ⇒ 11/4

11/4 is a fraction greater than one.

4/4 is a fraction that is equal to one.  So, any numerator that is greater than 4 is a fraction that is greater than one. In this case, it is 11/4.

ra1l [238]

Answer:

10)$38.50

11)D

Step-by-step explanation:

10) n = no. of rides

f(n) + g(n) = 1 + 2.5n

when n=15, 1 + 2.5(15)

= $38.50

11)f(x) = 4x³+3x²-5x+20

g(x) = 9x³-4x²+10x-55

(g-f)(x)=9x³-4x²+10x-55-(4x³

+3x²-5x+20)

= 9x³-4x²+10x-55-4x³

-3x²+5x-20

= 5x³-7x²+15x-75

(Correct me if i am wrong)
