**Answer:110**

**Step-by-step explanation:**

24.2/x = 22/100

Where x is the number we are looking for

cross multiply

24.2*100 = 2420

22*x=22x

22x=2420

22x/22=2420/22

x= 110

so 24.2 is 22% of 110

**Answer:**

C. (-1, 2) and (4, 7)

**Step-by-step explanation:**

It may be simplest just to try the answer choices.

We notice that y = x+3 is not satisfied by the points in choices A or D, so those can be eliminated.

__

The second equation can be written in vertex form as ...

y = (x -1)^2 -2

This equation is not satisfied by the points of choice B.

Using (-1, 4) (from choice B), we get 4 = (-1-1)^2 -2 = 4-2 = 2 . . . FALSE.

However it is a good match for the points of **choice C.**

Using (-1, 2) (from choice C), we get 2 = (-1-1)^2 -2 = 4 -2 = 2 . . . True

The appropriate choice is ...

** (-1, 2) and (4, 7)**

1) 16% —> .16

.16 x $32,788 = $839.3728

2) 85/3 = 28.333333......

28.33....... - 20 = 8.333...... or rounded

to 8.2

3) 1 lb = .454 Kilos

15 lbs = ?

.454 x 15 = 6.81

15 lbs = 6.8 Kilos

For t = 3 we get:

d(3) = 4.9*3^2 = 4.9*9 = 44.1

For t=6 we get:

d(6) = 4,9*6^2 = 176.4

The difference of these 2 values gets us distance traveled between t=3 and t=6 seconds.

d(6) - d(3) = 132.3 meters

if we divide this number with number of seconds that it takes coin to cover that distence we get:

132.3/(6-3) = 44.1

which is average speed between t=3 and t=6

answer is last option.

**Answer:**

14 square meters

**Step-by-step explanation:**

3*2=6

2*4=8

6+8=14
