A child is hopping along a sidewalk. The ratio table below shows the comparison between the number of hops and the distance trav
GaryK [48]

Answer:

First we rewrite the table:

20    30

50    75

80    120

150   ?

We observe that for each 30 number of hops, the distance increases by 45 feet.

We must find the slope of the line:

m = (y2-y1) / (x2-x1)

m = (75-30) / (50-20)

m = 1.5

Then, the line is:

y = 1.5x

We substitute x = 150

y = 1.5 * (150)

y = 225

Answer:

Find the ratio of hops to distance traveled (1: 1.5), then multiply 150 by 1.5.Step-by-step explanation:

What is the length of side ac of the triangle
Margarita [4]

Answer:

AC = 25

Step-by-step explanation:

Since ∠A = ∠C then the triangle is isosceles, thus BC and AB are congruent, that is

BC = AB, substitute values

7x - 1 = 5x + 5 ( subtract 5x from both sides )

2x - 1 = 5 ( add 1 to both sides )

2x = 6 ( divide both sides by 2 )

x = 3

Hence

AC = 6x + 7 = (6 × 3) + 7 = 18 + 7 = 25

zloy xaker [14]

Answer:

Step-by-step explanation:

1

the initial level is below normal so it is represented by a negative number. the level continued to decrease in June and July so those changes are also represented by negative numbers. find the sum of these values to find what the new level was with respect to the normal level

2

write the mixed numbers as improper fractions

3

get common denominator

4

add the numerators since all the numbers are negative and have a common denominator. write the improper fraction as a mixed number
