Answer: Your answer is D.

Step-by-step explanation: $30 for each lawn, and he wants to have at least $180 next week. So:

180 / 30 = 6.

30 x 6 = 180.

So, 30x is greater than or equal to 180.

Answer:

d. 30x ≥ 180

Step-by-step explanation:

if x is the number of lawns and 30 is how much he gets for each lawn, it would be 30x. And in this situation, it needs to be equal to or more than 180.

Find the coordinates of the midpoint M of the segment with the given endpoints. Then find the distance between the two points. R
Mrac [35]

Answer:

Midpoint (-2,4)

distance nearest tenth = 8.9

The approximate distance = 9

Step-by-step explanation:

Formulas

PQ midpoint = (x2 + x1)/2, (y2 + y1)/2

distance d = sqrt( (x2 - x1)^2 + (y2 - y1)^2 )

Givens

x2 = -4

x1 = 0

y2 = 1

y1 = 7

Solution

M(PQ) = (-4+0)/2, (1 + 7)/2

M(PQ) = -2, 4

The midpoint is -2,4

The distance = sqrt( (4 - 0)^2 + (1 + 7)^2 )

The distance = sqrt(16 + 64)

The distance = sqrt(80)

The distance = 4√5           exactly

The distance = 8.94    

The distance = 8.9            To the nearest tenth

Question 2

The distance is rounded to the nearest whole number which is 9.

HELP PLEASE 10 POINTS!!!
7nadin3 [17]

Answer:

First, write 80% as 80100. Then write an equivalent ratio that has the answer in the numerator and 200 in the denominator. 100 x 2 is 200, so 80 x 2 will be the answer. 80 x 2 = 160. The answer is $160.
