Find the midpoint of the line segment joining the points (9.7) and (-3,- 7).
The midpoint is

(3,0)

Step-by-step explanation:

The midpoint is found by taking the average of the x points and the average of the y points

x coordinate is (9+-3)/2 = 6/2 = 3

y coordinate is (7+-7)/2 = 0/2 = 0

The midpoint is (3,0)

d. millimeters per hour.

step-by-step explanation:

we are given that,

carlo used a rain gauge to measure the amount of water his lawn is receiving from the sprinklers.

since, according to the options, we see that,

water cannot be measured by 'miles per hour', 'meters per second' and 'grams per seconds'.

we get that, the water can be measured by 'millimeters per hour'.

hence, the appropriate rate for describing the amount of water is 'millimeters per hour'.

36 girls

step-by-step explanation:

the 48 boys is 4 parts of the ratio

divide 48 by 4 to obtain one part of the ratio

= 12 ← 1 part of the ratio

3 parts = 3 × 12 = 36 ← number of girls
