Find the coordinates of the midpoint of AS if A(-4, 7) and S(5,3).
lesya692 [45]

Answer:

The answer is

<h2>( \frac{1}{2}  \: ,  \: 5)</h2>

Step-by-step explanation:

The midpoint M of two endpoints of a line segment can be found by using the formula

<h3>M = (  \frac{x1 + x2}{2} , \:  \frac{y1 + y2}{2} )</h3>

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

A(-4, 7) and S(5,3)

The midpoint is

<h3>M  = ( \frac{ - 4 + 5}{2} , \:  \frac{7 + 3}{2} ) \\  = ( \frac{1}{2} , \:  \frac{10}{2} )</h3>

We have the final answer as

<h3>( \frac{1}{2}  \: ,  \: 5)</h3>

Hope this helps you

Which of the following statements is not true of scientific experiments? Which of the following statements is not true of scient
Alenkinab [10]

Answer:

The false statement is: They must occur under carefully controlled conditions found in a laboratory.

Step-by-step explanation:

Scientific experiments do not always occur in laboratories, also, in the case of social studies, the experiments are done under not controlled conditions to prove the hypothesis.

On the other hand, all scientific experiments must be well documented and they always give useful results (in case the hypothesis is rejected, future investigations will use other hypothesis).

An outdoor spigot at the school has a leak and is dripping water. A student counted eighty drops of water in five minutes and no
lianna [129]

Answer:

D. 108 liters

Step-by-step explanation:

Given that the leak is ;

5 drops = 5 minutes

?= 4 weeks

Find number of hours in 4 weeks

1 week=7days

4 weeks=?--------------cross multiply

4×7=28 days

1 day=24 hours

28 days=?--------------cross multiply

28×24=672 hours

Hour= 60 minutes

672 hours=?

672×60=40320 minutes

Finding the leakage in 4 weeks

80 drops= 5 minutes

?=40320 minutes------------cross multiplication

(40320×80)÷5 =645120 drops

Finding the liters of water wasted in 4 weeks

60 drops of water= 10 milliliters

645120 drops of water=?-------------cross multiply

(645120×10)÷60 =107520 milliliters

But you know

1 milliliter=0.001 liters

107520 milliliters=?-----------cross multiply

107520×0.001

=107.52 liters

=108 liters

Anika [276]

Answer:

16.67%

Step-by-step explanation:

Total main course dishes sold during the day = 240

Burritos = 40

what percent of the main course dishes sold were burritos

Percentage of burritos sold = number of burritos sold / total number of dishes sold × 100

= 40/240 × 100

= 0.1666666666666 × 100

= 16.666666666666%

Approximately 16.67%
