Find the midpoint of the segment from point a (6,3) to point B (8,1)

velikii [3]

Answer: $M=(7,2)$

Step-by-step explanation:

You need to use the following formula:

$M=(\frac{x_A+x_B}{2},\frac{y_A+y_B}{2})$

Given the points A(6,3) and B(8,1), you can identify that:

$x_A=6\\x_B=8\\y_A=3\\y_B=1$

Now, you can substitute these values into the formula $M=(\frac{x_A+x_B}{2},\frac{y_A+y_B}{2})$ .

Therefore, you get this result:

$M=(\frac{6+8}{2},\frac{3+1}{2})$

$M=(7,2)$

Alexa is researching a cure for the coronavirus. She needs 14 test tubes for 4 experiments. The first experiment requires 2 test

grigory [225]

Answer:

She used 4 test tubes for the last experiment

Step-by-step explanation:

Total test tubes needed = 14

Experiment 1 = 2 test tubes

Total test tubes remaining = total - used

= 14 - 2

= 12 test tubes

Remaining experiment = 4 - 1

= 3

Test tubes used for the remaining experiment = test tubes remaining / Experiment remaining

= 12 / 3

= 4 test tubes

How many test tubes did she use for the last experiment?

She used 4 test tubes for the last experiment
