In the figure, angle D measures 31⁰ and angle A measures 27⁰
Zielflug [23.3K]

Answer:

1)B:63°

2)A:59°

Step-by-step explanation:

1.ABC is a right triangle at C then angle ACB=90°(right angle)

Angle CAB=27°(see the given)

measure of the angles in any triangle is 180°

then angle CBA=

measure of all the angles - (measure ACB+measure CAB)

=180°-(90°+27°)

=63°

2. Same explanation of angle B:

in the right triangle DEF: angle DEF=90°

angle D=31°(given)

Then measure of angle A=180°-(angle E + angle D)

=180-(90+31)=59°

A track coach is trying to improve the 50 -meter-dash times of the track team. He times each student and then implements a month
Aleks04 [339]

Answer:

-5

Step-by-step explanation:

Given the two box plots showing the number of seconds the students completes the 50-meter-dash race before and after the program, we are to determine the difference between the median value of seconds before and after the program.

Median in a box plot is represented by the vertical line that divides the rectangular box in a box plot.

Thus, the median before the program = 15 seconds

The Median after the program = 10 seconds

The median change = 10 - 15 = -5 seconds.

This means, after the program, most of the students now finish the 50-meter-dash faster, about 5 seconds less the former seconds used before the program.

You deposit 700$ in an account with an annual internet rate of 4% after 5 years
alex41 [277]

Answer:

840

Step-by-step explanation:

Heres the easiest way to figure this out. You deposit $700 dollars into your account, correct? So, the annual interest rate is 4%. Take 700 dollars and multiply that by 4 percent. You get $28. So, EVERY. SINGLE. YEAR. you get 28$. So, multiply 28 by 5. Thats $140. Then, add 140 into 700, and you get 840.

Hope this helped!

During a certain period in life of an earthworm it's length L cm is directly proportional to the squareroot of N where N is the
Ierofanga [76]
<h2>Answer:</h2><h2>The equation connecting L and N is L = 2.5 √N</h2>

Step-by-step explanation:

Given, during a certain period in life of an earthworm it's length L cm is directly proportional to the squareroot of N

Let L be the length of the earthworm,

N be the number of hours after its birth one hour after an earthworm is born  

The equation conecting L and N is,

L = k√N  where k is a constant whose value we can find using the given information:

When N = 1, L = 2.5

2.5 = k√1

k = 2.5

Therefore L = 2.5 √N
