GenaCL600 [577]

Angle needs to sell 16 membership cards.

First, I subtracted 72 from 200 and that gave me 128. Then, I divided 128 by 8 and got 16. To check my work I multiplied 16 by 8 and got 128. Then I added 72 to 128 and got 200.

Hope this helps!

Find the area under the standard normal curve to the left of z=1.25.

snow_tiger [21]

For quite some time now, calculators have had statistical functions built in. Here we need to use the stat. function normalcdf, which has only two inputs when we're working with z scores instead of raw scores.

Here,

normalcdf(-100,1.25) = 0.894

This same result could be obtained using a table of z-scores.

Which statement justifies why ∠EBC measures 90°? Given: angles ABD and DBC are complementary

luda_lava [24]

The statement that justifies why ∠EBC measures 90° is that the sum of the measures of two complementary angles is 90 degrees.

<h3>What are complementary angles?</h3>

The complementary angles are angles that when we find their sum it will be equal to 90 degrees and that is why its been regarded as the complementary angles.

We can see that m∠ABD and m∠DBC are complementary, because m∠ABD + m∠DBC=90°

Therefore, The statement that justifies why ∠EBC measures 90° is that the sum of the measures of two complementary angles is 90 degrees.

I need help. please thanks

Answer:

1920

Step-by-step explanation:

What we can do is split this into two sections: the volume of the rectangle and the volume of the square.

Rectangle: We can follow the equation V = lbh, so we have 14x8x10, giving us 1120.

Square: We can use the same equation, V = lbh, giving us 10x10x8 which is 800.

Final Answer: To get the full volume, we have to add these together, so, 1120 + 800 = 1920.
