Answer:

37.5

Step-by-step explanation:

If you cut 600 in half 4 times the first time it will be 300 because 600/2 is 300. The second time it will be 150 because 300/2 is 150. The third time it will be 75 because 150/2 is 75. The fourth time it will be 37.5 because 75/2 is 37.5, so that is the answer.

If this helps please give me brainliest. Thx :)

Answer:

(x, y, z) ≈ (30.375, 12.369, 13.915)

Step-by-step explanation:

You can make use of the fact that all of these right triangles are similar. That mean the ratio of the hypotenuse to the long side is the same for each of them.

27/24 = x/27

x = 27²/24 = 30.375 . . . . . . multiply by 27

Likewise, the ratio of short side to long side is the same for each:

y/24 = (30.375 -24)/y

y² = 24(6.375)

y = √153 ≈ 12.369

And the ratio of short side to hypotenuse is the same:

z/30.375 = 6.375/z

z² = 30.375×6.375 = 193.640625

z = √193.640625 ≈ 13.915

The distance AB= [?] Round to the nearest tenth.

Law Incorporation [45]

Answer:

<h3>Step-by-step explanation:</h3>

A = ( -2, 1 )

B = ( 1, -1 )

$\boxed{\bf x_1 : - 2}$ $\boxed{\bf x_2 : 1}$

$\boxed{\bf y_1 : 1}$ $\boxed{\bf y_2 : - 1}$

______________________________

$\sf d = \sqrt{(x_2 -x_1) ^{2} + ( y_2 - y_1) ^{2} }$
$\sf d = \sqrt{(1 - ( - 2)) ^{2} + ( - 1 - 1) ^{2} }$
$\sf d = \sqrt{ {3}^{2} + {( - 2)}^{2} }$
$\sf d = \sqrt{(9 + 4)}$
$\sf d = \sqrt{13}$
$\sf d = 3.6$

a caterer received an order to prepare 120 servings of salad for a banquet. Each serving will weigh 4 ounces. so far the caterer

Ugo [173]

To easier digest this question, we can multiply the 120 servings by 4 ounces to make it into a common unit of measurement. This way, we can compare ounces with ounces instead of ounces to servings.
We then have 480 servings, and the poor caterer only has 60 ounces. We can put that into a fraction, 60/480. From here, things get slightly easier. All we have to do is make it into a fraction we can digest, which would be 1/8. We can turn that fraction into a decimal by simply dividing. We have 0.125.
Since we are changing from a decimal into a percent, we have to move the decimal point two places to the right. We have out final answer of 12.5%.
