Answer:

The answer is each piece will weigh 1/8 of a pound.

Step-by-step explanation:

If she has 3/8 pounds of chocolate and cuts it into 3 pieces we will divide the total amount (or in this case weight) of the chocolate by 3 in order to get our answer. By taking 3/8 and splitting it into 3 equal pieces we are left with 3 pieces each weighing 1/8 of a pound. You can verify this is correct by multiplying 1/8 by 3 to get 3/8

Marie purchased a 29.00 gift. She uses a coupon that offers 30 percent. How much will she spend on the gift after the coupon?
asambeis [7]

Answer:

$20.30

Step-by-step explanation:

The usual price of the gift is $29.00

Marie will get 30% DISCOUNT on this price if she uses her coupon. So, the final price would be 30% less than $29.00

First, we need to find 30% of $29.00. Then we need to subtract that from original price (29).

Convert percentage to decimal first:

30% = 30/100 = 0.3

Now multiply this with 29 to get:

0.3 * 29 = $8.70

We subtract this from original price to get DISCOUNTED PRICE:

$29.00 - $8.70 = $20.30

A 25 foot ladder is leaning against a house. If the angle of Elevation of the ladder is 72 degrees:
coldgirl [10]

Answer:

1. 23.8

2. 7.7

Step-by-step explanation:

<u>for the first blank</u>

use sin because x is opposite and 25 is hypotenuse

set up an equation:

sin(72)= (x/25)

multiply both sides by 25:

25(sin(72))= (x/25)25

25(sin(72))= x

multiply 25 by sin(72):

23.8 = x

<u>for the second blank</u>

use cos because x is adjacent and 25 us hypotenuse

set up an equation:

cos(72)= (x/25)

multiply both sides by 25:

25(cos(72))= (x/25)25

25(cos(72))= x

multiply 25 by cos(72):

7.7= x
