Answer:
64 feet
Step-by-step explanation:
To find the height of the kite we use sin trigonometric ratio.
Let the height of the kite from the ground be x feet.
![\therefore \: \sin 40 \degree = \frac{x}{100} \\ \\ \therefore \: 0.6427876097= \frac{x}{100} \\ \\ \therefore \: 0.6427876097 \times 100= x \\ \\ \therefore \:x = 64.29 \\ \\ \therefore \:x = 64 \: feet](https://tex.z-dn.net/?f=%20%20%20%5Ctherefore%20%5C%3A%20%5Csin%2040%20%5Cdegree%20%3D%20%20%5Cfrac%7Bx%7D%7B100%7D%20%20%5C%5C%20%20%5C%5C%20%20%5Ctherefore%20%5C%3A%200.6427876097%3D%20%20%5Cfrac%7Bx%7D%7B100%7D%20%20%5C%5C%20%20%5C%5C%20%5Ctherefore%20%5C%3A%200.6427876097%20%5Ctimes%20100%3D%20x%20%5C%5C%20%20%5C%5C%20%20%5Ctherefore%20%5C%3Ax%20%3D%2064.29%20%20%5C%5C%20%20%5C%5C%20%20%5Ctherefore%20%5C%3Ax%20%3D%2064%20%5C%3A%20feet)
Answer:
3.05 or 31/2 pounds
56 ounces
Step-by-step explanation:
To find the total weight all the weights have to have the same units of measurements
It is either pounds is converted to ounces or ounces is converted to pounds
1. convert ounces to pound
1 ounce = 0.0625
12 ounces = 0.0625 x 12 = 0.75 pounds or 3/4
add together = 1 1/2 + 3/4 + 1 1/4 = ![1\frac{1}{2} + \frac{3}{4} + 1\frac{1}{4}](https://tex.z-dn.net/?f=1%5Cfrac%7B1%7D%7B2%7D%20%2B%20%5Cfrac%7B3%7D%7B4%7D%20%20%2B%201%5Cfrac%7B1%7D%7B4%7D)
=
= 3 1/2
2. 16 ounces = 1 pound
flour = 16 x 1 1/2 = 24
sugar = 16 x 1 1/4 = 20
total = 24 + 20 + 12 = 56 ounces
25-4x=16-4x
25-4x+4x=16-4x+4x
25=16
