Answer:
The answer is that her mom will donate $2.
Step-by-step explanation:
From the information given, you can use a rule of three to find the amount her mom will donate if Emily bikes 15 miles given that her mother pledges 10 cents for every 0.75 miles:
0.75 miles → 0.10
15 miles → x
x=(15*0.10)/0.75
x= 2
According to this, the answer is that her mom will donate $2.
Answer:
Spine length = 48 cm
Step-by-step explanation:
So the little marks at the top of the kite closely resemble the "right angle" symbol, but it's a trick
The top angle can be found using the law of cosines
78² = 62² + 62² - 2(62)(62)cosθ
78² = 2(62²) - 2(62²)cosθ
cosθ = (78² - 2(62²)) / -2(62²)
cosθ = 0.2086...
θ = 77.9575...°
Spine = 62cos(77.9575 / 2)
Spine = 48.1975...
