Answer:
2x+30 = 90
Step-by-step explanation:
The two angles are complementary so they add to 90 degrees
2x+30 = 90
Hey the answer is 4000 ft^3 , choice c
Answer:
1)option b
2)option a
Step-by-step explanation:
1) circumference = 62.8 in
=> 2πr= 62.8
=> r= 62.8/(2×3.14)= 10 in
diameter = 2×10 in = 20 in
2)diameter = 14m
radius = 7 m
Area of the circle= πr² =3.14(7)²=3.14×49
= 153.86
=153.9 m²
Since the songs are $1 each and the audio books are $4 so for every ONE audio book he buys at $4, he will buy THREE songs at $1 each. So if he buys 5 audio books he will buy 15 songs and in turn spend $20 on audio books and $15 on songs. You can make a formula to solve this problem if S= amount of songs and A= amount of audio books
S=A*3 input the number of Audio books and you get the number of songs per audio book. For example S=5*3 S=15 so you have 15 songs when you buy 5 audio books.
In order to calculate price (Total price = T), T=S+(A*4) This can only be calculated once you do the first formula. So since A=5 and S=15
T=15+(5*4) T=$35 If Ben buys 5 Audio Books and 15 songs, he will spend $35
Using the formula, Ben can buy 6 Audio books and 16 songs and spend $40
So Ben's options are either spending $35 and having 3 times as many songs as he does Audio books
Or spending all of his $40 and buying 1 more of each
(Additionally, he could buy 5 more songs and spend the same amount of money)
Multiply each side by 6 to get rid of the fraction. 96/2 = 48
