Answer:
1. Choose: 3
2. Choose: 144
3. Choose: 18
Step-by-step explanation:
The first thing you do is multiply 48 * 3/8= 18. Then multiply 48 * 1/8= 6. Then divide both answers to get 3, so 48 * 1/8 * 3.
Then to find the second Choose option, you know that 48 * 1/8 * 3= 18; so 18 * 8= 144(to check your answer, divide 144/8 = 18).
Finally, to find the third Choose option, you divide the fraction 144/8 = 18.
Answer:
5/(1/2)(3.9)(4)² - 2/(2/5)(3.9)(4)² - 1/(3/5)(3.9)(4)² - 1/2(3.9)(4)²
Convert mixed numbers to improper fractions,
11/2(3.9)(4)² - 12/45(3.9)(4)² - 8/5(3.9)(4)² - 1/2(3.9)(4)²
Remove bracket,
11/2 × 3.9 × 4² - 12/45 × 3.9 × 4² - 8/5 × 3.9 × 4² - 1/2 × 3.9 × 4²
Factor out common term 3.9 × 4²,
3.9 × 4² (11/2 - 12/5 - 8/5 - 1/2)
Times,
3.9 × 16
Answer,
62.4

Y=7,450,349(1-.0089)^10
Answer:
subtract 3.97 from 25.32 and that how much he got a profit of
Step-by-step explanation:
however much he prices it up by is the profit
Let the second angle = X
The first angle = 2X+42 ( 42 more than 2 times the second angle)
Now you have 2x+42 + x = 90 ( first angle + second angle = 90)
2x + x = 3x
Now you have:
3x +42 = 90
Subtract 42 from both sides:
3x = 48
Divide both sides by 3:
x= 48/3
x = 16
The second angle = 16 degrees.
The first angle = 2(16) + 42 = 32+42 = 74 degrees
