76.5% would be if we round to the nearest tenth
Answer: you would just do y= 4x (4•1 would be 4) plus 7. hope this helps!!
Step-by-step explanation:
Answer:
C.) 21
Step-by-step explanation:
d = 22.5n + 27.5
Where d is the total amount of money earned and n is the number of items sold
Substitute:
500 = 22.5n + 27.5
We can substitute 500 for d because 500 is the total amount of money Kathryn wants to earn
Solve:
500 = 22.5n + 27.5
Subtract 27.5 on both sides:
500 = 22.5n + 27.5
-27.5 -27.5
472.5 = 22.5n
Divide by 22.5 on both sides:
472.5 = 22.5n
/22.5 /22.5
21 = n
Therefore, Kathryn must sell 21 items to make $500.
Answer:
16.5km
Step-by-step explanation:
Liola drives 17km up a hill that is at a grade of 14 degrees. What horizontal distance, to the nearest tenth of kilometer, has she covered?
We solve using Trigonometric function of Cosine
cos theta = Adjacent/Hypotenuse
Theta = 14°
Hypotenuse = Distance up the hill = 17km
Adjacent = Horizontal distance = x
Hence,
cos 14 = x/17
Cross Multiply
x = cos 14 × 17
x = 16.495027347km
Approximately = 16.5km
The horizontal distance = 16.5km
