It would be the 3rd choice I think
- Principle=P=470
- Time=T=10
- Rate =R=R=9%
Interest be I
If interest is daily
- I=PRT/100
- I=470(10)(9)/100
- I=4230/10
- I=423$
If interest is monthly (30days)
- I=(470)(1/3)(9)/100
- I=470(3)/100
- I=1410/100
- I=14.10$
Answer:
21 dollars each
Step-by-step explanation:
35 dollars to mow the lawn
20% tip means he will actually get the 35 dollars and whatever 20% of 35 is...
35+.2(35)
35+7
42
But he is mowing with a buddy, so he is going to split this around between him and his buddy. So 42/2=21.
They will get 21 dollars each.
Answer:
61.5
Step-by-step explanation:
In this case to calculate the height, we do the following:
The first is the graphic, attached image.
Then the calculations.
b / d = tan (42 °) = 0.9
d = b / 0.9
Then we have to:
(40 + b) / d = tan (56 °) = 1.48
(40 + b) = d * 1.48
Replacing we have:
(40 + b) = (b / 0.9) * 1.48
40 + b = 1.65 * b
1.65 * b - b = 40
b = 40 / 0.65
b = 61.5
Therefore the height is approximately 61.5
Step-by-step explanation:
5x + 4y = 25
−(5x + 2y = 3)
2y = 22
