Answer:
The percentage rate per annum is 2.8%
Step-by-step explanation:
We need to multiply the principal by the time, then divide the interest by the product of P×T, so:
1,600 × 5 = 8,000
224 ÷ 8,000 = 0.028
Then we convert our final product to a percentage.
0.028 to a percent is 2.8%
You would have to add 47.50 + 122 to get 169.5 dollars. to get the amount of money he made in the summer, you would have to multiply 169.5 by 2 which would equal 339 dollars. so he made 339 dollars over the summer :)
Since this is a right triangle, you can use the main trig functions sin, cos, and tan. We must use sin for this problem because sin= opp/hyp. Plug in the numbers to this function. Sin (53) = a/25. Thus when you cross multiply, you get a= sin (53) x 25. When you plug it into a calculator the answer should come out to 19.97
Answer:
The solution is (0, 2).
Step-by-step explanation:
Here we have two different equations for y. Equate them to eliminate y. Solve the resulting equation for x:
y = −1/3x + 2 = y = x + 2
Simplifying, we get (-1/3)x = x, and so x must be 0.
Then, using the second equation, we find that y = 0 + 2 = 2.
The solution is (0, 2).
1: = 12x-39
2 = -11d+44
3 = 20y-15
4 = -22
5 = -4m+4
6 = 13h+21
7 = -6g+3
8= 13c-20
9 = -2q+12
your welcome cutie ;)
