Answer: 38 in.^{2}
Step-by-step explanation:
1/ Find the area of the triangular sides. (1/2 x 2 x 6 = 
for each triangular side)
2/ Find the area of each of the rectangular sides. In this case, the bottom (base) side is 2x6 = 
. The rectangular side on the left is 2x3 = , and the rectangular side on the right is 4x2 = 
.
3/ Add everything together. Rectangular Sides + Triangular Sides = Surface Area ---> 
4/ You have your answer, now hope it helps ! :)
Answer:
50%
Step-by-step explanation:
He sold it for Rs 15 each. What is his profit percent? CP of 1 pen = 120/12= 10 SP of 1 pen = 15 Profit = 5 P % = (p/CP)*100=(5/10) x 100 = 50%.
Total investment = $10,500
Let x = amount of first investment, and y the amount of the second investment.
First investment:
Interest rate = 9 (1/5)% = 0.092
Earned interest = 0.092x
Second investment:
Interest rate = 9% = 0.09
Earned interest = 0.09y
Total interest after one year is $957.00, therefore
0.092x + 0.09y = 957
or
1.0222x + y = 10633.33 (1)
Also,
x + y = 10500 (2)
Subtract (2) from (1).
0.0222x = 133.33
x = 6000
y = 10500 - x = 4500
Answer:
The first investment is $6,000 at 9 (1/5)% rate;
The second investment is $4,500 at 9% rate.
<u>Answer</u>
12
<u>Explanation</u>
Cosine is the ratio of adjacent to hypotenuse.
So, in this case b is the adjacent and 13 is the hypotenuse.
cos22.6 = b/13
b = 13×cos22.6
= 13×0.923879532
=12.010
To the nearest whole number the answer is 12.
