Answer:
700$ at 2% 800$ at 4%
Step-by-step explanation:
x+y=1500 This is because the total is 1500 dollars into 2 different accounts, x and y.
0.02x+0.04y=44 This is because it says 2 percent interest in one account and 4 percent in the other, and the totals add up to 44 dollars.
Now use elimination method.
x+y=1500(-0.02)=-0.02x+-0.02y=-30
0.02x+0.04y=44
Now you end up with 0.02y=14, solve for y and you get 700. That's the value of y which now you can then subtract from 1500 and get 800 which is the value of x.
Answer:Area of wall =

ft
Explanation:First, we know that:1 in = 1/12 ft
Therefore, the dimensions of the wall would be as follows:H = 7 ft 10 in =

ft
B1 = 10 ft 2 in =

ft
B2 = 14 ft 1 in =

ft
For the trapezium, area can be calculated using the following the following formula:Area of trapezium = Average base * height =

* height
Substitute with the given to get the area as follows:Area of wall = ([

+

] / 2) *

Area of wall =

ft
