Answer:
10 square in.
Step-by-step explanation:
The rectangles are similar by a scale factor of 3. We can tell because the quotient of two of the corresponding sides, 18 and 6, is 3 (18/6=3)
That means the width of ABCD is 3 times the width of WXYZ.
Let's say the width of ABCD is x. Then 18*x=90 because that's the area.
x=90/18=5
Now we have the width of ABCD, 5, so to get the width of WXYZ, we divide by 3, which is 5/3.
Now to get the area of WXYZ, we can do 5/3, the width, times 6, the length, which is 30/3=10.
Answer:
The answer is 21 1/3
Step-by-step explanation:
First you have to take 5/9 and subtract it by 1/5 and you will get 16/45. Then you multiply 60 times 16/45 and get 21 1/3
85÷(9×5)-(10×4)
85÷(45)-(40)
85/5
17
I think I did this right....
Answer:
Step-by-step explanation:
2p = 6 x 4 = 24 in
lateral surface (par) = 24 x 6 = 144 in^2
lateral surface (pyramid) = (24 x 4) / 2 = 48 in^2
lateral surface (total) = 144 + 48 = 192 in^2
10% maybe I think. Not completely sure tbh.
