Answer:
The surface area of the composite figure is 
Step-by-step explanation:
we know that
The surface area of the composite figure is equal to the surface area of the rectangular prism of the bottom plus the lateral area o the rectangular prism of the top
so
Step 1
Find the surface area of the rectangular prism of the bottom
The surface area is equal to
Find the area of the base B
substitute
Step 2
Find the lateral area of the rectangular prism of the top
The lateral area is equal to
substitute
Step 3
Find the surface area of the composite figure
If the 5 of them weigh 1/4 of a ton
then 1 of them weigh x
5/1 = 1/4//x Do you see what happens? Just by writing down the givens you get a proportion. It will work better for you if you change the 1/4 to 0.25
5/1 = 0.25/x Now it looks like an ordinary proportion. Cross multiply
5x = 0.25*1 divide by 5
x = 0.25/5
x = 0.05 tons. We better change this to pounds.
1 ton = 2000 pounds
0.05 ton = x
1/0.05 = 2000/x Cross multiply
x = 2000 * 0.05
x = 100 pounds.
Answer:
3
Step-by-step explanation:
P+r-2
=3+2-2
=5-2
=3 is the answer.........................
Doesn't make sense, it's a 48 degree angle if that helps.
We know that 7/10 of the cookies are chocolate chip, so that means there are 3/10 of the cookies left.
We now want to find what 3/4 of 3/10 is.
We can do this by multiplying both fractions
3/4x3/10 (we just multiply across) to get 9/40.
We cannot simplify this answer, so our final answer is 9/40 of the cookies are sugar cookies.
