I’m not sure how to type this but here’s the answer! Have a good day
Answer:
The answer is 40 sq. units
That is: 1/2×b×h (formula for area of triangle)
1/2×10×8
= 40
I think the answere is A.2
Answer:
a. 
b. 
Step-by-step explanation:
I attach the diagram of the new water tank.
a. In order to find the volume of the tank in cubic feet, we will need to calculate the volume of a cylinder. We know that its base measures
and its height is
.
The volume ''V'' of a cylinder is :

Where ''
'' is the diameter of the base and ''
'' is the height of the cylinder.
If we replace all the data in the equation :

We found out that the volume of the tank in cubic feet is 
b. We know that 1 cubic foot of water is equal to 7.5 gallons. To find the amount of gallons that the new tank can hold, we need to do an unit conversion.
This equivalence is given to us :
⇒ Using the equivalence ⇒

Finally, the new tank will hold
of water.
Answer:
5.4 inches
Step-by-step explanation:
This is all about ratios proportions and similarity.
First the 8.5 stays the same you scale only the 11 down to 7
because it says to scale length down to 7
so once you scale it down you should get 5.4 inches for the width once you plug it back in
