Answer
Find out the length of the second parallel side.
To prove
Formula
Where a , b are the parallel sides of trapezoid and h is the height of the trapezoid.
As given
The area of a trapezoid is 132 cm².
The height is 12cm and the length of one of the parallel sides is 9cm.
Here h = 12cm
a = 9cm
Put in the formula
132 × 2 = 9 × 12 + 12b
264 = 108 + 12b
264 - 108 = 12b
156 = 12b
b = 13cm
Therefore the length of the second parallel side is 13cm.
So, Bob needs 2 cups of concentrate (I'll use the variable c to shorten it) for every 3.5 cups of water (w). When he has 6 cups of c, he has three times the original recipe, and therefore we need 3w as well.
3.5x2=6+1=7. So we need 7 cups of water.
Now, 6 cups of concentrate + 7 cups of water = 13 cups of orange juice.
Bob can make 13 cups of orange juice.

Answer:
The bullet point between the numbers means times in this case, in some other cases it would mean "and" also known as plus. Therefore, the correct answer is the second one.
Step-by-step explanation:
In each half unit cube there is 6 cubes. ⇒
6 + 6 + 6 = 18 ⇒
But, this is not one of the options.⇒
So, we have to make the equation a bit different to solve it. ⇒
2 x 3 x 2, is the first option. ⇒
This is incorrect, as it equals 12. ⇒
The sum we are looking for is 18. ⇒
The second answer is 2 x 3 x 3. ⇒
This equals 18, we have found the correct answer. ⇒
So, there are a total of 3 half-unit cubes. ⇒
There are a total of 18 cubes. ⇒
I hope this helps!
Answer:
it would be a and d
Step-by-step explanation:
so you start from zero for a and it says its 60 dollars more then they thought it would be so it would be
for b
