Answer:
v=50
Step-by-step explanation:
use the formula V=A(h/3), where V is the volume and A is the area of the base. a=5 h=6 5×6=30 5×3=15 30+15=45 45 rounded to neared whole number which is 50
Answer:
$6981
Step-by-step explanation:
Let's find the answer by using the following formula:
(this year cost)=(last year cost)+((last year cost)*(percent increase of cost)) so:
3750+3650=X+0.06X where X=last year cost, then:
7400=1.06X
6981.13=X
In conclusion, last year he spent $6981.
Answer:
Step-by-step explanation:
this is a similar triangle, so the side that is 6 and 18 will have the same ratio as the side 4 and x, then
6/18 = 4 / x
x = 4 * 18/6
x = 2 * 18 / 3
x = 36 /3
x = 12

Answer:
20 feet
Step-by-step explanation:
The scale is 3 inches is to 2 feet
As a ratio, it would be:
The question is what is the actual length of the stage if the drawing is 30 inches. All we need to do is find a ratio proportional to the scale ratio:
Now to find the missing number, cross multiply the fractions first:
Then solve for x:
The answer is 20 feet
Answer:
21
Step-by-step explanation:
The denominators are 3 and 7 and those are both odd numbers.
You can not get a number lower than 21. Therefore 21 is the LCM (Lowest common denominator.)
Hope this helps :)
