Answer:
333.333
Step-by-step explanation:
2000 devided by 6=333.333
There are 9 two-year-olds and 18 each of 3 and 4 year olds.
To solve this we could write and solve the equation below, letting x be the number of 3 and 4 year olds.
x/2 + x + x = 45
x + 2x + 2x = 90
5x = 90
x = 18
From here, we just divide 18 by 2 to get the number of 2 year olds.
The bicycle with a 30-inches diameter rolls approximately 28.8 more than a tire with the diameter with 21-inches.
<u><em>How to solve:</em></u>
- First use the formula: C = 3.14d
- Replace the d value with 30 and solve the equation:
C = 3.14 x 30 ⇒ 94.2477796077
- Then solve the equation again but 21 as the d value:
C = 3.14 x 21 ⇒ 65.9734457254
- Then subtract 65.9734457254 from 94.2477796077 to get the approx. answer of 28.8
7% Of 9000 is 630. Then subtract 630 from 9000. So your answer becomes 8370.
x=16
Explanation
the ratio is 2:3
it means for every 2 cars, there are 3 trucks
Now, it the total of trucks is 24,the proportion must be the same, so
Step 1
Let
x represents the number of cars for 24 trucks

Step 2
solve for x

Hence, the answer is 16
