Explanation:If the bank has only quarters and dimes, and its total amount of coins is 250, then be x the amount of quarters it has, it will have 250−x dimes.
A quarter is worth 0.25$, a dime is worth 0.10$ and the 250 coins together are worth 39.25$.
Answer:
No, he won't
Step-by-step explanation:
Given
Target = 480 pages in 28 days
Rate = 60 pages in 4 days
Required:
Determine if he'll reach his target
The rate can be expressed using:
So, we have:
Multiply the fraction by
This can be interpreted as: 420 pages in 28 days
And his target is 480 pages in 28 days
<em>Hence, he wont finish the book at that rate</em>
Answer: 123.5 in^2
Step-by-step explanation: The formula for the area of a trapezoid is a+b/2 x h. In other words, base 1 plus base 2 divided by 2, and multiplied by the height. Plug in the numbers. The equation is:
6+7/2 x 19 = 123.5.
Since you are finding the area, the answer would be in inches squared. The answer is 123.5 in^2.
Answer:
A) 99.5%
B) 42.1%
Step-by-step explanation:
A) Since the probability of 3 sixes is 0.5%, the probability of less than 3 sixes (that is, zero, one, or two sixes) is 100% - 0.5%, or 99.5%
B ) Since the probability of no sixes is 57.9%, the probability of at least 1 six is 100% - 57.9%, or 42.1%
