400 --- 100%
60 --- x%
x = 60/400 * 100 = 15% <span>chocolate.</span>
<span>What we are asked to find out is speed per hour. To find speed, divide distance by time. Distance is 3000 ft and time is 1 3/4 hr. To make calculations easier, let us convert time into minutes. 1 hour is 60 minutes and 3/4 hour is 45 minutes. So total minutes is 105. Now let us divide 3000 by 105. We get 28.57 ft per minute.
Now multiply this number by 60 to convert speed per minute into speed per hour.
28.57 * 60 = 1714 ft in 1 hour.</span>
Answer:
29*sqrt(5)
Step-by-step explanation:
Start with sqrt (45). You must reduce it to it's prime factors.
45: 9 * 5 9 is not prime so reduce it.
45: 3 * 3 * 5
When you write √45, you should replace it with √(3*3*5)
The rule is
Rule: when you have a pair of equal prime factors under a root sign, you can take one out and throw one away.
Rule 2: If there are an odd number of equal primes one of them will be left underneath the root sign.
√45 = 3√5
11sqrt(45) - 4 sqrt(5) Substitute for 45
11*3*sqrt(5) - 4sqrt(5) Take out sqrt(5) using the distributive property.
(11*3 - 4)*sqrt(5) Combine 11 * 3
(33- 4) * sqrt(5) Do the subtraction
29 * sqrt(5) Answer
Answer:
pages
Step-by-step explanation:
Method 1: Working with minutes
Let us assume that, Sandra's printer can print x pages in 1 minute.
Then we can write the equation:
We can rewrite the ratios as a fraction.
This simplifies to
Or
Method 2: Working with seconds
If 5 pages corresponds to 40 seconds, then we can write: 
Let y corresponds to 60 seconds (1 minutes).
Then:
We rewrite as fraction:
Multiply both sides by:
Abscissa is the other term of x axis and ordinate is the other term for y axis. The product is defined as the answer from numbers that are multiplied. Since it is said that the numbers are multiplied, therefore x is multiplied by y to get the product which is ten. So the correct answer that would represent the given statement above is option A. xy= 10. Hope that helps!
