Answer: 37.5%
Explanation:
Percentage is defined as parts of an amount in 100 parts of a basis. This must be stated mathamatically for better understanding and for calculations. It is the ratio:
% = (parts / base) × 100.
In this case you need to express the amount of butter as a part in 100 parts of all purpose flour, which, using the above definition, is:
% butter = (0.75 pounds of butter / 2 pound of flour) × 100
% butter = 0.75 × 100 / 2 = 75 / 2 = 37.5
The answer is expressed as 37.5%.
The number of full periods and classes does a 202-digit number have are 1 and 3 respectively.
<h3>What are periods?</h3>
Periods are simply groups of three digits separated by commas when writing numbers in standard form.
The digit number, 202 has 1 period.
Classes is simply the number of digits in a set.
Example: 500 has 3 classes
We can say that the 202 digit number has 1 period and three classes.
Thus, the number of full periods and classes does a 202-digit number have are 1 and 3 respectively.

x ÷ y = 29/30_____
A suitable calculator can do this for you.
Answer: -1/2
You get y = 2x - 5, so the slope is 2. Perpendicular lines have opposite-reciprocal slopes, so the slope of the line we want to find is -1/2.
Answer:
Step-by-step explanation:
The rate of change in any function is the slope of the line between 2 points. Our points are t = 2 and t = 5. But we know that the slope formula also involves the h's for each of those t's. We need to find them first. The slope formula is
, but for us it will look like this (fittted to our needs):
. So we need to find those h's.
when t = 2, plug in a 2 for t and solve for h.
Therefore, 
and
h(2) = 32 and in coordinate form, (2, 32).
When t = 5, plug in a 5 for t and solve for h.
Therefore, 
and
h(5) = 14 and in coordinate form, (5, 14). Now we can plug into our slope formula:
, choice B.
The rate of change is -6 which, in words, means that the ball fell 6 feet every 1 second it fell.
