Answer:
Step-by-step explanation:
Find the amount of time it takes for a beam of light from the Sun to reach Earth.
40%= 0.40 if you think of the decimal being at the end of the number (40.%) than just move the decimal twice makes it 0.40
Answer: 40 mi/h
Step-by-step explanation:
it goes up 80 and over 2, so the rate of change is 80/2 = 40 mi/h
Answer: 4.4
Step-by-step explanation:
First you need to take 4 from both sides and then your left with 5x=22
Then you divide from both sides and you get 4.4.
That is your final answer.
For proportionality constant problems, set up the equation as,
,
Where x and y are the two variables you are comparing and <em>K </em>is the proportionality constant. If we take <em>Caramel Corn </em>values as x and <em>Cheddar Corn </em>values as y, and then solve for <em>K </em>for each ratio lines, we will get the same answer. Let's check.
,
, and
.
Hence, the proportionality constant, in this case <em>K,</em> is equal to
or 1.5. First answer choice is correct.
ANSWER: 1.5
