Answer:
I think it's either Wednesday or Sunday.
Step-by-step explanation:
This question is an example of d = r * t
r = rate
r = 3*10^8 m/s
t = ??
d = 7.5 * 10^6 meters.
Sub and solve
d = r * t
7.5 * 10^6 = 3 * 10^8 * t Divide both sides by 3 * 10^8
7.5 * 10^6 / (3 * 10^8) = t
2.5 * 10^(6 - 8) = t
2.5 * 10^-2 seconds = t or
0.025 seconds = t
Answer:
The markup (in percentage) is 66.67%
<em>The markup (in dollars) is $33.92</em>
Step-by-step explanation:
First, we will find the sales price of the product (excluding sales tax).
Let sales price be "x", so we can say:
x increased by 6.25% is 90.10
<u>Note: </u> 6.25/100 = 0.0625
Thus, we can write an equation and solve for x now:
The markup is a percentage of the cost.
The markup is the difference in cost and sales price, divided by cost. Then we multiply by 100 to get percentage. So:
MarkUp = 
The markup (in percentage) is 66.67%
In dollars, it will be $33.92
The total lemonade the two friends bring to the cookout when one brings 2.7 liters and the other brings 3.54 liters of lemonade is 6.24 liters of lemonade, computed using decimal addition.
The methods we use to add or subtract decimals are as follows:
- Vertically align the decimal points. Any necessary zeros should be entered.
- Treat the integers as whole numbers when adding or subtracting them.
- Align the decimal point with the numbers being added or subtracted so that it sits vertically above the sum or difference.
In the question, we are informed that two friends bring lemonade to the cookout. The first brings 2.7 liters and the second brings 3.54 liters.
We are asked to find the total lemonade brought by them to the cookout.
To find the total lemonade, we add both the decimal quantities following the steps discussed.
2.7
+ 3. 54
Step 1: Adding zeroes:
2.70
+ 3. 54
Step 2: Treating them as numbers and adding:
2.70
+ 3. 54
________
624
Step 3: Aligning decimal points:
2.70
+ 3. 54
________
6.24
Thus, the total lemonade the two friends bring to the cookout when one brings 2.7 liters and the other brings 3.54 liters of lemonade is 6.24 liters of lemonade, computed using decimal addition.
