Answer:
1.2 * 10^3
Step-by-step explanation:
3.12 * 10^8
=========
2.6 * 10^5
Start by doing 3.12 / 1.6 = 1.2 and that is the correct number of sig digs.
Now get the power on the 10. When dividing, the powers subtract.
10^(8 - 5)
10^ 3
The answer is 1.2 * 10^3
Find the area of the rectangle. 39 times 16=
624-pi (radius squared)
624-3.14 times 8 squared
624- 200.96
423.04 cm ^2
<span>6840 customers ... 45 days<span>
x customers = ? ... 1 day
If you
would like to know how many customers were in Jasigreen's class in 1 day,
you can calculate this using the following steps:
6840 * 1 = 45 * x
6840 = 45
* x /45
x = 6840 / 45
x = 152 customers
<span>The
correct result would be </span>152 customers<span>.</span></span></span>
Answer:
15 kilometres
Step-by-step explanation:
Based on the wording of your question, I am assuming you already know that Paul ran 250 metres every 1 minute, and that the ratio is 250:1. To get the second part of the answer, convert metres to kilometres. 0.001*250= 0.25. Paul ran 0.25 kilometres per minute. The ratio of kilometres per minute is 0.25:1. Next, convert minutes to hours. Multiply the entire ratio by 60, as there are 60 minutes in an hour. The ratio of kilometeres per minute is 15:60, and the ratio of kilometres per hour is 15:1, meaning Paul ran 15 kilometres in one hour.
Answer:
x= $878.85
Step-by-step explanation:
1349.99=1350
1350=100% you cross multiply and then divide by 100 you get x = 540
x =40%
504 is how much can be off the original price, 1350-504=810
You would pay 810 dollars if the coupon was 40% off. Now we gotta find how much is the tax rate.
810=100% do the cross multiply and then divide by a 100, you get x=68.85
x =8.5
Then you have to add your tax rate to the price that you are paying, 810+68.85=$878.85.
Hope this helps you!
