Answer 1
Answer:
Tell you what I'm gonna do: I'll show you the work, and then YOU can take the final steps to the answer.
Alisha needs $228. She has been saving up for it. How much more does she need ? We'll know that, as soon as we figure out how much she has now.
She has saved $4.75 each week for the past 8 weeks. That means she has put $4.75 into a jar 8 times. So now, she has 8 times $4.75 .
How much is 8 times $4.75 ?
The difference between $228 and that number is how much more she needs.
The first thing you need to know is the distance all the way around the patio. The patio is in the shape of a circle, so the distance around it is called the "circumference". You need the length of that.
Fortunately, you have a simple formula for the circumference of a circle:
Circumference = (pi) times (the diameter of the circle) .
The diameter is 24.2 feet.
Circumference = (pi) times (24.2 feet) = about 76 feet .
Now, all you need to do is figure out how many strings of lights you need, for them to add up to 76 feet.
Each string of lights is 57 inches long. You need to know how many times you need 57 inches, to add up to 76 feet.
Well first of all, I hope you can see that you have to divide ... to find out how many short pieces will make one long piece.
But there's another little wrinkle here: The big distance is in feet, and the short pieces are in inches, so you can't just go ahead and divide 76 by 57. I mean, you could, but the answer wouldn't mean anything. Before you divide, both of your lengths need to be in the same units, so you need to change one of them. You have a choice to make: Either change the 76 feet into inches, or else change the 57 inches into feet. Either way works fine.
There are 12 inches in one foot.
-- 76 feet = (76 x 12) = 912 inches.
(912 inches per patio) divided by (57 inches per light string) = 16 light strings per patio
or
-- 57 inches = (57/12) = 4.75 feet
(76 feet per patio) divided by (4.75 feet per light string) = 16 light strings per patio
See ? Either way works fine.
What is 132654 rounded to the nearest hundred thousand
Answers
When rounding, always look to the number directly to the right of the number in the place that must be rounded. If the number is 5 or exceeds 5, change the number in the place that must be rounded to one higher number. If nothing exceeds, keep the number as is and change all other preceding places to 0.
In this case, your hundred thousand place would not change because the 3 next to it does not exceed 5.
Therefore, it will be 100,000
Hope this helps :)

Use absolute value to express the distance between 10 and -4
Answers
Absolute value does not include direction, therefore, does not have a negative sign. Always positive.
The distance between 10 and -4 is 14.
I showed why in the attachment below.
So, since we do not include the sign, your final answer is 14.
Final answer: 14
