Answer:
I believe it is 63 although i may be doing the wrong formula. but as far as i can tell thats right.
Step-by-step explanation:
Hello, well there are a few ways to write this. Here is one outlook.
Bruce bought three boxes of tiles with the same number of tiles in each.
x = number of tiles
3 = number of boxes
3x = total number of tiles.
Make note, the problem is asking for an expression for how many tiles he used and not the total number of tiles he has. Anyways, the problem then tells us he had to go get 3 more boxes but he used only 2 tiles out of the last box. So he used 2x + 2 tiles We put this together and we have
3x + 2x + 2
5x + 2
Number of tiles Bruce used = 5x + 2
We do the same for Felicia:
She gets 5 boxes, which = 5x. Then she had to go back and just get 5 tiles. So we have:
5x + 5
Number of tiles Felicia used = 5x + 5
Answer:
For the first question, 180 degrees equals to a half of the sphere. For the second question, you need 24 central meridians for a complete sphere, which are exactly the hours in a day.
Step-by-step explanation:
A sphere is basically a 3D circle. As a circle has 360 degrees, 180 degrees would be half of a circle. Imagine you are on a satellite over the north pole or the south pole and you have a way to cut the earth by the middle. You will get two halves of sphere.
About the second question, you may need to have in mind that a day is the time spent for the earth to rotate all 360 degrees over its own axis. British fellow, on XIX century, decided they were the center of the world. As previously, back in the days, some other people decided a day had 24 hours, they decided to draw this lines and divide the earth in 24 pieces, so they could knew which time was on every point their extense kingdom had. As I said, a circle has 360 degrees, (360 degrees)/(24 hours) equals to 15 degrees.
The complete factored form of the quadratic expression is (x-8y)(x-8y)
<h3>Factorizing quadratic expression</h3>
Quadratic expressions are expressions that has a leading degree of 2
Given the expression
x^2 – 16xy + 64y^2
Factorize
x^2 - 8xy - 8xy + 64y^2
Group
(x^2 - 8xy) - (8xy + 64y^2)
x(x-8y) - 8y(x - 8y)
Since (x-8y) is common, hence;
x^2 - 8xy - 8xy + 64y^2 = (x-8y)(x-8y)
The complete factored form of the quadratic expression is (x-8y)(x-8y)
