The number of 7th graders attending Middlefield Science Academy this year is 130% of last year’s total. If 500 7th graders atten

ded last year, how many attend this year? A tape diagram. There are 130 students who are 7th graders this year out of 100 who were 7th graders last year. There are question mark students this year out of 500 who were 7th graders last year. Which steps should be used to find 130% of 500? Check all that apply. (100)(50) = 500 (100)(5) = 500 (130)(5) = 650 StartFraction 130 Over 100 EndFraction = StartFraction 130 Over 100 EndFraction = StartFraction 650 Over 500 EndFraction There are 650 7th graders this year.

Simplify: X^-3/x^0<br><br> (Trying to get more characters)
scZoUnD [109]

Answer:

1 / x^3

I don't know what you mean by trying to get more characters by the way sorry.

Step-by-step explanation:

Exponents rule will change X^-3 / x^0 to x^-3-0

Subtract the exponents to get x^-3

Since exponents cannot be negative, the answer will be changed to a fraction 1/x^3.

A triangle has angle measures of 95° and 65° What is the measure of the third angle <br>​
Svetradugi [14.3K]
The third angle is 20°. This is because you add the two angles you have already (95+65) and then you subtract that from 180. In simplier words: If you know 2 angles then you can subtract their sum from 180° to find the measure of the 3rd angle.

NO LINKS!! Please help me with this problem​
12345 [234]

Answer:

\frac{x^2}{784}+\frac{y^2}{400}=1

Step-by-step explanation:

<u><em>Horizontal Major Axis:</em></u>

   \frac{(x-h)^2}{a^2}+\frac{(y-k)^2}{b^2}

<u><em>Vertical Major Axis:</em></u>

   \frac{(y-k)^2}{a^2}+\frac{(x-h)^2}{b^2}+

So these two expressions are essentially the same with the only difference being the location of "a" and "b". The length of the major axis will be "2a" and the length of the minor axis will be "2b". The way I remember this is because when you have the horizontal major axis the "a" value is in the denominator of the (x-h) and I think of "x" as a horizontal value, since it moves a point horizontally. When you have a vertical major axis the "a" value is in the denominator of (y-k) and I think of "x" as a vertical value, since it moves a point vertically.

So just by looking at the graph, you can easily determine that the eclipse has a horizontal major axis. This can be further proven, since the distance from the origin on the right side is 28, and the distance from the the top to the origin is only 20.

So you could set up an equation to solve for a, since 2a = length of major axis, but since we're given the two points, the "a" value is really just the length from the origin to the right/left side, and combining these together you get the value of 2a/major axis, but you don't have to do that. So by looking at the graph you'll see the distance from the origin to the right side is 28. This means "a=28"

You can do the same thing here for the "b" value, and since the top is 20 units away from the origin, "b = 20"

So now let's set up the equation:
\frac{x^2}{28^2} + \frac{y^2}{20^2}=1

Square the values in the denominator

\frac{x^2}{784}+\frac{y^2}{400}=1
