as a club fundraiser, a group of students washed 40 cars one weekend,they washed 70 cars. what was the percent increase in the n

Degger [83]

Answer:

75%

Step-by-step explanation:

To know the answer, you should take into account that, 70 equals 1,75 times 40.

This is because $\frac{70}{40}=1,75$ .

Then, if 70 equals 1,75 times 40, it is 0,75 = 75% greater than 40.

Quadrilateral MNPQ is the same shape but a different size than quadrilateral M'N'P'Q'

I am Lyosha [343]

If the shape is the same, but the size is different, <em>dilation is involved</em>. There may be other transformations that are also involved (such as rotation, translation, or reflection), so MNPQ may or may not be a straight dilation of M'N'P'Q'.

_____

Translation and dilation can sometimes be combined to a dilation about a point that is not the origin. Reflection might be accommodated by using a negative dilation factor. However, rotation cannot be accomplished using dilation alone.

Use the quadratic formula to solve the equation x^2-7x-6=0

olganol [36]

Answer:

$\frac{7\pm\sqrt{73}} {2}$

Explanation:

We have been given with the quadratic equation $x^2-7x-6=0$

We have general formula to find the roots of a quadratic equation first we find the discriminant with formula

$D=b^{2}-4ac$

and after that to find the variable suppose x we have the formula

$x=\frac{-b\pm\sqrt{D}} {2a}$

And general quadratic equation is

$ax^2+bx+c=0$

On comparing the given quadratic equation with genral quadratic equation we will have values

a=1, b=-7 and c=-6

After substituting these values in the formula we will get

$D=(-7)^2-4(1)(-6)={73}$

After substituting in the formula to find x we will get

$\frac{-(-7)\pm\sqrt{73}} {2}= \frac{7\pm\sqrt{73}} {2}$

How would u find the answer idk if they would still be the same and you just have to find that one missing angle?

ivolga24 [154]

Well... with the information you are given you just have to assume they are congruent triangles. The first picture looks like a right triangle, but the angle is 100 not 90... so it wouldn't actually look like that.

So for the missing angle all you do is 180= 100+ 55 + x

x=25

Then just match up the angles with the other triangle, they would be the same. K with F, J with G, and so on
