The polygons in each pair are similar. Find the missing side length.

Answer:

12

Step-by-step explanation:

If you flip the polygon on the right so it looks like the polygon on the left, the scale factor for the small polygon to the big polygon is 32/40 or 4/5.

Now use that scale factor, 4/5, to find the missing length

4/5 = ?/15

5*3 = 15 so 4*3 = ?

? = 12

A right triangle has legs that measure 7 cm and 6 cm. What is the length of the hypotenuse in meters?

<h2>Greetings!</h2>

Answer:

\sqrt{85}  or 9.22

Step-by-step explanation:

You need to remember the following equation:

a^{2} + b^{2} = c^{2}

Where a and b is the lengths of the two sides and c is the hypotenuse.

So simply plug these values into this:

6^{2} + 7^{2} = h^{2}

36 + 49 = h^2

36 + 49 = 85

So the hypotenuse is the square root of 85:

\sqrt{85}  = 9.22

Jennifer has 25 coins with a total value of $4.25. The coins are quarters and nickels. How many of each does she have?
kirill115 [55]

Answer:

15 quarters, 10 nickels

Step-by-step explanation:

q+n=25

0.25q+0.05n=4.25

multiply the first equation by -0.25 and add the second equation to it

-0.25q-0.25n=-6.25\\0.25q+0.05n=4.25
________________
                -0.2n=-2

n=\frac{-2}{-0.2} =10   has 10 nickels

q=25-n=25-10=15  has 15 quarters

10(.05) +15(0.25) = 0.5 + 3.75 = 4.25

Hope this helps

Grade 10 math help please. Please show work
masha68 [24]

Answer:

43.94?

Step-by-step explanation:

I think if you use inverse cos you should get the correct number. So, to find cos, you need to know the adjacent side and the hypotenuse. Here, the reference angle would be the person holding the kite. The distance from the person to the barn is the adjacent side, which is 18. The string of the kite, I assume, would be 25.

cos(∅) = \frac{18}{25}

cos(∅) = 0.72

cos⁻¹(0.72) = 43.94

I don't know if that's what you're looking for, but... If it's not correct, lmk so I can rewrite it. :)
