If ΔWXY is ≅ to ΔPQR, WX=5n-2 and PQ=63 what is n?

1 answer:

3 0

If the two triangles are congruent, then WX=PQ, because they are corresponding(by the order of the letters WXY and PQR). So if they are congruent, then we can say 5n-2=63, by the transitive property. The rest of the problem only requires Pemdas. Add 2 to both sides (5n=65), divide both sides by 5 (n=13), and you find that n=13.

How do you do inverse operation on a fraction ( y/3 ) = -6

NemiM [27]

$\frac{-1}{18}$

Solution:

Given expression is $\frac{y}{3}=-6$

To find the inverse of y.

⇒ $\frac{y}{3}=-6$

Do cross multiplication.

⇒ y = –6 × 3

⇒ y = –18

Inverse of y means reverse the function.

We know that inverse of y is $\frac{1}{y}$ .

⇒ $\frac{1}{y}= \frac{-1}{18}$

Hence, inverse of y is $\frac{-1}{18}.$

Elmer has a collection of 300 fossils. Of those, 21% are fossilized snail shells. How many fossilized snail shells does Elmer ha

kakasveta [241]

Use the percent proportion

21 x
—— = ——
100 300

to solve :
21 x 300 = 6300
6300 ÷ 100 = 63

Answer = 63 of Elmer’s shells are fossilized snail shells :)

Can someone help me with this please

skad [1K]

Answer:

the answer is: 6z^3

Step-by-step explanation:

We need to solve this equation:

$\sqrt{36z^6}$

We know that 6X6 = 36

and √ = 1/2

Solving:

$=\sqrt{6*6*z*z*z*z*z*z}\\We\,\,know\,\,6X6=6^2\,\, and \,\,z*z=z^2\\=\sqrt{6^2*z^2*z^2*z^2} \\=(6^2)^{1/2}*(z^2)^{1/2}*(z^2)^{1/2}*(z^2)^{1/2}\\=6*z*z*z\\=6z^3$

So, the answer is: 6z^3

A rectangle is drawn on a coordinate plane. Three vertices of the rectangle are points

igomit [66]

Answer:

Step-by-step explanation:

The distance from B to C is the same as the distance from A to D. Points B and C will both have the same x-value, as do points A and D. Points B and C will have the same difference in y-values (2 -(-2) = 4) that points A and D have.

The distance from B to C is 4 units.
