Angle 1 and angle 5 are equal so you can set the equations equal to each other. 60 - 2x = 70 - 4x
60 + 2x = 70
2x = 10
x= 5

I need help with this problem

Answer:

4*x^4*y^22

Step-by-step explanation:

Your goal here is to REDUCE the given expression to simplest terms.

One way in which to approach this problem would be to rewrite (2x^2y^10)^3 as: (2x^2*y^8)*y^2*(2x^2*y^10)^2.

Dividing this rewritten expression by 2x^2*y^8 results in:

y^2(2x^2*y^10)^2.

We now need to raise (2x^2*y^10) to the power 2. Doing this, we get:

4x^4*y^20.

Multiply this by y^2 (see above):

y^2*4x^4*y^20

The first factor is 4: 4y^2*x^4*y^20. This is followed by the product of y^2 and y^20: 4*y^22*x^4

Finally, this should be re-written as

4*x^4*y^22

Another way of doing this problem would involve expanding the numerator fully and then cancelling out like factors:

8*x^6*y^30 4*x^4*y^22

----------------- = ------------------ = 4*x^4*y^22

Ivan has 15 yards of green felt and 12 yards of blue felt to make 3 quilts if Ivan uses the same total number of yards for each

mixas84 [53]

Answer:

9 yards

Step-by-step explanation:

Let the length of each quilt be 'l'.

Given:

Length of green felt (g) = 15 yards

Length of blue felt (b) = 12 yards

Total number of quilts = 3

Now, the length of 3 quilts is given as:

$Total\ length=l+l+l=3l$ ----- (1)

As per question:

Total length = Length of green felt + Length of blue felt

Total length = $g+b$

$Total\ length=15+12=27$ --------- (2)

Now, comparing equations (1) and (2), we get:

$3l=27\\\\l=\frac{27}{3}\\\\l=9\ yards$

Hence, each quilt measures 9 yards in length.

What is the best approximation of the value of w? 1. 4 cm 4. 0 cm 6. 0 cm 7. 3 cm.

MrRissso [65]

To solve the problem we must know about Sine Rule.

<h3>What is Sine rule?</h3>

The sine rule of trigonometry helps us to equate the side of the triangles to the angles of the triangles. It is given by the formula,

$\dfrac{Sin\ A}{\alpha} =\dfrac{Sin\ A}{\beta} =\dfrac{Sin\ A}{\gamma}$

where

Sin A is the angle and α is the length of the side of the triangle opposite to angle A,
Sin B is the angle and β is the length of the side of the triangle opposite to angle B,
Sin C is the angle and γ is the length of the side of the triangle opposite to angle C.

The value of w is 4.0 cm.

Given to us

VW = 3.3 cm,
∠U = 31°,
∠W = 39°,

<h3>Using the sine law,</h3>

$\dfrac{Sin\ A}{\alpha} =\dfrac{Sin\ A}{\beta} =\dfrac{Sin\ A}{\gamma}$

Substitute the values,

$\dfrac{Sin\ W}{w} = \dfrac{Sin\ U}{VW}$

$\dfrac{Sin\ 39^o}{w}=\dfrac{Sin\ 31^o}{3.3}$

$w=\dfrac{(Sin\ 39^o) \times 3.3}{Sin\ 31^o}$

w = 4.03224 cm ≈ 4.0 cm

Hence, the value of w is 4.0 cm.
