Answer:

47. 1 5/8

48. 1 1/12

Step-by-step explanation:

47.

First, convert the denominators to be the same.

8 1/2 minutes, Ruby's mile time, can be converted to 8 4/8.

Then subtract.

8 4/8 - 6 7/8 = 1 5/8

48.

Make sure the denominators are the same. Both denominators can be multiplied by 3 or 4 to become 12.

1 1/4 can be multiplied by 3 to get 1 3/12. And 1 1/3 can be multiplied by 4 to get 2 4/12.

Then subtract.

2 4/12 - 1 1/3 = 1 1/12

In ΔVWX, the measure of ∠X=90°, XW = 36, WV = 85, and VX = 77. What ratio represents the sine of ∠W?

eimsori [14]

Given:

In ΔVWX, the measure of ∠X=90°, XW = 36, WV = 85, and VX = 77.

We need to determine the ratio that represents the sine of ∠W

Ratio of sin of ∠W:

The ratio of sin of ∠W can be determined using the trigonometric ratios.

The ratio of $sin \ \theta$ is given by

$sin \ \theta=\frac{opp}{hyp}$

From the attached figure, the opposite side of ∠W is XV and the hypotenuse of ∠W is WV.

Hence, substituting in the above ratio, we get;

$sin \ W=\frac{XV}{WV}$

Substituting the values, we get;

$sin \ W=\frac{77}{85}$

Thus, the ratio of sine of ∠W is $sin \ W=\frac{77}{85}$

The pattern is 4, 12, 36, 108, 324, 972, 2,916

4+8=12
12+24= 36
36+72= 108
108+216=324 .... and so on

UW= 2 and UX=y. Write an expression for WX

Eddi Din [679]

Divide each term by U and simplify. X=y/U and W=2/U. Next, solve the equation for y. Simplify the left side then cancel the common factor of U. 1/1*y/1=y

W=2/U. Multiply 1/1*y/1=y/1 so, y/1=y and W=2/U. Next, divide y/y to get 1 now y=y, still W=2/U. Now, move all terms containing y to the left side. Since, Y contains the variable to solve for, move it to the left side of the equation by subtracting y from both sides. Now, y-y=0 still W=2/U. Next, subtract y from y to get zero and still W=2/U. Subtract y from y to get zero or 0=0 and W=2/U is your expression since 0=0.

Next: UW=m and WX=y+14 write expression for UX

First, divide each term by W and simplify. U=m/W, WX=y+14. Next, solve the equation for Y. Move y from the right side of the equation to the left side. Still, U=m/W and y=-14+WX. We must reorder -14 and WX. U=m/w and y=WX-14.
Replace the variable U with m/W in the expression to (m/W)X. Next, simplify (m/W)X. Now, write X and a fraction with denominator 1. Looks like this
fractions are side by side m/W X/1 . Multiply, m/W and X/1 to get mX/W.
mX/W is your final expression for UW=m and WX=y+14 expression for UX.
