8 0

Answer:

It could be 8 or 5. I think it's 5

Step-by-step explanation:

This is a pretty weird problem. I see the DC is 10 so then one would think that it is 5. EF however is 7. I think the most logical answer would be 5. Using process of elimination, we can narrow it down to 5 and 8 but I feel that 5 makes more sense. the other 2 sides are obviously longer so 5 is most likely correct.

Tessa bought stock in a restaurant for $166.00. Her stock is now worth $202.52. What is the percentage increase of the value of

siniylev [52]

Answer:

$p = .22 = 22 \: \: percent \: increase$

Step-by-step explanation:

$166(1 + p) = 202.52$

$1 + p = \frac{202.52}{166}$

$p = \frac{202.52}{166} - 1$

An automobile repair facility recently purchased a 200-foot roll of flexible plastic tubing for $47.03 . Compute the cost in cen

mojhsa [17]

The cost is 24 cents per foot.

We find this by dividing the cost of the roll by the number of feet in the roll:

47.03/200 = 0.235 ≈ 0.24

What are the values of M and theta in the diagram below

Montano1993 [528]

Answer:

The correct answer is m= $\frac{\sqrt{3} }{2}$ and θ = 30º.

Step-by-step explanation:

First, we must form a triangle whose hypotenuse is the radius r=1, its adjacent leg is m, its opposite leg is $\frac{1}{2}$ and the angle is theta.

First, we calculate the angle with theta's breast:

sin (θ) = $\frac{\frac{1}{2} }{H}$

where H is the hypotenuse, in this case, the radio.

θ = $sin^{-1}$ ( $\frac{\frac{1}{2} }{1}$ )

θ = 30º

Now, we calculate the adjacent leg, which is equal to the x-coordinate of the point:

cos (θ) = $\frac{m}{H}$

m = cos 30º * H

m = $\frac{\frac{\sqrt{3} }{2} }{1}$

m = $\frac{\sqrt{3} }{2}$

Have a nice day!
