In circle O, RT and SU are diameters. If m = m, what is m? 47° 52° 64° 87°
vlada-n [284]
From the given figure, it can be seen that 13x = 15x - 8 because they are vertical angles and thus are equal.

13x = 15x - 8
15x - 13x = 8
2x = 8
x = 8/2 = 4

Thus, 15x - 8 = 15(4) - 8 = 60 - 8 = 52.

RT is a diameter, which means that mRT = 180

mRV + mVU + 52 = 180

mRV + mVU = 180 - 52 = 128

Now, given that mRV = mVU,

Thus, 2mVU = 128

Therefore, mVU = 128 / 2 = 64°

Adrienne operates the milkshake machine at Burgers and Shakes. on Monday she added whipped cream to 210 shakes.This was 70% of t
Natalka [10]

Answer:

Total number of milkshakes sold on Monday = 300

Number of milkshakes without whipped cream = 90

Step-by-step explanation:

Given:

Adrienne adds whipped cream to 210 milk shakes which is 70% of the total milk shakes sold.

To find the total milkshakes sold.

Solution:

Let the total number of milkshakes sold on Monday be = x

Percentage of milkshakes with whipped cream added to them = 70%

Number of milk shakes with added whipped cream can be given as:

⇒ 70\% \textrm{ of the total number of milkshakes}

⇒ 70\% x

⇒ \frac{70}{100}x  [Representing percent in fraction form]

⇒ 0.7x  [evaluating in decimals]

We know that the number of milkshakes with whipped cream added to them = 210.

So, we have:

0.7x=210

Solving for x

Dividing both sides by  0.7

\frac{0.7x}{0.7}=\frac{210}{0.7}

∴ x=300

Thus, total number of milkshakes sold on Monday = 300

Number of milkshakes without whipped cream = 300-210= 90
