Remember that proportions follow the same corresponding sides. Since the first fraction is top right/bottom, the second fraction will follow the same suit.


In this case, the bottom for the bigger figure is DC, so that is your answer.

<h3>Answer: 45 degrees</h3>

The purple arc is 315 degrees. The remaining bit (angle b) must add to 315 to get 360 degrees, which is a full rotation.

315+b = 360

b = 360-315

b = 45

At the farmers market a farmer has bunches of radishes for sale. The
stealth61 [152]

Answer:

The  probability a random selected radish bunch weighs between 5 and  6.5 ounces is 0.8185

Step-by-step explanation:

The  weight of the radish bunches is normally distributed with a mean of  6 ounces and a standard deviation of 0.5 ounces

Mean = \mu = 6

Standard deviation = \sigma = 0.5

We are supposed to find  the  probability a random selected radish bunch weighs between 5 and  6.5 ounces i.e.P(5<x<6.5)

Z=\frac{x-\mu}{\sigma}

At x = 5

Z=\frac{5-6}{0.5}

Z=-2

Z=\frac{x-\mu}{\sigma}

At x = 6.5

Z=\frac{6.5-6}{0.5}

Z=1

Refer the z table for p value

P(5<x<6.5)=P(x<6.5)-P(x<5)=P(Z<1)-P(Z<-2)=0.8413-0.0228=0.8185

Hence the  probability a random selected radish bunch weighs between 5 and  6.5 ounces is 0.8185

A movie-theater employee notes an inverse relationship between the theater's popcorn sales and its nacho sales. On a given night
mario62 [17]

Using proportions, it is found that $1,225 is earned from nachos.

  • This question is solved by <em>proportions</em>, using a rule of three.
  • The measures have an inverse relationship, hence line multiplication is applied instead of cross multiplication.
  • When the theater makes $1,540 from popcorn sales, it makes $1,330 from nacho sales. How much is earned from nachos when $1,672 is earned from popcorn?

The <em>rule of three</em> is:

$1,540 - $1,330

$1,672 - $x

Applying line multiplication:

1672x = 1540 \times 1330

x = \frac{1540 \times 1330}{1672}

x = 1225

$1,225 is earned from nachos.

Which is an equivalent form of the first equation that when added to second equation eliminates the x terms? 4/5 x-3/5y=18
Fittoniya [83]

Answer:

-8x + 6y = -180

Step-by-step explanation:

Given

\frac{4}{5} x-\frac{3}{5}y=18

8x + 12y = 11

Required

Equivalent form of the first equation that eliminates x when added to the second

To do this, we simply make the coefficients of x to be opposite in both equations.

In the second equation, the coefficient of x is 8.

So, we need to make the coefficient of x -8, in the first equation.

\frac{4}{5} x-\frac{3}{5}y=18

Multiply by -10

-10 * [\frac{4}{5} x-\frac{3}{5}y=18]

\frac{-40}{5} x+\frac{30}{5}y=-180

-8x + 6y = -180

<em>When this is added to the first equation, the x terms becomes eliminated</em>
