Answer:

  13

Step-by-step explanation:

If we assume that points P, Q, R, S are in that order on a arc centered at O, then we have ...

  ∠POQ +∠QOS = ∠POR +∠ROS

  ∠ROS = ∠POQ +∠QOS -∠POR

  ∠ROS = 28 +46 -61 = 13

A fine jewelry store leased a space at the mall with a base rent of $1,800 a month, plus 4% of all sales over $200,000. If the gross sales were $325,000, what was the total amount of rent paid by Heinz Fine Jewelry at the end of the year?

Answers

Answer:

So, first, we have to establish how much the base rent ends up costing. So to find that, we do 1,800x12=21,600. So the base rent is $21,600. Then, we add the 4% of sales which is 125,000x0.04=5,000. So, we add $21,600 with $5,000 and we get a final answer of $26,600 owed at the end of the year :)

Using the slope formula, find the slope of the line through the given points. (4. - 2) and ( - 2, - 2)​

Answers

Answer:

- 0/6

Step-by-step explanation:

*I’m pretty sure you meant to type “(4, -2)” instead of “(4. -2)” Anyways…*

m = slope

m = change in y/change in x

m = y2 - y1/x2 - x1

Points: (4, -2) and (-2, -2)

m = -2 - -2/-2 - 4

m = 0/-6

The slope is - 0/6

Hi! I'm happy to help!

To solve this problem, we have to find the slope, which is rise over run, or how much the line rises and how far forward the line goes.

We find the slope using this formula (slope formula)

m(slope)=[tex]\frac{y_{2}-y_{1} }{x_{2} -x_{1} }[/tex]

This refers to the second y point minus the first y point, divided by the second x point minus the first x point. Y refers to the y axis, so that is the rise, because it is the difference of height in the line. X refers to the x axis, so that is the run, because it is the difference in how far it travels forward.

Our second y point is -2, our first y point is also -2. Our second x point is -2, and our first y point is 4. Let's plug in our values.

[tex]\frac{-2-(-2)}{-2-4}[/tex]

Let's simplify this so there isn't a double negative.

[tex]\frac{-2+2}{-2-4}[/tex]

Now, let's solve

[tex]\frac{0}{-6}[/tex]

0 divided by -6, is still 0, so there is no slope or the slope is 0. This means that the line is horizontal and the y coordinate doesn't change.

I hope this was helpful, keep learning! :D

Find the total surface area.

C. 198.6 mi²
D. 99.5 mi²

Answers

Answer:

B. 143.4 [tex]\text{mi} ^2[/tex]

Step-by-step explanation:

In simple terms, surface area =  adding area of all surfaces

This figure has 6 sides.

Surface area = 2 * area of trapezium + 2* area rectangle + area of bottom rectangle + area top rectangle

Surface area = 2 * ([tex](\frac{a+b}{2}) * h + 2* (l*w) + l*w + l*w[/tex])

= [tex]2 * (\frac{3+6}{2} * 2.6) + 2* (8*3) + 3*8 + 8*6[/tex]

2.) Given that 3x+2=4 and 2y+6=5, what is x+y?

Answers

part 1

2x-8x=-5-3

6x=-2

6x/6=-2/6

x=-3

part 2

I can't so please help me

Answer:

Step-by-step explanation:

One

2x + 3 = 8x - 5                Add 5 to both sides

2x + 3 + 5 = 8x               Combine

2x + 8 = 8x                      Subtract 2x from both sides.

8 = 8x - 2x                       Combine

8 = 6x                              Divide by 6

x = 8/6

x = 8.333

Two

3x + 2 = 4                       Subtract 2 from both sides

3x = 4 - 2

3x = 2                             Divide by 3

x = 2/3

2y + 6 = 5                     Subtract 6 from both sides

2y = 5 - 6

2y = -1                          Divide by 2

y = - 1/2

x + y = 2/3 - 1/2

x + y = 4/6 - 3/6

x + y = 1/6

3. A clock is constructed using a regular polygon with 60 sides. The
polygon rotates every minute. How much has the polygon rotated
after 12 minutes? Explain your answer with words, a drawing or both-

Answers

We are required to find how much the polygon has rotated after 12 minutes

The number of times the polygon has rotated after 12 minutes is 72°

Number of sides of the polygon = 60

The polygon rotates every minute, that is

1 rotation = 1 minutes

12 rotation = 12 minutes

one rotation of the clock is 360°

Number of times the polygon has rotated after 12 minutes = one rotation of the clock / Number of sides of the polygon × number of minutes

= 360°/60 × 12

= 6 × 12

= 72°

There are five boys to every three girls in an introductory chinese course. if there are 384 students enrolled in the course, how many are boys?

Answers

Answer:

There are 240 boys.

Step-by-step explanation:

There are five boys to every three girls in an introductory Chinese course. Given that there are 384 students enrolled in total, we want to determine the amount of students which are boys.

Let b represent the number of boys and g girls.

Since the ratio is 5:3, we can write that:

[tex]\displaystyle \frac{5}{3} = \frac{b}{g}[/tex]

And since the total number of students is 384:

[tex]b + g = 384[/tex]

From the first equation, cross-multiply:

[tex]5g = 3b[/tex]

Solve for g:

[tex]\displaystyle g = \frac{3}{5} b[/tex]

Substitute:

[tex]\displaystyle b + \left (\frac{3}{5} b\right) = 384[/tex]

Simplify:

[tex]\displaystyle \frac{8}{5} b = 384[/tex]

Solve for b:

[tex]\displaystyle b = \frac{5}{8}\left(384\right) = 240[/tex]

In conclusion, 240 of the total students are boys.

To find the value of the home after the tenth year?

What is simple interest?

Simple Interest (S.I.) is the method of calculating the interest amount for a particular principal amount of money at some rate of interest.

Given that:

Principal=P=$225000

Rate of interest=R=3%

Time=10 year

By the use of formula:

[tex]I=\frac{PRT}{100}[/tex]

[tex]I=\frac{225000*3*10}{100} \\\\I=22500*3\\\\I=67500[/tex]

So, the value of the home after the tenth year is 67500.

Your answer should be C :-)

Answer:

B

Step-by-step explanation:

(7×2)⁶

when we put a number to the power of something, we need to include the whole number. bit just a part of it.

so, it must be 7⁶×2⁶

just think about the simple example 6², which we could write as (2×3)².

would it be sufficient to e.g. square only one of the factors ?

6² = 36

but e.g. 2×3² = 18. so, that's really not it.

or add the two factors and then square them ?

2+3 = 5. 5² = 25. so, that's not it either.

or multiply the exponent in ?

2×3×2 = 12. so that's not it either.

no, it truly is you need to do the operation to all parts.

2²×3² = 4×9 = 36. yes, that fits.

therefore, B is the right answer.
