Answer:

area if sector=20/360 ×πr²=20×π×6²/360

=2πcm²or 6.28cm²

Answer:

10

Step-by-step explanation:

because 5/15=3x

Let m be the amount each mom can paint and d be the amount each daughter can paint.

On the first day, 8 mothers were painting so the mothers painted 8m square feet. 12 daughters also painted so the daughters painted 12d square feet. The total amount painted on the first day is then 8m+12d square feet. Since 220 square feet was painted on the first day, then 8m+12d=220.  Dividing both sides by 4 gives a simplified equation of 2m+3d=55.

On the second day, 6 mothers were painting so the mothers painted 6m square feet. 8 daughters also painted so the daughters painted 8d square feet. The total amount painted on the second day is then 6m+8d square feet. Since 152 square feet was painted on the second day, then 6m+8d=152

Multiply the first equation by -3 and then add it to the second equation to eliminate m and solve for d:

d=13

2m+3d=55

2m+3(13)=55

2m+39=55

2m=16

m=8

Therefore each mom painted 8 square feet and each daughter painted 13 square feet.

Answer:

(13, 10 )

Step-by-step explanation:

Given the 2 equations

x = y + 3 → (1)

x + 7 = 2y → (2)

Substitute x = y + 3 into (2)

y + 3 + 7 = 2y

y + 10 = 2y ( subtract y from both sides )

10 = y

Substitute y = 10 into (1) for corresponding value of x

x = 10 + 3 = 13

solution is (13, 10 )

the answer is $7

Step-by-step explanation:

70 divided by 14 is 5.

cost would be $5 per person before discount of $2

$5 plus $2 equal $7

Answer:

Step-by-step explanation:

divide each side by 700

=2800/700=700c/700

9514 1404 393

Answer:

  c = 4

Step-by-step explanation:

The equation has a constant on one side of the equal sign, and a variable term on the other side. Solve this by dividing both sides of the equation by the coefficient of the variable.

  [tex]2800=700c \qquad\text{given}\\\\ \dfrac{2800}{700}=\dfrac{700c}{700}\qquad\text{divide both sides by 700}\\\\4 = c \qquad\text{simplify}[/tex]

The value of c is 4.

Answer:

32.85°

Step-by-step explanation:

Used a fancy calculator & just took a test like this

good luck, i hope this helps :)

Answer:

x = 32.8599

Step-by-step explanation:

you have the hypotenuse and the side adjacent to the angle, so you use

Cos(x) = adjacent/hypotenuse

so

Cos(x) = 21/25

x = cos^-1(21/25)

put this in a calculator:

x = 32.8599 (rounded)

Answer:

y=4

Step-by-step explanation:

because this is an equilateral triangle, this means that all the size of the lengths is equal this means that,

2y+5 = 4y-3

(add 3 for both sides)

2y+8 = 4y

(subtract 2y for both sides)

8 = 2y

(divide by 2 for both sides)

4 = y

so,

y=4

Answer: No Solution

Step-by-step explanation:

y=2x+1 and 2x-y=3

Substitute y=2x+1 into 2x-y=3

So you will have: 2x-2x+1=3

Then,

2x-2x=0

0+1=3

1=3

1 doesn't equal 3 so there is no solution.

Answer:

Approx : 14.0294372515

Step-by-step explanation:

There are 2 congruent right triangles in this trapezoid. The hypotenuse and adjacent side lengths are 19 and 17 respectively. Using the Pythagorean Theorem, 19^2-17^2 is 72. The square root of 72 is approximately 8.48528137424. That is the length of the portions on the bottom that don't include the length x. 8.48528137424*2 is approximately 16.9705627485. 31-16.9705627485 gives you the length of the side x.

Answer:

The percentage profit for the year is 62.50%

Step-by-step explanation:

Here, we want to calculate the percentage profit

That would be difference between the revenue (88,000) and the cost (33,000) divided by the revenue * 100%

We have this as;

(88,000-33,000)/88,000 * 100%

= 55,000/88,000 * 100%

= 62.50%

Answer:

Step-by-step explanation:

The numbers of containers in each row form an arithmetic progression, increasing by 3 each row.

common difference = 3

a₁ = 2

a₂₀ = a₁ + (20-1)d = 2 + 19×3 = 59

Total number = 20 × (a₁ +  a₂₀)/2 = 20 × (2 + 59)/2 = 610

Answer:

A) y=3x-2

Step-by-step explanation:

y-y1=m(x-x1)

y-(-8)=3(x-(-2))

y+8=3(x+2)

y=3x+6-8

y=3x-2

Answer:

Many options - 4/6 or 2/3 or 0.66

Step-by-step explanation:

When dividing fractions, we use KCF (keep, change, flip) so our new equation is 1/2 x 4/3. Just multiply! Your answer should be 4/6, and if it needs to be simplified, the answer is 2/3. The answer as a decimal is 0.66 !

Answer:You first would do 1/2 x 4/3 becuase when dividing numbers you use the keep change and flip method. So 1/2 you keep, you change the division sign into a multiplication sign and then 3/4 you flip into 4/3. After that you should have 1/2 x 4/3 and that gets you 4/6. So 4/6 would be your answer but simplified it would be 2/3. - Hope this helps!

Answer:

x-2y = 8

-2y = -x + 8

y = x/2 - 4

y intercept: (0, -4)

slope: 1/2

3x-2y = 12

-2y = -3x + 12

y = 3x/2 - 6

y intercept: (0, -6)

slope: 3/2

I assume I would graph with the following points (0,-4) and (4,0) for the second one I assumed I would graph the following points (0,-6) (6,0). I think I have confused the actual points in which I am to graph. Could you please tell me if I am graphing the correct points? I do not have the ISBN for this book becasue it is an online class. Thanks and have a great day!!

The graph of the function y = 15000 - 3000x represents linear regression.

The general equation of a straight line is -

[y] = [m]x + [c]

where -

[m] → is slope of line which tells the unit rate of change of [y] with respect to [x].

[c] → is the y - intercept i.e. the point where the graph cuts the [y] axis.

We have a finance person who used the function y = 15000 - 3000x to graph depreciation.

We have the following of depreciation -

y = 15000 - 3000x

The graph of the function y = 15000 - 3000x will have a negative slope of -3000. The line makes an obtuse angle with the +x - axis. This type of variation is called linear regression.

Therefore, the graph of the function y = 15000 - 3000x represents linear regression.

Answer:

.9

Step-by-step explanation:

Answer:

suppose x and y are two divided

parts of 4500. then

x+y=4500 __ (1)

given

5% of x = 10% of y

100

5x

=

100

10y

x=2y

2y+y=4500

3y=4500

y=1500

x+1500=4500

x=4500−1500

x=3000

hence the 4500 is been divided into

two parts of 1500 and 3000.

hope it helps you
