Assuming the entire quadrilateral is a parallelogram, we can say that using the property of diagonals;

The diagonals of a parallelogram bisect each other, meaning that RQ is divided into two equal parts.

If half of RQ is 9.3 then,

RQ=2×9.3=18.6 in

That's your answer RQ=18.6 in

Your answer is 24.

Step-by-step explanation:

The data set is 22,23,23,23,24,24,25,26,26,26,28

The median of this set is 24

The mean is 24.54

The mode is 23,26

The range is 6

Salary after 10 years at the company will be 3s+2000.

It is given that original salary =s

The multiplication of a variable x to constant p is px.

Salary after 10 years as per promise = thrice of original salary +$2000

Salary after 10 years = 3*s + 2000

Salary after 10 years = 3s+2000

Therefore, salary after 10 years at the company will be 3s+2000

Answer:

Step-by-step explanation:

You want to identify the expressions equivalent to 11x -4x +6x and 3(1 +9y).

We can identify the equivalent expressions by putting them all in their simplest form. This means using the distributive property to eliminate parentheses, and combining like terms.

The simplified version of the given expression is ...

  (11 -4 +6)x = 13x

The other expressions simplify to ...

  7x +6x = (7+6)x = 13x . . . equivalent

  7x -6x = (7 -6)x = 1x = x . . . not equivalent

  13 +x (already simplest) . . . not equivalent

  13x (already simplest) . . . equivalent

The simplified form of the given expression is ...

  3·1 +3·9y = 3 + 27y

The other expressions simplify to ...

  3 +1·3 +9y = 6 +9y . . . not equivalent

  3 +27y . . . equivalent

  3·1 +3·9y = 3 + 27y . . . equivalent

  3 +9y (already simplest) . . . not equivalent

Answer:

They would each pay $7.15

Answer:

The answer to the question is 5:3:4

Answer:

$2.22

Step-by-step explanation:

First, we know that the cost of one mailing letter is $0.23 per once, plus $0.14.

Our formula is: c = 0.23w + 0.14

Let's rewrite our variables to the way it's suppsed to be.

C = cost

W = weight ounces.

Now, we have to add 0.23 plus 0.14 to get our cost.

That equals 0.37.

Now that we know that our cost for one letter is 0.37, we have to multiply

it by 6, because we are trying to figure out the cost of mailing a 6 ounce letter.

0.37 × 6 = 2.22

In conclusion, the cost of mailing a 6 ounce letter is $2.22

Answer:

y=2x+1

Step-by-step explanation:

The point-slope form is (y-y1)=m(x-x1), with x1 and y1 being the coordinates from ordered pair, and m being the slope. You can plug all of those values into the original equation:

(y-y1)=m(x-x1)

y-3=2(x-1)

y-3=2x-2

y=2x+1

Answer:

Loss=Rs 80

Loss%=4%

Step-by-step explanation:

Cost price of trousers for Ujeli=Rs2000

Marked price for trousers =Rs 2400

Reduction of MP(take it as discounted) =20%

Selling price=MP-20%of MP=2400 - 20/100 * 2400 = 2400 - 480 = Rs 1920

Loss amount =CP - SP = 2000 - 1920 = Rs 80

Loss% =loss amt/CP *100 =80 / 2000 *100 =4%

Answer:

25

Step-by-step explanation:

complementary angles is when their sum = 90 so

30 + 2x + 10 = 90

2x = 90 - 40

2x = 50

X = 25

Answer:

x = 25

Step-by-step explanation:

1. Due to the fact that Angle F and angle G are complementary, 2x + 10 + 30 = 90.

2. Solve this equation: 2x + 10 + 30 = 90

Add 10 and 30

2x + 10 + 30 = 90

2x + 40 = 90

3. Subtract 40 from 90

2x + 40 = 90

2x = 90 - 40

2x = 50

4. Divide 2 from 50

x = 50/2

x = 25

Answer:

g(x) = - 16x² + 4

Step-by-step explanation:

Given the model:

First drop:

h(x) = - 16x² + 64

Second drop hits the ground 1.5 seconds sooner

Function g(x) to model the second drop:

-16t² + V0t + h0

h(x) = - 16x² + 64

0 = - 16x² + 64

16x² = 64

x² = 64/16

x = 2

1.5 seconds sooner :

X = 2 - 1. 5

x = 0.5

0 = - 16(0.5)² + 0 + h0

0 = - 4 + h0

h0 = 4

Hence,

g(x) = - 16x² + 4

Step-by-step explanation:

13 coins and 5 quartres

Answer: Below

Step-by-step explanation:

First, we start with x. We see the x is opposite of 30, so x is 30.

x + y + y = 180, since they lay on a straight angle.

180 - 30 = 150

since we still have 2 y's left:

2y = 150

y = 75

She will receive 22% commission

Step-by-step explanation:

18% commission when the profit on a car is under $400

22% when the profit is at least $400 and less than $1,000

24% when the profit is $1,000 or more.

How much will she receive if she sold $800 in profits?

She will receive 22% commission

$800 profits is greater than $400 but less than $1000

Answer:

$90

Step-by-step explanation:

We use the simple interest formula,

I = Prt

where

I = interest

P = principal amount = $500

r = interest rate = 6% = 0.06

t = time = 3 years

I = Prt

I = $500 × 0.06 × 3

I = $90

The actual width of the entire building is 28 feet and the length of the entire building is 84 feet.

Given that, the scale for the blueprints to the actual house is 2 inches to 7 feet.

The scale factor is defined as the number or the conversion factor which is used to change the size of a figure without changing its shape. It is used to increase or decrease the size of an object. The scale factor can be calculated if the dimensions of the original figure and the dimensions of the dilated (increased or decreased) figure are known.

Scale factor = Dimensions of the new shape ÷ Dimensions of the original shape.

Now, width = 8 inches in feet is 4 × 7 =28 feet

Length = 14+10 =24 inches in feet is 12 × 7 = 84 feet

Therefore, the actual width of the entire building is 28 feet and the length of the entire building is 84 feet.

Answer:

its linear (i know  how to draw the graph but i cant show you here, just make umm an x axis and y axis from 1 to 30 ) (also i feel like theres another way to know if its linear but this is how i would do it!)

Step-by-step explanation:

to see if its linear ummm we first have to find the slope, the equation for the slope is

y2 - y1 / x2 - x1

lets use the points (2, 8) and (3, 12)

12 - 8/ 3 -2

4 / 1

4

y = 4x + b

now to find the y-intercept lets input a point we did not use yet

(5, 20)

20 = 4(5) + b

20 = 20 + b

b = 0

y = 4x

now we check if its linear with the points  (6, 24) and (3.5, 14) sooo

24 = 4(6) ?

24 = 24

14 = 4(3.5) ?

14 = 14

so yes it is a linear graph

Answer:

Charges of Turkey is $6.25

Charges of French Fries is $1.90

Step-by-step explanation:

Given

Represent Turkeys with T and French Fries with F;

[tex]4T + 7F = 38.3[/tex]

[tex]5T + 5F = 40.75[/tex]

Required

Determine the values of T and F

[tex]5T + 5F = 40.75[/tex]

Divide through by 5

[tex]T + F = 8.15[/tex]

Make F the subject

[tex]F = 8.15 - T[/tex]

Substitute 8.15 - T for F in the first equation

[tex]4T + 7F = 38.3[/tex]

[tex]4T + 7(8.15 - T) = 38.30[/tex]

[tex]4T + 57.05 - 7T = 38.30[/tex]

Collect Like Terms

[tex]4T - 7T = 38.30 - 57.05[/tex]

[tex]-3T = -18.75[/tex]

Solve for T

[tex]T = -18.75/-3[/tex]

[tex]T = 6.25[/tex]

Recall that:

[tex]F = 8.15 - T[/tex]

[tex]F = 8.15 - 6.25[/tex]

[tex]F = 1.90[/tex]
