A copy shop charges $0.20 per photocopy for orders of up eight copies. Which graph represents this relation? ​

Answer:

x = 15

Step-by-step explanation:

Angle Formed by Two Secants = 1/2(DIFFERENCE of Intercepted Arcs)

2x +15 = 1/2 (10x+20 - 80)

Multiply by 2

4x+30 = (10x+20 - 80)

Combine like terms

4x+30 = 10x-60

Subtract 4x from each side

30 = 6x-60

Add 60 to each side

90 =6x

Divide by 6

15 =x

Answer:

99.4%

Step-by-step explanation: 2500 - 15 = 2485

2485/2500 = 0.994 x 100 = 99.4%

Answer:

99.4%

Step-by-step explanation:

Total number of people tested = 2500

People who had allergic reaction = 15

People who didn't have allergic reaction = 2500 - 15 = 2485

Percentage = Part of a whole / The whole

=> 2485 / 2500

=> 497 / 500

=> .994

To convert a decimal into percent:

=> We need to make the decimal point move 2 times to the right

=> .994

=> 99.4%

So, 99.4% of the people who were tested, didn't have an allergic reaction.

Answer:

Step-by-step explanation:

The measure of right angle is 90°

The sum of measures of angles in any triangle is 180°

so:

m∠Q + m∠S + ∠R = 180°

m∠Q + m∠S + 90° = 180°

m∠Q + m∠S = 180° - 90°

m∠Q + m∠S = 90°

In right triangle QRS with ∠R = 90° , the sum of m ∠Q and m ∠S must be equal to 90°.

"Right triangle is defined as the two dimensional figure with three sides and three vertices and angles enclosed in it, with one of the interior angle is of 90°."

Condition used

In ΔQRS

∠Q +  ∠R + ∠S = 180°

According to the question,

Given,

In right triangle ΔQRS,

∠R = 90°

Substitute the value in the above condition of triangle we get,

  ∠Q + 90° + ∠S =180°

⇒ ∠Q + ∠S =180°- 90°

⇒∠Q + ∠S = 90°

Hence, in right  triangle QRS with ∠R = 90° , the sum of m ∠Q and m ∠S must be equal to 90°.

Step-by-step explanation:

From the figure we observe :

Length of laundry room (G) = C - H

G = (4x - 2) - (x + 6) = 3x - 8

Breadth of laundry room (F) = K - E

F = (2x - 5) - (x - 13) = x + 8

(A) Perimeter = 2(L + B)

= 2(4x)

= 8x

(B) Area = L * B

= (3x - 8) * (x + 8)

= 3x^2 + 16x - 64

Answer:

x = 0

Step-by-step explanation:

two congruent angles 2x + 30 and 5x + 30

2x + 30 = 5x + 30

2x = 5x

2x + (-5x) = 5x + (-5x)

-3x = 0

x = 0 / -3

x = 0

The value of x will be;

⇒ x = 0

A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.

Given that;

Two angle in a triangle 2x+30 degree and 5x+30 degree are congruent.

Now,

Since, Two angle in a triangle 2x+30 degree and 5x+30 degree are congruent.

Hence, We get;

⇒ 2x + 30 = 5x + 30

Solve for x as;

⇒ 30 - 30 = 5x - 2x

⇒ 0 = 3x

⇒ x = 0

Thus, The value of x = 0

Explanation:

The middle coefficient is -4 and the last term is 4.

We need to find factors of the last term that add to the middle coefficient.

Here is a list of all ways to multiply two integers to get 4, and the sum of each pair of factors.

The second row of that list above is what we're after. So

-2 + (-2) = -4

-2 * (-2) = 4

Meaning the factorization is (x-2)(x-2). Note the "-2" values in each factor

We can use the FOIL rule or distribution to go from (x-2)(x-2) back to x^2-4x+4 to confirm the answer.

Answer:

The total cost C  = $10 + $0.05·x

Step-by-step explanation:

The given parameters are

The cost of the cell phone plan per month = $20

The number of minutes of free calls that one can make in a month = 200 minutes

The cost of additional minutes of cell phone call = 5 cent

5 cents to a dollar = $0.05

The total number of minutes of calls made in a month = x

The time duration of a person's usage of the cell phone in a month > 200 minutes

The total cost C of a person's usage per month is given by;

C = $20 + $0.05 × (x - 200) = $20 + 0.05·x - $10

C = $10 + $0.05·x

Step-by-step explanation:

Pearson correlation coefficient represented by r is calculated by dividing  the covariance by the standard deviation of one variable(x) multiply by the standard deviation of the other variable(y).

A scatter plot diagram is a graphical display of data that in which these two variables are observed simultaneously.

A positive correlation is said to have a positive slope which means that the two variable x and y increases in x as there is increase in y.

On the other hand , when there is an increase in x and a decrease in y, the correlation between x and y is said to be negative and the corresponding regression line has a negative slope.

Occasionally, there may be no apparent association between x and y. In that wise, the data in the scatter plot diagram usually form a nearly perfect circle and are said to have a zero correlation.

Answer:

AB = 10.6 cm

Step-by-step explanation:

In triangle FGH, FG = 12.3 cm, GH = 10.6 cm, m angle G=80 degrees, and m angle H=55 degrees. If triangle ABC GHF, which statement is true?

A. AB = 12.3 cm

B. AB = 10.6 cm

C. M angle C=55 degrees

D. M angle C=80 degrees

Answer:

If triangle ABC ≅ GHF, This means triangle ABC is congruent to triangle GHF.

Two triangles are congruent if the three sides and three angle of one triangle is equal to the three sides and three angle of the other triangle.

Hence the corresponding sides and angles of triangle FGH is equal to the corresponding side and angle of triangle ABC.

AB = GH

AB = 10.6 cm

m∠F + m∠G + m∠H = 180° (sum of angles in a triangle)

m∠F + 80 + 55 = 180

m∠F + 135 = 180

m∠F = 180 - 135 = 45

m∠F = 45°

m∠F = m∠C

m∠C = 45°

Start by changing the problem to 3x + 8 + -5x + 10.

Combine like terms → your numbers and your "x" terms.

So 3x + -5x is -2x and 8 + 10 is 18.

So the answer is -2x + 18.

1.625

Step-by-step explanation:

So you have to convert the 5/8ths into something that can go into 10.

So 100/8 is equivalent to 12.5. But you'll have to make that into decimal form, so move that 2 places to the right, to get 0.125. 0.125 times 5 is 0.625. And 1 is just 1 as a whole number. 1 plus 0.625 is 1.625.

The decimal form of the given number [tex]1\frac{5}{8}[/tex] is 1.625

In Algebra, decimals are one of the types of numbers, which has a whole number and the fractional part separated by a decimal point.

Given is a fractional number  [tex]1\frac{5}{8}[/tex], we need to find the decimal form of it,

Converting  [tex]1\frac{5}{8}[/tex] into fraction,

[tex]1\frac{5}{8}[/tex] = 13/8

When we divide 13 by 8, we will get 1.625

Hence, the decimal form of the [tex]1\frac{5}{8}[/tex] is 1.625
