Answer:

The second graph is the answer

Step-by-step explanation:

Answer:

x = 7

Step-by-step explanation:

10 / 4 = x + 8 / x - 1

[cross multiply]

10 (x - 1) = 4 (x + 8)

[distribute the factors]

10x - 10 = 4x + 32

+ 10 + 10

[add 10 to both sides to cancel out -10]

10x = 4x + 42

-4x -4x

[subtract both sides by 4x to cancel out 4x]

6x = 42

÷6 ÷6

[divide both sides by 6 to simplify 6x to x]

x = 7

________

x = 7 → 10 / 4 = x + 8 / x - 1 →

(7) + 8 / (7) - 1 → 15 / 6 →

15 ÷ 3 / 6 ÷ 3 → 5 / 2 →

5 × 2 / 2 × 2 → 10 / 4 = 10 / 4

Answer: Printer A can print (576/48) 12 pages per minute. Printer B can print (1104/48) 23 pages per minute

Step-by-step explanation:

Answer:

Printer A 576/48 = 12

Printer B 1104/48 = 23

23-12 = 11

Therefore Printer B can print 11 more pages than Printer A

Answer:

x = 33

Step-by-step explanation:

Sum of the interior angles of a 5-sided polygon = 540°

Therefore all the interior angles of the given polygon would all be equal to 540°.

Thus:

(4x - 25)° + (3x + 25)° + (2x - 3)° + (4x)° + (3x + 15)° = 540°

Solve for x

4x - 25 + 3x + 25 + 2x - 3 + 4x + 3x + 15 = 540

Combine like terms

4x + 3x + 2x + 4x + 3x - 25 + 25 - 3 + 15 = 540

16x + 12 = 540

16x = 540 - 12

16x = 528

Divide both sides by 16

Answer:

First Angle: 45 degrees, Second Angle: 80 degrees, Third Angle 55 degrees

Step-by-step explanation:

180∘= x+ 2x-10∘+ x+10

180∘=4x

x=45∘

2x-10=80∘

x+10=55∘

The measure of the interior angles of the triangle are 45°, 80° and 55°

respectively.

A triangle is a three-sided closed-plane figure formed by joining three noncolinear points. Based on the side property triangles are of three types they are Equilateral triangle, Scalene triangle, and Isosceles triangle.

We know the sum of all the interior angles in a triangle is 180°.

Given, a triangle has interior angles x°, (2x - 10)° and (x + 10)°.

∴ x + (2x - 10) + (x + 10) = 180°.

4x = 180°.

x = 45°.

Answer:

69°

Step-by-step explanation:

180 - 21 -90 = 69

hope this helps...

Answer: The missing angle is 69°

Step-by-step explanation: When all the angles have their vertex on a straight line, they must add up to 180° They are "supplementary" angles.

The "box" in the corner of an angle is a symbol for "right angle" so that is a way to have a "given" 90°

Knowing that, you can add the "given" 90° + 21° to get 111°

Subtract 111° from 180° to find Angle a:

180 - 111 = 69

Answer:

$9,247.20

924,720 cents

Step-by-step explanation:

The computation of the amount of the income tax is shown below:

In dollars

= Annual income × rate of income tax

= $154,120 × 6%

= $9,247.20

Now in cents, it would be

= Annual income × rate of income tax × 100

= $154,120 × 6% × 100

= 924,720 cents

Answer:

45

Step-by-step explanation:

Like last question an isosceles has two angles that are the same. The square indicates a right angle so h=90

180-90=90

90/2=45 so G and E equal 45

Because you are given that one angle measures 90 degrees, this is an isosceles right triangle. Therefore, the other two angles must be equal, and  add up to 90 degrees because an isosceles right triangle is exactly half of a square. Also, all angles in a triangle must add up to 180 degrees. Because of these rules, we can completely ignore the expression for angle G and sufficiently say it is 45 degrees.

Here

[tex](x_1, y_1)=(-7,-4) \ and \ m=-\frac{2}{3}[/tex]

Answer:

Option D The pattern is multiplicative because the earnings are 12 times the number of hours worked in each pair of values is correct option.

Step-by-step explanation:

At x-axis we have number of hours worked and y-axis represents earnings in dollars.

We can make the table:

Number of hours worked (x)         earnings in dollars (y)

1                                                                12

2                                                               24

3                                                               36  

4                                                               48

5                                                                60

Now, we need to find the pattern.

If we add 1+ 11 we get 12, but if we add 2+ 11 we get 13 and not 24 so, the pattern is not additive.

Now, if we multiply 1 by 12 (1 x 12) we get 12,

then 2 x 12 = 24

3 x 12 = 36

4 x 12 = 48

and 5 x 12 = 60

The same number if multiplied with x-axis we get y-axis.

So, the pattern is multiplicative. and we are multiplying 12 with the number of hours worked, so the correct option is option D.

Option D The pattern is multiplicative because the earnings are 12 times the number of hours worked in each pair of values is correct option.
