What is the slope and the y- intercept of the line on the graph

Answer:

Step-by-step explanation: To find the mean of the dot plot, you will need to add all of the dots together.

For example: Above 2, there are 3 dots , so you would need to multiply 2 by three to get 6 dots above the number 2.

Do that for all of the numbers on the dot graph from 1 - 6, and you will have this equation:

1 + 6 + 18 + 20 + 15 + 12

Next, you will need to add all those numbers together and you will get 72.

Lastly, divide by how many numbers there are, and there are 6 numbers.

So, that will be 72/6 which is 12.

Your answer will be 12.

Answer:

  a) h/2

  b) r/√2 = (r√2)/2

Step-by-step explanation:

a) The volume of a cone is proportional to height. If the volume is halved, then the height will be halved.

The new height will be h/2.

__

b) The volume is proportional to the square of the radius. If the volume is halved, the square of the radius is halved. The new radius will be ...

  (r')² = r²/2

  r' = r/√2 = (r√2)/2 . . . radius of half-volume cone

Answer:

x = 15°

x = 135°

x = -45°

x = -180°

Step-by-step explanation:

Trigonometric Equations

Solve

cos(2x + 30°) = 0.5 for -180° ≤ x ≤ 180°

Applying the inverse cosine function:

2x + 30° = arccos(0.5)

There are several angles whose cosine is 0.5. They are 60°, 300°, -60° and -300°, thus we have these candidate solutions:

2x + 30° = 60°

2x + 30° = 300°

2x + 30° = -60°

2x + 30° = -300°

Subtracting 30° to all the equations:

2x = 60° - 30° = 30°

2x = 300° - 30° = 270°

2x = -60° - 30° = -90°

2x = -60° - 300° = -360°

Dividing by 2 we have the complete set of solutions:

x = 15°

x = 135°

x = -45°

x = -180°

Answer:it would be 15 quarters and 10 dimes

Step-by-step explanation:

15 quarters is 3.75 and 10 dimes is $1, add them up you get $ 4.75

Answer:

15 quarters and 10 dimes

Step-by-step explanation:

25x + 10(25-x) = 475

x = 225/15

x = 15

So that has to mean he has 10 dimes

Answer: $277.99

Step-by-step explanation:

There are 52 weeks in a year. Assuming the architect would get paid every week, you would divide their salary by 52.

14,455.32/52 = 277.9869

Rounding to two decimal places, the answer would be $277.99.

Answer:

301.15

Step-by-step explanation:

Answer:

Step-by-step explanation:

Area of a rectangular plot = Length × width

With the aid of the diagram attached below.

For plot 1:

The area = ( 60 - 20 ) × ( 80 - 20 )

Area = 40 × 60

Area = 2400 sq yard

For plot 2:

Area = (160 - 120 ) × ( 180 - 120 )

Area = 40 × 60

Area = 2400 sq yard

Therefore, the combined area of the two plots of land = 2400 + 2400

= 4800 square yards

Answer:

J. 108°

Step-by-step explanation:

m<EDF = 180 - 148 = 32° (angles on a straight)

m<EFD = 180 - 140 = 40°(Angles in a straight line)

m<DEF = 180 - (m<EDF + m<EFD) (sum of triangle)

m<DEF = 180 - (32 + 40)

m<DEF = 180 - 72

m<DEF = 108°

144 = 12² = (3 x 4)²

Answer:

The inequality the graph has shown is y < 2x - 3 ⇒ C

Step-by-step explanation:

The form of the linear equation is y = m x + b, where

From the given figure

∵ The line drawn is a dashed line

→ That means the sign of inequality without the equal sign

∴ The sign of the inequality is without the equal sign

∵ The shaded area is under the line

→ That means the sign of the inequality is smaller than

∴ The sign of the inequality is <

∵ The line intersects the y-axis at point (0, -3)

→ That means the y-intercept is -3

∴ The y-intercept = -3 ⇒ (value of b in the equation of the line)

∵ There is only one answer has sigh < and y-intercept -3

∴ The inequality the graph has shown is y < 2x - 3

Answer:

$0.90

Step-by-step explanation:

1 quart = 2 pints

Write a proportion:

$1.80 / 4 pint = x / 2 pint

Cross multiply:

4x = 3.60

Divide:

x = 0.90

The price per quart is $0.90.

Answer:

4-quart carton of fruit punch for $2.08

Step-by-step explanation:

4-quart carton of fruit punch for $2.08

2.08 : 4 = 0.52

check your work:  0.52 x 4 = 2.08

so for the first offer you will be paying $0.52 per quart .

4-cup carton of fruit punch for $0.80

1 cup = 0.25 quarts

4 cups = 1 quart

0.80 : 1 = 0.80

for the second offer you will be paying $0.80 per quart of fruit punch. 4-quart carton of fruit punch for $2.08 is a better buy because you will be paying for each quart than in first offer.

Answer:

45°

Step-by-step explanation:

First, find the measure of each interior angle of the octagon.

Measure of each interior angle of the octagon = [tex] \frac{(n - 2)180}{n} [/tex]

Where, n = 8.

Plug in the value of n into the formula

[tex] = \frac{(8 - 2)180}{8} [/tex]

[tex] = \frac{(6)180}{8} [/tex]

[tex] = \frac{1,080}{8} = 135 [/tex]

x = 180 - 135 (straight line theorem.)

x = 45°

Step-by-step explanation:

each 20m miles takes 1g gallon.

Answer:

[tex]y=-\frac{1}{20} x + 20[/tex]

Step-by-step explanation:

The slope equation is always [tex]\frac{rise}{run}[/tex]. In this case, the gallons went down by 1- so we can call the rise -1. When it went down by 1, the miles went up by 20- so we can call the run 20. This gives us a fraction (the "m" value) to put in the slope equation [tex]y=mx+b[/tex]. To find the y intercept (the "b" value), you find out what y is when x = 0, which is given in the chart: 20.
