A store bought pants at a wholesale price of $15. They retail the pants for $45. What is the amount of change? What is the percent increase?

Answer:

y= 4/5x +2/5

Step-by-step explanation:

When finding slope, use the format y-y1/x-x1. Plug in your coordinates to get this: 8-4/2--3. 8-4 equals 4, and 2--3 equals 5. So, your slope would be 4/5. Next, make your equation like this: y=4/5x+b. Next, plug in one of your ordered pairs into the equation. It doesn't matter which one you use. I'm going to use the second pair, so it would look like this: 8=4/5(2)+b. Multiply 4/5 by 2 to get 8/5. This is what you should have: 2=8/5+b. Subtract 8/5 from both sides to get your y-intercept of 2/5. Go back to your original equation and plug in 2/5 to b. This is your final equation: y= 4/5x +2/5. Hope this helped!

Answer:

The value of a is -2

Step-by-step explanation:

We are asked to give the value of a

We are provided with some information

We are given slope to be 4

And two points ( -1 ,-1) and

( a, -5)

Given the formula for slope

m = y_2 - y_1 / x_2 - x_1

Points ( -1 , -1)

(a, -5)

x_1 = -1

y_1 = -1

x_2 = a

y_2 = -5

Inserting the values given into

m = y_2 - y_1 / x_2 - x_1

= -5 - (-1) / a - (-1)

= -5 + 1 / a + 1

= -4 / a + 1

We are given the slope to be 4

i. e. m = 4

4 = -4 / a + 1

Cross multiply

4( a + 1) = -4

Open the bracket with 4

4a + 4 = -4

Collect like terms

4a = -4 - 4

4a = - 8

Divide both sides by 4 to get the value of a

4a / 4 = -8/4

a = -2

Therefore, x_2 = -2

the value of a = -2

Answer:

1.)x≤9

2.)x≥0.5

Step-by-step explanation:

1.)x+6≤15

x+6-6≤15-6

x≤9

2.)x+1.5≥2

x+1.5-1.5≥2-1.5

x≥0.5

Solution:

Given that,

A value of 500 increases by 12%

To find: equation could be used to find the new value

Therefore,

Initial value = 500

Increase rate = 12 %

Let "y" be the new value

Thus the equation is:

new value = Initial value + 12 % of Initial value

[tex]y = 500 + 12 \% \text{ of } 500\\\\y = 500 + 12 \% \times 500\\\\y = 500(1 + 12 \%)\\\\y = 500(1 + \frac{12}{100})\\\\y = 500( 1 + 0.12)\\\\y = 500(1.12)[/tex]

Thus the equation is found. Option B is correct

Solve it

[tex]y = 500 \times 1.12\\\\y = 560[/tex]

Thus the new value is 560

Answer:

volume = 150.9m³

Step-by-step explanation:

in order to find  the volume ,in cubic meter ,of a cylinder with a height of 3 meters and a base radius of 4 meters ,to the nearest theths place wee apply the formular for finding the volume of a cylinder which is πr²h

v =  πr²h

given that

height = 3meters

radius = 4meters

volume=?

going by the formulae v= πr²h

v = π × (4)² × 3

v = π × 16 ×3

v= 48πm³

note the value of π = 22/7

v = 48 × 22/7

v = 1056/7

v= 150.87m³

therefore the volume of the cylinder to the nearest tenth place is 150.9m³

The value of x in the right-angle triangle is 2√3.

A triangle is also known as a right-angled triangle if one of its three angles is 90 degrees. A right-angled triangle's three interior angles all add-up to 180 degrees, thus if one angle is always 90 degrees, the other two must also always add up to 90 degrees.

In the given figure,

BC = 6cm

DC = 6/2 = 3cm

By formula of angle on a straight line,

∠EDB = 180° - (90°+60°)

= 180° - 150°

= 30°.

From right-angled triangle ADC,

AD² = 5² -3² (As per Pythagoras theorem)

= 25 - 9

= 16.

So, AD = √16

= 4cm.

From ∠AEC. let AS = x.

w/Sin60° = 4/Sin90°

We know,

Sin90° = 1

Sin60° = √3/2

⇒ x = (4 × Sin60°)/Sin90°

⇒ x = 4 × √3/2

⇒ x = 2√3

The area of the (ring) - the shaded region is 75.36 in²

Solution:

The value of π = 3.14

Radius of the inner circle = 5 in

Area of the inner circle = πr²

                                       = π × 5²

Area of the inner circle = 25π

Radius of the outer circle = (5 + 2) = 7 in

Area of the outer circle = πr²

                                       = π × 7²

Area of the outer circle = 49π

Area of the shaded ring = Area of the outer circle – Area of the inner circle

                                        = 49π – 25π

                                        = 24π

                                        = 24 × 3.14

                                        = 75.36 in²

The area of the (ring) - the shaded region is 75.36 in².                                

Answer:

1. The cost of 7 gallons of milk is $15.75

2. 5 cups served and 40 ounces drank

Step-by-step explanation:

Answer:

$15.75

Step-by-step explanation:

Let the cost of 7 gallons of milk be x

Since

3 gallons of milk = $6.75

7 gallons of milk = x

Cross multiply

7 x 6.75 = 3 x X

47.25 = 3x

Divide both sides by 3

47.25/3 = 3x/3

15.75 = x

x = $15.75

7 gallons of milk cost $15.75

The diameter of the circle is 10.8 cm

The circumference of the circle is 33.9 cm

Explanation:

Given that the radius of the circle is 5.4 cm

Diameter:

The diameter of the circle can be determined using the formula,

[tex]d=2r[/tex]

where r = 5.4

Thus, we have,

[tex]d=2(5.4)=10.8[/tex]

Thus, the diameter of the circle is 10.8 cm

Circumference:

The circumference of the circle can be determined using the formula,

[tex]C=2\pi r[/tex]

Substituting [tex]\pi=3.14[/tex] and [tex]r=5.4[/tex], we have,

[tex]C=2(3.14)(5.4)[/tex]

[tex]C=33.9[/tex]

Thus, the circumference of the circle is 33.9 cm

g = 6

Step-by-step explanation:

Calculate the slope m using the slope formula and equate to 2

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (10, g) and (x₂, y₂ ) = (9, 4)

m = [tex]\frac{4-g}{9-10}[/tex] = [tex]\frac{4-g}{-1}[/tex] = 2 ( multiply both sides by - 1 )

4 - g = - 2 ( subtract 4 from both sides )

- g = - 6 ( multiply both sides by - 1 )

g = 6

The most reasonable prediction of the number of seventh-grade students in Judith's school who would choose pop music as their favorite genre is 205.

To find the prediction, we first need to determine the total number of seventh-grade students in Judith's school. Since 41 students represent 20% of the total, we can set up a proportion to find the total number of students. Let [tex]\( T \)[/tex] represent the total number of students.

[tex]\[ 20\% \times T = 41 \][/tex]

[tex]\[ 0.20 \times T = 41 \][/tex]

To find [tex]\( T \)[/tex], we divide both sides of the equation by 0.20:

[tex]\[ T = \frac{41}{0.20} \][/tex]

[tex]\[ T = 205 \][/tex]

Now that we have the total number of students, we can predict the number of students who would choose pop music as their favorite genre. Since 41 students represent 20% who chose pop music, the remaining 80% of the students would also be expected to choose pop music if the sample is representative of the entire population. Therefore, we multiply the total number of students by 100% to find the prediction:

[tex]\[ \text{Prediction} = T \times 100\% \][/tex]

[tex]\[ \text{Prediction} = 205 \times 1 \][/tex]

[tex]\[ \text{Prediction} = 205 \][/tex]

Thus, the most reasonable prediction is that 205 seventh-grade students in Judith's school would choose pop music as their favorite genre.

well, the distance from the center of a circle to any point "on" the circle is simply just its radius, thus

Final answer:

The equation of the circle with center (11, 6) that passes through the point (17, 12) is (x - 11)² + (y - 6)² = 72.

Explanation:

To find the equation of the circle with center (11, 6) that passes through the point (17, 12), we first determine the radius of the circle. The radius can be found by calculating the distance between the two points using the distance formula: √[(x2-x1)² + (y2-y1)²]. Plugging in the coordinates, we get √[(17-11)² + (12-6)²] = √[6² + 6²] = √[36 + 36] = √72. The squared radius (r²) is therefore 72.

The general form for the equation of a circle is: (x - h)² + (y - k)² = r², where (h, k) is the center of the circle. Substituting the center (11, 6) and the squared radius 72 into this equation, we get: (x - 11)² + (y - 6)² = 72, which is the desired equation of the circle.
