What is the slope for these graphs ?

Answer:

y=k*x

plug in the known values of x and y and use them to solve for k

then you can use the new value of k to solve for y when x=40

Answer:

Number of students that use pen= 96

Step-by-step explanation:

Giving the following information:

Ratio pens to pencil= 3:2

First, we need to calculate the proportion of pens and pencils in this middle school:

Pens= 3/5= 0.6

Pencil= 2/5= 0.4

Now, we can determine the number of students that uses pens:

Number of students that use pen= 160*0.6

Number of students that use pen= 96

im 99% sure this is correct

hope this helps <3

Step-by-step explanation:

alright. i calculated each line that is given, and i sadly don't have the time to place them. but, ill still make it easier for u and give the points of each one, and u can place them and see which one is perpendicular and that passes through the given point.

a=(-3,88)

b=(1/3,28)

c=(3,88)

d=(1/3,-12)

i apologize for not having an obvious answer, but hope this helps!

Answer:

12 cm and 24 cm

Step-by-step explanation:

The line is divided in the ratio 2 : 4 = 2x : 4x ( x is a multiplier )

The sum is therefore

2x + 4x = 36

6x = 36 ( divide both sides by 6 )

x = 6

Thus

GP =  2x = 2 × 6 = 12 cm

PR = 4x = 4 × 6 = 24 cm

Answer:

33.3%

Step-by-step explanation:

To get the gain percent, first we need to calculate the unit selling price and cost of each cosmetics.

If a person bought some cosmetics from wholesale market at the rate of Rs 360 per dozen., then one cosmetic will cost 360/12 = Rs. 30

Also if he sells it at Rs 80 a pair, then he sold one cosmetic at 80/2 = Rs. 40

Selling price = Rs. 40

Cost price = Rs. 30

% gain = SP-CP/CP * 100%

% gain = 40-30/30 * 100

% gain = 10/30 * 100

% gain = 100/3

% gain = 33.3%

Hence the percentage gain is 33.3%

Answer:

The equation of the line is:

Step-by-step explanation:

Given the points

Finding the slope between the points

[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]\left(x_1,\:y_1\right)=\left(-5,\:8\right),\:\left(x_2,\:y_2\right)=\left(-1,\:9\right)[/tex]

[tex]m=\frac{9-8}{-1-\left(-5\right)}[/tex]

[tex]m=\frac{1}{4}[/tex]

Using the point-slope form of the line equation

[tex]y-y_1=m\left(x-x_1\right)[/tex]

substituting the values m = 1/4 and the point (-5, 8)

[tex]y-8=\frac{1}{4}\left(x-\left(-5\right)\right)[/tex]

[tex]y-8=\frac{1}{4}\left(x+5\right)[/tex]

Add 8 to both sides

[tex]y-8+8=\frac{1}{4}\left(x+5\right)+8[/tex]

[tex]y=\frac{1}{4}x+\frac{37}{4}[/tex]

Thus, the equation of the line is:

Answer: B. ACCOUNT OWNERS SOCIAL SECURITY NUMBER.

Step-by-step explanation:

4L-30=70

Step-by-step explanation

perimeter of a rectangle =2(L+W)

assuming length =L

with =L-15

p= 2(L+L-15)

p= 4L-30

p=70

therefore equation of the perimeter =

4L-30=70

Answer:

[tex]V=251.32\ ft^3[/tex]

Step-by-step explanation:

The radius of cylindrical pipe, r = 2 ft

Length of the pipe, h = 20 ft

We need to find the volume of the pipe. We know that the volume of the cylinder is given by :

[tex]V=\pi r^2 h\\\\V=\pi \times (2)^2\times 20\\\\=251.32\ ft^3[/tex]

So, the volume of the cylinder is [tex]251.32\ ft^3[/tex].

Answer:

[tex]3.4x\le 100[/tex]

Step-by-step explanation:

Given that,

Michael is cutting a 100-yard ribbon into pieces 3.4 yards long.

Michael says that an inequality that represents his project is 3.4x 100.

Let Michael cuts the ribbon in x no of variables. It is given as :

3.4x is the total length of all the pieces together

i.e.

3.4x is less than or equal to 100.

The required equation that represents the given scanario is :

[tex]3.4x\le 100[/tex]

Answer:

Step-by-step explanation:

Sample Response: The variable, x, is the number of pieces of ribbon Michael cuts. Since each piece is 3.4 yards long, 3.4x is the total length of all the pieces together. This total length cannot be more than the 100 yards of ribbon he has, so 3.4x must be less than or equal to 100.

Step-by-step explanation:

Given

Dogs : Cats = 2 : 3

Required

Determine the possible number of dogs and cats at the store

The question requires options; since there are none, I'll answer on a general terms.

We have the dog to cat ratio to be:

Dogs : Cats = 2 : 3

Multiply ratio by any number (say 7)

Dogs : Cats = 2 * 7 : 3 * 7

Dogs : Cats = 14 : 21

This means that if there are 14 dogs, then there are 21 cats.

Multiply the ratio by another number (say 4)

Dogs : Cats = 2 * 4 : 3 * 4

Dogs : Cats = 8 : 12

This implies:

8 dogs and 12 cats

In conclusion, the number of dogs, when divided by the number of cats must equal ⅔.

Answer: It is possible to determine the height of the triangle by using the formula of the area of a triangle and creating an equation to find the missing value (height). Also, the value of the height is 7ft

Explanation:

The area of a triangle is found by using both the height and the base of a triangle. Indeed, the general formula for this is A( area) = h (height) x b (base) ÷ 2. Now, this general formula can be used to find any of the values missing if two values are known. This means the height can be calculated using the area and the base. To do this, create a simple equation and solve it. The process is shown below:

1. Write the general equation

[tex]A = \frac{h b}{2}[/tex]

2. Replace the letters with the values you have

[tex]21 =\frac{6b}{2}[/tex]

3. Find the missing value by moving the values to the other side of the equal symbol (=) and changing its symbol

21 x 2 = 6b   -For example 2 divided 6b but if it is changed to the other side it needs to multiply

42 = 6 b

42 / 6 = b

b = 7

This means the value of the height is 7 ft. If  you want to double-check this, use the original formula:

A = 6 ft x 7 ft / 2

A= 42 [tex]ft^{2}[/tex] / 2

A= 21 [tex]ft^{2}[/tex]

Step-by-step explanation:

Answer:

SRQ = 66 degrees

Step-by-step explanation:

QRT = 33 degrees

A bisector bisects angles evenly, which means that SRTis also 33 degrees. ADD these two together you get 66 degrees for this angle.

Answer:

<SRQ = 66

Step-by-step explanation:

bisect means to "cut" in half so the line pretty much separates half and half

Answer:

Graph 'B' represents the correct graph.

The correct graph is attached below.

Step-by-step explanation:

Let 'A' be the point:

Let 'B' be the point:

As point A(-1 1/2, 1/2) can be written as:

[tex]A=\left(-\frac{3}{2},\:\frac{1}{2}\right)=\left(-1.5,\:0.5\right)[/tex]

so plotting the point [tex]A=\left(-1.5,\:0.5\right)\:\:\:\:[/tex] and [tex]B\:\left(1.5,\:-0.5\right)[/tex] on a [tex]B\:\left(1.5,\:-0.5\right)[/tex].

Thus, the point A(-1.5, 0.5) will be plotted in the 2nd quadrant at x = -1.5 and y=0.5

i.e. at x= -1.5, y = 0.5

Point B(1.5, -0.5) will be plotted in the 4th quadrant at x = 1.5 and y = -0.5

i.e. at x= 1.5, y = -0.5

Thus, graph 'B' represents the correct graph.

The correct graph is attached below.
