Line M passes through the points (-5, 8) and (-1, 9) what is true of line M
Answer:
The equation of the line is:
[tex]y=\frac{1}{4}x+\frac{37}{4}[/tex]Step-by-step explanation:
Given the points
(-5, 8)(-1, 9)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:
[tex]y=\frac{1}{4}x+\frac{37}{4}[/tex]Larry is thinking of a number that is between 0 and 300. What is the correct model for this situation?

If 20 assemblers can complete a certain job in 6 hours, how long will the same job take if the number of assemblers is cut back to 12?
Given,
Total number of assemblers = 20
They work a job in 6 hours.
To find,
Time to complete the work if the number of assemblers is cut back to 12.
Solution,
Initially,
20 assemblers = 6 hours
1 hour = [tex]\dfrac{20}{6}[/tex] assemblers
If assemblers are 12 then,
[tex]t=\dfrac{20}{6}\times 12\\\\=40[/tex]
Hence, 40 hours will be required if the number of assemblers is cut back to 12.
Cylindrical pipe is 2ft. If the pipe is 20ft long what is its volume
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:
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

P partitions GR in ratio 2:4. GR is 36cm. How long is GP and PR?
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
The ratio of dogs to cats at a pet store is 2 to 3 which of the show the possible number of dogs and cats in the pet store
Answer:
See Explanation
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.

A person bought some cosmetics from wholesale market at the rate of Rs 360 per dozen he sells it at Rs 80 a pair find the gain percent pls do it step by step
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%

Which graph shows the points (−112, 12) and (1.5, −0.5) plotted correctly? On a coordinate plane, a point is 0.5 units to the right and 1.5 units up. Another point is 0.5 units to the left and 1.5 units down. On a coordinate plane, a point is 1.5 units to the left and 0.5 units up. Another point is 1.5 units to the right and 0.5 units down. On a coordinate plane, a point is 0.5 units to the left and 1.5 units up. Another point is 0.5 units to the right and 1.5 units down. On a coordinate plane, a point is 1.5 units to the left and 0.5 units down. Another point is 1.5 units to the right and 0.5 units up.
Answer:
Graph 'B' represents the correct graph.
The correct graph is attached below.
Step-by-step explanation:
Let 'A' be the point:
[tex]A\left(-1\frac{1}{2},\:\frac{1}{2}\right)[/tex]Let 'B' be the point:
[tex]B\:\left(1.5,\:-0.5\right)[/tex]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].
As we know that the 2nd quadrant, in the upper left-hand corner, consists of negative values of x and positive values of y.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
As we know that the 4th quadrant, the lower left-hand corner, consists of positive values of x and negative values of y.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.

B

If y is directly proportional with x and
y = 3.6 when x = 30, what is the
value of y when x = 40?
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

Michael is cutting a 100-yard ribbon into pieces 3.4 yards long. He says that an inequality that represents his project is 3.4x 100. Explain what this statement means, in words, and what each part of the inequality represents
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.
A flooring company needs to tile a section of a kitchen that is in the shape of a triangle.
they know that the area is 21 ft squared and the base is 6 ft how can they determine the
height of the triangle?
The formula for the area of the triangle: A = Area B= Base H=Height
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]
