Answer:
We want to get y and x such that it satisfices all geometric relations:
3y=87
y=87/3 = 29 degree
Hence y= 29 degree
Two parallel lines tell us that 87=3x such that x=29

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
Step-by-step explanation:
cuz cuz you need it to be directly that's what you need to
the ratio of pens to pencils that are used by Woodlands middle school students is 3 to 2 if their is a total of 160 middle school students how many of them use pencils
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

Step-by-step explanation:
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]
What’s the missing length????? Please

The missing length is 11
Step-by-step explanation:
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.

Answer:
Value of X = 100°
Step-by-step explanation:
Given:
∠ A = 70°
∠ D = 115°
∠ C = X + 10°
Find:
Value of X
Computation:
In cyclic quadrilateral ∠ A + ∠ C = 180°
So,

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]Could someone help this is hard to me
Answer:
[tex]\frac{4}{8}[/tex] = [tex]\frac{x-2}{x+3}[/tex] ( set the two triangles proportional to each other)

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%

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].

What should be done to both sides of the equation in order to solve y + 8.5 = 17.2?
Add 8.5.
Subtract 17.2.
O Add 17.2.
Subtract 8.5.
Answer:
Subtract 8.5
Step-by-step explanation:
To solve the equation, y has to be isolated (only y will be on one side of the equation)
To do this, we have to get rid of the 8.5, so it has to be subtracted from both sides.
So, the correct answer is subtract 8.5
Subtract 8.5 from both sides to solve equation.
What is a expression? What is a mathematical equation?A mathematical expression is made up of terms (constants and variables) separated by mathematical operators. A mathematical equation is used to equate two expressions.A mathematical equation is used to equate two expressions. Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.We have the following equation -
y + 8.5 = 17.2
y + 8.5 - 8.5 = 17.2 - 8.5
y = 8.7
Therefore, Subtract 8.5 from both sides to solve equation.
