Guina made a scale drawing of a window she is making for her house.
1 centimeter = 3 inches. Triangle A B C. Side A is 4 centimeters, side B is 3 centimeters, and side C is 5 centimeters.
Which proportion could Guina use to find the length of side B?
StartFraction 1 centimeters over 3 inches EndFraction = StartFraction 3 centimeters over x centimeters EndFraction
StartFraction 3 centimeters over 1 centimeter EndFraction = StartFraction x centimeters over 3 centimeters EndFraction
StartFraction 1 centimeter over 3 inches EndFraction = StartFraction 3 centimeters over x inches EndFraction
StartFraction 3 inches over 3 centimeters EndFraction = StartFraction x inches over 1 centimeter
Answer:
Proportion: 1/3=3/x
Step-by-step explanation:
The "1/3" proportion is telling us how the scale measurement relates to the real measurement.
The "3/x" describes the length of side B.

Write in point slope form an equation of the line that passes through the given point and has the slope. (-2, 9) and m = 5
Answer:
The point-slope form of an equation of the line is:
[tex]y-9 = 5(x+2)[/tex]
Step-by-step explanation:
Given
Slope m = 5
Point (-2, 9)
Point slope form of an equation of a line:
Point slope form of an equation of a line is defined as
[tex]y-y_1=m\left(x-x_1\right)[/tex]
where
m is the slope of the line(x₁, y₁) is the pointIn our case,
m = 5(x₁, y₁) = (-2, 9)substituting the values m = 5 and the point (x₁, y₁) = (-2, 9) in the point-slope form of the line equation
[tex]y-y_1=m\left(x-x_1\right)[/tex]
[tex]y - 9 = 5 (x - (-2)[/tex]
[tex]y-9 = 5(x+2)[/tex]
Therefore, the point-slope form of an equation of the line is:
[tex]y-9 = 5(x+2)[/tex]

tom's garage is 12 feet tall and 20 feet wide. he wants to build a scale model of his garage for his sons play cars. tom wants the scale model to be 9 inches tall. how wide should the scale model be
Answer:
15 inches
Step-by-step explanation:
12 inches = 1ft
12ft = 144 inches
144/9 = 16
20ft = 240 inches
240/16 = 15 inches
Tom wants the scale model to be 9 inches tall, the width of the scale model should be 15 inches.
What is scale model?A scale model is a physical representation of an object that maintains the proportions and relative sizes of the original object.
First, we need to determine the scale factor that will be used to create the model.
We can do this by converting the height of the real garage from feet to inches and dividing it by the desired height of the model in inches:
12 feet = 12 x 12 = 144 inches
scale factor = 144 / 9 = 16
This means that every dimension of the model will be 16 times smaller than the actual dimensions of the garage.
To find the width of the scale model, we need to take the actual width of the garage and divide it by the scale factor:
20 feet = 20 x 12 = 240 inches
240 / 16 = 15 inches
Thus, the width of the scale model should be 15 inches.

Chris is tiling the bathroom floor. For a tile to fit in the corner of the room, he must cut it as shown below.
If x = 3, y = 12, and z = 9, what is the area of the tile being used?
A.
54 sq ft
B.
108 sq ft
C.
58.5 sq ft
D.
81 sq ft
Answer:
D. 81 sq. ft.
Step-by-step explanation:
We know x, y, and z's lengths. Those are 3, 12, and 9 respectively.
I first imagined a 12 by 9 rectangle and then figured about the area of the shaded part.
The 12 by 9 rectangle is 108 sq ft, But there is a empty part on the top left. That would be a 9 ft by 6 ft triangle.
The area of a triangle can be figured out with this formula: A = bh/2 Substitute b and h for 9 and 6 respectively.
A = (9 * 6)/2
A = 54/2
A = 27 sq. ft.
Now, subtract 27 from 108 to get the area of the shaded part.
108 - 27
81 sq. ft.
The area of the tile being used is 81 sq. ft.

what expression is equivalent to 8x-12y+32?
Answer:
divide all terms by same numeral
Step-by-step explanation:
4x-6y+16
2x-3y+8
Answer:
The answer is C. 16(0.5x-0.75y+2)
Step-by-step explanation:
I just got it correct on e d g e n u i t y!!!!!!!!!!!!!!!!!
Also the math the do it is this. Take the first answer for example. because of the parentheses you are going to take the number out side of the parentheses and multiply it by the numbers that are in the parentheses. So lets apply this.
1st Example... 16(0.5x-4y+32)
16 * 0.5x (When using a calculator just put in 16*0.5) The answer is 8 add on the x so it is 8x. 16*4y= 64y 16*32= 512. Then when you add symbols in you turn out with an answer for 1 that should look like this... 8x-64y+512 That is not equivalent to 8x-12y+32. So this is not the correct answer. (Because it isn't equivalent)
2nd Example... You can narrow down the search and make it easier if you do this... There is still a 32 in it and multiplying 32 and 16 will always equal 512 so you know it is not the second answer.
3rd Example... The third example Is correct because 1 all the other answers aren't lol. and 2 because the math steps are correct I will show you. 16(0.5x-0.75y+2) 16*0.5x=8x 16*0.75y=12y (looking pretty good!!) 16*2= 32!!
So in an equation it looks like this... 8x-12y+32 Thus leading us to the answer that the third option(Option C. ) Is correct!!
4th Example... This can not be correct because you are looking for an answer with 12y and 4y*16 will always equal 64y so it cannot be this answer.
KEY= * is the times symbol!!
Also if you want to right great answers like this put in an extra little bit of effort to learn the material and you will be golden in no time at all!!!

Isabella is deciding between two parking garages. Garage A charges an initial fee of
$4 to park plus $3 per hour. Garage B charges an initial fee of $12 to park plus $2 per
hour. Let A represent the amount Garage A would charge if Isabella parks for t
hours, and let B represent the amount Garage B would charge if Isabella parks for t
hours. Write an equation for each situation, in terms oft, and determine the hours
parked, t, that would make the cost of each garage the same.
Answer:
i. A = 4 + 3t .......... 1
B = 12 + 2t .......... 2
ii. The hours required would be 8 hours.
Step-by-step explanation:
The charges at each of the garages can be expressed as;
i. For garage A,
A = 4 + 3t .......... 1
ii. For garage B,
B = 12 + 2t .......... 2
where A is the amount charged at garage A, B is the amount charged at garage B, and t is the number of hours.
To determine the number of hours parked that would make the cost of each garage the same.
Let:
equation 1 = equation 2
4 + 3t = 12 + 2t
collect like terms
3t - 2t = 12 - 4
t = 8
The hours that would make the cost of each garage the same is 8 hours.

A won a race at the local fair by running 10.5 miles in exactly 2 hours. At this constant rate, how long does it take the same dog to run the 21 mile state fair race? Use ratio reasoning to solve. * 1 point
Answer:
The dog will run the 21-mile race in 4.04 hours
Step-by-step explanation:
The first thing we need to do is find out how far he ran the race at the local fair in 1 hour.
To do this, we can set up a simple relationship:
If he ran 10.5 miles in 2 hours,
He will run x miles in 1 hour
Cross multiplying, we have
x = (10.5 X 1)/2 = 5.25 miles in 1 hour.
We can now comfortably say that he runs at the rate of 5.2miles/hr
He now goes to the state fair race, which is 21 miles long.
if he runs at the rate of 5.2 miles in 1 hour,
He will run 21 miles in y hours
y = 21 / 5.2 = 4.04 hours
The dog will run the 21-mile race in 4.04 hours
