Since the scale factor is 4:1, you need to divide each side by 4.
10 / 4 = 2.5
12 / 4 = 3
Also you can clearly rule out answer choices b and c because they just don’t make since since the object is smaller than the scale drawing.

i need to identify the slope and the y-intercept of the line with a given equation, the given equation is y = 1/2x +5 . i need to graph it aswell.
Answers
Answer:
y-intercept: 5
slope: 1/2
Step-by-step explanation:
The equation y=1/2x+5 is an example of y-intercept form(y=mx+b). This is where b represents the y-intercept and m represents the slope. I will not graph this for you but can explain it.
First plot the y-intercept on the graph. (0.5). Then use the slope to find the next point off of the y-intercept. So for example, the next point would be (2,6).

the sum of a number times 4 and 29 is at least 26

Step-by-step explanation:
I'm assuming you want me to make an inequality with this, so I will do that. Since sum means to add, we write this: 4 + 29. At least can translate to greater than or equal to, we can write that symbol as ≥. Now, let's write the whole inequality, we can write it as 4 + 29 ≥ 26.

The seventh grade class is raising money to have a class trip at the end of the year. They began the year with $1500. They now have $1650 in the account. What is the percent of increase for the money the class has raised ?
Answers
Answer:
The percent of the increase for the money the class raised is 10 %
Step-by-step explanation:
Because if you divide 1500 by 10 you get 150 that means 150 is 10 % of 1500 and if you add 150 to 1500 you get 1650 so the increase of money the class raised is 10 %

Triangle DEF is dilated to create triangle DAB. What scale factor was used?
please hurry in less than 10 min
Answers
Answer:
Not sure how you would word it but the bigger triangle is 2 times larger than DEF.
Step-by-step explanation:
DE=4
AE=4
4+4=8
AD=8
Hope this helps!!
The scale factor used to create DAB from triangle DEF is 2.
What are transformations?Two-dimensional figures can be transformed mathematically in order to travel about a plane or coordinate system.
Dilation: The preimage is scaled up or down to create the image.
Reflection: The picture is a preimage that has been reversed.
Rotation: Around a given point, the preimage is rotated to create the final image.
Translation: The image is translated and moved a fixed amount from the preimage.
The length of the base of the triangle DEF is 4 units and of DAB is 8 units.
The length of the height of DEF is 3 units and that of DAB is 6 units.
From this, we conclude that the scale factor is 2 as 8 is a multiple of 2×4 and 6 is a multiple of 2×3.

Example: At a baseball game, Henry bought 3 hotdogs and a bag of chips for $14. Scott bought 2 hotdogs and a
bag of chips for $10. Each of the boys paid the same price for their hotdogs, and the same price for their chips. The
following system of equations can be used to represent the situation. Determine the best method to solve the system
of equations. Then solve the system.
Answers
Answer:
h = $4 a hotdog
c = $2 bag of chips
Step-by-step explanation:
3h + c = 14
2h + c = 10
3h + c = 14
-2h - c = -10
h = $4 a hotdog
2(4) + c = 10
8 + c = 10
c = $2 bag of chips
In a survey of 3,500 people who owned a certain type of car,1,925 said they would buy that type of car again. What percent of the people surveyed were satisfied with the car?
Answers
Answer: percent of the people surveyed that were satisfied with the car= 55%
Step-by-step explanation:
Step 1
Total Number of people in the survey who owned certain type of car = 3,500
Number of people that would buy that type of car again = people surveyed that were satisfied with the car= 1,925
Step 2
Percentage of people satisfied with the car= people surveyed that were satisfied with the car/Total Number of people in the survey who owned certain type of car x 100
=1925 / 3500 x 100
=0.55 x 100
=55%
