Another salesperson says the ratio in simplest form is 5/24. Which ratio is correct? What error leads to the incorrect ratio?
Answers
Answer:
The ratio that is correct is 5/24.
The error that leads to the incorrect ratio is working with the different units of length.
Step-by-step explanation:
Here is the complete question:
A covered bridge is 8 yards long. In a painting for sale at a gallery, the bridge is 5 feet long. A customer wants to know the ratio of the length of the bridge in the painting to the actual length of the bridge. One salesperson says the ratio in simplest form is 5/8 Another salesperson says the ratio in simplest form is 5/24 Which ratio is correct? What error leads to the incorrect ratio?
Step-by-step explanation:
From the question,
A covered bridge is 8 yards long and in a painting at the gallery, the bridge is 5 feet long.
To determine the ratio of the length of the bridge in the painting to the actual length of the bridge,
First, we will convert both lengths to the same unit and then divide the length of the bridge in the painting by the actual length of the bridge.
Convert 8 yards to feet
1 yard = 3 feet
∴ 8 yards = (8 × 3) feet = 24 feet
The actual length of the bridge is 24 feet
The length of the bridge in the painting is 5 feet
Hence, the ratio of the length of the bridge in the painting to the actual length of the bridge is 5 feet ÷ 24 feet = 5/24
Hence, the ratio that is correct is 5/24.
The error that leads to the incorrect ratio is working with the different units of length (that is, not converting both length to the same unit before determining the ratio).

Step-by-step explanation:
These are the four after 6:4. I didn't know which you needed.
Answer:
3:2
Step-by-step explanation:
If you want to simplify 6:4, it also makes an equivalent equation. To simplify this, we divide by the greatest number that both numbers can be evenly divided by. 6 and 4 can both be divided by 2, which is the biggest number we can divide both numbers by.
6/2=3
4/2=2
The ratio is now simplified/equivalent to 3:2.

identify the slope of the line for the equation 1/6 x + 1/4
Answers
Answer:
y = 1/6x - 8/3
Step-by-step explanation:
The equation of a line in slope-intercept form is.
y = mx + b
where m represents the slope and b, the y-intercept.
Rearrange y + 2 = 1/6 (x - 4) into this form
distribute bracket and simplify.
y + 2 = 1/6x - 2/3
⇒ y = 1/6x - 2/3 - 2
⇒ y = 1/6x - 8/3 ← in slope-intercept form

Which statement is modeled by 2p + 5 < 11
Group of answer choices
The sum of 5 and 2 times p is at least 11
5 added to the product of 2 and p is less than 11
2 times p plus 1 is at most 11
the product of 2 and p added to 5 is 11
Answers
The reason for this is because the inequality multiples 2 and the variable p, which is the product. Then, you have to add 5 to the product of 2p. Since the sign is opened towards the 11, this indicates that the sum of 5 and 2 times p is less than 11. Hope that helps!

To make it easier change the fraction into decimals!
3/8 = .375
5/16 =.3125
7/12 = .583
.5 = 0.5
.25 = 0.25
So, according to my calculations I believe it goes like this: 0.25, 0.375, 0.3125, 0.5, .583
Really I am not sure if this is correct but I hope this helps you understand you can order it whatever way you want but make sure you understand the explanation :) have a great day!!
Felipe and Makayla each tried to solve the same
equation for x.
Original equation: 2x + 6 = 3x - 8
The result of Felipe's first step was -x + 6 = 8.
Describe the first step Felipe made to the equation
Answers
Felipe in the first step shifted 3x from R.H.S. to L.H.S. as -
2x - 3x + 6 = 8
What is a function?
An expression in mathematics defines a relationship between one variable (the independent variable, x) and another variable (the dependent variable, y). For example -
f(x) = 4x + 6
Given is the equation equating two functions as -
2x + 6 = 3x - 8
We have -
2x + 6 = 3x - 8
2x - 3x + 6 = 8
-x + 6 = 8
Therefore, Felipe in the first step shifted 3x from R.H.S. to L.H.S. as -
2x - 3x + 6 = 8

Triangle ABC is translated 5 units to the right and 4 units up to create triangle A'B'C'.
What is the measure of B?
Answers
The measure of the angle B is 74 degrees.
What is the angle sum property?The angle sum property of a triangle states that the sum of the interior angles of a triangle is 180 degrees.
Triangle ABC is translated 5 units to the right and 4 units up to create triangle A'B'C'.
If triangle ABC is translated 2 units up and 2 units right, that means that all the vertices of the triangle are translated by the same units 2 up and 2 right.
The angle sum property of a triangle;
80 + 26 + B = 180
B = 180 - 106
B = 74
Therefore, the size and shape of the triangle wouldn't change.
The triangle A'B'C' will still have the same size and shape, and all the sides will have the same length.
Hence, the measure of the angle B is 74 degrees.

Slove 4(5x-2)= 2(9x+3)
Answers
Answer:
x=7
Step-by-step explanation:
divide both sides by two. distribute on the left side. minus 9x on both sides. add 4 on both sides, and you get 7.
Answer:
x = 7
Step-by-step explanation:
Firstly, use the distributive property to distribute the 4 and the 2 respectively.
[tex]4(5x-2) = 2(9x+3)[/tex]
[tex]20x-8=18x+6[/tex]
Then, isolate the variable. Start by subtracting 18x from both sides.
[tex]2x - 8 = 6[/tex]
Add 8 to both sides.
[tex]2x = 14[/tex]
Divide both sides by 2.
[tex]x=7[/tex]
