Ruby says that 4/5 divided by 2/15 = 14/15. What error did Ruby make? A. Ruby added instead of divided. B. Ruby divided 2/15 by 4/5 instead of 4/5 by 2/15. C. Ruby divided by 2 instead of dividing by 2/15. D. Ruby multiplied by 2/15 instead of 15/2 multiplying by .
Answer:
A. Ruby added instead of divided
Step-by-step explanation:
You must find a common denominator (15), and then multiply by the reciprocal and simplify your final answer
12/15 times 15/2 equals 180/30 which, when simplified equals 6
Ruby added 4/5 and 2/15 instead of dividing. Option A is correct.
What is simplification?Using mathematical operations it is to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
here,
Ruby says that 4/5 divided by 2/15 = 14/15, which is incorrect.
4 / 5 divided by 2/15 is 6,
When we add both numbers,
= 2 / 15 + 4 / 5
= [2 + 12] / 15
= 14 / 15
Thus, Ruby added 4/5 and 2/15 instead of dividing. Option A is correct.

Last year Ron bought 40 pen sets and sold 25. This year he bought 75 pen sets and sold 60. The absolute error each year was the same. Are the percent errors also the same? Explain using the solutions.
Answer:200
Step-by-step explanation:
Answer:
No, differentStep-by-step explanation:
Last yearBought 40 sets
Sold 25 sets
Error = 25 - 40 = -15Absolute error = | - 15| = 15Percent error = 15/40*100% = 37.5%This yearBought 75 sets
Sold 60 sets
Error = 60 - 75 = -15Absolute error = |-15| = 15Percent error = 15/75*100% = 20%We can see absolute errors are same but percent errors are different.
The reason is the referenced numbers are different.

If 2x+3y=6 and -5x+2y=4 then what is x and y??
Answer:
x=0 y=2
Step-by-step explanation:
2x+3y=6 .... 1
-5x+2y=4 .... 2
Multiply 5 with equation 1 and multiply 2 with equation 2
Then we get
10x+15y=30
-10x+4y=8
-10x and +10x get canceled so 19y=38
y=38/19=2
substitute y value in equation 1 or 2 and find the value to get x

Write one example of a linear function and one example of a non-linear function in the format: y=mx +b
Answer:
Linear: 3x +9 =2x
Non Linear: x+2y=1 and x = y
Answer:
Examples, solutions, videos, and lessons to help Grade 8 students learn how to interpret the equation y = mx + b as defining a linear function, whose graph is a straight line; give examples of functions that are not linear.
For example, the function A = s2 giving the area of a square as a function of its side length is not linear because its graph contains the points (1,1), (2,4) and (3,9), which are not on a straight line.

A farmer builds a water trough to fit a corner. The water trough is made of two rectangular prisms.
PART A: Use the diagram to find the length A and the width B.
PART B: What is the volume of the water trough? Show your work.
(please explain this too and show your work if you can I really need help with this I don't understand)
PLEASE ACTUALLY HELP AND BE SERIOUS I DONT CARE IF YOU DONT KNOW THE ANSWER.
Volume is a three-dimensional scalar quantity. The volume of water through is 88 ft³.
What is volume?A volume is a scalar number that expresses the amount of three-dimensional space enclosed by a closed surface.
1. The measurement of A and B can be written as,
The value of A = 8ft - 3ft = 5ft
The value of B = 8ft - 4ft = 4ft
2. The volume of the water through = (8×3×2)+(5×4×2) = 48ft³+40ft³ = 88ft³
Hence, the volume of water through is 88 ft³.

Answer:
The answer is C. But I got 350.82
Step-by-step explanation:
The area for one triangle is 24 because A=h(height)b(base)timesb(base)/2. Both the triangles together would make 48 because 24+24=48
The are for one rectangle is 100.94 because A=b(base) times h(height). because there are 3 rectangles we multiply 100.94 times 3 which is 302.82
Then we add up all the areas 302.82+48 to get 350.82
Because this answer is slightly different I would assume it is C.
