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.

Answers

Answer:200

Step-by-step explanation:

Answer:

No, different

Step-by-step explanation:

Last year

Bought 40 sets

Sold 25 sets

Error = 25 - 40 = -15Absolute error = | - 15| = 15Percent error =  15/40*100% = 37.5%This year

Bought 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.

can someone help me with this thank you

2y^2 + 30xy - 2y^2 + 4y - 4x

Answers

you're gonna have 2y^2 - 2y^2 which cancel out giving you 0 so they dont go into the simplified answer. then, since 30xy is the only one that doesnt have a match you place that down. then place +4y , and then -4x . It will give you 30xy +4y -4x .

or vise versa with the 4y and 4x . whichever your answer choices are or how u prefer to write it. <3

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 .

Answers

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.

If 2x+3y=6 and -5x+2y=4 then what is x and y??

Answers

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

Answers

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.

PLEASE ACTUALLY HELP AND BE SERIOUS I DONT CARE IF YOU DONT KNOW THE ANSWER.

Answers

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.
