You estimate that the length of your
classroom is 20 feet. The actual length is 25
feet. Find the percent of error.

Answers

Answer 1

Answer:

The percent error is 20%.

Step-by-step explanation:

The general formula is to subtract the actual value from the estimated value, take the absolute value of the difference, divide that answer by the actual value, then multiply it by 100.

So, 20 (estimated) minus 25 (actual) is -5. The absolute value of -5 would be 5, since absolute value is always positive. Divide 5 by the actual value, 25, and you get 0.2. Multiply 0.2 by 100 to get a percent value, and the answer will amount to 20%. Hope this helps.

Which equation is NOT a linear function?

Answers

Answer:

y=x^2-2

Step-by-step explanation:

Linear functions have a constant slope, so nonlinear functions have a slope that varies between points. Algebraically, linear functions are polynomials with highest exponent equal to 1 or of the form y = c where c is constant. Nonlinear functions are all other functions. An example of a nonlinear function is y = x^2

Answer:

y=x^2 -2

Step-by-step explanation:

This will result in a parabola, which does not fit the description of a linear function.

In a complete sentence, explain the similarities and differences
between finding circumference when the radius is given and finding
the circumference when the diameter is given.

Answers

Answer:

Mathematically speaking, both of these are what are called measures. They are ways of getting at the size of something.

The circumference of a circle is a line, which is one-dimensional, which means it has length but zero width. The area of a circle, in contrast, is two-dimensional. This is the essential difference.

The consequence of this is that circumference is measured in units like centrimetres, or inches, or miles. But area is measured in units like square-centimetres, square inches, or square miles.

Is this what you meant?

Answer:

the circumference is the distance around the circle so u can use the formula c=2πr

the radius formula is r=c/2π

the diameter formula is d=2r

If x=3 and y = ─ 4 , find i) (x─y) ─ y ii) ( x+y) +x 2. Write two pairs of numbers satisfying the equation xꓥ2 + yꓥ2 = 25

Answers

Answer:

i)  (x -y) -y  = 11

ii) (x+y) + x² = 8

iii) The two pairs (( 3 , -4)) and ( ( 3 ,4) satisfy the equation   x² + y² = 25

Step-by-step explanation:

Step(i):-

Given that x =3 and y=-4

i)  (x -y) -y = (3-(-4))-(-4) = 3+4+4 = 11

ii) (x+y) + x² = ( 3 -4) + (3)² = -1 + 9 = 8

Step(ii):-

Given equation  

                    x² + y² = 25

we can choose (x,y) = ( 3 , -4)

                 3²+(-4)² = 25

                     25    = 25

The ordered pair ( 3,-4) satisfies the equation

second ordered pair ( 3 ,4)

                        x² + y² = 25

                       9 + 16 = 25

                           25 = 25

Final answer:-

i)  (x -y) -y  = 11

ii) (x+y) + x² = 8

iii) The two pairs (( 3 , -4)) and ( ( 3 ,4) satisfy the equation   x² + y² = 25

Owen has a square sheet of paper that measures 1 foot on each side. He folds the paper vertically and horizontally so that it makes equal sections. The model below shows the unfolded paper.

Answers

Answer:

The areas of the equal sections of boxes formed is 0.25ft^2

Step-by-step explanation:

The question is not complete, as we are not told what to solve for, nevertheless, we can make some findings from the given information

Given data

We are told that the dimension of the paper is 1 ft

So, when the paper is folded twice, one horizontal and one vertical, the dimension of each box will be 0.5 ft

Hence there will be 4 boxes formed

And their areas will be

Area= 0.5*0.5

Area= 0.25ft^2
