Answer:
i beleve they would get an 80% sorry if im wrong
Answer:
the answer is 80%
Step-by-step explanation:
Think of it this way
There is 5 problems wrong out of 25 so 5/25 is the fraction (right/ number of questions)
5/25 can be simplified to 1/5 (divide by 5)
1/5 can be transformed to the percentage 20%
NOW BE CAREFUL 20% is what is WRONG so 100-20=80
so 80% is thus the answer

Answer: C

Answer: D
Step-by-step explanation:
1.88 in the equation is the rate of change.
rate of change means, "the speed at which a variable changes over a specific period of time."
L = the length of his femur. every time the femur grows an inch, the height also increases according to the equation.
an example is when the femur is 19 inches.
H = 1.88(19) + 32.01
H = 67.73
The height of the man is 67.72 inches if his femur was 19 inches.
Solve for X
If you have 2x+3
Answer:
in the explanation
Step-by-step explanation:
According to the triangle midsegment theorem (if these points are midpoints),
2x + 3 is two times longer than 7, meaning it's 14.
2x+3=14
2x=11
x = 11/2
If there is an option for not enough info given, that should be right as it doesn't actually say that they are midpoints

The sum of 2 numbers is 38. The grarter number is 8 more than the other number find each number ise a aystem of linear equations to justify your answer
Answer:
x = 23 ; y = 15
Step-by-step explanation:
Given :
Let the numbers be : x and y
x + y = 38 - - (1)
x = y + 8 - - - (1)
Put x = y + 8 into (1)
y + 8 + y = 38
2y + 8 = 38
2y = 38 - 8
2y = 30
y = 30/2
y = 15
x = y + 8
x = 15 + 8
x = 23
The length of a rectangular park is twice its width.
The park is surrounded by a 3-foot-wide path.
Write a quadratic function to represent the total
area of the park and the path.
Answer:
[tex]A=2x^2+18x+36[/tex]
Step-by-step explanation:
Quadratic Function
It's given the length of a rectangular park is twice its width.
Let's call:
x = width of the rectangular park
2x = length of the rectangular park
The park is surrounded by a 3-foot-wide path. This path adds 3 ft twice to both dimensions, i.e.:
x+3+3=x+6 width of the park and the path
2x+3+3=2x+6 length of the park and the path
The total area is:
A=(x+6)(2x+6)
Operating:
[tex]A=2x^2+6x+12x+36[/tex]
[tex]\boxed{A=2x^2+18x+36}[/tex]

The polynomial p(x) = 5x^3 – 9x^2 - 6x + 8 has a known factor of (x + 1).
Rewrite p(x) as a product of linear factors.
Answer:
[tex](x+1)(5x-4)(x-2)[/tex]
Step-by-step explanation:
We know that (x+1) is a factor, so we can use synthetic division to factor it out of [tex]5x^3-9x^2-6x+8[/tex].
Once factored, we get [tex](x+1)(5x^2-14x+8)[/tex]
Now all we need to do is factor[tex](5x^2-14x+8)[/tex]
[tex](5x^2-14x+8)=(5x-4)(x-2)[/tex]
This gives us the answer [tex](x+1)(5x-4)(x-2)[/tex].
p(x) as a product of its linear factors is:
[tex]p(x) = (x+1)(x-2)(5x-4)[/tex]
The given polynomial is:
[tex]p(x) = 5x^3-9x^2-6x+8[/tex]
The divisor = x + 1
The division expression can be written as:
[tex]\frac{5x^3 - 9x^2 -6x + 8 }{x+1} \\\\= 5x^2-14x+8[/tex]
Factorize [tex]5x^2-14x+8[/tex]
[tex]5x^2-14x+8\\\\5x^2-10x-4x+8\\\\5x(x-2)-4(x-2)\\\\(5x-4)(x-2)[/tex]
Therefore, p(x) as a product of its linear factors is written as:
[tex]p(x) = (x+1)(x-2)(5x-4)[/tex]

The dimensions of an iron box are 9ft * 4.4ft* 2.5ft. What is the cost of the iron sheet used to make the box, if the cost of the sheet is Rs 6 per Square Foot?
Answer:
Rs 877.2
Step-by-step explanation:
The dimensions of an iron box are 9ft * 4.4ft* 2.5ft. What is the cost of the iron sheet used to make the box, if the cost of the sheet is Rs 6 per Square Foot?
The iron box is shaped as a rectangular prism
The formula for the surface area of a rectangular prism is given as:
S = 2(lw + lh + wh)
L = Length = 9ft
W = Width = 4.4ft
H = Height = 2.5 ft
Hence:
Surface area = 2[(9 × 4.4) + (9 × 2.5) +(4.4 × 2.5)]
Surface area = 2[(39.6) + (22.5) + (11)]
Surface area = 2[73.1]
Surface area = 146.2 ft²
From the question:
The cost of the sheet is Rs 6 per Square Foot
1 ft² = Rs 6
146.2 ft² = x
Cross Multiply
x = 146.2 × Rs 6
x = Rs 877.2
The cost of the iron sheet used to make the box is Rs 877.2

Is the ratio 4.2:1.5 proportional to the ratio 12:5? Explain.
Answer:
No.
Step-by-step explanation:
We can set this proportion up as:
[tex]\frac{4.2}{1.5}=\frac{12}{5}[/tex]
For this to be true, cross-products need to be equal:
[tex]4.2(5)=12(1.5)[/tex],
However, we can see that this is not the case:
[tex]4.2\cdot 5 \neq 12 \cdot 1.5[/tex]
Therefore, these ratios are not proportional.
