If you got 55.6% on a test and that test is worth 80%

So first let us calculate the actual percentage that you scored.

The actual percentage is

\begin{gathered} \frac{0.556}{0.80}=0.695 \\ 0.695\times100=69.5\% \end{gathered}

So your actual score on the test is 69.5%

The grading system varies across countries and states

The traditional grading scale is given below

90% to 100% corresponds to A grade.

80% to 89% corresponds to B grade.

70% to 79% corresponds to C grade.

60% to 69% corresponds to D grade.

0% to 59% corresponds to F grade.

69.5% can be rounded off to 70%

Therefore, 69.5% corresponds to C grade.

(note: the above grade is not valid in case your school follows a different grading scale)

The area of a rectangle is 14 yd2 , and the length of the rectangle is 3 yd less than twice the width. find the dimensions of th
ExtremeBDS [4]
Let x be the width 
2x-3= length 

(2x-3)(x)=14
2x^2-3x=14 
2x^2-3x-14=0 
(2x- 7)(x+2)=0 
x=7/2 or x=-2

Since we know that negative values cannot exist in distance, we have to take 7/2 to as the correct answer. 

The width would be 3.5 yards 
Length= 2(3.5)-3 
=4 yards 

3.5 x 4 yards is the dimension of the rectangle 

Hope I helped :)

2..52 X 10 to the fifth????<br><br>PLS HELPP!
love history [14]

Answer:

252000

Step-by-step explanation:

we take 2.52 and move the decimal back 5 places. when we run out of numbers we add zeros. so if we moved 3 places back it would be 2520 but since we move 5 it is 252000. 10 by any power you just move the decimal place if it is negtive move it forward if positive move backward.

Answer:

  f^-1(x) = 4+∛((x-6)/5)

Step-by-step explanation:

To find the inverse function, solve ...

  x = f(y)

then write the answer in functional form.

  \displaystyle x=f(y)\\\\x=5(y-4)^3+6\\\\x-6=5(y-4)^3\\\\\frac{x-6}{5}=(y-4)^3\\\\\sqrt[3]{\frac{x-6}{5}}=y-4\\\\y=4+\sqrt[3]{\frac{x-6}{5}}\\\\\boxed{f^{-1}(x)=4+\sqrt[3]{\frac{x-6}{5}}}

__

The graph shows the function and its inverse to be reflections of each other in the line y=x, as they should be.

marshall27 [118]
Hello there,

best way to do this one is set up your story line....

4h + 8h + 50 = 164$...

let's make this easier to look at and combine like terms..

12h + 50 = 164$...

Beautiful!!! Now let's try and get the h alone?...

minus 50 to both sides...

12h = 114$..

now divide both sides by 12...

H= 9.50$/hour

Looks like you made 9.50$ an hour but Hey, at least you got that bonus ;)
