If 5/x = 15/x+20, what is the value of x/5?

Mumz [18]

Answer:

c) 2

Step-by-step explanation:

here you can use cross multiplication. that's where you turn the fraction into an equation. ( there's videos about it, I'm not very good at explaining )

so you can turn

$\frac{5}{x} = \frac{15}{x + 20}$

into

5(x + 20) = 15x

5x + 100 = 15x

subtract 5x from both sides

100 = 10x

x = 10.

the value of x/5 would be 2, since 10/5 is 2.

Is 20, 101, and 99 a Pythagorean triple

Alexxx [7]

Answer:

yes

Step-by-step explanation:

Using the Pythagorean Theorem, we should get 20² + 99² = 101² and we need to check if this is a true statement.

400 + 9801 = 10201

10201 = 10201 so yes, it is.

A ship travels due west for 90 miles and turns to travel 80 miles in the northwest direction at a 120 degree angle. How far is t

adoni [48]

We breakdown the components of the distances.
(1) 90 miles west.
x - component = -90 miles
y - component = 0 miles
(2) 80 miles, northwest (120°)
x - component = (80 miles)*(sin 30°) = 40 miles (negative)
y - component =(80 miles)*(cos 30°) = 69.282 miles (positive)

Solve for the distance,
√(-90 - - 40)² + (69.282 miles)² = <em>147.31 miles</em>

If I get a 55.6% on a test an the test is worth 80% what is my grade on that test A,B,C,D,F

Fittoniya [83]

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)
