The Answer Would Be D) 340% .
AleksAgata [21]3 years ago
3 0
It would be 340%. First, you need to find out what the fraction is for 2/5. 2/5 as a decimal would be .4. Next you put that back with the three which is 3.4. After that, you need to turn that into a percentage by multiplying it by 100 which then equals 340. add the % to it and that gives you 340%.

A sheet of bad paper is cut into 12 equal parts. What percent of the whole is 3 parts?
11Alexandr11 [23.1K]
25%

Divide 12 by 3 and you'll get 4.
That means 1/4 or a quarter of the 12 is 3.
(Convert the fraction to its percentage form)
1/4 or 1 divided by 4 equals 0.25
Multiply 0.25 by 100 and you'll get 25%

Does anyone know this?
weeeeeb [17]

Answer:

BC = 10.24

Step-by-step explanation:

You can use the Pythagoras theorem for this question

a^{2} + b^{2} = c^{2}

a = 8cm

b = ???

c = 13cm

We will solve for B (length BC)

a^{2} + b^{2} = c^{2}

8^{2} + b^{2} = 13^{2}

Rearrange for b

b^{2} = 13^{2} - 8^{2}

b^{2} = 105

b = \sqrt{105}

b = 10.24

Solve the two-step equation.<br><br> 14 = 31.7 – 3x<br><br> What is the solution?
shtirl [24]

Answer:

The answer is 5.9

Step-by-step explanation:

1) Subtract 31.7 from both sides.

14 - 31.7 =  - 3x

2) Simplify 14 - 31.7 to -17.7

- 17.7 =  - 3x

3) Divide both sides by -3.

\frac{ - 17.7}{ - 3}  = x

4) Simplify -17.7/-3 to 5.9

5.9 = x

5) Switch sides.

x = 5.9

Therefor, the answer is x = 5.9.
