First, convert the percentage to a decimal. You can do this by moving the decimal place two places to the left.
Now, simply multiply that decimal by using a calculator.
Answer:
2
Step-by-step explanation:
let the number be n, then
n = 4n - 6 ( subtract 4n from both sides )
- 3n = - 6 ( divide both sides by - 3 )
n = 2
That is the number is 2
Answer:
Step-by-step explanation:
1609.34
The answer is
work:
208/2 = 114
now this is easier.
the answer is 62, as 62 is 10 more than 52, so once added,(obviously) that gets you 114, and the width is 52.
Given we don't know which is the hypotenuse, either FE is, or DF is. Note it can't be DE as the hypotenuse is the longest side and you already know FE is longer than DE.
<span>According to pythagoras: </span>
<span>either FE² = DE² + DF² </span>
<span>or DF² = DE² + FE² </span>
<span>8² = 6² + x² </span>
<span>x² = 64 - 36 </span>
<span>x = √28 = 5.291... </span>
<span>Not one of the given answers so... </span>
<span>x² = 6² + 8² </span>
<span>x² = 36 + 64 </span>
<span>x = √100 = 10 </span>
<span>answer: B) 10 for the frist one</span>
