Pls Someone help me I don't understand math very well can someone help me on how to get the answer for 1/4 x 8 4/9?
Answers
Answer:
2 4/36
Step-by-step explanation:
To do this, multiply the whole number by the denominator and add it to the numerator.
8 x 9 = 72
72 + 4 = 76
76/9
Then multiply across (multiply numerators with numerators; denominators with denominators)
76 x 1 = 76
9 x 4 = 36
76/36 = 2 4/36
____________________________
A faster way to do this is to multiply the whole number by the fraction and then the fraction by the fraction.
1/4 x 8/1 = 8/4 = 2
1/4 x 4/9 = 4/36
= 2 4/36
Answer:
2 1/9
Step-by-step explanation:
Multiplying fractions: Numerator times numerator over denominator times denominator. IF you have a mixed number, convert it into improper fraction, then do numerator times numerator over denominator times denominator.
1/4 x 76/9 (I got 76/9 because the 8 means 8 9/9s, so (8 x 9)=72 plus 4 because 4/9s=76/9)
1/4 x 76/9= 76/36
=38/18
=19/9
=2 1/9

Find The value of H:
S=2πr(r+h)
Answers
Answer:
[S / (2πr)] - r = h
Step-by-step explanation:
You can't solve for H because there isn't a capital H in the equation. However, I'm going to pretend its "h" because that might have been a mistake.
S = 2πr(r + h)
Divide by 2πr to try to isolate h
S / (2πr) = r + h
Subtract r from both sides to get h by itself
[S / (2πr)] - r = h
That is your final answer.
[tex]\\ \rm\Rrightarrow S=2\pir(r+h)[/tex]
[tex]\\ \rm\Rrightarrow r+h=\dfrac{S}{2\pi r}[/tex]
[tex]\\ \rm\Rrightarrow h=\dfrac{S}{2\pi r}-r[/tex]
[tex]\\ \rm\Rightarrow h=\dfrac{S-2\pi r^2}{2\pi r}[/tex]
