What is the sum of 2/11’ 2/7’ and 1/11’?
pav-90 [236]
Solution

To solve this addition of fractions we are gonna apply the fraction rule which is;

a/c + b/c = (a + b)/c

2/11 + 1/11 = (2 + 1)/11


= (2 + 1)/11 + 2/7

Now add the numerators 2 + 1

= (2 + 1)/11 + 2/7

= 3/11 + 2/7

Now we find the least common multiple

The least common multiple of 11 and 7 is 77.

But before that we cross multiply the numerators.

3 * 7 = 21
2 * 11 = 22

Now the ajustes fraction is;

21/77 + 22/77


Apply the fraction rule which is;

a/c + b/c = (a + b)/c

= (21 + 22)/77

Now we add the numerators.

43/77

Therefore the answer in fraction is 43/77 and in decimal form it is 0.55841

Find the length of MP. round to the nearest hundredth.
lozanna [386]

Answer:

<h2>MP ≈ 2.98 cm</h2>

Step-by-step explanation:

Use sine:

sine=\dfrac{opposite}{hypotenuse}

We have:

opposite=MP\\hypotenuse=8.7\ cm\\\alpha=20^o\\\\\sin20^o\approx0.342

Substitute:

\dfrac{MP}{8.7}=0.342

\dfrac{MP}{8.7}=\dfrac{342}{1,000}              <em>cross multiply</em>

1,000MP=2975.4             <em>divide both sides by 1,000</em>

MP=2.9754\to MP\approx2.98
