Answer:
= 22/3 + 28/5
= ((22 × 5) + (28 × 3)) / (3 × 5)
= (110 + 84) / 15
= 194/15
= 194/15
= 12 14/15
.Adding Mixed Numbers:
Convert the mixed numbers into fractions.
Use the algebraic formula for addition of fractions: a/b + c/d = (ad + bc) / bd.
Answer:
Angle B is 54º.
Step-by-step explanation:
First, find <em>x</em>. Since angle A and angle B are supplementary angles, they add up to 180º.
(7<em>x</em> + 7)º + (4<em>x</em> - 14)º = 180º.
11<em>x</em> - 7 = 180
11x = 187
<em>x</em> = 17.
Now, substitute 17 for <em>x</em> in angle B's equation, (4<em>x</em> - 14).
4(17) - 14
= 68 - 14
= 54º

Substitute 350 for s in
Take:
So, we have:
--- approximated
Answer: 2√10 - √30
explanation:
ok so they’re asking for the difference between the lengths of the sides of each cube. they have different SA’s (surface areas). all you gotta do is plug in the SA in the given equation to find the length of the side and THEN you subtract the answers and thats how you find the difference between the sides.
given:
s = √(SA/6)
SA1 = 240 m^2
SA2 = 180 m^2
S1 = √(240/6) = 2√10 or 6.32
S2 = √(180/6) = √30 or 5.47
s1 -s2 = 2√10 - √30
You do 12x4 which is 48. 48 is the answer
