Hey You!

12/40 = Candidate A.

18/40 = Candidate B.

12 + 18 = 30

40 - 30 = 10

10/40 = Those who didn't vote.

ANSWER:

12 ÷ 40 = .3 (30%) So 30% voted for Candidate A.

18 ÷ 40 = .45 (45%) So 45% voted for Candidate B.

10 ÷ 40 = .25 (25%) So 25% didn't vote at all.

I’m so confused I need help please!!
shutvik [7]

Answer:

5. 9 8. 2\sqrt{10}

Step-by-step explanation:

a²+b²=c²

so for #5 12²+b²=15²

144+b²=225 (subtract 144 from both sides)

b²=81

b=9

For #8

9²+b²=11²

81+b²=121 (subtract 81 from both sides)

b²=40

b=\sqrt{40}

\sqrt{40}=

2\sqrt{10}

A parallelogram has a perimeter of 42 meters. Two sides are each 19.8 meters long. What is the length of the other two sides?
ValentinkaMS [17]
We first add both 19.8 by 19.8 and therefore, that would give us 39.6.

42 - 39.6 = 2.4.

2.4 ÷ 2 = 1.2

1.2 would be the length of each sides.
