Answer:

whatever% of anything, is just (whatever/100) * anything.

there were a total of 560000 votes, now, off those some are valid and some are invalid.

we know 15% of that are invalid, that simply means that 85% are valid, since 85% + 15% is the whole thing, or 100%, if 15% are not good, the other 85% are the good ones.

how many are the valid ones anyway? well, 85% of 560000, which is just (85/100) * 560000.

we know that off those valid ones, the candidate got 75% of those, so how much is 75% of that?

well, (75/100) * [ (85/100) * 560000 ].

Answer:

See below ↓

Step-by-step explanation:

Score of the student on examination = marks scored / total marks
Score = 235/300 [Divide throughout by 5]
Score = 47/60 [Using long division, approximate to tenths place]
Score = 0.783 [Multiply with 100 to convert decimals → percentage]
Score = 78.3%

Total valid votes = 560 x (100 - 15)%
Total valid votes = 560 x 0.85
Total valid votes = 476
Votes for Magie N. Hawa = 476 x 70%
Votes for Magie N. Hawa = 333.2 ≅ 333 votes

108 girls = (100 - 70)% of pupils
108 / 0.3 = number of pupils
360 pupils

if the sum of the first 60 positive integers is s, what is the sum of the first 120 integers in terms of s? a. 2s 3600 b. s^2 36

kvasek [131]

For the first 60 positive integers, a = 1, n = 60, l = 60.
Sn = n/2(a + l)
s = 60/2(1 + 60) = 30(61)

For the next 60 positive integer, a = 61, n = 60, l = 120
Sum = 60/2(61 + 120) = 30(61 + 120) = 30(61) + 30(120) = s + 3600

Sum of first 120 positive integers = s + s + 3600 = 2s + 3600

I need help on this question plz

Given is triangle with base = 10 cm and perpendicular height = 3 cm.

We know the formula for area of triangle is given by :-

Area = $\frac{1}{2}$ × (Base) × (perpendicular height)

Area = $\frac{1}{2}$ × (10) × (3)

Area = $\frac{30}{2}$

Area = 15 cm²

So, final answer is 15 cm².

Answer:

First, we can write:

Next, we can multiply each side by

100

giving:

The number of boys varies directly as the number of girls and inversely as the number of teachers. When there are 24 boys and 16

lidiya [134]

SO from what I did was...

Since 24 x 3 = 72 , I did the same to 16.

16 x 3 = 48

But because instead of their being 3 teachers there is 1... What I did is just was to divide 48 / 2 which gave me the answer of 24...

So what I think the answer is...

There are 72 boys, 24 girls, and 1 teacher...

Unless I am just dumb and it would be 48 girls, but I think I did it right.

I hope I was able to help out.

156-36+36=84/2= 42 <—— the missing length.

Area would be 36x42= 1,512.
