There are men and woman and children at a party. 30% of the people at the party are children, 35% are men and the rest are woman

kotykmax [81]

Answer:

84 men

Step-by-step explanation:

The ratio of men to children is ...

men/children = 35%/30% = 7/6

Given the number of children is 72, the number of men is ...

men/children = 7/6 = men/72

men = (7/6)(72) = 84

There are 84 men at the party.

_____

Additional comment

The fraction of women is 100% -30% -35% = 35%, the same as the number of men. There are 84 women at the party and 240 total people.

Please someone help me with this! Giving brainliest :)

olga2289 [7]

Answer:

$n=3$

Step-by-step explanation:

Note that $2^5*5^2=2^3*2^2*5^2=2^3*(2*5)^2=2^3*10^2$ .

Aha! We see a path to the solution!

We now know that our equation is actually $2^3*10^2=2^{n}*10^2$ .

We can divide both sides by $10^2$ to get $2^3=2^{n}$ .

By inspection or taking the logarithm base 2 of both sides, we see that $3=n$ .

So, the answer is $\boxed{n=3}$ and we're done!

Let P(1,2,1), Q(1,0,-1), R(2,2,0) be the vertices of a parallelogram with adjacent sides PQ and PR. Find the other vertex S.

ladessa [460]

Given:

The vertices of a parallelogram are P(1,2,1), Q(1,0,-1), R(2,2,0).

PQ and PR are the adjacent sides of the parallelogram.

To find:

The coordinates of vertex S.

Solution:

We know that, the diagonals of a parallelogram bisect each other.

Let the coordinates of the vertex S are (a,b,c).

In the given parallelogram PS and QR are the diagonals. It means their midpoints are same.

$\left(\dfrac{1+a}{2},\dfrac{2+b}{2},\dfrac{1+c}{2}\right)=\left(\dfrac{1+2}{2},\dfrac{0+2}{2},\dfrac{-1+0}{2}\right)$

$\left(\dfrac{1+a}{2},\dfrac{2+b}{2},\dfrac{1+c}{2}\right)=\left(\dfrac{3}{2},\dfrac{2}{2},\dfrac{-1}{2}\right)$

On comparing both sides, we get

$\dfrac{1+a}{2}=\dfrac{3}{2}$

$1+a=3$

$a=3-1$

$a=2$

Similarly,

$\dfrac{2+b}{2}=\dfrac{2}{2}$

$2+b=2$

$b=2-2$

$b=0$

And,

$\dfrac{1+c}{2}=\dfrac{-1}{2}$

$1+c=-1$

$c=-1-1$

$c=-2$

Hence, the coordinates of vertex S are (2,0,-2).

Which is another way to check the sum of 104+34+228+877?

Alex787 [66]

The answer is digit sum method.

Digit sum method is method used to check the sum of sum numbers. If the sum of all of the digits of numbers is equal to the sum of all of the digits of the total sum, then the arithmetic process was correct.

We need to check the sum of 104+34+228+877:
104 + 34 + 228 + 877 = 1243

Let's first summarize the digits of individual numbers:
104 *** 1 + 0 + 4 = 5
34 *** 3 + 4 = 7
228 *** 2 + 2 + 8 = 12 *** 1 + 2 = 3
877 *** 8 + 7 + 7 = 22 *** 2 + 2 = 4

Now, let's sum these sums:
5 + 7 + 3 + 4 = 19 *** 1 + 9 = 10 *** 1 + 0 = 1

Then, let's summarize the digits of the total sum:
1243 *** 1 + 2 + 4 + 3 = 10 *** 1 + 0 = 1

Since the sums of the digits on the both sides of equation is 1, than the arithmetic process was correct and the sum of 104 + 34 + 228 + 877 is really 1243.
