Oi, tudo bem?

A resposta seria: Desse grupo, 20 mulheres não seriam estrangeiras.

Step-by-step explanation:

Esse grupo é formado por 400 pessoas, ao qual:

Homens:

30% = 30/100 = 0,3

400 . 0,3 = 120

Mulheres (Estrangeiras):

65% = 65/100 = 0,65

400 . 0,65 = 260

Neste caso, temos duas formas de resolver: ou descobrir a porcentagem da quantidade de mulheres que não são estrangeiras (isto é, '100% - (35% + 60% = 5%'), depois fazer a mesma fórmula como acima, que seria:

5% = 5/100 = 0,05

400 . 0,05 =  20

Ou também, podemos somar a quantidade de pessoas que nós já sabemos (que seria: '120 + 260 = 380') e subtrair a quantidade total de pessoas com esse resultado, que é:

400 - 380 = 20

Answer:

The answer is 6. commutative property of multiplication states that no matter the order, as long as all numbers are there, it equals the same amount.

Step-by-step explanation:

Answer:

6

Step-by-step explanation:

It's more like the missing property. This question is an example of the commutative property for multiplication. It does not matter what order you do the multiplying. 4*6 is the same as 6 * 4

Rational ...................

Step-by-step explanation:

A rational number is a number that can be express as the ratio of two integers. A number that cannot be expressed that way is irrational. For example, one third in decimal form is 0.33333333333333 (the threes go on forever). However, one third can be express as 1 divided by 3, and since 1 and 3 are both integers, one third is a rational number

Answer:

6 cups of blue paint

Step-by-step explanation:

The ratio can be written like this:

2:3 = x:9

9/3 = 3

3*2 = 6

x=6, so the answer is 6 cups of blue paint.

Answer:

Answer is Triangle P'R'Q' is larger, explain how you know is steps

Step-by-step explanation:

So a Dilation is the expansion or shrinkage of an object. Because this is being dilated by 1.5 it is growing by 1.5

So triangle PRQ is the smaller version of P'R'Q' because

Line PR  = 3.1

Line RQ = 3.9

Line QP = 5

Multiplying these by 1.5 you get

Line P'R' = 4.65

Line R'Q'= 5.85

Line Q'P' = 7.5

Answer:

x = 1

Step-by-step explanation:

f(x) = 3 or y = 3

Locate y = 3 on the y- axis , go horizontally across to meet the line at (1, 3 )

Then

When f(x) = 3 , x = 1

Answer:

Using the information in the exercise to develop the system of equations and using the substitution method, the following answers are found:

The system of the linear equations is P = F + 0.50, 2D = 3F - 0.50, and 2P + F + 3D = 7.75, where P = The price of a box of popcorn, D = The price of a drink, and F = The price of a piece of fruit. By other hand, the price of each item is: Popcorn = $1.50, Drink = $1.25, and Fruit = $1.

Solution of the system of equations by the Substitution Method.

Taking into account the information given in the exercise, we can write the next equations:

Where:

Since all equations have the variable F, we are going to use it as a key variable to represent the other variables in terms of F.

In the first equation we should not do anything, since P is in terms of F, in the second case the variable D is also in terms of F, but we need to find the value of just D, by this:

We proceed to substitute the first and second equations in the third equation:

And we solve for the variable F:

Now, we can solve for the variable D with the second equation:

Finally, we can solve for the variable P with the first equation:

So, we have the price of each item:

Answer:

i think its   26y/2

Answer:

Radius r = 1.

Step-by-step explanation:

Area of MNOP = (√2π)^2 = 2π.

Area 1 = Area 2, so

2π = 2πr^2

Dividing both sides by 2π:-

r^2 = 1.

r = 1.

yoo dang what math class is this

Step-by-step explanation:

Answer:

Closed numbers

Monomial

Step-by-step explanation:

Closed numbers are the only that makes sense

Anything times 0 is 0 thus it is only 3y which makes it a monomial

Step-by-step explanation:

7x - 5 = 8

7x = 8 + 5

7x = 13 (divide both sides by 7 to get x)

7x/7 = 13/7

x = 1.85714285714

Answer:

f(2) = g(2)

Step-by-step explanation:

If [tex]f(x)=2x[/tex] and [tex]g(x) = 2^x[/tex]

[tex]f(2) = 2*2 = 4\\g(2) = 2^2 = 4[/tex]

therefore, [tex]f(2) = g(2)[/tex]

Considering the angle theorems, the appropriate answer to the question is option D. m∠BEC + m∠CED = m∠BED; Angle Addition Postulate

In the diagram, lines BC and ED are parallel and both were intersected by a transversal AE. Thus it can be observed that:

m<ABC = BED = [tex]70^{o}[/tex] (corresponding angle theorem)

But,

m<BEC + m<CED = m<BED (angle addition postulate)

with m<CED = [tex]30^{o}[/tex], and m<BED = [tex]70^{o}[/tex]

So that,

m<BEC + [tex]30^{o}[/tex] = [tex]70^{o}[/tex]

m<BEC = [tex]70^{o}[/tex] - [tex]30^{o}[/tex]

         = [tex]40^{o}[/tex]

m<BEC = [tex]40^{o}[/tex]

Since linear pair are two angles that add up to [tex]180^{o}[/tex]. Therefore the required answer is option D.

i.e D. m∠BEC + m∠CED = m∠BED; Angle Addition Postulate

Answer:

125

Step-by-step explanation:

If you mean a 20 inch cube box then the answer is 125. Since 4 inch cubes have dimensions 4x4x4 and 20 inch cubes have dimensions 20x20x20. Then we can find the answer by dividing 20x20x20 by 4x4x4 which is equal to 5x5x5 as 20/4 = 5. Therefore the answer is 5x5x5 which is 125.

Answer:

The midpoint is (3, -2)

Step-by-step explanation:

[tex]m = (\frac{x1 + x2}{2}, \frac{y1 + y2}{2})\\m = (\frac{-7 + 13}{2}, \frac{2-6}{2})\\m = (\frac{6}{2}, \frac{-4}{2})\\m = (3, -2)[/tex]
