The ratio of in-state to out-of-state visitors at the zoo is approximately 7 to 3. If 2000 people visited the zoo, about how many people were from out-of-state?

Answer:

x = 3z(y - 2)

Step-by-step explanation:

Given

[tex]\frac{x}{3z}[/tex] = y - 2 ( multiply both sides by 3z to clear the fraction )

x = 3z(y - 2)

Actually Welcome to the Concept of the Simple maths.

Here,

61 = r/3 - 7

hence, r/3 = 61+7

===> r/3 = 68

==> r = 68*3

====> r = 204

Answer:

33 degrees

Step-by-step explanation:

Complementary angles are 90 degrees when added.

So to find the measure of the other angle just subtract 57 from 90.

90 - 57 = 33

Answer:

21x² + 22x - 8

Step-by-step explanation:

(3x+4)(7x-2)​ = 21x² - 6x + 28x - 8 = 21x² + 22x - 8

Answer:

B.

Step-by-step explanation:

Let's use the FOIL (First, Outside, Inner, Last) method.

We need to multiply the first terms in each pair of parentheses, which are

3x and 7x.

Multiplying, we get [tex]21x^2[/tex].

We multiply the outside terms in each pair, which are 3x and -2.

Multiplying, we get [tex]-6x[/tex]. Remember that since -2 is negative, then the whole product is negative.

We need to multiply the inner terms now. They are 4 and 7x.

Multiplying, we get [tex]28x[/tex].

Finally, we multiply the last terms in each pair of parentheses. they are 4 and -2.

Multiplying, we get [tex]-8[/tex].

Now, we put the terms together.

[tex]21x^2-6x+28x-8[/tex]

We can combine -6x, and 28x. Doing this, we get

[tex]21x^2+22x-8[/tex]. Which gives us B.

Answer:

The Answer Is 10

Step-by-step explanation:

The Total Strength = 40 Students

The Ratio Of Boys To Girls = 3:5

So, 3 + 5 = 8

Then, Divide 8/40 So That U Get The Number Then Multiply It With The Ratio.

•8/40 = 5

•5 × 3 = Boys Strength Which Is = 15

•5 × 5 = Girls Strength Which Is = 25

So, There Are 10 Girls More Than Boys.

Hope It Helps U.

Answer:

A = 16π cm²

Step-by-step explanation:

We require to find the radius r

Given circumference C = 8π , then

2πr = 8π ( divide both sides by 2π )

r = 4 , then

A = πr² = π × 4² = 16π cm²

Answer:

A = 16π cm²

The correct statement about the math class is the the girls make up 8/15 of the class.

Ratio expresses the relationship between two or more numbers. It shows the frequency of the number of times that one value is contained within other value(s).

Ratio of the number of girls in the class = number of girls in the class / sum of ratios

8 / (7 + 8 )  = 8 / 15

Answer:

1) 11x^3 - 6x - 3

2) 3x^3 + 4x^2 - 2x - 1

3) 9x^2 - 4

4) -4x^4 + 2x^3 - x^2

5) x^3 - 38x - 12

Step-by-step explanation:

1) (3x^4 + 5x^3 - 7x + 2) - (3x^4 - 6x^3 - x + 5)

Step 1: 3x^4 + 5x^3 - 7x + 2 - 3x^4 + 6x^3 + x - 5 (multiply the terms in the parenthesis by the constants, which are 1 and -1)

Step 2: 3x^4 - 3x^4 + 5x^3 + 6x^3 - 7x + x + 2 - 5 (reorganize the polynomial by exponential values (ex: x^4 before x^3 before x^1))

Step 3: 11x^3 - 6x - 3 (add like terms)

2) (3x^3 + 8x - 3) + (4x^2 - 10x + 2)

Step 1: 3x^3 + 8x - 3 + 4x^2 - 10x + 2 (multiply the terms in the parenthesis by the constants)

Step 2: 3x^3 + 4x^2 + 8x - 10x - 3 + 2 (reorganize the polynomial)

Step 3: 3x^3 + 4x^2 - 2x - 1 (add like terms)

3) (3x + 2)(3x - 2)

Step 1: 9x^2 - 6x + 6x - 4 (Use FOIL to multiply binomials, or multiply the first terms, outside terms, inside terms, then last terms)

Step 2: 9x^2 - 4 (add like terms)

4) -x^2(4x^2 - 2x + 1)

Step 1: (-x^2*4x^2) + (-x^2*(-2x)) + (-x^2*1) (multiply -x^2 by each term)

Step 2: -4x^4 + 2x^3 - x^2 (simplify; remember x^2 is the same as -1*x^2)

5) (x + 6)(x^2 - 6x - 2)

Step 1: ((x*x^2) + (x*(-6x)) + (x*(-2))) + ((6*x^2) + (6*(-6x)) + (6*(-2))) (multiply the first term in the binomial by each term in the trinomial, and do the same with the second term)

Step 2: x^3 - 6x^2 + 6x^2 - 2x - 36x - 12 (simplify and reorganize)

Step 3: x^3 - 38x - 12 (add like terms again)
