The paperboy delivers 63 papers per hour.

First, you must set up the equation.

[tex]\frac{189}{3}=\frac{x}{1}[/tex]

Then, you must cross multiply.

[tex]189=3x[/tex]

Then, divide 3 on both sides.

Answer: 66 feet per second.

Answer: 66 feet per second

Step-by-step explanation: Hope this helps :)

Given:

Consider the given formula is

[tex]t=\dfrac{\sqrt{h}}{4}[/tex]

It represents the time t in seconds that it takes an object to fall from a height of h feet.

An egg falls from a height of 330 feet

To find:

The time taken by egg to reach the ground.

Solution:

We have,

[tex]t=\dfrac{\sqrt{h}}{4}[/tex]

Substitute h=330 in the above formula.

[tex]t=\dfrac{\sqrt{330}}{4}[/tex]

[tex]t=\dfrac{18.1659}{4}[/tex]

[tex]t=4.541475[/tex]

[tex]t\approx 4.54[/tex]

Therefore, the egg reach to the ground in about 4.54 seconds.

Required answer:

[tex] \huge{ \boxed{\bold{ \tt{45 = 2x}}}}[/tex]

Question:

Use cross products to identify the equation needed to solve this proportion:

5/x = 2/9

0 5x = 18

0 2x = 45

O 9x = 10

O 2x = 14

Equation Given:

5/x = 2/9

Step by step explanation:

[tex]: \implies \frac{5}{x} = \frac{2}{9}

[/tex]

equation formed

[tex]: \implies \: 5 \times 9 = 2 \times x[/tex]

we have taken 9 up to multiply it with 5 and x up to multiply it with2

[tex]: \implies \: 45 = 2x[/tex]

after multiplication we get 45 = 2x

extra steps:

[tex]: \implies \: x=\frac{45}{2}[/tex]

transferring 2 to other side to divide it with 45

[tex]: \implies \: x=22.5[/tex]

so finally we get 22.5

Answer:

We need 5.7 liters of the 5% volume solution and 4.3 liters of the 40% volume solution.

Step-by-step explanation:

Let V₁ be the volume of the 5% solution required and V₂ be the volume of 40% solution required.

Since mass = concentration × volume, the combined mass of the 5% and 40% volume solution equal the mass of the 10 liter 20% volume solution.

So, 0.05V₁ + 0.4V₂ = 0.2 × 10

0.05V₁ + 0.4V₂ = 2 (1)

Also, the total volume of the solution must equal 10 liters. So,

V₁ + V₂ = 10 (2)

V₁ = 10 - V₂  (3)

substituting (3) into (1), we have

0.05(10 - V₂) + 0.4V₂ = 2

0.5 - 0.05V₂ + 0.4V₂ = 2

collecting like terms, we have

- 0.05V₂ + 0.4V₂ = 2 - 0.5

0.35V₂ = 1.5

dividing through by 0.35, we have

V₂ = 1.5/0.35

V₂ = 4.29

V₂ = 4.3 liters to the nearest tenth of a liter

Substituting V₂ into (3), we have,

V₁ = 10 - 4.3  

V₁ = 5.7 liters

So, we need 5.7 liters of the 5% volume solution and 4.3 liters of the 40% volume solution.

6 - 3x = 5x - 10x + 6

combine like terms

6 - 3x = -5x + 6

subtract 6 from both sides

-3x = -5x

x = 0

Step-by-step explanation:

6-6 = 5x - 10x +3x

0= - 2x

Divide both sides by -2

X = 0/-2x

What equation?

Equations are used to represent equal expressions.

The statement that describes all three equations is that: they all represent perfect squares

The equations are given as:

[tex]x^2 - 81 = 0[/tex]

[tex]b^2 - 49 = 0[/tex]

[tex]3c^2 - 75 = 0[/tex]

By observation, we can see that all three equations represent perfect squares.

The proof is as follows:

[tex]x^2 - 81 = 0[/tex]

[tex]x^2 = 81[/tex]

Take square roots

[tex]x = 9[/tex]

[tex]b^2 - 49 = 0[/tex]

[tex]b^2 = 49[/tex]

Take square roots

[tex]b = 7[/tex]

[tex]3c^2 - 75 = 0[/tex]

[tex]3c^2 = 75[/tex]

Divide by 3

[tex]c^2 = 25[/tex]

Take square roots

[tex]c = 5[/tex]

Hence, the statement that describes all three equations is that: they all represent perfect squares

Step-by-step explanation:

Answer:

[tex]n = 5[/tex]

Step-by-step explanation:

[tex]2n = 3n - 5[/tex]

solve for n

[tex]5 = 3n - 2n[/tex]

[tex]5 = n[/tex]

For the above mathematical statement, n equals 5.

An operation in mathematics is a function that transforms one or more parameters or operands into a clearly defined output value. In mathematics, addition, subtraction, multiplication, division, and modular forms are the five basic operations.

Given, Twice a number (n) is the same as five less than three times the number.

Thus

2 *n = 3n - 5

as given in the problem

3n -2n = 5

n = 5

therefore, the value of n is 5 for the given Mathematical expression.

Answer:

A. f(2) = g(2)

Step-by-step explanation:

We see from the graph that the line intersects when x = 2.

Therefore, when x = 2, f(2) will equal g(2).

f(0) = 2, and g(0) = -2, so they are not equal and B is wrong.

f(2) = 0 and g(0) = -2, so they are not equal and C is wrong.

f(0) = 2 and g(2) = 0, so they are not equal and D is wrong.

Answer:

first one is rational, second is also rational, third is rational, fourth is rational, and fifth is irrational.

Step-by-step explanation:

Rational numbers are numbers that can be expressed as a fraction or part of a whole number. (examples: -7, 2/3, 3.75) Irrational numbers are numbers that cannot be expressed as a fraction or ratio of two integers. The reason why [tex]\sqrt{12}[/tex] is an irrational number is bc it's not a perfect square while[tex]\sqrt{49}[/tex] equals to 7 and is a perfect square.

6 kids in total, 4 girls 2 boys

pink to blue .        girls to boys .  

the girls to boys ratio is 4:2

the answer cannot be A because 4:8 is not equivalent to 4:2

the answer cannot be B because 8:6 is not equivalent to 4:2

the answer cannot be C because 6:9 is not equivalent to 4:2

the answer CAN be D because 12:6 is equivalent to 4:2

Answer:

A bouquet of 18 flowers, 12 pink and 6 blue

Step-by-step explanation:

if her total number of children is 3 times the boys, and she has 2 boys that means the equation would be 3b = x(number of children) so that would be 6 children. if she has 2 boys she has 4 girls the ratio is 2 boys: 4 girls meaning that the pink flowers should have more than the blue ones meaning that a bouquet of 18 flowers, 12 pink and 6 blue is the answer
