Step-by-step explanation:

Answer:

a) 2500 L b) 2250 L c) 98000 L d) 14.5 kg of rice, .725 kg of beef, 48.3 repeating kg of wheat.

Step-by-step explanation:

Ok so, this question looks intimidating but I promise it's not that bad.

a) They're asking how much water (L - meaning liters) would be needed for 25 baths.

To find this, they already give you how much water is needed for 1 bath. (100) Since this is the amount for 1 bath, we can find how much water is needed for 25 baths by multiplying 100 by 25. Your answer should be 2500 L of water.

b) This is the same thing again, but with wheat. They give us the information for how much wheat is used for 1 kg of wheat, which is 600 L. The question asks how much water would be needed to produce 3.75 kg of wheat, so we multiply 600 by 3.75 which equals 2250 L.

c) This is also the same thing but this time for beef. So we multiply 40000 by 2.45 which gives us 98000 L

d) To find this, we must divide 29,000 by the amount of water needed for 1 of each item, so we can find how much we would multiply the amount needed for 1 of each item in the first place (which is the amount of rice, beef, wheat)

So, 29,000/2000 = 14.5 kg of rice

29,000/40000 = .725 kg of beef

29,000/600 = 48.3 repeating kg of wheat.

Answer:

they did the horizontal line test.

Step-by-step explanation:

the vertical line test is to see whether or not a graph is a function. you can draw a vertical line at every x-value to see if there are 2 or more points at that x-value. if there are, then it is not a function. however, this student drew a horizontal line instead. this graph is a function, so the student is incorrect. they did the horizontal line test instead of the vertical line test.

Answer: x = 10

Step-by-step explanation:

The value of unknown variable x for the parallel lines AB and CD with given angles is equal to 15°.

Line AB and CD are parallel to each other.

Let us consider EF be the transversal and also consider the intersecting point of AB and CD with transversal such that

A-M-B , C-N-D and E-M-N-F.

Here,

Measure of angle BME = 7x -40°

Measure of angle CNF = 5x -10°

Since line AB and CD are parallel,

use the property that corresponding angles are equal when a transversal intersects two parallel lines.

Angle BME is corresponding to angle CNF.

So, we can set up an equation:

Measure of angle BME = Measure of angle CNF

(7x - 40°) = (5x - 10°)

Now, let's solve for x:

Subtract 5x from both sides:

7x - 5x - 40° = 5x - 5x - 10°

2x - 40° = -10°

Now, add 40° to both sides:

2x - 40° + 40° = -10° + 40°

2x = 30°

Finally, divide by 2:

x = 30° / 2

x = 15°

Therefore, the value of x for the given parallel lines is 15°.

Answer:

The decimal is 0.625

The percent is 62.5%

Step-by-step explanation:

Hi there.

Glad to see you using Brainly!

Equation:

a^2-b^2c^2

Then, multiply the terms with equal exponents.

(We can do this by multiplying their bases)

After:

a^2 - (b c)^2

Now, using a^2 - b^2 = (a-b)(a+b) we factor.

Therefore, after using that we get:

(a-bc) x (a+bc)

Therefore, our solution is

(a - bc) x (a+bc)

Thanks for using Brainly!

Answer:

r and s cannot be parallel

Step-by-step explanation:

If a line intersects two parallel lines, then some special angles are formed between the parallel lines

From the given figure

∵ Line r and line s intersected by line m

∵ m∠1 = 111°

∴ The angle adjacent ∠1 must be 180 - 111 = 69° ⇒ linear pairs

∵ The angle of measure 69° and angle 5 are in the corresponding

   position

∴ m∠5 must be equal 69°

∵ m∠5 = 59° from the given

→ That means the lines cannot be parallel because the angles

   in the corresponding position are not equal in measures.

∴ Lines r and s can not be parallel

Answer:r and s cannot be parallel

Answer:

Three fourths of the theater that is 500 seats is 375 seats.

Your answer is 375 seats.

Step-by-step explanation:

Okay, so to find 3/4 of 500 the first thing you want to do is set up an equation. To find 3/4 of 500 you want to multiply 500 by 3/4 so here's your equation.

x= 500*3/4

An equivalent to this is this equation,

x=500/1 *3/4

To solve this multiply the numerators together then the denominators together.

That would give you,

x=1500/4

Simplify by dividing 1500 by 4 and you get 375.

x=375

So that means that three fourths of the theater that is 500 seats is 375 seats.

In the theater, 500 seats fill 3/4, or 375 seats. An algebraic expression is an expression made up of integer constants, variables, and algebraic operations.

Given,

500 must be multiplied by 3/4 in order to find 3/4 of 500.

x = 500 × 3/4

This can be compared to this equation

x = 500/1 × 3/4

To find the solution, multiply the numerators and denominators together.

After that, you'd have

x = 1500/4.

By multiplying 1500 by 4, you can get 375 by simplifying.

x = 375

Hence, In other words, 375 seats, or roughly one-quarter of the theater's 500 seats, are available.

Answer:

44 questions

Step-by-step explanation:

Part 1: She got 16 questions correct, which was 4/5 of the number of part 1 questions.

Let x = total number of questions in part 1

4/5x = 16

Divide both sides by 4/5

x = 16 ÷ 4/5

= 16 × 5/4

= 20

x = 20

There are 20 questions in part 1

She got 16 questions correct, which was 2/3 of the number of part 2 questions.

Let y = number of questions in part 2

2/3y = 16

Divide both sides by 2/3

y = 16 ÷ 2/3

= 16 × 3/2

= 24

y = 24

There are 24 questions in part 2

The total number of questions on Stephanie’s exam = part 1 + part 2

= 20 + 24

= 44 questions

Answer: 2m^2n.\sqrt{5}  

​

Step-by-step explanation: Factor 20 into its prime factors

          20 = 22 • 5  

To simplify a square root, we extract factors which are squares, i.e., factors that are raised to an even exponent.

Factors which will be extracted are :

          4 = 22  

Factors which will remain inside the root are :

          5 = 5  

To complete this part of the simplification we take the squre root of the factors which are to be extracted. We do this by dividing their exponents by 2 :

          2 = 2  

At the end of this step the partly simplified SQRT looks like this:

        2 • sqrt (5m4n3)  

Rules for simplifing variables which may be raised to a power:

  (1) variables with no exponent stay inside the radical

  (2) variables raised to power 1 or (-1) stay inside the radical

  (3) variables raised to an even exponent: Half the exponent taken out, nothing remains inside the radical. examples:

     (3.1) sqrt(x8)=x4

    (3.2) sqrt(x-6)=x-3

   (4) variables raised to an odd exponent which is  >2  or  <(-2) , examples:

     (4.1) sqrt(x5)=x2•sqrt(x)

    (4.2) sqrt(x-7)=x-3•sqrt(x-1)

Applying these rules to our case we find out that

     SQRT(m4n3) = m2n • SQRT(n)

sqrt (20m4n3) =

       2 m2n • sqrt(5n)  

2 m2n • sqrt(5n)

2(4b - 6) = 4(3b - 7)

This is

8b - 12 = 12b - 28

Now,

16 = 4b

This means that b = 4 :)

Answer:

[tex]\boxed {b = 4}[/tex]

Step-by-step explanation:

Solve for the value of [tex]b[/tex]:

[tex]2(4b - 6) = 4(3b - 7)[/tex]

-Use Distributive Property:

[tex]2(4b - 6) = 4(3b - 7)[/tex]

[tex]8b - 12 = 12b - 28[/tex]

-Take [tex]12b[/tex] and subtract it from [tex]8b[/tex]:

[tex]8b - 12 - 12b = 12b - 12b - 28[/tex]

[tex]-4b - 12 = -28[/tex]

-Add [tex]12[/tex] to both sides:

[tex]-4b - 12 + 12 = -28 + 12[/tex]

[tex]-4b = -16[/tex]

-Divide both sides by [tex]-4[/tex]:

[tex]\frac{-4b}{-4} = \frac{-16}{-4}[/tex]

[tex]\boxed {b = 4}[/tex]

So. therefore, the value of [tex]b[/tex] is [tex]4[/tex].

3x -16 = 65

Add 16 to each side

3x-16+16 = 65+16

3x  = 81

Divide each side by 3

3x/3 = 81/3
