Create a proportion using the form = to represent the following word problem.

78% of what number is 42?

Answers

Answer :
x = 53.85

Step by step explanation:
If 78% of x (some numbers) is equal to 42, then we must set this as an equation to find it.

1) Rewriting 78% as a fraction and considering that when we say 78% of some number (x) we mean a product.
78% = 78/100 ➡️ 78/100x = 42

2) Then we can go on :
100 * 78/100x = 42 * 100
78x = 4200
78x/78 = 4200/78 ➡️ x = 53.85

3) Alternatively, simply dividing 42 by 0.78 (78%) would come to the same result :

42/0.78 = 53.85

To get the solution, we are looking for, we need to point out what we know.

1. We assume, that the number 42 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 42 is 100%, so we can write it down as 42=100%.
4. We know, that x is 78% of the output value, so we can write it down as x=78%.
5. Now we have two simple equations:
1) 42=100%
2) x=78%
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
42/x=100%/78%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 78% of 42

42/x=100/78
(42/x)*x=(100/78)*x - we multiply both sides of the equation by x
42=1.28205128205*x - we divide both sides of the equation by (1.28205128205) to get x
42/1.28205128205=x
32.76=x
x=32.76

Answers

Answer:

Step-by-step explanation

its really simple u replace the letter with the value they have given u

t= 6

= 6x6-20-32u

u=1/4

=36-20-32x1/4

Hey, so in this case, the variable are t and u.
They gave you the numbers that each variable represents. Which are:
t=6 and u=1/4
So now what you need to do is, replace the variables with the numbers they represent in the equation. So it’s gonna be:
6(6)-20-32(1/4)
So now use PEMDAS to calculate. PEMDAS (parentheses - exponents - multiplication - decision - addition - subtraction)

So multiply 6 with 6, and then multiple 32 with 1/4.
36-20-8
Now subtract to get the answer.

Answer:
36-20-8= 8

The answer is 8

Gloria wants to make beef stroganoff for 12 people. Her recipe serves 8 people and calls for 4.5 pounds of ground beef. How much ground beef should Gloria purchase?

Answers

Answer:

6.75 pounds

Step-by-step explanation:

This question is of direct variation. We will use x as our answer. 8 is 2/3 of 12, so 4.5 should be 2/3 of x. We can now make an equation.

In order to solve the equation, we multiply both sides by the reciprocal of 2/3, which is 3/2.

* stands for multiplication

From solving our equation, we get 6.75. We can't forget the units, so the answer is 6.75 pounds.

the area of a base of a cylindrical water tank is 12π square feet. the volume of water in the tank is dependent on the height of the water (h) and is represented by the function V(h) = 12π h
part a - find V to the power of -1 (h)
part b - what will the height of the water be when the volume reacher 420π cubic feet

Answers

Answer:

Step-by-step explanation:

V^－1(h)is find inverse function=h / 12π

V=12πh=420π

h=420π/12π=35 feet

The inverse of the function V(h) is V⁻¹(h) = h / (12π). And the height of the water is 35 feet.

What is the volume of a right circular cylinder?

Let r be the radius and h be the height of the cylinder. Then the volume of the cylinder will be given as,

V = π r²h cubic units

A cylindrical water tank's base measures 12π square feet. The volume of water in the tank is proportional to its height (h) and is represented by the function V(h) = 12π h.

The inverse of the function V(h) is given as,

h = 12π V⁻¹(h)

V⁻¹(h) = h / (12π)

If the volume is 420π cubic feet. Then the height of the water is given as,

420π = 12π h

h = 420π / 12π

h = 35 feet

The inverse of the function V(h) is V⁻¹(h) = h / (12π). And the height of the water is 35 feet.

Answers

Answer: 5x + 16

Step-by-step explanation: distribute, add the numbers, and combine like terms.

Answer:

x = -3.2

Step-by-step explanation:

First, solve parenthesis:

2(x+6)+3x+4= 0 (Given)

2x + 12 + 3x + 4 = 0 (distributive property of equality)

Then, you comibine like terms:

2x + 12 + 3x + 4 = 0

5x + 16 = 0 (Combining like terms)

And then, move the variables to the left and constants to the right:

5x + 16 = 0

5x = -16 (Subtraction property of equality) You subtract 16 from both side, since the variable is on the right already you leave it that way.

Finally, you divide both sides to get the answer ( solve for X):

5x = -16

x = -3.2 (division property of equality)

There is your answer!

Answer:

Step-by-step explanation:

y=mx+b

first identify "b", which is where the line crosses the y-axis, in the graph we can see it does so at unit 3.

b= 3

next, we will find where the line crosses any point on the graph perfectly, such as coordinate (1, 7). Now use unit 3 on the y-axis as your reference point, we can see coordinates (1, 7) is 4 units up and 1 unit to the right from our reference point. This indicates our "m",

m= 4/1

therefore, y=4/1x+3
