To calculate the cost per cup of bleach, first convert the quantity from gallons to cups. A 3-gallon bottle equals 48 cups. Divide the total cost ($13.92) by the total number of cups (48) to determine the cost per cup, which is $0.29.

This problem involves finding out the unit cost or, in this case, the cost per cup of bleach. One gallon is equivalent to 16 cups, hence a 3-gallon bottle is equivalent to 48 cups.

So, if $13.92 buys you 48 cups, you can calculate the cost per cup by dividing the total cost by the number of cups.

Proceed with the following calculation: $13.92 costs /48 cups = $0.29 per cup of bleach costs.

In conclusion, each cup of bleach from this 3-gallon bottle would cost you $0.29.

To find the price per cup of bleach from a 3-gallon bottle costing $13.92, we multiply 3 gallons by 16 cups per gallon to get 48 cups, and then divide $13.92 by 48 to find the cost per cup, which is approximately $0.29.

To calculate the price per cup of bleach when given the price per gallon, we need to know how many cups are in a gallon and then divide the total cost by the total number of cups.

First, we establish that there are 16 cups in a gallon. Since we are dealing with a 3-gallon bottle, the total number of cups will be 3 gallons times 16 cups per gallon, which equals 48 cups.

Next, we take the total cost of the 3-gallon bottle, which is $13.92, and divide it by the total number of cups, 48. Performing this division gives us the cost per cup. So, $13.92 divided by 48 cups equals approximately $0.29 per cup.

This method demonstrates how to break down bulk costs into more manageable unit prices and can be applied across various products and measurements.

Answer:

$0.036

Step-by-step explanation:

I will be solving this questions in a rational, proportional way.

This question given is directly proportional. There are two types of proportion.

Direct - Let's say there are two values, x and y. In direct proportion, while x   increases, y increases with it.  

Inverse- Taking x and y, in inverse proportion, while x increases, y decreases or while y increases, x decreases.

In the given example, there are two values, number of plates and cost of plates. While the number of plates increases, the cost would surely increase. Therefore, giving us that it is a direct proportion.

500 plates : $18.00 :: 1 : $x

500 plates is to 18 dollars, then, 1 plate is to how many dollars?

In direct proportion, the product of extremes is equal to the product of means.

500(x) = 18(1)

500x = 18

x = 18 / 500

x = 0.036

Hence, one plate costs $0.036 or 3.6 cents

Answer:

each plate cost:  .036 each

18.00 divided by 500

Answer:

The discriminant is -23 and the equation has no real roots.

Step-by-step explanation:

Since, the discriminant of the quadratic equation [tex]ax^2+bx+c=0[/tex]

is,

[tex]D=b^2-4ac[/tex]

If D > 0, then the equation has two distinct real roots,

if D = 0, then the equation has two equal real roots,

if D < 0 then the equation has no real roots,

Here, the quadratic equation is,

[tex]x^2+3x+8=0[/tex]

Discriminant,

[tex]D=3^2-4\times 1\times 8=9-32 = -23 < 0[/tex]

Therefore, the discriminant is -23 and the equation has no real roots.

let's bear in mind that 1 Cup = 8 fl oz.

a) is absolutely correct, 18oz and thus they can fit fine in the 24oz container.

b) is correct, 24 - 18 = 6, we can fit in 6 more oz, which is 3/4 of a cup.

c) is correct as well

d)

we just need to convert c) units to fluid ounces

Answer:

C, and D are both roots of this equation

Answer:

The two values of x that are roots are:

[tex]x_{1} = \frac{-3 + \sqrt{21} }{2}[/tex]

[tex]x_{2} = \frac{-3 - \sqrt{21} }{2}[/tex]

Step-by-step explanation:

A cuadratic function has the form [tex]ax^{2} + bx +c = 0[/tex]

To calculate the roots of the cuadratic equation [tex]x^{2} + 3x -3 = 0[/tex] you have to solve the formula:

[tex]x = \frac{-b}{2a}[/tex] ±[tex]\frac{\sqrt{b^{2} -4ac} }{2a}[/tex]

In this case, a =1, b=3 and c= -3

Replacing the values of a,b and c in the formula:

[tex]x = \frac{-3}{(2)(1)}[/tex] ± [tex]\frac{\sqrt{(3)^{2} - (4)(1)(-3) } }{(2)(1)}[/tex]

Solving the mathematic operations:

x = [tex]\frac{-3}{2}[/tex] ± [tex]\frac{\sqrt{9 + 12 } }{2}[/tex]

The two roots are:

[tex]x_{1} = \frac{-3 + \sqrt{21} }{2}[/tex]

[tex]x_{2} = \frac{-3 - \sqrt{21} }{2}[/tex]

Answer:

A. A tennis tournament in which after each round, half the players are eliminated.

Step-by-step explanation:

Answer:

1/2x-5=13

Step-by-step explanation:

Let x= Frankie’s mother’s age

Half his mother’s age= 1/2x

5 less than that=1/2x-5

We know that Frankie is 13 so that equation is equal to Frankie’s age, which is 13.

Hope this helps.

To determine Franky's mother's age, we can create an equation using the given information. By solving the equation, we find that Franky's mother is 36 years old.

To determine Franky's mother's age, we can create an equation based on the given information. Let's assume Franky's mother's age is M. According to the information given, Franky's age is 5 years less than half of his mother's age. So, Franky's age can be represented as (1/2)M - 5.

We are also given that Franky is 13 years old. So we can set up the equation:

(1/2)M - 5 = 13

To solve for M, we can simplify the equation:

(1/2)M = 13 + 5

(1/2)M = 18

M = 18 * (2/1)

M = 36

Therefore, Franky's mother's age is 36 years old.

Answer: 432ft. shadow

Step-by-step explanation:

Because Nora is 5’3”, you need to convert every numerical value into inches by multiplying them by 12 (12in = 1 ft.)

5’ x 12 = 60” + 3” = 63”

9’ x 12 = 108”

252’ x 12 = 3,024”

Then create equivalent fractions.

63/108 = 3,024/x

108 x 3024 = 326,592/63 = 5,184in.

Then convert it back into feet.

5,184/12 = 432ft.

Final answer:

Using the proportion of similar triangles, we find that if Nora, who is 63 inches tall, casts a 108-inch shadow, then the 3024-inch tall monument will cast a shadow that is 5184 inches long, or 432 feet.

Explanation:

To find the length of the shadow casted by the monument, we can use the concept of similar triangles. The proportion between the heights and shadows of Nora and the monument will be the same because the angle of the sunlight is the same for both. Nora is 5'3" tall, which is 63 inches, and she casts a 9-foot shadow, which is 108 inches. The monument is 252 feet tall, which is 3024 inches. Setting up the proportion, we have:

Nora's height : Nora's shadow = Monument's height : Monument's shadow

63 inches : 108 inches = 3024 inches : x inches

To solve for x (the length of the monument's shadow in inches), we cross-multiply and divide:

63 * x = 3024 * 108

x = (3024 * 108) / 63

x = 5184 inches

To convert this back to feet, we divide by 12 inches per foot:

x = 5184 inches / 12 inches/foot

x = 432 feet

Therefore, the length of the shadow cast by the monument is 432 feet.

Step-by-step explanation:

We want to model the position of the submarine as a function of time.

Notice that we have a constant amount. The initial depth: 750 meters

 Then we have a factor that varies over time. Every hour the submarine ascends 50 meters. therefore as t increases the depth y(t) of the submarine decreases. Then the factor is:

-50t.

Where t represents the time in hours.

Then the equation that represents the new position of the submarine in relation to the level of the sea:

Answer:

Option A.

Step-by-step explanation:

The graph below shows the transformation from triangle 1 to triangle 2 as below.

1). To understand the transformation we will take a point A. Present coordinates of point A are (1, -1).

When point A is reflected across y - axis, coordinates of A' become (1, 1).

2). Now we see that triangle 2 is in 3rd quadrant having coordinates A"(-1, -1)

which reveals that A'(1, 1) has been rotated by 180° counterclockwise.

Therefore, option A. is the correct choice.

Answer:

Angles in a triangles add up to 180°

Respectively 1 : 2 : 3 is going to be 1 x , 2 x and 3 x so,

1 x + 2 x + 3 x = 180°

⇒ Simplify

6 x = 180°

⇒ Divide by 6 on both sides to isolate x

x = 30°

Since the ratio was 1 x : 2 x : 3 x and x is 30°,

30 : 60 : 90

And since there is a 90° angle, it is a right - angled triangle
