A room is 12 feet long, 14 feet wide, and 11 feet high. The walls, ceiling, and floor are all to be painted the same color. How many square feet must be covered with paint?

Answer:

The denominators of the fractions are 2 and 10.

The fractions with numerators of 1 that have sum of 3 / 5  is calculated below

The sum of the fractions are 3 / 5. Each of the fractions have a numerator of 1. Therefore, let the denominators be x and y

1 / x + 1 / y = 3 / 5

Therefore,

1 / x  + 1 / y = 3 / 5

y + x / xy = 3 / 5

cross multiply

5y + 5x = 3xy

Using hit and trial method,

5(2) + 5(10) = 3(10)(2)

10 + 50 = 60

60 = 60

The values are same.

Therefore, the denominators are 2 and 10.

Answer:

I took the test and got it correct.

The surface area of a cone that has a radius of 5 units and a

height of 10 units is 508.06 square units.

Surface area is the total area of the exposed surfaces of a three-dimensional object. It is the sum of all the areas of the exposed faces of the object, including any curved surfaces. The formula to find the surface area of a cone is A=πr(r+√(h²+r²)).

Given that, radius of a cone is 5 units and the height of a cone is 10 units.

Surface area = 3.14×10(5+√(10²+5²)

= 508.06 square units

Therefore, the surface area of a cone that has a radius of 5 units and a

height of 10 units is 508.06 square units.

Answer:

374 marbles

Step-by-step explanation:

Paul (P) has 1/5 this was given

Shawn (S) has 3/8 this was given

That means Tim (T) must have 17/40 because 1/5 + 3/8 = 23/40 and 1- 23/40 = 17/40

Those are the fractional amounts each boy has. We can set up an equation based on the information in the problem to get the total number of marbles (M). Tim has 84 marbles more than Paul. Thus, Tim has a greater number of marbles. 84 more, to be exact. Our equation would then look like this:

P+84=T

Because we have three unknowns, we need three equations. Thus, we need two more, but we can get them from our fractions at the top.

We need to have a question where we find the total number of marbles.

We know that Paul has 1/5 of the marbles. We can use M to represent the total number of marbles.

P = (1/5)M

T= (17/40)M

We had this from before: P+84=T

If we substitute into the equation:

(1/5)M + 84 = (17/40)M

Now there is only one variable in the equation and we can solve for M.

For M, I got 1120/3 which simplifies to 373 and 1/3, since there cannot be 1/3 of a marble, we can round to 374. There are three hundred, seventy-four marbles in the box.

If you want to check the answer, you can put (1120/3) back in for M in the third equation and you will see that each side is equivalent.

Answer:

Ok ------------------

Answer:

Okay so basically the variables are y and x. Variables in math are just numbers next to a number to represent an unknown number. The coefficient is the number in-front of a variable. The constant would be 5. Think of constants as numbers with variables or negatives or anything. They are pretty much just there. Now as for terms. Terms are just numbers that are part of the equation. Hope this helped!

Answer:

y = 2x + 3

Step-by-step explanation:

Get any two points on the line, say (0, 3) and (2, 7)

Slope = (7 - 3)/(2 - 0) = 4/2 = 2

y = 2x + b

use (0, 3), x = 0, y = 3

3 = b

so the equation is y = 2x + 3

Answer:

Box A is greater than Box B by 34.

Step-by-step explanation:

First, you need to start with finding the surface area of every individual side   on Box A we have side A, B, and C. After finding the individual area for each side,  double each area because there is two of each side. This is the the same method you apply to Box B.

Then subtract the surface area of Box B from Box A.

Answer:

The difference is 21.21%

work shown below

Step-by-step explanation:

I'm going to first find the difference between both.

85-60=25

Now, we have to find 25% of 85

We don't have to use the formula, we can do this in our brain, like this -

We can see that 25% of 80 = 20, since 25 = 1/4, and 1/4 of 80 = 20, then, there is the 5 part left, how do we find that??? well, 25% of 5 = 1.25, since 1.25x5=5,

So hence, our answer is 21.25

Answer:

x = 11.25 and y = 18.75

Step-by-step explanation:

ΔABD ≅ ΔBCD

⇒ 20 : 15 = 15 : x

⇒ 20/15 = 15/x

⇒ x = 15 × 15/20

⇒ x = 11.25

⇒ 25 : 20 = y : 15

⇒ 25/20 = y/15

⇒ y = 25/20 × 15

⇒ y = 18.75

Each person spends 2.53 days showering in a year.

Algebra is a study of mathematical expressions, in which numbers and quantities are represented in formulas and equations by letters and other universal symbols.

Given that,

Time taken by one person to shower = 5 minutes.

Also, one person take shower 2 times in a day.

Total time taken to shower twice per day = 5 x 2 = 10 minutes.

Since, in one year total number of days = 365.

Time taken to shower in 365 days = 365 x 10 = 3650 minutes.

In one day total number of minutes = 24 x 60 = 1440 minutes.

Total days = 3650 / 1440 = 2.534722 days = 2.53

Person showers for 2.53 days in a year.
