3 painters will paint the room in

3*3/2

= 4.5 hours

Thus the number of hours required are 4.5 hours .

Five friends attend a matinee movie and spend $8 per ticket. They also purchase a small bag of popcorn each. The friends spend a total of $62.50. Let x be the price of a small bag of popcorn.

Part A

Which equation represents the situation?
62.50 + 8x = 40
40 + 8x = 62.50
40 + 5x = 62.50
62.50 + 5x = 40
Part B

How much does each small bag of popcorn cost?

$

Answers

Answer:

Formula: (cost of ticket + cost of popcorn) * # of friends = total cost

Which would give us (8 + x) * 5 = 62.5

Solve for x.

8 + x = 12.5 {divide each side by 5}

x = 12.5 - 8

x = 4.5

Each small bag of popcorn costs $4.50.

hope this helps!

The equation representing the given situation is 40 + 5x = 62.50 and the price of a small bag of popcorn will be $ 4.5. Option C is correct.

What is the equation?

An equation is a statement that two expressions, which include variables and/or numbers, are equal. In essence, equations are questions, and efforts to systematically find solutions to these questions have been the driving forces behind the creation of mathematics.

It is given that, five buddies each pay $8 for a ticket to the matinee. Additionally, they each buy a little bag of popcorn. The pals spend $62.50 altogether.

Suppose x represent the price of a small bag of popcorn.

(cost of ticket + cost of popcorn) × number of friends = total cost

⇒ (8 + x) 5 = 62.5

Simplify the equation to obtain the value of x as

⇒  (8 + x) = 62.5/5

⇒ 8 + x = 12.5

⇒ x = 12.5 - 8

⇒ x = 4.5

Thus, the equation representing the given situation is 40 + 5x = 62.50 and the price of a small bag of popcorn will be $ 4.5. Option C is correct. Option C is correct.

A pyramid has a square base with sides that measure 10cm and a height of 14cm. What is the slant height of the pyramid?
A)17.2 cm
B)14.9 cm
C)13.2 cm
D)12.1 cm

Answers

the answer is A im pretty sure

The solution is,  the slant height of the pyramid is 14.9 meters.

What is Pythagorean theorem?

Pythagorean theorem, the well-known geometric theorem that the sum of the squares on the legs of a right triangle is equal to the square on the hypotenuse (the side opposite the right angle)—or, in familiar algebraic notation, a2 + b2 = c2.

here, we have,

we know that,

The slant height is the height of a triangle making up the base of the pyramid.

We can imagine a right triangle with one leg being a vertical line from the peak of the pyramid going down to the center of the base, and the other leg going from the center of the base to the center of one edge of the base.

And finally, the hypotenuse will join the ends of those 2 lines together and will also be the slant height of the pyramid.

Then we can easily use the Pythagorean theorem to determine the slant height.

So, S = sqrt((10/2)^2 + 14^2)

S = sqrt(5^2 + 14^2)

S = sqrt(25 + 196)

S = sqrt(221)

S = 14.9

So the slant height of the specified pyramid is 14.9 meters.

Use the distributive property with factoring to find the equivalent expression.
27x + 15y = ? (9x + ? y)
Please help! I don't understand!

Answers

Answer:

3;5

Step-by-step explanation:

One side of the equation is 27x + 15y, the number of the first blank times 9x needs to be 27x, so it has to be 3. And 3 times {blank} y needs to be 15y, so the second blank has to be 5.

Hope this helps! :)

Answer:

27x + 15y = 3(9x + 5y)

Step-by-step explanation:

27x + 15y = ?(9x + ?y)

3 times 9 = 27

so the first ? would be 3

27x + 15y = 3(9x + ?y)

15/3 = 5

so the 2nd ? would be 5

27x + 15y = 3(9x + 5y)

Simplify to check your work.

27x + 15y = 3(9x + 5y)

27x + 15y = 3(9x) + 3(5y)

27x + 15y = 27x + 15y
