Answer 1

Answer:

The number of sandwiches sold is 73. This is because it is multiplied by the expression for the money received per sandwich.

The cost to make each sandwich is S. This is stated in the first sentence of the problem.

The profit is 0.2S. This is because they sell each sandwich for an additional 20% of the cost ( S )

The amount of money the band receives is (S + 0.2S ). This is because it is the price per sandwich.

Answer 2
The amount of sandwiches will is 73 thanks to the Kermit

Find the Surface Area of the Pyramid. Round to the NEAREST TENTH.

Answers

Answer:

465.75 or 465.8 rounded to the nearest tenth

Step-by-step explanation:

You would multiply 16.2 and 14.5 and divide by 2 to get 117.45. You then multiply by 3 for the 3 sides to get 352.35. Lastly, to find the area of the base you would need to multiply 16.2 and 14 and divide it by two to get 113.4. Add it with the 3 sides and you get 465.75.

Answer:

25

Step-by-step explanation:

Let the whole number be W

W x 140% = 35

Percentage to Decimal conversion

Divide % by 100 to get the decimal140/100 = 1.4

Solving

1.4W = 35W = 35/1.4W = 175/7W = 25

Answer:

25

Step-by-step explanation:

We're given:

140% of a number is 35

Let the number be x.

First, convert 140% into a decimal:

1.4

Then, write an equation:

1.4x = 35

x = 35 ÷ 1.4

x = 25

Therefore, 140% of 25 is 35.

4. Each pail of plaster covers 90 square feet of ceiling. What is the least number of pails of plaster you would need to buy to cover the ceiling of a square room with walls 14 feet long?
5 pails
6 pails
4 pails
3 pails

Answers

Answer:

3 pails

Step-by-step explanation:

The square room's base is 14 x 14 = 196

You need to fill the whole room so you might get extra

so... 196 / 90 = 2.177777778

which means you will need  3 and you will have extra

Answer:

3 pails!

Step-by-step explanation:

The area of the ceiling:

A = 14² = 196 ft²

We need plaster to cover 196 ft².

196 : 90 = 2.17778

find the value of x when y equals -7.
2(3x - 7) = 9y​

Answers

Hey there!


2(3x - 7) = 9y

2(3x - 7) = 9(-7)

2(3x - 7) = -63

2(3x) + 2(-7) = -63

6x - 14 = -63

ADD 14 to BOTH SIDES

6x - 14 + 13 = -63 + 13

SIMPLIFY IT!
6x = -63 + 13

6x = -49

DIVISION 6 to BOTH SIDES

6x/6 = -49/6

SIMPLIFY!
x = -49/6

x = -8 1/6


Therefore, the answer should be:

x = -8 1/6 (or x = -49/6 [EITHER OF THOSE SHOULD BE YOUR RESULT BECAUSE THEY ARE BOTH EQUAL TO EACH OTHER])

A coin is tossed several times and the results are displayed in this table.

Heads: 14 Tails: 7

What is the experimental probability of the coin landing on tails?

Enter your answer, as a fraction in simplified form, in the boxes.

Answers

A coin was tossed a total of 21 times.

If we add 7 + 7 + 7 together, we can see that we get 21.

Since 7 + 7 = 14, the probability of getting heads is 2/3.

1 - 2/3 = 1/3, so the experimental probability of the coin landing on tails is 1/3.
