Sam’s Soups is open 6 days a week, 76 hours in all. Its hours are the same every day, except on Saturday and Sunday. On those days, it is open 2 hours longer. How long is Sam’s Soups open on Sunday? Use an equation to solve.

Answers

Answer:

14 hours

Step-by-step explanation:

Let x be the number of hours open on each of the four days (because it is six days per week) that are not Saturday or Sunday. Thus, the total number of hours on those days would be 4x. Then, we are told that Sam's Soups are open 2 hours longer on Saturdays and Sundays, so that would be x + 2. There are two of those days, so that would be 2(x + 2). Since all of these hours total 76, we have our equation:

4x + 2(x + 2) = 76

4x + 2x + 4 = 76

6x = 72

x = 12

Remember, 12 hours is the number of hours that Sam's Soups is open on days that are not Saturday and Sunday. Those days are x + 2. Thus, that is 12 + 2 = 14 hours.

Answer:

14 hours

Step-by-step explanation:

x = hours on day other than saturday and sunday

y = hours on Saturday and Sunday.

Sam's soups are only open 6 days a week, and 2 are weekends, so it is only open on 4 weekdays.

4x + 2y = 76

We know the hours on Saturday and Sunday are 2 hours more than the weekday hours.

So,

y = x + 2

Substituting that back into the original equation,

4x + 2(x+2) = 76

4x + 2x + 4 = 76

6x = 72

x = 12

y = 14

So Sam's Soups is open 14 hours on Sunday.

Julia decides to sell the baskets she doesn’t have room for. If she bought each of them for $8.50 and sells them for $12, what is percent of markup? What is her overall profit?

Answers

Given:

Cost = $8.50,Selling price = $12.00.

Find markup:

$12.00 - $8.50 = $3.50

Percent of markup:

3.50/8.50 × 100% = 41.18% (rounded)

The number of baskets is not given. If it is x, then total profit is:

3.5x dollars

Given:

Cost = $8.50,

The selling price = is $12.00.

Find markup:

$12.00 - $8.50 = $3.50

Percent of markup:

3.50/8.50 × 100% = 41.18% (rounded)

The number of baskets is not given. If it is x, then the total profit is:

3.5x dollars

Answers

Answer:

add all the sides

Step-by-step explanation:

The easiest way to solve this is creating two shapes; cut the top off so it's a square-like shape, and you'll also have the long rectangle at the bottom.

the first shape's area is 3.8 x 4 = 15.2

the second is 13.05 x 3.6 = 46.98

since originally it's one shape, add them together. the area is 62.18 ft^2.

A toy company's total payment for salaries for the first two months of 2012 is $40,765. Write and solve an equation to find the salaries for the second month if the first month’s salaries are $10,205.

Answers

Answer:

its D

12,455 + x = 23,894

x = 10,560

Step-by-step explanation:

Let's say that the variable 'x' represents the salaries for the second month, so out equation would be:

10,205 + x = 23,894

To solve, we must isolate the variable by subtracting 12,455 from both sides:

10,205 + x = 23,894

-10,205        -10,205

x = 10,560

So, the second month's salary was $10,560

Step-by-step explanation:

Answer: x = $30,560

Step-by-step explanation:

1. Let the second month payment be x

2. The first month + The second month = both of the months

3. So substituting: 10,205 + x = 40,765

4. Subtract 10,205 from both sides: x = 30,560

54 servings of the chili were sold.

The number of cups of chili that he sold will be will be 90 cups. Then the number of servings of the chili sold will be 54.

What is the percentage?

The amount of any product is given as though it was a proportion of a hundred. The ratio can be expressed as a quarter of 100. The phrase % translates to one hundred percent. It is symbolized by the character '%'.

A chef made 150 cups of chili and sold 60% of it. Then the number of cups of chili that he sold will be calculated as,

⇒ 60% of 150

⇒ 0.60 x 150

⇒ 90 cups

The serving size of the chili is 1 ²/₃ cups.

Convert the mixed fraction number into a fraction number, then we have

1 ²/₃ cups = 1 + 2/3

1 ²/₃ cups = 5/3 cups

Then the number of servings of the chili sold will be calculated as,

⇒ 90 / (5/3)

⇒ 90 x (3 / 5)

⇒ 18 x 3

⇒ 54

The number of cups of chili that he sold will be will be 90 cups. Then the number of servings of the chili sold will be 54.

What is 5,890,000 in Scientific Notation?

Answers

Answer:

5.89 x 10^6

The purpose of scientific notation is for scientists to write very large, or very small, numbers with ease.

Calculating scientific notation for a positive integer is simple, as it always follows this notation:

a x 10b

Follow the steps below to see how 5,890,000 is written in scientific notation.

To find a, take the number and move a decimal place to the right one position.

Original Number: 5,890,000

New Number: 5.890000

count how many times you moved the decimal and that's your power

in this case it's ^6

It’s 5.89 X 10^6. This is, in England, called standard form. It’s how really large numbers are represented in a small way.

Which expression can be used to find the surface area of the triangular prism? Will give Brainliest!

Answers

Answer:

C

Step-by-step explanation:

It is usually A= 1/2 B*H which 1/2*3*4 in parentheses would fit this, but im not 100% sure!

We are given the dimensions in the net drawing (the two-dimensional image of the shapes used to create the triangular prism). Let’s list the information we have:

• We have two congruent right triangles with bases=3 and heights=4

• 3 Rectangles, which all share the same width: width=2

Since we are dealing with two-dimensional figures, we must use the area formulas for them.

Area of triangle:

A=1/2•B•H

Area of a rectangle:

A=L•W

Because we have two congruent triangles, their areas must be congruent, too. So, we have double the area of one triangle. So, we can modify the formula:

A=2(1/2•B•H)

Because all three rectangles share the same width but have different lengths, we can add their lengths together to form one whole rectangle.

4+3+5=12

So, all three rectangles’ sides have been combined (added) to form one whole rectangle with the dimensions:

12 by 2.

Now, because the surface area is the total area used to form the faces of a 3-D shape, we must add all the areas of the figures together.

Area of a triangle (modified)

A=2(1/2•3•4)

Area of rectangle:

A=12•2

Simplify:

Triangle:

A=2(6)

A=12

Rectangle:

A=12•2

A=24

Now, let’s add the areas together:

12+24=36

So, the surface area is 36ft^2.

Now, to answer the question, option 3.) is correct

A: 2(1/2•3•4)+4•2+3•2+5•2

Mr. Chin asked his class to solve for y in the equation 8(3y - 5) = 9(y - 5) -1. Explain how to solve for y. Then solve.

Answers

Answer:

[tex]\Huge \boxed{\boxed{\bf{y = -\frac{2}{5} }}}[/tex]

Step-by-step explanation:

To solve for [tex]\tt{y}[/tex] in the equation [tex]\tt{8(3y - 5) = 9(y - 5) - 1}[/tex], we'll need to simplify and isolate the variable.

Let's start by distributing the 8 on the left side and the 9 on the right side of the equation:

[tex]\tt{8(3y - 5) = 9(y - 5) - 1}[/tex][tex]\tt{24y - 40 = 9y - 45 - 1}[/tex]

Next, we'll combine like terms on both sides of the equation:

[tex]\tt{24y - 40 = 9y - 46}[/tex]

To isolate the variable, we'll move all the terms involving y to one side of the equation. Let's subtract 9y from both sides:

[tex]\tt{24y - 9y - 40 = 9y - 9y - 46}[/tex]

Simplifying further, we have:

[tex]\tt{15y - 40 = -46}[/tex]

To isolate "y," let's add 40 to both sides:

[tex]\tt{15y - 40 + 40 = -46 + 40}[/tex]

Simplifying, we get:

[tex]\tt{15y = -6}[/tex]

Finally, we can solve for "y" by dividing both sides of the equation by 15:

[tex]\tt{\frac{15y}{15} = \frac{-6}{15}}[/tex]

Simplifying the equation, we have:

[tex]\tt{y = -\frac{2}{5} }[/tex]

So, the solution to the equation is y = -2/5.

Sam's Soups is open 6 days per week, 76 hours altogether. Its hours are similar consistently, besides on Saturday and Sunday. On those days, it is open 2 hours longer.

Let 'x' be the number of hours spent on Saturday and Sunday. Then the equation is given as,

x + x + (x - 2) + (x - 2) + (x - 2) + (x - 2) = 76

Simplify the equation, then we have
