Find the sum of all the natural numbers from 1 and 400, inclusive, that are not divisible by 11.

Answers

Answer: 72874

Step-by-step explanation:

To solve this, you can first find the sum of all numbers from 1 to 400. Using the formula for arithmetic series, you can get 1+2+3+4...+400=80200. Then, you can subtract all multiples of 11 from 1 to 400. That is 11+22+33+44+...+396. Dividing all numbers by 11, we have the new arithmetic series 1+2+3+4..+36, which using the formula, equals 666. Multiply this by 11 to get 7326 and subtract from 80200 to get 72874.

Two stores advertise a discount on the same type of watch. At both stores, the original price of the watch was $35.00

Store A discounts the price of the watch by 20%
Store B discounts the price of the watch by 15%

How much less is the discounted price of the watch at store A than the discounted price of the watch at store B?

Answers

store A would pay: $28
store B would pay: $29.79

The correct discounted amount of store A compared to store B is $1.79

Store A has $ 1.75 less discounted price than Store B.

What is Percentage?

To determine the quantity or percentage of something in terms of 100, use the percentage formula. Per cent simply means one in a hundred. Using the percentage formula, a number between 0 and 1 can be expressed. A number that is expressed as a fraction of 100 is what it is. It is mostly used to compare and determine ratios and is represented by the symbol %.

Given:

The original price of the watch was $35.00

Store A:

Discount = 20%

So, price after discount = 35 - 35 x 0.20

                                       = $28

and, Store B:

Discount = 15%

So, price after discount = 35 - 35 x 0.15

                                       = $29.75

Hence, Store A has $ 1.75 less discounted price than Store B.

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.

Step-by-step explanation:

You want the equations for the inequalities shown on the graph.

Line A

The downward sloping dashed line crosses the y-axis at y=3. It has a "rise" of -2 units for each 1 unit to the right. Its slope is rise/run = -2/1 = -2.

The equation for this boundary line can be written ...

Line B

The upward sloping solid line crosses the y-axis at y=0 and has a rise of 1 for each run of 1 unit to the right. Its slope is 1/1 = 1, and its y-intercept is 0.

The equation for the boundary line can be written ...

  y = 1x +0

The graph is shaded below the solid boundary line, so the boundary is included in the solution. The inequality graphed is ...

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

what is the answer for 5/11x + 2/3x - 1/6x = -189

Answers

Answer:

x = -198

Step-by-step explanation:

5/11 x + 2/3 x - 1/6 x = -189

66(5/11x + 2/3x - 1/6x) = 66(-189)

30x + 44x - 11x = -12474

63x = -12474

x = -198

Answer:

x = -210

Step-by-step explanation:

[tex]\frac{5}{11x} + \frac{2}{3x} - \frac{1}{6x} = -189[/tex]

[tex]\frac{37}{33x} - \frac{1}{6x} = -189[/tex]

[tex]\frac{21}{22x} = -189[/tex]

The average weight of five cats is 5.2 kg. The weights of four of the cats are 5.4 kg, 5 kg, 4.8 kg, and 4.9 kg. Find the weight of the fifth cat.

Answers

Answer:

5.9 kg

Step-by-step explanation:

Remember! To find the average of things, you add them al up and divide by how many things there are. This is an important detail that will help us solve the problem

It says the average is 5.2
This means ...

( weight of cat 1 + cat 2 + cat 3 + cat 4 + cat 5 ) ÷ 5 = 5.2

Let's plug in all of the values we know to find the weight of cat 5

( 5.4 + 5 + 4.8 + 4.9 + CAT 5 ) ÷ 5 = 5.2

Let's add all of this up and solve this!

( 20.1 + CAT 5 ) ÷ 5 = 5.2

multiply 5 by both sides so we can get the weight of cat 5 alone

20.1 + CAT 5 = 26

subtract

CAT 5  = 26 - 20.1

CAT 5 = 5.9

the weight of cat 5 is 5.9 kg

answer:
The weight of cat five is 5.9g

Answer:

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

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.
