Answer:

$2,000

Step-by-step explanation:

Since B sold the article to C at a gain of 20%, 2,640 must be 120% or 1.2 times the price that B paid.

To find the price that B paid, we just need to divide 2,640 by 1.2, as the original price multiplied by 1.2 = a 20% increase.

2,640/1.2= 2,200

The price B paid for it must have been 2,200.

Now we know that 2,200 was the price sold by A to gain 10%, therefore it is 110% or 1.1 times the original price A paid for it. Therefore, once again to find the original price, we just need to divide it by 1.1:

2,200/1.1 = 2,000

The original price it cost A was $2,000.

Hope this helped!

First, do the prime factorization.

96 = 2 x 2 x 2 x 2 x 2 x 3

72 = 2 x 2 x 2 x 3 x 3

The GCF is the product of their shared factors.

They share 2, 2, 2, and 3.

2 x 2 x 2 x 3 = 24.

Their GCF is 24.

The greatest common factor of the given numbers 96 and 72 will be equal to 24.

The four basic mathematical operations are the addition, subtraction, multiplication, and division of two or even more integers. Among them is the examination of integers, particularly the order of actions, which is crucial for all other mathematical topics, including algebra, data organization, and geometry.

As per the given number for GCF in the question,

Firstly, factorize the given numbers,

96 = 2 x 2 x 2 x 2 x 2 x 3

72 = 2 x 2 x 2 x 3 x 3

The result of their shared factors is the GCF.

2 x 2 x 2 x 3 = 24.

Therefore, the GCF is 24.

Answer:

1.675 lb

Step-by-step explanation:

Given that Hannah mixed 6.83 lb of pretzels with 3.57 lb of popcorn.

So, after mixing, the total amount of mixture is

6.83 lb + 3.57 lb = 10.40 lb.

After filling up 6 bags that were the same size with the mixture, she had 0.35 lb left, so 0.35 lb of the mixture is not in the bag.

So,he total amount of mixture in 6 bags = 10.40 lb - 0.35 lb=10.05 lb, which is the weight of 6 bags.

The weight of one bag =\frac {10.05}{6} lb

=1.675 lb

As all the bags are of the same size, so the weight of all the bags are same,

Hence, the weight of each bag is 1.675 lb.

Hello.

First, "half a number" means we divide that number by 2.

Let's say the number is z.

Divide z by 2:

[tex]\displaystyle\frac{z}{2}[/tex]

Add 5 to it:

[tex]\displaystyle\frac{z}{2} +5[/tex]

Now, this expression equals 11:

[tex]\displaystyle\frac{z}{2} +5=11[/tex]

Subtract 5 from both sides:

[tex]\displaystyle\frac{z}{2} =11-5[/tex]

[tex]\displaystyle\frac{z}{2} =6[/tex]

Now, in order to get rid of the fraction, we should multiply the entire equation by 2:

Answer:

x = 6 cm

Step-by-step explanation:

Volume of a rectangular prism = length × width × height

Length = 5 cm

Width = (x + 12) cm

Height = (x + 6) cm

Volume of a rectangular prism = 1,080 cubic centimeter

Volume of a rectangular prism = length × width × height

1080 = 5 * (x+12) * (x+6)

1080 = 5 (x^2 + 6x + 12x + 72

1080 = 5 (x^2 + 18x + 72)

1080 = 5x^2 + 90x + 360

Divide through by 5

216 = x^2 + 18x + 72

Subtract 216 from both sides

x^2 + 18x + 72 - 216= 0

x^2 + 18x - 144 = 0

Using factorization method to solve the quadratic equation

x^2 + 24x - 6x - 144 = 0

x( x+ 24) - 6 ( x + 24) = 0

(x + 24) (x - 6) = 0

x + 24 = 0

x = -24

x - 6 = 0

x = 6

x = -24 or 6

x can not be a negative value , so, x = 6 cm

Answer:

30000

Step-by-step explanation:

Currently there are 5 significant figures.  Since there is a 5 after the 2, it would round it up to a 3.  Zeros aren't considered significant figures unless there is a period.  Therefore, 30000 is the answer.  3 is the 1 significant figure with four insignificant zeros.

Answer:

30000

Step-by-step explanation:

Remember non-zero numbers are significant.

Zero between non zero numbers are significant.

So 25637 to 1 significant figure is rounding it off to the nearest ten thousand in a simple way.

So 25637 to 1 significant figure simply becomes 30000.

Answer:  y= -1/2x + 5  

Step-by-step explanation:

We will write the equation in slope-intercept form meaning that we will need to find the slope and the y-intercept.

The slope-intercept for is y=mx +b   where m is the slope and b is the y-intercept.

Find the slope by find the difference in the y coordinates and divide it by the difference in the x-coordinates.

The y-coordinates are 3 and 1  

The x coordinates are 4 and 8.

3-1 = 2  

4-8 = -4  

2/-4=   -1/2  

The slope is -1/2  

We will now use one of the points and the slope to find the y-intercept by plotting their values into the formula .

3= -1/2(4) + b

3= -2 +  b

+2  +2

b= 5

The equation will be y= -1/2x + 5

Answer:

D (-1,3)

E (2,2)

F (2,1)

G (-1,0)

Step-by-step explanation:

Multiply each point by 1/5.

Or think of it as dividing each point by 5

D (-5,15) divide -5 by 5 get -1, divide 15 by 5 get 3

so, (-1,3)

The coordinate of the new trapezoid will be D'(-1, 3), E'(2, 2), F'(2, 1), and G'(-1, 0).

Dilation is the process of increasing the size of an item without affecting its form. Depending on the scale factor, the object's size can be raised or lowered. There is no effect of dilation on the angle.

Trapezoid DEFG with vertices D(-5, 15), E(10, 10), F(10,5), and G(-5,0).

The scale factor will be 1/5. Then the coordinate of the new trapezoid will be given as,

D' = (-5/5, 15/5) = (-1, 3)

E' = (10/5, 10/5) = (2, 2)

F' = (10/5, 5/5) = (2, 1)

G' = (-5/5, 0/5) = (-1, 0)

The direction of the new trapezoid will be D'(- 1, 3), E'(2, 2), F'(2, 1), and G'(- 1, 0).

Answer: 56lb

Step-by-step explanation:

Wilma has:

5 small containers that hold 8 lb each: Here we have a total of 5*8lb = 40 lb

6 large containers that hold 12 lb each: Here we have a total of 6*12lb = 72 lb

There is a total of 40lb + 72lb = 112 lb.

Now we know that she uses 4 lb, so now she has:

112lb - 4lb = 108lb.

Now she wants to fill 26 bird feeders, that can hold 2 lb each.

So she needs 26*2lb = 52lb

The amount of bird seeds that she has left is:

108lb - 52lb = 56lb

subtract 15 from both sides:

x=-5

subtract 13 from both sides:

x=38-13

x=25
