can someone help the lesson is about ordering.​

Given :

The librarians need to pack 2 tons of books into cardboard boxes. Each box can safely hold about 25 pounds of books. If they already packed 50 boxes.

To Find :

How many more boxes should they expect to use.

Solution :

We know, 1 ton = 2000 pounds

So, 2 ton = 4000 pounds

Minimum number of boxes required for safe handling :

[tex]n=\dfrac{4000}{25}\\\\n=160[/tex]

So, total 160 boxes required.

Therefore, 160 - 50 = 110 many more boxes should they expect to use.

Hence, this is the required solution.

Answer:

110 more boxes

Answer:

4 feet

Step-by-step explanation:

Because if she used 1 feet of ribbon for 3 bows you need to multiply by 4 to 1 foot and you will get 12 bows

Answer:

4 feet of ribbon

Step-by-step explanation:

Because she uses 1 feet of ribbon for each 3 bows, we can create a fraction.

1 ft / 3 bows = x ft / 12 bows

Cross multiplying, we get: 3x = 12

Divide by 3 and we get x = 4 (x in this case is in feet)

Answer:

He would have to do 13 rides.

Step-by-step explanation:

If he initially pays $7, which lets him pay only $1 for each ride, so when he spends $20, he would have done 13 rides.

There are 13 rides will Luka need to ride in order to spend $20.

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

Luka buys a special pass to a fair for $7 that allows him to go on every ride for $1 each.

Here, Luka need to ride in order to spend $20.

Let number of rides = x

So, We can formulate;

⇒ $7 + $1x = $20

⇒ 7 + x = 20

Solve for x as;

⇒ x = 20 - 7

⇒ x = 13

Answer:

3^8 and 6,561

Step-by-step explanation:

1) Calculate, 3 to the power of what is 27?

Make a table of all of 3's powers until 10. i.e. 3^1 = 3, 3^2 = 9 ......

You will find that 3^3 = 27 and 3^5 is 243

3) Use the formula x^m * x^n = x^m+n and substitue our value.

It should look like this: 3^3 * 3^5 = 3^3+5 = 3^8

4) Make a table as described in step 2  and calculate all of 3's powers up to 10. Look at your table and you will find that 3^8 is equal to 6,561

5) The expression written as a power is

3^8 and

the value: 6,561

Answer:

[tex]V=2x^2+8x+8[/tex]

Step-by-step explanation:

The volume of a right rectangular prism is given by :

[tex]V=lbh[/tex]

Where,

l is length, bis breadth and h is height

ATQ,

Height of the cage is 2feet

The length and width are both x feet more than the height.

l = b = (x+2)

So,

[tex]V=(x+2)(x+2)2\\\\V=(x+2)^22\\\\V=(x^2+4+4x)2\\\\V=2x^2+8+8x[/tex]

So, the correct option is (D).

Answer:

Your Ans is

Option D.....

Answer:

The answer is C 2^3

hope this helps!!!

Answer:

2^3

Step-by-step explanation:

Ok, let's jump right in!

Multiply 2^6 by 2^−3 by adding the exponents.

Use the power rule a^m a^n = a^m+n to combine exponents. Therefore, we get:

2^ 6-3

Subtract 3 from 6.

2^3

TIP: For next time remember that when you have to multiply exponents you that have the same base number you really just have to add the exponents.

Given parameter:

Diameter of the ferris wheel  = 80m

Unknown:

Distance covered in one complete rotation = ?

Solution:

One complete rotation will sweep through the circumference of the wheel.

So,

  One complete rotation = Circumference of circle  = 2 [tex]\pi[/tex] r

Where r is the radius;

         Radius here is [tex]\frac{80}{2}[/tex]  = 40m

So circumference = 2 x [tex]\pi[/tex] x 40 = 80[tex]\pi[/tex]

The distance the wheel sweeps through will be 80π m

Answer:

$22.50

Step-by-step explanation:

50/100 = x/45

cross multiply

50 × 45 = 100 × x

2250 = 100x

divide both sides by 100

22.5 = x

*note: marksup the price means that $45 should be more than what the value of x is. $45 is more than $22.50. you can also check your work by looking at the fact $22.50 is exactly half (50%) the amount of $45*

[tex]f(x) = \frac{x}{2} - 2 \\ [/tex]

[tex]g(x) = 2x + {(x - 3})^{2} [/tex]

Step-by-step explanation:

Answer:

The answer is 0.1x-16

Step-by-step explanation:

-3.4x+3x+.5x=0.1x and -25+9 is -16  which is 0.1x-16

Answer:

The roots are;

x = (2 + i)/5 or (2-i)/5

where the term i is the complex number representing the square root of -1

Step-by-step explanation:

Here, we want to use the completing the square method to solve the quadratic equation;

f(x) = -5x^2 + 4x -1

Set the function to zero

0 = -5x^2 + 4x - 1

So;

-5x^2 + 4x = 1

divide through by the coefficient of x which is -5

x^2 - 4/5x = -1/5

We now take half of the coefficient of x and square it

= -2/5^2 = 4/25

add it to both sides

x^2 - 4x/5 + 4/25= -1/5 + 4/25

(x- 2/5)^2 = -1/5 + 4/25

(x - 2/5)^2 = -1/25

Take the square root of both sides

x - 2/5 = √( -1/25

x - 2/5 = +i/5 or -i/5

x = 2/5 + i/5 or 2/5 - i/5

Answer:

if you answer my most recent question ill answer this one.

Step-by-step explanation:

Answer:

9 is the constan trate of change.

Step-by-step explanation:

Assuming two points of the graph with the form as P=(x,y) you can find the constant rate m using the slope formula.  

m=(y2-y1)/(x2-x1)

Lets say that P1=(0,0) and P2=(1,9), then:  

m= (9 – 0)/(1-0)

m=9

Therefore, the point (0,0) means that when you are not buying any t-shirt then you dont have any waste of money. The point (1,9) means that when you are buying one t-shirt then you have to pay 9 then its result that cost of each t-shirt is 9 so when you are buying two t-shirt then you  have to pay 18, when you are buying three you have to pay 27 likewise.

Answer:

There are 10 men in the dance recital.

Step-by-step explanation:

The ratio 2:5 means that for every 5 women there are 2 men.

We will divide 25 by 5 to figure out how many groups there will be.

[tex]25/5=5[/tex]

[tex]x*y=z[/tex]

x = amount of groups.

y = amount of men per group

z = total amount of men.

[tex]5*2=10[/tex]

This means that there are 10 men in the dance recital.

60 pages in 2 days

Step-by-step explanation:

120 pages in 4 days is equivalent to a 30 pages in 1 day rate (divide both by 4). The only other rate that is equivalent to a 30 pages in 1 day rate is 60 pages in 2 days because 60 = 30*2 and 2 = 1*2.

Answer:

60 pages in 2 days is the answer
