A cement mixer can hold up to 681 kilograms of cement. How many 100-pound bags of cement can be put into the mixer at one time?​

Answers

Answer:

15 bags

Step-by-step explanation:

Given that :

Capacity of mixer = 681 kg

Pounds per bag of cement = 100 pounds

Number of bags mixer can hold =?

Converting the capacity of mixer to pounds :

1kg = 2.205 pounds

681 kg = (681 * 2.205) pounds = 1501.605 pounds

Number of 100 pound bag of cement :

Capacity in pounds / 100 pounds

1501.605 / 100

= 15.016

= 15 bags of 100 pound cement

David wants to measure the diameter of his circular pool, but he does not have a tape

Step-by-step explanation:

R=85/2pi

the diameter is 27.07 ft.

What is perimeter?

A perimeter is a closed path that encompasses, surrounds, or outlines either a two dimensional shape or a one-dimensional length. The perimeter of a circle or an ellipse is called its circumference. Calculating the perimeter has several practical applications.

Perimeter refers to the total outside length of an object,

here, we have,

circumference is = 85 feet

now,

diameter = 85/pi

              =27.07

hence, the diameter is 27.07 ft.

slope=4/3 y-intercept=-5

Answers

Answer: 4/3 - 5

I assume you want to know the numbers in slope intercept form so... yeah

Step-by-step explanation

Answer:

The equation of the line in point-slope form is:

[tex]y+5=\:\frac{4}{3}\left(x-0\right)[/tex]

The graph is also attached below.

Step-by-step explanation:

Given

Slope m = 4/3y-intercept = -5

We know that the value of the y-intercept can be determined by setting x = 0 and determining the corresponding value of y.

As we are given the y-intercept = -5

Thus, the point (0, -5) represents the y-intercept.

Point slope form:

[tex]y-y_1=m\left(x-x_1\right)[/tex]

where

m is the slope of the line(x₁, y₁) is the point

In our case,

m = 4/3(x₁, y₁) = (0, -5)

substituting m = 4/3 and the point (0, -5) in the point-slope form

[tex]y-y_1=m\left(x-x_1\right)[/tex]

[tex]y\:-\:\left(-5\right)\:=\:\frac{4}{3}\:\left(x\:-\:0\right)[/tex]

[tex]y+5=\:\frac{4}{3}\left(x-0\right)[/tex]

Therefore, the equation of the line in point-slope form is:

[tex]y+5=\:\frac{4}{3}\left(x-0\right)[/tex]

If n(U) = 125, n(A) = 80, n(B) = 65,
then, greatest value of n(AUB) is​

Answers

Answer:

650,000

Step-by-step explanation:

Given these numbers in the question, multiply all three numbers to get your final answer which is 650,000.

The greatest value of n(AUB) is "145".

An component as well as substance or entity that belongs to both A and B would be included throughout the Union. A union is denoted by "U".

Given:

→ n(U) = 125

→ n(A) = 80

→ n(B) = 65

As we know,

The formula is:

⇒ [tex]n(A \cup B)_{max} = n(A)+n(B)[/tex]

By substituting the given values of n(A) and n(B), we get

                         [tex]=80+65[/tex]

                         [tex]=145[/tex]

Thus the correct answer is n(AUB) = 145.

Answer:

Well 1 litter is already 1000 ml so already its greater

Step-by-step explanation:

6.25 litter is essentially

6250 ml

And 6250>625

Answer:

Yes

Step-by-step explanation:

First we need to know that

1 L = 1000 ml

Using that, we can see that 6.25 L = 6250 ml

(6.25 x 1000, multiply by 1000 to convert from L to ml)

Therefore, 6.25 L (or 6250 ml) is bigger than 625 ml.

help i can't figure this out it's algebra​

Answers

Step-by-step explanation:

Part A:

The maximum point is (2.5, 2531.25). This represents that $2.5 should be decreased from the original price to achieve the most profit from t-shirt sales.

Part B:

The y-intercept is seen to be around (0, 2500). This tells us that the profit made from the original price is $2500.

Part C:

Yes. The point (25, 0) is a solution. It tells us that if we decreased the original price by $25, we would make no/zero profit.

Answer:

Step-by-step explanation:

A. The optimal decrease in price to gain the maximum profit in sale:

Meaning if you reduce the price by $2.5, you will gain the maximum profit of $2531.25

B. It represents the amount of profit without any change in the current price on the t-shirt.

By shifting and expanding the original equation [tex]y=-x^{2}\\[/tex]

[tex]y = -5(x-2.5)^{2} + 2531.25[/tex]

[tex]x = 0 => y = 2500[/tex]

C. The solution is as in part B

It represents by reducing the price of each t-shirt, there is an initial increase in profit but eventually it will drop.

1. If the trapezoid represents 1 whole, what do each of the following shapes represent? Be prepared to show or explain your reasoning.
1. 1 triangle
2. 1 rhombus
3. 1 hexagon

only question 1

Answers

Answer:

Part(A): 1 triangle represents [tex]\dfrac{1}{3}[/tex] of whole.

Part(B): 1 rhombus represents [tex]\dfrac{2}{3}[/tex]  of whole.

Part(C): 1 hexagon represents 2 whole.

Step-by-step explanation:

Consider the provided figure.

Here, it is given that the trapezoid represents 1 whole.

Part 1. Consider figure 1.  

3 triangles can be group into a whole trapezoid.  

[tex]3\times \frac{1}{3}=1[/tex]

Hence, 1 triangle represents [tex]\dfrac{1}{3}[/tex] of whole.

Part 2.

Consider figure 2.  

Here, in figure 2 if we put 1 rhombus on the given trapezoid, we will be left with the shape is a triangle, which is [tex]\dfrac{1}{3}[/tex]  of the trapezoid. Also, the triangle is [tex]\dfrac{1}{2}[/tex] of the rhombus.

We know that 3 triangles can be fit into 1 trapezoid and 2 triangles can be fit on a rhombus

Hence, 1 rhombus represents [tex]\dfrac{2}{3}[/tex]  of whole.

Part 3.

Consider figure 3.  

2 trapezoid = 1 hexagon  

Hence, 1 hexagon represents 2 whole.
