1.7 hours
6.7 hours
.5 hours
2.3 hours

Answers

Answer:

1.7

Step-by-step explanation:

in one hour, the first pump can fill the tank 1/4 of the way

in one hour, the other can fill it 1/3 of the way.

What is a solution set to an inequality or an equation?

If the equation or inequality contains variable terms then there might be some values of those variables for which that equation or inequality might be true.

Such values are called solution to that equation or inequality.

So, Set of such values is called solution set to the considered equation or inequality.

If x and y are real numbers such that x > 0 and y < 0,

We need to find the inequalities that must be true for the given situation;

Hence, |x|^2 >|y| could be the correct option.

When we put a number such that x > 0 and y < 0, then this holds true.

So Option 3 is answer.

What is reflection?

A reflection is a type of transformation that involves flipping a shape, known as the preimage, across a line, known as the line of reflection, to produce a new shape (called the image). You can picture what would happen if you turned the form across the line to graph a reflection.

Reflection is a type of transformation that flips a shape along a line of reflection, also known as a mirror line, such that each point is at the same distance from the mirror line as its mirrored point.

Given:

The Rule for reflection is  (x,y) =(x,-y).

As, the coordinates C(2, 3).

Now, after applying the reflection the coordinate of C become

c(2, 3) ----> C(2, -3).

Hence, the coordinates of C(2, -3).

A paper company needs to ship paper to a large printing business. The paper will be shipped in small boxes and large boxes. Each small box of paper weighs 25 pounds and each large box of paper weighs 70 pounds. A total of 21 boxes of paper were shipped weighing 1110 pounds altogether. Write a system of equations that could be used to determine the number of small boxes shipped and the number of large boxes shipped. Define the variables that you use to write the system.

Answers

Answer:Number of small boxes shipped = 8

Number of large boxes shipped = 13

Step-by-step explanation:

Step-by-step explanation:

Let x be the number of small boxes and let y be the number of large boxes

According to the first statement, a total of 21 boxes were shipped

Equation 1 will be:

x+y=21

According to 2nd statement, the total weight was 1110 and we know the weight of one small box is 25 and large box is 70

Equation 2 will be:

25x+70y=1110

Use the substitution method for solving the equation

Putting the value of x in equation 2  

25(21-y) +70y =1110

525-25y+70y = 1110

45y = 585

Y=13

Putting the value of y in equation 1  

x+13 = 21

X = 8

Number of small boxes shipped = 8

Number of large boxes shipped = 13

Use the scenario and table to determine which statements are true. Check all that apply.

Armand and Jill will each travel the same distance to meet.
Armand and Jill will travel the same amount of time to meet.
The equation used to find the time, t, it will take for them to meet is 50t + 60t = 247.5.
It will take 4.5 hours for them to meet.
