If a scientist has two empty breakers that he needs to fill with a certain chemical a three gallon beaker and a five gallon beaker. How can he measure exactly one gallon of the chemical without wasting any?

Answers

Answer 1
He could use the measurements on the sides of the beakers. Most have them. If there are no measurements, measure it into thirds or fifths. Unless you mean something else
Answer 2
He could pour the 5 gallon breaker into the 2 to be left with 3 gallons. He can pour the 2 gallon one out and pour the 5 gallon one into the 2 gallon one again to be left with 1 gallon.

It takes 40 min for a bus to travel the 36 miles from Framingham to Worcester. A car traveling from Worcester to Framingham moves 1.5 times as fast as the bus. If the car and the bus start moving towards each other simultaneously, after how many minutes will they meet?

Answers

First we should find the speed of the bus. v = distance / time v = 36 miles / 40 min v = 0.9 miles per minute The car move 1.5 times as fast as the bus. The speed of the car is (1.5) (0.9 mi / min) = 1.35 mi / min The combined speed of the bus and the car is 2.25 mi / min. That means that they cover a combined distance of 2.25 miles each minutes. We can find the time it takes to cover 36 miles. time = 36 miles / (2.25 miles / min) time = 16 minutes The car and the bus will meet after 16 minutes.

There are 3 islanders fans for every 11 ranger fans. what is the ratio of islander fans to total fans at the game

Answers

So a ratio would be:

variable 1 : variable 2

So in this case, variable 1 would be islander fans, and variable 2 would be total fans.

Total fans would be 3 fans + 11 fans, or 14 fans.

So, it would therefore be:

3:14.

(There would be more fans, but the ratio would still stay the same.)

7b + 4 - 3b - 2

what the number that goes n the box ?

( ? ) b + ( ? )

Answers

4b + 2 is your answer just to help you out if you use cymath you can easily get your answer like i did 

Final answer:

Combine like terms by adding or subtracting the coefficients of terms with the same variable and combining constants. The simplified expression is 4b + 2, so the coefficients that go in the boxes are 4 and 2.

Explanation:

To simplify the expression by combining like terms, follow the process of identifying and adding/subtracting like terms. The expression 7b + 4 - 3b - 2 contains both variable terms (containing 'b') and constant terms (just numbers).

Combine like terms:

Combine variable terms: 7b - 3b = 4b.

Combine constant terms: 4 - 2 = 2.

After combining like terms, the simplified expression is 4b + 2.

Therefore, the numbers that go in the boxes are 4 for the coefficient of 'b' and 2 for the constant term.

Violet is watching the sand in a hourglass drain from the upper portion to the lower portion of the glass. She wonders how fast the sand is draining.

Which unit rates would be reasonable for Violet to use to describe how fast the sand is draining from the upper portion to the lower portion of the glass?

Select EACH correct answer.



gallons per hour

liters per hour

cubic centimeters per minute

cubic inches per second

Answers

Gallons and litters are liquid. Cubic inches per second would be to fast i think so Cubic Centimeters by minute?

The unit rates which will be reasonable for Violet to use to describe how fast the sand is draining from the upper portion to the lower portion of the glass is cubic centimeters per minute.

Explanation:

As the first 2 options gallons per hour and liters per hour, these denote liquid forms. But sand is not liquid that is why it cannot be the answer.

Cubic inches per second is very fast as compared to the small hourglass and the amount of sand that could be present in it. Moreover one side of the hourglass needs to be emptied in 24 hours, so this option is also not possible.

For what value of x will 55 and x have the mean (average) as 67

Answers

if (55 + x)/2 is to be 67, then 55+x = 2*67, so x = 2*67 - 55 = 79
To calculate the mean of two numbers you add them together and divide the sum by 2.
We can set up an equation for this problem: (x+55)/2 = 67

Now we need so solve for x: (x+55) = 67x2
x+55 = 134
x = 134-55
x = 79

how to solve this kind of question?

Answers

96 degrees.

x is the opposite angle to one of the interior angles in the quadrilateral. The interior angles to the quadrilateral are.
1. For the pentagon 180-108 = 72 degrees
2. For the hexagon 180-120 = 60 degrees
3. For the angle with both hexagon and pentagon = 360 - 180 - 120 = 132
4. For the opposite angle to x, since it's the last of the 4 angles in the quadrilateral  will be 360 - 72 - 60 - 132 = 96 degrees

And since x is opposite this 4th angle, it too will have the value 96 degrees.

96 degrees Looking at the diagram, you have a regular pentagon on top and a regular hexagon on the bottom. Towards the right of those figures, a side is extended to create an irregularly shaped quadrilateral. And you want to fine the value of the congruent angle to the furthermost interior angle. So let's start. Each interior angle of the pentagon has a value of 108. The supplementary angle will be 180 - 108 = 72. So one of the interior angles of the quadrilateral will be 72. From the hexagon, each interior angle is 120 degrees. So the supplementary angle will be 180-120 = 60 degrees. That's another interior angle of the quadrilateral. The 3rd interior angle of the quadrilateral will be 360-108-120 = 132 degrees. So we now have 3 of the interior angles which are 72, 60, and 132. Since all the interior angles will add up to 360, the 4th angle will be 360 - 72 - 60 - 132 = 96 degrees. And since x is the opposite (or congruent) angle to this 4th interior angle, it too has the value of 96 degrees.

Thank you! :)

Answers

The statement that is true about the graph is The maximum value of g(x) is greater than the minimum value of f(x).

1. "The maximum value of g(x) is greater than the minimum value of f(x)": This is true because the maximum value of g(x) is -10, which is greater than the minimum value of f(x) (which we don't know, but it cannot be lower than -10 based on the given data).

2. "The minimum value of g(x) is less than the maximum value of f(x)": This is true based on the given data, as the minimum value of g(x) is -1, which is less than the maximum value of f(x) (which we don't know, but it cannot be higher than -1 based on the given data).

3. "The minimum value of g(x) is greater than the maximum value of f(x)": This is false based on the given data. The minimum value of g(x) is -1, which is less than the maximum value of f(x) (which we don't know).

4. "The maximum value of g(x) is less than the minimum value of f(x)": This is false based on the given data. The maximum value of g(x) is -10, which is less than the minimum value of f(x) (which we don't know, but it cannot be lower than -10 based on the given data).

The greatest value of g(x) is -1 (the higher number for the g(x) entry in the table), and the minimum value of f(x) is -3 (the lower y/f(x) you may point on the graph). As a result, the maximum value of g(x) exceeds the minimum value of f(x).

What is the function rule for the line?

A. f(x) = 3/2x - 2

Answers

(-3,0) and (0,-2)

y = -2/3(x) - 2

answer
B. f(x) = -2/3(x) - 2
Let's find the slope-intercept equation of this line.  You can read off the y-intercept immediately; it's the place where x= 0 and the line crosses the y-axis.  Here that intercept is b=-2.

The coordinates of that point are (0,-2).

Now let's find the slope of the line.  Starting at (0,-2) move to the left 3 units (because -3 is the x-coordinate of the intersection of the line with the x-axis).  From (0,-2), how far UP along the y-axis to the x-axis is it?

slope = rise / run.  In this case, starting from (0,-2), and moving 3 units to the left, we get "run" = -3.  Starting from (0,-2) and moving straight up to the x-axis, we get "rise" = 2.

The slope is then m = rise / run   =  2/-3, or    m = -2/3.

Thus, the equation of this line is y = mx + b, or   y = (-2/3)x - 2.

What is Slope of Line?

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is

m=y₂-y₁/x₂-x₁

The charges for two shuttle services are shown in the table.

m=0-10/0.35-0.10

=10/0.25

Ten divided by zero point two five is 10 by one divided by 4.
