Find the value of x and y

Answer:

speed = 7.5 miles per hour

Step-by-step explanation:

To find the speed, we divide the distance by the time

speed = distance/time

speed = 15miles/2 hours

speed = 15/2 miles per hour

speed = 7.5 miles per hour

express the equation in slope-intercept form: f(x) = mx + b.

Here's a general outline of the process we'll follow once I have the graph:

Identify key features:

Slope: Determine the slope of the line, which signifies the rate of change of the function. You can calculate it using the formula slope = (change in y) / (change in x) between any two points on the line.

Y-intercept: Locate the point where the line intersects the y-axis. This point is crucial for determining the function's vertical shift.

Apply slope-intercept form:

Once you have the slope (m) and y-intercept (b), express the equation in slope-intercept form: f(x) = mx + b.

Verify with points:

Choose a few points on the graph and substitute their coordinates into the equation to ensure it accurately represents the line.

Answer:

2 and 1/4 or 2.25. Both numbers are the same.

Step-by-step explanation:

Hi,

Please see the picture I had to upload in order for this question to be complete. Please also note that Kara has 3 buttons in the 3/4 length. You have to sum up only those in that length and ignore the ones in different lengths.

It is a very simple multiplication, and there are 2 ways to do so. You can use either fractions or integer numbers. See the 2 options below:

3/4 (fractions) = .75 (integer numbers)

Option one - 3 * 3/4 = 9/4 which is represented by 2 and 1/4.

Option two - 3 * .75 = 2.25

Have a good one!

To determine the remaining fraction of juice in the bottle, subtract the poured amount from the original 20 ounces. The fraction left in the bottle is 3/5 of the original 20 ounces.

To find the fraction of juice left in the bottle:

Start with 20 ounces.

Pour out 1/4 for a friend, which is 5 ounces (1/4 of 20).

Pour out 3 more ounces for yourself.

Subtract the total poured out (5 + 3 = 8) from the starting amount (20) to find what's left.

So, 20 - 8 = 12 ounces left in the bottle, which represents 3/5 of the original 20 ounces.

Answer: 10%, 0.5, 3/4

Step-by-step explanation:

What you want to do is convert them all to one unit. The eaisest would be a decimal.

Starting off with .5, it's already in decimal form.

Next go to 10%. 10% as a decimal will be 0.1, because its 1/10.

Lastly, go to 3/4. 3/5 as a decimal would be 0.75.

Putting them in order from least to greatest would be 10%, 0.5, 3/4.

(Hope that helps)

Answer:

10%, 0.5, 3/4

Step-by-step explanation:

This is actually quite simple, all you need is a quick calculation.

I'm going to convert all of the numbers to decimals for the easiest comparison.

put 3/4 into a calculator, and you get 0.75

0.5 is already a decimal

and with percents, you just move the decimal point back two, making it 0.1

Now you have an easy way to compare: 0.1 is the least, 0.5 is next, the 0.75 is the largest.

Answer:

The first pair of events are independent, the second pair of events are independent and the third pair of events are dependent.  

Step-by-step explanation:

Independent events are events that do NOT rely on previous events.  So, the chances of each of event happening in a pair of events is independent, or has no effect, on the chances of the other event.  In the case of rolling a number cube and then rolling it again, your chances would be the same each time you roll the number cube as to what number you would get.  Just because you rolled a '1' on the first roll, doesn't mean you can't get the same number (or another number) on another roll.  The same reasoning applies to the coin flip and the spinner.  These two events are not related and in no way would rely on each other.  A coin flip will not affect the chances of spinning an odd number.  However, if we have several coins in a bag and select a quarter, but do not replace it, our chances of selecting another coin changes because there are not only less coins in the bag, but there are less quarters to choose from.  In the case of events with NO replacement, these events are dependent.

c + p = 90

Charlie gave 1/4 c to Peter.  Now

Charlie has c - (1/4) c

Peter has p + (1/4) c

Peter gave 2/5 of his to Charlie. Now

Peter has p + (1/4) c - 2/5( p + (1/4) c )

Charlie has c - (1/4) c + 2/5( p + (1/4) c )

And then they had equal number:

c - (1/4) c + 2/5( p + (1/4) c ) = p + (1/4) c - 2/5( p + (1/4) c )

Let's do the easy subtractions then multiply by 20 to clear the fractions,

(3/4) c + 2/5( p + (1/4) c ) = 3/5( p + (1/4) c )

15c + 8p + 2c = 12p + 3c

14c = 4p

7c = 2p

c + p = 90

2c + 2p = 180

2c + 7c = 180

9c = 180

c = 20

p = 70

The midsegment is basically the average of the two parallel sides

Answer:

C. Cost of peanuts purchased

Step-by-step explanation:

The range is the values that the y variable, or the output can take.

The output is the cost of the peanuts

5x - 7y =58

y =-x +2

Using the substitution method, replace y in the first equation with the second equation:

5x - 7(-x+2) = 58

Simplify by using the distribution property:

5x - (-7x) - 14 = 58

Simplify by combining like terms:

12x -14 = 58

Add 14 from each side of the equation:

12x = 72

Divide both sides by 12:

X = 72/12

x = 6

Now you have x, replace x in the second equation and solve for y:

y = -x +2

y = -6 +2

y = -4

X = 6, y = -4

732.7 I think

Step-by-step explanation:

You just multiply 28 by 26.17

Answer:

26.17*28=723.76 inches

Why?

There is 28 desks and they are 26.17 inches long. If you line them all up you have 28 desks each 26.17 inches in a line. Which is 26.17*28. Multiple and you get 723.76

Answer:

600

Step-by-step explanation:

Well, the closest number for 17 is 20, and for 27 is 30.

When we multiply those two numbers :

20*30=600

We got 600

To estimate 17 x 27 using compatible numbers, round 17 to 20 and 27 to 25, then multiply to get an estimated product of 500.

Using compatible numbers to estimate the product of 17 x 27 involves finding numbers close to 17 and 27 that are easier to multiply mentally, such as multiples of 10.

A good choice here would be to round 17 up to 20 and 27 down to 25 for the approximation.

By doing so, we simplify the multiplication to 20 x 25.

The estimated product using compatible numbers would be:

20 x 25 = 500

So, an estimated answer to 17 x 27 using compatible numbers would be 500.

This method provides a quick and easy way to estimate the result, which is particularly useful when exact calculations are not necessary, or you need a fast approximation.

Answer: a) (x, y) → (x + 1, y + 3)

              b) (2, -5) → (3, -2)

Step-by-step explanation:

the x-axis goes left and right, so 1 step to the right means you need to add 1 unit to the x-coordinate.

the y-axis goes up and down, so 3 steps up means you need to add 3 units to the y-coordinate.

Rule:

If original x-coordinate is x, then the new coordinate is x + 1 (x → x+1)

If original y-coordinate is y, then the new coordinate is y + 3 (y → y+3)

Final position:

If original x-coordinate is 2, then the new coordinate is 2 + 1 (2 → 3)

If original y-coordinate is -5, then the new coordinate is -5 + 3 (-5 → -2)

Answer:

circle E & circle F

Step-by-step explanation:

We want to see which circles are congruent to circle A, a circle of radius of 6 units.

The correct options are E and F.

Let's see how to solve this:

First, we need to understand what congruent figures are.

We say that two figures are congruent if they have the exact same shape and size.

Then we need to see which other circles also have a radius (distance from the center to the line) is also of 6 units. (or a diameter of 12 units)

The image of the options can be seen at the end of the answer, there, we can see that circle E has a radius of 6 units, so we know that circle E is congruent to circle A.

We also can see that circle F has a diameter (twice the radius) of 12 units, then the radius is:

R = D/2 = 12/2 = 6 units.

Then circle F is also congruent to circle A.

Then the correct options are E and F.
