ANSWER: y = -8x - (-10)
The answer is in slope intercept form which it y=mx+b.
“m” is the slope which is -8 in this problem. “b” is the y-intercept which is -10 in this problem. You just plug them in to get the answer.

A student earned the scores in the data set in one course. {78, 64, 74, 92, 67} What is the mean of the scores?

Answers

Answer: The mean is 75

Step-by-step explanation:

- You add the scores in the data:

78+64+74+92+67 = 375

- Then divide by the number of scores in the data:

there are 5 scores in the data,

1) 78

2) 64

3) 74

4) 92

5) 67

- So:

375/5 = 75 <--- mean

Answer: 75

To calculate mean or average from a data set, add all the data points together and then divide by the number of points you added together.
In this case,
78+64+74+92+67= 375/5= 75

A swimming pool is being drained at a rate of 50 gallons per hour. How many milliliters per second is this? Round to the nearest tenth.

Answers

Answer: 3154.16 milliliters / second

Step-by-step explanation:

1 gallon = 3.785 liters

1 liter = 1000 milliliters.

So multiply to convert: 1 gallon x 3.785 liters/gallon x 1000 milliters/liter = 3785 milliters ; 50 gallons = 50*3785 = 189250 milliliters

1 hr = 60 seconds 50 gallons per hour = 189250 mililiters/60 seconds =3154.16 milliliters/second

result : 50 gallons per hour = 3154.16 milliliters / second

Answers

Answer: y = 10x - 10

This means 10 goes into each box, without any minus symbols.

==========================================

Reason:

Recall that slope-intercept form is y = mx+b

m = slopeb = y-intercept

We simply replace m with 10 since this the slope. We replace b with -10 because it's the y-intercept.

So,

y = mx+b

y = 10x+(-10)

y = 10x - 10

---------------

Extra info:

If you wanted to graph this, then I would start at the y intercept location of (0,-10). Then move up 10 units and to the right 1 unit to arrive at (1,0). Draw a straight line through these two points.

To find the x intercept, replace y with 0 and solve for x. The equation 0 = 10x-10 solves to x = 1.

Answer: y=10x-10

Step-by-step explanation:

10 being the point the slope crosses the y-axis

-10 being the degree of the slope

A groundskeeper needs grass seed to cover a circular field, 290 feet in diameter. One pound of grass seed covers about 400 square feet of field.

How many pounds of grass seed should the groundskeeper buy to cover the circular field?

-EXPLAIN YOUR RESONING-

Answers

Answer:165.13 pounds of grass seed.

Step-by-step explanation: to find the area of a circle you must do the equation pi r^2, so in this case that is pi*145, because radius is half the diameter, and that gets you approximately 66051.99 ft^2. when you divide 400 by this number, you get approximately 165.13 pounds of seed.

An object has a mass of 17 grams.

What is its weight in ounces?

Use 1 ounce=28.35 gram to write the conversion facto

Answers

0.6 oz would be objects weight in ounces

Step-by-step explanation:

In order to determine the weight of an object in ounces, we need to convert its mass from grams to ounces using the conversion factor of 1 ounce = 28.35 grams. Since the mass of the object is 17 grams, we can use the conversion factor to calculate its weight in ounces as follows:

17 grams * (1 ounce / 28.35 grams) = 0.6 ounces

Therefore, the weight of the object in ounces is 0.6 ounces. The conversion factor used in this calculation is 1 ounce = 28.35 grams.

Answer:

16.449 = 16.4

9.84 = 9.8

by estimating = 26.2

Answer:

16.5+9.8=26.3

Step-by-step explanation:

The equation is 16.449+9.84. We need to add these together after we round them to the nearest tenth. Well with decimals it goes ones, tenths, hundreths. So The second number past the decimal on the right side, is the one that we are rounding. If the number is greater than 5 then we move the number to the next tenth value.If its less than f5 we do the complete opposite.

16.449 is going to be rounded to be 16.5.

9.84 is going to be rounded to be 9.8

Now that our numbers are rounded we can add them.

16.5+9.8=26.3

I hope this helps!!!

Any additional help with rounding to the nearest tenth you could, if you want, use the website nearesttenth.com (Just to help you, I don't work with that website and not trying to advertise it like that).

What is the perimeter of a rectangle with a length of Eight and one-sixth feet and a width of Six and two-thirds feet?

Fourteen and three-ninths feet
Sixteen and two-sixths feet
Twenty-nine and four-sixths feet
Forty-eight and three-eighteenths feet

Answers

Answer:

Fourteen and three ninthn feet

Step-by-step explanation:

Just add them together and you get the answer.

Answer: Twenty-Nine and Four-Sixths feet

Step-by-step explanation:

Perimeter is the sum of all sides.

So we just add 8 1/6 + 8 1/6 + 6 2/3 + 6 2/3

but before we can add them up we need to make our fractions have the same denominators

so we multiply the 2/3 by 2 to give us 4/6 then we can add the fractions together

1/6 + 1/6 + 4/6 + 4/6 = 10/6 or 1 4/6

then add 8 + 8 + 6 + 6 + 1 4/6 = 29 4/6 feet
