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).
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
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.

What is the equation for the line in slope-intercept form?
Can someone help, please
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-interceptWe 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

Harold buys hot dogs and water bottles for a fundraiser. He can buy a pack of 8 hot dogs for $6, and a pack of 6 water bottles for $4. He buys 192 hot dogs and bottles of water together, and spends a total of $136.
How many packs of hot dogs and packs of water bottles does Harold buy?
A. 16 packs of hot dogs and 12 packs of water bottles
B. 12 packs of hot dogs and 16 packs of water bottles
C. 10 packs of hot dogs and 15 packs of water bottles
D. 14 packs of hot dogs and 12 packs of water bottles
Answer:
B
Step-by-step explanation:
hotdogs:
12 packs x 8 = 96
water:
16 packs x 6 = 96
total:
96 + 96 = 192
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-
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.

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.
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

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

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
Which best explains why the slope of the line between points A and D is the same as the slope between points A and B?
Answer: Which best explains why the slope of the line between points A and D is the same as the slope between points A and B? Points A, D, and B are on the hypotenuses of similar triangles. Therefore, AD = AB, so the slope of AD is the same as the slope of AB.
