Answer:
The volume of water in the vase is
Step-by-step explanation:
A cylinder vase has a height, h, of 10 inches and its diameter of 3 inches. This means that its radius, r, is:
r = 3 / 2 = 1.5 inches
To find the volume of the water in the vase if the water raises to 9/10 of the way to the top, we first have to find the volume of the vase when it is filled with water and then, find 9/10 of that volume.
The volume of a cylinder is given as:
The volume of the vase will be:
Hence, the volume of the water in the vase when it is 9/10 filled is:
Approximating to the nearest cubic inch, the volume of water in the vase is
Answer:
172.5 cm
Step-by-step explanation:
The scale of the model is 1 : 200, therefore the length of 1 m in the model represent the actual length of 200 m
200 m actual length = 1 m model length
1 m actual length = 1 ÷ 200 = 0.005 m model length
1 m actual length = 0.005 m model length
345 m actual length = 345 x 0.005 m = 1.725m model length
The answer wants it in cm, so we convert the m to cm.
1.725m = 172.5 cm
Answer:
5.12$
Step-by-step explanation:
I know this because when your dealing with 20% think of it like 1/5.
Know 1/5 of 25.60 is 5.12 how I can calculate this is by timesing 5.12 by 5.
Here is what is would look like.
5.12 x 1=5.12$
5.12 x 2=10.24$
5.12 x 3=15.36$
5.12 x 4=20.48$
5.12 x 5=25.60$
And there's your answer(the last one by the way:))
If you want another example based upon 1/5 and 20% then say they were
30 cows and 30 horses 1/5 of them or 20% of them are sitting how many are sitting.
And since it is 1/5 what times 5 would=60 ?
It would be 12 so 20% of 60 is 12, do you understand what I am saying.
Hope this helps have a great day:)
Hey!
------------------------------------------------
They already give us the slope, so we can solve the y-intercept.
We can use (3, -2).
y = 8x + b
-2 = 8(3) + b
-2 = 24 + b
-2 - 24 = 24 + b - 24
-26 = b

Hence, the answer is

Hope This Helped! Good Luck!
Answer:
39 (possibly 40 if you were told to round UP)
Step-by-step explanation:
$20.00-$10.50 = 9.50.
Now, divide -
9.5/0.24 = 39.58333333
