Answer:
This problem is about linear equations. We assume Dale drive X miles, and the total cost is $Y, then we can get:
Plan I: Y=38+0.11X
Plan II: Y=49+0.07X
When both plans cost the same, 38+0.11X=49+0.07X. We will get X = 275miles, and Y=$68.25

Step-by-step explanation:
Most people don’t really learn statistics until they start analyzing data in their own research.
Answer:
A= pi r(r+h2+r2)
Step-by-step explanation:
Multiply the radius by pi, then set that aside for a bit.
Square the height and the radius as well, then add those together. This is how it would look:
3.14 x 4 = 12.56
7 x 7 = 49 ; 4 x 4 = 16 ; 16 + 49 + 4 = 69 ; 69 x 12.56
I think this is the answer. Can't say I'm 100% sure, though.
Hey there!
We can find the answer to this by finding how much is 3/4 of the sugar and subtracting that from the 20 pounds of sugar he started with.
3/4 in decimal form is 0.75, so we can multiply 20 by 0.75 to get 3/4 of 20.
0.75 x 20 = 15
This means 3/4 of the sugar is 15 pounds.
Now we can subtract that from the original 20 pounds he started with.
20 - 15 = 5
He has 5 pounds of sugar left.
Hope this helps!
