Good luck:)
Answer:1. (3*4)+2= she'd have to bring 14$
2. (26-9)+7=24 she'd have to grade 24 worksheets
3.
(16-8)*7=56 he made 56$
4. (20-8)÷2=16 games
5. (6+2)*3=24 cans
6. (33+9)÷6=7 points
7. (13+43)+23=79 towels
Step-by-step explanation:
So,
We need to convert qt. to c.
4 c. = 1 qt.
8 * 4 = 32 cups
Thomas will make 32 1-cup servings of soup.
Answer: V =
Step-by-step explanation: A solid formed by revolving the region about the x-axis can be considered to have a thin vertical strip with thickness Δx and height y = f(x). The strip creates a circular disk with volume:
V = Δx
Using the <u>Disc</u> <u>Method</u>, it is possible to calculate all the volume of these strips, giving the volume of the revolved solid:
V =
Then, for the region generated by y = - x + 4:
V =
V =
V =
V =
V =
The volume of the revolved region is V =
Cos(pi) = -1
You should have this memorized along with other values such as
sin(0) = 0
cos(0) = 1
sin(pi/2) = 1
cos(pi/2) = 0
sin(pi) = 0
cos(pi) = -1
sin(3pi/2) = -1
cos(3pi/2) = 0
and remember that tan = sin/cos
