Answer:
Step-by-step explanation:
y=mx+b where m=slope and b=y intercept
m=(y2-y1)/(x2-x1)=(22-4)/(0+8)=2.25
y=2.25x+b, using point (0,22) we can solve for b
22=2.25(0)+b
b=22
y=2.25x+22 or stating it fractionally
y=9x/4+22
Answer:
125.66
Step-by-step explanation:
11cm squared times pi =380.13
9cm squared times pi =254.47
380.13-254.47=125.66
Answer:
The answer is B. not D.
Step-by-step explanation:
It takes 5 shovels of sand to make 1 shovel of mortar so how many will it take to have 30 shovels of mortar? You can put this in a proportion.
5/1 = x/30
You don't need to worry about the cement since it's asking for sand.
Cross multiply and you get x·1 and 30·5. So this means you need 150 shovels of sand. x=150 when you multiply 30·5.
