Set up a pair of proportional ratios...
a/(2πr)=α/360
a=(πrα)/180, we are given that r=12 and α=36° so
a=432π/180 in
a=12π/5 in
a=2.4π in
a≈7.54 in (to nearest one-hundredth of an inch)
Answer:
v= 7*6/2 *8 (The last one)
Step-by-step explanation:
To find the volume you have to multiply the base and the height which is 7 and 6 and divide it by 2. Then you multiply the 8.
Answer:
11 6/9
Step-by-step explanation:
Daniel works in a market
He has large bags of potatoes that weighs 26 1/4
Daniel is going to sell them in smaller bags 9/4 pounds each
Therefore the number of smaller bags of potatoes in which Daniel would have filled can be calculated as follows
= 26 1/4 ÷ 9/4
= 105/4 ÷ 9/4
= 105/4 × 4/9
= 105/9
= 11 6/9
Answer: Work done by both of them in k hours is
Explanation:
Since we have given that
Number of hours Mr. I does a job = x hours
Number of hours Mr. L does a job = y hours
Work done by Mr. I is given by
Work done by Mr. L is given by
Work done if they do together is given by
Work done if they work together for k hours is given by
Hence, work done by both of them in k hours is
Solution: =====> -7 + {12 - 3[50 - 4(2 + 3) ] } ======> -85
Simplify :
−7 + 12 − 3(50 - 4(2 + 3))
= 5 − 3(50 − 4(2 + 3))
= 5 − 3(50 − (4)(5))
= 5 − 3(50 − 20)
= 5 − (3)(30)
= 5 − 90
= − 85
Answer ========> -85
Hope that helps!!!! : )
