Answer:
110°
Step-by-step explanation:
just add 85+25 and that's equal to 110°
Answer:
x = 20/32
Step-by-step explanation:
you have to distribute first.
1) times 4 by all the nubmers and figures inside the pharanthesese and so you get 32x + 20
2) you have to solve for x and so you move the 20 to the other side and get 32x = 20
3) you then divided both sides by 32 to get x by itself and you get x = 20/32
Data set 1: 14,15,17,18,21
mean: (14+15+17+18+21)/5 = 85/5 = 17
mad
17-14 = 3
17-15 = 2
17-17 = 0
17-18 = 1
17-21 = 4
(3+2+0+1+4)/5 = 10/5 = 2
17/2 = 8.5 is the means-to-mad ratio
Data set2: 15,16,17,20,22
mean = (15+16+17+20+22)/5 = 90/5 = 18
mad
18 - 15 = 3
18 - 16 = 2
18 - 17 = 1
18 - 20 = 2
18 - 22 = 4
(3+2+1+2+4)/5 = 12/5 = 2.4
18/2.4 = 7.5 means to mad ratio
For this case, the area is given by:
A = x * (200-2x)
Rewriting:
A = 200x-2x ^ 2
Deriving the expression we have:
A '= 200-4x
Equaling zero we have:
200-4x = 0
We clear x:
4x = 200
x = 200/4
x = 50 feet
Then, the maximum area is:
A (50) = 50 * (200-2 * 50)
A (50) = 5000 feet ^ 2
Answer:
the maximum possible area that can be enclosed with his 200ft of fencing is:
A (50) = 5000 feet ^ 2
the complete question in the attached figure
Volume of the sand V=(1/3)*h*π*r²
we have that
h=30 mm
r=10 mm
v=(1/3)*30*π*10²=1000≈3140 mm³
the rate is 50 mm³/seg
50 mm³--------------------------------------> 1 seg
3140 mm³-------------------------------- X
x=3140/50=62.8 seg
the answer is 62.8 seg
