Answer:
$0.21/lb
Step-by-step explanation:
We are to find the price per pound:
Number of tons given = 2 tons;
1US ton contains 2000lb
2 tons will have mass of 2 x 2000 = 4000lb
price = $840
So';
Price per pound =
= $0.21/lb
<span>M divides JK into two parts with lengths in a ratio of 1:3
so JM:MK is either 3:1 or 1:3
before solving for M, need to find mid-pt of JK, point L
L is at (-4+8)/2 and (11-1)/2 so L is at (2,5)
mid-pt of JL is at (-4+2)/2 and (11+5)/2 so it is at (-1,8)
and mid-pt of LK is at (8+2)/2 and (-1+5)/2 so it is at (5,2)
note that these pts are the fourths. They </span><span>divide the segment into fourths, so the three-quarter segment is indeed thrice as long as the quarter segment. They are the ans for pt M.
M is (-1,8) or (5,2)

Answer:
x = 7
Step-by-step explanation:
10 / 4 = x + 8 / x - 1
[cross multiply]
10 (x - 1) = 4 (x + 8)
[distribute the factors]
10x - 10 = 4x + 32
+ 10 + 10
[add 10 to both sides to cancel out -10]
10x = 4x + 42
-4x -4x
[subtract both sides by 4x to cancel out 4x]
6x = 42
÷6 ÷6
[divide both sides by 6 to simplify 6x to x]
x = 7
________
x = 7 → 10 / 4 = x + 8 / x - 1 →
(7) + 8 / (7) - 1 → 15 / 6 →
15 ÷ 3 / 6 ÷ 3 → 5 / 2 →
5 × 2 / 2 × 2 → 10 / 4 = 10 / 4
Answer:
-160
Step-by-step explanation:
-3(-5+4)cubed+(-10+9)squared(-2)
15+(-12)cubed+(-10+9)squared(-2)
15+(-12)cubed+(-10)+9squared(-2)
3cubed+(-10)+9squared(-2)
9+(-10)+9squared(-2)
9+(-10)+81(-2)
-1+81(-2)
80(-2)
-160
A≈ 2π× r× h + 2π r² = 2π· 1.7 ×3 + 2×π× 1.7² = 50.20
A= Area π= (pie) 3.14 r= radius h= height
So therefore the answer is 50.20265 , simplified 50.20
