Answer:24
Step-by-step explanation:
40% 60 is just 0.4⋅60=24
The vertical distance between Dean and Jeff is 13 ft below the surface
Explanation:
Jeff dove 39 ft below the surface and then ascends 18 ft
-39 - 18 = 21
Jeff is 21 ft below the surface
------------------
Dean is 34 ft below the surface
-34 - (-21) = -13 ft
-----------------
So, Dean and Jeff are 13 feet away from each other (vertical distance).
Answer:
The value of x = 0.41
Step-by-step explanation:
∵ 
Let 
∴ 
∴ 6y² - 5y = 6
∴ 6y² - 5y - 6 = 0 ⇒ factorize
∴ (3y + 2)(2y - 3) = 0
∴ 3y + 2 = 0 ⇒ 3y = -2 ⇒ y = -2/3
∴ 2y - 3 = 0 ⇒ 2y = 3 ⇒ y = 3/2
∵ 
∴ 
⇒ refused
(
never gives -ve values)
∵ 
⇒ insert <em>ln</em> in both sides
∵ 
⇒ <em>ln</em>(e) <em>= 1</em>
∴ 
∴ x = ln(3/2) = 0.41
Answer:
30 gallons of 6% milk, and 45 gallons of 1% milk.
x=quarts of 6% butterfat
First, write an equation.
0.06x+0.01(75-x)=0.03*75
Multiply both sides by 100.
0.06x*100+0.01*100(75-x)=100*0.03*75
Simplify
6x+75-x=3*75
6x+75-x=225
Solve
5x=225-75=150
5x=150
x=30
75-30=45
So, we need 30 gallons of 6% milk, and 45 gallons of 1% milk.
Step-by-step explanation:
-6,-7, and -8, this is more of a guess and check question
