Each cow makes 0.20 gallons day
5 x 0.20 = 1 gallon a day for 5 cows
3 x 0.20 = 0.6 gallons a day for 3 cows
0.6 x 5 days = 3 gallons of milk
Answer. 5 Days
Answer:
a)x=-10, b)x=7
Step-by-step explanation:
a)2x+6= x-4
x=-6-4= 10
b) 20x-18x= +8+6
2x/2=14/2= 7=x
Answer: 12
<u>Step-by-step explanation:</u>
Total = Cake + Ice Cream - Both
125 = 80 + 57 - Both
125 = 137 - Both
-12 = -Both
12 = Both
Answer:
t = 1.47 s
Step-by-step explanation:
y(x,t) = 0.6 sin (8 x – 24 t )
compare it with
y = A sin (k x - ω t)
now, A = 0.6
k = 8
ω = 24 rad/s
we know ω = 2πf
we know that
time taken
t = distance/time
= 4.4 / 3
t = 1.47 s
Answer:
55 degrees
Step-by-step explanation:
A complementary angle equals 90 degrees so you know that the two angles together must equal that. The easiest way to set up these problems are to turn it into an algebraic equation. You know that angle a is 20 more than angle b, or angle a is (x+20) and angle b is (x). Your equation would read: x+x+20=90. Simply solve this equation then plug in the answer to whichever angle you need. 2x+20=90, 2x=70, x=35. Angle A is 20 degrees longer making it equal 55.
