Answer:
5 hours cuz 75 divided by 15 is 5 or 15 x 5 is 75
Answer:
the value of these two numbers are 1/2 and 3/2
Step-by-step explanation:
Given that:
x+y < 2 ---- (1)
y - x > 1 ---- (2)
From equation (2), let y > 1 + x then substitute it into equation (1)
x + 1 + x < 2
2x + 1 < 2
2x < 2 - 1
2x < 1
x < 1/2
From equation (2), replace the value of x to be 1/2
y - 1/2 > 1
y > 1 + 1/2
y > 3/2
Answer:
15 black water bottles
Step-by-step explanation:
let w represent white water bottles, and let b represent black water bottles.
set up a system of equations:
w+b=20
w+2b=35
(the top equation shows that the number of white water bottles he sold and the number of black water bottles he sold equals to 20, since it says that the total number of water bottles is 20. the bottom equation shows that white water bottles cost $1, and black water bottles cost $2, and that the total amount of money he got from selling them is $35).
in the top equation, isolate w:
w+b=20
w=20-b
now we do substitution. in the bottom equation, substitute 20-b for w:
w+2b=35
20-b+2b=35
then, solve:
b+20=35
b=15
this means that he sold 15 black water bottles.
The worth of boat after 11 years is $ 3159.3013
<em><u>Solution:</u></em>
Given that,
Boat costs $16600 and decreased in value by 14% per year
To find: Worth of boat after 11 years
<em><u>The formula for decreasing function is given as:</u></em>
Where,
y is the value after "t" years
t is the number of years
a is the initial value
r is decreasing rate in decimal
<em><u>From given,</u></em>
a = 16600
t = 11
<em><u>Substituting the values we get,</u></em>
Thus the worth of boat after 11 years is $ 3159.3013
