I'm assuming you want the algebraic expression:
x -> The number
(x + 2 + 1/100)/3
Answer:
V = 14 + 5t
14 + 5t ≥ 49
Lucy has to add water at least for 7 minutes.
Step-by-step explanation:
There were 14 liters of water in Lucy's fish tank. She was about to add water at the rate of 5 liters per minute until there were at least 49 liters of water in the tank.
If t represents the number of minutes she adds water and V is the volume of water in liters in the fish tank, then we can write the equation as
V = 14 + 5t ........... (1)
Now, this volume of water in the tank V must be at least 49 liters.
So, 14 + 5t ≥ 49 is the required inequality.
⇒ 5t ≥ 35
⇒ t ≥ 7
So, Lucy has to add water at least for 7 minutes. (Answer)
Answer:
$8.40
Step-by-step explanation:
A store sells ½ pound of beef for $0.70
We find the unit rate
1/2 pound = $0.70
1 pound =
We cross Multiply
1/2 × x = 1× 0.70
x = 0.70 ÷ 1/2
x = 0.70 × 2/1
x = $1.40
The unit rate for 1 pound of beef is $1.40
If you are having a party and need 6 pounds of beef for hamburgers
Hence, the cost for 6 pounds of beef is:
1 pound = $1.40
6 pounds = y
y = 6 × $1.40
y = $8.40
6 pounds of beef for hamburgers would cost $8.40
Answer:
a) N = 2^8 = 256
b)N = 2^8 + 2^7 +2^6 +2^5 +2^4 +2^3 +2^2 +2^1
Step-by-step explanation:
Given;
String of length 8, with two options (0 or 1) each.
a) for the number of bits of strings of length 8.
Each digit of the 8 digit string has 2 options.
For 8 digit, we have
N = 2×2×2.... = 2^8 =256
b) for bit of strings of length 8 or less.
For n string = 2^n
For n < 8
The number of bit strings for length 8 or less are;
N = N8 +N7 + N6 + ... +N1
N = 2^8 + 2^7 +2^6 +2^5 +2^4 +2^3 +2^2 +2^1
Answer is:
D.
Step-by-step explanation:
Use the vertical line test to determine whether or not a graph represents a function. If a vertical line is moved across the graph and, at any time, touches the graph at only one point, then the graph is a function. If the vertical line touches the graph at more than one point, then the graph is not a function.
