Answer:
302.4
Step-by-step explanation:
252% × 120 =
(252 ÷ 100) × 120 =
(252 × 120) ÷ 100 =
30,240 ÷ 100 =
302.4
15 and 21. From 1 to 3 is plus 2 and from 3 to 6 is plus 3 and from 6 to 10 is plus 4 and so on
Answer:
48 ways
Step-by-step explanation:
There are 52 cards in a deck and four nines. This means that nines account for 4/52 of the deck. The opposite of 4/52 (idr the math word for that) is 48/52. Therefore, there are 48 other ways that a card other than nine can be obtained.
Answer:
n=-7/2 I hate asking for things but can i have brainliest im trying to rank up.
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
n/7−12=5n+5
1/7n+−12=5n+5
1/7n−12=5n+5
Step 2: Subtract 5n from both sides.
1/7n−12−5n=5n+5−5n
-34/7n−12=5
Step 3: Add 12 to both sides.
-34/7n−12+12=5+12
-34/7n=17
Step 4: Multiply both sides by 7/(-34).
(7/-34)*(-34/7n)=(7/34)*(17)
Answer:
a = 30
b = 6/7
Step-by-step explanation:
The number of yeast cells after t hours is modeled by the following equation:
In which a is the initial number of cells.
At time t = 0 the population is 30 cells
This means that 
So
And increasing at a rate of 18 cells/hour.
This means that f'(0) = 18.
We use this to find b.
So
Then, it's derivative is:
We have that:
f'(0) = 18
So
Then
