Answer:
- At 1pm, the number of bacteria in the dish is 1,000,000
- At 12pm, the number of bacteria in the dish is 500,000
Step-by-step explanation:
Given the information on the table
We are to follow the pattern to determine how many million bacteria were in the dish at 1 p.m. and 12 p.m.
Now:
It therefore means that the bacteria population doubles every hour. Following this pattern and reducing the exponents by 1 backwards, we have:
Therefore:
- At 1pm, the number of bacteria in the dish is 1,000,000
- At 12pm, the number of bacteria is 0.5 million=0.5 X 1,000,000=500,000
Answer:
hours
17.75 hours
Step-by-step explanation:
<u>LCM of 2, 4, and 8</u>
2 = 2 × 1
4 = 2 × 2
8 = 2 × 2 × 2
LCM = 2 × 2 × 2 × 1
LCM = 8
<u>GCF of 254 and 8</u>
254 = 2 × 127
8 = 2 × 2 × 2
GCF = 2
<u>LCM of 2 and 4</u>
2 = 2 × 1
4 = 2 × 2
LCM = 2 × 2 × 1
LCM = 4
Answer:
Step-by-step explanation:
-7y = -4x + 9
7y = 4x - 9
y = 4/7x - 9/7
perp. -7/4
y - 3 = -7/4(x - 4)
y - 3 = -7/4x + 7
y = -7/4x + 10
Rewrite the first equation as y = -x+10
plug in this equation into y in the second equation
solve for x
x = 34
plug x=34 into the first equation
solve for y
y = -24
THE ANSWER IS: (34,-24)
