Answer: At 10:20 a.m., there will be 16 cells in the bottle.

At 10:30 a.m. there will be 64 cells in the bottle .

Step-by-step explanation:

Since we have given that

At 10:05 a.m. number of microscopic bacteria cells in the bottle = 2

At 10:15 a.m. number of microscopic bacteria cells in the bottle = 8

It means in every 5 times the number of microscopic bacteria cells in the bacteria gets twice itself.

So, by following the same pattern we can get that,

At 10:20 a.m. number of microscopic bacteria cells in the bottle is given by

$8\times 2=16$

Hence, At 10:20 a.m., there will be 16 cells in the bottle.

Similarly,

At 10:25 a.m. number of microscopic bacteria cells in the bottle is given by

$16\times 2=32$

At 10:30 a.m. number of microscopic bacteria cells in the bottle will be

$32\times 2=64$

Hence, At 10:30 a.m. there will be 64 cells in the bottle .

Solve –4(6x + 3) = –12(x + 10). A. x = 2 B. x = 9 C. x = 5 D. x = –5

sergey [27]

–4(6x + 3) = -12(x + 10)
 -24x - 12 = -12x - 120
12x = 108
x = 9

answer
B. x = 9

Which is the least common denominator of 5/6 3/8

Tems11 [23]

To find the least common denominator, or lcd, you have to find the least common multiple, or lcm. To do that you find the multiples of each number until they equal each other. I set up a chart like this,

6 -

8 -

and then I start listing multiples so,

6 - 6, 12, 18, 24,

8 - 8, 16, 24,

I stop after I find a number they are both equal to. So to get to that number I would multiply 8 by 3, and 6 by 4. This gives me 24 as the lcd. If you need the lcd to add the fractions together, then whatever you did to the bottom do to the top. So 5/6 would become 20/24 and 3/8 would become 9/24.

Find the slope of the line that passes through (10, 3) and (7, 11).

Vadim26 [7]

Answer:

Slope of the line is $-\frac{8}{3}$ .

Step-by-step explanation:

Given points are:

(10, 3) and (7, 11)

Here,

x1 = 10 and y1 = 3

x2 = 7 and y2 = 11

Slope of a line is given by

$m = \frac{y_2-y_1}{x_2-x_1}\\\\m = \frac{11-3}{7-10}\\\\m = \frac{8}{-3}$

Therefore,

Slope of the line is $-\frac{8}{3}$ .
