Answer:

4√34

Step-by-step explanation:

Let the unknown side be y

y^2 = 20^2 + 12^2

y^2 = 400 + 144

y^2 = 544

Take the square root of both side

y = √544

y = √(16x34)

y = √16 x √34

y = 4√34

Solve this inequality: 3q + 11 + 8q > 99.
IrinaVladis [17]
3q + 11 + 8q > 99

Simplify

11q + 11 > 99

Subtract 11 on both sides

11q + 11 - 11 > 99 - 11
11q > 88

Divide 11 on both sides.

q > 8

Your final answer is C. q > 8<span>.</span>

A scientist running an experiment starts with 100 bacteria cells. These bacteria double their population every 15 hours. Find ho
kati45 [8]

Answer:

it takes 24 hours for the bacteria cells to increase to 300

Step-by-step explanation:

WE use the formula

C= A(b)^{\frac{t}{d}}

Where A is the initial amount of bacteria= 100

bacteria doubles every 15 hours so b=2

d= 15 because d is the time taken to double the number

t is the number of hours

c is the number of bacteria after t hours = 300

Plug in all the values and solve for 't'

300= 100(2)^{\frac{t}{15}}

Divide both sides by 100

3=(2)^{\frac{t}{15}}

Now we take log on both sides

log(3)=log(2)^{\frac{t}{15}}

As per log property we can move the exponent before log

log a^m = m log(a)

log(3)=\frac{t}{15}log(2)

Divide both sides by log(2)

\frac{log(3)}{log(2)} = \frac{t}{15}

Multiply both sides by 15

\frac{log(3)}{log(2)}*15=t

t = 23.77

So its approximately 24 hours
