34 as a percent is 3400%

In order to get this number you move the decimal to places to the right:
34.0 ---> 3400.0 =
3400%

What is the approximate volume of the sphere

NISA [10]

Answer:

523.33 mm³

Step-by-step explanation:

The general formula for the volume of a sphere is:

V = $\frac{4}{3}\pi r^{3}$

The radius for the given sphere is 5mm, so plugging that value into the equation and using 3.14 for π:

V = $\frac{4}{3}(3.14)(5^{3})$

V ≈ 523.33 mm³

Model Exponential Growth Question :A sample of bacteria is growing at a continuously compounding rate. The sample triples in 10

Iteru [2.4K]

Answer:

The number of bacteria $B$ after $d$ days is given by

$B = B_0 (3)^{\frac{1}{10} d}$

where $B_0$ is the initial number of bacteria.

Step-by-step explanation:

The number of bacteria $B$ in the sample triples every 10 days, this means after the first 10th day, the number of bacteria is

$B = B_0 *3,$

where $B_0$ is the initial number of bacteria in the sample.

After the 2nd 10th days, the number of bacteria is

$B = (B_0 *3)*3$

after the 3rd day,

$B =( B_0 *3*3)*3$

and so on.

Thus, the formula we get for the number of bacteria after the <em>n</em>th 10-days is

$B = B_0 (3)^n$

where $n$ is is the <em>n</em>th 10-days.

Since, $n$ is 10 days, we have

$d =10n$

$n =\dfrac{1}{10}$

Substituting that into $B = B_0 (3)^n$ , we get:

$\boxed{ B = B_0 (3)^{\frac{1}{10} d}}$

Please help me on this

BabaBlast [244]

Answer:

C. 4 weeks

Step-by-step explanation:

We have the formula

$s = 16 \sqrt{7t} + 62$

We are looking for the value of t (number of weeks) when s = 150.

So, we isolate t (well, almost isolate, because it would be hard to read)

$(\frac{s - 62}{16} )^{2} = 7t$

If we replace s by 150 we get:

$7t = (\frac{150 - 62}{16} )^{2} = (\frac{88}{16} )^{2} = (5.5 )^{2} = 30.25$

We have 7t = 30.25. If we divide both sides by 7 we get the number of weeks: 4.32... so rounding it down to 4.
