A certain bacteria culture grows at a rate of 18% everyday. There are currently 420 bacteria. How many bacteria will there be on

spayn [35]

In this question, it is given that

A certain bacteria culture grows at a rate of 18% everyday. There are currently 420 bacteria.

And we have to find number of bacterias on day *.

For that we use the following formula

$N(t) =N_{0} (1 +r)^t$

$N(0)= 420, r = 0.18 , and \ t = 8days$

Substituting these values in the formula, we will get

$N(8)= 420(1+0.18)^8
\\
N(8)=1579$

THerefore on day 8, number of bacterias are 1579.

Answer:

$g = - 3$

Step-by-step explanation:

$- 3 - 2g = - 12 - 5g$

<em>grou</em><em>ping</em><em> like</em><em> </em><em>ter</em><em>ms</em>

<em> $- 2g + 5g = - 12 + 3$ </em>

<em> $3g = - 9$ </em>

<em>divi</em><em>ding</em><em> </em><em>th</em><em>rough</em><em> </em><em>by</em><em> </em><em>3</em>

<em> $\frac{3g}{g} = \frac{ - 9}{3}$ </em>

<em> $g = - 3$ </em>

What is the answer to this question please explain (picture included)

Yakvenalex [24]

Easy peasy
just use PEMDAS and some exonential laws

$(x^{m})(x^{n})=x^{m+n}$
$(x^{m})^{n}=x^{mn}$
$(ab)^{m}=(a^{m})(b^{m})$

also another is $x^{\frac{m}{n}}=\sqrt[n]{x^{m}}$

so

$[3(2a)^{\frac{3}{2}}]^{2}$ =
$(3^{2})((2a)^{\frac{3}{2}}^{2})$ =
$(9)((2a)^{\frac{3}{2}}^{2})$ =
$(9)((2a)^{\frac{6}{2})$ =
$(9)((2a)^{3})$ =
$(9)(8a^{3})$ =
$72a^{3}$

HELP ASAP PLEASE!!!!!

Musya8 [376]

The rule for inscribed angles and their corresponding arcs is that the measure of the angle is one-half that of the arc. Therefore, all we have to do is divide 68/2, which gets us an answer of D. 34.

Hope this helps!
