Solve the multiplication first then the division and the subtract them to get something like this:
$30- \frac{1}{3}
= \frac{89}{3}$
which simplifies to 29.7 (3 significant figure )

Answer:

$\frac{1}{5}$

Step-by-step explanation:

Using the rules of exponents

$a^{m}$ × $a^{n}$ = $a^{(m+n)}$ , $\frac{a^{m} }{a^{n} }$ = $a^{(m-n)}$ , $(a^m)^{n}$ = $a^{mn}$

Simplifying the product of the first 2 terms

$\frac{a^{p^2+pq} }{a^{pq+q^2} }$ × $\frac{a^{q^2+qr} }{a^{qr+r^2} }$

= $a^{p^2-q^2}$ × $a^{q^2-r^2}$

= $a^{p^2-r^2}$

Simplifying the third term

5( $(a^p+r)^{p-r}$

= 5 $a^{(p+r)(p-r)}$ = 5 $a^{(p^2-r^2)}$

Performing the division, that is

$\frac{a^{(p^2-r^2)} }{5a^{(p^2-r^2)} }$ ← cancel $a^{(p^2-r^2)}$ on numerator/ denominator leaves

= $\frac{1}{5}$

Answer:

74.7 km/h

Step-by-step explanation:

The computation of the average speed is shown below:

As we know that

Speed = Distance ÷ Time

where

Distance = 66 km

And, the time is from 14.54 to 15.47 is 53 minutes

So, the speed is

= 66 km ÷ 53 minutes

= 74.71698 kilometers per hour

= 74.7 km/h

⦁ Suppose that the number of bacteria in a dish increases by 50% every four hours. There are 64 bacteria initially. Write a func

Sav [38]

Number of bacteria = 64•(1.5^(t/4))
So after t=100 hours,
64•(1.5^25) = 1,616,075 or 1.616x10^6
