Answer:

Ari has 14 pennies.

Step-by-step explanation:

                           Number             Value             Total value

Pennies                  p                      $0.01                  0.01p  

Nickels               (22 - p)                $0.05             $(22 - p)0.05  

Total                       22                        -                      $0.54

Since Ari has total value of the coins = $0.54

0.01p + (22 - p)0.05 = 0.54

0.01p - 0.05p + 1.1 = 0.54

-0.04p = -0.56

p = \frac{0.56}{0.04}

p = 14

Therefore, total number of pennies Ari has = 14

A colony of bacteria is grown under ideal conditions in a laboratory so that the population increases exponentially with time. A
Naddik [55]

Answer:

Initial bacterias = 6006000

Altought I believe is safe to assume that the values were 192,000 and 384,000 instead of 192,192,000 and 384,384,000, in that case the initial bacterias is 6000

Step-by-step explanation:

A exponential growth follows this formula:

Bacterias  = C*rⁿ

C the initial amount

r the growth rate

n the number of time intervals

Bacterias (55 hours) = 192,192,000

Bacterias (66 hours) = 384,384,000

Bacterias(55hours)=C*r^{{\frac{55-t}{t}}} \\Bacterias (66hours) = C*r^{\frac{66-t}{t}}}

If you divide both you can get the growth rate:

\frac{Bacterias (66hours)}{Bacterias(55hours)}=\frac{C*r^{\frac{66-t}{t}}}{C*r^{{\frac{55-t}{t}}}} \\\frac{384,384,000}{192,192,000} =r^{\frac{66-t}{t} -\frac{55-t}{t} } \\2 =r^{\frac{11}{t}}

So with that r = 2 and each time interval correspond to 11 years

Then replacing in one you can get the initial amount of C

Bacterias (55hours)=C*2^{\frac{55-11}{11} } 192,192,000 = C*32\\C= 6006000

What is the volume of the pyramid shown?
Vilka [71]

Answer:

The answer to your question is 440 in³, this is my result I can not see the height in the picture I think the number is 40 in

Step-by-step explanation:

Data

length of a side = 6 in

height = 40 in           Is really 40?

Volume of a square pyramid = ?

Process

1.- Calculate the area of the base

Ab = 6 x 6

    = 36 in²

2.- Calculate the volume of the Pyramid

Volume of a square pyramid = 1/3 (36 x 40)

                                                = 1440 / 3

                                                = 480 in³
