Rasberry Crazy Ants, a species found in wall sockets, cellphones, and television sets are
marishachu [46]

The average time taken to travel to Toronto by  the swarm of Rasberry Crazy Ants  is 12,947 Years

<h3>What is the calculation for the above Solution?</h3>

To arrive at the solution above, we need to look at the information given and the information assumed.

Step 1 - Information given:

  • The swarm are currently at Austin, Texas
  • The swarm move at an average speed of 1.8feet/day

Step 2 - Information assumed:

The swarm are travelling to the location of the student which is assumed to be Toronto.

Hence,

Time taken for the swam to get to Toronto (TTS) =

Distance between Austin, Texas and Toronto (DBTT) / Average distance covered per day by the Rasberry Ants. (ADC)

Estimated distance between Austin Texas and Toronto = 2592.6 Kilometers

Time travelled per day by the ants (In Km) = 0.00054864

Thus,

TTS  = DBTT/ADC

= 2592.6 /0.00054864

≈ 4,725,503.06 days or

≈ 12,947 Years

<h3>Do I need to be worried about these ants infesting your cellphone or television? Do you need to worry for your children? For your grandchildren?</h3>

The answer to both questions is NO.

The average life expectancy in Toronto (as at 2022) is 80 years. Assuming I was born today, it is expected that the time between now and when my last grand child will die is about:

80 x 3 = 240 years.

Given that the ants have to travel 12,947  to get to Toronto, the possibility of my grand children seeing them is zero.

Besides, even if they by chance got to Toronto and infested my grandchildren's residence, they would have nothing to worry about because Rasberry Crazy Ants are 100% harmless.

Find the following rates. Round your answer to the nearest hundredth. a. ? % of 75 = 5 b. ? % of 28 = 140 c. ? % of 100 = 40 d.
Sati [7]

Answer:

a) 6.67% b) 500% c) 40% d) 7.5%

Step-by-step explanation:

a. ? % of 75 = 5

<em>Let ? be y.</em>

<em>Of means multiply so we will replace it with a multiplication sign.</em>

<em>y% x 75 = 5</em>

<em>y% = 5/75</em>

<em>y% = 1/15 x 100</em>

y = 6.67 %

b) ?% of 28 = 140

<em>Let ? be y.</em>

<em>Of means multiply so we will replace it with a multiplication sign.</em>

<em>y% x 28 = 140</em>

<em>y% = 140/28</em>

<em>y% = 5</em>

<em>y = 5 x 100</em>

y = 500%

c) ?% of 100 = 40

<em>Let ? be y.</em>

<em>Of means multiply so we will replace it with a multiplication sign.</em>

<em>y% x 100 = 40</em>

<em>y% = 40/100</em>

<em>y% = 2/5</em>

<em>y = 2/5 x 100</em>

y = 40%

d) ?% of 200 = 15

<em>Let ? be y.</em>

<em>Of means multiply so we will replace it with a multiplication sign.</em>

<em>y% x 200 = 15</em>

<em>y% = 15/200</em>

<em>y% = 3/40</em>

<em>y = 3/40 x 100</em>

y = 7.5 %

FromTheMoon [43]

Answer:

85

Step-by-step explanation:

Order of operations rules (PEMDAS) govern here.  Anything inside parentheses must be done first, followed by exponentiation, mult. and div., and add. and subtr. last.

Add 2+5 first:    5 + 2*{(7)*5 + 5}

Perform the work shown inside the brackets {  and  }:  5 + 2*{40}

Perform the indicated mult.:  5 + 80

Finally, add:  85
