Answer:

Area of trapezoid:

12 + 6<-- your two bases of the trapezoid = 18

18 x 4 = 72, 72 divided by 2 = 36

now we multiply by 2 since there are 2 trapezoids:

36 x 2 = 72

Area of rectangle in front:

6 x 3 = 18

Area of the 2 rectangles on the sides:

5 x 3 = 15

(multiply by 2 since there are two rectangles on both sides)

15 x 2 = 30

Area of rectangle on the back:

12 x 3 = 36

Now lets add up all the areas:

72 + 18 + 30 + 36 = 156 in2 is your answer.

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.

Please help and explain

bagirrra123 [75]

Answer:

See below

Step-by-step explanation:

The three angles inside of the triangle sum to 180

11x + 4 + 3x + 78 = 180

14x +82 =180

x = 7

then B = 11x + 4 = 11(7) + 4 = 81 degrees

C = 3x = 21 degrees

Lets check the first point (0,6)

3*0+4=4 no good

0+6 =6 good

0^2+6 =6 good

6 * (7/6) ^0 =6 good

Lets check the second point (1,7)

3*1+4= we don't care since it didn't work for (0,6)

1+6 =7

1^2+6 =7

6 * (7/6) ^1 =7

Lets check the third point (2,10)

3x+4= we still don't care

2+6 = 8 no good

2^2+6 =10 good

6 * (7/6) ^2 =6 * 49/36 =49/6 no good

f(x) = x^2 +6

The height of a distance marker is 8 2/13 feet. 4/5 of the pole is painted white and rest is painted blue. How much of the pole

Mashcka [7]

1) Convert the mixed number 8 and 2/13 into a fraction:

8 and 2/13 = 8 + 2/13 = (8*13 + 2) / 13 = 106 / 13

2) Calculate 4/5 of 106 / 13

(4 / 5) * ( 106 / 13) = (4*106) / (5*13) = 424 / 65

That is (390 + 34) / 65 = 390/65 + 34/65 = 6 + 34/65 is painted white

3) Calculate the rest

(1/5) * (106 / 13) = 106 / 65 = 1 + 41/65 is painted blue
