Normally, compasses are circles
you didn't give us a height so we only need to compute the area of the face of the compass


area of circle=pir²
2r=d so



area=12.56
12.56=pir³
aprox pi=3.141592
divide both sides by pi or 3.141592
3.99=r³
sqrt both sides
about 2
2=r

2r=d
2(2)=d
4=d

diameter is 4cm

According to the National Oceanic and Atmospheric Administration, the blue whale is the largest animal on Earth. Blue whales wei
never [62]

Answer: The blue whale's weight is 150 times heavier than the narwhal's weight.

Step-by-step explanation:

Given: Weight of Blue whale = 3\times10^5\text{ pounds}

Weight of Narwhal = 2\times10^3\text{ pounds}

Number of times blue whale's weight  is heavier than the narwhal's weight = =\dfrac{\text{Weight of Blue whale}}{\text{Weight of Narwhal }}

=\dfrac{3\times10^5}{2\times10^3}\\\\=1.5\times10^{5-3}\ \ \ [\dfrac{a^m}{a^n}=a^{m-n}]\\\\=1.5\times10^2\\\\=1.5\times100=150

Hence, the blue whale's weight is 150 times heavier than the narwhal's weight.

Joe's Ice Cream Shop has 7/8 of a gallon of vanilla ice cream left. They use 1/12 of a gallon of ice cream to make one milkshake
Vadim26 [7]

Answer:

Ten and a Half milkshakes can be prepared from the available amount of ice cream.

Step-by-step explanation:

The total vanilla ice cream = 7/8 gallons

Ice cream used for 1 milkshake = 1/12 gallon

Now, total number of milkshakes possible = \frac{\textrm{Total availibility of ice cream}}{\textrm{Ice cream used for each milkshake}}

= \frac{\frac{7}{8} }{\frac{1}{12} }  = \frac{7}{8}  \times \frac{12}{1}  = 10.5

Hence ten and a half milkshakes can be prepared from the available amount of ice cream.

Fruit Company A recently released a new applesauce. By the end of its first year, profits on this product amounted to $37,100. T
Anastasy [175]

Answer: 11 year

P(1) = 37,100

P(4) = 58,400

The linear equation (for x ≥ 1)

P(x) = 37,100 + a(x-1)

For x = 4

58,400 = 37,100 + a(4-1)

58,400 - 37,100 = 3a

21300 = 3a

a = 7100

So, the linear equation:

P(x) = 37100 + 7100*(x-1)

P(x) = 37100 + 7100x - 7,100

P(x) = 7100x + 30000

To find when the profit should reach 108100, we can substitute P(x) by 108100.

108100 = 7100x + 30000

108100 - 30000 = 7100x

78100 = 7100x

x = 78100/7100

x = 11
