Assume that an average cell has a diameter of
emmasim [6.3K]

Given that the volume of a cell is 50 cubic micrometers. It says to find the number of cells present in 1 cubic centimeter.

So we need to first convert the units of volume of a cell, then we can find the total number of cells in 1 cubic centimeter.

We know 1 meter = 100 centimeters = 1000000 micrometers

So 1 centimeter = 10000 micrometers

Taking Cubic powers on both sides :-

1 cubic centimeters = 10¹² cubic micrometers

1 cubic micrometers = 10⁻¹² cubic centimeters

50 cubic micrometers = 50 × 10⁻¹² = 5 × 10⁻¹¹ cubic centimeters

So volume of one cell = 5 × 10⁻¹¹ cubic centimeters

Number of cells = \frac{Total\;\; volume}{Volume\;\; of\;\; one\;\; cell}  = \frac{1\;cm^{3}}{5 * 10^{-11}\;cm^{3}} = \frac{10^{11}}{5} = 2 × 10¹⁰ cells.

So, total number of cells = 2 × 10¹⁰ cells.

The answer is: he can eat 48 hotdogs in 12 minutes. How? Well, first, to find the amount of hotdogs he can eat in 1 min. you have to divide 32 by 8, and obviously you get 4. Now you multiply 4 by 12 and you get your answer, which is 48. Good luck with your homework!

Help pls plsssssssss
Salsk061 [2.6K]

Answer:

area = 0.5 \times height \times width \\  = 0.5 \times (x + 2) \times (x +2  - 7) = 4 \\ 4  \div 0.5 = (x + 2)(x - 5) = 8 \\  {x}^{2}  - 3x - 10 = 8 \\  {x}^{2}  - 3x - 18 = 0 \\ (x - 6)(x  + 3) = 0 \\ x =  - 3 \\ x = 6
