2 angles that are complementary. One angle is 4 degrees less than three times the other angle. Find the measures of the angles.

1 answer:

6 0

Complementary angles add to 90o

the other angle = x
the first angle = 3x - 4

x + 3x - 4 = 90
4x - 4 = 90
4x = 94
x = 94/4
x = 23.5

the first angle = 3*23.5 - 4 = 66.5

Escherichia coli cells are about 2.65 μm long and 0.480 μm in diameter. Calculate the volume of an E. coli cell, assuming the ce

zmey [24]

Answer:

4.7953 x 10⁻¹⁹ m³

Step-by-step explanation:

Length of the Escherichia coli cell (L) = 2.65 x 10⁻⁶ m

Diameter of the Escherichia coli cell (D) = 0.480 x 10⁻⁶ m

The volume of cylinder in given by:

$V= \frac{\pi D^2}{4}*L \\V= \frac{\pi (0.480*10^{-6})^2}{4}*2.65*10^{-6}\\V= 4.7953*10^{-19} m^3$

The volume of an E. coli cell is 4.7953 x 10⁻¹⁹ m³.
