Two Petri dishes were on the desktop in Dr. McFarlan's lab.

Dish A had cells with a radius of 3.4 × 10^-13 cm. Dish B had cells that had a radius of 4.6 × 10^-11 cm. What is the sum of the radii of the two types of cells, using scientific notation?
A.
4.634 × 10^-15 cm
B.
46.34 × 10^-14 cm
C.
463.4 × 10^-13 cm
D.
4.634 × 10^-11 cm

the answer is the third / last answer

step-by-step explanation:

p ÷ r = tan(x)

step-by-step explanation:

given that there is a figure below shows a right triangle: a right triangle is shown with hypotenuse equal to q units and the length of the legs equal to p units and r units.

graph is missing so i will create the graph as per given information.

the angle between the legs having lengths p units and q units is y degrees. the angle between the legs having lengths r units and q units is x degrees.

now we need to find about what is p ÷ r equal to.

so we can use trigonometric ratio tan(x)=[altitude]/[base] to find the value of p ÷ r, because p is the altitude and r is the base.

p ÷ r=tan(x)

hence final answer is p ÷ r=tan(x).

answer: 75°

step-by-step explanation:

∠esk is the supplement of ∠edk, so is 100°. ∠esd = 1/2·arc ed, so is 25°.

since ∠esk = ∠esd + ∠dsk

you have 100° = 25° + ∠dsk . .

fill in known values 75° = ∠dsk . . . . .

subtract 25°
