you need to know the mass of the jewelry box before you can know the volume but i can help you multiply th 15 and the 10 to get the mass most likely then divided what you have from 15 x 10 by the depth and you have your answer just be sure to round it off!
Whats the expression so you can plug those numbers in.
Answer:its 10 :)
Step-by-step explanation:
The window is 54.12 in tall.
Step-by-step explanation:
- Step 1: The window can be imagined as 2 right triangles. The diagonal represents the hypotenuse of the right triangle = 65 in and base = 36 in. Find the other side, which will give the height of the window.
Using Pythagoras Theorem, Hypotenuse² = Base² + Height²
Height² = 65² - 36² = 4225 - 1296 = 2929
⇒ Height of the window = √2929 = 54.12 in
A bacteria culture starts with 500 bacteria and doubles in size every half hour.1
(a) How many bacteria are there after 3 hours?
We are told “. . . doubles in size every half hour.” Let’s make a table of the time and population:
t 0 0.5 1.0 1.5 2.0 2.5 3.0
bacteria 500 1000 2000 4000 8000 16000 32000
Thus, after three hours, the population of bacteria is 32,000.
(b) How many bacteria are there after t hours?
In t hours, there are 2t doubling periods. (For example, after 4 hours, the population has doubled 8
times.) The initial value is 500, so the population P at time t is given by
P(t) = 500 · 2
2t
