18. The perimeter is simply √3 + √3 + √3 + √3 or 4√3cm, since the perimeter is just all sides added together. You could add the decimal numbers together using a calculator, which I'm not sure if you're supposed to do in your class.
The area is just width times length, so √3 • √3 = 3cm².
19. The perimeter is 2√5 + 2(9 - √5).
This can also be written as 2√5 + 18 - 2√5, which leaves you with a perimeter of 18ft.
The area would be √5 • (9 - √5), which leaves you with (9√5 - 5)ft².
20. The formula for the perimeter (or circumference) of a circle is π times the diameter of the circle. Using the radius of the circle, 1/π, the diameter is 2/π, so
π • 2/π = 2. The circumference of the circle is 2 inches.
The area of the circle is calculated with the equation πr², so
π(1/π)² = π • 1/(π²) = π/(π²) = π. The area is simply π in².
Answer:
1
Step-by-step explanation:
-5 is 6 less than 1 so
-5 < 1
Answer:
in 630 minutes, the population of the bacteria will 64,000
Step-by-step explanation:
current population of the bacteria = 8,000
and this population doubles every 210 minutes
0 (minute) ------------------------ 8,000 bacteria
210 + 0 (210 minutes) -------------------- 2 x 8,000 = 16,000 bacteria
210 + 210 ( 420 minutes) -------------------- 2 x 16,000 = 32,000 bacteria
420 + 210 (630 minutes) -------------------- 2 x 32,000 = 64,000 bacteria
Therefore, in 630 minutes, the population of the bacteria will 64,000
You cant you have to measure the angels and then you write down what you get after measuring.
Answer:
set of related events, movements, or things that follow each other in a particular order.
Step-by-step explanation:
a sequence is an enumerated collection of objects in which repetitions are allowed and order matters. Like a set, it contains members (also called elements, or terms). The number of elements (possibly infinite) is called the length of the sequence.
