Answer: 8
Step-by-step explanation:
we know the area of a circle is
A=π r²
50.24= 3.14* r²
50.24/3.14=r^2
16=r^2
r=sqrt 16=4
diameter is 2r=2*4=8
Answer:
20 2/3 feet
Step-by-step explanation:
7 3/4 * 2 2/3 = 20 2/3
Convert into improper fraction..
= 31/4 * 8/3
...
Solve equation...
= 20 2/3
The area of the garden is 20 2/3.

Answer:
233.3 repeating mg
Step-by-step explanation:
Your teacher was really kind to give you the equation.
9x=2100
divide both sides by 9
we get x= 233.3 repeating mg
Answer: y = 54(1.06)^t
Step-by-step explanation:
It is estimated that the population of bacteria will increase by 6% each hour. This is an exponential growth. The formula for determining exponential growth is expressed as
y = b(1 + r)^ t
Where
y represents the population after t years.
t represents the number of years.
b represents the initial population.
r represents rate of growth.
From the information given,
b = 54
r = 6% = 6/100 = 0.06
Therefore, the formula for the population of bacteria is
y = 54(1 + 0.06)^t
y = 54(1.06)^t
Answer:
black = 0.28
white = 0.22
pink = 0.24
blue = 0.26
Step-by-step explanation:
Jason and his friend spun the spinner 100 times total. So for each time landed on a color, it can be counted as one percentage (for example, black had a 28% frequency). To transfer percentages to decimal form, simply bring the decimal point over by two spaces (28 becomes 0.28, something like 4 would become 0.04). Hope this helps! Feel free to ask any questions!
