Answer:
x = 35.4
Step-by-step explanation:
Sum of all interior angles in a triangle = 180°
Therefore:
(x + 2)° + (2x + 2)° + (2x - 1)° = 180°
x + 2 + 2x + 2 + 2x - 1 = 180
Collect like terms
x + 2x + 2x + 2 + 2 - 1 = 180
5x + 3 = 180
Subtract 3 from each side
5x + 3 - 3 = 180 - 3
5x = 177
Divide both sides by 5
5x/5 = 177/5
x = 35.4
Surface area o fthe ball = 4 * 3.14 * radius^2
if diameter = 1.680 then radius = 1/2 * 1.680 = 0.84
so surface area = 4 * 3.14 * 0.84^2 = 8.862
Answer:
The conclusion to be drawn is:
The actual proportion of teenagers who do not smile is only 8%. It is clear that exactly 6 out of 10 teenagers will smile in their driver's license photo.
If we continued to take more samples of 10 teenagers, the center of the distribution would shift to
Step-by-step explanation:
Answer:
24761 mosquitoes
5.4 days
Step-by-step explanation:
Let the equation that shows the population of the mosquitoes after x days,
Where,
P = Initial population,
r = rate of increasing per day,
Here, A = 1000, when x = 0,
A = 1900 when x = 1,
Thus, the required function that represents the population after x days,
If x = 4,
The number of mosquito after 4 days,
If A = 60,000,
Taking log both sides,
Thus, there will 60,000 mosquitoes after 5 days.
Answer:
568 in 2 boxes
Step-by-step explanation:
852 = total of grapes
852 ÷ 3 = 284 per box
To find 2 boxes:
284 + 284= 568
