Answer: 18900
Step-by-step explanation:
Given the question:
In 2001, the Guinness Book of World Records recognized a breakfast which served 18,941 people as the largest ever cooked. Which number below shows 18,941 rounded to 3 significant digits?
18,941 rounded to 3 significant figures
To round to 3 significant figures, the first 3 numbers are kept intact, then the subsequent number is rounded up to 1 if up to or greater than 5 and added to the third figure. If less than 5, all subsequent numbers are rounded down to 0
Hence,
18,941 = 18900 (because 4 is less than 5, 4 and all subsequent numbers are rounded down to 0).

At a sale this week, a suit is being sold for $306 . This is a 15% discount from the original price.
What is the original price?
Answer:
260.1
Step-by-step explanation:15% of 306=45.9
306-45.9=260.1
Answer:
351.9
Step-by-step explanation:
x/306=15/100. then I cross multiplied. And when I do I get 100x/100=4590/100.
I cross out the 100/100 and I leave with x, then I divide 4590 with 100 and get 45.9. So x=45.9.
Then I added the price it was sold..=306+45.9=351.9

(2y+14.6+3.8)-(34.8m+15.6+2y)
Answer:
5.6
Step-by-step explanation:
You most likely will end up putting it in slope form y=mx+b
(2y+14.6+3.8)-(34.8m+15.6+2y) collect like terms
(2y+18.4)-(34.8m + 15.6 + 2y) = 2.8 + 34.8m
2y-2y= 0
18.4 - 15.6= 2.8
34.8m -0 = 34.8m
2.8 + 34.8m ( I think we should further simplify)
so minus 2.8 on both sides
34.8m = -2.8(divide by 34.8 on both sides)
m = -7/87
Plug in
(2y+14.6+3.8)-(34.8(-7/87)+15.6+2y) collect like terms
(2y+18.4)-(-2.8 + 15.6 + 2y) collect like terms
(18.4)-(12.8)= 5.6
2y-2y = 0
34.8(-7/87)= -2.8
18.4 - 12.8 = 5.6

Step-by-step explanation:
The members of Ms. Wilson’s quiz bowl team earned the scores listed below in the past 6 competitions they attended:
82, 76, 94, 71, 68, 89
Mean = The mean is the average of the numbers
Mode=The number which appears most often in a set of numbers.
Range : Range is the difference between the lowest and highest values.
Variance :A measure of how spread out numbers are
So, By definitions we can say that Variance is the measure best summarizes all of the team’s scores
Sam lives near a lagoon in the Caribbean that is populated by flamingos. Sam decides to figure out approximately how many flamingos live in the area. He catches 45 flamingos, put tags on them, and releases them. Later, he catches 280 flamingos, 30 of which are tagged. To the nearest whole number, what is the best estimate for the flamingo population?
Answer:
about 330
Step-by-step explanation:
280 rounded is 330 and 30 is already rounded so you would add 30 plus 330
Answer:
THE ANSWER IS 330 BUT YOU WOULD ADD 300 PLUS 30

In a certain chemical, the ratio of zinc to copper is 4 to 17 . A jar of the chemical contains 663 of copper. How many grams of zinc does it contain?
Answer:
The jar contains 156 grams of zinc
Step-by-step explanation:
Ratios
Let's call
Z=gr of zinc
C=gr of copper
We know the ratio between them in a certain chemical is:
[tex]\displaystyle \frac{Z}{C}=\frac{4}{17}[/tex]
The jar of the chemical contains C=663 gr of copper. Calculate the grams of zinc by solving the above relation for Z:
Multiplying by C:
[tex]\displaystyle Z=\frac{4}{17}\cdot C[/tex]
Substituting the value of C:
[tex]\displaystyle Z=\frac{4}{17}\cdot 663[/tex]
Z=156 gr
The jar contains 156 grams of zinc

9. A car is traveling in a straight line path at a maximum speed of 7.00 m/s. The
driver of the vehicle applies the brakes bringing the car to a stop after traveling
10.0 m. What is the magnitude of the car's acceleration to the nearest
hundredths place?
Answer:
30mph
Step-by-step explanation:
The magnitude of the car's acceleration is 2.45 m/[tex]\rm sec^2[/tex] and this can be determined by using the equation of kinematics.
Given :
A car is traveling in a straight-line path at a maximum speed of 7.00 m/s.The driver of the vehicle applies the brakes bringing the car to a stop after traveling 10.0 m.According to the kinematics:
[tex]\rm v = u + at[/tex] --- (1)
where v is the final speed, u is the initial speed, a is the acceleration and t is time.
Now, put the known terms in equation (1).
0 = 7 + at
at = -7
[tex]\rm t = -\dfrac{7}{a}[/tex] --- (2)
From the kinematics the displacement is given by the equation:
[tex]\rm S =ut+\dfrac{1}{2}at^2[/tex]
Now, put the values of u, S, and t in the above equation.
[tex]10=7\times \dfrac{-7}{a}+\dfrac{1}{2}\times a \times \dfrac{49}{a^2}[/tex]
Now, simplify the above equation.
[tex]10=-\dfrac{49}{a}+\dfrac{49}{2a}[/tex]
20a = -49
a = -2.45
So, the magnitude of the car's acceleration is 2.45 m/[tex]\rm sec^2[/tex].

A product's demand per period follows a normal distribution with mean of 60 and standard deviation of 10. The lead time is 3 periods. What order-up-to level should be used to achieve at least a 90% in-stock probability?
Answer:
209
Step-by-step explanation:
Since the lead time is 2 periods at the time of order, the stocks should last for 3 periods with the 90% probability.
The z-value of 90$ in stock probability = 1.7
Mean of the demand over is (1 + 1 + 1 ) or (2+1 which is 3)
= 60 x 3 = 180
Now the standard deviation of demand over the three periods = 17.3
Therefore, the order up level would be = 180 + ( 1.7 x 17.3 )
= 209

The water level of a lake rose by 1 2/3 in. during a 3 1/3 week-long wet spell. Simplify the complex
fraction below to find the average rate at which the water level changed every week.
Given that,
The water level of a lake rose by 1 2/3 in. during a 3 1/3 week-long wet spell. We need to find the average rate at which the water level changed every week. It is a problem based on the concept of ratio. So,
[tex]R=\dfrac{1\dfrac{2}{3}}{3\dfrac{1}{3}}\\\\=\dfrac{\dfrac{5}{3}}{\dfrac{10}{3}}\\\\=\dfrac{5}{3}\times \dfrac{3}{10}\\\\=\dfrac{1}{2}[/tex]
So, the average rate at which the water level changed every week is 1/2 inches/week.

Step-by-step explanation:
Susan is buying supplies for a party. Spoons only come in bags of 12 and forks only come in bags of 22.
What is the least number of spoons and the least number of forks she can buy so that she has the same number of each?.
Answer:
The least number of spoons = 11 spoons
The least number of forks = 6 forks
Step-by-step explanation:
We are told in the question:
Spoons only come in bags of 12
Forks only come in bags of 22.
This is an LCM question, hence, we find the Multiples of 12 and 22
The first common multiple is found and this is the lowest common multiple.
Multiples of 12:
12, 24, 36, 48, 60, 72, 84, 96, 108, 120, 132, 144, 156
Multiples of 22:
22, 44, 66, 88, 110, 132, 154, 176
Therefore,
LCM(12, 22) = 132
The least number of supplies she can have is 132.
So therefore,
The least number of spoons = 132 ÷ 12 bags of spoons = 11 spoons
The least number of forks = 132 ÷ 22 bags of forks = 6 spoons.
