Answer:
Stephen has 9 trees
Alice has 21 trees
Step-by-step explanation:
At the beginning:
Stephen = x trees
Alice = x + 12 trees
At the end:
Alice = (x + 12) - 4 trees
Stephen = x + 10 trees
Total = 36
Then
Stephen - 9 trees
Alice - 9 + 12 = 21 trees
Answer:
Stephen has 9 trees
Alice has 21 trees
Step-by-step explanation:
Alice has 12 more trees in her garden than Stephen has. After Stephen planted 10 more trees and Alice dug out 4, together they had 36 trees. How many trees did each of them have at the beginning?
Answer:
0.010423315 x 109 = 1.04 x 107 people
Step-by-step explanation:
(19 x 109) = (6.7 x 109) (e100k)
Â
and solve for k
Â
(19 x 109) / (6.7 x 109) Â = Â e100k
Â
Â
2.835820896 = e100k
Â
ln 2.835820896 = ln e100k
Â
ln 2.835820896 = 100k
Â
k = (ln 2.835820896) / 100
Answer:
The answer is option C=150%
Step-by-step explanation:
Original cost of the jacket=$16 in January
Final cost of jacket=$24 in September
What percentage must of the original price is the new?
The new price=the original price×(A percentage)
Where the new price=$24, the original price=$16, and the percentage=(x/100)
24=16×x/100
x=(24×100)/16=150%
The answer is 150%
Answer:
c
Step-by-step explanation:
Percent counts the quantity per 100 (cent=100). The productivity of Gourmet Pretzels increased(in percentage) is given by: Option b. 50%
Suppose the value of which a thing is expressed in percentage is "a'
Suppose the percent that considered thing is of "a" is b%
Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means).
Thus, that thing in number is
For the given case, increment in her productivity is obtained by
Increment = New productivity - previous productivity
Increment amount = 1200 - 800 = 400 pretzels each shift
Let it is p% of the previous productivity.
Then,
Her productivity increased by 50% (compared to previous productivity).
Hence, the productivity of Gourmet Pretzels increased(in percentage) is given by: Option b. 50%

Answer:
Change in productivity will be 50%
So option (b) will be correct option
Step-by-step explanation:
It is given that it takes 8 hour to bake 800 pretzels
And there is a shift of 8 hours
So hourly production =
Now the production is increases to 1200
Now hourly production =
So change in productivity  = %
So option (b) will be correct answer
She can divide the 8 cups by the 1/3 cups
Step-by-step explanation:
The next step will be to divide 8 cups by 1/3 cups
This will be:
=  8÷1/3
=8*3/1-------------dividing by a fraction is the same as multiplying by its reciprocal
= 24
There are 24 Â 1/3cups in 8 cups.

Answer:
Rosa divides the result of by 2
Step-by-step explanation:
We are given that
Rosa puts vegetable mixture in tortilla= cup
She has total vegetable mixture=8 cups
We have to find the what else must Rosa do to find how many tortillas she can fill.
She first finds how many 1/3 cups in 8 cups of vegetable mixture.
Number of 1/3 cups of vegetable mixture=
Number of 1/3 cups of vegetable mixture=
Now, we will find number of tortillas by dividing 24 by 2
She can fill  tortillas of vegetable mixture=
Hence,Rosa divides the result of by 2.
Answer:
Step-by-step explanation:
Goal scored:
Team A: ; which equals 3 players.
Team B: ; which equals 3 players.
So, if 1/6 equals 3 players, what is the total, we can see this as a specific expression:; being the variable the total number of players, solving this equation:
Doing the same process for Team B:
Hence, Team A has 18 players, and Team B has 15 players.
Answer:
The white cell count of 8750 is considered healthy.
Step-by-step explanation:
The question calls for any white cell count below 1500 above 7500 to be considered healthy. So, by adding the number 1500 to 7500 we find that the upper limit for being healthy is 9000 white blood cells per cubic millimeter of blood. This all can be represented mathematically with the following:
If:
Then
White blood cell count 'x' is healthy.
Else if:
or
Then
White blood cell count 'x' is not healthy.
Now let's test the white cell count of 8750.
Does it fall between 7500 and 9000?
This checks out so the answer is yes: White blood cell count '8750' is healthy.
Answer: 4
Step-by-step explanation:
First arrange the given data in ascending order :-
Number of terms = 9
Second quartile =Median=
Now, the first quartile =The median for the lower half of data
= Mean of 2nd term and 3rd term
The third quartile =The median for the upper half of data
= Mean of 7th term and 8th term
Now, Interquartile range =
Hence, the interquartile range of the data =4.

Answer:
A: 21, 34; B: 13
Step-by-step explanation:
Part A:
OK to find this answer you just need to add the 6th and 7th terms together:
Then you add your new 8th term (this term being 21) to your 7th term to get the ninth term:
Part B:
If you subtract the 9th term by the 8th term you'll get the 7th term. This is because to get the 9th term the 7th and 8th terms needed to be added together. So you'd get 13 by subtracting the 8th term from the 9th term because it is the 7th term.
