Bacteria doubles every 10 minutes. If you start with 2 bacteria in a petri dish, how many bacteria will there be after 40 minutes?
Answer: I think the answer is 32 bacteria after 40 minutes.
Step-by-step explanation:
I think that's right because the bacteria that have previously multiplied will also be multiplying. 2 becomes 4, 4 becomes 8, etc. until you've reached 40 minutes. (I'm honestly unsure, but I think this is right?) I hope this helped!
The medians of ADEF are DK, EL, and FJ. They meet at a single point M.
(In other words, M is the centroid of ADEF.)
Suppose ML = 9, MJ=8, and DK = 24.
Find the following lengths.
Note that the figure is not drawn to scale.
Answer:
FJ = 24
DM = 16
EM = 18
Step-by-step explanation:
I remember that the centroid is 2/3 of the distance from each vertex to the midpoint of the opposite side. Therefore the median is split into two parts where one side is always twice as long as the other. So given that segment ML is 8, the other part of the segment (DM) must be 16 as 16 is 2/3 of 24 and 8 is 1/3 of 24 and 1/3 + 2/3 = 1.
Therefore, since MJ is 8, FM must be twice as long so it is 16. Add them up to get FJ, and 8 + 16 is 24.
Finally for EM, since the longer part of the median is twice the length of the smaller part EM must be 18 since 9 × 2 = 18, and 2/3 of 18 is 27, 9 + 18 = 27.
Consider the line 4x+2y=-7.
What is the slope of a line perpendicular to this line?
What is the slope of a line parallel to this line?
Answer:
To find slop from the given equation,
Slope (m) =
[tex] \frac{ - \: cofficients \: of \: x }{cofficient \: of \: y} [/tex]
So, slope of this equation is - 2
For perpendicular case,
M1 . M2 = - 1
Thus, m2 = 2 ( for this equation)
Similarly,
For parallel case,
M1 = m2
Thus, m2 = - 2 ( for this equation)
Keep asking sir/maam» Which expression shows 35 + 15 written as a product of two factors?
Answer:
[tex]35 + 15 = 5 * 10[/tex]
The factors are 5 and 10
Step-by-step explanation:
Given
[tex]35 + 15[/tex]
Required
Express as a product of two factors
[tex]35 + 15[/tex]
Start by factorizing the expression:
[tex]5(7 + 3)[/tex]
Add the expression in the bracket
[tex]5(10)[/tex]
Replace bracket with *
[tex]5 * 10[/tex]
Hence:
[tex]35 + 15 = 5 * 10[/tex]
The expression which shows 35 + 15 written as a product of two factors is 5(7 + 3).
What is meant by expression?An expression, often known as a mathematical expression, is a finite collection of symbols that are well-formed in accordance with context-dependent principles.
A number, a variable, or a mix of numbers, variables, and operation symbols make up an expression. Two expressions joined by an equal sign form an equation.
Let the expression be 35 + 15
Express as a product of two factors
35 + 15
Factorizing the expression we get
5(7 + 3)
simplifying the above expression, we get
5 (10)
Hence:
35 + 15 = 5 × 10
Therefore, the correct answer is option b) 5(7 + 3).
The complete question is:
Which expression shows 35 + 15 written as a product of two factors?
a) 5(6 + 3)
b) 5(7 + 3)

~~~PicklePoppers~~~Peyton is collecting data on the lunch habits of students at Hyattsville Middle School. In one class, 14 students bring lunch from home, and 20 buy a school lunch. Hyattsville Middle School has 1700 students. From the data collected, how many students would Peyton predict would buy a school lunch? *
Answer:
Answer: Around 1000 students would buy a school lunch.
Step-by-step explanation:
We know that in one class, 14 students bring lunch from home, and 20 buy lunch in the school. This will be our sample.
In total we have 20 + 14 = 34 students, this will be our 100%.
The percentage of students that bring lunch from home can be estimated as the quotient between the number of students that bring lunch from home and the total number of students, times 100%.
p1 = (14/34)*100% = 41.18%
And the percentage of students that buy lunch at school can be computed in the same way:
p2= (20/34)*100% = 58.82%
Then, out of the 1700 students in middle school, we can estimate that around 58.82% of them will buy lunch in the school.
Then the exact number will be:
N = (58.82%/100%)*1700 = 1000
Around 1000 students would buy a school lunch.
How do I multiply 24 times 18
Answer:
432
Step-by-step explanation:
The multiplication of number 24 times 18 gives the result 432.
To multiply 24 by 18, you can follow the standard multiplication algorithm:
24
x 18
-----
192 (24 multiplied by 8)
240 (24 multiplied by 10)
-----
432 (The final product)
Therefore, 24 multiplied by 18 equals 432.

Step-by-step explanation:
Answer:
Brand A is $14
Brand B is $12.5
Brand B is offering the better value. I know this because when you get the unit rate for Brand A it is $14. When you get the unit rate for Brand B you get $12.5. So You pay less money for Brand B then Brand A.
Step-by-step explanation:
For brand A you need to first divide 70 by 5 which equals to 14
Then you divide 105 by 12 which equals 12.5

Daniel is looking at two different credit card offers. Credit Card A will give him an APR of 22.45%. Credit Card B will offer will be 1.25% each month. Which the better deal?
Answer:
Credit card B is a better deal
Step-by-step explanation:
in order to compare both credit cards, we must either convert the APR into a monthly rate or the monthly rate to APR.
convert credit card A's APR to monthly rate:
= 22.45% / 12 ≈ 1.87%, which is higher than 1.25%, so credit card B is better
OR
convert credit card B's monthly rate to APR:
= 1.25% x 12 = 15%, which is lower than 22.45%, so credit card B is better

Diane earns $14,500 a year. She pays 11% of her gross income for federal, state, and local taxes. She is taxed at the FICA rate of 7.65%. She has 3.5% of her income withheld for personal deductions. She is paid biweekly. What is her net pay for each pay period? Round to nearest cent.
Answer:
$434.16346
Step-by-step explanation:
Given that :
Gross earning= $14500
Federal, state and local taxes = 11%
0.11 * $14500 = $1595
FICA tax rate = 7.65%
0.0765 * 14500 = $1109.25
Personal deduction :
3.5% * 14500
0.035 * 14500 = $507.50
Total deduction :
$(1595 + 1109.25 + 507.50)
= $3211.75
Net earning : $(14500 - 3211.75) = 11288.25
Since she is paid bi weekly:
Number of biweeks in a year = 52 /2 = 26
Number of payments per annum = 26
Hence,
Net pay per period :
11288.25 / 26
= $434.16346

The sales tax rate in New Mexico is 8% You buy an Anime coloring book that is $18. What is the final price of the Anime coloring book? Justify how you determined the final price.
Answer: $ 19.44
Step-by-step explanation:
Give : Original price of coloring book = $18
Sales tax = 8% =0.08 [we divide number by 100 to remove %]
Now , the final price of the Anime coloring book = Original price + (Original price) x (Sales tax)
=$ ( 18+18 x 0.08)
= $ (18)(1+0.08)
= $ (18)(1.08)
= $ 19.44
Hence, the final price of the Anime coloring book = $ 19.44

if I have 24 coins and 7 pouches how many coins can go in each pouch
Answer:
If you have have 24 coins and 7 pouches, you can put 3.43 coins in each pouch.
Step-by-step explanation:
To solve this you want to divide the 24 coins into 7 pouches.
x = coins
y = pouches
z = how many coins can go in each pouch:
[tex]x/y = z[/tex]
Substitute:
24/7 = z
3.42857142857 = z
round to the nearest hundredth:
3.43 = z
If you have have 24 coins and 7 pouches, you can put 3.43 coins in each pouch.
To figure out how many coins go into each pouch, divide the number of coins by the number of pouches.
Coins per pouch = 24/7 = approx. 3.43
Sandy sold 22 tickets, which was at least 6 more than twice the number of tickets that Teresa sold. This can be represented by this inequality, where t represents the number of tickets Teresa sold.
Which could be a number of tickets that Teresa sold?
17
11
7
14
Answer:
7
Step-by-step explanation:
Let 'x' represent the number of tickets that Teresa sold, and x is integer and x>=0 (you can not sell negative number of tickets)
6 + 2x < 22
x < 8
The range of possible number of tickets that Teresa sold is {0, 1, 2, 3, 4, 5, 6, 7}.
what is the parallel slope of 9x - 5y = 4
Answer:
-9x+5y=-4
Step-by-step explanation:
Answer:
m= 9/5
Step-by-step explanation:
Parallel lines have the same slope.
So if you can find the slope of the given line, you have the slope you want.
Change the line into the form
y=mx + c
The value of m
will be the slope of the line.
9x −4 = 5y ← to make the y term positive
y=9/5x − 4/5
m=9/5
