Scientists are examining two different strains of a particular bacteria. The length of one strain of the bacteria measures 0.000000368
mm, while the length of the second strain measures 0.000000064 mm. How much larger is the first strain than the second?
OA. 3.04 x 10-7 mm
OB. 4.32 x 10-7 mm
OC. 4.32 x 10-15 mm
OD. 3.04 x 108 mm
Scientists are examining two different strains of a particular bacteria. The length of one strain of the bacteria measures 0.000000368
mm, while the length of the second strain measures 0.000000064 mm. How much larger is the first strain than the second?
We can figure this out using scientific notation.
[tex]0.000000368 - 0.000000064[/tex]
[tex]= 3.04e-7[/tex]
Put 3.04e-7 in standard notation.
[tex]0.00000304[/tex]
Put 0.00000304 back into scientific notation, instead with a multiply sign.
Move the dot back, making the number in between 1-10.
In this case, we would move it back 7 times.
[tex]3.04[/tex] · [tex]10x^{-7}[/tex]

Luis is going to rent a kayak.
*It costs $18 per hour plus a flat fee of $50 for the insurance.
*Luis can spend $160, at most, to rent the kayak.
What is the maximum number of hours Luis can rent the kayak?
Answer:
6 hours
Step-by-step explanation:
so to do this your gonna
50 + 18 = 68$
then you just add 18 till you reach as close as you can get to 160$
68$+18$=86+18=104+18=122+18=140+18=158$
then you count the 18's
there is 6 18's witch means that Luis is can kayak for a max of 6 hours
The maximum number of hours Luis can rent the kayak gven the amount he can spend is 6 hours.
What is the maximum number of hours Luis can rent the kayak?The equation that represents the total amount of money he can spend is:
$160 = $50 + $18h
Where h represents the number of hours
In order to determine the value of h, take the following steps:
Combine similar terms
$160 - $50 = 18h
Add similar terms
$110 = 18h
Divide both sides by 18
h = 6 hours

Find the value of x.
Answer:
x = 30°
Step-by-step explanation:
84° + 66° + x = 180°
150° + x = 180°
x = 180° - 150°
x = 30°
Answer:
The value of x is 30°
Step-by-step explanation:
The sum of angles of a triangle is equal to 180°
so, x°+66°+84° = 180°
=> x° + 150° = 180°
=> x° = 180°-150°
=> x = 30°
The diagram shows a regular hexagon and a regular pentagon.
Calculate the size of the angle marked x.
You must show all your working.
Since a regular polygon has equal interior angles, then the measure of the angle marked x is: 132°.
What is a Regular Polygon?A regular polygon is any n-sided polygon that has equal interior angles and equal sides.
Thus:
Each angle of a regular hexagon = 120°Each angle of a regular pentagon = 108°Therefore:
x = 360 - 120 - 108
x = 132°
Thus, since a regular polygon has equal interior angles, then the measure of the angle marked x is: 132°.

Which logarithmic equation is equivalent to 25 = 32?.
The logarithmic function is the inverse of the exponential function. The logarithmic function that is equivalent to 2⁵ = 32 is log₂32=5.
What is the Logarithm function?
A log function is a way to find how much a number must be raised in order to get the desired number.
[tex]\rm a^c=b[/tex] can be written as [tex]\rm log_ab=c[/tex].
where a is the base to which the power is to be raised,
b is the desired number that we want when power is to be raised,
c is the power that must be raised to a to get b.
Given to us
2⁵ = 32
As we know that we can convert a number powered to another number therefore exponential function into a log function, thus,
[tex]\rm 2^5=32\\\\log_25=5[/tex]
Hence, The logarithmic function is the inverse of the exponential function. The logarithmic function that is equivalent to 2⁵ = 32 is log₂32=5.

an ice cream factory makes 270 quarts of ice cream in 10 hours. how many quarts could be made in 12 hours? what was that rate per day?
Answer: The factory would make 324 quarts of ice cream every 12 hours.
They make 27 quarts of ice cream per hour, so if they made ice cream for 24 hours, they would be making 648 quarts every day.
Step-by-step explanation:
You would find how may quarts they make an hour by dividing 270 by 10 hours, which brings you out to 27 quarts an hour.

Use the data 10,12,11,10,7,6,7 to Find the mean of the data A.7 B.8 C.9 D.10 E.9.5
Answer:
The answer is C.9
Step-by-step explanation:
in order to fine the mean using number data you need to add all the number then divide by that much numbers. So for example 10+12+11+10+7+6+7 would equal 63. So since you have 7 numbers of data, you need to divide 7 and 63 (7÷63). 7÷63 equals 9. So therefore the answer is C.9.

A point on AD is chosen randomly. Identify the probability that the point is not on AB or CD.
The probability that a point is not on AB is the probability that a point is on BC
The probability that a point is not on AB or CD is 5/14
How to determine the probability?From the figure, we have the following parameters:
AD = 28
AB = 12
BC = 10
CD = 6
if a point is not on AB or CD, then the point would be on BC
This means that we calculate the probability that a point is on BC
So, we have:
P(BC) = BC/AD
This gives
P(BC) = 10/28
Simplify
P(BC) = 5/14
Hence, the probability that a point is not on AB or CD is 5/14

How to calculate compound interest's amount?If the initial amount (also called as principal amount) is P, and the interest rate is R% per unit time, and it is left for T unit of time for that compound interest, then the interest amount earned is given by:
[tex]CI = P(1 +\dfrac{R}{100})^T - P[/tex]
The final amount becomes:
[tex]A = CI + P\\A = P(1 +\dfrac{R}{100})^T[/tex]
How to calculate simple interest amount?If the initial amount (also called as principal amount) is P, and the interest rate is R% annually, and it is left for T years for that simple interest, then the interest amount earned is given by:
[tex]I = \dfrac{P \times R \times T}{100}[/tex]
For the considered case, we're given that:
Initial amount in both accounts deposited = $24,000 = PType of interest: Compound interest in first account and simple interest in second accountUnit of time: AnnuallyRate of interest = 2.4% annually = RTotal unit of time for which amount is to be calculated: 5 years = T
In first account, the final amount at the end of 5 years is evaluated as:
[tex]A = 24000(1 + \dfrac{2.4}{100})^4 = 24000(1.024)^4 \approx 27021.59\: \rm (in \: dollars)[/tex]
In second account, the final amount at the end of 5 years is evaluated as:
[tex]A = 24000 + \dfrac{24000 \times 2.4 \times 5}{100} = 24000 + 2880 = 26880 \text{\: (in dollars)}[/tex]
Total amount after 5 years in these accounts = [tex]27021.59 + 26880 = 53901.59[/tex] (in dollars)
Thus, the sum of the balances of these accounts at the end of 5 years is given by: Option B: $53,901.59 (approx)
