Answer:
On the sixth day (10 - 4), the worm was 2.5mm long.
Step-by-step explanation:
Giving the following information:
Future Value= 40mm
Present Value= 2.5mm
Number of periods (n)= ?
Growth rate= 100% per day
First, we need to calculate the number of days it will take to grow from 2.5mm (PV) to 40mm (FV):
n= ln(FV/PV) / ln(1+i)
n= ln (40 / 2.5) / ln (2)
n= 4
It will take 4 days.
On the sixth day (10 - 4), the worm was 2.5mm long.

A fish tank in the shape of a rectangular prism holds 30 cubic feet of water .the tank has a length of 5 feet and width of 3 feet . What is the length in depth,in feet ,of the tank ? A-2
B-6
C-10
D-15
Answer:
A - 2 feet
Step-by-step explanation:
We know that the tank is a rectangular prism which means the volume is equal to length*width*depth
since the tank can hold 30 cubic feet of water, we can divide 30 by the given dimensions of the length and width to find the depth
30/5 = 6
6/3 = 2
therefore, the depth of the tank has to be 2 feet (A)
Length x Width x Depth
From the question:
Volume of the rectangular prism = 30 cubic feet
Length of the rectangular prism = 5 feet
Width of the rectangular prism = 3 feet
Depth of the rectangular prism = ?
The formula to find the Depth of the rectangular prism is :Depth = Volume / (Length x Width)
Hence,
Depth = 30 cubic feet / 5 feet x 3 feet
Depth = 30/ 15
Depth = 2 feet
The correct option is option A

Darcie wants to crochet a minimum of 3 blankets to donate to a homeless shelter. Darcie crochets at a rate of 1/15 blanket per day. She has 60 days until when she wants to donate the blankets, but she also wants to skip crocheting some days so she can volunteer in other ways.
Write an inequality to determine the number of days, s, Darcie can skip crocheting and still meet her goal.
Answer:
Since Darcie wants to crochet a minimum of 3 blankets and she crochets at a rate of 1/5 blanket per day, we can determine how many days she will need to crochet a minimum of 3 blankets following the next steps:
- Finding the number of days needed to crochet one (1) blanket:
\begin{gathered}1=\frac{1}{5}Crochet(Day)\\Crochet(Day)=5*1=5\end{gathered}
1=
5
1
Crochet(Day)
Crochet(Day)=5∗1=5
So, she can crochet 1 blanket every 5 days.
- Finding the number of days needed to crochet three (3) blankets:
If she needs 5 days to crochet 1 blanket, to crochet 3 blankets she will need 15 days because:
\begin{gathered}DaysNeeded=\frac{NumberOfBlankets}{Rate}\\\\DaysNeeded=\frac{3}{\frac{1}{5}}=3*5=15\end{gathered}
DaysNeeded=
Rate
NumberOfBlankets
DaysNeeded=
5
1
3
=3∗5=15
- Writing the inequality
If she has 60 days to crochet a minimum of 3 blankets but she can complete it in 15 days, she can skip crocheting 45 days because:
AvailableDays=60-RequiredDaysAvailableDays=60−RequiredDays
AvailableDays=60-15=45DaysAvailableDays=60−15=45Days
So, the inequality will be:
s\leq 45s≤45
The inequality means that she can skip crocheting a maximum of 45 days since she needs 15 days to crochet a minimum of 3 blankets.
Have a nice day!

−3 ( 7x − 5 ) = 87 + 3x
A. −17/4
B. -3
C. 4
D. 17/3
Answer:
C . 4
Step-by-step explanation:
step 1 : -3 multiply with inside of the ( 7x-5 )
= -21x + 15
step 2 : then it will be 21x + 15 = 87 + 3x
step 3 : switch between the odds into like this
21x - 3x = 87 - 15
step 4 : subtract it all
18x = 72
step 5 : bring 18 to the other side
x = 72/18
step 6 : to find the ans of x is just calculate them
x = 72 ÷ 18
= 4
Or you can do like these ⬇️
-3 ( 7x - 15 ) = 87 + 3x
21x + 15 = 87 + 3x
21x - 3x = 87 - 15
18x = 72
x = 72/18 or 72÷18
x = 4

A square pyramid has a base length of 4 inches. The height of each triangular face is 12 inches. What is the surface area of the pyramid?
Answer:
The surface area of the given pyramid is 112 [tex]inches^{2}[/tex].
Step-by-step explanation:
Base length of the pyramid = 4 inches
Area of the base = [tex]length^{2}[/tex]
= [tex]4^{2}[/tex]
= 16
Area of its base = 16 [tex]inches^{2}[/tex]
Area of one of its triangular surface = [tex]\frac{1}{2}[/tex] x base x height
= [tex]\frac{1}{2}[/tex] x 4 x 12
= 2 x 12
= 24 [tex]inches^{2}[/tex]
Area of all its four triangular surfaces = 4 x 24
= 96 [tex]inches^{2}[/tex]
surface area of the pyramid = sum of areas of all its surfaces
= 16 + 96
= 112 [tex]inches^{2}[/tex]
The surface area of the given pyramid is 112 [tex]inches^{2}[/tex].

A company has offices in two different countries. The 125 employees at location A have a mean commute time of 40 minutes and a standard deviation of 15 minutes. The 250 employees at location B have a mean and standard deviation of 35 and 10 minutes, respectively.
Every month, the company takes separate random samples of 20 employees from each location for a survey. Each time, they look at the difference in the mean commute time sampled from each location
Consider the formula: ...
Why is it not appropriate to use this formula for the standard deviation of ...
Choose
A. The samples are not independent of each other.
B. We cannot assume independence for the employees sampled from location A.
C. We cannot assume independence for the employees sampled from location B.
Answer:
B
Step-by-step explanation:
We cannot assume independence for the employees sampled from location A.
It is not appropriate to use this formula for the standard deviation of
A. The samples are not independent of each other.
What is the difference between the sample and the population?The entire group about whom you want to make conclusions is referred to as a population.
The particular group from which you will gather data is known as a sample. The sample size is always smaller than the population as a whole.
We cannot rely on the workers' sampled employees' independence.
Assuming independence based on the 10% condition requires at least 200 employees in the population with a sample size of 20, however, location A only has 125 employees.

Lisa works at a music store. Last week she sold 6 more than 3 times the number of CDs that she sold this
week. Lisa sold a total of 110 CDs over the two weeks. Find the number of CDs she sold last week and the
number of CDs she sold this week.
Answer:
This week sales = 26
Last week sales = 84
Step-by-step explanation:
Let this week sales = x
Sales last week = 6 + 3x
Sales last week + this week = 110
x + (6 + 3x) = 110
x + 6 + 3x = 110
6 + 4x = 110
4x = 110 - 6
4x = 104
x = 26
This week sales = 26
Last week sales = 6 + 3(26) = 84

Maria who is 6 feet tall stand 20 feet away from the base of a tree she looks up at the top of the tree at 43° angle of elevation what is the approximate height of the tree rounded to the nearest 10th but
Answer:
24.7 feet
Step-by-step explanation:
Maria who is 6 feet tall stands 20 feet away from the base of a tree she looks up at the top of the tree at a 43° angle of elevation.
what is the approximate height of the tree rounded to the nearest 10th?
We solve the above question using the Trigonometric function of Tangent
tan θ = Opposite/Adjacent
θ = Angle of elevation
Adjacent = Distance from the base of the tree = 20 feet
Opposite => Height of the tree = x
θ = 43°
tan 43 = x/ 20 feet
x = tan 43 × 20 feet
x = 18.650301723 feet
Approximately = 18.7 feet
We are told in the question that Maria is 6 feet tall
Therefore, the height of the tree = Maria's height + Height
= 6 feet + 18.7 feet
= 24.7 feet

Answer:
Infinitely many solutions
Step-by-step explanation:
=> -16x - 20y = 16 => - 4(4x + 5y) = 12
=> 4x + 5y = 12/(-4) => 4x + 5y = -3 .. (1)
=> 8x + 10y = - 6 => 2(4x + 5y) = - 6
=> 4x + 5y = -6/2 => 4x + 5y = - 3 ...(2)
Note that both the equations come out be same on simplification. It means, we are given with only 1 equation that is 4x + 5y = -3, and since there is nothing more about this, equation would give different values of y for infinitely many random values of x.
Thus,
