Answer:
C
Step-by-step explanation:
The river discharges 4 x 10^6 cubic feet of water into the Pacific Ocean each second.
There are 86,400 seconds in one day.
Amount of water discharges each day-
=4x10^6x86400
=345600000000
=3.456 x 10 ^11
Answer: C
Step-by-step explanation:
1) First multiply 4 * 10^6 = 4,000,000
Then multiply 4,000,000 by 86,400 = 3.456 * 10^11

Kenji walks 44 feet in 10 seconds. At this rate, how many miles does Kenji walk in an hour? show your work. (1 mile = 5,280 feet)
Answers
Answer:
Kenji walks 3 miles in an hour.
Step-by-step explanation:
1 hour = 3600 seconds
3600/10 = 360
So there are 360 increments of 10 in an hour. Multiply 44 by 360 to find the amount of feet in an hour:
(44)(360) = 15840
Now we have to divide 15,840 by the amount of feet in a mile (5,280):
15840/5280 = 3
So Kenji walks 3 miles in an hour.
Kenji walks 3 miles in one hour.
We know that,
1 hours = 60 minutes = 3600 seconds
Since, Kenji walks 44 feet in 10 seconds
Kenji walks in 1 second,[tex]=\frac{44}{10}=\frac{22}{5}feet[/tex]
Kenji walks in 3600 seconds , [tex]=\frac{22}{5}*3600=15840feet[/tex]
Given that, 1 mile = 5,280 feet
So that, [tex]15840feet=\frac{15840}{5280}=3miles[/tex]
Thus, Kenji walks 3 miles in one hour.

How long would three 4 foot long pieces of rope be if they were laid end to end?
Answers
EXPLANATION: If we are measuring in feet than that would mean that all we would have to do is multiply how long one rope is to the quantity of how many ropes there are. In this problem there are 3 ropes that each measure 4 feet long which means that we will have to multiply 3 by 4 to get the answer of 12.

Find the solution (in explicit form) for the following initial value problem: y 0 = xy3 (1 + x 2 ) − 1 2 y(0) = 1.
Answers
Complete Question
The complete question is shown on the first uploaded image
Answer:
The solution is [tex]y^2 = \frac{1}{ 3 - 2 (1 + x^2 ) ^{\frac{1}{2} }}[/tex]
Step-by-step explanation:
From the question we are told that
The function is [tex]\left \{ {{y' = xy^3 (1 + x^2)^{-\frac{1}{2} }} \atop {y(0) = 1}} \right.[/tex]
Generally the above equation can be represented as
[tex]\frac{dy}{dx} = xy^3 (1+ x^2)^{- \frac{1}{2} }[/tex]
[tex]=> \frac{dy}{y^3} = \frac{x}{ (1 + x^2)^{\frac{1}{2} }} dx[/tex]
[tex]\int\limits { \frac{dy }{y^3} } \, = \int\limits {\frac{x}{(1 + x^2) ^{\frac{1}{2} }} } \, dx[/tex]
=> [tex]- \frac{1}{2y^2} = (1 + x^2)^{\frac{1}{2} }+ C[/tex]
From the question we are told that at y(0) = 1
[tex]- \frac{ 1}{2 * (1) } = (1 + (0)^2)^{\frac{1}{2} } + C[/tex]
[tex]C = - \frac{3}{2}[/tex]
So
[tex]- \frac{1}{2y^2} = (1 + x^2)^{- \frac{1}{2}} - \frac{3}{2}[/tex]
[tex]\frac{1}{y^2} = 3-2(1 + x^2)^{\frac{1}{2} }[/tex]
[tex]y^2 = \frac{1}{ 3 - 2 (1 + x^2 ) ^{\frac{1}{2} }}[/tex]

A wheel with a radius of 7 inches is rotating at 4 revolutions per second. What is the linear speed v, in feet per second
Answers
The linear speed of the wheel is v=175.84 inches inches per second.
The radius of the wheel (r) is 7 inches.
We know the circumference of a circle is given by: [tex]\pi\times2r[/tex]
Therefore the circumference of the wheel is [tex]\pi\times2\times 7[/tex] inches
= [tex]14\pi[/tex] inches
The wheel revolves at 4 revolutions per second.
Hence the wheel will go forward [tex]4\times14\pi[/tex] inches in one second
That is, [tex]56\pi[/tex] inches in one second.
Use the value [tex]\pi = 3.14[/tex]
[tex]56\times 3.14[/tex] inches
175.84 inches
Hence, the linear speed of the wheel is v=175.84 inches inches per second.

A test consists of 20questions. Multiple choice questions earn 4points for a correct answer, and free response questions earn 8points for a correct answer. If the test is out of 100points, how many of each type of question are on the test?
Answers
Answer:
15 multiple choice questions
5 free response questions
Step-by-step explanation:
This is basically a systems of equations word problem.
To solve this, we need to create two equations that represent this scenario. Let's suppose [tex]m[/tex] represents the amount of multiple choice questions and [tex]f[/tex] represents the amount of free-choice questions.
We can create the following equations:
[tex]4m + 8f = 100[/tex]
[tex]m+f=20[/tex]
To solve for m and f, we can use elimination.
Let's multiply the equation [tex]m+f=20[/tex] by -4.
[tex]-4m - 4f = -80[/tex]
Great! Now let's add this equation to our first one, [tex]4m + 8f = 100[/tex].
[tex]4m + 8f = 100[/tex]
[tex]-4m - 4f = -80[/tex]
___________________
[tex]0m + 4f = 20[/tex]
[tex]4f=20[/tex]
Dividing both sides by 4 get us [tex]f=5[/tex].
So there are 5 free choice questions. To find m, we can substitute inside the equation [tex]m+f=20[/tex]
[tex]m+5=20\\\\m=20-5\\\\m=15[/tex]
So there are 15 multiple choice questions.

this is the digit that tells you whether to round up or down
Answers
When you want to round up or down numbers focus on only two digits,which is the digit in place that you are rounding to and the digit to it's immediate right which tells you whether to round up or down.When the number you are rounding is between 0-4, you round down to the next lowest number. When the number is 5-9,you round the number up to the next highest number.
For example: If you have 25 and you want to round it up then it will be rounded up to 3 because 5 can be rounded up to the next number which is 2 to make it 3.But when you have 23,then you can't round it up which means you will have to round it down to 20 since the 3 behind the 2 can't round up.

Elizabeth is selling jam at a farmers market, and she earns $5.00 for each jar of jam that she sells. Her goal for the weekend is to earn at least $450.00, and she has already made $95.00 from jam sales as well as $24.00 from leading a demonstration. What is the minimum number of jars Elizabeth must sell at this point to reach her goal?
Answers
Answer:
66 jars of jam
Step-by-step explanation:
Elizabeth is selling jam at a farmers market.
She earns $5 for each jar of Jan that she sells
Her goal is to earn $450 during the weekend.
Elizabeth has already made $95 from the sale of her jams and $24 from leading a demonstration
Therefore the total amount that has been made is
= $95 + $24
= $119
Since her target is $450 and she has already made $119 then the amount remaining to complete the target can be calculated as follows
= $450 - $119
= $331
The minimum number of jars that Elizabeth must sell to realize her goal can be calculated as follows
= 331/5
= 66
Hence Elizabeth must sell 66 jars of jam to reach her goal.

(c) If the 36 chips are all chosen from the top layer of the box of 2000 chips, is this a random sample? why or why not?
Answers
Answer:
a
The population is 2000
b
The sample is 36
c
No this is not a random sample
Step-by-step explanation:
From this question we are told that
A computer outlet store receives a shipment of 2000 computer chips
The number of unites chosen by the owner is n= 36
Generally the population for this statistical test is N = 2000
This is because the 2000 is the entire pool from which a statistical sample is drawn
Generally 36 is the sample because this is the number that will be statistically tested and its result will be generalized for every other element of the population
Now if the 36 chips are all selected from the top then the sample is not a random sample because in a sample each element of the sample have an equal likelihood of been selected from the population but in the case of the question each element are selected base it accessibility

When two straight lines or rays intersect at a shared endpoint, an angle is generated. The measure of ∠DCF is 132°.
What is an angle?When two straight lines or rays intersect at a shared endpoint, an angle is generated. An angle's vertex is the common point of contact. Angle is derived from the Latin word angulus, which means "corner."
The diagram for the given explanation can be made as shown below.
Given the measure of ∠DCE and ∠ECF as 78° and 54°, respectively. Therefore, we can write,
∠DCF = ∠DCE + ∠ECF
= 78° + 54°
= 132°

Complete question :
Suppose there are n independent trials of an experiment with k > 3 mutually exclusive outcomes, where Pi represents the probability of observing the ith outcome. What would be the formula of an expected count in this situation?
Answer: Ei = nPi
Step-by-step explanation:
Since Pi represents the probability of observing the ith outcome
The number of independent trials n = k>3 :
Expected outcome of each count will be the product of probability of the ith outcome and the number of the corresponding trial.
Hence, Expected count (Ei) = probability of ith count * n
Ei = nPi
The formula of an expected count is given by .
