Answer:
[tex]6+2.5r\leq 50[/tex]
Step-by-step explanation:
Hi!
The options regarding the inequalities are not listed, though we can still proceed to write the inequality.
From the problem statement you cannot spend more than $50
and you are charged admission fee of $6 flat
a ride cost $2.50 per ride
the number of rides is given as r
yet in all you must not go beyond your limit
Therefore the inequalities can be presented as
[tex]6+2.5r\leq 50[/tex]
Answer:
2.5r + 6 ≤ 50
Step-by-step explanation:
Solve each of the following equations. a. 24 = -3 + 3n b. 11 + 4x = x - 10 c. -216 = 1 + 7(1 + 8m) d. 3p - 3(2 - 2p) = 34 + 4p You must show all of your work to receive credit.
Answer:
a. 24 + 3 =3n
27=3n
27/3 =3n/3
9=n
b.4x-x = -10 -11
3x = -21
3x/3 = -21 / 3
x = -7
c. -216 = 1 + 7 + 56m
-216 - 1 - 7 = 56m
- 224 = 56m
- 224 / 56 = 56m / 56
- 4 = m
d. 3p - 6 + 6p = 34 + 4p
3p + 6p - 4p = 34 + 6
5p = 40
5p / 5 = 40 / 5
p = 8

this is the digit that tells you whether to round up or down
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.

compare the following fraction
4/3 and 5/2
-3/2. -4/5
Answer:
Step-by-step explanation:
to compare them, we need to convert them into like fractions
4/3 and 5/2
lcm of 3 and 2 is 6
4/3 × 2/2 = 8/6
5/2 × 3/3 = 15/6
15/6 is greater than 8/6
so 5/2 is greater than 4/3
similarly,
-3/2 and -4/5
we need to convert them into like fractions
lcm of 2 and 5 is 10
-3/2 × 5/5 = -15/10
-4/5 × 2/2 = -8/10
-8/10 is greater than -15/10
so -4/5 is greater than -3/2

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)
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.

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?
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.

Suppose there are n independent trials of an experiment with k3 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?
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 .
[tex]E_i=np_i[/tex]
Suppose there are n independent trials of an experiment with k > 3 mutually exclusive outcomes,

What is the measure of AngleDCF? Three lines extend from point C. The space between line C D and C E is 75 degrees. The space between lines C E and C F is 54 degrees. The measure of AngleDCF is degrees.
Answer:
129 degrees

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°
Hence, the measure of ∠DCF is 132°.

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
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]

The wheel revolves at 4 revolutions per second.
Hence the wheel will go forward [tex]4\times14\pi[/tex] inches in one second

Find the solution (in explicit form) for the following initial value problem: y 0 = xy3 (1 + x 2 ) − 1 2 y(0) = 1.
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 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?
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.
