A point where 2 rays meet to form an angle
-2(v- 2) =-3 -22
What’s the answer?
Answer:
v= 29/2
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
−2(v−2)=−3−22
(−2)(v)+(−2)(−2)=−3+−22(Distribute)
−2v+4=−3+−22
−2v+4=(−3+−22)(Combine Like Terms)
−2v+4=−25
−2v+4=−25
Step 2: Subtract 4 from both sides.
−2v+4−4=−25−4
−2v=−29
Step 3: Divide both sides by -2.
−2v
−2
=
−29

Shandra is on vacation and wants to buy souvenirs for at least eight friends. A postcard book costs $2.50 and a magnet costs $4.00. She can spend up to $30 all together. Which system of inequalities represents the situation?
Answer:
[tex]2.5p + 4m \leq 30[/tex]
Step-by-step explanation:
Given
Poster = $2.50
Magnet = $4.00
Amount = Up to $30
Required
Determine the inequality
Represent posters with p;
This implies that she can buy 2.50p worth of posters
Represent magnets with m
This implies that she can buy upto 4m worth of magnets
The question says she can spent up to $30;
This implies that she can spend at most $30 and this can be mathematically represented as [tex]\leq 30[/tex]
Bringing the parameters together; we have
[tex]2.5p + 4m \leq 30[/tex]
The system of inequalities that represents the situation is [tex]2.5x+4y\leq 30[/tex] and this can be determined by using the given data and arithmetic operations.
Given :
A postcard book costs $2.50 and a magnet costs $4.00.Shandra can spend up to $30 all together.Let the total number of postcards be 'x' and the total number of magnets be 'y'. The following steps can be used to determine the inequalities that represent the situation:
Step 1 - Multiply 2.5 with x.
2.5x
Step 2 - Multiply 4 with y.
4y
Step 3 - Now, add the above two expressions.
2.5x + 4y
Step 4 - Now, apply the inequality.
[tex]2.5x+4y\leq 30[/tex]
The system of inequalities that represents the situation is [tex]2.5x+4y\leq 30[/tex].

A freight train, traveling at a speed of 18.0 m/s, begins braking as it approaches a train yard. The train's acceleration while braking is –0.33 m/s2 . What is the train's speed after 23s?
Answer:
v = 10.41 m/s
Step-by-step explanation:
using one of the equations of motion:
v = u + at
where v= final velocity
u= initial velocity
a = acceleration
t = time
u = 18.0 m/s
v = ?
a = –0.33 m/s2
t = 23s
v = 18.0 + (–0.33 x 23)
v = 18.0 + (-7.59)
v = 10.41 m/s

-2.75 is classified as?Select all that apply Natural Number Whole Number Integer Rational Number
Answer:
Rational Number
Step-by-step explanation:
It is not a natural number as natural numbers are the counting numbers we use and therefore only encompass positive integers,which - 2.75 is not. Whole numbers and integers do not include decimals and fractions, therefore - 2.75 is not included either does to its decimal. Finally it is a rational number because it can be properly expressed as a fraction (-2.75/1). Therefore it is just a rational number from this list.

imagine an investigation in which 40 students were asked to determine their chronotype by choosing from among four chronotypes instead of three: morning person, night person, neither, or both. If there is no relationship between chronotype and birth month, about what fraction of the students would you expect to pick the chronotype that matches their birth month? why do you think this?
Step-by-step explanation:
A chronotype is a behavioral manifestation of an underlying circadian rhythms of the myriad physical processes.
The chronotype word may be defined as an individual's natural tendency to remain active mostly at certain times of the day. Some people remain active and alert in the early time of the day and some are alert and active in the late night.
The chronotypes are : Morning person, night person, neither/both.
It is assume that the birth month and year of a person influences his or her chronotype. But if birth month is not related to theses personality traits of a person, then it can be expected that nearly 1/3rd of the fraction of the students in class picks the chronotype which corresponds to their birth type.
Seventy-five (75) customers at Crummy Burger today were entered in a drawing. Three names will be drawn, and each will win a prize. Determine the number of ways that the prizes can be distributed if all 3 prizes are a $10 gift card.
Answer:
the number of ways in which the prizes are allocated is 67,525
Step-by-step explanation:
Given that
Number of customers = 75
Number of prizes = 3
And, the value of gift card = $10
Based on the above information,
The number of ways in which the prizes are allocated is shown below:
[tex]=^{75} C_3[/tex]
= [tex]\frac{75!}{(3!\times(75-3)!}[/tex]
After solving this the number of ways that came is 67,525
hence, the number of ways in which the prizes are allocated is 67,525

If Jesse wants to buy a $75,000 10-year term life insurance policy, and the annual premium rate (per $1000 of face value) for his age group is $2.34, how much is Jesse’s annual premium?
Step-by-step explanation:
Since it is given that it costs $2.34 for every $1000 face value, and it was given that he wanted to buy a $75000 plan, multiplying $2.34 by 75 (75000 includes 75 $1000 face value), it should yield us the annual premium.
2.34 * 75 = $175.50
We don't need to multiply it by 10 years as only the annual premium is being solved for.

the slope-intercept form of an equation is y = mx + b. rewrite the equation in terms of the slope m
Answer:
[tex]\displaystyle m=\frac{y-b}{x}[/tex]
Step-by-step explanation:
We are given the equation:
[tex]y=mx+b[/tex]
And we want to rewrite it in terms of m.
We can subtract b from both sides:
[tex]y-b=mx[/tex]
Finally, dividing both sides by x yields:
[tex]\displaystyle m=\frac{y-b}{x}[/tex]
In conclusion:
[tex]\displaystyle m=\frac{y-b}{x}[/tex]

Step-by-step explanation:
Step 1: Write out equation
3y + 2x = -1
Step 2: Subtract 3y on both sides
3y - 3y + 2x = -1 - 3y
2x = -1 - 3y
Step 3: Divide both sides by 2
2x/2 (-1 - 3y)/2
x = -1/3 - 3/2y
