Answer: 3/20
Concept:
When encountering questions that ask for [how much longer A comparing to B], the basic operation would be the value of A subtracted by the value of B.
Solve:
Given information
Maggie study time = 2/5 hours
Julie study time = 1/4 hours
Given expression deducted from the concept
Maggie (study time) - Julie (study time)
Substitute values into the expression
2/5 - 1/4
Find the denominators' Least Common Multiple (LCM)
First five multiples of 5: 5, 10, 15, 20, 25
First five multiples of 4: 4, 8, 12, 16, 20
Since [20] is the first term that appears in both multiples, it would be the LCM of 4 and 5
Convert the fractions to common denominator
2/5 = (2 × 4) / (5 × 4) = 8 / 20
1/4 = (1 × 5) / (4 × 5) = 5 / 20
Simplify by subtraction
=8/20 - 5/20
=(8 - 5) / 20

C = i + 2j - k

Answer:
f(0)=g(0) is the only correct option.
Step-by-step explanation:
The value of the function is essentially the value of y in this graph. So it suffices to answer by checking and comparing the y values of both functions.
f(0)=g(0) must be correct as they are on the same point (and thus has the same y value)
f(-2)=4 but g(-2)=-4. So option b is wrong.
Option c is also wrong by checking the values.
The required, true statment among the option for the given graph of functions is f(0)=g(0). Option A is correct.
What are functions?Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.
Here,
From the graph given, it is seen that the two lines intersect at a common point (0, -2)" which means that on the graph provided, there are two lines that meet or cross each other at a specific point in the coordinate plane, which has an x-coordinate of 0 and a y-coordinate of -2. The intersection point (0, -2) is where the x and y values of the two lines are equal, meaning they share a common solution.
This point is sometimes called the point of intersection or the solution to the system of equations formed by the two lines.
Following the above discussion, we can conclude that f(0) = g(0). Option A is correct.

The third answer choice is correct, remember that a shape is not a rectangle or square if it doesn't have four 90 degree angles.
if SP is equal to rupees 400 and loss percent is 20% find CP
100-20=80%=400
[tex]\\ \rm\longmapsto 80\%\:of\:CP=400[/tex]
[tex]\\ \rm\longmapsto CP=400\times \dfrac{100}{80}[/tex]
[tex]\\ \rm\longmapsto CP=5(100)[/tex]
[tex]\\ \rm\longmapsto CP=500[/tex]
Step-by-step explanation:
Given,
S.p.=Rs400
Loss percent(L%) =20%
C.p.=?
We know,
S.p. =(100-L) % of c.p.
or,400=(100-20)% *c.p.
or,400=80% *c.p.
or, 400=80/100*c.p.
or,c.p.=Rs.500
Here, c.p.=Rs.500

x^3-8x^2<0
9514 1404 393
Answer:
(-∞ < x < 0) ∪ (0 < x < 8)
Step-by-step explanation:
Factoring the inequality gives you ...
x²(x -8) < 0
The x-intercepts of the curve described by the left-side expression are 0 and 8, values that make the factors zero. The intercept at x=0 has multiplicity 2, so the curve does not cross the x-axis there.
Since this is an odd-degree polynomial with a positive leading coefficient, its general shape is rising to the right. That means the left-side expression will be negative for x-values less than the first x-intercept, and for x-values between the x-intercepts.
The solution is ...
(-∞ < x < 0) ∪ (0 < x < 8)
the inequality -3n<12 is equivalent to
a. n < 4
b. n < -4
c. n > 4
d. n > -4
e. n > 36
Answer: D. n > -4
Step-by-step explanation:
Given
-3n < 12
Divide both sides by -3. REMEMBER to change the [>,<] signs when multiplying or dividing a negative term
-3n / -3 > 12 / -3
n > -4
Hope this helps!! :)
Please let me know if you have any questions
Hey there! I'm happy to help!
Inequalities are solved like normal equations with a few extra rules.
So, we could simply divide both sides by -3 to get our answer, but n<-4 would actually be incorrect. With inequalities, dividing by a negative number means you have to flip the inequality sign. This is because you turn the other side negative so you need to adjust the inequality sign to match it.
So, our final answer will actually be n>-4.

Maria has four hours of free time each day. She can spend it studying or working at the Wang's Chinese
Kitchen for $6.50 per hour. Curve A illustrates the trade-off between school grades and the wages Maria
could eam.
What are the maximum wages Maria could eam if she works five days a week?
b. What grades can she expect if she works 10 hours each week?
What advice would you give Maria if she were eaming $50 each week and making Ds?
a
c.
Opportunity cost is the cost of the alternative forgone;
The cost of Maria spending more time on her studies is the wages from working in the kitchen which she does not earn and vice versa
The correct values are as follows:
a. The maximum wages Maria could earn is $130
b. The grades she can expect if she works 10 hours each week is grade C
c. She should make a decision to either quit school or quit her job
d. To become a pharmacists, she should study more and quit her job
To become a restaurant owner/manager, she should develop her restaurant/managerial skills more at the
The reason for the above responses are as follows:
The known parameters are:
The number of hours of free time Maria has each day = 4 hours
The activities Maria can use the four hours for = Studying or working at the Wang's Chinese kitchen
The amount she can earn per hour working = $6.50 per hour
Question a. Required;
The maximum wages Maria could earn working 5 days a week
Solution;
Taking the each unit on the horizontal axis of the attached graph as one day. There are 5 units which equal 5 days
if she works for the five days, she spends all the available time working and she earns maximum wage on the graph which is $130The maximum wages Maria could earn if she works five days a week = $130
b. Required:
The grade she can expect by working 10 hours a week
Solution:
The number of hours available each week = 5 × 4 hours = 20 hours
If she works 10 hours each week, she spends the remaining 10 hours studying which is half of her available time
The grades she can expect by working 10 hours each week (half of her spare time) is giving by the value of the graph at the middle of the of half the length of the horizontal axis values which is grade C
c. Required:
The advice for Maria if she is earning $50 each week and is making Ds
Solution:
If Maria is earning $50 each week, the number of days she is working = One day
The number of days she spends reading = 4 days
In order to improve her grades, she should increase the number of days she spends reading, and therefore, she should spend more than 4 days or the 5 days reading and she should stop working and forgo the $50 for a grade C
Therefore;
Maria has to make a decision to either quit school or quit her job
d. Part of the question that can be included as seen from a similar question online is as follows;
The advice for her if she is interested in becoming a pharmacists or a restaurant owner/manager
If she is interested in becoming a pharmacist, she should stop working and focus on her studies; Quit her job
If she interested in becoming a restaurant owner or manager, she should spend less time reading and spend much of her time at the Wang's Chinese kitchen to develop are restaurant business skills;

Find the distance between the two points rounding to the nearest tenth. (2,-8) and (5,-6)
9514 1404 393
Answer:
3.6
Step-by-step explanation:
The distance formula is used for this purpose:
d = √((x2 -x1)² +(y2 -y1)²)
d = √((5 -2)² +(-6 -(-8))²) = √(3² +2²) = √13
The distance is √13 ≈ 3.6 units.
