Jane is a computer science major planning to take 4 courses next semester. She is planning to take 2 computer science courses and 2 courses from other areas. How many different schedules can she build?
Answer: 24 schedules.
Step-by-step explanation:
Given data:
Courses planning to take = 4
Computer courses = 2
Courses from other areas = 2
Solution:
This problem can be solved using permutation.
For Computer science courses.
npr = n! / ( n - r )!
Where n = 4
r = 2
4p2 = 4!/( 4-2)!
= 4!/2!
= 12
For other courses.
Where n = 4
r = 2
4p2 = 4!/( 4-2)!
= 4!/2!
= 12
Jane can have a total of 24 different schedules.
In RST, R = 23* and S = 136*. Which list has the sides of RST in order from shortest to longest?
RS, TR, ST
TR, ST, RS

TR, RS, ST
RS, ST, TR
Answer:
RS, ST, TRStep-by-step explanation:
The third angle measures:
T = 180° - (136° + 23°) = 21°Angles and opposite sides are:
S = 136° → TRR = 23° → STT = 21° → RSThe greater the angle, the greater the opposite side, therefore the sides in increasing order will be:

First Degree Equations
A first-degree equation can have one, none, or infinitely many solutions.
An equation like
2x + 3 = -x + 6
Has one solution: x=1
An equation like:
4x + 2 = 4x + 1
Has no solutions because when trying to solve for x we get:
2 = 1
This equality is false and no value of x can make it true
Finally, the equation:
3x + 2 = x + 2x + 2
Has infiniteyl many solutions, because when trying to solve it, we get:
2 = 2
Which is true regardless of the value of x
The first given equation:3x + 9 + 4x + x = ??
can be simplified as:
8x + 9 = ??
For this equation not having solutions, we should have 8x plus any number but 9 on the right side of the equation:
8x + 9 = 8x -3, or
8x + 9 = 8x + 4
The second given equation:3x + 9 + 4x + x = ??
can be simplified as:
8x + 9 = ??
If the equation has one solution, the only condition is that we should not have 8x on the right side. Thus any of those will do:
8x + 9 = 3x + 9
8x + 9 = -x + 5
8x + 9 = 0
The third equation:3x + 9 + 4x + x = ??
can be simplified as:
8x + 9 = ??
For this equation to have infinitely many solutions, the right side must be exactly equal to the left side:
8x + 9 = 8x + 9
Shannon makes and sells picture frames. She charges different rates depending on the material she uses for the frame. Shannon sold a frame for $45. Which type of frame did Shannon sell? Use the drop-down menus to show and explain your answer.
Answer: Shannon sold the silver plated frame because 45 divided by 2.5 = $18, which is the wood frame rate.
STEP BY STEP EXPLANATION:

You buy butter for $3 a pound.
One portion of onion compote requires 1.7 oz of butter.
How much does the butter for one portion cost? Round to the nearest cent.
There are 16 ounces in one pound.
Set up a proportion and solve for x.
3/x = 16/1.7
16x = 3(1.7)
16x = 5.1
x = 5.1 ÷ 16
x = 0.31875
Rounding to the nearest cent, we get 30 cents.

a company makes two different-sized ice cream cones. The smaller cones are 3.5 inches tall and have a diameter of 3 inches. The larger cones are 5.1 inches tall and have a diameter of 4.5. inches. About how much greater, to the nearest tenth of a cubic inch, is the volume of the larger cone than the volume of the smaller cone?
9514 1404 393
Answer:
18.8 cubic inches
Step-by-step explanation:
The formula for the volume of a cone is useful:
V = 1/3πr²h
Where r is half the diameter, we can use r=d/2 to write this in terms of diameter:
V = 1/3π(d/2)²h = (π/12)d²h
For the given dimensions, the volumes are ...
large cone: v = (π/12)(4.5 in)²(5.1 in) ≈ 27.04 in³
small cone: v = (π/12)(3 in)²(3.5 in) ≈ 8.25 in³
Then the difference in volume is ...
(27.04 -8.25) in³ ≈ 18.8 in³
The larger cone has about 18.8 cubic inches more volume.

Answer:
Fourth Option
Step-by-step explanation:
In order to find the answer to this question you need to change the mixed number into a improper fraction and then add by finding the least common denominator (LCD).
[tex]-\frac{3}{4} +2\frac{3}{4}[/tex]
Convert into improper fraction:
[tex]2\frac{3}{4} =4\times2=8+3=11[/tex]
[tex]-\frac{3}{4} +\frac{11}{4}[/tex]
Since how the denominators are the same you can just add numerators:
[tex]-3+11=8[/tex]
[tex]=\frac{8}{4}[/tex]
Reduce:
[tex]8\div4=2[/tex]
[tex]4\div4=1[/tex]
[tex]=\frac{2}{1}[/tex]
[tex]\frac{2}{1} =2[/tex]
Hope this helps.

You and your four friends have $25 to spend on snacks. A medium size popcorn costs $2.50 and a medium soft drink costs $1.50. Write and graph an inequality that represents the numbers of medium boxes of popcorn and medium soft drinks you can buy.
Answer:
Step-by-step explanation:
Step one:
given
Total money at hand=$25
cost of one popcorn=n $2.5
cost of drink= $1.5
total number of friends plus you= 4+1= 5
let the total amount spent be y
y= 5(2.5)+5(1.5)
y=12.5+7.5
y=20

Answer:
d = sqrt(17)
Step-by-step explanation:
d = sqrt( x2 - x1)^2 + (y2 - y1)^2 )
d = sqrt( (4 - 5)^2 + (-3 - 1)^2 )
d = sqrt( (-1)^2 + (-4)^2 )
d = sqrt ( 1 + 16)
d = sqrt(17)
if the supply and demand functions for a commodity are given by p-q=10 and q(2p-10)=2100, what is the equilibrium price and what is the corresponding number of units supplies and demanded
Answer:
If p - q = 10, then p = 10 + q. Replace the other p with this:
q(2(10 + q) - 10) = 3600
q(20 + 2q - 10) = 3600
q(10 + 2q) = 360
The equilibrium point of a demand and supply function is the point where both functions are equal.
The equilibrium price is 40, and the corresponding demand is 30 supplies
Given
[tex]p- q = 10[/tex] --- the supply function
[tex]q(2p - 10) = 2100[/tex] --- the demand function
Make q the subject in [tex]p- q = 10[/tex]
[tex]q = p - 10[/tex]
Substitute [tex]q = p - 10[/tex] in [tex]q(2p - 10) = 2100[/tex]
[tex](p - 10)(2p - 10) = 2100[/tex]
Factor out 2
[tex]2(p - 10)(p - 5) = 2100[/tex]
Divide both sides by 2
[tex](p - 10)(p - 5) = 1050[/tex]
Open brackets
[tex]p^2 -10p - 5p + 50 = 1050[/tex]
[tex]p^2 -10p - 5p + 50 - 1050 =0[/tex]
[tex]p^2 -15p - 1000 =0[/tex]
Expand
[tex]p^2 -40p + 25p- 1000 =0[/tex]
Factorize
[tex]p(p -40) + 25(p- 40) =0[/tex]
Factor out p - 40
[tex](p+ 25) (p- 40) =0[/tex]
Solve for p
[tex]p = -25[/tex] or [tex]p = 40[/tex]
The price cannot be negative.
So: [tex]p =40[/tex]
Recall that:
[tex]q = p - 10[/tex]
[tex]q = 40 - 10[/tex]
[tex]q = 30[/tex]
Hence, the equilibrium price is 40, and the corresponding number of supplies is 30

xoxo, your highness...The probability of people liking hot or iced coffee is 0.61. Therefore, option C is the correct answer.
What is the probability?Probability can be defined as the ratio of the number of favourable outcomes to the total number of outcomes of an event.
We know that, probability of an event = Number of favourable outcomes/Total number of outcomes
Given that, according to sales records at a local coffee shop, 75% of all customers like hot coffee, 30% like cold coffee and 22% like both hot and iced coffee.
People like only hot coffee = 0.53
People like only iced coffee = 0.08
Customers like hot or iced coffee =0.53+0.08
= 0.61
Therefore, option C is the correct answer.
