Answer:
1. q = p - mn
2. c = -6
3. 10
Step-by-step explanation:
1.
[tex]mn=p-q\\\textsf{add q to both sides}\implies mn + q = p\\\textsf{subtract mn from both sides}\implies q = p-mn[/tex]
2.
[tex]5c+23=c-1\\\textsf{subtract 23 from both sides}\implies5c=c-24\\\textsf{subtract c from both sides}\implies4c=-24\\\textsf{divide both sides by 4}\implies c=-6[/tex]
3.
[tex]4f^2-g\\\implies 4(2)^2-3=13\\\\3f^2-3g\\\implies 3(2)^2-(3 \times3)=3\\\\13-3=10[/tex]
Find the difference
(2/7x-3) - (5/2+1/5y)
Step-by-step explanation:
Distribute the negative sign:
[tex]\frac{2}{7} x-3 -5/2-\frac{1}{5}y[/tex]
From the given, we can only find the difference with the integers.
Subtract the integers:
[tex]\frac{2}{7} x-\frac{1}{5}y-0.5[/tex]
How do I solve other problems like this?
y=mx+b
Answer:
y = -2x - 3
Step-by-step explanation:
in the equation y = mx + b,
m = slope b = y-intercept
The y-intercept is provided in the point, (0, -3), because that is where it crosses the y. You're y-intercept is -3
Now you need to find slope. You need to find the difference between these two points to find slope.
[tex]-2+0 = -2[/tex]
[tex]1-3=-2[/tex]
so your slope is going down by 2 and to the left by 2.
Hope this helps! Might be wrong. Try with another example and tell me if it works. <3
Answer: B
Step-by-step explanation:
m is the value of the slope between the two points on the graph
If the two coordinates is (x1,y1) and (x2,y2), the slope is (y1-y2) / (x1-x2)
So the slope for this question is (1-(-3)) / (-2-0) = -2 so the answer is B
this is the answer ...
yea that is right, not sure why it says it's wrong, I'm sorry must be so frustrating

What is the volume of this sphere?
Use a ~ 3.14 and round your answer to the nearest hundredth.
6 m
Answer:
113.1
Step-by-step explanation:
Using the volume (for sphere) formula:
V = (4/3)*pi*(r^3)
You can plug in the radius (diameter/2, the diameter is 6m) to get a volume of 113.1.
Answer:
113.04m³
Step-by-step explanation:
[tex]Solution,\\\\Diameter(d)=6m\\\\Radius(r)=6m/2=3m\\\\Now,\\\\Volume=\frac{4}{3} \pi r^{3} \\\\Volume=\frac{4}{3} *3.14*(3m)^{3} \\\\Volume=113.04m^{3}[/tex]
Would you prefer a fully taxable investment earning 8.1 percent or a tax-exempt investment earning 6.1 percent
Answer:
Assuming that all other factors are equal, (and they never are), I would prefer a 20% or more ROI investment, located in a tax deferred, or tax exempt account!
Assuming that you are for some reason entirely unmotivated to look for better investments than the two you have pointed out, why not just buy the 8.1% investment with your IRA, Roth IRA, 401(k), SEP IRA, or spousal IRA funds?
You can then pretty much ignore your tax rate. Just move over any portion of your standard deduction that remains unused near the end of the year, via a Roth conversion. You will pay no additional taxes, and the money converted will forever remain free of RMDs, (which will otherwise occur later on), for the rest of your life!
Step-by-step explanation:
Use your now freed up taxable money to invest in tax free transactions, (similar to the effect of having a periodic Roth IRA), and live happily ever after!
As always, upvote and follow me, either if you are entertained by my answers, or, if you are sufficiently curious to investigate my other answers posted on Quora, and realize that you COULD be making FAR MORE money with your investments than you have been!
Thank you for reading and I hope it helps
Travis spies an owl in a tall tree. He estimates the height of the tree to be 85 feet and the angle of elevation to the bird from where he stands to be 68°. The leaves on the tree make it difficult for Travis to watch the bird, so he takes several steps away from the tree to get a better view. He now estimates his angle of elevation to be 41°.
How many feet did Travis step back to gain a better view of the bird? Round your answer to the nearest hundredth of a foot.
Using the slope concept, it is found that he stepped back 63.44 feet.
What is a slope?The slope is given by the vertical change divided by the horizontal change.
It's also the tangent of the angle of depression.
Initially, we have that:
The vertical change is of 85 feet.The horizontal change is his distance d.The angle is of 68º.Hence:
[tex]\tan{68^{\circ}} = \frac{85}{d}[/tex]
[tex]d = \frac{85}{\tan{68^{\circ}}}[/tex]
[tex]d = 34.34[/tex]
When he stepped back, the angle was of 41º, hence:
[tex]\tan{41^{\circ}} = \frac{85}{d}[/tex]
[tex]d = \frac{85}{\tan{41^{\circ}}}[/tex]
[tex]d = 97.78[/tex]
97.78 - 34.34 = 63.44.
Hence he stepped back 63.44 feet.

A bad punter on a football team kicks a football approximately straight upward with a velocity 90 ft/sec. The height h (in feet) of the ball t seconds after being kicked is given by h = –16t2 + 90t + 4. Find the time(s) at which the ball is at a height of 90 feet. Round to one decimal place.
The time it will take the ball to reach a height of 90feet is 1.2 and 4.4secs
How to calculate the height of a ballGiven the height h (in feet) of the ball t seconds after being kicked expressed as:
h = –16t2 + 90t + 4.
If the ball is at a height of 90feet, hence:
90 = –16t2 + 90t + 4
–16t2 + 90t + 4 - 90 = 0
16t^2 -90t + 86= 0
8t^2 -45t + 43= 0
Factorizing the result to get the values of t:
[tex]t=\frac{45 \pm \sqrt{45^2-4(43)(8)} }{16} \\t=\frac{45 \pm \sqrt{2,025-1376} }{16} \\t=\frac{45 \pm {25.47}}{16} \\t=4.4s \ and\ 1.22secs[/tex]
Hence the time it will take the ball to reach a height of 90feet is 1.2 and 4.4secs

A cell phone plan charges $45.50 a month, plus $0.05 per text message. Write and graph an expression to find how many text messages, x, can be sent while still keeping the monthly bill under $60.
Answer:
289 messages
equation: [tex]y=0.05x+45.5[/tex]
graph: attached below
Step-by-step explanation:
We can write this in slope-intercept form, or [tex]y=mx+b[/tex]. Since x is defined as the #of text messages, and 0.05 is the cost of a text message, 0.05 will be m. 45.5 is the base price, or the y-intercept, so it will be b.
Plugging in these numbers, we get [tex]y-0.05x+45.5[/tex]
now we make y = 60, since that is the total amount they have
[tex]60=0.05x+45.5\\14.5=0.05x\\x=290[/tex]
So, they can send 290 messages for 60, but they need the bill under 60, so 1 text message less will be 289, and that's enough.

24 is 3/4 of ___
Find the answer
Answer:
24 is 3/4 of 32.
Step-by-step explanation:
if you understand:
24 divided by 3 (3 in 3/4) is 8.
8 x 3 = 24, so if we need to fill in the extra 1 in 3/4 (making it 4/4), we would need to add another 8. 24 + 8 = 32. (u can look up ' what is 3/4 of 32 too ')

expression that gives the cost for a trip of d miles?
a) Algebraic Expression:
b) How much would it cost to travel 23 miles?
Answer Sentence:
Answer:
A. ok so lets make a alebra equation
2.75d+6.26
first of all they charge a certain amount per mile so thats why we multiply that by the number on miles then we add the base price of 6.26
B. ok so lets just plug in
77.76
Hope This Helps!!!
(a)
Given the info that Tito charges a $6.26 fee for a ride plus $2.75 for every ride, we derive
Y is the amount of money in total
X is the amount of miles for each ride
Algebraic Expression: Y=2.75X+6.26
(b)
Plugging in 23, we get
Y=2.75(230+6.26
Y=69.51
Answer Sentence: It would take $69.51 to travel 23 miles on TIto's taxi.
