They need to raise at least $1250 for the entire 8th grade to be able to go.Mrs Gotlib donates $600.To raise the rest of the money,SGA will sell candy bars for $5 each. Which inequality represents how many candy bars SGA will need to sell.
Please help me with this problem, i will give the max points.
Answer:
600+5c greater than or equal to sign 1250
Step-by-step explanation:
They need to raise at least 1250$ but they can also raise more than that and we do not know how many candy bars they will be able to sell.

15-3yi=1/2x+2i solve for x and y
Answer:
x=2(5−3iy−2i)
Step-by-step
Regroup terms.
5-3iy= \frac{1}{2} x+2i
Simplify \frac{1}{2}x\frac{x}{2}
5-3iy= \frac{x}{2}+2i
Subtract 2i from both sides.
5−3iy−2i= \frac{x}{2}
Multiply both sides by 2.
(5−3iy−2i)×2=x
Regroup terms
2(5−3iy−2i)=x
Switch sides
x=2(5−3iy−2i)
The solution for the variables x and y are 30 and -2/3 respectively:
Given the expression 15-3yi=1/2x+2i, to solve for the value of x and y, we need to compare the real and the imaginary sides as shown:
Comparing the real sides:
[tex]15=\frac{x}{2} \\x= 15\times 2\\x = 30[/tex]
For the imaginary sides:
[tex]-3yi=2i\\-3y = 2\\y = -\frac{2}{3}[/tex]
Hence the solution for the variables x and y are 30 and -2/3 respectively:

Dean has built a ferris wheel in his backyard. It has a diameter of 10 feet and completes 30 revolutions per minute. Sketch a quick graph and find the period of the function that describes the height above the ground of a seat on the outside edge of this ferris wheel.
Answer: Period = 2 seconds
Graph is shown below
========================================================
Explanation:
1 minute = 60 seconds
We have 30 revolutions every 60 seconds, so we can write the ratio
30 rev: 60 sec
Divide both parts by 30 to turn that "30 rev" into "1 rev"
30 rev: 60 sec
30/30 rev: 60/30 sec
1 rev : 2 sec
This tells us that each full revolution takes 2 seconds. This is the period of the ferris wheel. The period is the length of each cycle.
The cyclic or periodic nature of this motion heavily implies we'll be dealing with a sine or cosine function of some kind. Let's go with sine.
Side note: cosine is really a sine function in disguise (it's just a phase shifted version of it).
---------------------
The general sine curve equation is
y = A*sin(B(x-C)) + D
where
|A| = amplitudeB = 2pi/T with T being the periodC handles phase shifts (left and right shifting)D handles vertical shifting, and y = D is the equation of the midline---------------------
The wheel is 10 feet in diameter, so 10/2 = 5 is the radius. This is also the amplitude because it is the distance from the midline to either the highest point (10 ft) or lowest point (0 ft). So A = 5.
Since T = 2 is the period, this means,
B = 2pi/T
B = 2pi/2
B = pi
We don't have any phase shifts to worry about so C = 0.
The midline is D = 5 since this is halfway up
----------------------
Putting all the pieces together, we get this sine equation
y = A*sin(B(x-C)) + D
y = 5*sin(pi*(x-0)) + 5
y = 5*sin(pi*x) + 5
The graph is shown below.
x = time in seconds, y = height of the seat

Is 3125 a perfect cube ? If not find the smallest number by which 3125 must be multiplied so that the product becomes a perfect cube.
Answer:
Yes it is
Step-by-step explanation: 3125 is a prefect cube
Answer:
5
Step-by-step explanation:
3125 is not a perfect cube.
The cubes around it are 14^3=2744 and 15^3=3375.
It seems like the only way to find the smallest number to multiply 3125 to make it a perfect cube is to guess and check.
3125*2=6250 cube root is 18.4
3125*3=9375 cube root is 21.08
3125*4=12500 cube root is 23.2
3125*5=15625 cube root is 25, which makes it a perfect cube.
You have to multiply by 5 to make 3125 a perfect cube.

Last year Lenny had an annual earned income of $58,475. He also had passive income of $1,255, and capital gains of $2,350. What was Lenny’s total gross income for the year?
a.
$58,475
b.
$59,730
c.
$60,985
d.
$62,080
Answer:
d. $62,080
Step-by-step explanation:
Annual earned income = $58,475
Passive income = $1255
Capital gains = $2350
Unknown:
Total gross income for the year = ?
Solution:
Gross income is the some of all the income within a given period time.
Gross income = Annual income earned + Passive income + Capital gains
= $58,475 + $1255 + $2350
= $62,080
His gross income is $62,080
Answer:
His gross income is $62080
Step-by-step explanation:
Gross income, in other words, means total income. So if you want to find the gross income, you have to add ALL his earnings together.
$58475+$1255+$2350=$62080
And that is the final answer, since that his is only income earned.

Two cars leave the same point at the same time traveling in opposite directions. One car travels west at 20 mph and the other travels east at 60 mph. In how many hours will they be 280 miles apart?
-Please provide step by step :)
Answer:
3.5 hours
Step-by-step explanation:
It is given that,
Velocity of first car, v = 20 mph
Velocity of second car, v' = 60 mph
They are moving in opposite direction. Their relative speed is given by :
V = 20 mph + 60 mph = 80 mph
Distance, d = 280 miles
So,
[tex]t=\dfrac{d}{V}\\\\t=\dfrac{280}{80}\ h\\\\t=3.5\ h[/tex]
Hene, they will be 280 mile apart in 3.5 hours.
