Answer:
07:45 pm
Explanation:
Steven landed in Orlando after the sum of the following time
3 hours and 45 minutes
2 hours and 30 minutes
1 hour and 30 minutes
If we add the hours and the minutes, we get:
3 hours + 2 hours + 1 hour = 6 hours
45 minutes + 30 minutes + 30 minutes = 105 minutes
But 1 hour = 60 minutes, so
6 hours and 105 minutes = 7 hours and 45 minutes
because
105 - 60 = 45
Since the flight left Boston at 12:00 pm, it was 07:45 pm when Steven landed in Orlando.

[tex]\begin{gathered} y=875(1+2\%)^x \\ =875(1+\frac{2}{100})^x \\ =875(1+0.02)^x \\ y=875(1.02)^x \end{gathered}[/tex]The correct choice is D.
Rita is a software saleswoman. Let y represent her total pay (in dollars). Let x represent the number of copies of English is Fun she sells. Suppose that x and y are related by the equation 1900+110x=Y.
, if she does not sell any of English,x = The number of copies of English is Fun she sells
y = Total pay
[tex]y=1900+110x[/tex]Therefore,
a.
Her change in total pay for each copy of English is fun can be computed below.
(0, 1900) (1, 2010)
[tex]m=\frac{2010-1900}{1-0}=110[/tex]Her change in total pay for each copy of English is fun she sells = $110
b.
Her total pay if she does not sell any of English is fun is the y-intercept. Therefore,
[tex]\begin{gathered} y=1900+110x \\ y=1900+110(0) \\ y=\text{ \$1900} \end{gathered}[/tex]Her total pay if she does not sell any of English is fun = $1900
Note you can model it to the slope-intercept equation.
[tex]\begin{gathered} y=mx+b \\ \text{where} \\ m=\text{change in total pay for each copy of English is fun she sells } \\ b=\text{Her total pay if she does not sell any of English is fun} \end{gathered}[/tex]
If there are three black, four white, two blue, and four gray socks in a drawer, what would be the probability of picking a black sock as a fraction in simplest form?1/103/91/33/13
The probability of getting a black sock out of the drawer is given by the ratio between the amount of black socks in the drawer by the total amount of socks in the drawer.
We know that we have 3 black socks, now we just need to calculate the total amount of socks. We have three black, four white, two blue, and four gray socks in a drawer, then, the total is given by
[tex]3+4+2+4=13[/tex]We have a total of 13 socks in the drawer, therefore, the probability of getting a black sock out of the drawer is given by
[tex]\frac{3}{13}[/tex]And this is the fraction in the most simplified version.

Of there are 2,000 pounds per ton, how many total tons of corn can be placed in the bin?
ANSWER :
a. 628 cubic foot
b. 52 cubic foot
c. 1.17 ton
EXPLANATION :
The volume formula of a cylinder is :
[tex]V=\pi r^2h[/tex]The volume formula of a cone is :
[tex]V=\frac{1}{3}\pi r^2h[/tex]From the problem, we have a diameter of 10 ft, so the radius is r = 5 ft
Cylinder's height is 8 ft and cone's height is 2 ft
a. volume of cylinder part :
[tex]\begin{gathered} V=\pi(5)^2(8) \\ V=628ft^3 \end{gathered}[/tex]b. volume of cone part :
[tex]\begin{gathered} V=\frac{1}{3}\pi(5)^2(2) \\ V=52ft^3 \end{gathered}[/tex]c. The combine volume is 628 + 52 = 680 cubic foot
A dry corn weighs 45 lbs per cubic foot.
That will be :
[tex]52ft^3\times\frac{45lbs}{ft^3}=2340lbs[/tex]There are 2000 pounds per ton, so that will be :
[tex]2340lbs\times\frac{1ton}{2000lbs}=1.17ton[/tex]The sale price S (in dollars) of an item is given by the formula S=L-rL, where L is the list price (in dollars) and r is the discount rate (in decimal form).Solve the equation for r.
ANSWER
[tex]r=1-(\frac{S}{L})[/tex]EXPLANATION
Given;
[tex]S=L-rL[/tex]To make r the subject of formula, flip the equation
[tex]rL=L-S[/tex]Divide both sides by L;
[tex]\begin{gathered} \frac{rL}{L}=\frac{L-S}{L} \\ r=\frac{L-S}{L} \\ =\frac{L}{L}-\frac{S}{L} \\ =1-\frac{S}{L} \end{gathered}[/tex]Write the equation of a perpendicular and parallel line to the following: (in picture)
anIf we have an equation of the form
[tex]y=mx+b[/tex]then the equation of the perpendicular will be
[tex]y=-\frac{1}{m}x+c[/tex]where c is any arbitrary constant determined by the point the line must pass through,
Now in our case, we have
[tex]y=-10x+20[/tex]Therefore, the equation of the perpendicular line will be
[tex]y=\frac{1}{10}x+c[/tex]We must choose c such that the above line passes through (-2,2).
Putting in y = 2 and x = 2 from (-2, 2) gives
[tex]2=\frac{1}{10}(-2)+c[/tex][tex]2=-\frac{1}{5}+c[/tex][tex]\therefore c=\frac{11}{5}.[/tex]Hence, the equation of a line perpendicular y = -10x + 20 and passing through (-2, 2) is
[tex]y=\frac{1}{10}+\frac{11}{5}[/tex]Now we find the equation of a line parallel to y = -10x+20 and passing through (-2,2).
Now, the slope of the parallel line is the same as that of the original equation; therefore the equation for the parallel line we have is
[tex]y=-10x+k[/tex]We find k by using the point (-2,2) and substituting x = -2 and y = 2 into the above equation to get
[tex]2=-10(-2)+k[/tex][tex]2=20+k[/tex][tex]\therefore k=-18.[/tex]Hence, the equation of the parallel line is

Melissa and brain are at the base of a mountain.melissa hikes to a location 27 meters above sea level.brain hikes to a location 21 meters below sea level. what us the diffrence if the hikers altitudes?
The point at the base of the mountain is described as point zero, that is they are still at sea level. If Melissa now moves to a position 27 metres above sea level, that is positive 5, assuming we are now measuring along a vertical number line. Brian however moves to a location which is 21 metres below sea level, or negative 21 along the vertical number line. Since we are measuring distances, the distance from point zero to both hikers' new position will be measured in absolute values only, that is both distances will be measured as positive.
Hence the distance between Melissa and Brian is;
Distance = 27 + 21
Distance = 48
The difference in altitude between both hikers is 48 metres
Graph the function for the given domain.-2x - 10y = 10 , D: (-5, 0, 5, 10)
In order to graph the function, we need first to find the coordinates of the points. To do so, we need to apply the values of x given in the domain and calculate the corresponding values of y. So we have that:
[tex]\begin{gathered} x=-5\colon \\ -2\cdot(-5)-10y=10 \\ 10-10y=10 \\ -10y=0 \\ y=0 \\ \\ x=0\colon \\ -2\cdot(0)-10y=10 \\ -10y=10 \\ y=-1 \\ \\ x=5\colon \\ -2\cdot(5)-10y=10 \\ -10-10y=10 \\ -10y=20 \\ y=-2 \\ \\ x=10\colon \\ -2\cdot(10)-10y=10 \\ -20-10y=10 \\ -10y=30 \\ y=-3 \end{gathered}[/tex]So the points are (-5, 0), (0, -1), (5, -2) and (10, -3).

To get the probability of an event, we need two things:
1. The total number of possibilities
2. The total number of possibilities considered favorable
For the first event A which is landing on a number less than 3, we only have one favorable possible which is landing on 2.
For the second event B which is landing on a 5, we also only have one favorable possible which is landing a 5 itself.
Now, for both events, the total number of possibilities is 4.
So, the probability of landing on a number less than 3 is 1/4 while the probability of landing on a 5 is also 1/4.

7. Quinn had 3 more than two times the number of marbles Rowan has. Together they have 77marbles. How many marbles does each child have?
Explanation:
Let the number of marbles Rowan has = x
Two times x = 2x
3 more than two times the number of marbles Rowan has = 2x + 3
Quinn = 2x + 3
Together they have = 77 marbles
Rowan marbles + Quinn marbles = 77
x + (2x + 3) = 77
x + 2x + 3 = 77
Collect like terms:
3x = 77-3
3x = 74
Divide through by 3:
x = 74/3
x = 24.7
6-4x=6x-8x-8. what does x =
Start by balancing it out.
First +4x to both sides:
6=6x-4x-8
Then +8 to both sides:
14=6x-4x
As 6x-4x=2x
14=2x
Finally, divide both sides by 2:
7=x
So, the answer is x = 7
