The pilot of a Boeing 747 is instructed to climb from 8000 ft to a cruising altitude of 29,000 ft. If the plane ascends at a rate of
3500 ft/min, how long will it take to reach the cruising altitude?
=======================================================
Explanation:
The plane needs to go up 29,000-8,000 = 21,000 feet
It does so at a rate of 3500 ft per min
So it needs 21000/3500 = 6 minutes to get to the proper height.
---------
You can think of it like the equation
3500x = 21000
where x is the number of minutes needed. Dividing both sides by 3500 solves to x = 6.
-----------
Or you could think of it like this
1 minute = 3500 feet
1/3500 minute = 1 foot (divide both sides by 3500)
1 foot = 1/3500 minute
21000 feet = 21000/3500 minute (multiply both sides by 21000)
21000 feet = 6 minutes
This shows that to go up 21000 feet, the plane needs 6 minutes to do so.

At a baseball game, hot dogs cost $2.25 and drinks cost $1.75. The total cost, t, for h hot dogs and d drinks can be described by the equation t=2.25h+1.75d. If Costas spent $18.25 and bought 5 hot dogs, how many drinks did he buy?
Answer:
He bought 4 drinks
Step-by-step explanation:
18.25= 2.25(5)+1.75d
18.25= 11.25+ 1.75d
18.25-11.25= 7
7= 1.75d
7/1.75
4=d
Answer:
4 drinks
Step-by-step explanation:
t = 2.25h + 1.75d
T = Total Cost
H = Hotdogs
D = Drinks
We have our total cost, which is $18.25 dollars
18.25 = 2.25h + 1.75d
We know Costas bought 5 hotdogs, so replace h with 5 and multiply :
2.25(5)
==> 11.25
Now that 11.25 dollars has been made, let's see how much money we need left to fit for the drinks.
18.25 - 11.25
==> 7
We need 7 dollars worth of drinks, so divide the cost by the amount we need to have.
7 / 1.75
==> 4
Castos needs to buy 4 drinks.

Factoring Trinomials in Standard form x^2+2x=-1
Answer:
(x + 1)(x + 1) = 0 OR (x + 1)^2 = 0
Step-by-step explanation:
First, we need to get the trinomial x^2 + 2x = -1 all on one side of the equation.
x^2 + 2x = -1
x^2 + 2x + 1 = -1 + 1
x^2 + 2x + 1 = 0
Now that the trinomial is on the left-hand side, let's factor the equation.
x^2 + 2x + 1 = 0
(x + 1)(x + 1) = 0
We can simplify this factored trinomial further to be:
(x + 1)(x + 1) = 0
(x + 1)^2 = 0

John Maynard Keynes and Karl Marx would agree most about the answer to
which question?
O A. Should governments take total control over economies?
B. Are precious metals a good measure of economic strength?
O C. Do free market economies create problems for workers?
D. Is it right for strong countries to control weaker colonies?
Answer:
Option C: Do free market economies create problems for workers?
Step-by-step explanation:
There was a law called Say's law which states that capitalist production generates its own markets, and therefore, there can't possibly be any gluts or overproduction of goods in relation to market demand.
Now, keynes and marx rejected this say's law because they both believed that gluts or overproduction may likely occur.
They believed that this law would make capitalists own nothing but the right to sell their labor in exchange for wages.
That due to the capitalists competition with themselves for profits, it would squeeze as much work as possible out of the working class people at the lowest possible price and that this competition would cause some capitalist firms to fail, and thereby increasing unemployment among the working class.
Thus, it's clear this was an answer to the question on whether free market economies create problems for workers.
Answer:
A.Should government take total control over economies

Required
Approximate
Approximating to the nearest hundredth implies that, only to digits after the decimal point is needed
This is:
191._ _
The third digit after the decimal point will approximated using the approximation rule;
Since, the third digit after the decimal point (3) is not up to 5, it'll be approximated to 0 and added to the second digit (6)
So, we have:
191.5 _
The next digit is calculated as 6 + 0 = 6
Hence, the full approximated number is 191.56
A lender will make an 80% loan-to-value loan on a property that is appraised for $72,250 and sells for $73,500. If the buyer has saved $14,450 for a down payment, how much more (if any) will he need in order to make the down payment required under the terms of this loan?
Answer:
$1,250
Step-by-step explanation:
We are given;
Loan to value ratio;LTV = 80% = 0.8
Appraised value of property = $72,250
Selling value of property = $73,500
Now, the formula for Loan to value ratio is;
LTV = Loan amount/Appraised value of property
0.8 = loan amount/72250
Cross multiply to get;
Loan amount = 0.8 × 72250 = $57,800
Now,we are told that he has saved $14,450.
Thus, total money raised including loan = $57,800 + $14,450 = $72,250
Since the selling value = $73,500, then,
Amount left for him to save in order to make down payment = $73,500 - $72,250 = $1,250

24 - 4 x 2 + 4b = 20 - 16
Answer:
b = -3
Step-by-step explanation:
Solve for b:
4 b - 4 2 + 24 = 20 - 16
-4×2 = -8:
4 b + -8 + 24 = 20 - 16
Grouping like terms, 4 b - 8 + 24 = 4 b + (24 - 8):
4 b + (24 - 8) = 20 - 16
24 - 8 = 16:
4 b + 16 = 20 - 16
20 - 16 = 4:
4 b + 16 = 4
Subtract 16 from both sides:
4 b + (16 - 16) = 4 - 16
16 - 16 = 0:
4 b = 4 - 16
4 - 16 = -12:
4 b = -12
Divide both sides of 4 b = -12 by 4:
(4 b)/4 = (-12)/4
4/4 = 1:
b = (-12)/4
The gcd of -12 and 4 is 4, so (-12)/4 = (4 (-3))/(4×1) = 4/4×-3 = -3:

(b) If the wheel is spun 1,000 times, it is expected about 31 of those times to result in the ball landing in slot 3.
(c) If the wheel is spun 100 times, it is expected about 47 of those times to result in the ball landing in an odd number.
Step-by-step explanation:
We are given that in the game of roulette, a wheel consists of 32 slots numbered 00, 0, 1, 2, . . . , 30.
To play the game, a metal ball is spun around the wheel and is allowed to fall into one of the numbered slots.
(a) The sample space is {00, 0, 1, 2, . . . , 30} which means the metal ball can land on any of these numbers.
(b) As we know that there is an equal probability of the metal ball landing on any of the slots marked in the sample space.
Total number of slots = 32
Number of slots marked with 3 = 1
So, the probability that the metal ball falls into the slot marked 3 is given by = [tex]\frac{1}{32}[/tex] = 0.031 or 3.1%
This means that if the wheel is spun 100 times, it is expected about 3.1 of those times to result in the ball landing in slot 3.
So, if the wheel is spun 1,000 times, it is expected about 31 of those times to result in the ball landing in slot 3 because (0.031 [tex]\times[/tex] 1000) = 31.
(c) As we know that the odd slot in the given sample space is {1, 3, 5,......, 29}.
Total number of slots = 32
Number of odd slots = 15
So, the probability that the metal ball lands in an odd slot is given by = [tex]\frac{15}{32}[/tex] = 0.47 or 47%.
This means that if the wheel is spun 100 times, it is expected about 47 of those times to result in the ball landing in an odd number.

M is the midpoint of line segment AB
Answer:
The coordinates of A would be (-1, 2)
Step-by-step explanation:
In order to find this, use the mid-point formula.
(xA + xB)/2 = xM
In this, the xA is the x value of point A, xB is the x value of point B, and xM is the x value of M. Now we plug in the known information and solve for xA.
(xA + 5)/2 = 2
xA + 5 = 4
xA = -1
Now we can do the same using the midpoint formula and the y values.
(yA + yB)/2 = yM
(yA + 10)/2 = 6
yA + 10 = 12
yA = 2
This gives us the midpoint of (-1, 2)
What is an equation of the line that passes through the point (-2, -3) and is
parallel to the line 5x + 2y = 14?
Answer: 2y + 5x + 16 = 0
Step-by-step explanation:
To solve this you need to understand the principle/ conditions for parallelism and perpendicularity.
for two lines to be parallel to each other, their gradients or slopes (m) must be equal, that is m₁ = m₂
Now from the given equation,
5x + 2y = 14 , we need to rearrange it to conform to the equation of a straight line so that the gradient could be established. ie
y = mx + c where m is the gradient
2y = -5x + 14
y = -5x/2 + 14/2
y = ⁻⁵ˣ/₂ + 7 , therefore , m₁ = ⁻⁵/₂ and m₂ = ⁻⁵/₂ ( parallelism Rule )
The next step is to find the value of C using the coordinate ( -2, -3 )
-3 = ⁻⁵/₂ ˣ ⁻² + C,
-3 = ¹⁰/₂ + C
-3 = 5 + C
C = -8.
Now to find the equation of the line that passed through the coordinate
y = mx + c
y = ⁻⁵ˣ/₂ - 8
2y = -5x - 16
2y + 5x + 16 = 0.
solve 1/2x + 7 = x - 3
Answer: x=20
Step-by-step explanation:
1/2x + 7 =x -3 add 3 to both sides
+3 +3
1/2x + 10 = x Subtract 1/2x from both sides
-1/2x -1/2x
10 = 1/2x
x = 20
Answer:
[tex]x=20[/tex]
Step-by-step explanation:
We can solve for x by simplifying the equation until we have x isolated on one side.
[tex]\frac{1}{2}x + 7 = x-3[/tex]
Subtract 7 from both sides:
[tex]\frac{1}{2}x = x-10[/tex]
Subtract x from both sides:
[tex]-\frac{1}{2}x = -10[/tex]
Multiply both sides by -2:
[tex]x = 20[/tex]

An electronic product takes an average of 4 hours to move through an assembly line. If the standard deviation is 0.5 hours, what is the probability that an item will take between 2.8 and 4.3 hours to move through the assembly line
Answer:
0.7176
Step-by-step explanation:
We solve this question, using z score formula.
Z score formula = (x - μ)/σ
where x is the raw score
μ is the population mean
σ is the population standard deviation.
For z1, where x1 = 2.8, μ = 4, σ = 0.5
z score formula = (2.8 - 4)/0.5
= -2.4
We find the probability of the z score using the z score table.
P(x = 2.8) = P(z = -2.4)
= 0.0081975
For z2, where x2 = 4.3, μ = 4, σ = 0.5
z score formula = (4.3 - 4)/0.5
= 0.3/0.5
= 0.6
We find the probability of the z score using the z score table.
P(x = 4.3) = P(z = 0.6)
= 0.72575
The probability that an item will take between 2.8 and 4.3 hours to move through the assembly line is calculated as:
= 2.8 < x < 4.3
= P(z = 0.6) - P(z = -2.4)
= 0.72575 - 0.0081975
= 0.7175525
Approximately ≈ 0.7176
Therefore, the probability that an item will take between 2.8 and 4.3 hours to move through the assembly line is 0.7176
