Answer:
[tex]39.29\ \text{km/h}[/tex]
Step-by-step explanation:
s = Speed of the train
m = Money spent on maintanence
[tex]s\propto m^{\dfrac{1}{3}}[/tex]
Let k be the constant of proportionality so
[tex]s=k (m)^{\dfrac{1}{3}}[/tex]
Now a case is given where 25 km/hr is possible on a stretch for which 450,000 is spent so
s = 25
m = 450000
[tex]s=k (m)^{\dfrac{1}{3}}\\\Rightarrow k=\dfrac{s}{m^{\dfrac{1}{3}}}\\\Rightarrow k=\dfrac{25}{450000^{\dfrac{1}{3}}}\\\Rightarrow k=0.326[/tex]
Now when m = 1750000
[tex]s=k (m)^{\dfrac{1}{3}}\\\Rightarrow s=0.326\times 1750000^{\dfrac{1}{3}}\\\Rightarrow s=39.29\ \text{km/h}[/tex]
The maximum speed of the train would be [tex]39.29\ \text{km/h}[/tex].

Answer:
1) 4 ft
2) Length =69
Width=64
Step-by-step explanation:
1) 2x-2+2x-2+x-2+x-2=x+x-1+x-1
6x-8=3x-2
6x-3x=-2+8
3x=6
x=2
plugging it back in, we get for the triangle
2+2-1+2-1=4 (same answer for the rectangle, although it would have a width of zero)
2) w+w+w+5+w+5=266
4w+10=266
4w=266-10
4w=256
w=64
l=64+5=69

What is the equation of the line that passes through the point (2,0) and has a slope of 5/2 ?
Answer:
y = [tex]\frac{5}{2}[/tex] x - 5
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = [tex]\frac{5}{2}[/tex] , thus
y = [tex]\frac{5}{2}[/tex] x + c ← is the partial equation
To find c substitute (2, 0) into the partial equation
0 = 5 + c ⇒ c = 0 - 5
y = [tex]\frac{5}{2}[/tex] x - 5 ← equation of line
The equation of the line is the way of represent the line by the given point in the coordinate plane and the its slope.. Thus the equation of the line with point (2,0) and slope 5/2 is,
[tex]y=\dfrac{5}{2} x-2[/tex]
Given information;
The point of the line through which the line passes are (2,0).
The slope of the line is 5/2.
Equation of the lineThe equation of the line is the way of represent the line by the given point in the coordinate plane and the its slope.
The standard form of the equation of the line for point and slope can be given as,
[tex](y-y_1)=m(x-x_1)[/tex]
Put the values,
[tex](y-0)=\dfrac{5}{2} (x-2)[/tex]
Solve it further;
[tex]y=\dfrac{5}{2} x-2[/tex]
Thus the equation of the line with point (2,0) and slope 5/2 is,
[tex]y=\dfrac{5}{2} x-2[/tex]

1. A basketball player made 12 out of 15 free throws she attempted. She wants to know how many consecutive free throws she would have to make to raise the percent of successful free throws to 85%. (a) Write an equation to represent this situation. (b) Solve the equation. How many consecutive free throws would she have to make to raise her percent to 85%?
Answer:
So 12 of 15 free throws is 80% so she would have to make at least 13 of 15 free throws to at least get over 85% cause 13 of 15 is 86.6% repeated

How many positive divisors does the number 24 have?
With a beginning balance of $1200 and no additional charges during the next three months, you will just pay the minimum payment each month for the next three months. The APR is 24.99% and the minimum payment each month is 3% of the balance.
Here is the complete question.
With a beginning balance of $1200 and no additional charges during the next three months, you will just pay the minimum payment each month for the next three months. The APR is 24.99% and the minimum payment each month is 3% of the balance. Determine the finance charge, new balance, and minimum payment required for each of the next three months, and the starting balance for month 4 in the table below.
a) What is the total of minimum payments?
b) What is the total sum of the finance charges?
c) How much does the starting balance decrease after these three payments?
d)The total of your finance charges is what percent of our total payments?
Answer:
Step-by-step explanation:
Month Beginning Finance New Minimum
Balance Charge Balance Payment
1 $ 1200 24.99 1224.99 36.75
2 1188.24 24.75 1212.99 36.39
3 1176.60 24.50 1201.10 36.03
4 1165.07 24.26 1189.33 35.68
a.
The total minimum payments for 3 months = 36.75 + 36.39 + 36.03
The total minimum payments for 3 months = $ 109.17
b.
Total finance charges for 3 months = 24.99 + 24.75 + 24.50
Total finance charges for 3 months = $ 74.24
c. The starting balance decrease from 1200 to 1165.07, this implies that there is a reduction of $ 34.93
d. The total of finance charges = 74.24×(100/109.17)
The total of finance charges = 68% of total payments.

Which point lies on the graph of the finite sequence shown? 5,-1,6, 0, 7, 1,8 O (-1,2) (0,5) (5, 1) (6, 1)
Answer: (6,1)
Step-by-step explanation:
A point which lies on the graph of the finite sequence is,
⇒ (6, 1)
Given that;
A sequence is,
⇒ 5, -1, 6, 0, 7, 1, 8
Now, You have to look at the first coordinate (x -Axis) then go over that many times in the sequence and if that number is matched with the y-axis, then you got it.
Hence, Look at your numbers then go to (6, 1) go over 6 and if you land on 1 then that's the answer.

Mary-Ann has $28, which is 2 1 3 as much money as Lola has. How much money does Lola have? find the number
Answer:
Lola has $12
Step-by-step explanation:
To find how much money Lola has, we need to divide $28 by 2 1/3:
28 ÷ 2[tex]\frac{1}{3}[/tex] = [tex]\frac{28}{1}[/tex] × [tex]\frac{3}{7}[/tex] = [tex]\frac{12}{1}[/tex] = 12
Hope this helps! :)
Answer:
$12
Step-by-step explanation:
Lola has x.
Mary-Ann has 2 1/3 times what Lola has. Mary-Ann has $28
2 1/3 * x = 28
Change 2 1/3 into a fraction.
(7/3)x = 28
Multiply both sides by the reciprocal of 7/3 which is 3/7.
(3/7) * (7/3)x = (3/7) * 28
x = 12
Answer: Lola has $12.

24. Seven tenths of a number plus 14 is less than forty-nine.
Answer:
50. ☺️☺️
Step-by-step explanation:
I'm going to assume you need this inequality solved.
First, write it as numbers, not words.
7/10n + 14 < 49
where "n" is the unknown number.
Second, if I were you, I'd change that fraction into a decimal, as it'll make life easier later on.
7/10 = 0.7
Now, solve it like you would any other equation.
0.7n + 14 < 49
0.7n +14 - 14 < 49 - 14
0.7n < 35
0.7n ÷ 0.7 < 35 ÷ 0.7
n < 50
The answer is n < 50
Answer: 50
Step-by-step explanation:
49 - 14 = 35
35/7 = 5
10 x 5 = 50
Since, 35 is Seven tenths of a number, One tenth is 5 and there are ten tenths, One tenth which is 5 times ten since there are ten tenths equals to 50 (5 x 10 = 50).
Fredrick manages a band and sing leads vocal the band charges $700 per concert Frederick receives 175 of that money and he shares the rest equally among the other five members of the band how much money does each of the five band members receive per concert
Answer:
Each will receive $105Step-by-step explanation:
Step one:
given data
we are told that the total amount made is $700
If Frederick receives $175 from the amount made the balance left to share is
=700-175
=$525
Step two:
Hence the five band members will share $525
each of them will receive
=525/5
=$105
a team of divers assembles at an elevation of -10 ft relative to the surface of the water. Then the team dives at a rate of the water. Then the team dives at a rate of -50ft/min. Write a rule that represents the teams depth d as a function of time t. What is the team's depth after 3 minutes?
Answer: The team will be 160 feet below sea level after 3 minutes.
Step-by-step explanation:
If the team is at -10 ft relative to sea level then it means that they are 10 feet below sea level, and if they also going -50 ft per minute, it also means that they are still going below sea level.
The rule will be, d= -50t -10
If t is the time, input 3 minutes into the equation for t and solve for d to find their depth.
d= -50(3) - 10
d= -150 - 10
d= -160
