Answer:
The difference between the average speed is 12 kilometers per hour, where Serah's train has the greatest speed.Step-by-step explanation:
Givens
Javier's train travels 130 km in 75 minutes.Serah's train travels 377 km from 9:35 to 12:50.The average speed is defined as
[tex]s=\frac{d}{t}[/tex]
To finde Javier's speed, we need to transform 75 minutes into hours, we know that 1 hour is equivalent to 60 minutes.
[tex]h=75min \times \frac{1hr}{60min} =1.25 \ hr[/tex]
Now, we find the average speed
[tex]s_{Javier}=\frac{130km}{1.25hr}=104 \ km/hr[/tex]
Therefore, Javier's train travels 104 kilometers per hour.
On the other hand, Serah's traing travels from 9:35 to 12:50, which is equivalent to 3 hours and 15 minutes, but 15 minutes is equivalent to 0.25, so the total time is 3.25 hours, so the average speed is
[tex]s_{Serah}=\frac{377km}{3.25hr}= 116 \ km/hr[/tex]
So, the difference would be
[tex]116-104=12 \ km/hr[/tex]
Therefore, the difference between the average speed is 12 kilometers per hour, where Serah's train has the greatest speed.
Answer:
12 km/h

Answer:
The value of [tex]x[/tex] :
[tex]x = 16[/tex]
Step-by-step explanation:
-To find the value of x, you need to use [tex]3x + 18[/tex] and [tex]66\textdegree[/tex] written as in equation like this:
[tex]3x + 18 = 66[/tex]
-Then, you solve for it:
[tex]3x + 18 = 66[/tex]
[tex]3x + 18 -18 = 66 -18[/tex]
[tex]3x = 48[/tex]
[tex]\frac{3x}{3} = \frac{48}{3}[/tex]
[tex]x = 16[/tex]
So, therefore the final answer is [tex]x = 16[/tex].

Which expression finds the measure of an angle that is coterminal with a 126° angle?
Answer:
Therefore the expression that finds the coterminal angles is:
[tex]coterminal = 126\º \pm 360[/tex]
Step-by-step explanation:
Coterminal angles are angles that finish at the same line. Therefore in order to find the coterminal angles with 126º we need to add or subtract a angle of 360º. So the expressions are:
coterminal angle = 126º + 360º = 486º
coterminal angle = 126º - 360º = -234º
Therefore the expression that finds the coterminal angles is:
[tex]coterminal = 126\º \pm 360[/tex]
Answer:
126° + (720n)°, for any integer n or D on edge :)

Answer:
With that amount of butter she can make 26 pies.
For each pie she spends $1.13625 of butter.
Step-by-step explanation:
We first need to convert the total amount of butter she has from pounds to cups, to do that we need to multiply by 2, since for each pound she has 2 cups of butter, therefore:
butter in cups = 10*2 = 20 cups
Since each pie requires 3/4 cups of butter in order to calculate the number of pies she can make we need to divide the total amount of butter she has by the amount required for each pie. We have:
number of pies = total butter in cups / butter for one pie
number of pies = 20 / (3/4) = 20*(4/3) = 80/3 = 26.667
Since she can't make 0.66 pies, we will need to take only the integer part in consideration, therefore she can make 26 pies.
In order to know the cost for each pie we first need to know the cost for each pound of butter, to calculate that we take the total amount paid by her and divide it by the amount of butter she got.
price of butter per pound = 30.3/10 = 3.03
So each pound of butter costs $3.03 and is equivalent to 2 cups, we can make a rule of three to find the cost for each pie as shown below:
2 cups -> $3.03
3/4 cups -> $x
2/(3/4) = 3.03/x
2*(4/3) = 3.03/x
8/3 = 3.03/x
8x = 9.09
x = 9.09/8 = $1.13625
For each pie she spends $1.13625 of butter.

Which of the following tables represents the equation y=2x-1
Answer:
There are no tables, but... I made a quick graph.
Step-by-step explanation:
y=2x-1 means that you start at (0,-1), one down from the origin (0,0). From there, you go up 2 and right one (1, 2), as well as down 2 and left 1 (-1, -2), since the slope is 2 (or [tex]\frac{2}{1\\}[/tex]). The lines continues in both directions, of course.
The table for the equation is y = 2x - 1
x y
0 -1
1 1
2 3
How to determine the tableTo determine which table represents the equation y = 2x - 1, we substitute the values of x into the equation and check if the resulting y values match those given in the table.
Substitute the values 0, 1, and 2 into the equation y = 2x - 1 and calculate the corresponding y-values:
For x = 0:
y = 2(0) - 1
y = 0 - 1
y = -1
For x = 1:
y = 2(1) - 1
y = 2 - 1
y = 1
For x = 2:
y = 2(2) - 1
y = 4 - 1
y = 3
The corresponding y-values for x = 0, 1, and 2 are -1, 1, and 3, respectively.

Step-by-step explanation:
The volume of a cylinder is [tex]\pi r^2*h[/tex]
V = 48π
AB = 12π
So since the area of the base is 12π, you can find the height by simply dividing 48π by it.

Heng Roth invests $9000 at 2%
per annum compound interest daily. What
is his amount at the end of the third day?
(1 year =365 days)
Answer:
After three days Heng will have 9000.15 in his account.
Step-by-step explanation:
In order to solve this problem, we must apply the correct formula, which is given below:
[tex]M = C*(1 + r/n)^{n*t}[/tex]
Where M is the final amount, C is the money invested, r is the annual interest rate, n is the number of times the money gets compounded in a year and t is the time elapsed. Since in this account the money is compounded daily, it means that for each year it gets compounded 365 times, therefore n = 365. The ammount will be compounded for 3 days, therefore we must convert this value to years in order to apply it in the "t" variable, we do that by dividing it by 365. With this knowledge we can solve the problem as shown below:
[tex]M = 9000*(1 + \frac{0.002}{365})^{365*\frac{3}{365}[/tex]
[tex]M = 9000*(1.000005479)^{3}\\M = 9000.15\\[/tex]
After three days Heng will have 9000.15 in his account.
A rectangular prism has a base with a length of 25, a width of 9, and a height of 12. A second prism has a square base with a side of 15. If the volumes of the two prisms are equal, what is the height of the second prism?
picture is here
Answer:
Step-by-step explanation:
the volume of a rectangle is length x width x height, so the volume of the first rectangle is 2700.
the square has a length and width of 15 with a missing height. because they have the same volume, you can plug in the length and width of the square with the volume of the prism to find the height
v = length x width x height
2700 = (15)(15)h
2700/225 = h
the height is 12

A soccer team orders 15 wooden pedestals to mount their brass trophies on. The design of each pedestal is shown below. The team is charged $0.12 per cubic inch of wood. What is the total cost of the order, rounded to the nearest dollar?
Answer:
$1193
Step-by-step explanation:
First we need to find the volume of one pedestal, that has a cylindrical part and a cubic part.
The volume of the cylindrical part is:
V1 = pi * r^2 * h
The radius is half the diameter, so r = 8/2 = 4 in. So the volume is:
V1 = pi * 4^2 * 3 = 48pi in3
The volume of the cubic part is:
V2 = side^3 = 8^3 = 512 in3
So the total volume of the pedestal is:
V = V1 + V2 = 512 + 48pi in3
If we want 15 pedestals, we have a total volume of:
15 * V = 15 * (512 + 48pi) = 9941.9467 in3
As each cubic inch costs $0.12, we just need to multiply the volume by the price to find the total cost:
Cost = 9941.9467 * 0.12 = $1193.03
Rounding to the nearest dollar, we have a cost of $1193

ONLY COMPLETE QUESTION 1
Answer: 1/4 full.
Step-by-step explanation:
The question is asking for how much gas will be left in the tank after 2/3 of the gas in the tank is used.
There is currently 3/4 of the tank remaining.
To find 2/3 of 3/4, you can multiply the fractions together.
Do this by multiplying both numerators and both denominators:
[tex]\frac{2}{3} *\frac{3}{4} = \frac{2*3}{3*4} = \frac{6}{12}[/tex]
Then, subtract 6/12 from 3/4. You can do this by simplifying the first fraction to 2/4 (divide both the numerator and denominator by 3).
3/4 - 2/4 = 1/4
There will be 1/4 of the tank left.
Answer:
1/4
Step-by-step explanation:
We have 3/4 of a tank
We will use 2/3 of the gas in the tank
See the diagram That will leave us 1/4
Mathmatically
3/4*2/3 = 2/4 =1/2 this is the amount that is used
Subtract this from the amount in the tank
3/4 -1/2
3/4 -2/4 = 1/4
This is the amount that is left in the tank
2(2x + 7) - 7(x+1)= 28
2(2x+7)-7(x+1)=28
4x+14-7x-7=28
4x-7x=28+7-14

Last question: What equation represents three less than five times a number is twelve?
A. 3 - 5x = 12
B. 5x - 3 = 12
C. 5(3 - x) = 12
D. 5(x - 3) = 12
Answer:
B, 5x - 3 = 12
Step-by-step explanation:
3 less means subtracting, it's going to be -3.
It says 3 less than five times a number, meaning we don't know the number, so we can put it as x.
3 less means your subtracting from something, which would make it 5x - 3.
Finally, they state that it equals 12, making the equation 5x - 3 = 12.
