Two trains leave the station at the same time, one heading west and the other east. The westbound train travels 18 miles per hour slower than the eastbound train. If the two trains are 300 miles apart after 2 hours, what is the rate of the westbound train? Do not do any rounding.
Answer:
66 mph
Step-by-step explanation:
w = e - 18
2w + 2e = 300
2 (e - 18) + 2e = 300
2e - 36 + 2e = 300
4e - 36 = 300
4e = 300 + 36 = 336
e = 84 mph
w = 66 mph
The westbound train is travelling at 66 mph

a car traveling 1000 miles in 2 hours has a unit rate of *blank* miles per hour
25
50
200
( ill give brainly to whoever answer first w an explanation)
Answer:
50
Step-by-step explanation:
Looks like a typo in the question
To get the unit rate, divide the miles by the hours
Unit rates
1000 miles in 2 hours = 1000/2 = 500
I'm guessing you meant 100 miles not 1000 miles
100 miles in 2 hours = 100/2 = 50

a b and c are positive integers a:b
=3:8 and b:c=6:11
Answer:
a= 18; b= 48; c= 88. Please note that even half these value work (9, 24, 44) or any multiple of these (9k, 24k, 44k, with k a positive integer)
Step-by-step explanation:
Let's go easy, and pick b to be 6x8, to make things easy for us. Maybe even 6x4 could work, 12x8 will totally work, but this is the simplest choice.
Now on the first proportion [tex]a:48=3:8 \rightarrow 8a = 48\times3 \rightarrow a = 18[/tex]
From the second proportion [tex]48:c=6:11 \rightarrow 6c = 48\times 11 \rightarrow c = 88[/tex]
Help with my work mane please im bwgging you
Answer:
A) 1, 4, 5, 9, 14, 23, 37
B) 2, 4, 6, 10, 16, 26, 42
Step-by-step explanation:
1. The Fibonacci sequence states that each number is the sum of the two numbers before it.
For example, if we have the first two numbers of a sequence as 5 then 6, the next term would be 11.2. Given the information above, let's solve the question.
-> A: 9 + 14 = 23, 14 + 23 = 37
The next two terms for sequence A are 23 then 37-> B: 10 + 16 = 26, 16 + 26 = 42
The next two terms for sequence B are 26 then 42Therefore, the answer is:
A) 1, 4, 5, 9, 14, 23, 37
B) 2, 4, 6, 10, 16, 26, 42
x/2-1=3 what is X PLEASE HELPPPPPPPPPPP
x / 2 - 1 = 3
Add 1 to both sides.
x / 2 = 4
Multiply both sides by 2.
x = 8
Now lets put in 8 for x in our original equation:
8 / 2 - 1 = 3
4 - 1 = 3
3 = 3
This is correct, therefore we know x = 8.

mark owes his sister $15.he earned $20 for mowing the grass. he gave 1/5 of his warning to a local charity and then paid his sister. does mark have enough to repay his sister the full amount?
Answer:
Yes, with some change to spare.
Step-by-step explanation:
He has 20$. Take 1/5 of it, it's 4$ (because 4x5 = 20), so he will be left with 16$. He owes less than this, 15$, so he can repay his debt in full and have still 1$ left.

A trigonometric graph has the equation y=2cos2∅. State the amplitude of this graph?
Answer:
amplitude = 2
Step-by-step explanation:
Given
y = a cosbx
amplitude = | a | , period = [tex]\frac{2\pi }{b}[/tex]
y = 2cos2∅
with amplitude = | 2 | = 2
Answer:
[tex]\displaystyle 2[/tex]
Step-by-step explanation:
[tex]\displaystyle y = Acos(Bx - C) + D \\ \\ Vertical\:Shift \hookrightarrow D \\ Horisontal\:[Phase]\:Shift \hookrightarrow \frac{C}{B} \\ Wavelength\:[Period] \hookrightarrow \frac{2}{B}\pi \\ Amplitude \hookrightarrow |A|[/tex]
With the above information, you should now tell what the amplitude value is.

One angle of a right triangle measures 60°. What is the measure of the other acute angle?
Answer:
30°
Step-by-step explanation:
as sum of angles = 180°
so 180° -(90° + 60°) = 30°
[tex]\qquad[/tex] ☀️It's given,One angle of a right triangle measures 60°.
Let, the other acute angle will be x.[tex]\qquad[/tex] According to the question :-
[tex]\qquad \longrightarrow {\purple {\underline{\underline{\pmb{\sf{ Sum_{(All \:angles) }= 180°}}}}}}[/tex]
[tex]\qquad \pmb{\sf\longrightarrow 60° + 90° + x = 180°}[/tex]
[tex]\qquad \pmb{\sf\longrightarrow 150° + x = 180°}[/tex]
[tex]\qquad \pmb{\sf\longrightarrow x = 180° - 150°}[/tex]
[tex]\qquad \longrightarrow {\pink{\underline{\underline{\pmb{\sf{ x= 30°}}}}}}[/tex]
Therefore–
The other acute angle is 30°.▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬

A gallon is 128oz. An airplane can carry 1,445 gallons of fuel. Write the number of ounces of fuel the plane can carry.
Step-by-step explanation:
one gallon is 128oz.
1445 gallons are how many Oz?
that applies the same principle as every-day situations like "every guest will eat 2 dumplings. 12 guests are coming, so how many dumplings do I have to prepare ?"
or totally simple : "every child will get one gift. 4 children are coming, so how many gift do I have to prepare ?"
it all works with multiplication. it is the ultimate application for multiplication.
that is why we use "times" in normal language as in mathematical terms. like "it takes 3 screws to mount a leg to a table. and the table needs 4 legs. how many times do I need to fasten a screw to finish one table ?" well, 4 times 3 or 4×3 = 12 times.
and so, the answer to the original question is then I need to take the amount of one gallon 1445 times.
128 × 1445 = 184,960oz

why does the formula for area of a circle make sense
Answer:
Step-by-step explanation:
The usual definition of pi is the ratio of the circumference of a circle to its diameter, so that the circumference of a circle is pi times the diameter, or 2 pi times the radius. The animation above shows that a circle can be cut and rearranged to closely resemble a parallelogram (with height r and base pi times r) of area pi times the square of the radius. By dividing the circle into more than eight slices, the approximation obtained in this manner would be even better. By dividing the circle into more and more slices, the approximating parallelograms approximate the area of the circle arbitrarily close. This give a geometric justification that the area of a circle really is "pi r squared".
