A bus travels at a speed of 40 miles per hour and reaches Hogville in 40 minutes. If a cab takes 35 minutes to reach the same spot, determine the speed at which it traveled.
Answer:
45.7miles per hour
Step-by-step explanation:
40mins = 2/3 hour
the bus travelled (2/3 x 40) miles = 80/3 miles
the cab took 35 mins (which is 7/12 hour) so it's speed is (80/3)/(7/12) miles/hour = 45.714 miles/hour (5 s.f.)

Think about it as money
If you owe me $10, this is shown as -10
Now if I give you back 2 dollars (+2), How much money do I still owe you.
The equation is -10+2
I still owe you 8 dollars which is portrayed as -8
Hope this helps :)

Jason invests money in an account paying simple interest. He invests $160 and no money is added or removed from the investment. After one year, he has $164.80. What is the simple percent interest per year?
Answer:
The answer is 3%
Step-by-step explanation:
1.) $160 divided by $164.80 = 1.03
2.) 1.03 x 100 = 103
3.) 103 - 100 = 3
4.) 164.80 - 160 = 4.80
5.) 4.80 divided by 160 = 0.03
6.) 0.03 x 100 = 3%

move constant to the right and change its sign.
= -6x = 1-5
calculate
= -6x = -4
divide both sides of the equation by -6
= -6x/6 = -4/-6

What is the slope-intercept equation for the line below?
A) y = 5/4x - 4
B) y = 4/5x - 4
C) y = -4/5x - 4
D) y = -5/4x - 4
Answer:
A) y = 5/4x - 4Step-by-step explanation:
Slope-intercept formula
y = mx + b, where m = slope, b = y-interceptSlope formula
m = (y2 - y1)/(x2 - x1)Given points (on the graph)
(0, -4) and (4, 1)Slope is:
m = (1 - (-4))/(4 - 0) = 5/4y-intercept is
-4 as per the first pointSo the line is:
y = 5/4x - 4Correct answer option is: A) y = 5/4x - 4

can i get some help with geometry
Answer:
first you need to make that into an equation here i think your equation that will help you on that question is 46°+63°=X
Step-by-step explanation:
K-is (4°k+5°y)+(4°k+10°y)=118°
and then what ever you get out of the K's and Y's you will divide that number by 118 and that is the value of K
and this is my opinion

how coordinates change when we add or subtract outside the function?
Answer:
if c is positive, the graph is shifted up. If c is negative, the graph is shifted down. Informally: Adding a positive number after the x outside the parentheses shifts the graph up, adding a negative (or subtracting) shifts the graph down.
