15h > = 200
h > 200/15
h > 13 1/3.......1/3(60) = 60/3 = 20
13 hrs and 20 minutes is correct...nice job :)
Answer:
.7
Step-by-step explanation:
As a decimal it would be .7, easy way to do it is 7/10 is 70%, change the % to a . and move it to the left twice, leaving you with .70, 0's are place holders, and you dont have to write them if there is nothing behind it, leaving you with .7
Hope this helped, Brainliest?
Plug in the point for each equation:
x=1/4y + a
(1)=1/4(2) + a
1=1/2+a
1/2=a
y=1/4x+b
2=1/4(1) +b
b= 7/4
Solve a+b:
a+b=?
(2/4)+(7/4)= 9/4= 2.25
Answer:
Step-by-step explanation:
Miles per hour is a speed and we usually just hear the number of how fast a car or a rocket or meteor is going. We look at our speedometer in the car and see how fast we're driving, 35mph or 73mph
But it is literally a formula. Miles on top and hours on the bottom, like a fraction. If the numbers you're given are in miles and in hours, your can just fill in the numbers and simplify.
Your numbers are also fractions, so it looks a little scary, but no worries, you can simplify it.
You have 1/2 on top and 1/16 on the bottom. A fraction bar is just a division sign, we're going to divide 1/2 ÷ 1/16 We do this by using the rule:
Keep Change Flip
1/2 Keep
___ Change
1/16 Flip
Keep the 1/2
Change ÷ to *
Flip the 1/16
So it becomes 1/2* 16/1
1/2 * 16 is 8
8 miles per hour is your answer.
If fractions are too terrifying, you could just change 1/2 to .5 and
change 1/16 to .0625
.5 ÷ .0625= 8
Answer: 8mph
