Answer:
11.4 metres
Step-by-step explanation:
Use Pythagoras theorem for a right-angled triangle
a^2 + b^2 = c^2
if you cut the rectangle in half, it will become a right angled triangle.
a and b are two sides of the rectangle, while c is the diagonal or hypothenuse
so 9^2 + 7^2 = c^2
81 + 49 = c^2
c^ 2 = 130
square root 130 = c
you should get approximately 11.4 metres
Answer:
$47.41
Step-by-step explanation:
7.75% as a decimal would be 0.0775.
multiply:
0.0775(44)=3.41
add that $44.
$44+$3.41=$47.41
8/8
I added them together since they say " Altogether "
Answer:
4
Step-by-step explanation:
To find the rate of change for the increase (warm up), use the coordinate pair of any two points on the line that slopes upwards in the graph.
Let's use the following:
At 5 mins (x), heart beats (y) is 80 => (5, 80)
At 10 mins (x), heart beats (y) is 100 => (10, 100)
Rate of change = 
Rate of change is 4.
18 is 60% of 30. I know this because 10% of 30 is 3 and 3 * 6 is 18
