Answer:
using pythagoras theorem
H^2=P^2+B^2
here h=MN ,opposite(P) be 15 and adjacent(B) be 16
(MN)2=15^2+16^2
(MN)^2=225+256
MN=
MN=21.93
after rounding off MN=21.9
Step-by-step explanation:
Answer:

Step-by-step explanation:
Because if one out of four is read then there is four marbles.
The answer is D. decimal number of percentage
Answer:
5x - 5
Step-by-step explanation:
To find the missing side, add the two sides together and subtract them from the perimeter.
side 1 + side 2
3x + 2 + 8x + 7
combine like terms
11x + 9
Subtract from the perimeter
16x + 4 - (11x + 9)
rewrite as an addition problem, so you need to change the signs inside the parentheses.
16x + 4 + (-11x -9)
Now combine like terms
5x - 5
If you graph the equation, you will see the vertex is (0.75, 6.125), the y-intercept is (0, 5) and the x-intercept is (2.5, 0). These key points answer the questions below.
A. It starts at 5 feet (y-intercept)
B. The max height is 6.125 feet (vertex)
C. Cannot be found (the graph is about height and distance, not time)
D. If lands 2.5 feet from the start (x-intercept)
