1) Formula: area = height * base / 2
2) Call x the height:
height = x
base = 2x
3) State the equation:
(x)(2x) = 49 in^2
4) Solve the equation:
2x^2 = 49 in^s
x^2 = (49/2) in^2
x = √(49/2) in
x = 7√2 / 2 in = 3.5 √2 in
5) Solution:
height = 3.5 √2 in and base = 7√2 in
6) Verification: area = (7√2 in) (3.5√2 in) = 49 in^2
Answer: height = 3.5√2 in and base = 7√2 in.
Answer:
Initial height or what the ball was originally bounced from a height of 9 feet
Step-by-step explanation:
9 represents the height that the ball was originally bounced from.
If you plug in 0 for
into
, you get:
.
9 feet is the initial height since that is what happens at time zero.
Answer:
Approximately 45% students signed up for neither canoeing or trekking.
Step-by-step explanation:
First we subtract the number of the students who signed up from the number of the total students to find the number of the students who did not signed up for either.
But there are 13 students who signed up canoeing and also for trekking.
Hence the number of students they signed up for activity is
72 + 23 - 13 = 82
And the number of students they not signed up for any activity is
150 - 82 = 68
so 68 students signed up neither for trekking nor canoeing. The percentage of those students are :
× 100 = 45.3333%
Approximately 45% students signed up for neither canoeing or trekking.
