Answer: The value of x is 13 cm.
Explanation:
It is given that the length and width of the rectangle are 12 cm and 9 cm.
Use pythagoras to find the value of the diagonal.
It is given that the diagonal is labeled as 2x-11.
Divide both side by 2.
Therefore, x = 13cm.
√5 is √5!!!
It's irrational number.
2 < √5 < 3 because 2² = 4 < 5 < 3² = 9
√5 ≈ 2.236
Answer:
A=12
B=54
C=18
Step-by-step explanation:
A=first
B=second
C=third
A+B+C=84
B=3C
A=C-6
C-6+3C+C=84
5C-6=84
5C=90
C=18
A=C-6
=(18)-6
=12
B=3C
=3(18)
=54
Answer:
After 4 seconds, the ball is at 229 ft
Step-by-step explanation:
Here, we want to get the height of the ball at 4 seconds
What we have to do here is to substitute the value of t for 4 seconds in the equation
We have;
h = -16(4^2) + 121(4) + 1
h = -256 + 484 + 1
h = 229 ft
The answer is 3/25 or .12. Use the formula 1/2bh to find the area of triangles.
1/2(.4)(.6)
1/2(.24)
.12
hope that helps :)
