Answer:
The lengths 7, 40 and 41 cannot be sides of a right triangle. The lengths 12, 16, and 20 can be sides of a right triangle.
Step-by-step explanation:
You can test this by using the Pythagorean theorem, which states a^2+b^2=c^2
with 7,40 and 41
7^2+40^2 does not equal to 41^2
but with 12,16, and 20
12^2+16^2=20^2
therefore, the last statement is correct.
Sub y=0 into 3y=2x+6
3(0)=2x+6
-2x=6
x=-3
Ans is B.
Sub x=0 into -2y=4x+8
-2y=4(0)+8
y= -4
Ans is B.
Answer:
A =78.5
Step-by-step explanation:
We need the radius to find the area of a circle
r = d/2 = 10/2 =5
The area of a circle is given by
A = pi r^2
A = 3.14 (5)^2
A =3.14 (25)
A =78.5
A quarter of an hour is 15 minutes, so a quarter past 7 is 7+15 mins. This gives you:
7:15
