Answer:
Below.
Step-by-step explanation:
The center is at (8, 4) and the radius = √11.
√11 = 3.317 to the nearest thousandth.
Answer:
after 1.25 hours
Step-by-step explanation:
1. make 130 your y value
130 = 220 - 72x
2. subtract 220 from both sides
-90 = -72x
3. divide by -72 on both sides
1.25 = x

a) Let,
First odd number = 5
Second consecutive odd number = 7
Sum = 5 + 7 = 12. Which is divisible by 4
b) Let the numbers be same as above
(5)² + (7)²
25 + 49
74. Which is not divisible by 4
10) Maisy is wrong because 2 has no common factor except 1 and 2. And we know that 2 is an even number and it is also a prime number
11)
a) Let,
First integer = 5
Second integer = 7
Sum = 5 + 7 = 12.
Since the sum is even but the integers are odd.
b) Let,
Integer = 8
(8)² = 64. which is divisible by 4 and 8 is also divisible by 4
12)
Let,
a = -8
b = 8
a² = (-8)² = 64
b² = (8)² = 64
a² = b²
But, a ≠ b
Answer:
- w = 8
- x = 8√2
- y = 8√2
- z = 16
Step-by-step explanation:
A 45-45-90 right triangle is isosceles. That means both legs are the same length, and its hypotenuse is √2 times the leg length. You can figure these facts using trigonometry or the Pythagorean theorem, or you can rely on your memory of them.
w = 8 . . . . . . . . . . . same as the leg length shown
x = y = 8√2 . . . . . hypotenuse of smaller triangle; both legs are the same
z = (8√2)√2 = 16 . . . . hypotenuse of larger triangle
