This is another one for my "impossible math question" file. All of the answer choices are wrong. (None applies.)
According to the problem statement, the length you have marked "x" in the diagram is 15 inches. If the side length of one of the pavers is "s", then the Pythagorean theorem tells us
s² + (2s)² = 15²
5s² = 225
s² = 225/5 = 45 . . . . . . the area of one square is 45 in² (not 225 in²)
Then
s = √45 = 3√5 . . . . . . . the length of one side is not 5√3
so the perimeter is
p = 4s = 4·3√5 in = 12√5 in ≈ 26.83 in . . . . not 75 inches.
The area of the 6-block L-shaped path is
total area = 6s² = 6·45 in² = 270 in² . . . . not 450 in²
And the total perimeter is 14 sides, so is
total perimeter = 14s = 14·3√5 in = 42√5 in . . . . not 60√3 in

In cases like this where the answer key is incorrect, you might try asking your teacher show the class how to work the problem.
Answer:
You are correct
(-6, 7)
(-1, 3)
(3, 3)
Step-by-step explanation:
relative maximum is when a function goes from increasing to decreasing.
So, you have correctly marked the relative maximum points of this graph, great job :)
Answer:
35 degrees
Step-by-step explanation:
180 - 110 = 70 (TUW and UWT together)
70 / 2 = 35 (UWT)
Since the other part is congruent, we can assume it is also 35.
Step-by-step explanation:
to compare day 1 with day 2 :
100% = 8
1% = 100%/100
25% = 25×1% = 100% × 25/100 = 8 × 1/4 = 2
so, on day 2 he walks 8+2 = 10 laps.
on day 3 he walks then 10-1 = 9 laps.
so, now, to calculate the % decrease compared to day 2
100% = 10
1% = 100%/100 = 0.1
how many % is represented by this 1 lap he was walking less ?
1 / 1% = 1 / 0.1 = 10%
so he had a 10% decrease from day 2 to day 3.
One bits can code 0 or 1, which was 2 possibilities. Every bits can code
possibilities with x is number of bits. The possibilities that need to be code is the coordinate. The possibilities should be: 96 x 96 = 9216 possibilities.
The easy way to find the bits is by dividing the possibilities with 64 and every 64 is 5 bits(
=64) then 2 for 1 bits until it <1. Then the answer would be: 9216/64= 144/64= 2.25/ 2= 1.125/2= 0.5625
The number can be divided by 64 two times and divided by 2 two times, make it 10+2 bits. = 12 bits
