Answer:
Step-by-step explanation:
We can solve this question using proportion
Perimeter of the square/Time is takes to unlock
We are told in the question that:
The cellphone unlocks when the perimeter reaches 32 centimeters, taking a total of 2.5 seconds.
Hence, the perimeter of the square after 1.5 seconds is:.x = unknown
32/2.5 = x/1.5
Cross Multiply
2.5x = 32 × 1.5
x = 32 × 1.5/2.5
x = 19.2 centimeters
The y-intercept is (0,2)… Hope this helps..
156°
D is a 24° angle, and is placed in a 90° angle, so 90-24=66
C is a right angle, so 90+66=156°
Hope this helped!
Hi there! The word "difference" means to subtract. -2 - -6=4. Therefore, it would be the last one.
