8 in 3

27 in

64 in

Step-by-step explanation:

1 in because 1^3 is 1

4 in 3 because 4^3 is 64 ( 4 x 4 = 16 x 4 = 64)

8 in 3 because 8^3 is 512 ( 8 x 8 = 64 x 8 = 512)

27 in because 3^3 is 27 ( 3 x 3 = 9 x 3 = 27)

64 in because 4^3 is 64 ( 4 x 4 = 16 x 4 = 64)

X2+5x=3x+11 and solve by completing the square

Butoxors [25]

$x^2+5x=3x+11\\
x^2+2x-11=0\\
x^2+2x+1-12=0\\
(x+1)^2=12\\
x+1=\sqrt{12} \vee x+1=-\sqrt{12}\\
x=-1+2\sqrt3 \vee x=-1-2\sqrt3$

A school bus during morning pickups to calculate its average speed between 2.8 km and 4.2 km.

kifflom [539]

<u>Answer: </u>

Option (c)

The average speed between 2.8 km and 4.2 km is 42 km/h

<u>Explanation:</u>

Given, the distance between 2.8 km and 4.2 km is 4.2 - 2.8 = 1.4 km

Time (in hours) between 2.8 km and 4.2 km

= 0.084 – 0.051

= 0.033 hr

Speed = $\frac{Distance}{Time}$

Speed = $\frac{1.4}{0.033}$

Speed = 42.4 km/hr = 42 km/h (rounded to nearest)

Therefore, the average speed between 2.8 km and 4.2 km is 42 km/hr

Hence, Option (C) is correct
