(8) 216 yd³

Step-by-step explanation:

Formulas

Volume of prism

= base × height/length

Area of parallelogram

= base × height

Area of trapezium

= (upper base + lower base) × height ÷ 2

(7)

Area of the base = 19×6

= 114 in²

Length = 13 in

Volume = 144×13

= 1482 in³

(8)

Area of the base = (11+7)×12÷2

= 108 yd²

Length = 2 yd

Volume = 108×2

= 216 yd³

Nolan rides his bike 63 miles in 270 minutes. What is his average speed in miles per hour?

Karolina [17]

270 minutes = 4,5 hours = 4 hours and 30 minutes
60 minutes = 1 hour

63 miles per 270 minutes
x miles per 1 hour = 60 minutes

$\dfrac{63[miles]}{x[miles]} = \dfrac{270[minutes]}{60[minutes]}$

$63 \cdot 60 = 270x$
$3780 = 270x\quad |:270$
$x=14[miles]$

His average speed is 14 miles per hour.
