jada can write 3 1/4 pages in 8 minutes. At this rate, how many pages could jada write in 24 minutes?

makkiz [27]

Answer:

9 3/4 pages = x

Step-by-step explanation:

$\frac{pages}{minutes} = \frac{pages}{minutes}$ change 3 1/4 to a decimal

$\frac{3.25}{8} = \frac{x}{24}$

$3.25(24) = 8x$

$78 = 8x$

$\frac{78}{8} = x$

$9.75 = x$

$9\frac{3}{4} =x$

working with the fraction

3 1/4 /8 = x/ 24

3 1/4 (24) = 8x

13/4 (24) = 8x

316/4 = 8x

78 = 8x

78/8 = x

9 3/4 = x

ZanzabumX [31]

Answer:

$\huge\boxed{\sf C.}$

Step-by-step explanation:

sin 45 = opposite / hypotenuse

Where opposite = x , hypotenuse = 4

sin 45 = x / 4

$\sf \frac{\sqrt{2} }{2 } = \frac{x}{4} \\\\x = \frac{4\sqrt{2} }{2} \\\\x = 2\sqrt{2} \\\\\rule[225]{225}{2}$

Hope this helped!
