Jada traveled 135 miles in 3 hours.Andre traveled 228 miles in 6 hours.Both jada and Andre traveled at a constant speed

Vladimir [108]

Answer:

(a) 45 miles

(b) 38 miles

(c) Jada travels faster than Andre.

Step-by-step explanation:

(a) First we calculate the speed at which Jada travelled:

$Speed = \frac{distance}{time} \\\\\\s = \frac{d}{t}$

$s = \frac{135}{3} \\\\\\s = 45 miles/hour$

Since Jada travels at constant speed throughout the journey, we can calculate the distance traveled in 1 hour:

$distance = speed * time\\\\\\distance = 45 * 1$

distance = 45 miles

Jada travels 45 miles in 1 hour.

(b) We calculate the speed at which Andre travelled:

$Speed = \frac{distance}{time} \\\\\\s = \frac{d}{t}$

$s = \frac{228}{6} \\\\\\s = 38 miles/hour$

Since Andre travels at constant speed throughout the journey, we can calculate the distance traveled in 1 hour:

$distance = speed * time\\\\\\distance = 38 * 1$

distance = 38 miles

Andre travels 38 miles in 1 hour.

(c) Jada travels faster than Andre because he has a higher speed (45 miles/hour) than Andre ( 38 miles/hour).

A circular pool with a 10 foot diameter is surrounded by a deck. What is the area of the deck which surrounds the pool? use 3.14

zavuch27 [327]

Answer:

146.5 sq. feet.

Step-by-step explanation:

Area of the deck = Large Square (with 15 ft side) - Circular Pool (with radius 10/2=5)

Large Square area = $s^2=(15)^2=225$

Circular Pool area = $\pi r^2=\pi (5)^2=\pi (25)\\=25(3.14)\\=78.5$

Thus, area of deck surrounding pool = $225-78.5=146.5$ sq. feet

Ruden bought 6 new books for his collection, increasing his collection by 12%. How many books did he have before his purchase?

forsale [732]

Answer:

he had 44 books before he bought those 6

Step-by-step explanation:

If you multiply 6 times 2 it is 12, which means if you take away 12 from 100 that is 88. if you divided 88 by 2 (the same thing you did to the 6 to make it 12%) that would be 44.

X to the 2 power -6 when X = -14

-14x-14 = 196 then subtract -6 from 196 because they'll cancel each other out. the answer is 190.
