Answer:
The last one
Step-by-step explanation:
-4 1/3 is less than -1 3/4 because its farther on the negative side and -1 3/4 is closer to the positive side
Answer:
3.84 * 10^0
Step-by-step explanation
Given the following values;
a = 4.8 × 104 and that b = 8 × 10−3
We are to find the product ab
ab = (4.8 × 10^4)(8 × 10^−3)
ab = (4.8*8)(10^4 * 10^-3)
ab = 38.4 * 10^(4-3)
ab = 38.4 * 10^-1
ab = 3.84 * 10 * 10^-1
ab = 3.84* 10^0
<em>Hence the product in standard form is expressed as 3.84 * 10^0</em>
let
r--------> Alvin's average paddling rate in km/hour
y -------> speed of the current
in km/hour
we know that
speed= distance/time
------> solve for distance
distance=speed*time
to Campsite against the current
speed=r-y-----> speed=(r-3)
time=8 hours
distance=(r-3)*8------> equation 2
From Campsite with the current
speed=r+y-----> speed=(r+3)
time=3 hours
distance=(r+3)*3------> equation 1
equate equation 1 and equation 2-----> because is the same distance
(r+3)*3=(r-3)*8----> 3r+9=8r-24----> 8r-3r=24+9-----> 5r=33----> r=6.6 km/hour
therefore
the answer is
Alvin's average paddling rate is 6.6 km/hour
7 games.
18×7=126
483+126=609
21×7=147
462+147=609
After 7 games each will have 609 points.
