Answer:
1.78 x 10^8
Step-by-step explanation:
178000000
I usually count the number of zeros first so in this case, it would be 6
178 x 10^6
This wouldn't be standard form because the number should be between 1 and 9
178 ÷ 100 = 1.78
I divided this number by 100 so I would times 10^6 by a 100
10^6 x 100 = 10^8
the answer would be 1.78 x 10^8

Answer:
9 sleeves for 22.99
Step-by-step explanation
The first pack has a unit rate of $11.49/ 4 balls
=$2.8725
The second pack has a unit rate of $16.79/6balls
=$2.798 per ball
the third pack has a unit rate of $22.99/9balls
=2.554
So, I would definitely go for the third pack since it has the least cost.
2 corners are both 45 degrees, meaning that they are both the same length.
For this we use the pythagorean theorem, but a bit modified:
a^2 + a^2 = c^2
2a^2 = 256
Solve for a:
a^2 = 128
a = 8 √2
One leg is equal to √128 or 8 √2.
2(3-1) ² / 1+1 x 3+3
Use PEMDAS
2(2) ²/1+1 x 3+3
4 ² / 2x6
16/12
1.333
He made $120.
You divide 1,320 by 22. That gives you 60. Then you times 60 by 2(which equals 120) because 60 represents the packets and he made 2 dollars per packet.
Mathematically the steps look like this:
1,320/22
=60
60(2) or 60 x 2
= 120
so $120
