Answer:
(8 x 6) x b
Step-by-step explanation:
The associate property states yuo can re-associate multiplication and group under the same operation differently. This means Dave wrote (8 x 6) x b.
Answer:
40! Seconds
Step-by-step explanation:
Calculation for After how many seconds will the two fish tanks have the same amount of water
First step
Based on the information given let the equation be :
150-1/2x=120+1/4x
Second step
Now let solve for x which means that x will be the number of second by multiplying both side by 4
4(150-1/2x)=4(120+1/4x)
=600-2x=480+x
Third step
Let Add 2x on both side
600=480+3x
Third step
Let Subtract 480 on both side
600-480=480-480+3x
120=3x
Last step is to divide both side by 3
120/3=3x/3
40=x
Hence:
x=40 seconds
Therefore After 40 seconds the two fish tanks will have the same amount of water.
Pr(1/2) for both I believe. If not right sorry.
Answer:
1250 visitors per day
Step-by-step explanation:
Number of visitors per year = 3,000,000
Number of days open per year = 300
Number of hours = 9a.m to 5pm = 8 hours
Number of visitors per hour :
Number of visitors per year / (number of days per year * number of hours per day)
3000000 / (300 * 8)
3000000 / 2400
= 1250 visitors per day
It would be a great idea to narrowing it down to (2^3)^134 mod 5. now it is easier cause <span> 8 = 3 (mod 5), let's compute 3^402 (mod 5).
</span><span>3^4 = 81 = 1 (mod 5). </span>
<span>Therefore, 3^402 = (3^4)^100 * 2^2 = 1^100 * 4 = 4 (mod 5). </span>
