Answer:
the answer 504
Explanation:
360*0.40=144
so they said 40% reggie collected main mor than 40% collected so you need to do add like 360+144=504
Hey there! I'm happy to help!
We have 5 test scores that give us an average of at least 75.
76, 85, 92, 63, x
We add these all up and divide by 5 to get 75.
Let's go backwards to find x.
We multiply by 5.
75(5)=375
We subtract all of the numbers except for x.
375-76-85-92-63=59
So, you need to earn at least 59 on the next test to achieve an average of at least 75.
Have a wonderful day! :D
First find the rate of growth using the formula of
A=p e^rt
A 7200
P 6000
E constant
R rate of growth?
T time 6 hours
We need to solve for r
R=[log (A/p)÷log (e)]÷t
R=(log(7,200÷6,000)÷log(e))÷6
R=0.03 rate of growth
Now predict how many bacteria will be present after 17 hours using the same formula
A=p e^rt
A ?
P 6000
R 0.03
E constant
T 17 hours
A=6,000×e^(0.03×17)
A=9,991.7 round your answer to get
A=9992
I think r is 1/2 but is not in the option
Step-by-step explanation:
The three ways by which we can find the 75% of 96 -
1 ) Simply multiply and extract 75% of 96 as follows -
= 75/100 * 96
= 72
2) We can write 75% as 3/4 of the total so if we multiply 3/4 with 96 we
will get 75% of 96
= 3/4 * 96
= 72
3) We can also get 75% of 96 by taking out the 1/4 rd of 96 and subtracting
from 96 we get 75% of 96
= 96 - (1/4 * 96)
= 96 - 24
= 72
