The model shows the expression 20 + 16.
Which expression is equivalent to this sum?
O4(5) + 4
4+5+4
O4(5+4)
5(4+4)
Answer:
4 (5 + 4)Step-by-step explanation:
20 + 16
= 4 (5 + 4)
= 4(5) + 4(4)
= 20 + 16
therefore, the answer is 4 (5 + 4)
Tina is saving to buy a notebook computer. She has two options. The first option is to put $300 away
initially and save $30 every month. The second option is to put $200 away initially and save $50 every
month. After how many months would Tina save the same amount using either option? How much
would she save with either option?
Plzzz hellpppp
Answer:
After 5 months, she will save the same amount using either option.
She would have saved $450 with either option.
Step-by-step explanation:
Set up expressions to represent the amount of money saved for each saving option, where x is the number of months
The first one can be represented by 30x + 300
The second one can be represented by 50x + 200
Set these equal to each other and solve for x:
30x + 300 = 50x + 200
300 = 20x + 200
100 = 20x
5 = x
So, after 5 months, Tina will save the same amount of money with both options.
To find how much she will save, plug in 5 as x into either expression:
30x + 300
30(5) + 300
150 + 300
= 450
So, she would have saved $450 with either option.
The water level of a lake fell by 1 1/2 inches during a 1 2/3-week-long dry spell. Find the average rate at which the water level changed every week.
Answer: The average rate at which the water level changed every week = [tex]-\dfrac35[/tex] inches per week.
Step-by-step explanation:
Given: Change in water level in [tex]1 \dfrac23[/tex] week = [tex]-1\dfrac12[/tex] inches = [tex]-\dfrac32[/tex] icnhes
To find : The average rate at which the water level changed every week.
i.e. Change in water level per week.
As [tex]1\dfrac23 = \dfrac52[/tex]
Change in water level in 1 week = [tex]-\dfrac{3}{2}\div\dfrac52 = -\dfrac32\times \dfrac25= -\dfrac35[/tex]
Hence, the average rate at which the water level changed every week = [tex]-\dfrac35[/tex] inches per week.
We want to find the average rate of change at which the water level changed in a given time period.
We will find that the average rate of change is:
[tex]r = - 0.9 in/week[/tex]
We define the average rate of change as the quotient between the total change and the time it takes.
Here we have:
total change = -(1 + 1/2) in
Time = (1 + 2/3) weeks
Then the average rate of change is:
[tex]r = \frac{-(1 + 1/2) in}{(1 + 2/3) weeks} = - 0.9 in/week[/tex]
This means that the water level decreases, in average, 0.9 inches per week.

(b^5)^3 x b^4 simplify
Answer:
b^19
Step-by-step explanation:
In the first factor, we need to use a formula to simplify. The formula is x^a^b = x^(ab). So that means that our first factor simplifies to b^15. Then we add up the powers to simplify it even more. b^15 * b^4 = b^19 using another formula. Therefore b^19 is the answer.
There are 365 days in a year and 24 hours in a day. An airport camera records for 18 hours and then automatically resets itself to start recording again how many times does the video camera reset itself in a year.
pls help
The answer is 486.6
There are 8,760 hours in a year, so 18 divided by 8,760 would = 486.6
Answer:
Step-by-step explanation:
You could do it this way.
How many hours are there in a year?
365 * 24 = 8760 hours.
This camera does not recognize days. It works on hours. Every 18 hours it resets. So
8760/18 = 486 and 2/3 times.
Obviously it cannot have 2/3 of a day. Normally you would round up, but this time you round down.
The answer is 486 times.
2/3 * 24 = 16
The camera would reset 2 hours into the next day.

A whole number k is greater than 3. Which of the following is true about k/3?
Answer:
D) It is greater than 1.
Step-by-step explanation:
Since k is greater than 3, it could not be between 0 and 1/3 and also could not be between 1/3 and 1
We also know that it is not equal to 1 because it is greater than 3.
Therefore, it is greater than 1.
