Answer:
Add 47.6 and 39.75, then round the answerStep-by-step explanation:
If Ramina found the length of two pieces of ribbon to be 47.6 inches and 39.75 inches, the effective strategy of finding the sum of the two lengths is to:
1) First is to add the two values together
47.6 + 39.75
= (47+0.6)+(39+0.75)
= (47+39)+(0.6+0.75)
= 86 + 1.35
= 87.35
2) Round up the answer to nearest whole number.
87.35 ≈ 87 (note that we couldn't round up to 88 because the values after the decimal point wasn't up to 5)
Option C is correct
Answer:
B. Round 39.75 to 40 and 47.6 to 48, then add.

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.

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.
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.

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.

Which statement correctly compares the function shown on this graph with
the function y= 4x+2?
1 2 3 4 5
O A The function shown on the graph has a greater rate of change and
a higher starting point
O B. The function shown on the graph has a smaller rate of change, but
a higher starting point
O C. The function shown on the graph has a smaller rate of change and
a lower starting point
O D. The function shown on the graph has a greater rate of change but
a lower starting point
PLEASE ANSWER
Answer:
B. The function shown on the graph has a smaller rate of change, but a higher starting point.
Step-by-step explanation:
Rate of change = slope of a linear graph.
Given the linear function, [tex] y = 4x + 2 [/tex] , the rate of change here is represented by the slope of the line, which is 4.
Let's find the rate change of the function represented on the graph using slope formula:
Rate of change = [tex] \frac{y_2 - y_1}{x_2 - x_1} [/tex]
Use coordinates of any two points on the line. Let's take,
[tex] (0, 4) = (x_1, y_1) [/tex]
[tex] (1, 7) = (x_2, y_2) [/tex]
Rate of change = [tex] \frac{7 - 4}{1 - 0} = \frac{3}{1} = 3 [/tex]
Rate of change of the linear function of the graph = 3.
Thus the function on the graph has a smaller rate of change, than the function, y = 4x + 2.
The starting value of a function is the y-intercept, that is, the value of y, when x = 0. It is the point at which the line intercepts the y-axis.
The starting value of the linear function, y = 4x + 2 is 2.
The starting value of the function on the graph is 4. At this point, x = 0.
Thus, the function on the graph has a higher starting point.
The statement that correctly compares the function shown on this graph with the function y= 4x+2 is:
B. The function shown on the graph has a smaller rate of change, but a higher starting point.
