Step-by-step explanation:
Work out 32 as a product of prime factors in index form
First find out the factor for 32
32 can be break into 16 times 2
16 can be break into 8 times 2
8 can be break into 4 times 2
4 can be break into 2 times 2
So, 32 can be written as
Answer:
The index form of the 32 is
Answer:
6.28 miles
Step-by-step explanation:
How far Michelle bike around the bicycle trail is the circumference or perimeter of bicycle trail.
This is given by:
where d=2 miles is the diameter of the bicycle trail.
We substitute to get:
Therefore she travelled approximately 6.28 miles
First, we need to find the area of wall we need to cover. The room is 10 by 12 by 8 feet. I'm assuming that we only need to wallpaper the ceiling and side walls. It would be weird to wallpaper the floor when there is carpet/tiling.
Ceiling area:
Wall area:
Total area:
Now, we subtract 15 feet for each window and door. There are two windows and two doors.
412 square feet of wall needs to be wallpapered. Dividing this by 70 (the square footage covered by one roll) gives something a little less than 6.
6 full rolls of wallpaper will be needed to fully wallpaper the room.
Answer:
c. Substitute 22 for x in the equation.
Step-by-step explanation:
The scatter plot of this question is missing, so i have attached it.
The slope equation of this is written as;
y = mx + b
Where;
y is the values in the y-axis
x is the values in the x-axis
b is the intercept on the x-axis
Now, from the scatter plot of the trend line, we can see that the values in the x-axis represent the number of years after 1970 while the y-axis shows us the price of gas per gallon for each corresponding year.
Now, we want to use the trend line equation be used to predict the cost of gas per gallon in the year 1992.
Year 1992 means 22 years after 1992. Since we have our y-intercept from the scatter plot to be 0.25, then to find the cost of gas per gallon in the year 1992, we will just plug in 22 for x and 0.25 for b into the slope line equation.
