A store sells two kinds of candles, scented and unscented. The scented candles burn 310 inch in 15 hour. The unscented candles burn 46 inch in 13 hour.
Calculate the unit rate of scented candles
Answer:
Unscented candles : unit rate = 3.538 inches / hour
Step-by-step explanation:
Scented candles :
Burns 310 inches on 15 hours
Unscented candles :
Burns 46, inches in 13 hours
The unit rate of unscented candles :
Total inches burnt / total number of hours
46 inches / 13 hours
= 3.538 inches per hour
For scented candles :
Total inches burnt / total number of hours
310 inches / 15 hours
= 3.538 inches per hour
= 20.667 inches / hour

An internet download speed is 4.2 MB/S (constant). How long will it take to download a 30 GB file?
And with 900 KB/S?
Answer:
Time with 4.2MB/S speed = 7314.3 seconds
Time with 900 KB/S speed = 34952.5 seconds
Step-by-step explanation:
Given that:
Internet download speed = 4.2 MB/S
File to download = 30 GB
1 GB = 1024 MB
30 GB = 30*1024 = 30720 MBS
Time required = [tex]\frac{30720}{4.2}[/tex]
Time required = 7314.3 seconds
With 900 KB/S
1 MB = 1024 KB
30720 MB = 30720 * 1024 = 31457280 KBS
Time = [tex]\frac{31457280}{900}=34952.5\ seconds[/tex]
Hence,
Time with 4.2MB/S speed = 7314.3 seconds
Time with 900 KB/S speed = 34952.5 seconds
Answer:
Time with 4.2MB/S speed = 7314.3 seconds
Time with 900 KB/S speed = 34952.5 seconds
Step-by-step explanation:
Given that:
Internet download speed = 4.2 MB/S
File to download = 30 GB
1 GB = 1024 MB
30 GB = 30*1024 = 30720 MBS
Time required =
Time required = 7314.3 seconds
With 900 KB/S
1 MB = 1024 KB
30720 MB = 30720 * 1024 = 31457280 KBS
Time =
Hence,
Time with 4.2MB/S speed = 7314.3 seconds
Time with 900 KB/S speed = 34952.5 seconds

The small medium from in center to all the three sides of triangle is equal.
The length of the SQ is 5 units.
What is in-center of triangle?The in-center of a triangle is the point of intersection of all the three interior angle bisectors of a triangle.
The small medium from in center to all the three sides of triangle is equal. Thus,

Given information-
The length of MR is 12 units.
The length of MS is 13 units.
In the [tex]\Delta MRS, \angle MRS[/tex] is the right angle triangle. Thus by the Pythagoras theorem,
[tex]MS^2=MR^2+RS^2[/tex]
Rewrite the equation as,
[tex]RS^2=MS^2-MR^2[/tex]
Put the values,
[tex]RS^2=13^2-12^2\\RS^2=169+144\\RS^2=25\\RS=\sqrt{25}\\RS=5\\[/tex]
Thus the length of RS is 5 units. As the length of RS is equal tot he length of the SQ. Thus,
[tex]SQ=RS=5[/tex]
Hence the length of the SQ is 5 units.

A right rectangular prism has a length of 18 meters, a width of 5 meters, and a height of 6 meters. What is the volume, in cubic meters, of the prism?
Answer:
540 m^3
Step-by-step explanation:
We will use the formula V = Bh where B is the base and h is the height. To find the base, we will multiply the length times the width .
18 m * 5 m = 90 m^2
Them, we will multiply the height.
90m^2 * 6 m = 540 m^3
