wheres the question part i can't give an answer if I don't know whats its asking
Answer:
40
Step-by-step explanation:
The formula for the perimeter of a rectangle is P = 2l + 2w. Since the length is 8 times the width, l = 8w. You can plug this into the equation.
<em>P = 2(8w) + 2w</em>
<em>P = 16w + 2w</em>
P = 18w
Now, plug in the given value for perimeter, and solve for w.
<em>90 = 18w</em>
<em>(90)/18 = (18w)/18</em>
5 = w
Since the width is equal to 5, you can now solve for l.
<em>l = 8w</em>
<em>l = 8(5)</em>
l = 40
The length of the diagonal is equal to 40.
The answer would be 10 minutes. If you look at the highest point from distance and you go down to the time it lands on 10.
I hope this helps love! :)
Answer:
x = 15.8
Step-by-step explanation:
let the number be x
according to the question equation is
x*5 - 2 = 77
5x - 2 = 17
5x = 77 + 2
5x = 79
x = 79/5
x = 15.8
The tenths place would be the digit right after the decimal point, and we want to round 479.16 to the nearest tenths.
The number in the tenths place is 1. Now we have to decide if we're going to round up or down
- If the next digit is greater than or equal to 5, we round up (add 1 to the digit); if it isn't, then we round down (the digit stays the same).
The digit after the tenths place is "6", which is greater than 5. Thus, the "1" is rounded up to a "2"
Answer: 479.16 to the nearest tenths is 479.2.
Let me know if you need any clarifications, thanks!
