we know that
![1\ mile=5,280\ feet](https://tex.z-dn.net/?f=1%5C%20mile%3D5%2C280%5C%20feet)
![1\ hour=3,600\ sec](https://tex.z-dn.net/?f=1%5C%20hour%3D3%2C600%5C%20sec)
1) <u>convert miles per hour to feet per hour</u>
![40\ miles/hour=40*5,280=211,200\ feet/hour](https://tex.z-dn.net/?f=40%5C%20miles%2Fhour%3D40%2A5%2C280%3D211%2C200%5C%20feet%2Fhour)
<u>2) convert feet per hour to feet per second</u>
![211,200\ feet/hour=211,200/3,600=58.67 feet/sec](https://tex.z-dn.net/?f=211%2C200%5C%20feet%2Fhour%3D211%2C200%2F3%2C600%3D58.67%20feet%2Fsec)
Round to the nearest whole number-------> ![59 feet/sec](https://tex.z-dn.net/?f=59%20feet%2Fsec)
therefore
<u>the answer is</u>
![59 feet/sec](https://tex.z-dn.net/?f=59%20feet%2Fsec)
Answer:
I think the answer is b. I am not sure so if I was incorrect I apologize.
Step-by-step explanation:
Answer:
The equation that models this situation is:
x = 15 × 8 or x ÷ 8 = 15
Step-by-step explanation:
- Total number of available tables = 15
- The number of guests who are seated at each of the 15 available tables = 8
Let 'x' be the total number of guests who are seated at the tables.
If have to determine how many guests (x) are seated at the tables, all we need is to multiply the 15 with 8.
so the equation becomes
x = 15 × 8 or x ÷ 8 = 15
Therefore, the equation that models this situation is:
x = 15 × 8 or x ÷ 8 = 15
The formula for a trapezoid is a=a+b/2 x h
so plug that back into the equation and you get
15=10/2 *h
15=5*h
from here, you know that 15/5 equals 3 and therefore the height of the trapezoid is 3.
Good Luck on ur Big Test!
Answer:
107.86 to 2 d.p.
Step-by-step explanation:
makes a triangle. 120 feet is the hypotenuse.
we want to find the opposite so we will use sine.
sin(x) = opp/hyp which means opp = sin(x)hyp.
opp = sin(64)120
opp = 107.86 to 2d.p.
