Answer:
22(c)
Step-by-step explanation:
Our current proportion is
15 miles
-------------
1 hour
We need feet per second.
Lets convert!
15 miles= 79200 feet(used googl to find this)
1 hour=3600 seconds(also used googl to find this)
( i know its not spelled that way brainly wont let me write the whole word out)
Now, our proportion is:
79200 feet
-----------------
3600 seconds
HOWEVER, this can be simplified!!!!
79200/3600=22
Final answer: 22, or C.
ivied distance by time:
100 meters / 15 seconds = 6.67 meters per second
Answer: 3
Step-by-step explanation: the absolute value of the number before the sin/cos wave is always the amplitude of the function.
Here, it is the abs(-3)=3
The y-axis usually represents height and the x-axis represents time, so I am assuming that this is the correct answer.
<span>Mean = 270
Standard deviation = 10
x = 255
Formula for z-score, z = (x - mean)/SD
z = (255 - 270) / 10
=> z = -15 / 10 => z = -1.5
So by referring to z-table, -1.5 correlates to 0.0668 that implies to 0.07
So 7% of the boxes of Apples weight less than 255oz.
The percentage of boxes is in the range of 255 oz and 270 oz,
Now calculating the requiring percentage 50% - 7% = 43%</span>
Answer:first choice
Step-by-step explanation:
25+12.50h<_ 100
<_ means he can spend exactly 100 or less because that's all he has
Subtract 25 on both sides
12.50h<_ 100-25
12.50h<_ 75
Divide by 12.50
h<_ 6
