Step-by-step explanation:
2/5 x 1/3 = 2/15 inches squared
Answer:
43 cm
Step-by-step explanation:
C = 2 * pi *r
86pi = 2 * pi *r
Canceling pi from each side
86 = 2r
Divide by 2
86/2 =2r/2
43 =r
The equation that can be used to determine the time for each leg is D. 600t = 480(18 – t)
<h3>How to calculate the equation?</h3>
Speed on going ,= 600 miles per hour.
Speed on return = 480 miles per hour
Time on returning = 18 - t
Distance = Speed × Time
Distance = 480(18 - t)
The equation that can be used to determine the time for each leg will be:
600t = 480(18 – t)

Answer:
Y= X/4+2
Step-by-step explanation:
So first you find the slope and the y intercept
the slope is 1/4 and the y intercept is 2
so the equation would be Y= X/4+2
Answer:
0.5
Step-by-step explanation:
Given that height of 7 year old children are normally distributed with mean =49 inches and std deviation = 2inches
Brenda is 50 inches tall
This means her X score is 50
To convert this X score to Z score we use the formula given below
Here we know all the values of x, mu and sigma
Just substitute
Z score
=
Thus Z score of Brenda is 0.5
