Find the missing number in this proportion. 6 16 = 30 ?

Slav-nsk [51]

80 because of you cross multiply 6 times x and 30 times 16 you get 480 and 6 divided by 480 is 80

6/16=30/?
6x=480
Divided by 6
?=80

The formula for finding the volume of a nose cone of an aircraft is V = (pi * d ^ 2 * h)/6 where d is the diameter of the base o

adell [148]

Answer:

$h=\frac{6V}{\pi d^2}$

Step-by-step explanation:

we have

$V=\frac{\pi d^2h}{6}$

Solve for h

That means ----> isolate the variable h

step 1

Multiply by 6 both sides

$6V=\pi d^2h$

step 2

Divide by $\pi d^2$ both sides

$h=\frac{6V}{\pi d^2}$

a teacher plans a simulation to estimate the probability that a student will pick a vowel out of a bag of 26 tiles, each with a

Alex Ar [27]

Answer:

Yes

Step-by-step explanation:

Given that a teacher prepares 26 tiles with 5 vowels numbered 1 and 21 consonants numbered 2.

The probability for drawing vowel = $\frac{5}{26}$

Prob for consonant = $\frac{21}{26}$

If number of trials is atleast 30 we can expect reliable results.

Here the results are recorded for 120 times at random.

Since number of trials is large, we can expect a reliable and accurate results representing the actual probability.

This is because more the number of trials, the less would be the margin of error i.edeviationfrom the expected probability would be minimum

Find the midpoint of the line segment joining the points (5,6) and (-1,-6).

kumpel [21]

Answer:

The midpoint is (2,0)

Step-by-step explanation:

To find the x coordinate of the midpoint, add the x coordinates of the endpoint and divide by 2

(5+-1)/2 =4/2 =2

To find the y coordinate of the midpoint, add the y coordinates of the endpoint and divide by 2

(6+-6)/2 =0/2 =0

The midpoint is (2,0)
