Answer: 17.07 centimeters, because height = Square root of the difference of the squares of 18 and 5.7.


Step-by-step explanation:

Given: The slant height of the cone (l)= 18 cm

The radius of the cone (r) =5.7 cm

Let h be the height of the cone .

We know that the above dimensions make aright triangle in a cone, such that by Pythagoras theorem

l^2=h^2-r^2\\\Rightarrow\ h^2=l^2-r^2\\\Rightarrow\ h=\sqrt{l^2-r^2}\\\Rightarrow\ h=\sqrt{18^2-5.7^2}

Thus, height = Square root of the difference of the squares of 18 and 5.7

and,

\Rightarrow\ h=\sqrt{324-32.49}\\\Rightarrow\ h=\sqrt{291.51}\\\Rightarrow\ h=17.0736639302\approx17.07\ cm

A gentleman is standing 10 feet from a streetlight. He is 5'6 tall and has a shadow of 24 feet. What is the height of the street
Goshia [24]

Answer:

Height of the streetlight ≈ 8 ft(nearest foot)

Step-by-step explanation:

The doc file displays the triangle formed from the illustration. x is the height of the street light. The distance from the gentle man to the street light is 10 ft. He  has a height of 5.6 ft  and the shadow formed on the ground is 24 ft long. The height of the street light can be calculated below.

The length of the tip of the shadow to the base of the street light is 34 ft. Similar triangle have equal ratio of their corresponding sides .

ab = 5.6 ft

The ratio of the base sides = 24/34

The ratio of the heights = 5.6/x

The two ratio are equal Therefore,

24/34 = 5.6/x

24x = 5.6 × 34

24x = 190.4

divide both side by 24

x = 190.4/24

x = 7.93333333333

x ≈ 8 ft

Height of the streetlight ≈ 8 ft(nearest foot)

Several factors influence the size of the F-ratio. For each of the following, indicate whether it would influence the numerator
enyata [817]

Answer:

(a) Increase the differences between the sample means this will increase the Numerator.

(b) Increase the sample variances will increase the denominator.

Step-by-step explanation:  

F Ratio = Variance between treatments/ Variance within treatments.  

Here,  

(a) Increase the differences between the sample means:  

  - Will increase the Numerator and  

  - Size of the F-ratio would increase  

(b) Increase the sample variances:  

 - Will increase the denominator and  

 - Size of the F Ratio would decrease.

9/10-1/3-1/5 find the fraction
Zanzabum
Find a common multiple in between the denominators.
10 and 3 and 5 -> the least common multiple is 30.

Change all the denominators to 30 by multiplying the top and bottom by the same number.

9/10=27/30
1/3=10/30
1/5=6/30

Subtract!
27/39-10/30-6/30=11/30

The answer is 11/30
