Evaluate C(7, 4) 35 210 5,040

sashaice [31]

Answer:

$\boxed{\boxed{C(7,4)=35}}$

Step-by-step explanation:

Here, we have to calculate

$C(7,4)=\dbinom{7}{4}$

From combination we know that,

$\dbinom{n}{r}=\dfrac{n!}{r!(n-r)!}$

Here,

n = 7 and r = 4, so putting these,

$\dbinom{7}{4}=\dfrac{7!}{4!(7-4)!}$

$=\dfrac{7!}{4!\ 3!}$

$=\dfrac{5040}{24\times 6}$

$=\dfrac{5040}{144}$

$=35$

A garden snail traveled 1⁄40 of a mile in 1⁄2 an hour. What was the speed of the snail?

vovikov84 [41]

A mile=5280 feet
1/40 mile*(5280 feet/1 mile)=132 feet

132 feet-------------------1/2 hour
x------------------------------1 hour
x=(132 feet*1 hour) / (1/2 hour)=264 feet/hour.

264 feet/h *(1 mile/5280 feet)=0.05 miles/ h

Solution: S=264 feet/h (≈0.05 miles/h)

To approach a runaway a plane must be 7 descent starting from the height of 3 miles above the ground. How many miles from the ru

UNO [17]

use SOHCAHTOA

S = sine

O = opposite edge

H = hypotenuse

T = Tangent

A = adjacent edge

C = cosine.

The extreme is where the runaway is indicated by the hypotenuse is the required distance. Therefore,

sine 7= 3/H

H = 3/sine 7= 24mi
