Answer: X=2.7
Step-by-step explanation:
25*2-8x=12x-4
50-8x = 12x-4
subtract 50 from both sides
-8x = 12x-54
subtract 12x from both sides
-20x= -54
divide both sides by -20
X=2.7

Answer:
The angle between any two faces of this pyramid is equal to 
Step-by-step explanation:
we know that
An equilateral triangle has three equal sides and three equal internal angles of measure 60 degrees
In this problem
All the faces in the regular triangular pyramid are equilateral triangles.
therefore
The angle between any two faces of this pyramid is equal to
The number of ways to select 4 digits from 10 digits is
₁₀C₄ = 10!/(4!*6!)
= (10*9*8*7*6!)/(4*3*2*1*6!)
= (10*9*8*7)/(4*3*2)
= 210
If order is not important, the number of arrangements of 6,7,8,9 in any order is
4! = 4*3*2*1
= 24
The probability that these 4 digits are assigned is
24/210 = 0.1143
Answer:
210 kilometers
Step-by-step explanation:
<em><u>First; we are going to divide.</u></em>
60(hour in minutes) / 20 mins ...to find out what the excess distance the car went.
Which is 1/3 or 0.3333333...
<u><em>Second; we are going to combine the decimal and the whole number together.</em></u>
2 hours + 0.333333... hours = 2.3333333...hours
<u><em>Finally; we are going to multiply</em></u>
90 (km/h) * 2.33333333
Which equals ...210 kilometers!!
