Answer:
$7
Step-by-step explanation:
Your two equations are ...
Double the second equation and subtract the first:
2(2s +4t) -(4s +6t) = 2(42) -(70)
2t = 14 . . . . . simplify
t = 7 . . . . . . . divide by 2
The cost of each tie is $7.
Answer:
The answer is C (46)
Step-by-step explanation:
Since the measurement of the triangle is 180 then you must subtract 180 by 88 to create 92 and divided that 92 by 2 to get 46.
Answer:
The slope would be 0
Step-by-step explanation:
Perimeter of a rectangle: 2(l+w)
Let width be 'x'
Length is 3 meters more than twice 'x'
Length= 2x+3.
L= x
W = 2x+3
Formula =
2(x+2x+3)
2(3x+3)
6x+6.
6(x+1)
Answer:
The height of the new cones will be 16.5 inches.
Step-by-step explanation:
We know that,
The volume of a cone is,

Where, r is the radius of the cone,
h is the height of the cone,
In the original cone,
r = 22 inches,
h = 66 inches,
Thus, the volume would be,

Also, for the new cone,
r = 44 inches,
Let H be the height,
So, the volume of the new cone would be,

According to the question,



Hence, the height of the new cones will be 16.5 inches.
