Answer:
h = 3
Step-by-step explanation:
Dividing by a fraction is the same as multiplying by its reciprocal.
So h / (1/2) is the same as h * 2 or 2h
2h = 6
Divide both sides by 2 to isolate the variable h.
2h/2 = 6/2
h = 6/2
h = 3
I’m guessing that this is for systems of equations?
n - nickels
d - dimes
These are the equations you start off with.
n = 5d-2
0.95 = 0.10d+0.05n
Substitute the top equation for n into the variable n in the bottom equation.
0.95 = 0.10d+0.05(5d-2)
Solve for d.
0.95 = 0.10d+0.25d-0.10
1.05 = 0.35d
3 = d
Substitute d into the top equation and solve for n.
n = 5(3)-2
n = 15-3
n = 12
There are 3 dimes and 12 nickels in the coin purse! Hope this helped <3
Answer:
F. None of the above
Step-by-step explanation:
A cone is produced by rotating the shape about line m.
The height of the cone will be 0.5 because it's perpendicular to the base.
Since the height is 0.5, the answer is not A or B.
The circular base is formed by the line split into two "1"s. Each "1" is the radius, together, the diameter of the base.
Since r = 1, the answer is not C.
Since d = 2r = 2(1) = 2, the answer is not D.
∴ The answer is none of the above, F.
Answer:
Step-by-step explanation:
a. the balloon is rising because the slope is positive. the slope is 40 because when you simplify y-160 = 40 (x-1) it gets you y = 40x +120
b. it is ascending (bc positive) at 40 feet per minute
c. it was at 120 feet in the air. The 120 is the y intercept
Answer:
perimeter:- 8x
Step-by-step explanation:
since,
length= 3(width)
length= 3x
and, perimeter= 2(l + b)
= 2(3x + x)
= 2(4x)
perimeter = 8x
