Answer:
40mph
Step-by-step explanation:
Using D = rt, the current variables we have are
D = 20 miles
t = 30 minutes
Since the goal is rate, we alter the equation to r = D/t.
In addition, we have to convert minutes into hours so we can
r = (20 / 30)*2/2
r = (40/60)
60 minutes is converted into an hour so the rate <em>r</em> is 40 miles per hour.
r = 40/1

Answer:
Actual volume: 150.8
Step-by-step explanation:
the equation to find the volume of a cylinder is:
V= pi (r)^2 (h)
r= radius
h= height
To get the radius, you divide the diameter by 2.
when you plug in the numbers is looks like this:
V= pi (2)^2 (12)
you'll get 150.8 ft^3
I'm not really sure which volume would be the closest, but it should be around the answer I provided
A = b - 2
a - 3b = 22
(b - 2) - 3b = 22
b - 2 - 3b = 22
-2 - 2b = 22
-2b = 24
-b = 12
b = -12
a = b - 2
a = -12 - 2
a = -14
Solution set {-14, -12}
Answer:
x = 21
Step-by-step explanation:
Given that SV is the angle bisector of ∠RST, then
∠RSV = ∠TSV, thus
∠RSV + ∠TSV = ∠RST ← substitute values
2x + 8 + 2x + 8 = 6x - 26, that is
4x + 16 = 6x - 26 ( subtract 6x from both sides )
- 2x + 16 = - 26 ( subtract 16 from both sides )
- 2x = - 42 ( divide both sides by - 2 )
x = 21
