The answer is 1,230. All you have to do is add everything on the right side you don’t have to worry about anything on the left.
Answer:
2 miles
Step-by-step explanation:
Their combined speed (speed of closure) is 80 mph + 40 mph = 120 mph.
120 mi/h = 120 mi/(60 min) = 2 mi/min
The distance between the trains at the 1-minute mark is ...
(1 min) · (2 mi/min) = 2 mi
They were warned when two miles apart.
Calculation:
First, converting R percent to r a decimal
r = R/100 = 5%/100 = 0.05 per year,
then, solving our equation
I = 20 × 0.05 × 2 = 2
I = $ 2.00
The simple interest accumulated
on a principal of $ 20.00
at a rate of 5% per year
for 2 years is $ 2.00.
<1, 1, 1> × <1, 0, 1> = <1, 0, -1>
The cross product of the normals of the planes gives the direction vector of their line of intersection.
Answer:
x = 20/33
Step-by-step explanation:
-6.6x = -4
Divide both sides by -6.6.
x = -4/(-6.6)
x = 40/66
x = 20/33
