Lets say the cost of her haircut is $x. This makes the cost of her perm 2x (twice as much). If lunch ($5), the perm ($2x) and the haircut ($x) cost, in total, $50, we can say:
50 = 5 + 2x + x
Combine like terms:
50 = 5 + 3x
Subtract 5 from both sides to isolate 3x
50 - 5 = 3x
45 = 3x
Divide all by 3 to isolate x
x = 45/3
x = 15
So the haircut is $15 and the perm is $30 (2*$15).
Answer:
$997
Step-by-step explanation:
Base Salary: $150 (given)
Additional information on everything he sells: 14%
He sells $6050.00 last week, so then his commision would be 14% of the $6050.
x = 150 + ( 0.14 x 6050 )
OR
14/100 x 6050
would equal: $847
Total pay for last week would equal base salary and the additional pay.
$150 + $847
= $997
His total pay for last week would equal $997.

Answer:
1.4% of connectors fail during the warranty period.
Step-by-step explanation:
We have these following probabilities:
A 90% probability that a connector is kept dry.
A 10% probability that a connectors is wet.
If a connector is dry, an 1% probability of failling.
If a connector is wet, a 5% probability of failling.
What proportion of connectors fail during the warranty period?
This is 1% of 90% and 5% of 10%. So

1.4% of connectors fail during the warranty period.
Answer:
- motorcycles: 20
- vans: 25
- cars: 135
Step-by-step explanation:
There are 3 car spaces for each non-car space, so the number of car spaces is 3/4 of the total: (3/4)×180 = 135.
The number of motorcycle spaces is half of 5 less than the remainder, so is ...
(180 -135-5)/2 = 20
and van spaces are 5 more than that: 25.
There are 20 motorcycle spaces, 25 van spaces, and 135 car spaces.

Step-by-step explanation:
R = C/(2*Pi).
So, in order to find the radius from the circumference, you use the formula R = C/(2*Pi). In other words, just divide the circumference by 2 times pi.
