Answer:
A h+p ≤15
50h+500p ≥ 2500
Step-by-step explanation:
h = headphone and
p = pianos
We can only ship a maximum of 15 total
h+p ≤15
We must sell at least 2500 dollars of product. Headphones are 50 and pianos are 500
50h+500p ≥ 2500
<h2>B . TT →T</h2><h2>..............</h2><h2>................</h2><h2>....................</h2>
Answer:
Step-by-step explanation:
Let the speed of the car is c and speed of the plane is p.
<h3>We are given:</h3>
The speed of the plane is 7 times the speed of the car
The distance traveled is
The time difference to travel this same distance is 3 hours.
<h3>We know that:</h3>
- d = ts, where d- distance, t- time, s - speed
Find the time for car and plane and their difference.
<h3>Car</h3>
<h3 /><h3>Plane</h3>
- t = d/s = 315/p = 315/(7c) = 35/c
<h3 /><h3>The difference</h3>
<u>Solve it for c:</u>
- (315 - 45)/c = 3
- 270/c = 3
- c = 270/3
- c = 90 km/h
Now find the speed of plane:
As we see, Jenny is right
Answer:
Step-by-step explanation:
Complementary angles mean that the sum of the angles add up to . We can use algebra to solve for and then to determine .
(substitution)
∴
