Identify the figure that illustrates "a reflection in line k."
A water tank has two valves, one for inlet pipe and the other is outlet pipe. If the tank is empty the inlet valve is
opened, the tank will be full of water after 5 hours. If the tank is full and the outlet valved is opened, the tank
will be emptied in 8 hours. Suppose the tank is empty and both valves are opened, in how many hours will the
tank be full?
Let V be the volume of the tank. The inlet pipe fills the tank at a rate of
V / (5 hours) = 0.2V / hour
and the outlet pipe drains it at a rate of
V / (8 hours) = 0.125V / hour
With both valves open, the net rate of water entering the tank is
(0.2V - 0.125V ) / hour = 0.075V / hour
If t is the time it takes for the tank to be full, then
(0.075V ) / hour • t = V
Solve for t :
t = V / ((0.075V ) / hour)
t = 1/0.075 hour
t ≈ 13.333 hours

Four different stores are offering incentives to purchase headphones as shown below. Noisy Music Regular Price $250 Clearance Special - 15% off Loud N Sharp Regular Price $200 $5 off for every $100 spent Music Mart Regular Price $300 Mail-in rebate for $115 Head Jamz Regular Price $225 Manager special – 25% off Which store offers the lowest price?
Answer:
Head Jamz
Step-by-step explanation:
Noisy Music Regular Price $250 Clearance Special - 15% off
If 15% is off then we pay only 100-15 =85% from the original price.
$250 / 100 % = x / 85%
x= 250*85/100 = $ 212.5
Loud N Sharp Regular Price $200 $5 off for every $100 spent
If the price is 200 then will get $5+$5 =$10 discount
Final price will be 200-10 = $ 180
Music Mart Regular Price $300 Mail-in rebate for $115
$300-$115 = $ 185
Head Jamz Regular Price $225 Manager special – 25% off
If 25% is off we only pay 75% of the original price
$225/ 100% = x / 75%
x= 225*75/ 100 = $168.75 is the lowest price

The sum of the interior angles of a polygon is 2700 degrees. Calculate the number of sides.
Answer:
17 sides
Step-by-step explanation:
The sum of the interior angles of a polygon is
sum = 180° (n - 2) ← n is the number of sides
Here sum = 2700° , then
180°(n - 2) = 2700° ( divide both sides by 180° )
n - 2 = 15 ( add 2 to both sides )
n = 17
The polygon has 17 sides
Solve for b in the literal equation a+ b+ c= 180
Answer:
b = 180 - a - c
Step-by-step explanation:
To solve for b given the literal equation, a + b + c = 180:
Subtract a and c from both sides:
a + b + c = 180
a - a + b + c - c = 180 - a - c
b = 180 - a - c

En un parqueadero hay 50 vehículos. Pero si contamos sus llantas hay 140.¿Cuántos carros y motos hay? Por favor alguien que me ayude este tema es de matemáticas problemas lineales 2x2
Answer:
Carros = 20
Motos = 30
Step-by-step explanation:
Carros = x
Motos = y
x + y = 50
4x + 2y = 140
x = 50 - y
4 (50-y) + 2y = 140 (substitución)
200 - 4y + 2y = 140
- 2y = 140 - 200
y = -60/-2
y = 30
x + 30 = 50
x = 50-30
x = 20

Dan the Donut man has to buy the donut machine for 89 dollars. He then can make donuts and sell them for 2 dollars a person. How many donuts does he need to sell to make at least
$231?
Answer:
161 donuts
Step-by-step explanation:
(231+89)/2 then add one more donut as the question asked for at least $231
320/2 = 160 + one more donut = 161 donuts have to sold to make at least $231.
You have add the machine price as he wouldn't be making a profit off it if he didn't surpass what he spent for it.
Check your work by doing 161 times 2 minus 89 minus the 1 donut added and you'll get the $231. Not subtracting the one shows the profit of a dollar aka at least $231
