Find the measure of the exterior angle.
Answer:
u = 143º
Step-by-step explanation:
Sum of angles in a triangle is 180
The unknown angle IN the triangle
x + 90 + 53 = 180
x + 143 = 180
x = 37º
x and u are supplementary angle which total 180
u + 37 = 180
u = 143º

Answer:
Step-by-step explanation:
So, lets just go by segment to segment, using the process of elimination to see which graph is correct.
So the first segment of all the graphs is 18-19.9.
Lets look at the numbers given to us, and see how many times values between these two numbers occur. I see 19.9 and 18.6. This is two values.
This eliminates answer C, which has three values(a frequency of 3).
All the others have 2 values however, so lets keep going.
Next we have 20-21.9. I see 9 values that are in between 20-21.9:
20.7, 21.2, 20.5, 20.4, 21.6, 21.4, 21.5, 21.5, 21.9
Both B and D have graphs with 9 values that are between 2-21.9, however A only has 8 values.
Now lets look at 22-23.9. I see 8 values between 22-23.9:
22.2, 22.7, 22.1, 23.1, 23.8, 22.6, 23.9, 23.4
This eliminates D, which only has 7 values, but B does have 8 values.
So this means that B is the answer!
Hope this helps!
A large tank is filled to capacity with 700 gallons of pure water. Brine containing 4 pounds of salt per gallon is pumped into the tank at a rate of 7 gal/min. The well-mixed solution is pumped out at a rate of 14 gallons/min. Find the number A(t) of pounds of salt in the tank at time t.
Answer:
[tex]A(t) = 1400(1 - e^{\frac{-t}{50}})[/tex]
Step-by-step explanation:
The net mass flow rate dA/dt = mass flow rate in - mass flow rate out
mass flow rate in = concentration of brine in × brine flow rate in = 4 lb/gal × 7 gal/min = 28 lb/min
Let A(t) be the amount of salt at time t. The concentration of salt in the tank at time, thus C = amount of salt/volume of tank = A(t)/700 lb/gal.
Since the well mixed solution is pumped out at a rate of 14 gal/min, the mass flow rate out = concentration of salt in tank × volume flow rate out = A(t)/700 lb/gal × 14 gal/min = m(t)/50 lb/min
So, dA/dt = mass flow rate in - mass flow rate out
dA/dt = 28 lb/min - A(t)/50 lb/min
dA/dt = 28 - A(t)/50
dA/dt = [1400 - A(t)]/50
separating the variables, we have
dA/[1400 - A(t)] = dt/50
integrating both sides, we have
∫dA/[1400 - A(t)] = ∫dt/50
-1/-1 × ∫dA/[1400 - A(t)] = ∫dt/50
1/-1 × ∫-dA/[1400 - A(t)] = ∫dt/50
-1 × ㏑[1400 - A(t)] = t/50 + C
-㏑[1400 - A(t)] = t/50 + C
㏑[1400 - A(t)] = -t/50 - C
taking exponents of both sides, we have
[tex]1400 - A(t) = e^{\frac{-t}{50} - C} \\1400 - A(t) = e^{\frac{-t}{50}}e^{-C}\\1400 - A(t) = Be^{\frac{-t}{50}} ( B = e^{-C}) \\A(t) = 1400 - Be^{\frac{-t}{50}}[/tex]
when t = 0, A(0) = 0. So,
[tex]A(t) = 1400 - Be^{\frac{-t}{50}}\\A(0) = 1400 - Be^{\frac{-0}{50}}\\0 = 1400 - Be^{0}\\0 = 1400 - B\\B = 1400[/tex]
So,
[tex]A(t) = 1400 - 1400e^{\frac{-t}{50}}\\A(t) = 1400(1 - e^{\frac{-t}{50}})[/tex]
The supply function for a product is given by p = 40 + 100 underroot 2x + 9, where x is the number of units supplied and p is the price in dollars. If the price is increasing at a rate of $1 per month, at what rate is the supply changing when x = 20?
the supply changing when x=20 is 40
The window has the shape of a kite. How many square meters of glass were used to make the window?
Answer:
1568cm²
Step-by-step explanation:
28cm + 28cm = 56cm
35cm + 21cm = 56cm
56 × 56 = 3136cm²
3136cm² ÷ 2 = 1568cm²

Answer:
300°
Step-by-step explanation:
To convert from radians to degrees
degree = radian × [tex]\frac{180}{\pi }[/tex] , then
degree = [tex]\frac{5\pi }{3}[/tex] × [tex]\frac{180}{\pi }[/tex] ( cancel π on numerator/ denominator )
= [tex]\frac{5(180)}{3}[/tex]
= 5 × 60°
= 300°

Step-by-step explanation:
When the expression has an equal sign there is only one solution
6x = 150
* divide each side by 6 *
6x / 6 = x
150 / 6 = 25
we're left with x = 25
The answer would be C, because the dot is in between 24 and 26 which would be 25 and x equals 25
Three friends went to a fundraiser at a local restaurant. Each plate cost $7.95, which included a drink. A tip of 20% was left for the waitress. How much was the total cost of the meals including tip?
A.$23.85
B. $24.05
C. $28.62
D. $29.65
Answer:
C. $28.62
Step-by-step explanation:
3 · $7.95 = $23.85
[tex]\frac{y}{23.85} :\frac{20}{100}[/tex]
y · 100 = 20 · 23.85
100y = 477
100y ÷ 100 = 477 ÷ 100
y = $4.77
$23.85 + $4.77
$28.62
