Jada walks up to a tank of water that can hold up to 10 gallons. When it is active, a drain empties
water from the tank at a constant rate. When Jada first sees the tank, it contains 7 gallons of water.
Three minutes later, the tank contains 5 gallons of water.
Type your answers in the boxes below.
C. How many minutes before Jada arrived was the water tank completely full?
Answer:
3 minutes and 30 seconds
Step-by-step explanation:
7-5 = 2
3/2 = 1.5 gallons that empty per each minute
1.5 times 3 (minutes) = 4.5 gallons emptied
Remaining gallons to empty = 0.5
0.5 gallons to empty will take 30 seconds

Answer:
A. Distance KL = 7.36 m
B. Height ML = 4.25 m
C. The maximum height is 6.96 m
Step-by-step explanation:
A. Determination of distance KL
Hypothenus = KM = 8.5 m
Angle θ = 30°
Adjacent = KL =?
Cos θ = Adjacent / Hypothenus
Cos 30 = KL / 8.5
0.866 = KL / 8.5
Cross multiply
KL = 0.866 × 8.5
KL = 7.36 m
Thus, the distance is 7.36 m
B. Determination of height (ML)
Hypothenus = KM = 8.5 m
Angle θ = 30°
Opposite = ML =?
Sine θ = Opposite /Hypothenus
Sine 30 = ML /8.5
0.5 = ML / 8.5
Cross multiply
ML = 0.5 × 8.5
ML = 4.25 m
Thus, the height is 4.25 m
C. Determination of the maximum height.
Hypothenus = KM = 8.5 m
Angle θ = 55°
Opposite = ML =?
Sine θ = Opposite /Hypothenus
Sine 55 = ML /8.5
0.8192 = ML / 8.5
Cross multiply
ML = 0.8192 × 8.5
ML = 6.96 m
Thus, the maximum height is 6.96 m

x + 2x + x + 15 = 100
Step-by-step explanation:
Shortest side = x
One side twice length of Shortest side = 2x
Another side 15 more = x + 15
Hence, perimeter
=> x + 2x + x + 15 = 100

A woman wishes to rent a house within 9 miles of her work. If she lives x miles from her work, her transportation cost will be cx dollars per year, while her rent will be 4c/( x + 1) dollars per year, where c is a constant taking various situational factors into account. How far should she live from work to minimize her combined expenses for rent and transportation? Use the methods outlined in this section to find the minimum.
Answer:
the woman has to live 1 mile from work to minimize the expenses
Step-by-step explanation:
Given the data in the question;
the distance within 9 miles ⇒ 0 < x > 9
Total costs Q = cx + 4c/( x + 1)
costs should be minimum ⇒ dQ/dx = 0
⇒ d/dx [ cx + 4c/( x + 1) ] = 0
⇒ ( x + 1)² = 4
take square root of both side
√[ ( x + 1)² ] = √4
x + 1 = 2
x = 2 - 1
x = 1
Therefore, the woman has to live 1 mile from work to minimize the expenses

Answer:
14.42cm and 59 degrees
Step-by-step explanation:
Use the pythagorean theorem to find the length of AB
24^2 + AB^2 = 28^2 ---> 14.42
Do arcsin(24/28) to get 59 degrees since 24 is the opposite and 28 is the hypotenuse.
