Answer:
C
Step-by-step explanation:
Hose A:
60 gallons every 15 minutes mean:
60 / 15 = 4 gallons per minute
For Hose B:
If we put x = 1, we can find gallons (y) per minute (x)
y = 3 x
y = 3(1)
y = 3
That means 3 gallons per minute
Thus, the rate of Hose A is 1 gallon per minute more than the rate of Hose B. Option C is correct.
Answer:
AB = 6.5
Step-by-step explanation:
C = 59°
AC = 7
CD = 6
AB = ?
Apply the Law of Cosines, which is AB² = AC² + CD² - 2(AC)(CD)*Cos(C)
AB² = 7² + 6² - 2(7)(6)*Cos(59)
AB² = 85 - 43.26
AB² = 41.74
AB = √41.74
AB = 6.5 (nearest tenth)
Answer:42x
Step-by-step explanation:
Answer:
4.5 ft
Step-by-step explanation:
Given that the two fugures in the question above are similar, it means they have the same shape, even though they are if different sizes, the ratio of their corresponding sides are proportional. Thus,
18/x = 8/2
Let's solve for x as required.
We have,
18/x = 8/2
=>Cross multiply:
18 × 2 = 8 × x
36 = 8x
=>Divide both sides by 8
36/8 = x
4.5 = x
x = 4.5 ft
The first option is our answer = 4.5 ft
