The answer is 0.9 if z is in the numerator and if it is in the denominator it is 1/9
Answer: 144 minutes
Step-by-step explanation:
Based on the information that has been given in the question, the minutes that the slower pipe alone can use in filling the tank can be denoted by y minutes.
Therefore, the faster pipe will fill it in 1/3 × x = x/3 minutes.
Therefore,
1/x + 3/x = 1/36
4/x = 1/36
x = 36 × 4
x = 144
The number of minutes taken by the slower pipe will be 144 minutes.
By connecting the top of the height of the bird feeder and the tip of the shadow casted, we form a right triangle. The hypotenuse is equal to the given distance between the top of the bird feeder and the top of the shadow which is equal to 19 feet.
If we let x be the height of the bird feeder and x/2 be the length of the shadow, by Pythagorean theorem,
x² + (0.5x)² = 19²
The value of x from the equation is 16.99 ft or 17 ft.
Thus, the height of the bird feeder is 17 ft and the shadow is approximately 8.5 ft.
Answer:
y= 1,000x+55,000
Step-by-step explanation:
55,000 is y intercept. 1,000x is slope.
For this question you can say:
1/8x = 10
so x is the answer and if u want to find the x you can multiply both sides of the equation by 8 so you will have:
x = 80 and that's the number
if u want to find 1/7 of 21 you should just divide 21 by 7 so you will have 3 and for the last one is same also, so the answer is 5 :)))
i hope this is helpful
have a nice day
