If x varies directly as y, and x=6 when y=24, What is x when y=120

Mathematics
1 answer:
Artyom0805 [142]2 years ago
4 0

Answer:

30

Step-by-step explanation:

x = ky

k = constant term

6 = k24

divide both sides by 24

k = 1/4

What is x when y=120

x = ky

x = (1/4) X 120

X = 30

slope = (57 - 35)/(3 - 1) = 11

 

y = 11 x + b

 

35 = 11 (1) + b

b= 24

 

y = 11x + 24

 

y = 11(5) + 24 = 79

The value of a house has increased by 5% the house is now valued at £609000 what is the value of the house before the increase?
lutik1710 [3]

Answer:

Current \ price = 609000\\\\Let \ the \ original \ price \ be = x\\\\\% increase = 5 \% \ of \ x = \frac{5}{100} \times x = \frac{5x}{100}\\\\Price \ after \ increase, current\ price = \frac{5x}{100} + x\\\\

=> 609000 = \frac{5x}{100} + x\\\\=>609000 = \frac{105x}{100}\\\\=> x = \frac{609000 \times 100}{105}\\\\x = 580000

Therefore original price = $580,000

He radius r of a circle is increasing at a rate of 6 centimeters per minute. find the rate of change of the area when r = 35 cen
sergij07 [2.7K]
You can solve this problem by following the steps below:

 1. You need the formula for calculate the area of a circle, which is:

 A=πr²

 "A" is the area of the circle
 "r" is the radius of the circle (r=35 centimeters).

 2. Now, you must take the derivative. Then, the rate of change of the area is:

 dA/dt=(2πr)(dr/dt)

 3. The radius of change of the radius "r" with respect to time, is:

 dr/dt=6 cm/min

 4. Then, you have:

 dA/dt=(2πr)(dr/dt)
 dA/dt=2π(35 cm)(6 cm/min)
 dA/dt=420π cm²/min
