Let the shares be 4x and 7x

Now 4x + 7x = 1980

11x = 1980

x = 1980/11

x = 180

So the shares are

4x = 4(180) = 720

7x = 7(180) = 1260

Answer:


Step-by-step explanation:

Rewrite the ratio in equation form:

4:7= 4x+7x

Now write the equation with 1980 as the answer

4x+7x=1980

Simplify

11x=1980

now divide by 11 on both sides to isolate the variable

11x/11=x

1980/11=180

so x=180

180*4=720

180*7=1260

Check: 1260+720=1980

bezimeni [28]

Answer:

How high is the stack of the two books? novel and 3/4 inches and dicitonary 41/2
sergejj [24]
3/4 + 4 1/2 = 5 1/4

If you mean that the dictionary is 41/2 then the answer = 3/4 + 20 1/2 = 21 1/4. That's a big diction though and not likely measured correctly.

The gas tank of a car is filled with a nozzle that discharges gasoline at a constant flow rate. Based on unit considerations of
Cloud [144]

Answer:

It is going 84.12s = 1 minute and 24.12 seconds to fill the tank.

Step-by-step explanation:

The filling time of a gas tank can be given by a first order function in this format:

F(t) = V - r*t

In which F(t) is the current amount of fuel in the tank(in L), V is the volume of the tank(in L), r is the discharge rate of the tank(in L/s) and t is the time in seconds.

Finding the values of the parameters:

The tank is completly empty, so F(t) = 0.

The volume of the tank is 14 gallons. However, the problem states that the volume of the tank is measured in liters.

Each gallon has 3.78L.

So V = 14*3.78 = 53L

The discharge rate for the gas is 38.0 l/min. However, the problem states that the discharge rate is in L/s. So, to find the value of r, we solve the following rule of three.

38 L - 60s

r L - 1s

60r = 38

r = \frac{38}{60}

r = 0.63

Solving the equation:

F(t) = V - r*t

0 = 53 - 0.63t

0.63t = 53

t = \frac{53}{0.63}

t = 84.12s

It is going 84.12s = 1 minute and 24.12 seconds to fill the tank.
