Answer:

1\frac{7}{9}

Step-by-step explanation:

\frac{5}{15}  *3 \frac{1}{3} \\

Turn the second part into an improper fraction by multiplying the coefficient (the big 3) by the denominator of the fraction. You should get 3*3 = 9. Then add that number to the numerator of the fraction to get this:

\frac{8}{15}  * \frac{10}{3}

Now, multiply directly across, so 8*10 over 15*3.

\frac{8*10}{15*3} Now multiply out:  \frac{80}{45}

You can simplify this into \frac{16}{9}

Now, see how many times the denominator goes into the numerator evenly (1 time) and subtract that from the numerator to get 1\frac{7}{9}

Farmer brown had ducks and horses one day he noticed that all of the Animals had a total of 12 heads and 32 feet how many animal
brilliants [131]

Answer:

4 horses and 8 ducks.

Step-by-step explanation:

Let the number of ducks be d and the number of horses be h.

d + h = 12

Now ducks have 2 feet and horses have 4 so:

2d + 4h = 32

Multiply the first equation by 2

2d + 2h = 24

Subtract this equation from the second equation:

4h - 2h = 32 - 24

2h = 8

h = 4.

So there were 4 horses and 12 - 4 = 8 ducks.

There are three separate, equal-size boxes, and inside each box there are four separate small boxes, and inside each of the smal
katen-ka-za [31]

Answer:

There are 51 boxes all together.

Step-by-step explanation:

Since there are three separate, equal-size boxes, and inside each box there are four separate small boxes, and inside each of the small boxes there are three even smaller boxes, to determine how many boxes are there all together, the following calculation must be done:

3 + 3 x 4 + 3 x 4 x 3 = X

3 + 12 + 36 = X

51 = X

Therefore, there are 51 boxes all together.

The reproduction function for a sardine is f(p) = −0.0005p2 + 4p, where p and f(p) are in hundred metric tons. Find the populati
tensa zangetsu [6.8K]

Answer:

Population (p) = 4,000 hundred metric tons

Size of the yield (f(p)) = 8,000 hundred metric tons

Step-by-step explanation:

The population of sardines 'p', for which the derivate of the function f(p) is zero, is the population that gives the maximum sustainable yield:

f(p) = -0.0005p^2 + 4p\\\frac{df(p)}{dp}=-0.0010p+4\\-0.0010p+4 =0\\p=4,000

The size of the maximum sustainable yield is:

f(p) = -0.0005p^2 + 4p\\f(4,000) = -0.0005(4,000^2) + 4*4,000\\f(4,000) = 8,000

Population = 4,000 hundred metric tons

Size of the yield = 8,000 hundred metric tons

Your graphing the speed your car goes on the interstate from the time you enter the ramp until you arrive at the next exit ramp
inysia [295]

Answer:

1 minute on the x-axis; 10 mph on the y-axis

Step-by-step explanation:

The distance between exit ramps is less than 6 miles and since you are traveling at 70 mph on the highway you should get there in less than 5 mins, so the scale on the x-axis should be 1 minute. Since you have 10 tick marks on the y-axis and will be going at a speed of 70 mph at some point, the scale on the y-axis should be 10 mph (100 mph total). A good scale would be 1 minute on the x-axis; 10 mph on the y-axis.
