Answer:

See below.

Step-by-step explanation:

There are about 30 days in each month. with that in mind, we can say Species A grows about 3cm/30days and Species B grows 8cm/30days. As a function of days "d" we can say Species A grows at a rate of (3/30)d and Species B at (8/30)d.

*Notice how when d = 30, it reflects one month of growth for each.

And since each plant had some height already, we can write two equations like this:

  • Species A; H(d) = (1/10)d + 25
  • Species B; H(d) = (8/30)d + 10

*Just in case you didn't see it, (3/30) can be reduced to (1/10); which is what I did above.

Find the sides of a rectangle having area 125 square units if the sides are in the ratio 5:3.
tatiyna

For this case we have the following data:

Area of the rectangle, A = 125

Relationship of the sides 5: 3

By definition, the area of a rectangle is given by:

A = a * b

Where

  • a: is the longest side.
  • b: it is the side of least length.

If the sides have a 5: 3 ratio, it means:

\frac{a}{b}=\frac{5}{3}

a=\frac{5}{3}b

Substituting in the formula of the area, we have:

125 =a * b\\

125=\frac{5}{3}b*b

Clearing b:

3 * 125 = 5 * b ^ 2

\frac{375}{5}= b ^ 2

75 = b ^ 2

b =\sqrt{75}b = 8.7 units

Substituting and clearing:

125 = a * 8.7

a =\frac{125}{8.7}

a = 14.4units

So, the sides are:

a = 14.4units

b = 8.7units

Answer:

a = 14.4units

b = 8.7units

Mike put 400 baseballs into 10 trash bins. He put the same number of baseballs in each bin. He took 5 trash bins of baseballs to
leva [86]

Answer:

200 baseballs

Step-by-step explanation:

Mike put 400 baseballs into 10 trash bins. He put the same number of baseballs in each bin.

Hence, the number of baseballs he puts in each bin is:

400 / 10 = 40 baseballs

He took 5 trash bins of baseballs. This means that the number of baseballs he took is:

5 * 40 = 200 baseballs

He took 200 baseballs.
