Mathematics

Answer:

$15.5

Step-by-step explanation:

let a = price of one orchid plant

8 orchids would cost 8 x a = 8a

12 orchids would cost 12 x a = 12a

Let b = price of one lily plant

12 lilies would cost 12 x b = 12b

8 lilies would cost 8 x b = 8b

8a + 12b = 362 -- eqn 1

12a + 8b = 388 -- eqn 2

to solve, multiply equation 1 by 8 and equation 2 by 12

64a + 96b = 2896 equation 3

144a + 96b = 4656 equation 4

substract equation 4 from 3

80a = 1760

a = $22

Substitute for a in eqn 1 and solve for b

8(22) + 12b = 362

b = $15.5

which of the following could be side lenths of a right triangle? A.) 0.9cm, 1.2cm, 1.5cm B.) 0.9cm, 1.5 cm, 1.5cm C.) 0.9 cm, 1.
Gwar [14]

Answer:

The answer A

Step-by-step explanation:

B: You need a side that is longer than 2 equal sides. B is incorrect.

A: Try

9^2 + 12^2 = 15^2 if that works, A will work.

81 + 144 = 225

This works. I used these numbers because they were easier to see.

0.9^2 + 1.2^2 = 1.5^2

0.81 + 1.44 = 2.25

2.25 = 2.25

That is the answer A

But we have to check the  other two.

C:

0.9^2 = 0.81

1.2^2 = 1.44

1.8^2 = 3.24   This won't work. 3.24 is just too big.

D:

0.9^2 = 0.81

0.6^2 = 0.36

1.5^2 = 2.25   It's too far away.

The circle shows the radius of 12mm what is the circumference
gulaghasi [49]

Answer:

24π or about 75.4 mm

Step-by-step explanation:

The circumference of a circle is denoted by C = 2πr, where r is the radius.

Here, we see that r = 12, so plugging this in:

C = 2πr

C = 2π * 12 = 24π ≈ 75.4 mm

The answer is thus 24π or about 75.4 mm.
