Answer:

See below in bold.

Step-by-step explanation:

Let t be the number of tulips you buy and r be the number of rose bushes.

The system is:

t + r = 13

4t + 10r = 100

Solving:

4t + 10r = 100

t + r = 13 Multiply this by 4:

4t + 4r = 52 Subtract this from the first equation:

0 + 6r = 48

r = 8.

Now substitute for r in t + r = 13:

t + 8 = 13

t = 5.

To buy 13 plants and spend $100 you need to buy 5 tulips and 6 rose bushes.

<h2>Answer:</h2>

<u>Sample space</u> = {10, 11, 12, 13, 14, 20, 21, 22, 23, 24, 30, 31, 32, 33, 34, 40, 41, 42, 43, 44}

∴ n(S) = 20 .

[i] <u>Let A be the event that the number so formed is a prime number</u>.

∴ A = {11,13,23,31,41,43}

∴ n(A) = 6

So, P(A) = n(A)/n(S) = 6/20

∴ P(A) = 3/10.

[ii] <u>Let B be the event that the number so formed is a multiple of 4</u>.

∴ B = {12,20,24,32,40,44}

∴ n(B) = 6

So, P(B) = n(B)/n(S) = 6/20

∴ P(B) = 3/10.

[iii] <u>Let C be the event that the number so formed is a multiple of 11</u>.

∴ C = {11,22,33,44}

∴ n(C) = 4

So, P(C) = n(C)/n(S) = 4/20

∴ P(C) = 1/5.

Since the radius of the semi circle is 10 cm then the diameter is 20 cm, when folded, its circumference is now 20, given the circumference find the radius of the cone. i guess

Volume = 1/3 πr2 (l2﹣r2)1/2

circumference = 20 cm = πD

D=6.363636364

Radius = 6.363636364/2 = 3.181818182

l = 10

vol = 100.51cm3

curved s.a = πrl
