Answer:

To find the height of a cube you simply need to know the length of the sides of a cube.

Step-by-step explanation:

All sides of a cube are equal because it is made up of squares. If a cube has a length of 3 cm, then it will also have a height of 3 cm.

Mrs. Kelly creates a garden. She buys 15 flowers and 3 bushes for a total cost of $160.32. Each bush costs $11.50 more than each

Brut [27]

The cost of each bush is $ 18.49

<h3><u>Solution:</u></h3>

Let "f" be the cost of each flower

Let "b" be the cost of each bush

<em><u>Given that Mrs. Kelly buys 15 flowers and 3 bushes for a total cost of $160.32</u></em>

15 flowers x cost of each flower + 3 bushes x cost of each bush = 160.32

$15 \times f + 3 \times b = 160.32$

15f + 3b = 160.32 ----- eqn 1

<em><u>Each bush costs $11.50 more than each flower</u></em>

Cost of each bush = 11.50 + cost of each flower

b = 11.50 + f ------ eqn 2

<u><em>Let us solve eqn 1 and eqn 2 to find values of "b" and "f"</em></u>

Substitute eqn 2 in eqn 1

15f + 3(11.50 + f) = 160.32

15f + 34.5 + 3f = 160.32

18f = 160.32 - 34.5

18f = 125.82

Substitute f = 6.99 in eqn 2

b = 11.50 + 6.99 = 18.49

Thus the cost of each bush is $ 18.49

How many 5 card hands contain exactly 2 queens

iris [78.8K]

There are 4 queens in the deck, hence (4 choose 2) = 4!/(2! (4-2)!) = 6 ways of getting 2 queens.

The other 3 cards in the deck can be any of the remaining 48 non-queens; there are (48 choose 3) = 48!/(3! (48-3)!) = 17,296 ways of getting these.

In total, there are (4 choose 2)*(48 choose 3) = 103,776 total possible hands.

Carlos is spreading mulch in a circle on top of an area where he has planted some seeds. He has enough mulch to cover an area th

goldenfox [79]

<span>To find the circumference, the area first needs to be found to discover the radius. Area equals (r^2) multiplied by pi, or approximately 3.14. In this case, 12.5/3.14 gives a radius^2 of 3.98 feet. The square root of 3.98 is 1.99 feet. Using the radius, the diameter and circumference can now be found. The diameter is (2r), which would also be 3.98 feet in this case. 3.98 * 3.14 gives a circumference of 12.4972 feet.</span>
