first transform feet into inches 4.5 feet = 48.5 inches; 5.5 feet = 60.5 inches;
then get the area in inches : 48.5 x 60.5 = 2934.25 inches; the area of one patch is 18 x 24 = 432 inches
so now divide the area of the desktop by the area of one patch
2934.25 / 432 = 6.7 so she needs 7 patches
Answer:
The answer is 3054.8
Step-by-step explanation:
V = 4/3 × 22/7 × 9 × 9 × 9
V = 4 × 22/7 × 3 × 81
V = 4 × 22 × 243/7
V = 21384/7
V = 3054.8
Thus, The answer is 3054.8
The distance the tip travels is
2π·(40 m) = 80π m
Then its speed is
(80π m)/(10 s) = 8π m/2 ≈ 25.1 m/s
There are 7,315 different combinations, thus, the correct option is c
<h3>
How many combinations are there?</h3>
If we have a set of N elements, the number of different combinations of K elements (such that K ≤ N) of these N elements that we can make is:
In this case we have K = 4 and N = 22, replacing that, we get:
So there are 7,315 different combinations, thus, the correct option is c.

Answer:
Total tickets = 70
Total cost = $550
Adult's ticket = $9
Child's ticket = $5
Difference = 9 - 5 = $4
Assume all 70 are child's tickets
5 x 70 = 350
But the total cost was 550
550 - 350 = $200
The $200 must have come from Adult's tickets, which has a difference of $4.
200 ÷ 4 = 50
So there are 50 adult's tickets.
70 - 50 = 20
And there are 20 child's tickets.
Hope this helps - Itz.Jordan
