Answer:
Period =
The ferris wheel will complete one round in 40 seconds.
Step-by-step explanation:
We are given the function representing the height of the wheel by,
where t = time in minutes.
Now, we know that if a function f(x) has period P, then a×f(bx+c)+d will have the period .
Since, the function has period , thus the function h will have period i.e. .
Therefore, the period of this function is .
Now, since the period is minutes i.e 40 seconds.
Hence, we get that the ferris wheel will complete one round in 40 seconds.
Answer: The value of q is exactly 7
------------------------------------
Explanation:
L = 16 is the length
W = 3 is the width
H = q is the unknown height
S = 362 is the surface area
We'll use the formula
S = 2*(L*W+W*H+L*H)
which is the surface area formula for any rectangular block
So plug in the given info and solve for q
S = 2*(L*W+W*H+L*H)
362 = 2*(16*3+3*q+16*q)
362 = 2*(48+3q+16q)
362 = 2*(48+19q)
362/2 = 2*(48+19q)/2 ... divide both sides by 2
181 = 48+19q
48+19q = 181
19q+48 = 181
19q+48-48 = 181-48 .... subtract 48 from both sides
19q = 133
19q/19 = 133/19 .... divide both sides by 19
q = 7
Given the markup of 75%, the selling price of the item became:
Cost×(1+Markup)=selling price
the initial price of the house will therefore be:
C×(1+0.75)=350
1.75C=350
C=350/1.75
C=$200
therefore the initial selling price was $200. Given that after the markup price was later reduced by 20%, the new price became:
80/100×350
=$280
If the price was later reduced by 30% the new price was:
70/100×280
=$196
From this final price we see that if the original price was $200 and the selling price is now $196, then the item is actually selling at lose.<span />
Answer:
1/2
Step-by-step explanation:
I think so im not sure tho so sorry if its incorrect
Answer:
28.5
Step-by-step explanation:
1/2 is 0.5 as a decimal.
That would mean that 28 1/2 is the same as 28.5.
Hope this helps! Brainliest would be really appreciated!
