Answer: Percentage of sales tax will be 5%.
Step-by-step explanation:
Since we have given that
Original amount of a surfboard = $240
Sales tax on a surfboard = $12
So, Percentage of sales tax will be
Hence, Percentage of sales tax will be 5%.
To solve this problem you must apply the proccedure shown below:
1. The vertex i at <span>(0, 36) and a focus at (0, 39), then you have:
a=36
a^2=1296
2. The directrix is:
y=a^2=c
c=39
y=1296/39
</span>y=432/13<span>
Therefore, the answer is the option D, which is: </span><span>D. y=± 432/13</span>
Answer:
$61.69 You take the 15.5 and take off the .5 to begin with so you start with 15 multiply it by 3.98 to get 59.7 then you take 3.98 divide it by 2 because the .5 is the same thing as 1/2 then you get 1.99 then you add it to your 59.7 to get 61.69 and thats your answer. Hope this helps :)
Answer:
<u><em>Katie runs fastest </em></u>
Step-by-step explanation:
For us to know the person who runs fastest, we need to calculate their speed in feet per seconds (ft/s)
For Tony; his speed is 12ft/s
For Katie;
Katie runs 450 feet in 30seconds;
450 feet = 30 secs
x = 1 sec
Cross multiply
30x = 450
x = 450/30
x = 15ft
Hence Katie runs 15ft/s
For Frank;
Frank ran 1 mile per 577secs
1 mile = 5280feeet
This mean that he ran 5280feet in 577 secs
5280feet = 577secs
y = 1 secs
cross multiply;
577y = 5280
y = 5280/577
y = 9.15ft/s
Hence Frank ran 9.15ft/s
For Adam;'
If Adam ran 880 ft in 1 minutes, this means he ran 880ft in 60secs
880 ft = 60secs
z = 1sec
Cross multiply
60z = 880
z = 880/60
z = 14.67ft/s
Hence Adam ran 14.67ft/s
<em>From the value of their speed, we can see that </em><u><em>Katie runs fastest </em></u><em>with a speed of 15ft/s</em>
Brandon's rectangle:
Length = 8.75 x 1.5 = 13.125 inches
Width = 6 x 1.5 = 9 inches
If you need the area and perimeter then here:
Area = 13.125 x 9 = 118.123 inches square or sq in.
Perimeter = 2 x (13.125+9) = 44.25 in
