Answer:
The total cost of the helicopter = $26.5
The cost of lithium battery = $5.
The amount of sales tax = $1.5
Step-by-step explanation:
We have been given that a radio-controlled helicopter sells for $20, but needs a lithium battery that costs 25% of that price.
We can find the price of battery by finding 25% of 20.
Therefore, the cost of lithium battery is $5.
Now let us find the sales tax on the cost of helicopter and lithium battery.
Therefore, the total sales tax will be $1.5.
We can find the total cost of helicopter by adding the cost of helicopter, cost of lithium battery and total amount of sales tax.
Therefore, the total cost of helicopter will be $26.5.
Answer:
176$
Step-by-step explanation:
do 48 divided by 3 then times by 11
To graph a line, first, we need to plot out values. Let’s find a few: if y is 2, -x would be 2-6, and x would be 4. If y is -2, x would be 8.
Now, all you have to do is put a few more of those points on a line graph and connect them.
Good luck!
Answer:
a. 
b. 
Step-by-step explanation:
a. Radius of semicircle (r) = r
Diameter of semicircle (d) = 2r
Length of rectangle (l) = 2*diameter of semicircle = 2*2r = 4r
Distance around the track (p) = circumference of circle + 2(l)
Note: the two semicircles of the track = 1 full circle
Circumference of full circle = πd = π*2r = 2πr
Distance around the track:
p = 2πr + 2(4r)
p = 2πr + 8r
b. Rewriting the formula to make radius, r, the subject of the formula in terms of distance around the track.
Factor out r
Divide both sides by (2π + 8)
