PLEASE HELP! ITS DUE AT 12! ITS 2 QUESTIONS! WILL MARK BRAINLIEST 1: Rick buys a remote control car to resell. He pays $28 in applies a mark up of 10%. what is his reselling price?

write an expression:
find the retail price:

2: A bicycle shop marks down each bicycle selling price by 30% for a holiday sell. what is the sale price of a bicycle that regularly cost $150?

write an expression:
find the sale price:

<3

1) The first expression is found by using the formula retail price = original cost + markup. If p is the original price, then the expression is p + 0.1p. The second expression can be found by simplifying the first expression. This gives 1.1p

b) Substituting p = 28 into the second expression gives 1.1(28) = 30.8 so the selling price is $30.80

Step-by-step explanation:

i don't know number 2 hope that helps

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.

p ÷ r = tan(x)

step-by-step explanation:

given that there is a figure below shows a right triangle: a right triangle is shown with hypotenuse equal to q units and the length of the legs equal to p units and r units.

graph is missing so i will create the graph as per given information.

the angle between the legs having lengths p units and q units is y degrees. the angle between the legs having lengths r units and q units is x degrees.

now we need to find about what is p ÷ r equal to.

so we can use trigonometric ratio tan(x)=[altitude]/[base] to find the value of p ÷ r, because p is the altitude and r is the base.

p ÷ r=tan(x)

hence final answer is p ÷ r=tan(x).
