The total tax for the tickets and snacks was $3.96. They split all the costs evenly. How much did each girl pay? A. Step 1: Add $30.90 and $8.50. Step 2: Add the tax to that amount. Step 3: Divide by 3. B. Step 1: Calculate the price of 1 ticket. Step 2: Divide the total tax by 3. Step 3: Add the amounts from Steps 1 and 2 to $8.50. C. Step 1: Add the price of the tickets and the amount spent on food. Step 2: Add the amount of the tax. Step 3: Divide that total by 2.

Answers

30.90 + 8.50 + 3.96 = 43.36 (total cost)

If they are all splitting it evenly then divide by total ammount of people

43.36 / 3 = 14.45 each

The answer is A

Are the equations a/b=c/d and ad=bc equivalent? Explain.

Answers

Step-by-step explanation:

The relation given is a/b = c/d, if we cross multiply we will get ad = bc which we got from the first relation only. Let's take an example and assign a,b,c,d some numbers.

We know, 1/2 = 3/6 (equivalent fractions). Then a = 1, b = 2, c = 3, d = 6. Now put these values into the 2nd relation,

  • ad = 1 * 6 = 6
  • bc = 2 * 3 = 6

ad = bc relation is satisfied. Hence the equations a/b = c/d and ad = bc equivalent.

A particular beach is eroding at a rate of 4 centimeters per year. A realtor converts this rate to millimeters per day. Which expression, when evaluated, results in the correct units and numerical value?

Answers

Answer:

0.11mm/day

Step-by-step explanation:

We are given that

A particular is eroding at the rate=4 cm/ year

We have to convert this rate on milimeters per day.

We know that

1 year=365 days

1 cm=10 mm

Rate=(4* 10)/(365)

Rate=0.1096=0.11 mm/day

Answer:0.11 mm/day
4 cm/year * 10mm/cm * 1year/365day ≈ 0.11 mm/day
