Heidi left a 15% tip of $6.60 on a meal. What was the cost of the meal before the tip? What was the total cost of the meal including the tip?
The cost of the meal before the tip was $
nothing.

Answers and Step-by-step explanations:

We know that 15% of the meal was $6.60, so we can write this as:

15% * m = 6.60, where m is the cost of the meal before the tip

0.15 * m = 6.60

m = 44

So, the cost of the meal before the tip was $44.

The total cost of the meal and the tip will just be the sum of the value of m and the value of the tip: 44 + 6.6 = $50.60.

Hope this helps!

$44

$50.6

Step-by-step explanation:

15% : $6.60

100% : X

X/100 = 6.6/15

X = 44

Total cost

44 + 6.6

50.6

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.

step-by-step explanation:

mean or average is 40.6
