Answer:
13 square units
Step-by-step explanation:
You <em>could</em> calculate the length of each side using Pythagorean theorem, then use Heron's formula to find the area. But there's an easier way: find the area of the rectangle that contains the triangle, and subtract the areas of the smaller triangles in the corners.
The area of the rectangle is 4 × 7 = 28.
The area of the upper left triangle is ½(2)(4) = 4.
The area of the upper right triangle is ½(3)(5) = 7.5.
The area of the lower right triangle is ½(1)(7) = 3.5.
So the area of the triangle is:
28 − 4 − 7.5 − 3.5 = 13
The total cost of the meal is $30.02
Step-by-step explanation:
Given,
Cost of meal = $24.62
Tax = 6%
Tax amount = 6% of cost of meal
Cost after sales tax = 24.62+1.48 = $26.10
Tip = 15%
Tip amount = 15% of cost after sales tax
Total cost of meal = Cost after sales tax + Tip amount
Total cost of meal = 26.10+3.92 = $30.02
The total cost of the meal is $30.02

Answer:
1 median=60.3
2 missing number=38
Step-by-step explanation:
1 45+55+76+y+88+54/6
316+y/6=63.6
316+x381.6
x=381.6-316=65.6
2M4 =63
60-62+92+x/4=63
214+x=252
x=252-214
=38
