Step-by-step explanation:
160 miles = 20 gallons
400 miles = x gallons
160 × x = 20 × 400
x = 8, 000/160
x = 50 gallons
To find the mean add up all the numbers given then divide your answer by how many numbers there are.
for ex: 1,2,3,4,5
1+2+3+4+5= 15
15 divided by 5 = 3
so the mean is 3
Answer:
d = 126, z = 28
Step-by-step explanation:
The angle with the variable is diagonal from the 105 degree angle. In this case, that means that they are equivalent. So, 105+21 = 126. d = 126 :)

Answer: 126.5 square cm</h3>
===================================================
Explanation:
Check out the diagram below. I've drawn a horizontal line to split the orange region into two parts: a triangle on top and a rectangle down below.
The triangle has base 11 cm and height 7 cm. The area is base*height/2 = 11*7/2 = 77/2 = 38.5 sq cm.
The rectangle has area 11*8 = 88 sq cm.
The total area of the entire orange figure is 38.5+88 = 126.5 square cm
