Answer:
- The equation StartFraction 1 over 8 EndFraction (x + 16) = StartFraction 76 over 8 EndFraction represents the situation, where x is the food bill.
- The solution x = 60 represents the total food bill.
Step-by-step explanation:
Hi, to answer this question we have to write an equation:
The food bill (x) plus the tip (16) ;divided by the number of friends (8) , must be equal to the total amount spent (76) divided by the number of friends (8):
Mathematically speaking:
(x+16) /8 = 76/8
(x+16) /8 = 9.5
(x+16) = 9.5 (8)
x+16 = 76
x = 76-16
x= 60 (food bill)
So, the correct options are:
- The equation StartFraction 1 over 8 EndFraction (x + 16) = StartFraction 76 over 8 EndFraction represents the situation, where x is the food bill.
(1/8 (x+16) =76/8)
- The solution x = 60 represents the total food bill.
Answer:
33 feet
Step-by-step explanation:
Use SOHCAHTOA to determine which trigonometric function to use:
sin(65)=30/x
sin(65)x=30
x=30/sin(65)
x=33.1
So the length of the ladder rounded to the nearest foot is 33 feet

Answer:
24
Step-by-step explanation:
Split the shape into 2 so you get a triangle and a rectangle.
Find area of triangle:
1/2 x a x b = 1/2 x 3 x 4
= 6 square feet
Find area of rectangle:
b x h = 6 x 3
= 18
Add both together
18 + 6 = 24
