Add the total bills:
23.59 + 40.65 + 30.50 + 15.68 = 110.42
Divide his tips by the total bills to get the rate of the tips
17.67 ÷ 110.42 = 0.16
0.16 x 100% = 16%
His tips were 16% of the bills.
To check:
23.59 x 16% = 3.7744
40.65 x 16% = 6.504
30.50 x 16% = 4.88
15.68 x 16% = <u>2.5088</u>
total tips 17.6672 rounded off to 17.67

Answer:
Step-by-step explanation:
Triangle ABC is a 45-45-90 right triangle. That means that segment BC also measures 10.
The big triangle as a whole is a 30-60-90. The side length across from the 30 degree angle is 10, so the whole length of BD is 10√3. However, since we already have the length of BC as 10, then segment CD measures
10√3 -10 which is 7.32
Answer:
y=-1/8y+1
Step-by-step explanation:
flip the equation, then add -8 to both sides to cancel out the +8 on the left, then divide sides by -8Let's solve for x.
y=−8x+8
Step 1: Flip the equation.
−8x+8=y
Step 2: Add -8 to both sides.
−8x+8+−8=y+−8
−8x=y−8
Step 3: Divide both sides by -8.
