The amount without a tip = B
Tip amount= .21B
Total amount = B+ .21B
Answer:
This is not a direct variation
Step-by-step explanation:
if 12 dollars for 6 bagels is true then each bagel is $2
if 9 dollars for 24 bagels then each bagel is $0.38
Answer:
√(209)
Step-by-step explanation:
Since <B is a right angle, AC is the hypotenuse and AB and BC are legs.
(AB)² + (BC)² = (AC)²
(4 mm)² + (BC)² = (15 mm)²
16 mm² + (BC)² = 225 mm²
(BC)² = 209 mm²
BC = √(209) mm
Answer:
CosA/CosB =1
CosA = Adjacent side/Hypotenuse
=AC/AB = 3/4.24
Cos B = Adjacent side/Hypotenuse
= BC/AB = 3/4.24
CosA/CosB = (3/4.24)/(3/4.24) = 1
The value of CosA/CosB = 1
