When Ms. Perez has excellent service at a restaurant, the amount she leaves for a tip t is at least 20% of the cost of the meal
c. Write a model representing the amount of the tip.
1 answer:
Answer:
t ≥ 0.2c
Step-by-step explanation:
Her tip is at least 20% of the cost of the meal, so her tip is greater than or equal to 20% of the cost of the meal
tip ≥ 20% of the cost of the meal
t ≥ 20% of c
Another way of writing "20% of c" is multiplying the two values, so we have
20% of c = 20% * c
t ≥ 20% * c
To convert from a percentage to a decimal, we can divide the percentage by 100. Here, we have
20% = 0.2
t ≥ 0.2 * c

X=36
Step-by-step explanation:
90-54=36
Right angle 90 subtract 54
The missing angle x is 36
You can use the formula y1-y2=m(x1-x2)
to find m, you just do (y2-y1)/(x2-x1) so....
(115-80)/(80-40)= 35/40= 7/8
then plug it into the point slope equation:
y-115=7/8(x-80)
y-115=7/8x-70
y= 7/8 x + 45
