2) The Rodriguez family went to dinner at Pasta Palace. Mr. Rodriguez ordered ameal for $16.25; Mrs. Rodriguez ordered a meal for $19.50; the three children
ordered individual pizzas for $6.99 each. The tax rate is 8.75% and the family
wants to leave an 18% tip applied after the tax. How do they leave in all
including tax and tip? Helpppp pleaseee!!! I will give brainlest!!!! With explanation
Answers
Explanation:
$16.25+$19.50+(6.99*3)
=$56.72 in total without tax or tip
56.72*0.0875
=(4.963 but in money form)$4.96 is the how much tax was
56.72+4.96
=$61.68 is the total amount including tax
61.68*.18
=$11.10 is how much tip was
61.68+11.10
= $72.78 is the total amount including tax and tip

gravity on earth :g=9.81 m/s²
9.81/2≈4.9
Answer 1
2)
h(t)=-4.9*t²+20*t+10
To hit the ground ht(t)=0
==> -4.9*t²+20*t+10=0

y = 3x + 2
Answers
Answer:
y = -1/3x +6
Step-by-step explanation:
You want the equation of the line through (3, 5)perpendicular to the line y = 3x +2.
Perpendicular line
The given equation is in slope-intercept form. This lets us identify its slope as 3.
y = mx + b . . . . . . line with slope m and y-intercept b
y = 3x +2 . . . . . . . line with slope 3 and y-intercept 2
The perpendicular line will have a slope that is the opposite reciprocal of this:
m = -1/3 . . . . slope of the perpendicular line
Point-slope form
The equation for a line with slope m through point (h, k) is ...
y -k = m(x -h)
The equation for a line with slope -1/3 through point (3, 5) is ...
y -5 = -1/3(x -3)
Slope-intercept form
Solving for y gives us ...
y = -1/3x +1 +5 . . . . . eliminate parentheses, add 5
y = -1/3x +6 . . . . . equation of the desired line

Part B: How many homes does Neighborhood A have after 5 years? How many does Neighborhood B have after the same number of years? (2 points)
Part C: After approximately how many years is the number of homes in Neighborhood A and Neighborhood B the same? Justify your answer mathematically. (4 points)
Answers
Neighborhood B: 45 homes and increases by 3 per year.
N.A = 30 (1.20)^t
N.B = 45 + 3(t)
t = 5
N.A = 30(1.20)^5 = 30(2.48832) = 74.65 or 75
N.B = 45 + 3(5) = 45 + 15 = 60
