A manufacturer determines that the cost of making a computer component is $3.171717. Write the cost as a fraction and as a mixed number.
Answer:
Step-by-step explanation:
100y = 317.17171717171717 ....
y = 3.17171717171717 .... subtract
99y = 314

Line l in the xy-plane is perpendicular to the line
with equation x = 2. What is the slope of line l?
The slope of line L is 0. Then the equation of the line L in the xy-plane will be y = 0.
What is the equation of a perpendicular line?Let the equation of the line be ax + by + c = 0. Then the equation of the perpendicular line that is perpendicular to the line ax + by + c = 0 is given as bx - ay + d = 0. If the slope of the line is m, then the slope of the perpendicular line will be negative 1/m.
The equation of the line is x = 2. Then the slope of the equation will be given as,
m = ∞
The slope of the perpendicular line is calculated as,
⇒ -1/m
⇒ -1/∞
⇒ 0
The slope of line L is 0. Then the equation of the line L in the xy-plane will be y = 0.

The cost to make a Nike shoe is $20 USD and the store wants to make a profit of 75% of the cost price.
If the sales tax is 5%, what is the price of a shoe after tax?
so 75%of 20 is 15.00
and then we 20.00+15.00= 35.00
plus sales tax of 5%
so I got 36.75$ after taxs

what must be added to 2x^2 - 5x - 12 in order to get 7x^2 - x - 18
Answer:
5x^2 +4x -6
Step-by-step explanation:
that is the answer
yep
Answer:
5x² + 4x - 6
Step-by-step explanation:
Subtract 2x² - 5x - 12 from 7x² - x - 18 , that is the opposite operation, that is
7x² - x - 18 - (2x² - 5x - 12) ← distribute parenthesis by - 1
= 7x² - x - 18 - 2x² + 5x + 12 ← collect like terms
= 5x² + 4x - 6

Shawna and her best friend Keisha go shopping.
The function p(x) = 3x^4 + 2x^3 − 4x^2 + 21 represents how much money each girl spent based on the number of hours they were shopping. If Shawna and Keisha each go shopping for 2 hours, how much money did they spend together?
$37
$69
$101

Answer:
138
Step-by-step explanation:
p(x) = 3x^4 + 2x^3 − 4x^2 + 21
Let x = 2
p(2) = 3*(2)^4 + 2*(2)^3 − 4*(2)^2 + 21
= 3*16+2*8-4*4+21
=48+16-16+21

There are 1175 calories total in a Big Mac, a Grilled Chicken Sandwich and a 6-piece chicken nugget meal.
A 6-piece chicken nugget meal has half the calories of the Big Mac. The Grilled Chicken Sandwich has 200 less
calories than the Big Mac. How many calories are in each of the three food items?
Big Mac has 550 calories
Chicken Nugget has 275 calories
Grilled Chicken Sandwich has 350 calories
Total number of calories = 1175
Let the number of calories in Big Mac = x
Since the 6-piece chicken nugget meal has half the calories of the Big Mac. Therefore, the number of calories in the chicken nugget = 1/2 × x = 0.5x
Since the Grilled Chicken Sandwich has 200 less calories than the Big Mac. This will be: = x - 200
To calculate the number of calories in each food goes thus:
x + 0.5x + x - 200 = 1175
Collect like terms
x + 0.5x + x = 1175 + 200
2.5x = 1375
Divide by 2.5
2.5x/2.5 = 1375/2.5
x = 550
Big Mac has 550 calories
Chicken nugget will have:
= 0.5x = 0.5 × 550 = 275 calories
Grilled Chicken Sandwich will be:
= x - 200
= 550 - 200
= 350 calories
