Answer:
Option D)R: {0 ≤ y ≤ 360}; The range represents the number of miles the car can travel
Step-by-step explanation:
The table in the attached figure
Let
x -----> the amount of gas used in gallons (independent variable)
y ----> the number of miles the car can travel (dependent variable)
In this problem
The domain is the interval -----> [0,12]
The range is the interval ----> [0,360]
You just need two points to graph a line.
When x = 1
y - 4 = -1/4(1 - 5)
y - 4 = -1/4(-4)
y - 4 = 4/4
y - 4 = 1
y = 5
So, we have our first point, (1,5)
When x = 2
y - 4 = -1/4(2 - 5)
y - 4 = -1/4(-3)
y - 4 = 3/4
y = 4 3/4
Now we have the point (2, 4 3/4)
Now just run a line through the two points and you're done!
Answer:
the first option
Step-by-step explanation:
solution:
distance: d=1/4 lc (because is a quarter of a circle)
length of the circumference: lc=2 pi r
pi: constant=3.14
radius of the circle: r=80 feet
replacing pi and r in the formula of lc:
lc=2 pi r
lc=2 (3.14) (80 feet)
lc=502.4 feet
replacing lc in the formula of d:
d=1/4 lc
d=1/4 (502.4 feet)
d=502.4/4 feet
d=125.6 feet
Answer: $31.45
Step-by-step explanation:
Given : The price of a pair of pants is $29.95.
The sales tax is 5% = 0.05
Required formula :
Total cost = Price + sales tax percent × Price
Total cost= Price (1+Sales tax percent)
i.e. Total cost of the pair of pants= 29.95 (1+0.05) =29.95(1.05)=31.4475 ≈ 31.45
Hence, the total cost of the pair of pants = $31.45
What you do is stack the fractions and subtract 9-3 and you get 6 and bring down the 8 and subtract 5-3 and you get 6 6/8
