The time interval for the mechanic for this job is at least 2 hours and 30 minutes or at most 3 hours and 30 minutes.
What is at least and at most concept ?At least means lower limit of a given contrast and at most means higher limit of a given contrast.
According to the given question parts for an automobile repair cost 173 dollars and the mechanic charges 32 dollars per hour.
Given the person receives a cost of at least 253 dollars.
∴ The mechanic's total rate is ( 253 - 173 ) dollars which is = 80 dollars.
Also given the mechanic charges 32 dollars per hour so the time mechanic work for is at least (80/32) hours which is = 2.5 hours or 2 hours and 30 minutes.
In the later case when the owner receives a bill of 285 dollars the total rate of mechanic is
= ( 285 - 173 ) dollars.
= 112 dollars.
So, the mechanic have worked for (112/32) hours which is
= 3.5 hours or 3 hours and 30 minutes.

the cost of fun for kids magazine for x number of months is shown below
The cost (C) of another magazine, Family Fun, for x number of months is
given by C-1.99x.
The cost of another magazine, Kidz Comics, is $1.85 for each month. The
annual subscription includes a delivery charge of $10, while the annual
subscription for Fun for kids and Family Fun has no such extra charge
Which annual subscription costs the most?
Answer:
Kidz comic costs the most
Step-by-step explanation:
Given
Family Fun
[tex]C(x) = 1.99x[/tex]
Kidz Comics
[tex]m = 1.85[/tex] --- monthly rate
[tex]b = 10[/tex] --- delivery charge
Required
Which is more expensive
A linear function is represented as:
[tex]f(x) = mx + b[/tex]
Where
[tex]m = rate[/tex]
[tex]b = y\ intercept[/tex] --- i.e. the base charge
So, for Kidz comic; We have:
[tex]f(x) = mx + b[/tex]
[tex]C(x) = 1.85x + 10[/tex]
To calculate the annual cost, we set x = 12; i.e. 12 months.
So, we have:
[tex]C(x) = 1.99x[/tex] ---- Family Fun
[tex]C(12) = 1.99 * 12[/tex]
[tex]C(12) = 23.88[/tex]
[tex]C(x) = 1.85x + 10[/tex] --- Kidz comic
[tex]C(12) = 1.85*12 + 10[/tex]
[tex]C(12) = 22.2 + 10[/tex]
[tex]C(12) = 32.2[/tex]
By comparison
[tex]32.2 > 23.88[/tex]
Hence, Kidz comic is more expensive
12 yd. 3 yd. 9 yd. 6 yd. Find the area of the shape. 39 square yards 56 square yards 72 square yards 106 square yards
It it was a whole rectangle: 12 x 9 = 108 square yards

Step-by-step explanation:
1) find the slope of the given line
slope = (-a/b) = (-8/4) = -2
two parallel lines have the same slope
A : correct
B : (-a/b) = -16/8 = -2 (correct)
C : correct
D : wrong (2 is different from -2)

Elijah bought a chest of drawers originally priced at $50.40 but on sale for 40% off. After 6.25% sales tax, what was the total cost
Answer:
$32.13
Step-by-step explanation:
IXL
The total cost will be;
⇒ $32.05
What is mean by Percentage?
A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.
Given that;
Elijah bought a chest of drawers originally priced at $50.40 but on sale for 40% off.
Now,
Since, Elijah bought a chest of drawers originally priced at $50.40 but on sale for 40% off.
Hence, The sale price = 40% of $50.60
= 40/100 × $50.60
= $20.24
Thus, The price chest of drawers become = $50.40 - $20.24
= $30.16
Since, The sales tax = 6.25%
Hence, The sales price = 6.25% of $30.16
= 6.25/100 x 30.16
= $1.89
Thus, The total cost = $30.16 + $1.89
= $32.05
Therefore, The total cost will be;
⇒ $32.05

A rappelling rope used for outdoor programs, rescue and industrial work, can safely support a weight "W" (in pounds) provided, where "d" is the rope's diameter (in inches). Determine the diameter of rope that would be needed to support a weight of at least 5,500 pounds.
Answer:
D = ( d * 5500 ) / W
Step-by-step explanation:
Diameter of rope " d " supports "w" weight
i.e. d = W
d ( inches ) = W ( pounds )
? ( inches ) = 5500 pounds
The Unknown diameter D ( ? ) = d * 5500 / W
