The diameter of a tire is 2.5 ft. Use this measurement to answer parts a and b. Show all work to receive full credit. A. Find the circumference of the tire.
B. About how many times will the tire have to rotate to travel 1 mile? (1 mile = 5,280 ft)
Answer:
A. The circumference of the tire is approximately 7.854 feet.
B. The tire rotates about 672 times to travel 1 mile.
Step-by-step explanation:
A. The circunference ([tex]s[/tex]), measured in feet, in terms of diameters is defined by the following formula:
[tex]s = \pi \cdot D[/tex] (1)
Where [tex]D[/tex] is the diameter of the tire, measured in feet.
If we know that [tex]D = 2.5\,ft[/tex], then the circunference of the tire is:
[tex]s = \pi\cdot (2.5\,ft)[/tex]
[tex]s \approx 7.854\,ft[/tex]
The circumference of the tire is approximately 7.854 feet.
B. The value found in A. represents the distance travelled by the tire per revolution. Then, the number of revolutions ([tex]n[/tex]), no unit, associated to the distance travelled is calculated by this expression:
[tex]n = \frac{s}{\pi\cdot D}[/tex] (2)
If we know that [tex]s = 5280\,ft[/tex] and [tex]D = 2.5\,ft[/tex], then the number of revolutions done by the tire to travel 1 mile is:
[tex]n = \frac{5280\,ft}{\pi\cdot (2.5\,ft)}[/tex]
[tex]n \approx 672.270[/tex]
The tire rotates about 672 times to travel 1 mile.
Original Price = ? Percent of Discount = 5% Sale Price = $57
Answer:
$60
Step-by-step explanation:
If it's 5% off, the sale price will be 95% of the original price.
you have [tex]0.95x = 57\\[/tex] where x is the original price
solving:
multiply both sides by 100
[tex]95x = 5700[/tex]
divide both sides by 95
[tex]x = 60[/tex]
The original price is $60
Can you find the y=mx+b?
Answer:
y=-2x+7
Step-by-step explanation:
Slope is y(2)-y(1)/x(2)-x(1)
I chose (1,5)(0,7) as my two points and got -2 as my slope
Then, I got (0,7) as my y-intercept because it was in the table.
So, the equation is y=-2x+7

Terry bought a sweater for$24 before tax he had a coupon for 1/4 off the sales tax rate was 6%. How much did terry pay for the sweater, including tax?
Answer: Terry paid $18.36 for the sweater.
Step-by-step explanation:
Given: Sales price of sweater = $24
Coupon states [tex]\dfrac14[/tex] off the sales, i.e. Terry will get [tex]\dfrac14\times24=\$6[/tex] discount.
Also, tax rate = 6%
Tax will be charged = 6% of Sales price of sweater
= 0.06 x 6
= $0.36
Now , Final amount for Terry = Sales price - discount +tax
= $(24-6+0.36)= $18.36
Hence, Terry paid $18.36 for the sweater.
Express in simplest radical form.

Madison and Tanisha went out to lunch. The bill came to $18.94. Madison knows that her lunch cost 9.72. How much did Tanisha's lunch cost?
Answer:
Tanisha's lunch cost $9.22.
Step-by-step explanation:
Given that,
Total bill = $18.94
Cost for Madison cost = $9.72
Total cost = Tanisha's lunch + Madison's lunch
18.94 = Tanisha's lunch + 9.72
Tanisha's lunch = 18.94 - 9.72
Tanisha's lunch = 9.22
So, Tanisha's lunch cost $9.22.
