When new, a standard tire has 10/32 inches of tread. When only 2/32 inches of tread remains, the tire needs to be replaced. If t

san4es73 [151]

Answer:

$\frac{1}{160} \ inches$

Step-by-step explanation:

The computation of the thickness of tire rubber for every lost 1,000 driven is shown below:

Data provided in the question

Inches of tread = $\frac{10}{23}$

In case of replaced = $\frac{2}{3}$

Based on the above information

Now in 40,000 miles, the ratio is

$= \frac{10 - 2}{32} \\\\ = \frac{1}{4}$

And for every 1,000 miles driven, the thickness is

$= \frac{1}{4 \times 40,000} \times 1,000 \\\\ = \frac{1}{160} \ inches$

hence, the thickness of tire rubber is $\frac{1}{160} \ inches$

Find cosx if sinx cotx =0.5

Arada [10]

Answer:

cos x = 0.5

Step-by-step explanation:

Using the trigonometric identity

cot x = $\frac{cosx}{sinx}$

Given

sin x cot x = 0.5, then

sin x × $\frac{cosx}{sinx}$ = 0.5 ← cancel sin x on numerator/ denominator

cos x = 0.5

Kristen needs to earn $320 in commission this week. She earns 8%

muminat

She needs to sell $4,000 worth of merchandise.

If she needs to earn $320, and she earns 8% commission, you’re looking for what 8% of original amount equals $320.

X = original amount
8% = .08
$320 = amount needed

X * .08 = $320.
X = $320/.08
X= $4,000

Kristen needs to sell $4,000 worth of merchandise at an 8% commission rate to earn $320.
