Initial repair cost = $1200

Gratuity = 15% of the initial repair cost

= 15% of 1200

$=\frac{15}{100} (1200)$

= 15 × 12

= 180

Hence, the gratuity for the service is $180.

Answer:

D) 9:20 am

Step-by-step explanation:

Train A's route = 20 mins

Train B's route = 80 mins

80 ÷ 20 = 4

Therefore, Train B's route is 4 times the length of Train A's route.

Therefore, the time Train A and B will leave the station at the same time will be the first time Train B leaves after 8am.

1 hour = 60 minutes

8am + 80 minutes = 8am + 1 hr + 20 minutes = 9:20 am

\tan \left(18\right)=\frac{x}{20}

noname [10]

Answer:

x ≈ 6.5

Step-by-step explanation:

We have the epresion $tan(18)=\frac{x}{20}$ and we want to find the value of $x$ .

Let's do it step-by-step

Step 1. Multiply both sides of the equation by 20

$tan(18)=\frac{x}{20}$

$20tan(18)=(\frac{x}{20} )(20)$

$20tan(18)=x$

Step 2. use the reflexive property of equality: if $a=b$ then $b=a$

$20tan(18)=x$

$x=20tan(18)$

Step 3. Using a calculator we get that $tan(18)=0.325$ . Replacing that value we get

$x=20(0.325)$

x ≈ 6.5

We can conclude that the value of x is approximately 6.5

What is the answer to this question

umka21 [38]

First you bring the 9 over with the seven
$-2= \sqrt[3]{x+9}$
Now cube both sides
$-8=x+9$
Finally subtract 9 over and get
$x=-17$

Check
$7=9+ \sqrt[3]{-17+9}$
$7=9+ \sqrt[3]{-8}$
$7=9+(-2)$
7=7
