Answer:

The third side is around 58.043

Step-by-step explanation:

Use the law of cosines: $c^2=a^2+b^2-2abcos(C)$

Plug in the two sides we know (into a and b) and the angle we know (into angle C).

Thus:

$c^2=32^2+35^2-2(32)(35)cos(120)$

Use a calculator:

$c^2=3369\\$

$c=58.043087...$

Taylor needs to repair her car but cannot spend more than $260 for the repairs. The part needed for the repair will cost $80 and

Oksanka [162]

Answer: 6 hours

Step-by-step explanation:

Taylor cannot spend over $260.

Subtract the cost of the part needed for the repair:

= 260 - 80

= $180

$180 is left for fixing the car after buying the part.

As the labor costs $30 and now she cannot exceed $180 for labor, the total number of hours the mechanic can work is:

= 180 / 30

= 6 hours

I NEED HELP WITH THIS. PLEASE HELP. I'M GETTING GRADED ON IT TODAY.

choli [55]

Answer:

Point P = (-9,11)

Step-by-step explanation:

Point M: (1,3) X and Y have the 2 on the bottom right of them

Midpoint N: (-5,7)

Point P: (X*2, Y*2)

( 1 + X*2 3 + Y*2 )

( _______ ________ ) = (-5 , 7)

( 2 , 2 )

( 1 + X*2 )

( _____ ) = -5

( 2 )

Then multiply the left equation above by 2, and that cancels out the 2 being

divided on the bottom. Also, multiply the -5 by 2 and you get -10

1 + X*2 = -10

+1 +1

__________

X*2 = -9

X = -9

( 3 + Y*2 )

( ______ ) = 7

( 2 )

Then multiply the left equation above by 2, and that cancels out the 2 being divided on the bottom. Also, multiply the 7 by 2 and you get 14

3 + Y*2 = 14

-3 -3

_________

Y*2 = 11

Y = 11

Hope this helps, good luck! :)

If the average speed of a garden snail is 0.025 miles per hour and one inch is approximately 2.54 centimeters, how many minutes

BaLLatris [955]

Snail takes 1.5 minutes to travel around one meter

<u>Solution:</u>

Given, the average speed of a garden snail is 0.025 miles per hour

And one inch is approximately 2.54 centimeters,

We have to find how many minutes would it take a garden snail to travel one meter?

Now, let us convert the speed in miles per hour to meters per minute

Then, speed = 0.025 miles per hour

= 0.025 x 1 mile / 1 hour

= 0.025 x 1609.34 meters / 60 minutes

= 0.025 x 1609.34 / 60 meters per minute

$\begin{array}{l}{=\frac{0.025 \times 1609.34}{60} \text { meters per minute }} \\\\ {=\frac{40.2335}{60} \text { meters per minute }}\end{array}$

= 0.670 meters per minute.

Now, 0.670 meters ⇒ 1 minute

Then, 1 meter ⇒ n minutes

So, by criss cross method

n x 0.67 = 1 x 1

n = 1.4912

Hence, snail takes 1.5 minutes approximately to travel 1 meter.
