Mathematics
2 answers:
VARVARA [1.3K]2 years ago
6 0

Step-by-step explanation:

rewrite the equation as x/7 = tan (30).

x/7= tan (30)

multiply both sides of the equation by 7 .

7•x/7=7• tan (30)

simplify both sides of equation x=7π3/3

the result can be shown in multiple forms exact forms x=7π3/3

decimal form x=404145188...

TAN (30) =X/7

tan(30) = (\frac{x}{7} )\\x = 7*tan(30)

After this step, find the button on your calculator that says 'tan' and type n 30 degrees, then press enter or the equal sign or whatever button you press to calculate.

You should get that tan(30) = 0.5774

Now plug that back into the equation

     x = 7 * 0.5774 = 4.0415 (approximated)

Hope that helps!

VikaD [51]
For this case, the first thing to do is to calculate the time you were watching the game.
 We have then:
 2:00 - 1:45 = 15 minutes
 Then, the amount of degrees is given by:
 (15/60) * (360) = 90 degrees
 Answer:

Step-by-step explanation:

xy=k

Value of k ; when ; x = - 3 and y = - 2

Put x = - 3 and y = - 2 into the equation :

(-3)(-2) = k

-3 * - 2 = k

6 = k

The constant of variation k = 6

13. For what value of b would the following system of equations have an infinite number of solutions?
tiny-mole [99]

Answer:

b=2

Step-by-step explanation:

we have

9x+12y=21 -----> equation A

6x+8y=7b ----> equation B

we know that

If the system of equations have an infinite number of solutions then the equation A must be equal to the equation B

Multiply equation B by 1.5 both sides

1.5*[6x+8y[=7b*1.5

9x+12y=10.5b ----> equation C

Compare equation A and equation C

9x+12y=21 -----> equation A

9x+12y=10.5b ----> equation C

For the equations to be equal it must be fulfilled that

21=10.5b

solve for b

b=21/10.5

b=2
