Answer:

AC ≈ 17.3 cm

Step-by-step explanation:

Using the tangent ratio in the right triangle

tan68° = $\frac{opposite}{adjacent}$ = $\frac{AC}{AB}$ = $\frac{AC}{7}$ ( multiply both sides by 7 )

7 × tan68° = AC , then

AC ≈ 17.3 cm ( to 1 dec. place )

We will use tangent here as we are finding the opposite with the adjacent given.

So we can simply just put this into a calculator:

tan(68°) × 7 cm = AC

tan(68°) × 7 cm = 17.3 cm

What is the answer to x=3x-20 and y=-6+30

NISA [10]

Answer:y=24 and x=10

Step-by-step explanation:

To find the value of x and y in x=3x-20 and y=-6+30

We gets

y=24

To get x

x=3x-20

Collect like terms

x-3x=-20

Divide through by -2

-2x=-20

x=10

Mr. frankel bought 7 tickets to a puppet show and spent $24. he bought a combination of child tickets for $2 each and adult tick

nydimaria [60]

Let x be the number of child tickets he bought
Let y be the number of adult tickers he bought

① x+y=7 (child tickets+adult ticket=7 tickets in total)
② 2x+4y=24 (price of child tickets+price of adult tickets=$24 in total)

We may simply the second equation since all of the coefficients are divisible by 2.

① x+y=7
② x+2y=12

We can now use elimination by multiplying the second equation by -1.

② -(x+2y=12)
② -x-2y=-12

① x+y=7
② -x-2y=-12

Now putting the equations together,
-y=-5
y=5
x=2

Therefore he bought 2 child tickets and 5 adult tickets

HELP ME PLEASE!!! What is the value of y for the parallelogram shown A. 66 B. 60 C. 22 D. 38

Nesterboy [21]

Answer:

Option C is the correct option.

Solution,

 $3y = 66$ 

(opposite angles of parallelogram are equal )

 $or \: 3 \times y = 66 \\ or \: y = \frac{66}{3} \\ y = 22$ 

hope this helps...

Good luck on your assignment..

Pls help to get the answer

When they say quotient, they want a fraction, so the answer for that would be
$\frac{6}{10}$
and the decimal form of that would be 0.6. You can get that from dividing 6 by 10 and solving with long division.
