Mathematics
1 answer:
olga nikolaevna [1]3 years ago
6 0

Answer:

7.  7.8

Step-by-step explanation:

We can use Tan of this angle to find the missing side (in this case, the side adjacent to the angle measuring 57°)

 Tan A = (opposite side)/(adjacent side)

    Tan 57° = 12/x

solve for x

           x(Tan 57°) = 12

               x = 12/(Tan 57°)

                 x = 7.8   (rounded to the nearest tenth)

Tell whether the sequence is geometric 31, 213, 4459, 637, 91,....​
Lubov Fominskaja [6]

Answer:

No.

Step-by-step explanation:

If it is geometric  the quotient of the terms and the previous term will be a constant.

213 / 31 = 6.871

4459 / 213= 20.93

These are not equal so the sequence is not geometric.

What is 2 times 5 to the 3rd power divided by (9-4) raised to the power of 4
Maslowich
Heyo Kiddo. How are you doing today? 

Let's figure this out. 

So in number form, the equation will be looking a little like this: 

2(5) ^{3} / (9-4)^4

To solve. 

2(5) ^{3} / (9-4)^4 \ \textless \ Parenthesis first\ \textgreater \ 

2(5)^{3} / 5^4 \ \textless \ Exponents\ \textgreater \ 

2(125) / 625 (Multiply)

250 / 625  (Divide)

0.4  (Answer)

So I hope this answers your question and that you have a great day. :)

The sales tax on a $350 computer is $ 22.75. find the sales tax rate.
likoan [24]

Set up an equation to solve for the tax rate, x:

350(x) = 22.75\\x = \frac{22.75}{350}\\x = 0.065\\x = 6.5%


We can conclude that the tax rate on the computer was 6.5 percent.
