Answer:

\huge\boxed{x=14.2}

Step-by-step explanation:

Use a cosine:

cosine=\dfrac{adjacent}{hypotenuse}

We have:

adjacent=12\\hupotenuse=x\\measure\ of\ angle=32^o

Look at the picture or use the calculator.

\cos32^o=0.8480

Substitute:

0.848=\dfrac{12}{x}\\\\\dfrac{0.848}{1}=\dfrac{12}{x}

cross multiple

0.848x=12

divide both sides by 0.848

x=\dfrac{12}{0.848}\\\\x=14.2

One number is 9 more than twice another. If their difference is 22, what is the larger number?
mafiozo [28]
Let, the numbers are: x, y
So, Equations will be: x - y = 22
x = 2y + 9

Substitute the value of x in first equation, 
2y + 9 - y = 22
y = 22 - 9
y = 13

x - 13 = 22
x = 22 + 13 = 35

In short, Larger number would be 35

Hope this helps!

Ber [7]
Find the cost for one ticket for the science center.
36.75 ÷ 3 = 12.25
Multiply the product with 12 to get the cost of 12 tickets.
12.25 × 12 = 147
Find the cost of 1 zoo ticket.
51 ÷ 4 = 12.75
Find the cost of 12 tickets by multiplying the product and 12
12.75 × 12 = $153
12 Science Center Tickets cost $147
12 zoo tickets cost $153

The Zoo costs more than the Science Center.

To find out how much more the Zoo costed, subtract 147 from 153.
153 - 147 = 6
The zoo only costs $6 more for 12 students.
So, you're answers are Zoo and $6
