Help me solve this questions with steps please

Flauer [41]

Answer:

Step-by-step explanation:

Since the triangle is right use the tangent ratio to find x

tan22° = $\frac{opposite}{adjacent}$ = $\frac{203}{x}$

Multiply both sides by x

x × tan22° = 203 ( divide both sides by tan22° )

x = $\frac{203}{tan22}$ ≈ 502.5 m → B

I need help with this ASAP and can you explain so i can understand?!

Answer:

Adult tickets sold = 225

Student Tickets sold = 375

Step-by-step explanation:

Let:

Adult tickets sold = x

Student Tickets sold = y

Total tickets sold = 600

So, we can write: x+y = 600

Total money collected = 3037.50

Cost of 1 Adult ticket = $6.00

Cost of one Student ticket = $4.50

So, we can write: 6x+4.5y=3037.50

Now, we get a system of equations, that if solved we can find values of x and y

Let:

$x+y = 600--eq(1)\\6x+4.5y=3037.50--eq(2)$

We can solve using substitution method.

Finding value of x from eq(1) and putting it in eq(2)

$We\:have\\x+y=600\\x=600-y$

Put in eq(2)

$6x+4.5y=3037.50\\6(600-y)+4.5y=3037.50\\3600-6y+4.5y=3037.50\\-1.5y=3037.50-3600\\-1.5y=-562.5\\y=\frac{-562.5}{-1.5}\\y=375$

So, we get value of y = 375

Now put value of y in eq(1) to find value of x

$x+y=600\\Put\:y=375\\x+375=600\\x=600-375\\x=225$

So, we get value of x = 225

The Tickets sold will be:

Adult tickets sold = x = 225

Student Tickets sold = y = 375

How do you use the order of operations to evaluate expressions with exponents?

IgorLugansk [536]

Using BEDMAS, it would be brackets first, so anything Inside a set of brackets would be solved first, and would follow the same rule. Once the brackets have been solved, next would be the exponents. Since your brackets have been solved you can expand with the exponents. After exponents, would be anything that has to be divided or multiplied. These two operations are interchangeable based on what is more convenient or beneficial to do first. And lastly, addition and subtraction, which once again are interchangeable operations

If dy/dt=-2y and if y=1 when t=0, what is the value of t for which y=1/2

gladu [14]

$\bf \displaystyle \int -2t\cdot dt\implies -2\int t\cdot dt\implies -2\cdot \cfrac{t^2}{2}+C
\\\\\\
-t^2+C=f(x)\qquad 
\begin{cases}
f(x)=y=1\\
t=0
\end{cases}\implies -0^2+C=1\implies C=1
\\\\\\
-t^2+1=f(x)\\\\
-----------------------------\\\\
-t^2+1=f(x)\qquad f(x)=\cfrac{1}{2}\implies -t^2+1=\cfrac{1}{2}
\\\\\\
1-\cfrac{1}{2}=t^2\implies \pm \sqrt{\cfrac{1}{2}}=t\implies \cfrac{1}{\pm \sqrt{2}}=t
\\\\\\
\pm \cfrac{\sqrt{2}}{2}=t\impliedby \textit{with a rationalized denominator}$
