The soccer team collected $800 at a car wash fundraiser. They charged $5.00 for small vehicles and $10.00 for larger

8 0

Answer:

60 is your answer.

Step-by-step explanation:

So what you do is add the 50 into the equation.

Since y represents the larger cars, you will put 50 in the y.

<u>5x + 10(50) = 800</u>

<u>5x + 500 = 800</u>

<u>5x = 300</u>

<u>x = 60</u>

So there were 60 small vehicles that where washed in the car wash.

What is the measure of X?

vlabodo [156]

Answer:

The answer is B.

Step-by-step explanation:

Given that the total angles in a triangle is 180° so in order to find the value of x, you have to substract 60° and 80° from 180° :

$60 + 80 + x = 180$

$140 + x = 180$

$x = 180 - 140$

$x = 40$

I need help with this question

Answer:

$\frac{\sqrt{3} - 1}{2\sqrt{2}}$

$\frac{-(\sqrt{3} + 1)}{2\sqrt{2}}$

$- \frac{\sqrt{3} - 1}{\sqrt{3} + 1}$

Step-by-step explanation:

Given $\frac{11 \pi}{12} = \frac{3 \pi}{4} + \frac{\pi}{6}$

(A) $sin(\frac{11\pi}{12}) = sin (\frac{3 \pi}{4} + \frac{\pi}{6})$

We know that Sin(A + B) = SinA cosB + cosAsinB

Substituting in the above formula we get:

$sin (\frac{3\pi}{4} + \frac{\pi}{6}) = \frac{1}{\sqrt{2}} . \frac{\sqrt{3}}{2} + \frac{-1}{\sqrt{2}}. \frac{1}{2}$

$$ \implies \frac{1}{\sqrt{2}} (\frac{\sqrt{3} - 1}{2}) = \frac{\sqrt{3} - 1}{2\sqrt{2}}$

(B) Cos(A + B) = CosAcosB - SinASinB

$cos(\frac{11\pi}{12}) = cos(\frac{3\pi}{4} + \frac{\pi}{6}})$

$\implies \frac{-1}{\sqrt{2}}. \frac{\sqrt{3}}{2} - \frac{1}{\sqrt{2}} . \frac{1}{2}$

$\implies cos(\frac{11\pi}{12}) = cos(\frac{3\pi}{4} + \frac{\pi}{6})$

$$ = \frac{-(\sqrt{3} + 1)}{2\sqrt{2}}$

(C) Tan(A + B) = $\frac{Sin(A +B)}{Cos(A + B)}$

From the above obtained values this can be calculated and the value is $- \frac{\sqrt{3} - 1}{\sqrt{3} + 1}$ .

This equation shows how the total cost of visiting the science museum as a member is related to the number of visits. c = 9.8v +

LiRa [457]

Well it's giving you what the cost is (42.3), so plug that in for $c$ :

$42.3 = 9.8v + 22.7$

And now you need to solve for the number of visits ( $v$ )!

$19.6 = 9.8v$

$v=2$

So you can visit the museum a maximum of 2 times!
