Answer:

3+3tt=total amount of snow

Step-by-step explanation:

y=mx+b is used to show increase

In this case, b is the original 3 inches of snow. m is the constant growth, and x is tt, or the amount of time it is being compared to. y is the total.

Lerok [7]

Answer:

x = 10

Step-by-step explanation:

3x - 5 = 2x + 5

Both triangles equal 25

Subtract 2x → You get left with x

x -5 = 5

Add five... which leaves you with↓

x = 10

Then substitute x for 10

(3 · 10) - 5

25

(2 · 10) + 5

25

You know this is true because they equal each other.

I hope this could help!!

Question in picture<br><br>A) 16/63<br><br>B)-16/63<br><br>C) 63/16<br><br>D) -63/16
Orlov [11]
ANSWER
\tan(x + y) =  -  \frac{63}{16}


EXPLANATION


We were given that,

\csc(x)  =  \frac{5}{3}

This implies that,

\sin(x)  =  \frac{3}{5}

We use the Pythagorean identity

\sin^{2} (x)  +  \cos^{2} (x)= 1
to get,


\cos(x)  =  \sqrt{1 - ( { \frac{3}{5} })^{2}}  =  \frac{4}{5}


We were also given that,


\cos(y)  =  \frac{5}{13}

This means that,


\sin(y)  =  \sqrt{1 -  {( \frac{5}{13}) }^{2} }  =  \frac{12}{13}

This is because,


0 <  \: x \:  <  \frac{\pi}{2}


0 <  \: y \:  <  \frac{\pi}{2}

This angles are in the first quadrant so we pick the positive values.

\tan(x + y)  =  \frac{ \sin(x + y) }{ \cos(x + y) }


\tan(x + y)  =  \frac{ \sin(x ) \cos(y)   +  \sin(y)  \cos(x) }{ \cos(x) \cos(y)  -  \sin(x)  \sin(y) }



\tan(x + y)  =  \frac{  \frac{3}{5}   \times  \frac{5}{13}  +   \frac{12}{13}   \times  \frac{4}{5}  }{  \frac{4}{5}  \times  \frac{5}{13}   -   \frac{3}{5}  \times  \frac{12}{13}  }



\tan(x + y) =  -  \frac{63}{16}

Matt plans to put concrete on a rectangular portion of his driveway. The portion is 8 feet long and 4 inches high. The price of
kakasveta [241]

Answer:

The width of the yard is approximately 6 feet.

Step-by-step explanation:

1 cubic yard = 27 cubic feet. Then we must find the number of cubic yards.

So we know for 1 cubic yard = $98

And for "x" cubic yard = $58.07

1/x =98/58.07

x = 0.5925

After we figure this out we need to convert this into cubic feet

1 cubic yard = 27 cubic feet

0.5925 cubic yard = x cubic feet

1/0.5925= 27/x

x = 15 .99 cubic feet

So,

width x height x length = 16 cubic feet

w x 8 x (1/3) = 16

w = 48/8 = 6 feet

So:

The answer is:

The width of the yard is approximately 6 feet.

Hope this helps, have a good day. c;
