Answer:

\large\boxed{c\approx3.31}

Step-by-step explanation:

Use cosine:

cosine=\dfrac{adjacent}{hypotenuse}

\cos\theta=\dfrac{b}{c}

We have:

\theta=25^o\to\cos25^o\approx0.9063\\\\b=3

Substitute:

\dfrac{3}{c}=0.9063

\dfrac{3}{c}=\dfrac{9063}{10000}          <em>cross multiply</em>

9063c=30000          <em>divide both sides by 9063</em>

c\approx3.31

"A ramp rises 1.5 feet for every 18 feet of horizontal distance it covers."
pishuonlain [190]
A ramp rises 1.5 feet <em>for </em>every 18 feet of horizontal distance. Basically the <em>for</em> is what gives it away. You could also just go with the fact that the x variable normally goes left to right (horizontal) and y goes up and down (Rises and falls) which gives you the same thing. The 1.5 feet is y and 18 feet is x

WILL.MARK BRAINLEST. ( The length of a rectangular garden is 5m longer than its breadth .If its perimeter is 150 m,find the area
inessss [21]

Answer:

1400m^2

Step-by-step explanation:

Solution,

Let the breadth of the rectangle be x m, then the length of the rectangle will be x+5 m,

Now,

Perimeter of the rectangle=2(l+b)

150=2(x+5+x)

150=2(2x+5)

150=4x+10

150-10=4x

140=4x

140/4=x

35=x

So, the breadth of the rectangle=35 m

and length=(35+5)m=40m

Again,

Area of the rectangle=l×b

=40m×35m

=1400 m^2

I hope it helped U

Fill in the other coordinate 2x-5y=11 (2,_)
Vlad [161]
The 2 is in the x place.
Let's substitute 2 for x in our equation.

2(2)-5y=11

Now, we can solve for y. (the other coordinate)

4-5y=11

Subtract 4 from each side.

-5y=7

Divide by -5.

y = -7/5 or -1 2/5 or -1.4
