Answer:

Width = 20 inches

Step-by-step explanation:

Perimeter = 86 inches

Width = W

Length = 3 + W

Use the formula 2L + 2W = P to solve

Substitute new value for length (3 + w) into the formula

2(3 + W) + 2W = P

Change perimeter into the equation to 86 inches (Given)

2(3 + W) + 2W = 86

Multiply

6 + 2W + 2W = 86

Add the W's

6 + 4W = 86

Subtract 6 from both sides of the equation

4W = 80

Divide both sides of the equation by 4

W = 20 inches

Hope this helps :)

Please! Need help! Please answer 6 through 10! Brainliest! As a reward!
True [87]

Answer:

6=72 cm; 7=15 cm; 8=30 in; 9)56.5 degrees; 10)40 in

Step-by-step explanation:

6) The height of the triangle is 12 cm. The base is around 10 cm. Triangles are 1/2(b)h, so:

1/2(10)=5

5*12=60 cm

72 is closest to this.

7) Volume is l*w*h, so:

2.5*1.5=3.75

3.75*4=15 cm

8) Again, the height is 5 and the base is 12. 1/2(b)h means:

1/2(12)=6

6*5=30 in

9) All triangles have 180 degrees. So first, add the degrees you know:

33.5+90=123.5

Now, subtract that from 180:

180-123.5=56.5

10) Trapezoids can be found by multiplying the height by the smaller base, so:

6*8=40 in

Hope this helped!

Check the picture below.

thus then

\bf \begin{cases}
y=100-a\\
y=a\sqrt{3}
\end{cases}\implies 100-a=a\sqrt{3}\implies 100=a+a\sqrt{3}
\\\\\\
100=a(1+\sqrt{3})\implies \boxed{\cfrac{100}{1+\sqrt{3}}=a}
\\\\\\
\textit{what is the altitude \underline{y} then?}\qquad y=100-a
\\\\\\
y=100-\cfrac{100}{1+\sqrt{3}}\implies y\approx 63.39745962156~yards
