Barb is making a banner that is shaped like a trapezoid the height of the banner is 24 inches the top of the banner is it 14 inc

velikii [3]

Answer:

The length of the bottom side of the banner is 17 in.

Step-by-step explanation:

Given,

Area of the Banner = $372\ in^2$

Height of the Banner = 24 in

Top side of the Banner = 14 in

We have to find the length of the bottom side of the banner.

Solution,

Let the length of the bottom side of the banner be 'x'.

Since the banner is in the shape of trapezoid.

So according to the formula of area of trapezoid, which is;

Area of trapezoid = $\frac{1}{2}\times \textrm{sum of parallel sides}\times \textrm{distance between them}$

Here top and bottom sides are parallel and distance between them is equal to the height of the banner.

Now substituting the values, we get;

$\frac{1}{2}\times24\times(x+14)=372\\\\12(x+14)=372\\\\x+14=\frac{372}{12}\\\\x+14=31\\\\x=31-14=17\ in$

Hence The length of the bottom side of the banner is 17 in.

I need about 2 of these but pls explain so I can learn and try on my own pls

GuDViN [60]

These problems are based on the Pythagorean Theorem. The Pythagorean Theorem is a^2 + b^2 = c^2. If the two sides are equal, the triangle is a right triangle. If c^2 is less, the triangle is acute. If c^2 is more, the triangle is obtuse.

Obtuse: c^2 > a^2 + b^2

Acute: c^2 < a^2 + b^2

Right: c^2 = a^2 + b^2

#7 --- Obtuse

21^2 ___ 8^2 + 15^2

441 ___ 64 + 225

441 > 289

#8 --- Right

20^2 ___ 12^2 + 16^2

400 ___ 144 + 256

400 = 400

#9 --- Acute

6^2 ___ 4^2 + 5^2

36 ___ 16 + 25

36 < 41

Hope this helps!

Find the inverse relationship of the function y=2x+5

daser333 [38]

Answer:

y=x-5/2

Step-by-step explanation:

Swap y and x

x=2y+5

since a function has to be in the form y=mx+c

take 5 to the other side in order to remain with 2y then divide both sides by 2

x-5/2=y

y=x-5/2
