Find the length of the height of the right trapezoid shown below, if it has the greatest possible area and its perimeter is equa
Artyom0805 [142]

Answer:

The height of the right trapezoid is   \frac{6}{5+\sqrt{3}}\ units

Step-by-step explanation:

Let

x ----> the height of the right trapezoid in units

we know that

The perimeter of the figure is equal to

P=AB+BC+CD+DH+HA

we have

P=6\ units

AB=BC=CH=HA=x ---> because is a square

substitute

6=x+x+CD+DH+x

6=3x+CD+DH -----> equation A

<em>In the right triangle CDH</em>

sin(30\°)=\frac{CH}{CD}

sin(30\°)=\frac{1}{2}

so

Remember  that CH=x

\frac{1}{2}=\frac{x}{CD}

CD=2x

tan(30\°)=\frac{CH}{DH}

tan(30\°)=\frac{\sqrt{3}}{3}

so

\frac{\sqrt{3}}{3}=\frac{x}{DH}

DH=x\sqrt{3}

substitute the values in the equation A

6=3x+CD+DH -----> equation A

CD=2x

DH=x\sqrt{3}

6=3x+2x+x\sqrt{3}

6=5x+x\sqrt{3}

6=x[5+\sqrt{3}]

x=\frac{6}{5+\sqrt{3}}\ units

Past Piper's house at the end of the road were empty fields.
Romashka [77]

Answer:

18 Times

Step-by-step explanation:

Multiply the least amount by the six weeks. You multiply the least amount because the frog came every 3 days and the raccoon came every 7 days. Piper would see the frog and the raccoon at the same times on the least of the frog. The raccoon came all week while the frog came on limited times.

Hope this helps,

Carter E.

Can 100 rational numbers be inserted between 1 and 101
alexandr1967 [171]
Yes, they can. Rational numbers are also decimals (for example) so we can put an infinite amount of numbers between any 2 values, for example:

1,1
1,11
1,111
1,1111
2
5,328
5,3281
5,3282
