I have a hard time with fractions and I need help. <br><br> 6 2/3 × 5/6=
laila [671]

When you multiply fractions you want to make them a mixed number then multiply the two top numbers together and then the bottom two together. Basically 6 2/3 would become 20/3 x 5/6... then multiply 5 and 20 together and 3 and 6 together to get 100/18... simplify from there.

If the altitude of an isosceles right triangle has a length of x units, what is the length of one leg of the large right triangl
SVETLANKA909090 [29]

the picture in the attached figure

we know that

if ABC is an isosceles triangle

then

AB=BC

angle A=angle C=45 degrees

and

triangle ABD and triangle BDC also are isosceles triangles

AD=BD=x

DC=BD=x

the hypotenuse AC is equal to

AC=AD+DC\\ AC=x+x\\ AC=2x

To find the length AB applying the Pythagorean Theorem

AC^{2} =AB^{2} +BC^{2}

remember that AB=BC

AC^{2} =2AB^{2}

AC^{2} =2AB^{2}\\\\ AB=\frac{AC}{\sqrt{2}}\\\\ AB=\frac{2x}{\sqrt{2}}\\\\ AB=x\sqrt{2}

therefore

the answer is

the length of one leg of the large right triangle in terms of x is equal to x\sqrt{2}

A movie screen has an area of 162 square meters and a perimeter of 54 meters. What are the dimensions of the screen?
ololo11 [35]

Answer:

18 meters by 9 meters (or 9 meters by 18 meters)

Step-by-step explanation:

lets say the dimensions are x and y. we have x*y=162, and 2x+2y=54. from the second equation we have x+y=27 so y=27-x. plug this into the first equation to get x(27-x)=162 or -x^2 + 27x = 162. x^2 - 27x + 162 = 0. simplify to get (x-18)(x-9)=0. so x=18 or x=9. when x=18, y=9, when x=9, y=18 so the dimensions are 18 by 9 meters
