If the height was 10, then the volume of the cube would be 1000 because you find volume you must multiply the length*width*height and the value of those three is 10.
Now since volume is 1000 and the volume of a 2in cube is 8 (again, lwh=V) you can divide 1000 by 8 and you would get 125. So that means 125 2in cubes can fit inside the bigger cube.
If the volume of this cube were 750in^3 and you had to find the height, you would use the Volume formula again:
l*w*h=V
10*10*h=750
20h=750
((divide both sides of the equation by 20 to find the value of h))
h=37.5
If the surface area of the cube were 680in^2 then you would use the surface area formula to find the value of h:
(2(lw))+(2(lh))+(2(wh))=A
(2(10*10))+(2(10h))+(2(10h))=680
200+20h+20h=680
subtract 200 from both sides of the equation:
40h=480
divide both sides by 40 to get the value of h:
h=12
Answer:
The angles across from the legs are called base angles
Step-by-step explanation:
we know that
The isosceles triangle is a triangle with two equal angles and two equal sides
The two equal sides are called legs and the third side is called base
The two equal angles are called base angles and the third angle is called vertex angle
Do you have a protractor?
Sin (x + y) = sin x cos y + cos x sin y
<span>sin 255 </span>
<span>= sin (210 + 45) </span>
<span>= sin 210 cos 45 + cos 210 sin 45 </span>
<span>= (-1/2)(√(2)/2) + (-√(3)/2)(√(2)/2) </span>
<span>= -√(2)/4 + (-√(6)/4) </span>
<span>= -√(2)/4 - √(6)/4 </span>
<span>= (-√(2) - √(6)) / 4</span>
Answer:
The price before sales tax was added was $9.72.
Step-by-step explanation:
- 48.60 x 0.8 = 38.88 (Sales tax price)
- 48.60 - 38.88 = 9.72 (Price before sales tax)
