Answer:
The volume of the cube is 1/2 x 1/2 x 1/2 = 1/8
length x width x height = volume
1x2x2.5=5
2 1/2 = 2.5 because 1/2=0.5
to divide fractions multiply the reciprocal. The reciprocal is the fraction flipped over
5 / 1/8 = 5 x 8/1
5x8/1=40
40 cubes

Step-by-step explanation:
we know that
The scale drawing is
using proportion find out the width of the great room on her plan
Answer:
B
Step-by-step explanation:
The Distributive property says that a(b+c) = ab+ac
In my example you distribute the value on the outside to the things on the inside
In your problem, you have a six on the outside that needs to be distributed to an a and b
1) 6 multiplied by a equals 6a giving you the first part of your answer!
2) 6 multiplied by b equals 6b giving you the second part of your answer!
Dont forget that there is a + sign in between a and b, dont drop it!
Put the two values together to get 6a+6b
Let me know if you have any further questions :)
Answer:
x=2*sqrt(5)
Step-by-step explanation:
Since the triangle is isosceles, the other side of the triangle is sqrt(10) too. By using Pythagoras theorem, we have 10+10=x^2, x=2*sqrt(5).
-- The smallest perimeter you can make with a certain area
is a circle.
-- The NEXT smallest perimeter with the same area is a square.
With 1-ft by 1-ft square bricks, the shortest perimeter she could
make would be by using her bricks to make it as square as possible.
Without cutting bricks into pieces, the best she could do would be
(13 bricks) x (3 bricks) .
= (13-ft) x (3-ft)
Perimeter = (2 x length) + (2 x width)
= (2 x 13-ft) + (2 x 3-ft)
= (26-ft) + (6-ft) = 32 feet <== shortest perimeter.
-- Then, the more UNSQUARE you make it, the more perimeter
it takes to enclose the same area. That means Mary has to make
a rectangle as long and skinny as she can.
The longest perimeter she can make (without cutting bricks into
pieces) is (39 bricks) x (1 brick) .
= (39-ft) x (1-ft) .
Perimeter = (2 x length) + (2 x width)
= (2 x 39-ft) + (2 x 1-ft)
= (78-ft) + (2-ft) = 80 feet .
What she'll have then is a brick path, 39 feet long and 1 foot wide,
and when you walk on it, you'll need to try hard to avoid falling off
because it's only 1 foot wide.
