to cut the block of clay into two pieces. He places a wire across the diagonal of one face of the cube. Then he pulls the wire straight back to create two congruent chunks of clay.
Daniel wants to keep one chunk of the clay for later use. To keep that chunk from drying out, he wants to place a piece of plastic sheeting on the surface he exposed when he cut the cube. describe this newly exposed two-dimensional cross-section, and find its area. round your answer to the nearest whole square inch

14 the maximum number of spheres that Daniel can make from the chunk of clay.

.

Step-by-step explanation:

10^3=1000 in^3

1000/2=500 vol of one congruent chunk.

4/3 * pi * r^3 = vol of a sphere

500/(4/3 * pi * 2^3)

=14.92...

House sold for $132000. Seller made 10% over original purchase price. What is the original purchase price of house
Sergio [31]
<span>V (sale value) = $ 132000
P (profit) = 10% on the sale, ie 10/100 * 132000 = 1320000/100 = $ 13200
C (cost) = ?

As:

V = C + P
132000 = C + 13200
C = 132000-13200
C = 118800

Answer:

He paid $ 118800 for the house (</span><span>Purchase price of house)</span>

if you subtract 17 from my number and multiply the difference by -6 the results is -138 what is Sarah's number
likoan [24]

Answer:

40

Step-by-step explanation:

let the unknown be y (x is used as times(multiplication) )

(y-17)x-6=-138

add /-6 to both sides

y-17x-6/-6=-138/-6

y-17=23

make y independent/add 17 to both sides

y-17+17=23+17

y=40

or in an easier way

-138/-6 =23

23+17=40

Point M is the midpoint of AB . Through point M a line segment XY is drawn, so that both XA and YB are perpendicular to AB . Pro
GaryK [48]

Answer:

See the proof below

Step-by-step explanation:

Let the line AB be a straight line on the parallelogram.

A dissection of the line (using the perpendicular line X) gives:

AY ≅ BX

Another way will be using the angles.

The angles are equal - vertically opposite angles

Hence the line  AY ≅ BX (Proved)
