M+(-9.5)=-7.8 how do you do this problem

Answers

Answer 1

Answer: m + (-9.5) = -7.8

First, simplify your brackets. / Your problem should look like: $m + -9.5 = -7.8$
Second, change addition to subtraction. / Your problem should look like: $m - 9.5 = -7.8$
Third, add 9.5 to both sides. / Your problem should look like: $m = -7.8 + 9.5$
Fourth, simplify. / Your problem should look like: $m = 1.7$

Answer: m = 1.7

An adventure game has a number cube with 12 equal-size faces: some labeled with 1, some labeled with 2, and some labeled with 3. The game manufacturer tests the cube by rolling it 12, then 120, and then 1200 times.What is the best estimate of the number of faces labeled with 2?

Answers

The best possible estimate will be the amount of twos rolled out of twelve hundred times, divided by 100 and rounded to the nearest integer.

Step-by-step explanation:

The shape of the new pizza must meet the conditions:

Be an irregular polygon (different sides and/or angles).
Have at least five sides.
Have the approximately the same area as a 14" diameter circle.
Fit in a 14⅛" × 14⅛" square.
Be divisible into 8-12 equal pieces.

For simplicity, I will choose a polygon with 5 sides (a pentagon), and I will use 2 right angles (a "house" shape).

Split the pentagon into a rectangle on bottom and triangle on top. If we cut the rectangle into 8 pieces like a regular pizza, and the triangle in half, we get 10 triangles.

Now we just need to figure out the dimensions. The area of a 14" circular pizza is:

A = πr²

A = π (7 in)²

A ≈ 154 in²

That means the area of each triangle slice needs to be 15.4 in². If we make the total width of the pentagon 14", then the width of each triangle is 7", and the height of each triangle is:

A = ½ bh

15.4 in² = ½ (7 in) h

h = 4.4 in

Which makes the total height of the pentagon 3h = 13.2 in.

So, our 13.2" × 14" pentagon has at least 5 sides, is irregular, has the same area as a 14" diameter circle, fits in a 14⅛" × 14⅛" square, and can be divided into 8-12 equal pieces.

Of course, there are many possible solutions. This is just one way.

Answer:

our 13.2" × 14" pentagon has at least 5 sides, is irregular, has the same area as a 14" diameter circle, fits in a 14⅛" × 14⅛" square, and can be divided into 8-12 equal pieces.
