Answer:

subtracting 7 from 12

Step-by-step explanation:

That would be most efficient. Subtracting seven from twelve will quickly give you your value of x without moving the x itself. And there's no negatives

Answer:

Add -7 to both sides because that will result in an equivalent

equation with x alone on one side

Answer:

  a) 2

  b) left: 3; lower right: 5

  c) upper right: 53°; bottom: 82°

Step-by-step explanation:

<h3>3.</h3>

a) The top side of polygon B is 5 units; the corresponding top side of polygon A is 2.5 units, so the dimensions of polygon A are multiplied by the scale factor 5/2.5 = 2 to give the dimensions of polygon B.

  the scale factor is 2

__

b) Sides of polygon B are 2 times the length of the corresponding side of polygon A.

  left side: 2×1.5 = 3

  lower right side: 2×2.5 = 5

__

c) Corresponding angles of similar figures are congruent.

  upper right angle: 53°

  bottom angle: 82°

___

4.

The arithmetic of problem 4 is correct as shown.

Write your answer in scientific notation (2.5•10^8)•(2•10^3)
ICE Princess25 [194]

Answer:

5\times10^{11}

Step-by-step explanation:

In order to get the answer to this question you will have to put the scientific notations into their number form then multiply, then change back into scientific notation form.

(2.5\times10^8)\times(2\times10^3)

Turn the notations into their number form:

2.5\times10^8

The exponent is positive so move the decimal point to the right:

2.5\times10^8=250000000

Do the same with the second notation:

2\times10^3

Since the exponent is positive move the decimal point to the right:

2\times10^3=2000

Now multiply:

250000000 \times 2000 = 500000000000

Now turn the number into scientific notation:

500000000000 = 5.0\times10^{11}

=5\times10^{11}

Hope this helps.

A carton designer is considering a cost as she is comparing different shaped cartons. Which of these nets would create a cardboa
svlad2 [7]

Answer:

The first option i.e. (8 in × 10 in × 10 in) will be our choice.

Step-by-step explanation:

Each of the cartons shown here has the same volume i.e. 800 cubic inches.

Therefore, the carton having the least surface area will require the least amount of cardboard for each cubic inch of volume.

2(LW + WH + LH) is the surface area of a cuboid with dimensions L × W × H.  

Now, in the first option of cardboard with dimension 8 in × 10 in × 10 in, will have surface are = 2(8 × 10 + 10 × 10 + 8 × 10) = 520 sq, inches.

Now, in the second option of cardboard with dimension 5 in × 8 in × 20 in, will have surface are = 2(5 × 8 + 8 × 20 + 5 × 20) = 600 sq, inches.

Again, in the third option of cardboard with dimension 4 in × 10 in × 20 in, will have surface are = 2(4 × 10 + 10 × 20 + 4 × 20) = 640 sq, inches.

Finally, in the fourth option of cardboard with dimension 2 in × 10 in × 40 in, will have surface are = 2(2× 10 + 10 × 40 + 2 × 40) = 1000 sq, inches.

Hence, the first option will be our choice. (Answer)
