In scientific notation, how can you tell if it is less than or greater than 1? Explain

Mathematics

svlad2 [7]3 years ago

Answer: See below

Step-by-step explanation:

In scientific notation, you can tell that it is greater or less than 1 by looking at the exponent. The scientific notation looks like _.__×10⁻. Note: The little lines are blanks for you to fill in. The dot at the bottom is a decimal.

If the exponent on top of 10 is positive, you are moving the decimal to the right side, making the number greater.

If the exponent on top of 10 is negative, you are moving the decimal to the left side, making it smaller and smaller.

By those statements, you can tell if a number is greater or less than 1 by looking at the exponent.

Betty has 741 coins in her piggy bank, worth a total of 10,725 cents. The piggy bank only contains quarters and dimes. How many
quester [9]
Let quarters = q and
Dimes = d

We have 741 coins total so q + d = 741

Since quarters are 25 cents and Dimes are 10 cents then

25q + 10d = 10725 cents

Now we have 2 equations that we can solve using addition or substitution.

Using addition, first multiply the first equation by -10

-10 (q+d) = 741 (-10)
-10q - 10d = -7410

Now add the equations together

(-10q -10d = -7410)
+ (25q + 10d =10725)
________________
15q = 3315
q = 3315 / 15
q = 221
this is the number of quarters

Now plug this back into the original equation

q + d = 741
221 + d = 741
d = 741 - 221
d = 520

There are 520 dimes

Which points can be connected to draw a line of symmetry through this diamond?
Makovka662 [10]

The line is drawn at point A and Point C is a line of symmetry because lines of symmetry make exactly two halves with similar shapes and sizes.

<h3>What is a line of symmetry?</h3>

It is defined as the line which will make exactly two halves with similar shape and size in geometry. For a two-dimensional shape, there is a line of symmetry, and for three-dimensional shapes, there is a plane of symmetry. In other words, if we make a mirror image of the shape around the line of symmetry, we will get exactly the same half portion.

We have given a figure in the picture.

The figure is a quadrilateral(a kite)

As we know, lines of symmetry make exactly two halves with similar shapes and sizes.

IF we draw a line from Point A to Point C we will get two similar and figures in size and shape.

Thus, the line is drawn point A and Point C is a line of symmetry because lines of symmetry make exactly two halves with similar shapes and sizes.
