Write the number 1/10,000,000 as a power of 10 using a negative exponents

allochka39001 [22]

First, convert into a decimal:

1/10,000,000 = 0.00000001

Next, convert to "the number with a power of 10 using a negative exponent. Move the decimal point to the first <em>number that is not 0</em> (sorry, there is a term for it, but i can't remember it right now, but it is not important to solving the answer)

0.000001 = 1 * 10^-7

1 * 10^-7 is your answer

Figure I and Figure II are similar figures,

ELEN [110]

The ratio of corresponding sides is same for all the sides for similar polygon. the correct proportion is,

$\frac{ST}{EF}=\frac{WR}{CD}$

Thus the option H is the correct option.

To find the correct proportion we need to know about the properties of slimier polygon.

<h3>What are the properties of similar polygon?</h3>

Two polygons are said to be similar or congruent pentagon-

The corresponding angle of two pentagons are congruent.

The ratio of corresponding sides is same for all the sides.

The figure given in the problem of similar two polygons with six sides.

Rearrange the second figure as shown in figure.

As for the similar polygons, the ratio of corresponding sides is same for all the sides.

Thus the sides shown in the two rearranged figure must be same. Therefore,

$\frac{ST}{EF}=\frac{WR}{CD}$

Hence the correct proportion is,

$\frac{ST}{EF}=\frac{WR}{CD}$

Thus the option H is the correct option.

.. pls help me....!!!!! Determine whether the point (-2,4) satisfy y<3x+5,y=3x+5 or y >3x+5..

nasty-shy [4]

Answer:

$y > 3\cdot x + 5$

Step-by-step explanation:

Let $A(x,y) = (-2,4)$ and $y = 3\cdot x + 5$ . Now we evaluate the given function at $x = -2$ :

$y = 3\cdot x + 5$ (1)

$y = 3\cdot (-2)+5$

$y = -6 +5$

$y = -1$

Which means that $y$ is less than the y-component of A. Therefore, the right answer is $y > 3\cdot x + 5$ .

Write as an algebraic expression: <br><br> 1) a% of 80 <br><br> 2) 17% of b <br><br> 3) a% of b

Anna35 [415]

1) 4a/5
a% of 80 = a% (80) = (a/100)(80) = 80a/100 = 4a/5

2) 17b/100 or 0.17b
17% of b = (17/100)(b) = 17b/100 [ = 0.17b ]

3) ab/100
a% of b = (a/100)(b) = ab/100
