Which exponent is missing from this equation 5.6=56,000

Mathematics
1 answer:
Neko [114]3 years ago
6 0

Answer:

The missing exponent is 4

Step-by-step explanation:

Let

5.6 \times  {10}^{n}  = 56000

Then we rewrite the LHS in scientific notation to get;

5.6 \times  {10}^{n}  = 5.6 \times  {10}^{4}

This implies that,

{10}^{n}  =  {10}^{4}

By comparison, we find n=4.

Therefore the missing exponent is 4

Write a complete sentence that states the type of transformation that was performed and explains the transformation in detail. Q
Cerrena [4.2K]
The type of transformation that has happened is a translation. Translation is when the image's size nor shape changes after transformation. every point in the image moves the same distance in the same direction.
the equation for the translation mentioned is;
T4, -5(x,y)
this means that every point in the image has moved down by 5 units and moved to the right by 4 units.
Point A to Point E
Point A - (-4,-1)
after translation (x+4, y-5) = (-4+4,-1-5)
                                          = (0,-6) these are the coordinates of point E.
the other three points too have moved the same distance and direction as point  A did.

The lee's spend $ 31 on movie tickets for 2 adults and 3 children. The Smith's spent $ 26 on movie tickets for 2 adults and 2 ch
Trava [24]

Answer:

Cost of adult ticket is $8 and Cost of children ticket is $5.

Step-by-step explanation:

Given:

Let the cost of each Adult ticket be 'x'.

Let the cost of each child ticket be 'y'.

Now Given:

The lee's spend $ 31 on movie tickets for 2 adults and 3 children.

Number of adult tickets = 2

Number of children ticket = 3

Total money spent = $31

So we can say that;

Total money spent is equal to sum Number of adult tickets multiplied by cost of each Adult ticket and sum Number of children tickets multiplied by cost of each child ticket.

framing in equation form we get;

2x+3y=31 \ \ \ \ equation \ 1

Also Given:

The Smith's spent $ 26 on movie tickets for 2 adults and 2 children

Number of adult tickets = 2

Number of children ticket = 2

Total money spent = $26

So we can say that;

Total money spent is equal to sum Number of adult tickets multiplied by cost of each Adult ticket and sum Number of children tickets multiplied by cost of each child ticket.

framing in equation form we get;

2x+2y=26 \ \ \ \ equation \ 2

Now Subtracting equation 2 from equation 1 we get;

2x+3y-(2x+2y)=31-26\\\\2x+3y-2x-2y=5\\\\y=\$5

Now substituting the value of y in equation 1 we get;

2x+3y=31\\\\2x+3\times5 =31\\\\2x+15=31\\\\2x=31-15\\\\2x=16x\\\\\frac{2x}{2}\frac{16}{2}\\\\x=\$8

Hence Cost of adult ticket is $8 and Cost of children ticket is $5.

What is the length of segment AB?
olasank [31]

Answer:

The answer is 6.403

Step-by-step explanation:

Using the pythagorean theorem, a^2+b^2=c^2, we can plug 4 units into a, and 5 units into b. Plugging these into the formula results in 4^2 + 5^2 = c^2. Simplifying, we get 16 + 25 = c^2. Simplifying even more, we get 41 = c^2. Using a calculator to get the square root of both sides results in c = 6.40312424.

Make for me number 21 thx
xz_007 [3.2K]

Method One

You could divide by 5 right away.

20/5 = - 3 + x

4 = - 3 + x Add 3 to both sides.

4 + 3 = x

x = 7

Method Two.

You could remove the brackets. This is slightly longer, but some questions can only be solved that way.

20 = 5(-3) + 5x

20 = -15 + 5x Add 15 to both sides

20 + 15 = 5x

35 = 5x Divide by 5

35/5 = x

7 = x
