Manuel builds and sells wooden crates. He made this table to show how much his crates cost in dollars.

2 answers:

7 0

The difference between the costs is $20 and the difference in the crates is 2 so the slope is 20/2=10, the coefficient for x.
The equation then is y-k=10(x-h) where (x,y) is a pair of values from the table: (2,25), (4,45), (6,65), (8,85). Eliminate answers A and C because the coefficient is -10. Answer D has the (h,k) values the wrong way round, but B is correct in all respects so B is the answer.

Answer:

So you need to compute all the rates to see which is the best deal.

$1.79/12.5ft^2=$0.1432 per ft^2

$5.29/40ft^2=$0.13225 per ft^2

$8.49/50ft^2=$0.1698 per ft^2

$6/60ft^2=$0.10 per ft^2

So the last option is the cheapes per square foot and thus is the best deal. Ordered from least to greatest.

7x10 to the 3rd power, write a pattern to find the value of the expression

myrzilka [38]

Scientific notation is used to express very large or very small values.
Numbers in scientific notation are written in the form of
m × 10 to the power of n
For example:
500 is written as 5 x 10^2 where:
500 = 5 x 10 x 10

Now, let's consider 7 x 10^3:
Following the same procedure:
7 x 10^3 = 7 x 10 x 10 x 10 = 7000
The pattern can be written as:
7 x 10^3 = 7 x 10 x 10^2
= 70 x 10^2
= 70 x 10 x 10^1
= 700 x 10
= 7000

If n+h/5=f+9/9, then n/5=

Ann [662]

------------------------------------------------------------------
Question
------------------------------------------------------------------
$\boxed { \frac{n+h}{5} = \frac{f+9}{9}}$

------------------------------------------------------------------
Split the fraction on the left
------------------------------------------------------------------
$\boxed { \frac{n}{5} + \frac{h}{5} = \frac{f + 9}{9}}$

------------------------------------------------------------------
Take away h/5 from both sides
------------------------------------------------------------------
$\boxed { \frac{n}{5} = \frac{f+9}{9} - \frac{h}{5}}$

------------------------------------------------------------------
Change the denominator to be the same
------------------------------------------------------------------
$\boxed { \frac{n}{5} = \frac{5f+45}{45} - \frac{9h}{45}}$

------------------------------------------------------------------
Put it into single fraction
------------------------------------------------------------------
$\boxed { \frac{n}{5} = \frac{5f+45-9h}{45} }$

-------------------------------------------------------------------
Rearrange (This step may not be necessary)
------------------------------------------------------------------
$\boxed {\frac{n}{5} = \frac{5f-9h+ 45}{45} }$

$\bf \Longrightarrow \ Answer \ : \boxed {\boxed {\frac{n}{5} = \frac{5f-9h+ 45}{45} }}$

When are the absolute value and the opposite of a rational number equal

natulia [17]

|a| = -a if a < 0

The absolute value and the opposite of rational number is equal when a number is negative.

Examples:

|-7| = - (-7) = 7

|-0.5| = - (-0.5) = 0.5
