<span>100% of $X plus 100% of $Y equals $1000
4% of $X plus 6% of $Y equals $58
To solve that clear the second equation of decimals by
multiplying through by 100:
Solve that by either substitution or by elimination:
X = $100 at 4% and $900 at 6%</span>
Answer:
i am pretty sure it's a.
Step-by-step explanation:
i hope this helps :)
The correct answer is: [C]: " p = 6.25 h " .
______________________________________________________
Explanation:
______________________________________________________
It is clear that "pay" is a function of "hours worked" ;
So, we can eliminate: "Choice [B]: " h = <span>6.25p" .
______________________________________________________
Try, Choice [A]: " </span>p = h + 12.5 " ; and 14.50 ≠ 12.50 ; (12.50 is the amount shown in the table. So, we can already eliminate "Choice [A]".
<span>_____________________________________________
Now that we have eliminated choices [A] and [B];
we are left with choices: [C] and [D]:
_____________________________________________
Consider choice [C]: " </span><span>p = 6.25h " ;
</span> when "h = 2" ; does: "p = 12.5" (as shown on table)?? ;
i.e. " 12.5 =? 6.25 * (2) ?? Yes! This choice is a POSSIBILITY.
_____________________________________________
Consider choice [D]: " p = 12.5h" .
When "h = 2, does "p = 12.5" (as shown on table)? No!
→ We can see from this very answer choice
(the equation itself) that when "h = 2" ;
the value of "p" is DOUBLE [that of "12.5"].
________________________________________________
The correct answer is: Answer choice: [C]: " <span>p = 6.25 h " .

Answer:
8.28 units
Step-by-step explanation:
The formula for the circumference of a circle is 
where
is the circumference of the circle
is the diameter of the circle
We know form our problem that the circumference of our circle is 26.28 units, so 
. Let's replace that value in our formula and find :
Divide both sides of the equation by 
The diameter of the circle that has a circumference of 28.26 units is 8.28 units.
