25% as a decimal is 0.25, and since we subtract 25% we use (1 - 0.25)=0.75.
The price of the items after discount is $248.50*0.75 = $186.38
The sales tax (5% = 0.05) is added on, so we multiply by (1 + 0.05) = 1.05
$186.375*1.05 = $195.699 = $195.70
Answer:
The equation is: <em>y</em> = 15·<em>x</em>
Step-by-step explanation:
It is provided that at the Speedy Bike Works, 15 bicycles are produced each hour.
Consider the table below.
Number of Hours: 1 3 6 10
Number of Bicycles Produced: 15 45 90 150
Compute the ratio of number of bicycles produced and number of hours for every data above as follows:

The ratio of the number of bicycles produced and number of hours is same for every data value.
Thus, the relationship between the number of bicycles produced and number of hours is proportional.
The equation for the relationship is:
<em>y</em> = 15·<em>x</em>
<em>y</em> = number of bicycles produced
<em>x</em> = number of hours
Answer:
17.3
Step-by-step explanation:
a² = b² + c² - 2bc cos A
t² = 11² + 14² - 2(11)(14) cos 87
t² = 121 + 196 - 308 (.052336)
t² = 300.88
t = 17.3
