Answer:
Step-by-step explanation:
If <em>t</em> is years since January 1, 2010, then on January 1, 2010, <em>t</em> = 0.
On April 1, 2010, there are 3 months from January 1, 2010. <em>t</em> = 0.25 (3 months ÷ 12 months)
At <em>t</em> = 0, <em>P</em>(<em>t</em>) = 500
At <em>t</em> = 0.25, <em>P</em>(<em>t</em>) = 750
Substituting for <em>B</em> and <em>k</em> in <em>P</em>(<em>t</em>),
14 degrees. It equals half the intercepted arc.
(See attached graphic)
it's a quadrilateral
interior angles add up to 360
x + 2x - 75 + x + x - 35 = 360
5x - 110 = 360
5x = 360 + 110
x = 470 ÷ 5
x = 95
and x - 35 = 60
2x - 75
= 190 -75
= 115
We are given here the individual costs of DVD and CD as well as the total sales and the number of items sold on one day. To solve the number of DVDs and CDs sold each, we devise two independent linear equations:
(1) x + y = 39
(2) 4x + 7y = 204
x- number of DVDs; y - number of CDs
solving, x= 23 DVDs
X=number of the chairs y=the total cost of chairs
150/50=3$ y=3x
