Answer:
C
Step-by-step explanation:
Answer:
a. Inscribed angle = <WXY
b. Minor arc = arc(XY)
c. VWX
d. m(VWX) = 180°
e. m<VUW = 110°
Step-by-step explanation:
a. The angle, <WXY has its vertex on the circumference of the circle. Therefore, it can be referred to as an inscribed angle of the circle with center U.
Inscribed angle = <WXY
b. Arc(XY) is a minor arc because it is smaller than half of circle with center U.
Minor arc = arc(XY)
c. A semicircle is half of a full rotation for a circle. From the diagram, a semicircle is VWX
d. m(VWX) = Half the rotation of a full circle = 180°
e. m<VUW = arc(VW) (measure of central angle = measure of arc)
m<VUW = 110° (Substitution)
First, convert the 33% to a real mathematical number. For percents, this is always done by dividing the 33% by 100%, or 33% / 100% = 0.330.
Second, find out what 33% of $2799 is. This is the amount of the sale discount. This is always found by mulitplying 0.330 by the item's cost $2799, like this:
0.330 x $2799 = $923.67.
So for this sale, you'll save $923.67 on this item.
This means, the cost of the item to you is
$2799 - $923.67 = $1875.33.
Alternatively, you can think about it this way. The item is 33% off. This means you'll pay 67.000% of the total cost (100% - 33% = 67.000%).
Now what's 67.000% of the total cost?
0.670 x $2799 = $1875.33.
Just like the result above, the sale price on the item is $1875.33.
Hope this helps you on your assignment! :)

Answer: the number of new light bulbs that they put in is 36
Step-by-step explanation:
The Marino's put new light bulbs in all the fixtures the new house.
Each fixture used 2 light bulbs and each room had 3 fixtures. This means that the number of bulbs in each room would be 3×2 = 6 bulbs.
The new house had 6 rooms. This means that the total number of bulbs in 6 rooms would be
6 × 6 = 36 bulbs
