Average price of a CD/ mp3 player is : $ 150
Meanwhile , average price of an mp3 player is : $50
To buy 4 cd/mp3 player, we need $ 150 x 4 = $ 600
To but an mp3 player, we need $50 x 3 = $ 150
The total is $ 750
Hope this helps
Answer:
1st option
Step-by-step explanation:
For any input of value <em>x</em>, the output <em>y </em>is always 2. The equation would then be y = 2, which would have 0 slope.
Answer:
I think this is right? The instructions seem a bit vague to me...
Condition A: Many
Condition B: One
Condition C: One
Condition D: Many
Condition E: Many
Condition F: One
Step-by-step explanation:
So Condition A: A rectangle with 4 right angles is going to be in many quadrilaterals because squares are also a rectangle with 4 right angles. So condition A has 2 or maybe more that I forgot about.
Condition B: A square with one side measuring 5 inches is one quadrilateral. Squares are one specific type of quadrilateral so they're probably going to go into one quadrilateral
Condition C: A rhombus can sometimes also be a square, but since in this case, it's angle is only 43°, it should be one quadrilateral.
Condition D: There are a lot of parallelograms. Just because one angle is 32°, it doesn't mean there is just one. There are rhombuses and trapezoids that have 32° angles that would be parallelograms. This one is many.
Condition E: This one was hard for me to visualize, but I'm pretty sure this one is also many. There are at least 2. One side could be 6 inches and another could be 8 inches and then, it could be vice versa, so there are probably more than one. This one is many.
Condition F: Is this even possible? I think it's one.
101.15
Explanation:
140 x 7.25% = 10.15
140 x 35% = 49
Then we add the tax and subtract the sale :
140 + 10.15 - 49 = 101.15$
Hope it’s right
Best luck with your studying
