Answer:
1/4 ; $28.25
Step-by-step explanation:
Given the following :
Cost of stationeries:
Pencil:$1.20
Eraser:$1
Ruler:$0.50
Total : $169.50
Let total Stationeries purchased = t
Fraction of pencils = 1/3t
Remainder = t - 1/3 = 2/3t
Fraction of eraser = 5/8 of remainder
Thus ;
Fraction of eraser = 5/8 * (2/3)t= 10/24 = (5/12)t
Rest were ruler ;
(2/3)t - (5/12)t= (8 - 5)/12
= 3 / 12 = 1/4t
Fraction of rulers = 1/4
Amount spent on erasers:
(5/12) of the total cost of stationery
(5/12) * 169.50 = $70.625
B.) How much more did she spend on erasers than rulers
Amount spent on rulers :
(1/4) * $169.50 = $42.375
Take the difference :
$(70.625 - 42.375) = $28.25
Answer:
(1/4 , 19/8)
Step-by-step explanation:
Rewrite in standard form and use this form to find the vertex (h,k)
Slope is rise/ run and rise/run is y/x. c?
I think it is 1.3 and how u figure it out is tenths and haves charts like me
This has alot of information missing. Can you please repost this with more detailed information? Thanks.
