Answer:
266
Step-by-step explanation:
Let the attendence of 5days be a,b,c,d,e
given,
(a+b+c+d+e)/5=264
a+b+c+d+256=264*5 [since 5th day=256]
(a+b+c+d+)/4=1(320-256)/4 [dividing both side by 4]
average attendence of 4 days =266
Answer:
Step-by-step explanation:
Fraction of sugar in 60 gram cereal = 1/4
1/4 parts means that if 60 gram sugar is divided into four parts then out of that one part is sugar.
Amount of sugar in cereal in grams = 1/4 of 60 gram
Amount of sugar in cereal in grams = 1/4 * 60 gram = 15 grams.
Therefore, 15 grams sugar is in a 60 gram serving converted.
The answer is a if the line is dotted/dashed. The answer is c if the line isn't dotted/dashed.
What grade is this? I can get the answer of it but I forgot how
So that is equal to 180 miles per 2 hours which is 90 miles per hour if each hour has the same m/hr rate.
You can set up a proportion:
let x = number of miles per hour

cross multiply and you get
2x=180
divide both sides by 2 and you get
x=90
so you get the same answer both ways,
90 miles per hour
