Answer: a) What is a good scale to use for the y axis? -20 units.
(b) What is a good interval to use for the y axis?- 20 units
Step-by-step explanation:
A family is tracking its spending habits. Over the
past year, the grocery bill has ranged from $120 to $180.
We need to plot these points on a coordinate grid.
If we plot the grocery bills along the y-axis, and past years will be plotted along the x-axis.
So, a) Good scale to use for the y-axis will be
1 scale = 20 units
As 120 and 180 are both divisible by 20.
So, it will be a good scale to use for the y-axis.
b) Good interval to use for the y-axis:
It will be again of 20 units.
Answer:
with what exactly
Step-by-step explanation:
Answer:
80 persons haf fish and 152 persons had chicken
Step-by-step explanation:
Given data
let the number of persons that had fish be x and chicken be y
so
12x+9y=2544------------------1
x+y= 232------------------------2
from 2
x= 232-y
substitute the value of x in 1
12(232-y)+9y=2544
2784-12y+9y=2544
2784-3y=2544
3y= 2784-2544
3y=240
y= 240/3
y=80
put y= 80 in 2
x+80= 232
x= 232-80
x=152
Hence 80 persons haf fish and 152 persons had chicken
Answer:
You need to use appropriate formula for the surface area. You may find formula in your mathematics book.
Answer:
A≈706.86ft²
Step-by-step explanation:
A=πr2=π·152≈706.85835ft²
rounded two decimal places= 706.86
