How can you use a bar diagram to check the accuracy of the solution to a ratio or rate problem<span>? ... To see which bar is higher... the higher the bar the soloution if the ratio ... If the ratio of problems she finished to problems she still had left was 8 : 1, how many homework problems did she have total?</span>
Answer:
23.274
Step-by-step explanation:
Here, rounding to the nearest thousandth means rounding to the nearest 0.001.
Hence, due to the digit being rounded having a number larger than 5 after it (0.2736), it is rounded up.
Hope this helped!
Answer: y = -1/4 * x - 4
Explanation:
Slope intercept form : y = mx + b
m = slope & b = y intercept
y = mx + b
y = -1/4(x) + b
y = -1/4(x) - 4
-1/4 is slope
-4 is y intercept
Answer:
Step-by-step explanation:
Given
See attachment for model
Required
Determine 
from the model
The model is represented by:
To get: 
, we consider the first partition
The number of shaded box is 63 ---- this represents the denominator
The total boxes shaded at the bottom is 36 ---- this represents the numerator
So, we have:
To get: , we consider the first partition
The number of shaded box is 63 ---- this represents the denominator
The total boxes shaded at the bottom is 16 (do not count the gray boxes) ---- this represents the numerator
So, we have:
The equation becomes:
