Answer:
a) (2.64 -2/9 -0.35 +5/8)/4
b) perform the sum, then the division, then round as needed
Step-by-step explanation:
a) The average of a number of items is their sum, divided by the number of items. Here, we want the average of 4 changes, so we compute it as the sum of the changes divided by 4.
average change = (2.64 -2/9 -0.35 +5/8)/4

b) My calculator is capable of adding these numbers directly. For a result rounded to the nearest hundredth, it can be a good idea to represent the fractions using at least 3 decimal digits.
So, the steps would be ...
- convert fractions to their decimal equivalents, using 3 decimal digits
- add up the values
- divide by 4
- round to hundredths
Performing these steps, we get ...
average change = (2.64 -0.222 -0.35 +0.625)/4 = 2.693/4
average change ≈ 0.67 . . . degrees
The average daily temperature change of a city was 0.67 degrees.
144.44 in² is the closest amount of paper she will use to wrap the gift.
Solution:
The given net is the shape of the cylinder.
Diameter of the circle = 4 in
Radius of the circle = 4 ÷ 2 = 2 in
Width of the container = 10.5 in
Length of the container is same as the circumference of the circle.
Area of the circle = 
= 
= 12.56 in²
Area of the 2 circles = 2 × 12.56 = 25.12 in²
Area of the rectangle = circumference × height
= 
= 
= 131.88 in²
Area of the net of the container
= Area of the circles + Area of the rectangle
= 12.56 in² + 131.88 in²
= 144.44 in²
Area of the net of the container = 144.44 in²
Hence 144.44 in² is the closest amount of paper she will use to wrap the gift.
Hi
24% of 80 is 19.2
100% ⇒ 80
24% ⇒ x
100x = 24·(80)
100x = 1920
x = 1920/100
x = 19.2
Answer:
No it's not!
Step-by-step explanation:
because the length (long) of J and K are totally different whereas the breadth(width) of J and K is also different which does make similar in sense
Answer:
The input (domain) are usually on the left side of the circle.
Domain = [-2, 0, 3, 4, 6]
The output (range) are usually on the right side of the circle.
Range = [-3, -2, 0, 1, 2, 4]
Since the domain of 3 is pointing at two ranges (3, 4) and (3, -3), the x value repeats.
Functions do not have repeating x values.
The picture shown is not a function.
