A food manufacturer makes 32-oz boxes of pasta. not every box weighs exactly 32 oz. The allowable difference from the ideal weight is at most 0.05 oz. Write and solve an absolute value inequality to find the range of allowable weights.
I will give brainliest
Answer:
The range of allowable weights is between 31.95 oz and 32.05 oz both included
Step-by-step explanation:
w= allowable weights
I w-32 I ≤ 0.05
-0.05 ≤ w-32 ≤0.05
31.95 ≤ w ≤ 32.5
The range of allowable weights is lies between 31.95 ≤ w ≤ 32.5
What is a solution set to an inequality or an equation?If the equation or inequality contains variable terms, then there might be some values of those variables for which that equation or inequality might be true. Such values are called solution to that equation or inequality. Set of such values is called solution set to the considered equation or inequality.
We are given that food manufacturer makes 32-oz boxes of pasta. not every box weighs exactly 32 oz.
The allowable difference from the ideal weight is at most = 0.05 oz.
Let w= allowable weights
Then we have;
I w-32 I ≤ 0.05
-0.05 ≤ w-32 ≤0.05
31.95 ≤ w ≤ 32.5
Thus, range = 31.95 ≤ w ≤ 32.5

A swordfish can swim at a rate of 60 miles per hour. How many feet per hour is this? The Shinkansen passenger train of Japan travels at a rate of 300 kilometers per hour. How many meters per hour is this speed?
Answer:
that is 316, 800 feet per hour for the swordfish
and 300,000 meters per hour for the passenger train
Step-by-step explanation:
multiply 60 by 5,280 because there are 5,280 feet in a mile
multiply 300 by 1000 because there are 1000 meters in a kilometer *hence the prefix kilo

Which term best describes the graph of y = –2?
increasing
decreasing
constant
positive
Answer:
It would be constant.
Step-by-step explanation:
Since there is no x value, the line will have no slope and just be horizontal about y= -2.
If we draw the graph we will see that the function is a straight line parallel to the x-axis.
The graph y = -2 is best described as a constant function.
Option C is the correct answer.
What are coordinates in a graph?The coordinates in a graph indicate the location of a point with respect to the x-axis and y-axis.
The coordinates in a graph show the relationship between the information plotted on the given x-axis and y-axis.
We have,
A function:
y = -2
To graph the function we will find the coordinates of the function y = -2.
For x = 0,
y = -2
For x = 1,
y = -2
For x = 2,
y = -2
For x = 3,
y = -2
We will see that for all x values the y value is -2.
If we draw the graph we will see that the function is a straight line parallel to x-axis.
Thus,
The graph y = -2 is best described as a constant function.

Solve 7(y + 2) – (4y – 10) = 44 – 2y + 5
A.y = -5
B.y = 5
C.y = -10
Answer:
y = 5
Step-by-step explanation:
7(y + 2) – (4y – 10) = 44 – 2y + 5
(7y+14) - (4y - 10) = 49 -2y
3y +24 = 49 -2y
5y +24 = 49
5y = 25
y = 5
Answer:
y=5
Step-by-step explanation:
7(y+2)-(4y-10) = 44-2y+5 distribute on the left and combine like terms on the right side of the equation
7y + 14 -4y +10 = 49 - 2y move every term with a variable on the left side with a change sign and the numbers on the right side
7y-4y+2y =49 -14 -10
5y = 25 divide both sides by 5
y5/5=25/5 so
y=5

The following shows the process a student used to determine the number of yards in 3,218 meters.
(1 mile = 1,609 meters)
(1 mile = 1,760 yards)
Step 1: 1,609 meters is being multiplied by conversion factor 1 mile over 3,218 meters equals 0.5 mile
Step 2: 0.5 mile is being multiplied by conversion factor 1760 yards over 1 mile equals 880 yards
Step 3: 880 yards
What was the error made in this conversion?
The 1 mile and 3,218 meters in Step 1 should be switched.
The 1,609 meters and the 3,218 meters in Step 1 should be switched.
The conversion factor should be added in Step 2 instead of being multiplied.
The conversion factor should be divided in Step 2 instead of being multiplied.
