Sophia works in a clothing store and earns $40 per day. She earns an extra $5 for each outfit she sells. If Sophia wants to earn at least $70 per day, which inequality shows the minimum number of outfits, n, that she should sell? (5 points)
Select one:
a. 40 + 5n ≤ 70, so n ≤ 6
b. 40 + 5n ≥ 70, so n ≥ 25
c. 40 + 5n ≤ 70, so n ≤ 25
d. 40 + 5n ≥ 70, so n ≥ 6
Answer:
I think the answer is B.

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

A 50-centimeter piece of wire is bent into a circle. What is the diameter of the circle? What is the radius of the circle? What is the area of the circle?
Answer:
The diameter will be given by 50 cm ÷ 3.142 = 15.9134 cm
The radius will be 15.9134 ÷2 = 7.9567 cm or about 7.96 cm
The area of a circle is given by \pi × square of radius
Area = 3.142 × 7.96×7.96 = 199.0821 square cm
Answer:
the diameter would be half of the original length because it needs to be a circle so each half of the circle would equal 25 centimeters

Answer:
I'll list the answers as coordinates (just input the second number in each coordinate)
(-2, 11)
(0, 1)
(2, -9)
(4, -19)
Step-by-step explanation:
So you see how the x column is filled out? You plug in the numbers in each area and solve for y.
So we start off with -2. You take the x out and place -2 instead. Your equation should look like this:
y = -5 (-2) + 1
Next you multiply -5 and -2, giving you 10. Your equation would look like this now:
y = 10 + 1
Next you add 10 and 1 together, and you have your answer. Keep doing the same thing, but instead of -2 for x, use 0, 2, and 4.
Hope I helped! Have a nice day or night! ^-^

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.

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
