Answer:
For the first one, you get x<7.
For the second one, you get x >_ 11
Step-by-step explanation:
For the first one: -2x - 2 > -16
Step 1. Add 2 to both sides.
-2x - 2 +2 > -16 + 2
-2x > -14
Step 2. Divide both sides by -2 and switch the sign
-2x/-2 > -14/-2
x < 7
For the second one: 2x - 1 >_ 21
Step 1: Add 1 to both sides
2x -1 +1 >_ 21 + 1
2x >_ 22
Step 2: Divide both sides by 2
2x/2 >_ 22/2
x >_ 11

You are paid 1.5 times your normal hourly rate for each hour you work over 40 hours in a week. You worked 46 hours this week and earned $612.50.
Part A: Which equation can you use to solve for x , your normal hourly rate?
Part B: What is your normal hourly rate?
Answers
Part B: 12.5
Distribute the xs so you get 40x+9x=612.50. Then divide 612.50 by 49 to get x.
Equation that represents the given situation is 40x + 6 *1.5x = 612.50.
What is Linear function?A linear function in mathematics is one that has either one or two variables and no exponents. It is a function with a straight line as its graph.
Given, You are paid 1.5 times your normal hourly rate for each hour you work over 40 hours in a week. You worked 46 hours this week and earned $612.50.
First, define the variables. Let’s let x = his regular pay.
For first 40 hours pay = 40x
Over time pay = 1.5x
Since he worked 46 hours
Thus his over time pay = (46 -40) *1..5x
Thus his over time pay = 6 * 1.5x
Since, You worked 46 hours this week and earned $612.50.
linear equation that represents the given situation
40x + 6 *1.5x = 612.50
Normally hourly rate:
40x + 9x = 612.50
49x = 612.50
x =12.5
Therefore, Equation that represents the given situation is 40x + 6 *1.5x = 612.50.

Banana Cupcakes
makes 10 cupcakes
1 cup granulated sugar
cup vegetable oil
1 large egg
4 tablespoons sour cream
2 medium-sized ripe bananas, mashed
1 cups all-purpose flour
1 teaspoon baking soda
teaspoon salt
1 teaspoon vanilla extract
pinch of nutmeg
You will use the recipe above to answer the following questions:
This recipe serves 10, but you need to serve 30. What number will you need to multiply the amount of each ingredient by to adjust the recipe? How did you determine this number?
How much vegetable oil do you need for 30 cupcakes?
How much flour do you need for 30 cupcakes?
What is the difference in the amount of vanilla extract you would need for 30 cupcakes?
What is the difference in the amount of salt you would need for 30 cupcakes?
In the real world, even though you make adjustments to a recipe to accommodate the number of people you need to serve, you sometimes round the amount of an ingredient instead of using an exact amount. Which ingredient would it make more sense to round rather than coming up with the exact amount? Why?
Answers
Answer: Hey give me 1 hour and ill answer it I'm doing odessyware rn so Ill get back to you later appreciate yo patients.
Step-by-step explanation:
Then, if we want to make 30 servings, we need to use that recipe 3 times. (because x*10 = 30, then x = 30/10 = 3)
This would be equivalent to multiply each ingredient by 3.
for 30 cupcakes we need:
3 cups of vegetable oil.
3 cups of all-purpose flour
(because for each one of these ingredients we needed only 1 cup to make 10 cupcakes).
for 10 cupcakes we need 1 teaspoon of vanilla.
for 30 cupcakes we need 3 teaspoons of vanilla, the difference is 3 - 1 = 2.
So the difference is 2 teaspoons.
About which quantities we should round are those where we may have mixed numbers or big numbers.
For example, we have 4 tablespoons of sour cream for 10 servings, then for 30 servings we should have:
3*4 = 12 tablespoons.
We could round this down to 10 tablespoons.

The expression 2x + 4x represents the cost of buying the same number of cases of spring water, sold for $2 per case, and sparkling water, sold for $4 per case. What expression can be used to express the total cost?
Answers
Answer: 2x + 4x = (2 + 4)x = 6x
Step-by-step explanation:
The expression 2x + 4x represents the cost of buying the same number of cases of spring water and sparkling water. To express the total cost, we need to add the cost of buying the two types of water.
Since the expression 2x represents the cost of buying x cases of spring water, and 4x represents the cost of buying x cases of sparkling water, the total cost can be expressed as:
2x + 4x = (2 + 4)x = 6x
Therefore, the total cost of buying x cases of spring water and sparkling water can be expressed as 6x.
Alternatively, you can think of it as buying x cases of spring water at a cost of 2x dollars and x cases of sparkling water at a cost of 4x dollars. So the total cost is (2x+4x) dollars which is 6x dollars.

Given:
A = $5,000P = $4,000r = 5% = 0.05Substitute the given values into the formula and solve for t:
\(\implies 5000=4000(1+0.05t)\)
\(\implies \dfrac{5000}{4000}=1+0.05t\)
\(\implies1.25=1+0.05t\)
\(\implies 0.05t=1.25-1\)
\(\implies 0.05t=0.25\)
\(\implies t=\dfrac{0.25}{0.05}\)
\(\implies t=5\; \rm years=60\; months\)
Given:
A = $11,160r = 8% = 0.08t = 36 months = 3 yearsSubstitute the given values into the formula and solve for P:
\(\implies 11160=P(1+0.08 \cdot 3)\)
\(\implies 11160=P(1.24)\)
\(\implies P=\dfrac{11160}{1.24}\)
\(\implies P=\$9000\)
Given:
A = $3,207P = $3,000t = 18 months = 1.5 yearsSubstitute the given values into the formula and solve for r:
\(\implies 3207=3000(1+r \cdot 1.5)\)
\(\implies \dfrac{3207}{3000}=1+1.5r\)
\(\implies 1.069=1+1.5r\)
\(\implies 1.5r=1.069-1\)
\(\implies 1.5r=0.069\)
\(\implies r=\dfrac{0.069}{1.5}\)

Answers
For Mountain View School:
Data: 0, 0, 0, 0, 1, 2, 3, 4, 4, 5, 5, 5, 5, 6, 7, 8, 8, 8, 9
Mean: (0 + 0 + 0 + 0 + 1 + 2 + 3 + 4 + 4 + 5 + 5 + 5 + 5 + 6 + 7 + 8 + 8 + 8 + 9) / 19
= 100 / 19
≈ 5.26
To find the median, we need to arrange the data in ascending order: 0, 0, 0, 0, 1, 2, 3, 4, 4, 5, 5, 5, 5, 6, 7, 8, 8, 8, 9.
The median is the middle value, which is the 10th value in this case.
Median: 5
For Seaside School:
Data: 0, 0, 0, 1, 1, 2, 2, 4, 5, 5, 5, 5, 6, 7, 7, 8, 8, 8, 9
Mean: (0 + 0 + 0 + 1 + 1 + 2 + 2 + 4 + 5 + 5 + 5 + 5 + 6 + 7 + 7 + 8 + 8 + 8 + 9) / 19
= 80 / 19
≈ 4.21
To find the median, we need to arrange the data in ascending order: 0, 0, 0, 1, 1, 2, 2, 4, 5, 5, 5, 5, 6, 7, 7, 8, 8, 8, 9.
The median is the middle value, which is the 10th value in this case.
Median: 5
Now let's calculate the measures of variability, specifically the range and interquartile range (IQR).
Range: The range is the difference between the largest and smallest values in the dataset.
For Mountain View School:
Range: 9 - 0 = 9
For Seaside School:
Range: 9 - 0 = 9
Interquartile Range (IQR): The IQR is the difference between the third quartile (Q3) and the first quartile (Q1) and measures the spread of the middle 50% of the data.
For Mountain View School:
Q1 = 3
Q3 = 7
IQR = Q3 - Q1 = 7 - 3 = 4
For Seaside School:
Q1 = 2
Q3 = 7
IQR = Q3 - Q1 = 7 - 2 = 5
To determine which school is a better choice for a smaller class size, we can consider both the mean and the median.
Both the mean and median for Mountain View School are higher than those for Seaside School. This suggests that, on average, the class sizes at Mountain View School are larger than those at Seaside School. Therefore, if you are interested in a smaller class size, Seaside School would be a better choice
For Mountain View School:
- Median: The median class size is the middle value, which is 25.
- Mean: The mean class size is the sum of all the class sizes divided by the total number of classes, which is (29 + 28 + 28 + 27 + 25 + 24 + 24 + 23 + 21 + 20 + 19 + 18 + 15 + 13 + 10) / 15 = 21.27.
For Seaside School:
- Median: The median class size is the middle value, which is 20.
- Mean: The mean class size is the sum of all the class sizes divided by the total number of classes, which is (25 + 25 + 27 + 27 + 28 + 28 + 28 + 30 + 31 + 35 + 36 + 38 + 40 + 43 + 45) / 15 = 31.13.
Part B:
For Mountain View School:
- Range: The range is the difference between the largest and smallest values, which is 29 - 10 = 19.
- Interquartile Range (IQR): The IQR is the difference between the third quartile (Q3) and the first quartile (Q1). From the stem-and-leaf plot, we can see that Q1 is 20 and Q3 is 28. Therefore, the IQR is 28 - 20 = 8.
For Seaside School:
- Range: The range is the difference between the largest and smallest values, which is 45 - 25 = 20.
- Interquartile Range (IQR): The IQR is the difference between the third quartile (Q3) and the first quartile (Q1). From the stem-and-leaf plot, we can see that Q1 is 27 and Q3 is 38. Therefore, the IQR is 38 - 27 = 11.
Part C:
If you are interested in a smaller class size, Mountain View School is a better choice for you because it has a lower mean and median class size than Seaside School.

Situation D: A worker earned $23.66 Monday and spent $15.84 Tuesday.
Calculate the sum of each situation. Order the situations from least to greatest based on the numeric value of the sums.
Answers
Answer:
Step-by-step explanation:Situation A: The hang glider descended 33.57 feet and again ascended 14.98. So 33.57 - 14.98 = 18.58. So now the hang glider is at 18.58 feet
Situation B: Initially they gained 7 2/5 yards and then lost 3/5 yards.
7 2/5 yards can be written as 37/5. As they lost 3/5 yards, 37/5 - 3/5 = 34/5. So the remaining yards are 34/5 yards.
Situation C: Hiker walked 3 1/6 miles and then 2 1/2 miles. So the total distance is 3 1/6 + 2 1/2 = 5 4/6 miles.
Situation D: Total amount earned is $23.66 + $15.84 = $39.5.

Keira said that if 6 tickets are sold, there should be 2 tickets left. Is Keira correct?
Answers
According to Keira, if 6 tickets are sold, there should be 2 tickets left. However, we don't have any information about the initial number of tickets available.
If the total number of tickets initially was 8, and 6 tickets were sold, then there would indeed be 2 tickets left, supporting Keira's statement.
However, if the total number of tickets initially was less than 8, or if the statement doesn't specify the initial number of tickets, we cannot determine if Keira's statement is correct.
Therefore, without additional information, we cannot determine the accuracy of Keira's statement.
