The science club raised money to clean the beach. They spent $29 on trash bags and $74 on waterproof boots. They still have $47 left. How much did they raise?
Answer:
They raised $150
Step-by-step explanation:
In order to solve this you just need to reverse the actions that they took in order to get to 47 dollars left, so the total amount they raised will be represented by letter X, so 47 is what is left after spending 29 on trash bags and 74 on waterproof boots, that means that from the total we are withdrawing those amounts and the result will be 47:
Total-Money spent=47
X-29 - 74= 47
x=47+74+29
x=150
So now we know that they originally had 150 dollars and that would be what they raised.

What is a place value?
Place value is the value of each digit in a number.
Example: 2345.67
2 – thousands place value
3 – hundreds place value
4 – tens place value
5 – ones place value
6 – tenths place value
7 – hundredths place value
We have,
43 ones x 3 tens
43 ones can be written as 43
3 tens can be written as 30
So,
43 ones x 3 tens = 43 x 30
43 x 30 = 1290
This means,
1290 = 129 tens
43 ones x 3 tens = 129 tens
Thus,

Danny “Dimes” Donahue is a neighborhood’s 9-year old entrepreneur. His most recent venture is selling homemade brownies that he bakes himself. At a price of $1.75 each, he sells 100. At a price of $1.25 each, he sells 300.
a. The elasticity of demand is 0.0225.
b. Demand is inelastic over this price range.
c. Total revenue would increase due to the more elastic demand resulting in a greater quantity demanded with a price decrease.
Let's first calculate the price elasticity of demand using the midpoint method:
a. Price elasticity of demand formula:
[tex]\[ E_d = \frac{\text{Percentage change in quantity demanded}}{\text{Percentage change in price}} \times \frac{\text{Average price}}{\text{Average quantity}} \][/tex]
Percentage change in quantity demanded:
[tex]\[ \text{Percentage change in quantity demanded} = \frac{300 - 100}{\frac{300 + 100}{2}} \times 100\% = \frac{200}{200} \times 100\% = 100\% \][/tex]
Percentage change in price:
[tex]\[ \text{Percentage change in price} = \frac{1.25 - 1.75}{\frac{1.25 + 1.75}{2}} \times 100\% = \frac{-0.5}{1.5} \times 100\% = -33.33\% \][/tex]
Average price and average quantity:
[tex]\[ \text{Average price} = \frac{1.25 + 1.75}{2} = \frac{3}{2} = 1.50 \]\[ \text{Average quantity} = \frac{300 + 100}{2} = \frac{400}{2} = 200 \][/tex]
Now, we can plug these values into the elasticity formula:
[tex]\[ E_d = \frac{100\%}{-33.33\%} \times \frac{1.50}{200} \]\[ E_d = -3 \times 0.0075 \]\[ E_d = -0.0225 \][/tex]
a. The elasticity of demand is 0.0225.
b. Since the elasticity of demand is less than 1, demand is inelastic over this price range.
c. If demand had the same elasticity for a price decline from $1.25 to $0.75 as it does for the decline from $1.75 to $1.25, cutting the price from $1.25 to $0.75 would increase Danny's total revenue because the demand would be more elastic, resulting in a greater increase in quantity demanded compared to the decrease in price.

When twotwo basketball players are about to have a free-throw competition, they often draw names out of a hat to randomly select the order in which they shoot. what is the probability that they shoot free throws in alphabetical order? assume each player has a different name?
Final answer:
The probability of shooting free throws in alphabetical order is 0.5.
Explanation:
Probability of shooting free throws in alphabetical order:
Determine the total number of ways the players can shoot. There are 2 players, so 2! (2 factorial) = 2 ways.
Calculate the number of ways they can shoot in alphabetical order. As they have different names, only 1 way exists.
Probability = (Number of ways shooting in alphabetical order) / (Total number of ways to shoot) = 1/2 = 0.5.

A scientist has four petri dishes of different sizes. Each dish contains a different number of bacteria. Find each population density, to the nearest hundredth. Which statement is true? Dish A has the lowest population density. Dish C has the greatest population density. Dish A and Dish B have approximately the same population density. Dish C and Dish D have approximately the same population density.
The statement that is True is Option D which says:
"Dish C and Dish D have approximately the same population density."
What is Population Density?The population density of an area is the Number of Entities in that space/Total Area occupied by the population.
It can also be written as Dp = N/A.
Because the Dp of Dish C and Dish D is approximately 0.68, we can say that they have approximately the same Dp.

Write a rule for the linear function in the table.
x; f(x)
2 8
5 17
5 11
11 23
A; f(x) = x + 5
B;f(x) = x + 1
C;f(x) = 2x + 1
D;f(x) = –2x – 1
the correct answer is A. [tex]\( f(x) = 2x + 1 \).[/tex]
To find the rule for the linear function represented in the table, we can use the formula for a linear function, which is:
[tex]\[ f(x) = mx + b \][/tex]
Where:
- m is the slope of the line
- b is the y-intercept
Given the table:
[tex]\[ \x & : 2, 5, 8, 11 \\f(x) & : 5, 11, 17, 23\end{align}\][/tex]
We can start by finding the slope (m) using the formula:
[tex]\[ m = \frac{{f(x_2) - f(x_1)}}{{x_2 - x_1}} \][/tex]
Let's choose two points from the table, for example, (2, 5) and (5, 11):
[tex]\[ m = \frac{{11 - 5}}{{5 - 2}} \]\[ m = \frac{{6}}{{3}} \]\[ m = 2 \][/tex]
So, we have found that the slope m is 2.
Now, we can use the slope-intercept form of a line to find the y-intercept (b). We can pick any point from the table to do this. Let's use the point (2, 5):
f(x) = mx + b
5 = 2(2) + b
5 = 4 + b
b = 5 - 4
b = 1
So, we have found that the y-intercept b is 1.
Now, we can write the rule for the linear function:
[tex]\[ f(x) = 2x + 1 \][/tex]
Therefore, the correct answer is A. [tex]\( f(x) = 2x + 1 \).[/tex]
The complete question is:

Must a function that is decreasing over a given interval always be negative over that same interval ? Explain
Answer:
For a function to be decreasing over an interval, the outputs on the function are getting smaller as the inputs of the function are getting larger, but the outputs could be positive or negative. For a function to be negative over an interval, the outputs must be negative, while the inputs could be positive or negative.

find the missing values in the ratio table .then write the equivalent ratios .
The missing values are 12 and 18.
