Ian needs to replace two concrete sections in his sidewalk, as modeled below. Each section is 36 inches by
36 inches and 4 inches deep. He can mix his own concrete for $3.25 per cubic foot. How much money will it cost Ian to replace the two concrete sections?
Answers
Answer: $19.5
Step-by-step explanation:
Hi, to answer this question we have to apply the next formula:
Volume of a rectangular prism = width x length x height
Replacing with the values given:
Since 1= 1/12 foot
36 in /12 = 3 foot (length and wifth)
4 in /12 = 1/3 foot (height)
V = 3 x 3 x 1/3 = 3ft3
Next, we multiply it by 2 (since there are 2 sections):
3 x 2 = 6 ft3
Finally we multiply it by the cost of each cubic foot:
6 x 3.25 = $19.5
Feel free to ask for more if needed or if you did not understand something.

The two plots below show the heights of some sixth graders and some seventh graders:
Two dot plots are shown one below the other. The title for the top dot plot is Sixth Graders and the title for the bottom plot is Seventh Graders. Below the line for each dot plot is written Height followed by inches in parentheses. There are markings from 52 to 57 on the top line and the bottom line at intervals of one. For the top line there are 2 dots above the first mark, 1 dot above the second mark, 1 dot above the third mark and 2 dots above the fourth mark. For the bottom line, there is 1 dot above the third mark, 1 dot above the fourth mark, 3 dots above the fifth mark and 1 dot above the sixth mark.
The mean absolute deviation (MAD) for the first set of data is 1.2 and the MAD for the second set of data is 0.8. Approximately how many times the variability in the heights of the seventh graders is the variability in the heights of the sixth graders? (Round all values to the tenths place.)

Step-by-step explanation:
Find the average rate of change of g(x)= – x2 over the interval [ – 8, – 2]. Write your answer as an integer, fraction, or decimal rounded to the nearest tenth. Simplify any fractions.
Answers
Answer:
\(Average\ Rate = 10\)
Step-by-step explanation:
Given
\(g(x) = -x^2\)
\((-8,-2)\)
Required
Determine the average rate of change;
Average rate of change is calculated as thus;
\(Average\ Rate = \frac{g(b) - g(a)}{b - a}\)
Where
\((a,b) = (-8,-2)\)
i.e. a = -8 and b = -2
\(Average\ Rate = \frac{g(b) - g(a)}{b - a}\) becomes
\(Average\ Rate = \frac{g(-2) - g(-8)}{-2 - (-8)}\)
\(Average\ Rate = \frac{g(-2) - g(-8)}{-2 + 8}\)
\(Average\ Rate = \frac{g(-2) - g(-8)}{6}\)
Calculating g(-2)
Substitute -2 for x in \(g(x) = -x^2\)
\(g(-2) = -(-2)^2\)
\(g(-2) = -4\)
Calculating g(-8)
Substitute -8 for x in \(g(x) = -x^2\)
\(g(-8) = -(-8)^2\)
\(g(-8) = -64\)
Substitute values for g(-2) and g(-8)
\(Average\ Rate = \frac{g(-2) - g(-8)}{6}\)
\(Average\ Rate = \frac{-4 - (-64)}{6}\)
\(Average\ Rate = \frac{-4 + 64}{6}\)
\(Average\ Rate = \frac{60}{6}\)
\(Average\ Rate = 10\)
Hence, the average rate of change is 10
John works as a part time waiter in a restaurant. He gets a monthly salary of ₹4,410.Calculate John’s daily, weekly and annual salary.(Take 1 month= 30 days)
Answers
1 month is aprox. 30 days, so
To find john's daily salary:
For a month, the salary is 4,410 rupees, so for a day how much?
days salary
30 4,410 (This is how I learnt to solve these kind of problems)
1 ?
Then you crisscross the equation which becomes
4,410/30=147 rupees
To find weekly salary:
we now know the salary for one day so we can say: For a day, the salary is 147 rupees, so for 7 days (1 week) how much?
You multiply the salary for one day and the number of days: 147×7=1,029 rupees
To find salary for a year (annual):
we now know the salary for one day so we can say: For a day, the salary is 147 rupees, so for 365 days (1 year) how much?
You multiply the salary for one day and the number of days: 147×365=53,655 rupees
Hope it helps!
Weekly=1,029
Yearly=53,655

B). 2, 4 and 6 only
C). 0, 2 and 4 only
D). –6, –4, –2 and 0 only
Answers
The correct option is B, 2, 4 and 6 only.
What are inequalities?Inequalities help us to compare two unequal expressions. Also, it helps us to compare the non-equal expressions so that an equation can be formed. It is mostly denoted by the symbol <, >, ≤, and ≥.
The given inequality can be simplified as shown below,
3 + (1/2)x ≥ 4
(1/2)x ≥ 4 - 3
(1/2)x ≥ 1
x ≥ (1 × 2)
x ≥ 2
Since the value of x should be greater than or equal to 2. Therefore, it can be concluded that the values of x from the options that can satisfy this inequality are 2, 4 and 6 only.

Joseph has a fair dice with 4 faces numbered 1 to 4.
He also has a fair dice with 6 faces numbered 1 to 6.
He rolls both dice.
Find the probability of rolling a different number on each dice.
Answers
Answer:
To find the probability of rolling a different number on each dice, we can determine the total number of possible outcomes and the favorable outcomes.
The total number of possible outcomes when rolling a 4-sided die and a 6-sided die is the product of the number of sides on each die: 4 × 6 = 24.
The favorable outcomes occur when we roll a different number on each die. We can calculate this by considering all the possible combinations.
For the first die (4-sided), there are 4 possible outcomes.
For the second die (6-sided), there are 6 possible outcomes.
Since we want different numbers on each die, the total number of favorable outcomes is 4 × 6 = 24.
Therefore, the probability of rolling a different number on each die is:
Probability = (Number of favorable outcomes) / (Number of total outcomes)
Probability = 24 / 24
Probability = 1
Hence, the probability is 1 or 100%.
