Last summer, Jesse’s family drove to visit his grandmother. Jesse kept track of how far they drove each day. Monday: 242 mi. Tuesday: 324 mi. Wednesday: 212 mi. Thursday: 363 mi. Friday: 132 mi.
Use front-end estimation to find a reasonable estimate of the total distance Jesse’s family traveled.
A) 1000 mi.
B) 1100 mi.
C) 1200 mi.
D) 1300.
Answers
The correct option is C 1200 mi. A reasonable estimate of the total distance Jesse's family traveled is 1200 mi.
Front-end estimation involves rounding numbers to the nearest place value and then performing calculations. Round each day's distance to the nearest hundred to simplify calculations.
Round each day's distance: Monday 200, Tuesday 300, Wednesday 200, Thursday 400, Friday 100.
Add the rounded distances:
200 + 300 + 200 + 400 + 100 = 1200.
The estimate of the total distance traveled is 1200 miles, which matches option C.
Front-end estimation is a quick method for approximate calculations, especially when precise values are not required.

Brayden conducted a scientific experiment. For a certain time, the temperature of a compound rose 2 2/5 degrees in 1/5 of an hour. How much did the temperature of the compound rise in one hour?
Answers
Answer: 12 degrees or 11 5/5 or 60/5
Step-by-step explanation:
Since the temperature is rising 2 2/5 per 1/5 of an hour we just need to multiply 2 2/5 times 5 because 5/5 would equal the whole hour. In order to multiply easier you can change 2 2/5 to an improper fraction by multiplying the whole number with the denominator and then adding the numerator. Which you should get 12/5 next change 5 to a fraction which would be 5/1. 5 times 12 is 60 and 5 times 1 is 5. You get 60/5 which if divided is 12.
For the number line you just have to find 1/5 and 2 2/5 on it and mark it.

Answers
Answer:
The decrease of the decimal rate -1.05 mm/year can be rounded to -1. You don’t need to round 2.48 because you’re multiplying by -1. Since -1.05 is negative and rounded to a greater value, the estimate could be adjusted to a slightly lesser value, maybe -2.5 or -2.6.

For five days, Diego recorded the lengths, in minutes, of his walk to school. The mean for his data is 11 minutes. Determine which data set below is Diego’s, and prove that your choice is correct.
Answers
Data Set A: 9, 11, 13, 10, 12
Data Set B: 8, 10, 12, 14, 16
Data Set C: 10, 10, 10, 10, 10
Data Set D: 11, 11, 11, 11, 11
To find the mean, we sum up all the values in each data set and divide by the number of values:
Data Set A: (9 + 11 + 13 + 10 + 12) / 5 = 11 minutes
Data Set B: (8 + 10 + 12 + 14 + 16) / 5 = 12 minutes
Data Set C: (10 + 10 + 10 + 10 + 10) / 5 = 10 minutes
Data Set D: (11 + 11 + 11 + 11 + 11) / 5 = 11 minutes
Comparing the mean of each data set to 11 minutes, we can see that only Data Set A and Data Set D have a mean of 11 minutes. However, to prove that our choice is correct, we need to analyze the individual values in the data set.
In Data Set A, we can observe that the values are relatively close to 11 minutes, with some values slightly above and below. This variation suggests a realistic scenario where Diego's walk to school might take slightly different amounts of time each day.
In Data Set D, all the values are exactly 11 minutes. While it is not impossible for Diego's walk to consistently take exactly 11 minutes each day, it seems less likely than having some variation in the durations.
Based on these observations, we can conclude that the most plausible data set for Diego is:
Data Set A: 9, 11, 13, 10, 12
This data set has a mean of 11 minutes and exhibits a realistic variation in walk durations, making it the most likely choice for Diego's recorded lengths.

Step-by-step explanation:
Large rectangle:

Find leftover area:
756-180
=576 ft²
Hope this helps! :)
Answer:
The area that is left for development in the field outside the playground is 576 ft².
Step-by-step explanation:
To calculate the area left for development in the field outside the playground, we need to subtract the area of the smaller rectangle from the area of the larger rectangle.
The area of a rectangle is the product of its width and length:
\(\boxed{\sf Area\;of\;a\;rectangle=width \times length}\)
The dimensions of the larger rectangle are:
width = 21 ftlength = 36 ftThe dimensions of the smaller rectangle are:
width = 15 ftlength = 12 ftTherefore, the development area can be calculated as follows:
\(\begin{aligned}\sf Development \;area&=\sf Area_{large\;rectangle}-Area_{small\;rectangle}\\\\&=(21 \times 36)-(15 \times 12)\\\\&=756-180\\\\&=576\; \sf ft^2\end{aligned}\)
Therefore, the area that is left for development in the field outside the playground is 576 ft².

Answers
Answer:
(9 × 100) + (2 × 1) + (6 × 0.1) + (4 × 0.001)
Step-by-step explanation:
(9 × 100) + (2 × 10) + (6 × 110) + (4 × 1100) = 900 + 20 + 660 + 4400
900 + 20 + 660 + 4400 = 5980
(9 × 100) + (2 × 1) + (6 × 110) + (4 × 1100) = 900 + 2 + 660 + 4400
900 + 2 + 660 + 4400 = 5962
(9 × 100) + (2 × 1) + (6 × 110) + (4 × 11000) = 900 + 2 + 660 + 44000 = 45562

Your A value (-1) multiplies by everything inside of the parentheses.
-x+5=0
You move your constant (5) to the right side of the equation and flip the sign from a positive 5 to a negative 5.
-x=5 (5 + 0 just equals 5)
To get rid of the negative sign on the X, divide both sides of the equation by -x.
The answer would be:
x=5
You can repeat this process for other similar equations.
To turn equations into distributive form, follow these steps:
I see you gave me an equation with 5x + 11x. Remember, we are trying to get an A value and parenthesis. To do this, we need to find the GCF (Greatest common factor). Ex: If you were putting 5+10 in distributive form, the GCF would be 5, because five is the greatest common factor between 5 and 10, meaning it's the greatest possible number that goes into 5 (1 time) and 10 (2 times).
Although, there is no GCF in 5x+11x, but there are two common X values, so this may be put into distributive property such as:
X(5+11)
And if there's one variable like 9n+36, than it would be shaped like:
9(n+4)
For word problem 12 you have provided, they give you the base amount of cost when you purchase the ad is (84$) and the cost every day to run it is (28$). The max amount of money we can spend is 700$. With an initial cost of 84$, we can deduct 84$ from the max of 700$, which would leave us with 616$. We can than divide 616$ by 28$ to see how many days we can keep the ad running, which equals 22. So the max amount of days that the ad can be up is 22 days.
For 13, 1 basket is 12 inches tall, and 13.5 inches tall when another one is stacked inside of it. All we have to do here is subtract 12 from 13.5, which gives us 1.5. That means that every basket stacked adds another 1.5 inches. So if you stacked 5 baskets inside of one, it would be 1.5 x 5 + 12.
In 7 for the unit rates, it's just saying that 0.8 of a centimeter grew in four sevenths of a week. It wants to know how many centimeters a week, which would be around 1.4 centimeter per week because 4/5 divided by 4/7 = 7/4 which equals 1.4.
Where you rewrite the expressions to find the least amount of terms, literally all you are doing is combining like terms. on 10 D, you would first distribute 5 and than solve for any like terms (also the parentheses between both equations don't matter because of the sign in between them so you can just remove them). It should be self explanatory to combine like terms so on (like terms includes constants).

Explanation:
To find the answer to this problem, you should go through your list of possible solutions and determine which one will not equal 24 square yards. To determine which one will and will not equal 24, you will have to multiply each solution.
12 • 3 = 36
1 • 24 = 24
4 • 6 = 24
3 • 8 = 24
All but one of our answer is 24, therefore 12yds by 3yds is our answer, because 12 times 3 is 36.
*Side Note*
Considering the part of the question “The area of a rectangular parking lot is 24 square yards.” 1 yard is equivalent to 3 feet, so in retrospect, answer (B) 1 yard by 24 yards, or a 3 foot by 72 foot parking lot would not physically work considering that you typical car is about 5.8 feet wide. No car would be able to fit in that parking lot.
