\(\sqrt[3]{488+24} \\\)
Answer:
8
Step-by-step explanation:
First, add the values inside the radical
488+24 = 512
\(\sqrt[3]{512}\) = x
This means that: \(x^{3}\) = 512
Therefore, x must be equal to 8.
\(\sqrt[3]{512}\) = 8
56.7+23.44 useing front-end to estimate the sum
Answer:
Step-by-step explanation:
To estimate the sum of 56.7 and 23.44 using the front-end method, you can round each number to the nearest whole number and then add them together. This will give you an estimate of the sum that is close to the actual result.
Using this method, you would round 56.7 to 57 and 23.44 to 23, and then add them together to get an estimate of 80. This is a reasonable estimate of the sum of 56.7 and 23.44, which is actually 80.14.
Note that this method is not as accurate as using a calculator or performing the exact calculation, but it can be a useful tool for quickly estimating the sum of two numbers.
Answer:80
Step-by-step explanation: 56.7 when rounded is 57 and 23.44 rounded is 23 so 57+23 is 80

The box plot shows the number of jumping jacks completed in a workout class by the class members. A box plot uses a number line from 14 to 54, with tick marks every one unit. The box extends from 26 to 49 on the number line. A line in the box is at 40. The lines outside the box end at 15 and 52. The graph is Jumping Jacks Completed, and the line is labeled Number of Jumping Jacks. Which of the following lists the range and IQR for this data? The range is 23, and the IQR is 37. The range is 40, and the IQR is 37. The range is 40, and the IQR is 23. The range is 37, and the IQR is 23.
Answer:
The range is 37, and the IQR is 23.
Step-by-step explanation:
A box plot (also known as a "box and whisker plot"), is a graph displaying the distribution of a set of data based on a five-number summary.
Five-number summaryMinimum value is at the end of the left whisker.Lower quartile (Q₁) is the left side of the box.Median (Q₂) is the vertical line inside the box.Upper quartile (Q₃) is the right side of the boxMaximum value is at the end of the right whisker.From the given information, the five-number summary of the Jumping Jacks box plot is:
Minimum = 15Lower quartile (Q₁) = 26Median (Q₂) = 40Upper quartile (Q₃) = 49Maximum = 52RangeThe range is the difference between the maximum and minimum values. Therefore, the range for the data is:
\(\sf Range = 52 - 15 = \boxed{\sf 37}\)
Interquartile range (IQR)The IQR is the difference between the upper quartile and the lower quartile. Therefore, the IQR for the data is:
\(\sf IQR = Q_3 - Q_1 = 49 - 26 = \boxed{\sf 23}\)
SummaryThe range is 37, and the IQR is 23.
Use a number line to order the numbers from least to greatest.
Assign the numbers to the number line in the following order:
2.15=2.15
220%=2.2
9/4=2.25
*2.15* is easy enough to place as it is already in decimal form. However, the other 2 options need to be converted to decimals in order to be placed. We have the fraction 9/4 and percentage 220%. 9/4 can either be simply divided on a calculator or turned into the mixed fraction 2 and 1/4, which is *2.25*. Finally, we know that converting a decimal to a percentage we multiply the decimal by 100. Therefore, to convert a percentage to a decimal we divide 100 or move the decimal to the left 2 places. With this conversion rule, 220% transforms to *2.2* and we have the third and final number for our number line. Arranging these three numbers from least to greatest:
2.15, 2.2, 2.25

Considering area (A) of garden as 30 square feet:
30 = x(2x+7)
Now we need to expand it:
x(2x+7) = 2x^2 + 7x
2x^2 + 7x = 30
Adding this into an Algebra calculator gives us 5/2 or 2.5
So x = 2.5
To prove this:
2(2.5) + 7 = 12
14 * 2.5 = 30
A math team is working through a set of puzzles. The following diagram describes the numbers of puzzles they've started and not yet started.
Answer:2:5
Step-by-step explanation: We can count the equal parts in the diagram to find the ratio of puzzles started to total puzzles, but that ratio is not one of the choices.
To make an equivalent ratio, we multiply both values in the first ratio by the same number. We can also divide both values by the same number.
Identifying the given ratio
6 + 9 = 15
There are 6 puzzles started for every 15 total puzzles.
The answer choices use smaller numbers. Let's create an equivalent ratio by dividing 6 and 15 by the same number.
Creating an equivalent ratio
We can divide 6 and 15 by 3 to get 2 and 5
Yes, the ratio 2:5 is equivalent to 6:15!
The ratio of puzzles started to total puzzles answers is 2:5.

which expression can be used to find the surface area of the following square pyramid
Answer:
a. 36+15+15+15+15
Step-by-step explanation:
The base of the pyramid is a square. We know that all sides of a square are equal so if we multiply the two sides of the base square(6*6) we get 36.
The area of a triangle can be found with the formula (b*h)/2. If we input the given values of 5 and 6 into our equation, then (5*6)/2 is 15 and since there are 4 triangles in the square pyramid, you multiply 15 by 4 (or add 15+15+15+15), and add the 36 from the base square.
Hope this helps :)
