Jake is wrapping a gift that is in a box with the following dimensions.
Length: 12 inches
Width: 4 inches
Height: 8 inches
Havana is wrapping a gift whose box's dimensions are all twice the length of the lengths in Jake's box.
How many times larger is the surface area of Havana's box than Jake's box?
Enter your answer as a number, like this: 42
HELP PLEASEEEEEEEE
Answer: 8
Step-by-step explanation: first multiply 12x4x8 for jakes gift. that is 384
then make each of the dimensions twice as large. so havanas dimensions would be. 24x8x16
24x8x16=3,072
last divide 3,072 by 384 and the answer would be 8
Havana's box is 8 times larger.
Find the answer and simplify.
What is (4/9)^2?
What is 4 over 9(as a fraction) to the power of 2?
Answer:
16/81
Step-by-step explanation:
To square a fraction, you would have to square both the denominator and the numerator. You would have to do 4x4/9x9, which is 16/81.
Answer:
The answer is 16/81
Step-by-step explanation:
To evaluate this equation first find a understanding of what needs to be solved.
Here we see that we need to solve 4/9th to the power of 2.
to solve this we find what 4 to the power of 2 is and what 9 to the power of 2 is.
To use the power of 2 you multiply the number to itself that many times so if its 5 to the power of 3 you would right it as 5 x 5 x 5.
In this case we need to do 4 x 4 and 9 x 9.
4 x 4 = 16
9 x 9 = 81
The 4 x 4 solution remains as the numerator
The 9 x 9 solution remains as the denominator
After solving we get 16/81, due to the 81 not being even and 16 not being a multiple we can not simplify this fraction anymore.
The correct answer is 16/81 have a great day :)

Ravi had 124 dollars to begin with. He just spent b dollars. Using b , write an expression for the number of dollars he has left.
An expression for the number of dollars he has left is: 124 - B = T
What is an expression?Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
The Numbers constants, variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbol; which can also be used to indicate the logical syntax's order of operations and other features.
We know that Ravi has 124$, we don’t need how much he spent So, for the money he’s spent we are using B to represent it.
The expression is:
124 - B = T
Consider that B is how much money he spent.
T is his total after.

The value of the x is -2 after solving the linear equation by using the elimination method.
What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
It is given that:
The linear equations are:
2x+3y=8
6x−5y=−32
3X(2x+3y=8)
6x + 9y = 24
6x−5y=−32
14y = 56
y = 4
x = -2
Thus, the value of the x is -2 after solving the linear equation by using the elimination method.

By matching the statistical measures with their corresponding values, we have:
Median: 23.5
Mean: 22.5
Mode: 20, 24, 25, 26
Lower Quartile: 21.5
Upper Quartile: 24.5
To match the statistical measures with their corresponding values, we need to analyze the dataset and identify the appropriate measures. Here's the breakdown:
Median: The median is the middle value of the dataset when it is arranged in ascending order. In this case, since we have 12 data points, the middle two values are 23 and 24. Therefore, the median is the average of these two values, which is 23.5.
Mean: The mean is calculated by summing up all the values in the dataset and dividing by the total number of values. Adding up the given values, we get 262. Dividing this sum by 12 (the number of values), we obtain a mean of 22.5.
Mode: The mode represents the value(s) that appear(s) most frequently in the dataset. In this case, the values 20, 24, 25, and 26 all appear twice, making them the modes of the dataset.
Lower Quartile: The lower quartile divides the dataset into four equal parts, with 25% of the data falling below it. To find the lower quartile, we need to locate the value that is greater than or equal to 25% of the data. In this case, the 25th percentile falls between the values 21 and 22. The lower quartile is the average of these two values, which is 21.5.
Upper Quartile: The upper quartile divides the dataset into four equal parts, with 75% of the data falling below it. Similar to the lower quartile, we need to locate the value that is greater than or equal to 75% of the data. In this case, the 75th percentile falls between the values 24 and 25. The upper quartile is the average of these two values, which is 24.5.

Which of the following is equivalent to the expression 2 ( 8y + 1/2 ) Select all that apply.
Answer:
B and C both are equivalent to the expression
Answer:
B, C
Step-by-step explanation:
2(8y+1/2) would be equal to 2x8y+2x1/2=16y+1.
2(8y+1/2) would also be equal to 8y+1/2+8y+1/2 because multiplying by 2 is basically just adding the thing you are multiplying to itself.

9. Andrew was measuring the height of the tree in his yard. Four years after it was planted, the tree was 11 feet tall. Twelve years after the tree was planted, it was 21 feet tall. Assuming the tree was growing at a constant rate, create the equation that models that growth of the tree over time. Show or explain your reasoning. (HINT: Use the two points to find the slope and use point-slope form to create an equation.)
Answer:
y=10/8x+6
Step-by-step explanation:
This is because when you plot the points you can find the slope by using rise over run and by finding the slope you can find the y intercept and that is all you need for the equation.
Answer:
first it show 11ft over 4 years so do 11/4 the answer would be 2.75 ft every year and to try doing it with the tree in 12 years

Does anyone have any ideas for multiplying 249 times 398 quickly and mentally? Everything online is too complex.
Answer:
So, the first solution is a calculator but sometime we don't have a calculator so, do
200 X 300 = A
40 X 90 = B
9 X 8 = C
then add just do multiplication from there like
A + B = D
D + C = E
Then your finally answer would be E
Hope that helps that's the way I do math quick in my head
(Btw the answer to 249 X 398 = 63,672 )
