Answer:
135
Step-by-step explanation:
The little cubes with side length 1/3 unit have volume (1/3 unit)³ or (1/27 unit)³. Divide the prism volume (5 units³) by (1/27 units³) to determine how many little cubes are required to fill the prism:
5 units³
--------------- = 135 little cubes.
1/27 unit
Note: This assumes that the dimensions of the prism are such that there is no wasted space when all these little cubes are packed inside. For example, if the width of the prism were 3, then we assume that 3 little cubes would fit that particular dimension.
There are 135 cubes in the cube with a volume of 5 cubic units and the small cube has a side length of 1/3 unit.
What is a cube?It is defined as three-dimensional geometry that has six square faces and eight vertices.
As we know, the volume of the cube = side³
The volume of the rectangular prism = 5 cubic units
The volume of the small cube with side lengths of 1/3 unit is:
= (1/3)×(1/3)×(1/3)
= 1/27
The number of cubes in the big cube = 5/(1/27)
= 5×27
= 135 cubes
Thus, there are 135 cubes in the cube with a volume of 5 cubic units and the small cube has a side length of 1/3 unit.

Anna and Tamara have four suitcases. Anna's suitcases' weights are represented by x + 4 and 4x - 5. Tamara's suitcases' weights are represented by -3x + 2 and 2x + 4. Write an algebraic expression that represents the total weight of all the suitcases.
Answer:
4x + 5
Step-by-step explanation:
x + 4 + 4x - 5 - 3x + 2 + 2x + 4
= 4x + 5
The algebraic expression that represents the total weight of all the suitcases (Anna's and Tamara's) is 6x + 5.
To find the total weight of all the suitcases, we need to add the weights of Anna's four suitcases and Tamara's four suitcases.
Anna's suitcases' weights: x + 4 and 4x - 5
Tamara's suitcases' weights: -3x + 2 and 2x + 4
The total weight can be represented by the algebraic expression:
Total weight = (x + 4) + (4x - 5) + (-3x + 2) + (2x + 4)
Now, let's simplify the expression:
Total weight = x + 4x - 3x + 2x + 4 - 5 + 2 + 4
Total weight = 6x + 5
So, the algebraic expression that represents the total weight of all the suitcases is 6x + 5.

What three digit number would need no ungrouping to subtract from?
Answer:
999
Step-by-step explanation:
Regrouping used to be called borrowing. Since no single column can have a digit larger than 9, then you would have the number 999 where you would never have to "borrow", or "regroup
Final answer:
A three-digit number that requires no ungrouping for subtraction should have each digit greater than the corresponding digit in the number being subtracted. For example, subtracting 234 from 453 requires no ungrouping because each digit in 453 is greater than the corresponding digit in 234.
Explanation:
The student's question pertains to the process of subtraction without requiring ungrouping, also known as regrouping or borrowing, when subtracting from a three-digit number. To avoid ungrouping, the number we subtract from should have each digit larger than the corresponding digit of the number being subtracted. For simplicity, let's consider subtracting a three-digit number of the form XYZ, where X, Y, and Z are individual digits. To ensure there's no need for ungrouping, the number from which we are subtracting should have each place value (hundreds, tens, and ones) greater than or equal to those in XYZ.
For example, if we take the number 453 and subtract 234 from it, no ungrouping is needed because 4 is greater than 2, 5 is greater than 3, and 3 is greater than 4. Hence, any three-digit number with digits greater than those of the subtrahend in the corresponding place values would satisfy the condition of needing no ungrouping to subtract from. By following this rule, the process of subtraction becomes straightforward without the complication of borrowing across place values.
How would adding a score of 0 to this data affect the mean and median game scores - i ready lesson ......Choice of measures of center or variability
Answer:
I need to know the data to answer the question
Step-by-step explanation:
Adding a score of 0 to your data will lower both the mean and median, and could potentially increase the standard deviation and affect the percentile rankings.
Explanation:Adding a score of 0 to your data set will affect both the mean (average) and the median (middle value) of the scores. Thus, adding a zero will decrease the mean. The median is the middle score when all the scores are arranged in order. If you add a score that is lower than the current median score, the median will either stay the same or decrease, depending on the number of scores. If the number of scores is odd, the median will remain the same, if the number is even, the median will decrease.
The standard deviation is a measure of the variability or dispersion of a set of scores. If all values are the same, the standard deviation is zero. The standard deviation is small when the scores are close to the mean and larger when the scores vary more from the mean. Adding a score of zero could increase the standard deviation, depending on the other scores.
The percentiles in your data represent the value below which a given percent of data falls. Adding a score of 0 could potentially affect the percentile rankings of the other scores.

Identify the equation of the circle B with center B(4,−6) and radius 7. HELP ASAP!!
Answer:
(x − 4)2 + ( y + 6)2 = 49
Step-by-step explanation:
The equation of a circle with center (h, k) and radius r is (x − h)2 + (y − k)2 = r2.
Define h, k and r using the given values. So, h = 4, k = −6 and r = 7.
Substitute the values into the equation of a circle:
(x − 4)2 + (y − (−6))2 =72

D the distance above sea level after increasing 24 m after depth of 24 m below sea level.
Answer:
It's D.
Step-by-step explanation:
That would be D.
-24 + 24 = 0.
Answer:
The correct option is D) The distance above sea level after increasing 24 m after depth of 24 m below sea level.
Step-by-step explanation:
Consider the provided information.
We need to find Which situation results in the final value of zero.
Option A) E the temperature after a decrease of 5°F from a temperature of -5°F.
Decreasing means we need to subtract 5°F from the existing temperature.
E=-5°F-5°F=-10°F
Hence, now the temperature is -10°F.
Therefore, it is not the correct option.
Option B) The height of an airplane after taking off from ground level and rising 1000 feet.
If the airplane was at the ground level then we consider the height of the airplane was 0 feet above the ground.
After taking off it is rising 1000 feet above the ground level that means the overall rising is 1000 feet.
Therefore, it is not the correct option. As final value is not 0.
Option C) See the amount of money received and change after making a $10 purchase with the $20 bill.
If you purchase something which cost you $10 and you are purchasing it with the $20 bill.
The money you will received is: $20-$10=$10
Which is not 0.
Therefore, it is not the correct option.
Option D) The distance above sea level after increasing 24 m after depth of 24 m below sea level.
The previous position of the object was 24 m below sea level
It can be written as -24m as the distance is below sea level.
Now the object Increasing 24 m, therefore,
-24+24=0
Hence, the final value is zero.
Therefore, the correct option is D) The distance above sea level after increasing 24 m after depth of 24 m below sea level.

Your gross pay is $2,759.00. Your involuntary deductions are FICA (7.65%), federal withholding (12%), and state withholding (7%). How much are you allowed for housing and fixed expenses?
After calculating the total involuntary deductions for FICA, Federal withholding, and State withholding, we subtract this total from the gross pay to determine the amount available for housing and fixed expenses, which is $2023.63.
Explanation:To find out how much you are allowed for housing and fixed expenses, we first need to calculate the total involuntary deductions. This is done by applying the given percentages to the gross pay.
For the FICA it would be: $2759.00 * 7.65% = $211.16
Federal withholding would be: $2759.00 * 12% = $331.08
And for the State withholding: $2759.00 * 7% = $193.13
You'll then add all the deductions together: $211.16 + $331.08 + $193.13 = $735.37
The final step is to subtract the total deductions from the gross pay: $2759.00 - $735.37 = $2023.63
Hence, you are allowed $2023.63 for housing and fixed expenses.

ANSWER
[tex]y = \frac{1}{3} \cos(x) - 2[/tex]
EXPLANATION
If the graph of y=cosx is transformed to y=a cos (x−c)+d by a vertical compression by a factor of 1/3 and a translation 2 units down,
then
a=1/3
and d=-2.
The 'c' is a phase shift since it is not given, it means it is zero.
Therefore the new equation is:
y=1/3cos(x-0)−2
This simplifies to:
y=1/3cosx−2
The correct option is C.
Answer:
The new equation is y = 1/3 cos(x) - 2 ⇒ 3rd answer
Step-by-step explanation:
* Lets revise the trigonometry transformation
- If the equation is y = a cos(x - c) + d
# a is the scale factor of a vertical stretch or compression
# c is the phase shift (negative is to the right, positive is to the left)
# d is the vertical shift
- If y = cos(x)
∴ a = 1 , c = 0 , d = 0
* Now lets solve the problem
∵ There is a vertical compression by a factor of 1/3
∴ a = 1/3
∵ There is a translation 2 units down (vertical translation)
∴ d = -2
∵ There is now phase shift (horizontal translation)
∴ c = 0
* Now lets write the new equation
∴ y = 1/3 cos(x) - 2
* For more understand look to the attached color graph
- The red is y = cos(x)
- The blue is y = 1/3 cos(x) - 2

From any point (x, y) on the parabola the focus and directrix are equidistant.
Using the distance formula
[tex]\sqrt{(x-4)^2+(y-1)^2}[/tex] = | y - 5 |
Squaring both sides
(x - 4)² + (y - 1)² = (y - 5)² ← distribute the factors in y
(x - 4)² + y² - 2y + 1 = y² - 10y + 25 ( subtract y² - 10y + 25 from both sides )
(x - 4)² + 8y - 24 = 0 ( subtract (x - 4)² from both sides )
8y - 24 = - (x - 4)² ← add 24 to both sides )
8y = - (x - 4)² + 24 ( divide both sides by 8 )
y = - [tex]\frac{1}{8}[/tex] (x - 4)² + 3
Hence
f(x) = - [tex]\frac{1}{8}[/tex] (x - 4)² + 3 → C
Jan typically earns $575 per week. She has $172.50 withheld from her paycheck each week. What percent is being withheld from her paycheck? Type your answer as a percentage using the % symbol.
Answer:
30%
Step-by-step explanation:
What your problem is asking basically is how many percent is the withholding of her earnings each week. We just divide what is withheld by the earnings.
[tex]\dfrac{172.50}{575}=0.3[/tex]
Because we need it in percentage, we then multiply it by 100%.
0.30 x 100% = 30%
Answer:
30%

The length of a rectangle is 6 1/2 inches and the width is 3 3/4 inches. What is the ratio, using whole numbers, of the length to the width?
Answer:The length is 13/2, while the width is 15/4, after combination. Ratio of length to width is then (13/2)/(15/4) = 26/15.
Which of the following is an infinite series?
A. 4 + 8 + 16 + 32
B. 2 − 6 + 18 − 54 + . . .
C. 3, 13, 23, 33, . . .
D. 3, –6, 12, –24, 48
Given the recursive formula below, what are the first 4 terms of the sequence?
A. 17, –6, –3, 0
B. 17, 22, 39, 56
C. 17, 39, 105, 303
D. 17, 63, 201, 615
Answer:
for the first question it would be A. 4+8+16+32 because infinite series are such as :
9,18,36,72,144,288
10,20,40,80,160,
so basically its multiplying *2
