Answer:
The final answer is 4∛7 cm.
Step-by-step explanation:
Given:
Volume of cube is 448 cm³.
Now, to find the length side(a) of cube.
Putting the formula of volume(v) of cube to get the side:
[tex]V = a^{3}[/tex]
[tex]448= a^{3}[/tex]
[tex]\sqrt[3]{448} = a[/tex]
[tex]4\times 4\times 4\times 7 = a[/tex]
[tex]4\sqrt[3]{7} = a[/tex]
The length side of a cube = 4∛7 cm.
Therefore, the final answer is 4∛7 cm.

When buying groceries at the store for this dinner, you can spend no more than $100. Some costs are fixed, like spices and piecrusts. That total comes to $65. The turkey, however, is priced per pound. The suggestion is that you plan for 1.5 pounds of turkey per guest. If the turkey costs $1.16 per pound, what is the largest size turkey you should buy and how many people can it feed?
Answer:
20 full people
Step-by-step explanation:
100-65=35
35/1.16= 30.1724
30.1724/1.5=20.1149
You can't feed a .1149 of a person so 20 people
Given the maximum budget and cost per pound, the largest turkey you can purchase is approximately 30.17 pounds. This will feed about 20 guests, considering each person consumes 1.5 pounds of turkey.
Explanation:The subject of this question is mathematics, specifically, problem-solving involving budgets and limits. Given that the maximum budget for this dinner is $100 and the fixed costs total to $65, we're left with $35 for the turkey. Each pound of turkey is priced at $1.16.
By dividing the remaining amount of money (which is $35) by the cost per pound of turkey (which is $1.16), we compute the total pounds of turkey we can afford. That is, $35 / $1.16 = approximately 30.17 pounds.
Each guest requires 1.5 pounds of turkey, so we now calculate how many guests can be fed by this amount of turkey. We do this by dividing the total pounds of turkey (30.17 pounds) by the amount required per guest (1.5 pounds), which gives us 30.17 / 1.5 = approximately 20.11. Since you can't invite a fraction of a person, the largest size turkey you can afford can feed about 20 people.

You want it put edging around a rectangular flower garden that is 15 feet long and 12 feet wide. The edging comes in 3 foot pieces. How many pieces of edging do you need to buy
Answer:
18 pieces are needed
Step-by-step explanation:
Edgings are put all around the rectangular flower garden. So we need to know the perimeter (sum of all sides) of the rectangle. The formula is:
Perimeter of Rectangle = 2(Length + Width)
Given,
Length = 15
Width = 12
So,
Perimeter = 2(Length + Width)
Perimeter = 2(15 + 12)
Perimeter = 2(27)
Perimeter = 54
So, we need to cover 54 feet. Each edging is 3 feet in length, so 54 feet will be covered by:
54/3 = 18 edgings

3. A crate with 20 bricks weighs 167 pounds. When the same crate has 32 bricks, it weighs
191 pounds. How much would the crate weigh if there were 19 bricks in the crate?
Explain.
The weight of crate when it has 19 bricks is 165 pounds
Solution:Given that, A crate with 20 bricks weighs 167 pounds.
When the same crate has 32 bricks, it weighs 191 pounds.
Now, let the weight of each brick be "m" pounds and weight of the crate be 'n" pounds.
Then, when crate has 20 bricks
Total weight = weight of bricks + weight of crate
[tex]167 \text { pounds }=\text { number of bricks } \times \text { weight of each brick }+\text { weight of crate }[/tex]
[tex]167=20 \times m+n[/tex]
20m + n = 167 ----- eqn (1)
Now, when crate has 32 bricks
Total weight = weight of bricks + weight of crate
[tex]191 \text { pounds }=\text { number of bricks } \times \text { weight of each brick + weight of crate }[/tex]
[tex]191=32 \times m+n[/tex]
32m + n = 191 ----- eqn (2)
Now, subtract (1) from (2)
32m + n = 191
20m + n = 167
(-) ----------------
12m + 0 = 24
m = 2
Then, from eqn (1)
20(2) + n = 167
40 + n = 167
n = 167 – 40 = 127
Now, when the box has 19 bricks
Total weight = 19 bricks x 2 pounds per brick + 127 pounds of crate
[tex]\text { Total weight }=19 \times 2+127=38+127=165[/tex]
Hence, the weight of crate when it has 19 bricks is 165 pounds.

What is the greatest common factor of 88 and a 121
Answer: 11
Step-by-step explanation: The factors of 88 are 1,2,4,8,11,22,44,88; The factors of 121 are 1,11,121.
Final answer:
To find the greatest common factor (GCF) of 88 and 121, determine the common factors through their prime factorizations, which results in 11 as the GCF.
Explanation:
The greatest common factor (GCF) of 88 and 121 can be found by determining the largest number that can evenly divide both numbers. To find the GCF:
Find the prime factorization of both numbers: 88 = 2 x 2 x 2 x 11 and 121 = 11 x 11.Identify the common factors: In this case, the common factor is 11.Therefore, the greatest common factor of 88 and 121 is 11.50 point for this question:
Find values of a and b that make the following equality into identity:
Answer:
1) The values of 'a' and 'b' are [tex]$ \frac{3}{4} $[/tex] and [tex]$ \frac{3}{4} $[/tex] respectively.
2) The values of 'a' and 'b' are '3' and '-3' respectively.
Step-by-step explanation:
1) Given: [tex]$ \frac{3x}{(x - 2)(3x + 2)} = \frac{a}{x - 2} + \frac{b}{3x + 2} $[/tex]
We solve this by partial fraction method.
Taking LCM in the RHS we get,
[tex]$ \frac{3x}{(x - 2)(3x + 2)} = \frac{a(3x + 2) + b(x - 2)}{(x - 2)(3x + 2)} $[/tex]
[tex]$ \implies 3x = a(3x + 2) + b(x - 2) $[/tex]
To find the value of 'a', substitute x = 2. This would make 'b' vanish leaving an equation with 'a'.
[tex]$ \therefore 3(2) = a(3.2 + 2) + b (2 - 2) \implies 6 = a(8) $[/tex]
[tex]$ \implies a = \frac{-2}{3} $[/tex]
Now, Substitute [tex]$ x = \frac{-2}{3} $[/tex] to solve for 'b'.
[tex]$ \implies 3(\frac{-2}{3}) = a (3.\frac{-2}{3} + 2) + b(\frac{-2}{3} -2) $[/tex]
[tex]$ \implies -2 = b \frac{-8}{3} $[/tex]
[tex]$ \implies b = \frac{3}{4} $[/tex]
Therefore, a = [tex]$ \frac{3}{4} $[/tex] and b = [tex]$ \frac{3}{4} $[/tex]
2) Given [tex]$ \frac{3}{x^2 - 5x + 6} = \frac{a}{x - 2} + \frac{b}{x - 3} $[/tex]
We follow the same procedure as (1).
Taking LCM we get
[tex]$ \frac{3}{x^2 - 5x + 6} = \frac{a (x - 3) + b(x - 2)}{(x^2 - 5x + 6)} $[/tex]
[tex]$ \implies 3 = a(x - 3) + b(x - 2) $[/tex]
Substituting x = 2, we get:
3 = a(-1) [tex]$ \implies a = -3 $[/tex]
Also, Substituting x = 3, we get:
3 = b(1)
[tex]$ \implies b = 1 $[/tex]
Therefore, the values of a and b are -1 and 1 respectively.
This scale drawing of a rectangular wall has dimensions 4.75 inches by 2.5 inches. The length of the shorter side of the actual wall is 36 inches.
Enter the area of the actual wall.
I will mark the first one who answers me brainleist
_[blank]_ square inches
Answer:
2462.4 square inches
Step-by-step explanation:
To find the length of the longer wall use the following ratio and solve for x.
x/36= 4.75/ 2.5
x= 68.4
Area of a rectangle = l(w)
68.4(36)= 2462.4 square inches
The area of the wall is the product of its dimension.
The area of the actual wall is 2462.4 square inches
The scale is given as:
[tex]\mathbf{Scale = 4.75 : 2.5}[/tex]
The shorter side of the actual wall is 36 inches.
So, we have:
[tex]\mathbf{Long : 36= 4.75 : 2.5}[/tex]
Express as fractions:
[tex]\mathbf{\frac{Long }{36}= \frac{4.75 }{ 2.5}}[/tex]
Multiply both sides by 36
[tex]\mathbf{Long= 36 \times \frac{4.75 }{ 2.5}}[/tex]
[tex]\mathbf{Long= 68.4}[/tex]
So, we have:
[tex]\mathbf{Long= 68.4}[/tex]
[tex]\mathbf{Short= 36}[/tex]
The area is then calculated as:
[tex]\mathbf{Area = 68.4 \times 36}[/tex]
[tex]\mathbf{Area = 2462.4in^2}[/tex]
Hence, the area of the actual wall is 2462.4 square inches

Mitch paid $ 33600 altogether
Solution:Given that mitch took out a school laon for $ 24000
The interest rate on the loan was 8%
Number of years = 5
To find: total amount paid altogether
We can use simple interest to calculate the total amount
Total amount paid altogether = simple interest + principal amount
The simple interest is calculated as:
[tex]\text { simple interest }=\frac{\text { principal } \times \text {rate of interest } \times \text {number of years}}{100}[/tex]
Plugging in values, we get
[tex]\text { simple interest }=\frac{24000 \times 8 \times 5}{100}=240 \times 8 \times 5=9600[/tex]
Total amount paid altogether = simple interest + principal amount
Total amount paid altogether = 9600 + 24000 = 33600
Thus Mitch paid $ 33600 altogether
A card is randomly selected from a standard deck of 52 playing cards. What is the probability that it is a face card or a spade?
Answer:
8/13.
There's 12 face cards & 26 black cards. In the 26 black cards, theres 6 face cards. Theres 32 cards overall that is either a black card or a face card. So in conclusion the answer is 8/13 because 52 (the total amt in the deck) divided by 32 = 8/13.
The probability of randomly selecting either a face card or a spade from a standard deck of 52 playing cards is approximately 0.4231.
The question involves calculating the probability of selecting either a face card or a spade from a standard deck of 52 playing cards. A standard deck consists of four suits (spades, hearts, diamonds, clubs), each with 13 cards, making a total of 52 cards. Among these, 12 are face cards (Jacks, Queens, Kings across all suits), and 13 are spades (including the spade face cards).
First, note that there are 3 face cards (Jack, Queen, King) in each suit, resulting in 12 face cards in total. However, 3 of these face cards are spades, and we must avoid double-counting them when adding the spade cards. Therefore, we have 12 face cards and 10 non-face card spades (since 3 spades are already counted among face cards), giving us a total of 22 unique cards that fulfill the conditions.
The probability of drawing either a spade or a face card from a deck of 52 cards is calculated by dividing the number of favorable outcomes (22) by the total number of outcomes (52), which is 22/52 or approximately 0.4231.

A 36 foot long roll of banner material must be cut into three pieces with no material left over to make three banners. The second banner must be 4 feet longer than the first banner in the third banner must be also 4 feet longer than the second. How long should each banner be
Answer:
The length of the first banner = 8 ft
The length of the second banner = 12 ft
The length of the third banner = 16 ft
Step-by-step explanation:
The total length of the banner material = 36 ft
Now, let us assume the length of the first banner = k ft
So, the length of the second banner = First banner + 4 ft = ( k + 4) ft
The length of the third banner = Second banner + 4 ft = [( k + 4) + 4] ft
Now, according to the question:
The length of ( First + Second + Third) banner = 36 ft
⇒ (k) + (k +4) + (k + 8) = 36
or, 3 k = 36 - 12= 24
or, k = 24/3 = 8
⇒ k = 8 ft
So, the length of the first banner = k = 8 ft
The length of the second banner = k + 4 = 8 + 4 = 12 ft
The length of the third banner = k + 4 + 4 = 8 + 8 = 16 ft

In a video game, Conner scored 25% more points than Max. If c is the number of points that Conner scored and m is the number of points that Max scored, which equations are correct?
Select all that apply
A. c - m + 0.25
B. c = (1 + 0.25)m
C. c = 1.25m
D. c = m + 0.25m
E. c = m + 25
Please explain to me why the correct answers is B, C and D. What kind of math problem is this as well?
The correct choices B, C, and D all represent the equation that Conner scored 25% more points than Max, using algebraic terms to demonstrate this proportional increase. Choices B and C show the total score as a multiple of Max's score, while D adds an extra 25% to Max's score.
Explanation:The problem presented is an algebraic representation of a proportional relationship. Given that Conner scored 25% more points than Max, we can express this relationship in different but equivalent equations. Choices B, C, and D effectively communicate that Conner's score, c, is increased by 25% more than Max's score, m.
Choice B is written as c = (1 + 0.25)m, which represents a 100% (which is 1 in decimal form) of Max's score plus an additional 25%. Choice C simplifies this to c = 1.25m, which is another way to represent a 25% increase on Max's score. Choice D is expressed as c = m + 0.25m which sums Max's score with another 25% of it. Each of these equations correctly translates the scenario into a mathematical expression.

1. Use the formula S(d)=√9.8d to calculate the estimated speed, in meters per second, of a tsunami if the disturbance occurred at an ocean depth of 4,500 meters.
2. Convert the answer from question one from meters per second to kilometers per hour. (Hint: A meter per second is equal to 3.6 kilometers per hour.)
Answer: 1. 210 meters per second .
2. 756 kilometers per hour.
Step-by-step explanation:
Given : The formula [tex]S(d)=\sqrt{9.8d}[/tex] to calculate the estimated speed, in meters per second of a tsunami.
1. If the disturbance occurred at an ocean depth of 4,500 meters.
Then put d= 4500 in the above formula , we get
[tex]S(d)=\sqrt{9.8\times4500}[/tex]
[tex]S(d)=\sqrt{44100}=\sqrt{21\times21\times10\times10}\\\\=\sqrt{210^2}=210[/tex]
Hence, if the disturbance occurred at an ocean depth of 4,500 meters , the estimated speed would be 210 meters per second .
Also, A meter per second is equal to 3.6 kilometers per hour.
i.e. 1 meter per second = 3.6 kilometers per hour
Then by unitary method ,
210 meters per second =[tex]3.6\times210[/tex] kilometers per hour
=756 kilometers per hour.
