a box of powdered sugar has the dimensions shown below
The rule of the surface area of a box whose dimensions are L, W, and H is
\(S.A=2(L\times W+L\times H+W\times H)\)Since the dimensions of the sugar box are 10 cm, 5 cm ,and 16 cm, then
L = 10
W = 5
H = 16
Substitute them in the rule above
\(\begin{gathered} S.A=2(10\times5+10\times16+5\times16) \\ \\ S.A=2(50+160+80) \\ \\ S.A=2(290) \\ \\ S.A=580\text{ cm}^2 \end{gathered}\)The surface area is 580 square cm
You are given that a = 6.54 (to 3 significant figures) and b = 123 (to 3 significant figures).

(a) a + b
(b) ab
(c) a/b
(d) b - 1/a
The upper and lower bounds for the numbers are illustrations of approximation
How to calculate the upper and lower boundsThe numbers are given as:
a = 6.54 (to 3 significant figures)
b = 123 (to 3 significant figures)
(a) a + b
We have:
a + b = 6.54 + 123
a + b = 129.54
When approximated, the bounds to three significant digits are:
Lower bound = 129
Upper bound = 130.1
(b) ab
We have:
ab = 6.54 * 123
a + b = 804.42
When approximated, the bounds to three significant digits are:
Lower bound = 804
Upper bound = 805
(c) a/b
We have:
a/b = 6.54/123
a/b = 0.0531707317
When approximated, the bounds to three significant digits are:
Lower bound = 0.0531
Upper bound = 0.0532
(d) b - 1/a
We have:
b - 1/a = 123 - 1/6.54
b - 1/a = 122.847094801

A rectangle has a length 2m less than twice its width. When 2m are added to the width, the resulting figure is a square with an area of 36m^2. Find the dimensions of the original rectangle
Answer:
width: 4 mlength: 6 mStep-by-step explanation:
You want the dimensions of a rectangle if adding 2 m to its width makes it a square with an area of 36 m².
Square dimensionsThe area of a square is the square of its side length, so the side length of the square is ...
A = s²
s = √A = √(36 m²) = 6 m
RectangleThe problem statement tells you this dimension is 2 m more than the width of the rectangle. Hence that width is ...
6 m - 2m = 4 m
The rectangle is 4 m wide and 6 m long.
Check
The length is 2 m less than twice the width: (2)(4 m) -2 m = 6 m, the value we show above.

Ken bought a car last year to drive back and forth to work. Last year he spent $1,098 on gas. This year, it was $1,562. What is the inflation rate?
The inflation rate for Ken's gas expenses between the two years is approximately 42.26%.
To calculate the inflation rate for Ken's gas expenses, we can use the following formula: (Current Year Expense - Previous Year Expense) / Previous Year Expense × 100%.
In this case, the previous year's gas expense was $1,098 and the current year's expense is $1,562.
To find the difference in expenses, subtract the previous year's expense from the current year's expense: $1,562 - $1,098 = $464.
Now, divide this difference by the previous year's expense: $464 / $1,098 ≈ 0.4226.
Finally, multiply the result by 100% to get the inflation rate: 0.4226 × 100% ≈ 42.26%.

6. If n (E) = 40, n (A) = 22, n (ANB) = 8 and n ((AUB)') = 6, determine n(B)
Answer:
4
Step-by-step explanation:
First n(AUB)=n(E) - n((AUB)')
So n(AUB) = 40 - 6 = 34
Now all u hv to do is use the formulae,
n(AUB) = n(A) + n(B) - n(ANB)
So when u substitute above values,
34=22 + n(B) - 8
So,
n(B) = 4

Find the center, foci, and vertices of the hyperbola, and sketch its graph using asymptotes as an aid.
y^2 − 16x^2 + 64x − 208 = 0
The center of the hyperbola is at (2,0), and its vertices are at (2 ± √17,0). The distance between the center and vertices is 'a', which is √17.
The given equation is in the standard form of a hyperbola, which is (y - k)2/a2 - (x - h)2/b2 = 1.
Where (h, k) is the center of the hyperbola, 'a' is the distance from the center to the vertices, and 'b' is the distance from the center to the co-vertices.
To find the center, foci, and vertices of the hyperbola, we need to convert the given equation into the standard form.
First, we need to complete the square for x terms by taking -16 common from x terms and adding and subtracting 16 from it.
y^2 - 16x^2 + 64x - 208 = 0
y^2 - 16(x^2 - 4x) = 208
y^2 - 16(x^2 - 4x + 4) = 208 + 16(4)
y^2 - 16(x - 2)^2 = 272
Now we can write this equation in standard form by dividing both sides by 272.
(y - 0)2/16 - (x - 2)2/17 = 1
Comparing this equation with the standard form, we get:
- Center(h,k) = (2,0)
- a = √17
- b = 4
Therefore, the center of the hyperbola is at (2,0), and its vertices are at (2 ± √17,0). The distance between the center and vertices is 'a', which is √17. The co-vertices are at (2, ±4), and the distance between the center and co-vertices is 'b', which is 4.
To find the foci of the hyperbola, we can use the formula:
c = √(a^2 + b^2)
Where 'c' is the distance between the center and foci.
Substituting the values of 'a' and 'b', we get:
c = √(17 + 16) = √33
Therefore, the foci of the hyperbola are at (2 ± √33,0).
To sketch the graph of the hyperbola, we can use the information we have obtained so far.
The center of the hyperbola is at (2,0), which is the point where the two axes intersect. The vertices are at (2 ± √17,0), which are on either side of the center along the x-axis. The co-vertices are at (2, ±4), which are on either side of the center along the y-axis.
The asymptotes of a hyperbola pass through its center and have slopes equal to ±(b/a). Therefore, for this hyperbola, the slopes of asymptotes are ±(4/√17).
The lines represent the asymptotes passing through the center (2,0) with slopes ±(4/√17). The points represent the vertices at (2 ± √17,0), and the green points represent the foci at (2 ± √33,0).

For every person who actually has the flu, there are 6 people who have flu-like symptoms resulting from a cold. If a doctor sees 40 patients, write and solve a proportion to determine how many of these you would expect to have a cold
Answer: The number of people can be expected to have cold = 34
Step-by-step explanation:
Given: The ratio of people who actually have the flu to the people who have flu-like symptoms is 1:6.
If a doctor sees 40 patients, then the number of people can be expected to have cold = \(40\times\dfrac{6}{1+6}\)
\(=40\times\dfrac6{7}\)
\(=\dfrac{240}{7}\\\\=34.29\approx34\)
Hence, the number of people can be expected to have cold = 34

Scientists were interested in testing a new technique to prevent slipping on ice: wearing socks over boots!
500
500500 volunteers were randomly assigned to two groups. Both groups were asked to walk downhill on an icy road. One group simply wore boots, while the other group wore socks over their boots. All boots and socks were supplied by the scientists.
Once downhill, the participants were asked to indicate the number of times they slipped. Then, the scientists compared the average "slipperiness" score of each group.
What type of statistical study did the scientists use?
Answer:
The scientist used the experimental statistical study.
Step-by-step explanation:
Statistical study is the process of collecting, analyzing and presentation of data to achieve an accurate conclusion. The major types are: survey, and experimental.
Survey statistical study can easily be achieved by the use of questionnaires to sample the opinion of participants. While experimental statistical study involve the participants observing a process or some procedures before conclusions can be made.
In the given question, the scientist performed an experiment by asking participant to undergo a process before making his conclusion. Thus, he used an experimental statistical study.

FILL IN THE BLANK. the sequence of 3 bases on mrna is a and the sequence of 3 bases on trna is . group of answer choices
The sequence of 3 bases on mRNA is called a codon, and the sequence of 3 bases on tRNA is called an anticodon.
Explanation: In the process of protein synthesis, mRNA (messenger RNA) carries the genetic information from DNA to the ribosomes. The mRNA sequence is composed of a series of codons, each consisting of three nucleotide bases (A, U, G, or C). Each codon codes for a specific amino acid or serves as a start or stop signal.
On the other hand, tRNA (transfer RNA) is responsible for carrying the corresponding amino acids to the ribosomes during protein synthesis. Each tRNA molecule contains an anticodon, which is a sequence of three nucleotide bases that is complementary to a specific codon on mRNA. The anticodon allows tRNA to recognize and bind to the appropriate codon on mRNA, ensuring the correct amino acid is added to the growing polypeptide chain.
Therefore, the codon on mRNA and the anticodon on tRNA pair up during translation to facilitate the accurate translation of genetic information into protein sequences.
