Which multiplication equation is related to the division equation 1/9 ÷ 5 = __
A. 5 x 1/25=1/9
B. 1/45 x 5=1/9
C. 1/45 x 1/5=1/9
D. 5 x 1/15=1/9
Answers
Answer: B. \(\dfrac1{45}\times5=\dfrac19\)
Step-by-step explanation:
We know that,
\(\dfrac{a}{b}\div\dfrac{c}{d}=\dfrac{a}{b}\times\dfrac{d}{c}\)
Then, \(\dfrac19\div 5\) \(=\dfrac19\times\dfrac15\)
\(=\dfrac1{45}\)
i.e.
\(\dfrac19\div 5=\dfrac{1}{45}\\\\\Rightarrow\ \dfrac1{45}\times5=\dfrac19 \ \ \ \text{[Multiply 5 on both sides]}\)
Therefore, the multiplication equation is related to the division equation \(\dfrac1{45}\times5=\dfrac19\)
Hence, the correct option is B. \(\dfrac1{45}\times5=\dfrac19\)

7 The time in minutes (7) taken to cook a joint of beef is given by T-35w +25,
where w is the weight of the joint in kg.
a) How long would it take to cook a 1.5 kg joint?
b) Make w the subject of the formula.
c) What weight of beef needs to be cooked for 207 minutes?
d) What weight of beef needs to be cooked for 3 hours and 48 minutes?
1:11
Answers
In conclusion for part A it would take T - 32.5 minutes to cook a 1.5 kg joint. For part B w is given by the formula w = (T - 25) / (-35). For part C 6.6 kg of beef needs to be cooked for 207 minutes. For part D 5.91 kg of beef needs to be cooked for 3 hours and 48 minutes.
How to solve?
a) To find how long it would take to cook a 1.5 kg joint, we can substitute w = 1.5 into the formula:
T - 35w + 25 = T - 35(1.5) + 25 = T - 32.5
So, it would take T - 32.5 minutes to cook a 1.5 kg joint.
b) To make w the subject of the formula, we need to isolate w on one side of the equation. We can start by subtracting 25 from both sides:
T - 35w = T - 25
Next, we can divide both sides by -35:
w = (T - 25) / (-35)
Therefore, w is given by the formula w = (T - 25) / (-35).
c) To find the weight of beef that needs to be cooked for 207 minutes, we can substitute T = 207 into the original formula:
T - 35w + 25 = 207
Simplifying this equation, we get:
-35w = -232
Dividing both sides by -35, we get:
w = 6.6 kg
Therefore, 6.6 kg of beef needs to be cooked for 207 minutes.
d) To find the weight of beef that needs to be cooked for 3 hours and 48 minutes (which is equivalent to 3 × 60 + 48 = 228 minutes), we can substitute T = 228 into the original formula:
T - 35w + 25 = 228
Simplifying this equation, we get:
-35w = -207
Dividing both sides by -35, we get:
w = 5.91 kg
Therefore, 5.91 kg of beef needs to be cooked for 3 hours and 48 minutes.

The probability that a person cannot read is 0.85 what is the probability that 2 people selected at random will be unable to read
Answers
Answer: 0.7225
Step-by-step explanation:
Since the probability that a person cannot read is 0.85. The probability that 2 people selected at random will be unable to read will be gotten by multiplying the value of the probability given twice. This will be
= P(not read) × P(not read)
= 0.85 × 0.85

Therefore, the probability that 2 people selected at random will be unable to read is 0.7225
iven a Cobb Douglas production function, \( q=L^{0.45} K^{0.55} \), determine the Marginal Rate of Technical ubstitution.
Answers
Therefore, the Marginal Rate of Technical Substitution (MRTS) in this Cobb Douglas production function is (0.45/0.55) * (L/K), or approximately 0.818 * (L/K).
To determine the Marginal Rate of Technical Substitution (MRTS) in a Cobb Douglas production function, we need to calculate the ratio of the marginal product of labor (MP_L) to the marginal product of capital (MP_K). In this case, the MRTS can be calculated as MRTS = MP_L / MP_K, where MP_L is the partial derivative of the production function with respect to labor (L) and MP_K is the partial derivative of the production function with respect to capital (K).
Taking the partial derivatives of the Cobb Douglas production function, we have:
MP_L = 0.45 * L^(-0.55) * K^0.55
MP_K = 0.55 * L^0.45 * K^(-0.45)
Now we can calculate the MRTS:
MRTS = MP_L / MP_K
= (0.45 * L^(-0.55) * K^0.55) / (0.55 * L^0.45 * K^(-0.45))
= 0.45/0.55 * (L^(-0.55) * L^0.45) * (K^0.55 * K^(-0.45))
= (0.45/0.55) * (L/K)

At how many values of a(0° < a < 360°) does pentagon A'B'C'DE' coincide with pentagon ABCDE? What is significant about this
number?
Answers
Answer: each time the pentagon is rotated 72, it maps back onto itself. There are five values of a for which the pentagon maps back onto itself. this is the same as the number of sides of the pentagon.
Step-by-step explanation: edmentum
A regular pentagon has 5 congruent sides and a measure of 360 degrees, at its center.
Pentagon ABCDE and A'B'C'D'E coincide at 4 values of (a)
The angle where pentagon ABCDE and pentagon A'B'C'D'E coincide is:
\(\mathbf{\theta = \frac{360}{5}}\)
\(\mathbf{\theta = 72}\)
Other angles between 0 and 360 degrees, where pentagon ABCDE and pentagon A'B'C'D'E coincide are multiples of 72.
So, we have:
\(\mathbf{a = 72^o,\ 144^o,\ 216^o,\ 288^o}\)
The count of angles is 4
Hence, pentagon ABCDE and A'B'C'D'E coincide at 4 values of (a)

code that Calculate what weekday it is calcWeekday day(int), input= month(str), output= weekday (str) Returns the weekday of the date year (int) (Week starts on Sunday)
The formula for determining the weekday given a date is [2]: w = (day + b2.6m − 0.2c − 2(cm − 1) + y + by/4c + b(cm − 1)/4c)mod7
where w is the inumeric value for the "weekday" (0=Sun,... ,6=Sat), d is the day, m is the "month", y is the year, and cm is the modified "century" (cm = c -1) applied only when the year is a new century (1800, 1900, 2000, 2100) and the month is either January or February (otherwise cm = c). The mnemonic to determine the number of days in a month is [3]:
Answers
To calculate the weekday without code, use the formula: w = (day + int(2.6 * \(month_num\) - 0.2 * century - 2 * (cm - 1) + year + year // 4 + cm // 4)) % 7. Convert the numeric weekday value (0-6) to the weekday name (Sunday-Saturday). For example, July 1, 2023, is a Saturday.
Without writing any code, you can perform the following steps to determine the weekday:
1. Determine the modified century (cm):
- Divide the year by 100 to get the century.
- If the month is either January or February and the century is divisible by 4, subtract 1 from the century. Otherwise, use the original century.
2. Convert the month name to the corresponding month number:
- Assign a number to each month: January = 1, February = 2, March = 3, and so on.
3. Calculate the weekday using the formula:
- Use the formula: w = (day + int(2.6 * \(month_num\) - 0.2 * century - 2 * (cm - 1) + year + year // 4 + cm // 4)) % 7.
- Here, w is the numeric value for the weekday, ranging from 0 (Sunday) to 6 (Saturday).
4. Convert the weekday number to the weekday name:
- Assign a name to each weekday: 0 = Sunday, 1 = Monday, 2 = Tuesday, and so on.
For example, let's find the weekday of July 1, 2023:
1. Determine the modified century:
- Year = 2023, Century = 20, cm = 20 - 1 = 19.
2. Convert the month name to the month number:
- July corresponds to month number 7.
3. Calculate the weekday using the formula:
- w = (1 + int(2.6 * 7 - 0.2 * 20 - 2 * (19 - 1) + 2023 + 2023 // 4 + 19 // 4)) % 7
- w = (1 + int(18.2 - 4 - 36 + 2023 + 505 + 4)) % 7
- w = (1 + int(2512.2)) % 7
- w = 1 + 2512 % 7
- w = 1 + 5
- w = 6
4. Convert the weekday number to the weekday name:
- The weekday is Saturday.
Therefore, July 1, 2023, falls on a Saturday.

How to calculate the volume of a rectangle prism?
Answers
Answer: The formula to calculate the volume of a rectangular prism is:
Volume = length x width x height
Where:
"length" is the distance along the longest side of the prism.
"width" is the distance along the side of the prism perpendicular to the length.
"height" is the distance perpendicular to both the length and width.
So, to calculate the volume of a rectangular prism, you need to know the length, width, and height, then plug those values into the formula and perform the calculation.
For example, let's say you have a rectangular prism with a length of 10 cm, a width of 5 cm, and a height of 2 cm. The calculation would be:
Volume = length x width x height = 10 x 5 x 2 = 100 cm^3
So, the volume of the rectangular prism is 100 cubic centimeters.
