Answer:
Part A: If (26)x = 1, the value of x is approximately 0.03846.
Part B: If (50)x = 1, the possible value of x is approximately 0.02.
Step-by-step explanation:
Part A: To find the value of x in the equation (26)x = 1, we need to find the value that, when raised to the power of 26, will equal 1. This value can be found by taking the reciprocal (or multiplicative inverse) of 26 and taking the natural logarithm of both sides.
Using the formula x = 1/26, we get:
x = 1/26 = 0.03846
So, the value of x in the equation (26)x = 1 is approximately 0.03846.
Part B: To find the possible values of x in the equation (50)x = 1, we need to find the values that, when raised to the power of 50, will equal 1. This value can be found by taking the reciprocal (or multiplicative inverse) of 50 and taking the natural logarithm of both sides.
Using the formula x = 1/50, we get:
x = 1/50 = 0.02
So, the possible value of x in the equation (50)x = 1 is approximately 0.02.

Kirk prepared 24 kilograms of dough after working 4 hours. How much dough did Kirk prepare if he worked for 7 hours? Solve using unit rates.
If Kirk had worked for 7 hours he would have made 42 kg of dough.
What is unit rate?A unit rate means a rate for one of something.
Given that, Kirk prepared 24 kilograms of dough after working 4 hours, we need to find the amount of dough if he worked for 7 hours.
Calculating the unit rates,
Since, he worked for 4 and made 24 kg,
So, in 1 hour = 24/4 = 6 kg
Therefore, in 1 hour he will make 6 kg
Therefore, in 7 hours he will make = 7x6 = 42 kg
Hence, If Kirk had worked for 7 hours he would have made 42 kg of dough.

The value of ∠E = 31 degrees and the value of ∠G = 149 degrees for the given triangle.
What are similar triangles?Triangles with the same shape but different sizes are said to be similar triangles. Squares with any side length and all equilateral triangles are examples of related objects. In other words, if two triangles are similar, their corresponding sides are proportionately equal and their corresponding angles are congruent. Triangle resemblance is indicated here by the symbol "."
The two triangles are similar thus the measure of its angle are also equal.
Using the similar triangle we have:
Angle D = Angle A = 82 degrees.
Angle F = 67 degrees
Using the sum of interior angles of triangle we have:
∠D + ∠F + ∠E = 180
82 + 67 + ∠E = 180
∠E = 31
From the figure we observe that,
∠E + ∠G = 180 (straight line)
31 + ∠G = 180
∠G = 149
Hence, the value of ∠E = 31 degrees and the value of ∠G = 149 degrees for the given triangle.

According to the information, we plan to have cruising speed on for a minimum of 3 hours and a maximum of 4.1 hours.
How to calculate how many hours we are going to have the cruising speed on?To calculate how many hours we are going to have the cruising speed on we must carry out the following process:
To calculate the minimum we must subtract 35 from 215 and then divide by the speed:
215 - 35 = 180180 / 60 = 3So the minimum hours would be 3 hours.
On the other hand, to calculate the maximum we must add 35 to 215 and divide it by the speed:

The estimate for the mean book thickness is 3.2 mm.
What is mean?
In arithmetic, mean is the sum of all the added values of all the data in a set divided by the number of data in the set.
To find the mean book thickness, we can use the formula for the mean (also known as the average):
mean = (sum of all data points) / (number of data points)
Since we don't have the exact thickness of each book, but rather intervals of thickness and the number of books in each interval, we can use a weighted mean to estimate the mean thickness.
Here is the calculation:
First, we'll find the midpoint of each interval:
Interval 1: [0, 2] -> midpoint: x1 = 1
Interval 2: [2, 4] -> midpoint: x2 = 3
Interval 3: [4, 6] -> midpoint: x3 = 5
Next, we'll find the weight of each interval by multiplying the midpoint by the frequency:
Interval 1: x1 * f1 = 1 * 5 = 5
Interval 2: x2 * f2 = 3 * 8 = 24
Interval 3: x3 * f3 = 5 * 7 = 35
Finally, we'll sum up the weights and divide by the total frequency to find the weighted mean:
Weighted mean = (5 + 24 + 35) / (5 + 8 + 7) = 64 / 20 = 3.2
So, the estimate for the mean book thickness is 3.2 mm.

The requried solutions are as follows,
(1) the original price is $450. (2) the original price is $172.40.
Sale price is defined as the price of a product marked including of various price cut such as discounts.
Here,
If the percent of discount is 80% and the sale price is $90, we can use the following formula to find the original price x (let)
Sale price = Original price - Discount
$90 = x - 0.8x
Simplifying the right-hand side:
$90 = 0.2x
x = $450
Therefore, the original price is $450.
If the percent of discount is 15% and the sale price is $146.54, we can use the same formula:
Sale price = Original price - Discount
$146.54 = x - 0.15x
Simplifying the right-hand side:
$146.54 = 0.85x
x = $172.40

Katya sold
46 books at £1.40 each
32 bracelets at £1.50 each
some badges at 90p each
She got a total of £134
Work out how many badges Katya sold.
Answer:
This is a math problem. To solve it, you need to use algebra. Let me show you how.
Let x be the number of badges Katya sold. Then we can write an equation using the given information:
46 × 1.40 + 32 × 1.50 + 0.90 × x = 134
Simplifying the equation, we get:
64.4 + 48 + 0.9x = 134
Subtracting 64.4 and 48 from both sides, we get:
0.9x = 21.6
Dividing both sides by 0.9, we get:
x = 24
Therefore, Katya sold 24 badges.

The two triangles are congruent. Solve for x. Then find all missing angles.
(I found x but I don’t know how to figure out y)
Using the definition of congruent triangles, the missing values are:
x = 35
y = 30°
What are Congruent Triangles?Given that the two triangles in the image above are congruent, it implies that all its corresponding angles and corresponding side lengths have equal measure.
Therefore, we have:
2x - 10 = x + 25
Solve for x:
2x - x = 10 + 25
x = 35
Plug in the value of x to find the missing angles:
y + 90 + (2x - 10) = 180 [triangle sum theorem]
y + 90 + (2(35) - 10) = 180
y + 90 + 60 = 180

Answer:
The value of the investment in 5 years.
Step-by-step explanation:
The description of the function states that it tells us the value of an investment at some point in the future (t), measured in years. In other words, f(t). When the time is 5 years, it would be written as f(5), and the t term in the function will be set to 5 for the calculation, which will yield the value of the investment at that time.
In any set of positive integers the replacement of a set of three 2s with a set of two threes will not change the sum
The statement is incorrect. The replacement of three 2s with two threes will change the sum.
For example, consider the set {2, 2, 2}. The sum of this set is 6. However, if we replace three 2s with two threes, the new set becomes {3, 3}, and its sum is 6, which is different from the original sum. Hence, replacing a set of three 2s with a set of two threes does change the sum. An integer is a whole number that can be positive, negative, or zero. Integers are numbers that don't have any fractional or decimal component. Some examples of integers are: -5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5, and so on. The set of integers is denoted by the symbol "Z", which stands for Zahlen, the German word for "numbers".

What was the balance of the account at the end of the first 30 days?
Sipho earned R33.15 in simple interest.
The balance of the account at the end of the first 30 days was R2 133.15.
How to calculate thisa. To calculate the simple interest earned by Sipho, we need to calculate the total amount deposited and the interest earned on that amount.
Total amount deposited = R600 + R1 000 + R500 = R2 100
Interest earned = R2 100 x 4.5% x 30/365 = R33.15 (rounded to the nearest cent)
Therefore, Sipho earned R33.15 in simple interest.
b. The balance of the account at the end of the first 30 days can be calculated by adding the total amount deposited and the interest earned to the initial deposit:
Balance = R600 + R1 000 + R500 + R33.15 = R2 133.15
Therefore, the balance of the account at the end of the first 30 days was R2 133.15.
