According to the information, we plan to have cruising speed on for a minimum of 3 hours and a maximum of 4.1 hours.

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:

So 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:

So the maximum time would be 4.1 hours.

The value of ∠E = 31 degrees and the value of ∠G = 149 degrees for the given triangle.

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.

We can make advantage of the distributive property of multiplication over addition, which says that a(b + c) = ab + ac. As a result, -55 is the simplified expression.

When you multiply a value by a sum, the distributive property of multiplication over addition is put to use. For instance, you wish to multiply 5 by the product of 10 plus 3. Since the numbers are similar terms, we typically add the numbers first and then multiply by 5=> 5(10 + 3) = 65.

An algebraic principle known as the distributive property indicates that it is necessary to multiply each of the two integers by the factor being multiplied by the sum or difference of two terms.

Using this property, we can expand the expression as follows:

(2 − 3)(7 2 − + 8) = 2(7 2 − + 8) − 3(7 2 − + 8)

Now we can simplify each term separately:

2(7 2 − + 8) = 2(49 − 2 + 8) = 2(55) = 110

and

−3(7 2 − + 8) = −3(49 − 2 + 8) = −3(55) = −165

Therefore, putting the results together, we have:

(2 − 3)(7 2 − + 8) = 110 − 165 = -55

If Kirk had worked for 7 hours he would have made 42 kg of dough.

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

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.

Sipho earned R33.15 in simple interest.

The balance of the account at the end of the first 30 days was R2 133.15.

a. 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

The number of strings where exactly two of the ones are next to each other, while the third one is not next to the other two, is (n-1) x (n-2).

In combinatorics, one of the fundamental concepts is counting the number of strings or sequences of symbols that satisfy certain conditions.

Let us first consider the case where the two ones that are next to each other are at the beginning of the string. In this case, we can place the third one in any of the remaining positions, which are n-2, where n is the total length of the string. Therefore, the number of such strings is (n-2).

Similarly, if the two ones are at the end of the string, we can place the third one in any of the n-2 remaining positions, and the number of such strings is again (n-2).

Now let us consider the case where the two ones are in the middle of the string. In this case, we can place the two adjacent ones in (n-2) ways, and the third one can be placed in any of the remaining n-3 positions, since it cannot be adjacent to the other two ones. Therefore, the number of such strings is (n-2) x (n-3).

To get the total number of strings that satisfy the given condition, we need to add up the number of strings in each of the three cases:

Total number of strings = (n-2) + (n-2) + (n-2) x (n-3)

Simplifying this expression, we get:

Total number of strings = (n-1) x (n-2)

Using the definition of congruent triangles, the missing values are:

x = 35

y = 30°

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

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
