Answer: 85.7

Step-by-step explanation:

Option (O log 7) refers to the base-10 logarithm of 7, represented as log10(7), which is not the same as ln (7). Optional (O log, 10) and (O log, e) mathematical expressions are not acceptable.

In mathematics, the logarithm is the reciprocal of a power. As a result, the exponent by which b must be raised to achieve a number x matches its logarithm in base b. For example, because 1000 = 103, the base-10 logarithm is 3, or log10 = 3. For example, the base 10 logarithm of 10 is 2, but the square of 10 is 100. Log 100 = 2. A logarithm (or log) is the mathematical word used to answer questions such as how many times a base of 10 must be multiplied by itself to get 1,000. The answer is 3 (1,000 = 10 10 10).

When you compute (In), you are calculating the natural logarithm of 7, which is indicated as ln(7) or loge (7).

As a result, the expression you'd be looking up the value of is: ln(7) or loge (7).

Option (O log 7) refers to the base-10 logarithm of 7, represented as log10(7), which is not the same as ln (7). Optional (O log, 10) and (O log, e) mathematical expressions are not acceptable.

Answer:

The answer is 4.8 kg. Just do 6 x 0.8                                                                                                        

Answer:

2/6 or 1/3

Step-by-step explanation:

To find probability, we have to look at the favorable outcome (the outcome we're looking for - in this case, rolling greater than a 4) divided by the total outcomes (the total possible outcomes - in this case, 6).

There are 6 sides on a dice, as laid out in the question. How many numbers on a dice are greater than 4? Well, 5 and 6, of course. These are only two sides of the dice, so our probability would be 2/6, or simplified, 1/3, and that's our answer.

If you'd like a more in-depth explanation, please let me know and I'd be happy to help. :)

Answer:

It would be the same numbers just without a decimal.

Step-by-step explanation:

21.39 + 21.59=42.89

2139 + 2159=4289

You just have to figure out where the decimal will go.

The rate of interest compounded annually is 6.4 %.

Compound interest is the interest we earn on both principle and interest.

Nanuk in his savings account had 2000 euros which became 2545.10 in 4 years compounded annually.

Here, Amount(A) = 2545.10, Principle(P) = 2000, Time in years(n) = 4 and we have determine the rate of interest which is r.

We know, For compound interest A = P( 1 + r/100)ⁿ which is,

\((\frac{A}{P})^\frac{1}{n}\) \(= ( 1 + \frac{r}{100})\).

\((\frac{A}{P})^\frac{1}{n} - 1 = \frac{r}{100}\).

\((\frac{2545.1}{2000})^\frac{1}{4} - 1 = \frac{r}{100}\).

\((1.28)^\frac{1}{4} - 1 = \frac{r}{100}\).

\(1.064 - 1 = \frac{r}{100}\).

\(0.064 = \frac{r}{100}\).

\(r = 6.4\).

Area = \(\frac{(a + b)h}{2}\) = \(\frac{(6 + 13)(5)}{2}\) = \(\frac{(19)(5)}{2}\) = \(\frac{95}{2}\) = 47.5 cm

Answer:it will be D

Step-by-step explanation: because $100 + 4%=$100.4

The surface area of the figure is approximately 997.5π cm².

We have,

The figure has two shapes:

Cone and a semicircle

Now,

The surface area of a cone:

= πr (r + l)

where r is the radius of the base and l is the slant height.

Given that

r = 15 cm and l = 19 cm, we can substitute these values into the formula:

= π(15)(15 + 19) = 885π cm² (rounded to the nearest whole number)

The surface area of a semicircle:

= (πr²) / 2

Given that r = 15 cm, we can substitute this value into the formula:

= (π(15)²) / 2

= 112.5π cm² (rounded to one decimal place)

The surface area of the figure:

To find the total surface area of the figure, we add the surface area of the cone and the surface area of the semicircle:

Now,

Total surface area

= 885π + 112.5π

= 997.5π cm² (rounded to one decimal place)

Therefore,

The surface area of the figure is approximately 997.5π cm².

One bag of popcorn costs $7.

The question asks for the cost of one bag of popcorn based on the given information. Let's solve this step by step:

1. We are given that the first family bought 5 bags of popcorn and 6 souvenir cups for a total of $65.
2. The second family bought 10 bags of popcorn and 4 souvenir cups for a total of $90.

To find the cost of one bag of popcorn, we can set up a system of equations:

Let's say the cost of one bag of popcorn is x dollars and the cost of one souvenir cup is y dollars.

From the first family's purchase:
5x + 6y = 65

From the second family's purchase:
10x + 4y = 90

To solve this system of equations, we can use the method of substitution or elimination.

Let's use the method of elimination:

Multiply the first equation by 2 and the second equation by 3 to make the coefficients of x equal:

10x + 12y = 130
30x + 12y = 270

Now, subtract the second equation from the first equation:

(10x + 12y) - (30x + 12y) = 130 - 270
-20x = -140
x = -140 / -20
x = 7

The general solution to the differential equation based on the information is y(x) = (1/2) x^4 e^(-3x) + C e^(-3x)

Based on the information, dy/dx + 3y = 2x³ e^(-3x)

The integrating factor is e^(∫3 dx) = e^(3x),

e^(3x) dy/dx + 3e^(3x) y = 2x^3 e^(3x - 3x)

d/dx (e^(3x) y) = 2x^3

e^(3x) y = ∫2x^3 dx = (1/2)x^4 + C

C is an arbitrary constant of integration.

The Product of 1 5/8, 2, and 3/5 is equal to 39/20, which is simplified completely. The answer is 39/20.

To find the product and simplify completely, you need to perform multiplication and simplify the resulting fraction. Here, we are multiplying the following fractions and mixed numbers:1, 5/8, 2, and 3/5.The first step is to convert the mixed numbers into improper fractions.

We do that by multiplying the whole number by the denominator, and then adding the numerator.For 1 5/8, we get:$$1 \frac{5}{8} = \frac{8}{8} \times 1 + \frac{5}{8} = \frac{13}{8}$$For 2, we get:$$2 = \frac{2}{1} = 2 \times \frac{1}{1} = \frac{2}{1}$$For 3/5, we leave it as is since it's already a fraction.

Now that we have all the numbers as fractions, we can multiply them:$$\frac{13}{8} \times \frac{2}{1} \times \frac{3}{5} = \frac{13 \times 2 \times 3}{8 \times 1 \times 5} = \frac{78}{40}$$

To simplify the fraction, we can divide both the numerator and denominator by their greatest common factor, which is 2:$$\frac{78}{40} = \frac{2 \times 39}{2 \times 20} = \frac{39}{20}$$

Therefore, the product of 1 5/8, 2, and 3/5 is equal to 39/20, which is simplified completely. The answer is 39/20.

The probability that a student who attends the first session also attends the second session is 1/3

Evaluating the probability

We can approach this problem by using conditional probability.

Let's use the notation "S1" to represent the event that a student attends the first session, and "S2" to represent the event that a student attends the second session.

Then we can use the formula for conditional probability:

P(S2 | S1) = P(S1 and S2) / P(S1)

We know that P(S1) = 0.6, since 60% of students attend the first session. We also know that P(S1 and S2) = 0.2, since 20% of students attend both sessions.

So we can plug in these values and solve for P(S2 | S1):

P(S2 | S1) = 0.2 / 0.6

P(S2 | S1) = 1/3

Therefore, the probability that a student who attends is 1/3 or approximately 0.333.
