Final answer:
The video with an initial 38,000 views will have approximately 74,480 views in 2 hours when it is increasing by 40% every hour.
Explanation:
To calculate the number of views a video will have in 2 hours if it is increasing by 40% every hour, we will use the formula for percentage growth. Initially, the video has 38,000 views. After one hour, the views will be increased by 40%, and after two hours, this new amount will again be increased by 40%. The formula for calculating the number of views after each hour is:
Views after n hours = Initial views × [tex](1 + growth rate)^n[/tex]
Where:
Initial views = 38,000
Growth rate = 40% = 0.40 (as a decimal)
n = number of hours
After 1 hour:
Views after 1 hour = 38,000 × (1 + 0.40)^1
Views after 1 hour = 38,000 × 1.40 = 53,200
After the second hour, we will use the number of views from the first hour to calculate the increase:
Views after 2 hours = 53,200 × [tex](1 + 0.40)^1[/tex]
Views after 2 hours = 53,200 × 1.40 = 74,480
Therefore, the video will have approximately 74,480 views in 2 hours.
T-Shirts R Us advertises shirts as shown below. mc002-1.jpg Which quantities in the advertisement represent a unit rate?
Answer:
C.) $10 per shirt
Step-by-step explanation:
have a nice day
The option C is more simplified answer for given condition, unit rate is $10.
What is unit rate?When comparing two different kinds of numbers with distinct units, a rate is a ratio that is employed. The unit rate, on the other hand, shows how many units of one quantity are equal to one unit of another. When the rate's denominator is 1, we refer to the rate as a unit rate.
Given
There are 5 shirts in the image given to us composed of 3 white shirts and 2 black shirts.
A rate with 1 as its denominator is known as a unit rate.
Option A: A ratio of 3:2 or a fraction of 3/2 is indicated by 3 white shirts and 2 white black shirts.
The denominator is not 1, hence this cannot be a unit rate.
Option B: 5 white shirts to 2 black shirts. This cannot be a unit rate because the fraction 2/5 will not have 1 as the denominator.
Choice C: $10 for each shirt. Because it represents a ratio of 10:1 or a fraction of 10/1, this rate is a unit rate. Therefore, the price of 5 shirts will be $50.
D: $50 for each shirt. Because option C has provided us with a more straightforward sum of $10, which we must accept as we are dealing with unit rates, this would not be a unit rate in this question.
Hence Option C is most suitable answer.

What is right triangle?Right triangle is defined as a triangle which one angle is a right angle or two sides are perpendicular.
What is Pythagoras theorem?A right-angled triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.
perpendicular² + base² = hypotenuse²
Given,
Side length of each triangle = 4 feet
Hypotenuse of each triangle = 9 feet
Shared side = x
Given the triangles are right angled,
According to Pythagoras theorem,
a² + b² = c²
Here, a = 4 , b = x , c= 9
Substitute the values in Pythagoras theorem,
4² + x² = 9²
16 + x² = 81
x² = 81 - 16
x² = 65
Taking square root on both sides
x = √65
x = 8.062
x = 8.1 (Rounding nearest tenth)
Hence, the center height of tent is 8.1 feet.

How would you solve 1/8 divided by 6
The required 1/8 divided by 6 is equal to 1/48.
To solve 1/8 divided by 6, we can rewrite it as a fraction. The reciprocal of 6 is 1/6, so the division problem becomes (1/8) * (1/6). To multiply fractions, we multiply the numerators together and the denominators together.
Step 1 is given as:
= (1/8) * (1/6)
Step 2(simplification) is given as:
= 1 * 1 / 8 * 6
= 1/48
Therefore, the required 1/8 divided by 6 is equal to 1/48.

Sunny's garden has 9 tomato plants, 5 pepper plants, 3 squash plants, and 6 pumpkin plants. For every 3 tomato plants in Sunny's garden, there is 1 ____ plant.
Answer: Squash plant is the right answer to fill the blank.
Step-by-step explanation:
Since we have given that
Number of tomato plants = 9
Number of pepper plants = 5
Number of squash plants = 3
Number of pumpkin plants = 6
Since the ratio of tomato plants to squash plants is 9 : 3 = 3 : 1.
So, for every 3 tomato plants in Sunny's garden, there is 1 squash plant.
Hence, Squash plant is the right answer to fill the blank.
Which of the following statements is true? If two polygons are similar, then the corresponding sides are proportional and the corresponding angles are proportional. If two polygons are similar, then the corresponding sides are proportional and the corresponding angles are congruent. If two polygons are similar, then the corresponding sides are congruent and the corresponding angles are proportional. None of the choices are correct.
The correct statement is that if two polygons are similar, their corresponding sides are proportional while their corresponding angles are congruent. Similar polygons have the same shape but can have different sizes, and this applies across various geometrical figures and principles, like the Pythagorean theorem in the context of right triangles.
Explanation:The correct statement among the given options is: If two polygons are similar, then the corresponding sides are proportional and the corresponding angles are congruent. When polygons are similar, this means their shapes are geometrically the same but they may differ in size. The ratios of the lengths of corresponding sides of similar polygons are equal, which is true for any pairs of similar polygons, not just triangles. The corresponding angles, on the other hand, are congruent, which means they have the same measure in both polygons.
To explain this concept, we use different examples in geometry. For instance, in similar triangles, not only are the three angles in one triangle congruent to the three angles in the other, but also the sides are proportional, which can be expressed as the ratio of any two corresponding sides in the two triangles being equal. This proportional relationship is a key characteristic of similarity in geometry.
Moreover, a statement like the Pythagorean theorem applies to right triangles, stating that the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides. This theorem is connected to similarity because one can generate a family of similar right triangles by scaling a single right triangle.

Given a mean of 24.5 and a standard deviation of 1.7, within how many standard deviations of the mean do the values 24, 23, 28, 23, 24, and 25 fall?
Given mean = 24.5 and standard deviation = 1.7
Within 1 standard deviations, x ∈ [24.5 - 1.7 , 24.5 + 1.7] or [22.8 , 26.2].
Within 2 standard deviations, x ∈ [24.5 - 2(1.7) , 24.5 + 2(1.7)] or [21.1 , 27.9].
Within 3 standard deviations, x ∈ [24.5 - 3(1.7) , 24.5 + 3(1.7)] or [19.4 , 29.6].
Given values are 24, 23, 28, 23, 24, and 25.
So {24, 23, 23, 24, 25} fall within 1 standard deviation and {28} falls within 3 standard deviations.

mean median mode range on 83 75 74 40 85 64 23 68
In the given set, the mean is 64, the median is 66, there is no mode, and the range is 62.
To find the mean, median, mode, and range of the given set of numbers: 83, 75, 74, 40, 85, 64, 23, 68.
1. Mean:
[tex]\[ \text{Mean} = \frac{\text{Sum of all numbers}}{\text{Total number of numbers}} \][/tex]
[tex]\[ \text{Mean} = \frac{83 + 75 + 74 + 40 + 85 + 64 + 23 + 68}{8} \][/tex]
[tex]\[ \text{Mean} = \frac{512}{8} \][/tex]
[tex]\[ \text{Mean} = 64 \][/tex]
2. Median:
The median is the middle number when the numbers are arranged in ascending order.
Arranging the numbers in ascending order: 23, 40, 64, 68, 74, 75, 83, 85
Since there are 8 numbers, the median is the average of the two middle numbers:
[tex]\[ \text{Median} = \frac{64 + 68}{2} \][/tex]
[tex]\[ \text{Median} = 66 \][/tex]
3. Mode:
The mode is the number that appears most frequently.
In this set, there is no number that appears more than once.
So, there is no mode.
4. Range:
The range is the difference between the largest and smallest numbers.
[tex]\[ \text{Range} = \text{Largest number} - \text{Smallest number} \][/tex]
[tex]\[ \text{Range} = 85 - 23 \][/tex]
[tex]\[ \text{Range} = 62 \][/tex]
So, for the given set of numbers, the mean is 64, the median is 66, there is no mode, and the range is 62.
