Answer : The number of views expected to be four weeks from now is, 42
Step-by-step explanation :
Formula for exponential growth is :
[tex]y=a(1+r)^x[/tex]
where,
y = exponential growth = ?
a = initial amount of growth = 20
r = growth rate = 20% = 0.20
x = number of time intervals that have passed = 4
Now put all the given values in the above formula, we get:
[tex]y=20\times (1+0.20)^4[/tex]
[tex]y=41.475\aaprox 42[/tex]
Thus, the number of views expected to be four weeks from now is, 42

What does it mean to say that a shape has an area of 8 square inches?
Final answer:
To say a shape has an area of 8 square inches means the shape covers 8 units of square inches. For similar shapes, the area comparison is the square of their scale factor; hence, if one shape's dimensions are twice another's, its area is four times larger.
Explanation:
When it is said that a shape has an area of 8 square inches, it means that the surface enclosed by the shape covers 8 units of square inches. In other words, you could fit 8 squares, each measuring 1 inch by 1 inch, inside the shape without overlapping or leaving any space inside the shape uncovered. To understand how the area of similar shapes compares, we can look into the problem involving two squares.
Marta has one square with a side length of 4 inches. A similar square has dimensions that are twice as large, meaning its side lengths are 8 inches. The area of the smaller square can be calculated as 4 inches x 4 inches, which equals 16 square inches. The area of the larger square would be 8 inches x 8 inches, resulting in 64 square inches. The ratio comparing the two areas is 64:16, which simplifies down to 4:1. This shows that the larger square's area is four times greater than that of the smaller square.
An area of 8 square inches means the shape covers a space equivalent to eight 1-inch by 1-inch squares.
To say that a shape has an area of 8 square inches means that the amount of space enclosed within the boundaries of the shape is equivalent to the area of eight 1-inch by 1-inch squares. Imagine a piece of graph paper where each small square is 1 inch by 1 inch.If the shape could be perfectly copied onto the graph paper, you would find that it covers eight of those squares.For example, an area of 8 square inches could be visualized by a variety of shapes: a rectangle measuring 2 inches by 4 inches or even an irregular shape that neatly fits inside the same area.In mathematics, there are various ways to calculate the area depending on the shape. For regular shapes like rectangles and circles, formulas are often used. But the fundamental idea of area — the measure of the space inside a shape — remains the same.you can buy 5 cans of green beans at the Village Market for $2.20 you can buy at 10 of the same cans of beans at Sam's Club for $5.10 Which places is the better buy

Please help me with this problem.
The diagram shows the floor plan of a one-bedroom apartment. Find the area of the living room in square feet. Round to nearest square foot.
The area of the living room is approximately 238 square feet.
To find the area of the living room, we need to multiply its length by its width.
First, let's convert the dimensions from feet and inches to feet. We have:
Length: 12 feet + 4 inches = 12 + 4/12 = 12.33 feet
Width: 19 feet + 4 inches = 19 + 4/12 = 19.33 feet
Now, we can multiply the length and width to find the area:
Area = length × width = 12.33 feet × 19.33 feet = 238.1289 square feet
Rounding to the nearest whole square foot, the area of the living room is approximately 238 square feet.
Please help me with this problem.
The diagram shows the floor plan of a one-bedroom apartment. Find the area of the living room in square feet. Round to nearest square foot.
The dimensions of living room are 12' 4" x 19' 4"
On rounding off to nearest feet we get the area of the living room as 238 ft²
In the figure it is given that the dimensions of the living room are 12' 4" x 19' 4". This means that the dimensions are:
12 ft 4 in x 19 ft 4 in
To get the area in feet, we need to convert the dimensions into feet. This can be done by using the conversion factor that 1 foot = 12 inch
So, 12 ft 4 in can be converted into feet as follows:
[tex]12\ \text{ft}\ 4\ \text{in} = 12\ \text{ft}\ + \frac{4}{12}\ \text{ft} = 12.333\ \text{ft}[/tex]
19 ft 4 in can be converted into feet as follows:
[tex]19\ \text{ft}\ 4\ \text{in} = 19\ \text{ft}\ + \frac{4}{12}\ \text{ft} = 19.333\ \text{ft}[/tex]
Now to calculate the area we multiply the dimensions of the living room (as the living room is a rectangle and area of rectangle is product of its length and breadth):
[tex]area = 12.333 \times 19.333 =238.433889[/tex] ft²
On rounding of to nearest feet we get the area as 238 ft². So, the area of the living room is 238 ft²
Line v passes through point (6, 6) and is perpendicular to the graph of y = 34x – 11. Line w is parallel to line v and passes through point (–6, 10). Which is the equation of line w in slope-intercept form?
Answer:
y = -1/34 . x + 167/17
Step-by-step explanation:
The slope-intercept form of a linear equation is:
y = m.x + b
where,
m is the slope
b is the y-intercept
Line v is perpendicular to the graph of y = 34 x - 11. If 2 lines are perpendicular, the slope of one is the inverse and opposite of the other. Then, the slope of v is -1/34.
Line w is parallel to line v. When 2 lines are parallel, they have the same slope.
The equation of w is:
y = -1/34 . x + b
Lines b passes through the point (-6, 10). We can replace this ordered pair in the previous equation to find the value of b.
10 = -1/34 . (-6) + b
b = 167/17
The equation of w is:
y = -1/34 . x + 167/17

Elise is measuring the angles of a triangle. She measures the first two and gets 30° and 100°. What should be the measure of the third angle?
A) 50°
B) 60°
C) 130°
D) 230°
The measure of the third angle is 50 degrees for the given triangle. The correct answer would be an option (A).
What is a Triangle?Triangle is defined as a basic polygonal shape of a triangle that has three sides and three interior angles. It is one of the fundamental shapes in geometry and is represented by the symbolΔ.
Let x be the measure of the third angle.
As we know that the sum of interior angles in the triangle is always 180 degrees.
So, as per the given question, we have
30° + 100° + x = 180°
130° + x = 180°
x = 180° - 130°
Apply the subtraction operation, and we get
x = 50°
Thus, the measure of the third angle is 50 degrees.
