4) The length and width of a rectangular box
are 10 in. and 8 in., respectively. Another
rectangular box has a length of 15 in. and a
width of 12 in. respectively. Are the length
and width dimensions of the two rectangular
boxes similar?
Answer:
Step-by-step explanation:
Yes, the length and width dimensions of the two rectangular boxes are similar.
Two objects are considered similar if they have the same shape, but not necessarily the same size. The ratio of the corresponding sides of two similar objects is called the scale factor.
For the first rectangular box, the ratio of length to width is 10/8, which can be simplified to 5/4.
For the second rectangular box, the ratio of length to width is 15/12, which can be simplified to 5/4 as well.
Since the ratio of the corresponding sides of the two boxes is the same, namely 5/4, we can conclude that the length and width dimensions of the two rectangular boxes are similar.

The measure of side AC of the right triangle is 7.2 units.
What is the measure of side AC?The figure in the image is the of a right triangle.
Angle A = 51 degreeOpposite to angle A = BC = 8.9Adjacent to angle A = ACTo solve for the measure of side AC, we use trigonometric ratio.
The six trigonometric ratios are sine (sin), cosine (cos), tangent (tan), cotangent (cot), cosecant (cosec), and secant (sec).
Tangent = Opposite / Adjacent
tan( A ) = BC / AC
Plug in the values and solve for side AC.
tan( 51° ) = 8.9 / AC
AC = 8.9 / tan( 51° )
AC = 8.9 / 1.234897
AC = 7.2
Therefore, side AC has a value of 7.2 units.

How do I evaluate the limit? How do I know which theorems to use
In the polynomial function given, the value of the limit as it approached infinity is 5/3
What is the value of the limitTo evaluate this limit, we need to determine the behavior of the function as x approaches infinity. To do this, we can use the fact that for any polynomial p(x) and q(x) of the same degree, the limit of p(x)/q(x) as x approaches infinity is equal to the ratio of the leading coefficients.
In this case, both the numerator and denominator are polynomials of degree 2, so we can apply this property. The leading coefficient of the numerator is 6 and the leading coefficient of the denominator is 7. Therefore, the limit as x approaches infinity of the given expression is:
lim [ (6x² - 5) / (7x² + x - 3)]
x → ∞ = 5/3
Therefore, the limit of the given expression as x approaches infinity is equal to 5/3.

The table at right shows speed limits in some foreign countries in kilometers per hour. One kilometer is equal to 0.6 miles. What are these speed limits in miles per hour?
As an example, the 78-mph speed limit in the United States is equivalent to the 130 km/h restriction in Germany.
How quick is that speed?
A connection with a speed of 100 Mbps or higher is considered fast internet. Broadband internet speed is defined by the federal communications regulator (FCC) as 25 Mbps for downloading and 3 Mbps for upload.
We can increase each number by 0.6 to convert overall speed limitations from kilometers per hour into miles per hour. Here is the revised table:
Country Speed Limit (km/h) Speed Limit (mph)
Germany 130 78
France 110 66
Italy 150 90
Japan 100 60
Australia 110 66

The Panther I traveled approximately 2413 miles before reaching a speed of 130 mph.
What is a trapezoid?A trapezoid is a quadrilateral having two parallel bases and one set of other sides called legs.
To estimate the distance traveled by the Panther I, we need to approximate the area under the velocity curve between 0 and 25.7 seconds. We can divide the area into trapezoids using the data given in the table.
The first trapezoid has a height of 30 mph and a base of 1.8 seconds. The second trapezoid has a height of 40 mph and a base of 1.3 seconds (the difference between 3.1 and 1.8).
Continuing in this way, we get the following table:
Speed Height
Range (mph) Base (s) Area (mph * s)
0-30 30 1.8 54
30-40 40 1.3 52
40-50 50 1.1 55

100-120 120 6.3 756
120-130 130 4.8 624
To find the total area, we add up the areas of all the trapezoids:
54 + 52 + 55 + 78 + 133 + 144 + 207 + 310 + 756 + 624 = 2413

The graph shows the total cost c of buying one large bucket of popcorn and d large drinks. Write an equation from the graph that could be used to find the total cost c if you buy one large bucket of popcorn and d large drinks.
Answer:
[tex]y = 4d + 8\\[/tex]
Step-by-step explanation:
Since d is the number of large drinks, and there is always a constant of 1 large popcorn, we go to (0, 8). This concludes that since we start off with the cost of 8 dollars with no large drink but a large popcorn, the popcorn will stay a constant cost of $8. (the equation for this scenario is as shown):
y = md + 8
y (total cost)
m (coefficient - in this sense the cost of the drinks.)
d (amount of drinks)
8 (the constant of 8 represents the cost of one large popcorn consistently)
Now, lets find the cost of the dink.
Go to (1, 12).
$12 dollars is the total cost, with one drink and one large popcorn bought.
We have already discussed that we will have a constant of 8 because no matter the amount of drinks we will get, we would have bought 1 large popcorn at $8.
Therefore, we must subtract 8 dollars from 12.
12 - 8 = 4
From the total cost of everything we bought (2 things) and subtracting it with the cost one of the things we bought, we get the cost of the other thing.
each drink will cost $4.
Therefore, with all the variables and their listed meanings, this will be our given equation:
y = 4d + 8
If the short leg of a 30-60-90 triangle measures 203, the long leg measures how much ?
We can state this by responding to the provided question Hence, the triangle longer limb is around 351.42 in length.
What precisely is a triangle?A triangle is a polygon because it includes four or so additional parts. It features a simple rectangular shape. A rectangle having edges A, B, and C is referred to as a triangle. When the sides are actually not collinear, Euclidean geometry yields a single plane and cube. If a triangle contains three parts and three angles, it is a polygon. The intersections of a triangle's three sides are referred to as its corners. The sum of a triangle's sides is 180 degrees.
In a triangle with three legs measuring 30, 60, and 90, the shorter leg is half as long as the hypotenuse while the larger leg is sqrt3 times as long.
Let's name the larger leg's length "x" for simplicity. Thus, we are aware of:
The shorter leg measures 203 in length.
The hypotenuse measures 406 times the length of the shorter leg.
Using the proportion of the hypotenuse and leg lengths in a 30-60-90 triangle, we may find:
x = sqrt3 times ($) 203 = 351.42$
Hence, the longer limb is around 351.42 in length.
