Answer:
7 < third side < 13
Step-by-step explanation:
The triangle inequality requires the sum of the shortest two side lengths to be more than the longest side length. The effect of that is to limit the third side to values between the sum and difference of the other two sides:
7 < third side < 13

Explain the difference between congruence and equality. Use an example. GIVING BRAINLIEST!!!!!!!!
Answer:
Congruence is a relationship of shapes and sizes, such as segments, triangles, geometrical figures, while equality is a relationship of sizes, such as lengths, widths, heights.
Congruence deals with objects while equality deals with numbers. You wont say that two shapes are equal or two numbers are congruent.

Erin is considering joining one of 2 swim clubs. The Gators Swim Club has no registration fee, but charges $105 per month. The Tidal Wave Swim Club charges members $80 per month plus a one-time registration fee of $375. For how many months is Gators the cheaper option? Use system of equations and define variables
Answer:
14 months
Step-by-step explanation:
Given
Gator's = $105 monthly charges
Tidal Wave = $375 registration fee + $80 monthly charged
Required
Determine for how many months Gators is cheaper
Let the number of months be x;
Represent the given data, algebraically.
For Gators: 105x
For Tidal Wave: 375 + 80x
Represent the above as a n inequality
Since Gators has to be cheaper; we have
[tex]105x < 375 + 80x[/tex]
Collect Like Terms
[tex]105x - 80x < 375[/tex]
[tex]25x < 375[/tex]
Divide both sides by 25

This implies that Gator's will be cheaper for months less than 15
Hence, the number of months is 14

You are studying meteorology and collect weather data for Gainesville, FL for the months of April, May, and June 2015. The function T ( x ) = .18 x + 80.25 gives an estimate of the daily high temperature during this period where x is the number of days after April 1, 2015. Evaluate T ( 57 ) (rounded to one decimal place) and then state its physical interpretation. T ( 57 ) =____________
Answer:
90.5
Step-by-step explanation:
T(57)=.18(57)+80.25
T(57)=10.26+80.25
T(57)=90.51 (round to the one descimal place)
your answer would be
T(57)=90.5
The temperature T(57) is 90.5 and it states that the temperature for 57 days from April 1 2015 is 90.5.
Given,
The function T ( x ) = .18 x + 80.25 gives an estimate of the daily high temperature during this period where x is the number of days after April 1, 2015.
We need to evaluate T ( 57 ) (rounded to one decimal place) and then state its physical interpretation.
What is a function?A function has an input and an output.
Example:
f(x) = x + 5
x = 1
f(1) = 1 + 5 = 6
1 = input
6 = output
Find T(x) at t = 57.
We have,
T(x) = 0.18 x + 80.25
T(57) = 0.18 x 57 + 80.25
T(57) = 10.26 + 80.25
T(57) = 90.51
Rounding to one decimal place.
90.51 = 90.5
T(57) = 90.5
T(57) = 90.5 means that the temperature for 57 days from April 1 2015 is 90.5
Thus the temperature T(57) is 90.5 and it states that the temperature for 57 days from April 1 2015 is 90.5.

Which of the following statements is true about a distribution that appears to have a gap when displayed as a histogram? The distribution must have an outlier. The distribution must have an outlier. A The distribution has a region between two data values where no data were observed. The distribution has a region between two data values where no data were observed. B The distribution is approximately normal. The distribution is approximately normal. C The distribution cannot be symmetric. The distribution cannot be symmetric. D The distribution must be bimodal. The distribution must be bimodal. E
Answer:
Option B is correct - The distribution has a region between two data values where no data were observed.
Step-by-step explanation:
To answer this question, i would use a sample histogram to explain the gaps in a histogram.
For example, a histogram has been attached.
The histogram has been plot to show the average height of children of different ages in a particular year.
From the attached image, we can see that all the bars represent average height of different ages.
Now, if one of the bars was to be empty which in this case means that the value there is zero and there is a gap. Since the bar is to represent average height of a particular age, it means that there was no data collected for that age as height cannot be zero!
This same reason applies generally to gaps in histogram which means that no data was collected for that particular bar region.
Thus, Option B is correct - The distribution has a region between two data values where no data were observed.

A rectangle has a perimeter of 60 inches. The length of the rectangle is 3 inches less than twice the width
What is the length of the rectangle?
Answer:
length = 19 units
Step-by-step explanation:
width = x
length = 2x-3
width = 11 units
length = 2(11)-3
length = 22-3
length = 19 units
perimeter = 11 + 11 + 19 + 19 = 60 units
The perimeter of a shape is the sum of the side lengths of the shape. The length of the rectangle is 19 units.
Given that:
[tex]Perimeter = 60[/tex]
[tex]Length = 2 \times Width -3[/tex]
The perimeter of a rectangle is:
[tex]Perimeter = 2 \times (Length + Width)[/tex]
So, we have:
[tex]60= 2 \times (2\times Width - 3+ Width)[/tex]
Divide both sides by 2
[tex]30= 2\times Width - 3+ Width[/tex]
Collect like terms
[tex]3 + 30= 2\times Width + Width[/tex]
[tex]33= 3Width[/tex]
Divide both sides by 3
[tex]11= Width[/tex]
Rewrite as:
[tex]Width = 11[/tex]
Recall that: [tex]Length = 2 \times Width -3[/tex]
[tex]Length = 2 \times 11 - 3[/tex]
[tex]Length = 22- 3[/tex]
[tex]Length = 19[/tex]
Hence, the length of the rectangle is 19 units.

If 20% of x is y, and 30% of y is z, then what percent of x is z?
Your answer is 6% of x.
We can write the given information as equations to find the answer:
Another way to write "20% of x" is to write 0.2x, so therefore 0.2x = y
You can also write "30% of y" as 0.3y, so 0.3y = z
Now we can substitute in the first equation to the second equation, as we know what y equals in terms of x:
0.3(0.2x) = z
Multiplying out we get:
0.06x = z, and 0.06 as a percentage is 6%

The diameter of a sphere is measured to be 4.17 in.
(a) Find the radius of the sphere in centimeters.
cm
(b) Find the surface area of the sphere in square centimeters.
cm2
(c) Find the volume of the sphere in cubic centimeters.
cm3
Step-by-step explanation:
To find the radius of the sphere we must convert the inches to centimeters
Using the conversation
1 inch = 2.54 cm
If 1 inch = 2.54 cm
4.17 inch = 2.54 × 4.17 = 10.59 cm
a).We can find the radius using the formula
[tex]radius = \frac{diameter}{2} [/tex]
From the question
diameter = 10.59 cm
So we have
[tex]radius = \frac{10.59}{2} [/tex]
radius = 5.30 cmb).Surface area of a sphere= 4πr²
where
r is the radius
Surface area = 4(5.30)²π
= 112.36π
= 352.989
We have the answer as
Surface area = 353 cm²c).Volume of a sphere is given by
[tex] \frac{4}{3} \pi {r}^{3} [/tex]
r = 5.30
The volume of the sphere is
[tex] \frac{4}{3} ( {5.30})^{3} \pi[/tex]
= 623.61451
We have the answer as
Volume = 623.6 cm³Hope this helps you
