Given:
Kelly spends 5 hours each week playing softball and 4 hours each week practicing her violin.
To find:
The ratio of hours spent practicing violin to hours spent playing softball three different ways.
Solution:
We have,
Time spend on Softball = 5 hours
Time spend on Violin = 4 hours
The ratio to hours spent practicing violin to hours spent playing softball is
[tex]\text{Required ratio}=\dfrac{\text{Time spend on Violin}}{\text{Time spend on Softball}}[/tex]
[tex]\text{Required ratio}=\dfrac{4}{5}[/tex]
It can be written as
[tex]\text{Required ratio}=4:5[/tex]
[tex]\text{Required ratio}=4\text{ to }5[/tex]
Therefore, the ratio of hours spent practicing violin to hours spent playing softball three different ways are [tex]\dfrac{4}{5}, 4:5[/tex] and 4 to 5.

Jim is making frozen juice treats that are in the shape of a cone. The molds he bought are each 3 inches (in.) deep with a diameter of 3 in. What is the approximate volume of juice needed for Jim to make 6 juice treats?
Answer:
42.42 in³ volume of juice
Step-by-step explanation:
Jim is making frozen juice treats that are in the shape of a cone.
The volume of a cone = πr²h/3
From the above question:
h = 3 inches
Diameter = 3 inches
Radius = Diameter/2
= 3/2
= 1.5 inches
The volume for 1 frozen treat =
= π × 1.5² × 3/3
= 7.07 in³
The approximate volume of juice needed for Jim to make 6 juice treats
is calculated as:
1 juice treat = 7.07 in³
6 juice treats = x
Cross Multiply
x = 6 × 7.07 in³
x = 42.42 in³

The side lengths of a triangle are 7, 24, and 25. Is this triangle a right triangle?
A) yes
b) no
c) not enough information
Answer:
yes
Step-by-step explanation:
for it to be a right triangle you should be able to add two of the sides and it be greater than the third side. 7 + 24 > 25
24 + 25 > 7
7 + 25 > 24 therefore it is indeed a right triangle

Answer and Step-by-step explanation: The definition of polynomial is "poly" meaning many and Nominal, which means terms. So, Polynomial is an expression of constants, variables, exponents that are combined using mathematical operators: addition, subtraction, multiplication and division.
However, there are exceptions:
Polynomial don't have negative exponent;Polynomial cannot be divided by a variable;Variable cannot be inside a radical;The degree of a polynomial is the highest exponent of that variable. For example for polynomial [tex]3x^5+6x-5x^{2}[/tex] , the degree is 5.
Polynomials have 3 different types:
monomial: only has one term;binomial: has 2 terms;trinomial: has 3 terms;Now, analysing each expression given by the alternatives above:
1. It is a polynomial of degree 3 and trinomial.
2. It is a polynomial of degree 2 and trinomial.
3. Yes, its a polynomial of degree 2 and monomial.
4. It is not a polynomial because it is divided by a variable.
5. A polynomial of degree 5 and it's a binomial.
6. It is not a polynomial due to the exponent being negative.

The following table shows the number of hours some high school students in two towns spend watching TV each week:
Town A 16 25 42 38 17 32 42 10 17
Town B 8 0 0 17 30 8 21 9 19
Part A: Create a five-number summary and calculate the interquartile range for the two sets of data. (6 points)
Part B: Are the box plots symmetric? Justify your answer. (4 points)
(10 points)
Answer:
Step-by-step explanation:
The first step is to put the data in order, as shown in the diagram below
Five summaries of Town A
Lowest Value = 10
Lower Quartile, = 16.5 (The value falls between 16 and 17)
Median, = 25
Upper Quartile, = 40 (The middle value between 38 and 42)
Highest value = 42
Five summaries of Town B
Lowest value = 0
Lower Quartile, = 4 (The middle value between 0 and 8)
Median, = 9
Upper Quartile, = 20 (The middle value between 19 and 21)
Highest Value = 30
The box plot for two towns is shown in the diagram below.
Town A box plot is not symmetrical, it's tailing on the left
Town B box plot is not symmetrical, it's tailing on the right

O D. 4
The value of the rational expression when x is equal to 4 is 3.
Option C is the correct answer.
What is an equation?An equation contains one or more terms with variables connected by an equal sign.
Example:
2x + 4y = 9 is an equation.
2x = 8 is an equation.
We have,
To find the value of the rational expression (x + 20)/(x + 4) when x is equal to 4,
We substitute 4 for x in the expression:
(4 + 20)/(4 + 4)
= 24/8
= 3
Therefore,
The value of the rational expression when x is equal to 4 is 3.
