Answer:
x+y=28
70x+140y=3360
8 cats, 20 dogs were sold
Step-by-step explanation:
Let x=cats y=dogs
We know that a total of 28 pets were sold which means that
x+y=28
We also know that they made 3360 which means that
70x+140y=3360
It doesn't really say if you need to solve this but I will anyways
We use the first equation (x+y=28) and subtract 28 and y from both sides to get
x-28= -y we can then divide both sides by -1 so y can be a positive
-x+28=y
This is what y equals in terms of x and so we can plug this in for y in the second equation
70x+140(-x+28)=3360
Distribute the 140 and get
70x-140x+3920=3360
Add like terms and subtract 3920 to get
-70x=-560
divide both sides by -70 and get
x=8
We now know that 8 cats were sold and can plug this value into any equation to solve for y ( I will be using the first one because that's easiest)
8+y=28
subtract 8 and get
y=20
A system of equations that matches the situation is:
1) d + c = 28.................Equation 1
2)140d + 70c = 3360............Equation 2
This question has to do with Algebraic equations.
Let's represent
Number of dogs = d
Number of cats = c
A pet store is selling dogs for $140 and cats for $70. If 28 pets were sold and they made $3,360.
We have two algebraic systems of equations for the above statements
1) d + c = 28.................Equation 1
2) $140 x d + $70 x c = $3,360
140d + 70c = 3360............Equation 2

Reggie wanted to compare his grades with the national averages. Which measure of central tendency would be the best for Reggie to use? A. the mean B. the median C. the range D. none of these measures
Answer:
D
Step-by-step explanation:
The mean is usually the best measure of central tendency to use when your data distribution is continuous and symmetrical, such as when your data is normally distributed.
Option (A)
Which measure of central tendency would be to compare?
Typically the trimean and trimmed mean will fall between the median and the mean, although in this case, the trimmed mean is slightly lower than the median. The geomtric mean is the lower than all measures except the mode. Measures of central tendency for the test scores.

Answer:
y=20x+25, this equation is linear, the rate of change is constant
Step-by-step explanation:
She starts with 25$, that doesn't change so its our constant. Let x represent each week. Each week she ears 20$
So, let y represent the total amount of money she has
y=20x+25, this equation is linear, the rate of change is constant

Choose the division equation that represents the fraction shown.
one fourteenth = ________
A) 1 ÷ 14 = ________
B) 14 ÷ 11 = ________
C) 13 ÷ 14 = ________
D) 14 ÷ 13 = ________
Answer:
your answer is gonna be "A" if you want to type 1/14 into the calculator.
The value of expression one fourteenth = A) 1 ÷ 14
How can we interpret the division?When 'a' is divided by 'b', then the result we get from the division is the part of 'a' that each one of 'b' items will get. Division can be interpreted as equally dividing the number that is being divided into total x parts, where x is the number of parts the given number is divided.
We need to find the expression of one fourteenth
A negative divided by a negative is positive, then;
one fourteenth = 1/14
Or
1 ÷ 14
Therefore, The value of 1 ÷ 14 = 1/14.

What happens to a sphere if you double the length of its radius? Check all that apply.
The sphere gets bigger.
The sphere gets smaller.
The diameter doubles.
The diameter quadruples.
The surface area doubles.
The surface area quadruples.
Answer:
The right answers are: The sphere gets bigger/The diameter doubles/The surface area quadruples.
Step-by-step explanation:
From Geometry, we remember that surface area and volume of the sphere are represented by:
[tex]A_{s} = 4\pi\cdot r^{2}[/tex] (1)
[tex]V = \frac{4\pi}{3}\cdot r^{3}[/tex] (2)
Where [tex]r[/tex] is the radius of the sphere. The diameter is two times the radius of the sphere.
If the radius of the sphere is doubled, then the sphere gets bigger, the diameter is double, the surface area is doubled and the volume is octupled. Therefore, the right answers are: The sphere gets bigger/The diameter doubles/The surface area quadruples.
Answer:
The sphere gets bigger , the diameter doubles, the surface area quadruples

List the negative integers with absolute value less than 5
Step-by-step explanation:
absolute value (or modulus) | x | of a real number x is the non-negative value of x without regard to its sign. For example, the absolute value of 5 is 5, and the absolute value of −5 is also 5. The absolute value of a number may be thought of as its distance from zero along real number

The guidance office at a high school surveyed their 12th grade students to know in which of four states they would prefer to live in after highschool. The results are summarized in the tso way frequency table below.
Which two-way table accurately represents the relative frequency for the whole table in this situation?
Hence, the two way frequency table is:
Action Drama Comedy total
Highschool 26/128=0.20 14/128=0.11 22/128=0.17 0.48
College 20/128=0.16 28/128=0.22 18/128=0.14 0.52
----------------------------------------------------------------------------------------------------------
total 0.36 0.33 0.31 1
Step-by-step explanation:
" When a two-way table displays percentages or ratios (called relative frequencies), instead of just frequency counts, the table is referred to as a two-way relative frequency table " .
We are given a table or data as:
Action Drama Comedy Total
Highschool 26 14 22 62
College 20 28 18 68
------------------------------------------------------------------------------------------------------------
Total 46 42 40 128
The total number of students in all the categories and classes are: 128
Hence the two way frequency table is constructed by dividing all the frequencies by the total number of students i.e. 128.
Action Drama Comedy total
High school 26/128=0.20 14/128=0.11 22/128=0.17 0.48
