x<2.1 is the simplified inequality.
What is an inequality?An inequality is an inequation separated by <,>≥,≤. In Mathematics, the relationship between two values that are not equal is defined by inequalities. Inequality means not equal. Generally, if two values are not equal, we use “not equal symbol (≠)”
Given here: The inequality -4x>8.4
multiplying by -1/4 both sides we get
4x/4 < -8.4/4
x<-2.1
Hence, x<2.1 is the simplified inequality.

The circumference of a circle is 44 cm. Find its area (use π = 22/7)
Answers
Answer:
We know that the formula for the circumference of a circle is given by:
C = 2πr
where C is the circumference and r is the radius of the circle.
In this case, we are given that the circumference is 44 cm. Substituting this value, we get:
44 = 2πr
Using π = 22/7, we can solve for the radius:
44 = 2(22/7)r
Multiplying both sides by 7/44, we get:
r = 7/2
Now that we know the radius of the circle is 7/2 cm, we can use the formula for the area of a circle:
A = πr^2
Substituting the value of r, we get:
A = (22/7) * (7/2)^2
Simplifying, we get:
A = (22/7) * 49/4
A = 385/28 square cm
Therefore, the area of the circle is 385/28 square cm.
Answer:
154 cm²
Step-by-step explanation:
We know that, the formula to find the circumference of a circle is:
C = 2 π r
Here,
C = circumference ⇒ 44 cm
r = radius
First, let us find the value of r.
\(\sf C = 2\pi r\\\\44 = 2 *\frac{22}{7}*r\\\\44 =\frac{44r}{7}\\\\44*7=44r\\\\\frac{44*7}{44} =r\\\\7\:cm=r\)
Let us find the area of the circle.
The formula to find the area of a circle is:
A = π r²
\(\sf Let\:us\:find\:it\:now.\\\\A = \pi r^2\\\\A=\frac{22}{7} *7*7\\\\A =\frac{1078}{7}\\\\A= 154cm^2\)

Answers
Answer:
\(a= - 3 \\ b = 6\)
Answer:
a=-3, b=6
Step-by-step explanation:
1) First, take a=1/2b-6 and plug it into 2a+3b=12
2(1/2b-6)+3b=12
2) Multiply out the 2
b-12+3b=12
3) Combine like terms
4b-12=12
4) Isolate b by adding 12 to the other side
4b=24
5) Divide by 4 so b doesn't have a variable in front
b=6
To solve for a:
You know that b=6, and a=1/2b-6 so you can plug in b to solve for a
a=1/2(6)-6
Solve the equation to get a
a=3-6
a=-3

A basket contains only apples and oranges, and the ratio of apples to oranges is 9:7. If there are 128 pieces of fruit in he basket, how many are oranges?
Answers
Answer:
There are 56 oranges in the basket, since the ratio of apples to oranges is 9:7. To calculate this, you can use the proportion method. First, set up a proportion using the ratio of apples to oranges (9:7):
9/7 = x/128
Then, solve for x.
x = (9/7) * 128
x = 112
Answer:
72 and 56
Step-by-step explanation:
Ratio of apples in the basket = 9x
Ratio of oranges in the basket = 7x
Total fruits in the basket = 128
So, Apples + Oranges = Total fruit
9x + 7x = 128
16x = 128
x = 128 ÷ 16
x = 8
∴ So, number of apples = 9x --> 9*8 = 72 apples
number of oranges = 7x --> 7*8 = 56 oranges

First we start with the formula for cylinders v=(pi)r(squared)h filled in Thats v=(3.14)(8 squared) (8) which brings us to the answer 1607.68 but you must round to the nearest tenth aka 1607.7
Answer:
The first option, V ≈ 1607.7 in²
Step-by-step explanation:
Find the volume of the given cylinder.
\(\begin{center}\framebox{\parbox{4cm}{\textbf{Volume of a Cylinder:}\\[2ex]The volume of a cylinder with radius $r$ and height $h$ is given by the formula:\\[2ex]\center{$V = \pi r^2 h$} \\ \\}}\end{center}\)
Given:
r = 8 in
h = 8 in
π = 3.14
Find:
V = ?? in³
\(\hrulefill\)
Now solving,
Substitute the given values into the formula:
=> V = (3.14)(8)²(8)
Using a calculator to simplify:
=> V = 1607.68 in²
Rounded to the nearest tenth:
∴ V ≈ 1607.7 in²
Thus, the first option is correct.

In a box plot, also known as a box-and-whisker plot, the data is dispersed and represented visually to provide a summary of the distribution and key characteristics of the dataset. Let's describe how the data is dispersed in the box plot for the given data set: 25, 36, 21, 30, 20, 32, 38, 19, 36, 31, 26, 33, 27, 18, 24.
1. Median (Q2): The median represents the middle value of the dataset when arranged in ascending order. In this case, the median is around 27 or 28, as it lies between the values 27 and 30.2. Lower Quartile (Q1): The lower quartile marks the boundary between the lower 25% of the data and the upper 75%. It is located approximately around 22 or 23, as it falls between the values 21 and 24.3. Upper Quartile (Q3): The upper quartile marks the boundary between the lower 75% of the data and the upper 25%. It is located around 34 or 35, as it lies between the values 33 and 36.4. Interquartile Range (IQR): The IQR is the range between the upper and lower quartiles (Q3 - Q1). In this case, the IQR is approximately 12 (35 - 23).5. Whiskers: The whiskers represent the range of the data excluding any outliers. They extend from the lower quartile (Q1) to the minimum value and from the upper quartile (Q3) to the maximum value. However, in some cases, the whiskers can also be defined based on certain criteria, such as 1.5 times the IQR. Outliers, if present, are depicted as individual data points beyond the whiskers.6. Outliers: Outliers are data points that significantly deviate from the rest of the dataset. In this case, there are no clear outliers based on the data provided.7. Box: The box in the box plot spans from the lower quartile (Q1) to the upper quartile (Q3) and represents the middle 50% of the data. In this case, the box spans approximately from 23 to 35.By observing the box plot, we can see that the data is moderately dispersed, with the majority of values concentrated around the median. The range of the data is approximately 20 to 38, with some variability within the dataset.

Minimum value: 18
First quartile (Q1): 22
Median: 29
Third quartile (Q3): 36
Maximum value: 38
The box plot is created using these values. A box is drawn from Q1 to Q3 with a line inside the box at the median. Whiskers are drawn from the box to the minimum and maximum values. Any data points beyond the whiskers are plotted as individual points.
In this box plot, the data is dispersed fairly evenly, with no outliers beyond the whiskers. The box is centered around the median, indicating that the data is roughly symmetric. The lower half of the data is slightly more spread out than the upper half, as indicated by the longer whisker on the left side of the box. Overall, the box plot shows that the data is relatively consistent, with no extreme values.

Mr. Weaver invested part of his $6000 inheritance in an account that earns 4%
simple interest and the other part in an account that earns 7% simple interest.
How much did he invest in each account if the two accounts earned $360 after
the first year?
Answers
Answer:
Mr. Weaver invested $ 2,000 in the 4% simple interest account and $ 4,000 in the 7% simple interest account.
Step-by-step explanation:
1. Let's review the information given to us to answer the question correctly:
Amount of the inheritance = $ 6,000
Interest rate of the first part = 4% simple
Interest rate of the second part = 7% simple
Interest of the accounts after the first year = $ 360
2. How much did he invest in each account?
For answering the question, we will use the following equation:
x = Amount invested in the first account
6,000 - x = Amount invested in the second account
0.04x + 0.07 * (6,000 - x) = 360
0.04x + 420 - 0.07x = 360
-0.03x = 360 - 420 (Subtracting 420 at both sides)
-0.03x = -60
x = -60/-0.03
x = 2,000 ⇒ 6,000 - x = 4,000
Mr. Weaver invested $ 2,000 in the 4% simple interest account and $ 4,000 in the 7% simple interest account.
