explain how I get 1.2 from multiplying 4×0.3
To multiply 4x0.3 you need to multiply as if there is no decimal, 4x3=12
Then you count the number of digits after the decimal and put the same number of digits behind the decimal in the product.
Because 0.3 has just one number behind the decimal and there is only 1 number after the decimal it would be 1.2
A Chick-o-stick is the inside of a Butterfingermade into a cylinder. A Chick-o-stick has adiameter of 1.8 cm and a height of 9.6 cm, ifwe were to cover it in chocolate, how mucharea needs to be covered?
It is given that the diameter is 1.8 cm so the radius is 0.9 cm
It is also given that the height is 9.6 cm.
It needs to be covered in chocolate so the surface area of the cylinder needs to be calculated.
The surface area of the cylinder is given by:
[tex]A=2\pi\times r(r+h)[/tex]Substitute the values to get:
[tex]\begin{gathered} A=2\times\pi\times0.9(0.9+9.6) \\ A=59.3761cm^2 \end{gathered}[/tex]Hence the area of chocolate required is 59.3761 square centimeters.

What are mathematics operations?
• An operation is a function in mathematics that converts zero or more input values (also known as "operands" or "arguments") to a well-defined output value.
• The operation's arity is determined by the number of operands.
• Binary operations (i.e., operations of arity 2), such as addition and multiplication, and unary operations (i.e., operations of arity 1), such as additive inverse and multiplicative inverse, are the most commonly studied operations.
• A zero-arity operation, also known as a nullary operation, is a constant.
• The mixed product is an example of an arity 3 operation, also known as a ternary operation.
We have,
Adventurers swing set wholesale selling price = $3056
Markup means the amount increased.
20% Mark up on the price:
= 20% of 3056
= 20/100 x 3056
= $611.2
The selling price of Adventurers swing set:
= $3056 + $611.2
= $3,667.2
Rounding to the nearest cent:
= $3,667
Thus the selling price of Adventurers swing set is $3,667

in the figure, M angle 7 =100, find the measure of angle 6?how would I solve this?
The angle 6 has its measure to be 80 degrees
How to determine the measure of angle 6?The figure represents the given parameter
Also from the question, we have the following parameters that can be used in our computation:
m∠angle 7 = 100 degrees
The angles 7 and 6 are angles on the same straight line
As a general rule of angles, angles on the same straight line add up to 180 degrees
This means that
m∠angle 7 + m∠angle 6 = 180
Substitute the known values in the above equation
So, we have the following equation
100 + m∠angle 6 = 180
Subtract 100 from both sides
So, we have the following equation
- 100 + 100 + m∠angle 6 = 180 - 100
Evaluate the like terms in the above equation
m∠angle 6 = 180 - 100
Evaluate the like terms in the above equation
m∠angle 6 = 80
Hence, the measure of angle 6 is 80 degrees

MODELING REAL LIFE A public university charged $9500 for tuition and fees in the 2015–2016 academic year. This cost increased at a constant rate and reached $10,500 in the 2020–2021 academic year. Estimate the cost of tuition and fees in the 2024–2025 academic year. The cost of tuition and fees in the 2024–2025 academic year is about $\$$ .
The cost of tuition and fees in the 2024–2025 academic year is about the amount of $11,300.
What is the Linear equation?A linear equation is defined as an equation in which the highest power of the variable is always one.
As per the given information, take two points as
(9500, 0)
(10,500, 5)
Here 2015–2016 academic year is represented as zero
So the linear equation model would be
y - 9500 = [(10,500 - 9500) / (5-0) ](x - 0)
y - 9500 = (1000/5)x
y = 200x + 9500
So the cost of tuition and fees in the 2024–2025 academic year:
Here 2024–2025 academic year is represented as nine,
Substitute the value of x = 9 in the linear equation model y = 200x + 9500
y = 200(9) + 9500
y = 1800 + 9500
y = 11,300
Thus, the cost of tuition and fees in the 2024–2025 academic year is about $11,300.

Answer:
x = 8
AB = 1
BC = 1
Step-by-step explanation:
AB = BC when
[tex]\dfrac{3}{4}x - 5 = \dfrac{9}{4}x - 17[/tex]
In the above equation bring all the x terms to the left and the constants to the right as follows
Add 5 on both sides:Since x = 8 we can solve for the lengths of both segments by plugging in the value in the two expressions
[tex]AB = \dfrac{3}{4} \times 8 - 5\\\\AB = 6 - 5 = 1\\\\BC = \dfrac{9}{4} \times 8 - 17\\\\BC = 18 - 17 = 1\\\\[/tex]
So AB = BC = 1
Answer:
x = 8 , AB = BC = 1
Step-by-step explanation:
we require
AB = BC , that is
[tex]\frac{3}{4}[/tex] x - 5 = [tex]\frac{9}{4}[/tex] x - 17
multiply through by 4 to clear the fractions
3x - 20 = 9x - 68 ( subtract 9x from both sides )
- 6x - 20 = - 68 ( add 20 to both sides )
- 6x = - 48 ( divide both sides by - 6 )
x = 8
Then
AB = [tex]\frac{3}{4}[/tex] × 8 - 5 = 6 - 5 = 1
BC = [tex]\frac{9}{4}[/tex] × 8 - 17 = 18 - 17 = 1
so AB = BC

If the heads never comes up 2 times in a row, he will quit. What is the probability that Mr. Campbell will decline signing the business contract? A. 1/2 B. 1/4 C. 3/8 D. 7/16
Given:
Mr. Campbell will flip a fair coin 4 times.
So, the total results = 2⁴ = 16
We will find the probability of heads coming up 2 times in a row:
We will use the tree method to find the number of heads coming up 2 times in a row, Let head (H) and tail (T)
So, the tree figure will be as shown in the following figure:
As we can see the red ellipses is the number of time comes 2 heads in a row
The number = 7
so, the probability that Mr. Campbell will decline signing the business contract = 7/16
The answer will be option D. 7/16

Boone High School is holding a fundraiser and plans to use 2/3 of the money collected to build a new library of the money directed towards building the new library 3/4 will go towards purchase and computers what fraction of the money raised will go towards purchasing computers for the library
Given that Boone High School is holding a fundraiser and plans to use:
• 2/3 of the money collected to build a new library.
,• of the money directed towards building the new library, 3/4 will go towards purchase and computers.
,• We want to know what fraction of the money raised will go towards purchasing computers for the library.
In other words, we want to know what 3/4 of 2/3 is.
Let x be 4/3 of 2/3
Then
[tex]\begin{gathered} x\text{ = }\frac{4}{3}\text{ }\times\frac{2}{3} \\ =\text{ }\frac{8}{9} \end{gathered}[/tex]Therefore, the fraction of the money raised will go towards purchasing computers for the library is 8/9
in a park, the ratio of adults to children is 9 to 3. If there are 216 people in the park, how many children are there?
Answer:
if the question specifically says people then the amount of children are 54.
if the question specifically says the amount of adults in the park compared to the children when there are 216 adults, then the answer is 72.
Step-by-step explanation:
children and adults
so we know that this is a scale factor question because there is a ratio involved . the ratio is 9 to 3 . so the next ratio answer is 216 to what ?
how do you get from 9 to 216 ? the answer is that you multiply by 216 / 9 . this is a form of math short hand if you did not know already . to get from y to x, you multiply y by x/y.
so basically that means that you multiply 9 by 216 / 9 to get to 216 . that means that the scale factor is 216 / 9 . so you will want to multiply three by 216 / 9 because 216 / 9 is the scale factor .
216 / 9 is equal to 24 . now multiplying the scale factor by 3 is equal to 72 . therefore there are 72 children compared to 216 adults.
_____
children and people
if the question is asking specifically people not adults then instead you will want to add nine with three to get the total amount of people . 9 + 3 = 12 so the new ratio will be 12 people to three children . so with the same idea in mind 12 to 3 and 216 to what? to get from 12 to 216 you need to multiply by 216 / 12 thus 216 / 12 is the scale factor in this situation. 216 / 12 = 18 so the scale factor here is 18 so you need to multiply 18 by 3 to get the total amount of children there compared to the total amount of people . the total amount of children there are 54 .
