Answer:3^2
Step-by-step explanation:
Find prime numbers that go into nine.
3 goes into to 9 3 times. 3 is a prime number so the prime factorization for nine is
3*3=3^2
The Prime factorization of 9 is expressed as: 3 * 3 or 3²
How to find the prime factors?A prime factor is defined as a natural number, other than 1, whose only factors are 1 and itself. The first few prime numbers are actually 2, 3, 5, 7, 11, and so on.
Now we can also use what's called prime factorization for numbers which actually consist of using factor trees.
Now, some of the factors of 9 are 1, 3, 9. Thus:
Prime factorization of 9 = 3 * 3 = 3²

The line parallel to y=-7x-2 through (-4,6)
The required line parallel to y = - 7x - 2 through (- 4, 6) is y = -7x - 22.
What is slope?The slope is the rate of change of the y-axis with respect to the x-axis.
The equation of a line in slope-intercept form is y = mx + b, where
slope = m and y-intercept = b.
We know the greater the absolute value of a slope is the more steeper is it's graph or rate of change is large.
We know parallel lines have the same slope.
Given line is y = - 7x - 2, hence the required line will also have a slope of - 7
which is passing through the point (-4, 6).
∴ 6 = (-7)(-4) + b.
6 = 28 + b.
b = - 22.
Hence the required line is y = -7x - 22.

Number of Gold medals won by USA are 9 and gold medals won by France are 2.
Let the gold medals won by USA = x
And the gold medals won by France = y
It's given in the question "gold medals won by USA are 1 more than 4 times the number of gold medals won by France"
Therefore, equation for this situation will be,
x = 4y + 1 --------(1)
Second statement of the question states "USA won 7 gold medals more than France"
Therefore, equation will be,
x = y + 7 -------(2)
By substituting the value of 'x' in equation (1) from equation (2),
y + 7 = 4y + 1
4y - y = 7 - 1
3y = 6
y = 2
By substituting the value of 'y' in equation (1),
x = 4(2) + 1
x = 9
Therefore, USA won 9 gold and France won 2 gold medals in the Winter Olympic Games.

What Is the area of a rectangular room that is 3 3/4 yards long and 3 1/3 yards wide
Answer:
[tex]3 \frac{3}{4} \times 3 \frac{1}{3} = \frac{15}{4} \times \frac{10}{3} = \frac{25}{2} = 12 \frac{1}{2} [/tex]
The area of this room is 12 1/2 yd².
The area of the rectangular room is (12.5) square yards, calculated by multiplying length and width.
To find the area of a rectangular room, you multiply its length by its width. Given that the length is [tex]\(3 \frac{3}{4}\)[/tex] yards and the width is [tex]\(3 \frac{1}{3}\)[/tex] yards, you can calculate:
[tex]\[ \text{Area} = \text{Length} \times \text{Width} \][/tex]
First, let's convert the mixed numbers to improper fractions:
[tex]\[ 3 \frac{3}{4} = \frac{4 \times 3 + 3}{4} = \frac{12 + 3}{4} = \frac{15}{4} \text{ yards} \]\[ 3 \frac{1}{3} = \frac{3 \times 3 + 1}{3} = \frac{9 + 1}{3} = \frac{10}{3} \text{ yards} \][/tex]
Now, plug these values into the formula:
[tex]\[ \text{Area} = \frac{15}{4} \times \frac{10}{3} \]\[ \text{Area} = \frac{15 \times 10}{4 \times 3} \]\[ \text{Area} = \frac{150}{12} \]\[ \text{Area} = 12.5 \text{ square yards} \][/tex]
So, the area of the rectangular room is [tex]\(12.5 \, \text{square yards}\).[/tex]

- Varun drove to work this morning. It took
him 15 minutes. He stopped at a traffic
light for 3 minutes after driving for
5 minutes. Sketch a graph to represent
the distance from Varun's house during
his drive to work.
Answer:
See attached graph
Step-by-step explanation:
The graph of distance from home as a function of time starts at the origin of coordinates (0,0) since at time zero minutes Varun is at home.
Then we represent his driving at constant speed (although it has not been specified in the problem) as a line with positive slope equal to his speed, that goes on for the first five minutes. After that, he reaches the traffic light that keeps him at the same distance from home for three minutes (notice the line representing the distance covered is flat from minute 5 to minute 8, while he is not moving).
Then he starts moving again (we assume at the same speed as before - so the line representing his position is again a line with positive slope and with the SAME inclination as that which represents the first 5 minutes of his trip.
The line ends at minute 15 which is the time it took him to get to work.
A container of oregano is 17 pounds heavier than a container of peppercorns. Their total weight is 253 pounds. The peppercorns will be sold in one-ounce bags. How many bags of peppercorns can be made?
Answer:
1,888 bags.
Step-by-step explanation:
Let x represent the the weight of container of peppercorns.
We have been given that the container of oregano is 17 pounds heavier than a container of peppercorns. So the weight of container of oregano would be [tex]x+17[/tex].
We are also told that the total weight of both containers is 253 pounds. We can represent this information in an equation as:
[tex]x+x+17=253[/tex]
Let us solve for x.
[tex]2x+17=253[/tex]
[tex]2x+17-17=253-17[/tex]
[tex]2x=236[/tex]
[tex]\frac{2x}{2}=\frac{236}{2}[/tex]
[tex]x=118[/tex]
Therefore, the weight of peppercorns is 118 pounds.
Now, we will convert 118 pounds to ounces.
1 pound equals 16 ounces.
118 pounds = 118*16 ounces = 1,888 ounces
Since the peppercorns will be sold in one-ounce bags, therefore, 1,888 bags of peppercorns can be made.

What is a whole number
Answer:
Whole numbers are positive numbers (this includes 0) that do not have decimals or fractions to them.
Example:
1, 2, 3, 4, 5,etc are all whole numbers, because they are positive and do not have decimals or fractions
1.25 would not be a whole number, because although it is positive, it has a decimal.
The formula
h
=
v
t
−
16
t
2
gives the height
h
, in feet, of an object projected into the air with an initial vertical velocity
v
, in feet per second, after
t
seconds.
If an object is projected upward with an initial velocity of
80
feet per second, at what times will it reach a height of
96
feet above the ground?
It'll be at
96
feet above the ground at
and
seconds
Answer:
t=6
Step-by-step explanation:
We are solving for [tex]t[/tex]. To do this, let's fill in the known variables.
[tex]h=vt-16t^2[/tex]
[tex]v=80\\h=96[/tex]
[tex]96=80t-16t^2[/tex]
[tex]16t^2-80t+96=0\\16(t^2-5t+6)=0[/tex]
Since the product must equal 0, that means that the factor in the parentheses hasto be equal to 0. Therefore,
[tex]t^2-5t+6=0\\(t+1)(t-6)=0\\\\t+1=0 OR t-6=0\\t=-1 OR t=6[/tex]
However, since the time cannot be negative, [tex]t=-1[/tex] cannot be a valid answer.
Therefore, the only valid time is t=6.
I hope this helps.
Let's start with the projectile motion formula which is h = vt - 16t².
In this formula, h is the height of the object,
v is the initial velocity, and t is the time.
We know that the initial velocity is 80 feet per second
so we can plug an 80 in for v in our formula.
We also know that the object reaches a height of 96 feet above the
ground which means we can plug an 96 in for h in our formula.
So we have 96 = 88t - 16t².
To solve this equation, we set it equal to 0 by subtracting
88t and adding 16t² to get 16t² - 88t + 96 = 0².
Now we can divide both sides by 8 to get 2t² - 11t + 12 = 0.
Now we can factor the left side to get (2t - 3)(t - 4) = 0.
So this means that 2t - 3 = 0 or t - 4 = 0.
So t = 3/2 or t = 4.
Now, the reason there are two answer is because the object will be
96 feet off the ground on its way up and on its way down.
standard form
4x-8=9y-5
Answer:
4x - 9y = 3
Step-by-step explanation:
The equation of a line in standard form is
Ax + By = C ( A is a positive integer and B, C are integers )
Given
4x - 8 = 9y - 5 ( subtract 9y from both sides )
4x - 9y - 8 = - 5 ( add 8 to both sides )
4x - 9y = 3 ← in standard form
The original equation 4x - 8 = 9y - 5 can be rearranged to the standard form by initially adding 8 to both sides and then subtracting 9y from both sides. The final equation in standard form is 4x - 9y = 3.
Explanation:The given equation is in the form of 4x - 8 = 9y - 5. To convert the equation to standard form, we'll need to rearrange it so all variables and constants are on one side of the equation. Standard form is typically written as Ax + By = C. Here are the steps to do that:
Add 8 to both sides: 4x = 9y - 5 + 8 (which simplifies to 4x = 9y + 3)Subtract 9y from both sides: 4x - 9y = 3So, the
standard form
of the given equation is 4x - 9y = 3.

Step-by-step explanation:
9+8x>-24
1) Subtract 9 from both sides:
8x>-33
2) Divide both sides by 8:
x>-33/8
The algebraic representation of the problem is 9 + 8x > -24. After isolating 'x', the solution to the inequality is x > -4.125, which means any number greater than -4.125 satisfies the equation.
Explanation:The problem presented is a linear inequality, a topic of mathematics. The sentence 'Nine increased by the product of a number and 8 is greater than -24' can be represented algebraically as 9+8x > -24, where 'x' is the number in question.
To solve it, as we aim to find the value for 'x', you first isolate 'x' on one side of the inequality. Start by subtracting 9 from both sides to get 8x > -24 - 9, which results in 8x > -33. Then, you divide both sides by 8 to solve for 'x'. As a result, x > -33/8, or x > -4.125.
This means that any number greater than -4.125 will satisfy the equation 'Nine increased by the product of a number and 8 is greater than -24'. So, the solution to this inequality is x > -4.125.

8. The art department at a school sold 323 tickets
to an art show, for a total of $790. Students paid
$2 for tickets, and non-students paid $3.50. The
principal asked how many non-students
attended the art show.
a) Write a system of two linear equations
for this situation.
b) Solve the problem by graphing the system.
Answer:
Step-by-step explanation:
students = x
non-students=y
x+y=410
y=410-x
3x+7y=1650
3x+7(410-x)=1650
3x+2870-7x=1650
-4x=-1220 (divide both sides by -4)
x=305 y=410-305=105
Hence, 305 students attended and 105 non-students attended
The problem can be represented by two linear equations, s + n = 323 and 2s + 3.5n = 790. After putting these equations into the format y = mx + b, they can be graphed to find the solution at the point where the two lines intersect.
Explanation:First, let's define two variables, s for the number of students and n for the number of non-students. From the information we have:
Students and non-students combined bought a total of 323 tickets, so our first equation is: s + n = 323.Students paid $2 and non-students paid $3.50, making a total of $790. This gives our second equation: 2s + 3.5n = 790.To solve the problem by graphing, we need to convert these equations into y = mx + b format. Our first equation then becomes s = -n + 323 and the second becomes s = (790 - 3.5n) / 2. Plotting these equations on a graph and finding the point where the lines intersect will give us the value of s and n. The x-values corresponds to n (non-students) and y-values to s (students).

Explanation:
The expression that is equivalent to 4,325,000,000 is 4.325 × 109.
When we write a number in scientific notation, we express it as a product of a coefficient and a power of 10. In this case, the coefficient is 4.325 and the power of 10 is 9. This means that we move the decimal point 9 places to the right, resulting in a value of 4,325,000,000.
So the correct expression is 4.325 × 109.
