which of the following is equal to 9 • 4?

A.) [tex]\sqrt{9}*\sqrt{4}=3*2=6[/tex]
B.) 18
C.) [tex]\sqrt{\frac{9}{4}}=\frac{3}{2}[/tex]
D.) 36
Your answer is A
The multiplication of 9 • 4 equals 36, which is the result of adding 9 to itself 4 times.
Explanation:The question 'which of the following is equal to 9 • 4?' is asking us to perform a multiplication operation. In Mathematics, when we multiply two numbers, we are essentially adding one of the numbers to itself the number of times indicated by the other number. Therefore, 9 multiplied by 4, which is written as 9 • 4, is equal to adding 9 to itself 4 times: 9 + 9 + 9 + 9.
Let's do the math:
9 + 9 = 1818 + 9 = 2727 + 9 = 36So, 9 • 4 equals 36. This is a basic multiplication concept that is foundational in math.
Blaire needs more than 708 total points on assignments in her math class to pass. She only has 236 points and needs to do some extra credit assignments that are worth 59 points each.
59x + 236 > 708
How many extra credit assignments does Blaire need to complete in order to pass?
A.
x > 236
B.
x > 59
C.
x > 472
D.
x > 8
Answer: D) x = 8
Step-by-step explanation: In order to get this answer, you need to keep the 236 and add 59 evry time until you get 708.
Another thing is to multiply 59 by 8, which will give you 472. Now we add 472 and 236 and we get 708.
59 x 8 = 472 + 236 = 708.
56 + 56 + 56 + 56 + 56 + 56 + 56 + 56 = 472 + 236 = 708.

a milkyway bar is 5 inches long. The bar will be split into two pieces. For each situation find the length in inches of the two pieces and write your answer as the ratio of the larger piece to the smaller piece. Show your work
A) one piece is 1 inch longer than the other?
B) one piece is 60% of the bar
HELPPPPPPPP ASAP
Answer:
A)one is 3 inches and the other is 2 inches.2:5 and 3:5
B)It would be still b three and two because 3/5 of the chocolate bar is 60% and 2/5 is 40%.
Step-by-step explanation:
A) If the bar is 5 inches long and it is broken into two pieces with one that measures an inch longer then you would find that if broken in half it would be 2.5, so if you take the other point 0.5 off of the other 2.5 and add it to the other half then it would have on piece that is an inch longer than the other piece.3+2=5
B) 5(0.6) =3
For Scenario A, the Milky Way bar is divided into two pieces where one piece is 1 inch longer than the other, resulting in lengths of 3 inches and 2 inches, with a ratio of 3:2. In Scenario B, one piece is 60% of the entire bar, equating to 3 inches and 2 inches for the two pieces, again with a ratio of 3:2.
A Milky Way bar is 5 inches long and is split into two pieces.
Scenario A: One Piece Is 1 Inch Longer Than the Other
Let's denote the length of the shorter piece as x. According to the problem, the longer piece would then be x + 1 inch. Since the two pieces together must add up to the total length of the bar, which is 5 inches, we can set up the following equation:
x + (x + 1) = 5 inches
2x + 1 = 5 inches
2x = 5 inches - 1 inch
2x = 4 inches
x = 2 inches
The shorter piece is 2 inches, meaning the longer piece is 2 inches + 1 inch = 3 inches.
The ratio of the longer piece to the shorter piece is therefore 3:2.
Scenario B: One Piece Is 60% of the Bar
In this case, one piece is 60% of 5 inches. We calculate this piece as follows:
60% of 5 inches = 0.60 * 5 inches
= 3 inches
Since one piece is 3 inches, the other piece must be 5 inches minus 3 inches, which is 2 inches. The ratio of the larger piece to the smaller piece is 3:2, the same as in Scenario A.

Write the first five terms of the sequence defined by the explicit formula.
Answer:
(a) 112, 28, 7, (7/4), (7/16)
Step-by-step explanation:
The sequence is given by the explicit formula
[tex]a_{n} = 112 (\frac{1}{4} )^{n-1}[/tex]
The terms of the sequence are :
[tex]a_{1} = 112 (\frac{1}{4} )^{1-1} = 112 (\frac{1}{4} )^{0} =112 [/tex]
[tex]a_{2} = 112 (\frac{1}{4} )^{2-1} = 112(\frac{1}{4} ) =28 [/tex]
[tex]a_{3} = 112 (\frac{1}{4} )^{3-1} = 112(\frac{1}{4} )^{2} = 7 [/tex]
[tex]a_{4} = 112 (\frac{1}{4} )^{4-1}=112(\frac{1}{4} )^{3} = \frac{7}{4}[/tex]
[tex]a_{5} = 112 (\frac{1}{4} )^{5-1}=112 (\frac{1}{4} )^{4} = \frac{7}{16}[/tex]
Allison is rolling her hula hoop on the playground. The radius of her hula hoop is 35 \text{ cm}35 cm. What is the distance the hula hoop rolls in 44 full rotations? Round your answer to the nearest \text{cm}cm.
To find the distance the hula hoop rolls in 4 full rotations, we calculate the circumference as 2πr and then multiply by 4. The total distance is then rounded to the nearest centimeter, resulting in 880 cm.
The question asks us to calculate the distance a hula hoop travels in 4 full rotations given its radius. The distance traveled in one rotation is equal to the circumference of the hoop.
To find the circumference, we use the formula C = 2πr, where r is the radius. Since the radius is given as 35 cm, the circumference is 2π×35 cm. To find the total distance for 4 rotations, we multiply the circumference by 4. This gives us 4×2π×35 cm. Using the approximate value of π (3.1416), we can calculate the distance, and then round it to the nearest centimeter.
Circumference C = 2π×35 cm = 219.91 cm
Total distance for 4 rotations = 4×C = 4×219.91 cm = 879.64 cm
Rounded to the nearest centimeter: 880 cm
As an estimation we are told 5 miles is 8 km.
Convert 34.5 km to miles.
34.5 kilometers is equal to 21.41 miles.
Explanation:To convert kilometers to miles, you can use the conversion factor 1 mile = 1.609 kilometers. So, to convert 34.5 kilometers to miles, you would multiply 34.5 by the conversion factor:
34.5 kilometers × 1 mile/1.609 kilometers = 21.41 miles
Therefore, 34.5 kilometers is equal to 21.41 miles.

Final answer:
The center of a data set can be measured using the mean or the median. In this case, the Rome data center is best described by the mean, while the New York data center is best described by the median.
Explanation:
The center of a data set can be measured using two common ways: the mean and the median. The mean is found by adding up all the values and dividing by the total number of observations. The median is the middle value, or the number that separates the data into two equal halves. It is generally a better measure when there are extreme values or outliers.
In this case, based on the information provided, the Rome data center is best described by the mean, while the New York data center is best described by the median.

the graph of a proportional relationship contains the point 8 and 4 what is the corresponding equation enter your answer as a fraction in simplest form in the box
Answer:
[tex]y=\frac{1}{2}x[/tex].
Step-by-step explanation:
We have been given that the graph of a proportional relationship contains the point 8 and 4.
Since we know that a proportional equation is in form: [tex]y=kx[/tex], where k is constant of proportionality.
Let us substitute x=8 and y=4 in proportional equation to find constant of proportionality for our equation.
[tex]4=k*8[/tex]
Upon dividing both sides of equation by 8 we will get,
[tex]\frac{4}{8}=\frac{k*8}{8}[/tex]
[tex]\frac{4}{8}=k[/tex]
[tex]\frac{1}{2}=k[/tex]
Let us substitute k=1/2 in proportional equation.
[tex]y=\frac{1}{2}x[/tex]
Therefore, our desired equation will be [tex]y=\frac{1}{2}x[/tex].

An isosceles triangle with vertices labeled R, S, and T. Side R T is the base. Sides R S and side S T are equal. Angle R is labeled as 3 x degrees, angle S is labeled as 2 x degrees, and angle T is labeled as 3 x degrees.
Answer:
∠S = 45°
Step-by-step explanation:
As given in the question, ∠R = 3x ; ∠S=2x ; ∠T=3x
So by using angle sum property of a triangle that sum of all the angles of a triangle is 180°.
We get, ∠R+∠S+∠T = 180
[tex]3x+2x+3x=180\\8x=180\\x=\frac{180}{8}[/tex]
So, ∠S=2x
∠S=[tex]2\cdot \frac{180}{8}[/tex]
∠S=45°
Answer:
m∠S= 45°
Step-by-step explanation:
Given an isosceles triangle ABC.
& m∠R = m∠T = 3 x, m∠S = 2 x
The sum of all the angles of triangle is equal to 180°
⇒ m∠R + m∠S + m∠T = 180°
3 x + 2 x + 3 x = 180°
⇒ 8 x = 180°
⇒ x = [tex]\frac{180}{8}[/tex]
⇒ x = [tex]\frac{45}{2}[/tex]
Hence, m∠S = [tex]2\times\frac{45}{2}[/tex]
= 45°

What does The difference of two numbers by 5 look like
Answer:
Step-by-step explanation:
Let the larger number = x
Let the smaller number = y
I can't really tell if I'm reading it correctly, but I think the answer is
x - y = 5
Answer:
Step-by-step explanation:
Suppose you have given two numbers say (x and y ).
Now we can have 3 conditions here:
i . x and y are equal
ii. x is greater than y
iii . y is greater than x .
For x and y are equal : - Difference between two numbers will be zero.
For x and y greater or lesser :- There will be some difference between two numbers x and y. And if this difference between x and y is 5, then it will look like:
x is greater than y
x - y = 5
or
y is greater than x
y - x = 5
