I'm thinking of two number,12 and another number.12 and my other number have a greatest common factor of 6 and their least common multiple is 36 .What's the other number I'm thinking of
Answer:
18
Step-by-step explanation:
Normally, when you multiply two numbers, their product equal to the product of their greatest common factor and their least common multiple
Let the number be y
The product of 12 and y is 12 y
Also, the product of their greatest common factor and their least common multiple is 6*36=216
Now
12y=216
Divide both sides by 12 to obtain y as
Y=216/12=18
Therefore, the other number is 18.
To prove
Factors of
12=2*2*3
18=2*3*3
Common factors for both are 2*3=6 equal to given GCD
The multiplies are 2*2*3*3=36
A cable running from the top of a utility pole to the ground exerts a horizontal pull of
800 Newtons and a vertical pull of 800V3 Newtons. What is the sine of the angle o
between the cable and the ground? What is the measure of this angle?
Answer:
a. (√3)/2
b. 60 degrees.
Step-by-step explanation:
Please kindly check the attached files for explanation.
The sine of the angle is √3 / 2, and the measure of the angle is 60°.
Finding the Angle Between a Cable and the Ground
To determine the sine of the angle ( heta) between the cable and the ground, we need to use the horizontal and vertical forces exerted by the cable. We have a horizontal pull of 800 Newtons and a vertical pull of 800√3 Newtons.
First, we calculate the sine of the angle using the formula:
Sine ( heta) = Opposite / Hypotenuse
Here,
Opposite = Vertical Pull = 800√3 N
Hypotenuse = Resultant Force = √[(Horizontal Pull)^2 + (Vertical Pull)^2] = √[(800)^2 + (800√3)^2] = 1600 N
Thus,
Sine ( heta) = 800√3 / 1600 = √3 / 2
We know that the angle heta with a sine value of √3 / 2 is 60 degrees (or heta = 60°).
In conclusion, sine of the angle is √3 / 2, and the measure of the angle is 60°.

I need the coordinates for these
3x-2y=2
5x=5y+10
Answer:
solution is (-2, -4)
Step-by-step explanation:
I assume you want the solution?
so we want to find the intersection.
3x - 2y = 2
5x = 5y + 10
simplify the last equation
x = y + 2 by dividing out the 5
substitute
3*(y + 2) - 2y = 2
3y + 6 - 2y = 2
y + 6 = 2
y = -4
x = -4 + 2 = -2
solution is (-2, -4)
The yearly income I, in dollars, for the dairy comes from milk production, which depends on the number C of dairy cows. Each dairy cow produces 3500 gallons of milk per year, and the dairy sells milk for 2.00 per gallon. Find a formula that gives I as a linear function of C
Answer:
[tex]I=7000C[/tex]
Step-by-step explanation:
Let C represent number of dairy cows.
We have been given that each dairy cow produces 3500 gallons of milk per year. So amount of milk produced by C cows in 1 year would be [tex]3500C[/tex] gallons.
We are also told that the dairy sells milk for 2.00 per gallon. So yearly income I, in dollars for the dairy milk production would be 2.00 times the yearly milk production.
Since yearly milk production from C cows is [tex]3500C[/tex], so Income would be:
[tex]I=2.00(3500C)[/tex]
[tex]I=7000C[/tex]
Therefore, the formula [tex]I=7000C[/tex] represents yearly income (I) as a linear function of C.

thank you!
Answer:
a) no
Step-by-step explanation:
-The diagrams can be said to be mathematically similar if the dimensions of their corresponding sides enlarge or reduce by the same factor.
-We therefore determine the enlargement factor for both the radius and height as below:
-Let k be the scale factor
[tex]k_r=\frac{R}{r}\\\\=\frac{3.64}{2.6}\\\\=1.4\\\\k_h=\frac{H}{h}\\\\=\frac{10.192}{8.32}\\\\=1.225\\\\k_r\neq k_h[/tex]
Hence, the cylinders are not mathematically similar since the enlargment factors for the radius and height are not equal.

Question:
Francisco is playing a game with 3 green, 2 yellow, 4 red, and 3 black marbles in a bag. He has calculated the probability of drawing a yellow marble, not replacing it, and then drawing a red marble. Explain the error in his solution.
The Probability is (2/12)(4/12) = 8/144
Answer:
P = (2/12)(4/11) = 2/33
Step-by-step explanation:
There are total 3 + 2 + 4 + 3 = 12 marbles
The probability of drawing a yellow marble is given by
P(yellow) = number of yellow marbles/total number of marbles
There are 2 yellow marbles and total 12 marbles
P(yellow) = 2/12
Then Francisco draws a red marble without replacing the first one so that means there are total 11 marbles left.
P(red) = number of red marbles/total number of marbles
There are 4 red marbles and total 11 marbles
P(red) = 4/11
Therefore, the overall probability is
P = (2/12)(4/11) = 2/33
Francisco made the error of calculating the probability with replacement whereas, in reality he did not replaced the marble after drawing the yellow marble, so he should have used total 11 marbles for the calculation of drawing red marble,
To write 11x2+17x−10 in factored form, Diego first listed pairs of factors of -10. (_+5)(_+-2) (_+2)(_+-5) (_+10)(_+-1) (_+1)(_+-10) Use what Diego started to complete the rewriting. Only one of the factored forms needs to be used and completed.
Answer:
The factored form of the polynomial is 11*(x+2)*(x-5/11). The root found was r = -2
Step-by-step explanation:
If you take a positive value of x, you will most likely obtain positive results, since 11x² + 17x ≥ 11 + 17 = 28 for x ≥1, which means that 11x²+17x-10 ≥ 28-10 = 18 > 0.
Therefore, we prove with negative values.
x = -1: 11*(-1)²+17*(-1) - 10 = -16x = -2: 11*(-2)² + 17*(-2) - 10 = 44-34-10 = 0Therefore, -2 is a root. We can find the other knowing that
p(x) = 11*(x-r₁)*(x-r₂) = 11*(x-(-2)) * (x-r₂) = 11*(x+2)*(x-r₂)
The independent term is 11*2*(-r₂) = -22r₂ = -10
thus, r₂ = -10/-22 = 5/11.
Therefore, p(x) = 11*(x+2)*(x-5/11)
To write 11x2+17x−10 in factored form we find two numbers whose sum is 17 and product is -110. The correct pair is 2 and -55 which leads to the factored form (11x - 55)(x + 2).
Explanation:The question involves factoring a quadratic expression, 11x2+17x−10. To re-write this expression in factored form, one needs to find two numbers, such that their sum equals to the coefficient of x, 17, and their product equals to the product of the coefficient of x² and the constant term (11*(-10)=-110). Diego started by listing all pairs of factors of the constant term, -10. The correct pair here, considering the product and the sum, are 2 and -55, because 2*(-55)=-110 and 2+(-55)=17. Therefore, our factored form will be: (11x - 55)(x + 2).

Alice Jones worked 32 hours this week. She paid $4.00 per hour. She also earned $250 in tips. What is Alices gross pay for this week?
Answer:378
Step-by-step explanation:32 times 4=178 +250=378
Alice Jones's gross pay for the week is the sum of her hourly earnings ($128 from working 32 hours at $4.00 per hour) and her tips ($250), totalling $378.
To calculate Alice Jones's gross pay, we need to consider both her hourly wage and her tips. Alice worked 32 hours this week and was paid $4.00 per hour. This means her earnings from her hourly wage are:
32 hours times $4.00/hour = $128
Alice also earned $250 in tips. To find her gross pay for the week, we add her hourly earnings to her tips:
$128 + $250 = $378
Therefore, Alice's gross pay for the week is $378.

Gavin is a sandwich maker at a local deli. Last week, he tracked the number of peanut butter and jelly sandwiches ordered, noting the flavor of jelly and type of peanut butter requested.
The probability that a sandwich was made with raspberry jelly is 0.84, the probability that it was made with creamy peanut butter is 0.27, and the probability that it was made with raspberry jelly and creamy peanut butter is 0.19.
What is the probability that a randomly chosen sandwich was made with raspberry jelly or creamy peanut butter?
Answer:
P(A∪B) = 0.92
Step-by-step explanation:
Let's call A the event that the sandwich was made with raspberry Jelly and B the event that the sandwich was made with creamy peanut butter.
So, the probability P(A∪B) that a randomly chosen sandwich was made with raspberry jelly or creamy peanut butter is calculated as:
P(A∪B) = P(A) + P(B) - P(A∩B)
Where P(A) is the probability that a sandwich was made with raspberry jelly, P(B) is the probability that it was made with creamy peanut butter and P(A∩B) is the probability that it was made with raspberry jelly and creamy peanut butter.
So, replacing P(A) by 0.84, P(B) by 0.27 and P(A∩B) by 0.19, we get that P(A∪B) is equal to:
P(A∪B) = 0.84 + 0.27 - 0.19
P(A∪B) = 0.92
The probability that a randomly chosen sandwich was made with raspberry jelly or creamy peanut butter is 0.92, or 92%, computed using the formula for the probability of A or B happening in probability theory.
Explanation:
In probability, when we want to find the probability of event A or event B happening, we use the formula P(A U B) = P(A) + P(B) - P(A ∩ B). Here, event A is the event that a sandwich was made with raspberry jelly, and event B is the event that it was made with creamy peanut butter. Given P(A) = 0.84, P(B) = 0.27, and P(A ∩ B) = 0.19, we can substitute these values into the formula.
So, P(A U B) = P(A) + P(B) - P(A ∩ B) = 0.84 + 0.27 - 0.19 = 0.92.
This means that the probability that a randomly chosen sandwich was made with raspberry jelly or creamy peanut butter is 0.92, or 92%.

A cooking magazine shows a photo of a main dish on the front cover of 5 out of the 12 issues it publishes each year,how many times will it be on front cover for 5 years
Answer:
The correct answer is 25.
Step-by-step explanation:
A cooking magazine shows a photo of a main dish on the front cover of 5 out of the 12 issues it publishes each year.
Number of publications by the magazine every year = 12.
Number of publications in 5 years = 12 × 5 = 60.
Out of these 12 magazines in a year, the photo of a main dish is on 5 magazines.
Therefore in 60 magazines, the photo of a main dish would be 5 × 5 = 25 magazines.
Thus in five years there would be 25 publications in which the front page will have a poster of a main dish.
Based on the number of times the photo appears per year, in 5 years it will appear 25 times.
Every year, the photo in question appears 5 out of 12 times.
If there were 5 years therefore, it would appear:
= Number of times per year x Number of years
= 5 x 5
= 25 times
In conclusion, the photo of a main dish will appear 25 times in 5 years.

At the 2010 Winter Olympics in Vancouver, the top 8 countries got a total of 60 gold medals. Of the 60, Russia got 3 gold medals. Write and solve an equation to find what percent of the total gold medals, for the top countries, Russia got.
Russia obtained [tex]\( 5\% \)[/tex]of the total gold medals for the top 8 countries.
Let's denote the total number of gold medals obtained by Russia as [tex]\( x \)[/tex]. Since we know Russia got 3 gold medals, we have [tex]\( x = 3 \)[/tex].
Now, let's denote the total number of gold medals obtained by the top 8 countries (including Russia) as T. We're told that the total number of gold medals obtained by all top 8 countries combined is 60. Since Russia got 3 gold medals, the gold medals obtained by the other top 7 countries is [tex]\( T - 3 \)[/tex].
So, the percentage of gold medals obtained by Russia can be calculated as:
Percentage of gold medals obtained by Russia = [tex]\frac{\text{Number of gold medals obtained by Russia}}{\text{Total number of gold medals obtained by the top 8 countries}} \times 100\%\][/tex]
Substituting the known values:
[tex]\[\text{Percentage of gold medals obtained by Russia} = \frac{3}{T} \times 100\%\][/tex]
We know that the total number of gold medals obtained by the top 8 countries is 60, so [tex]\( T = 60 \).[/tex] Substituting this into the equation:
[tex]\[\text{Percentage of gold medals obtained by Russia} = \frac{3}{60} \times 100\%\][/tex]
Solving this equation:
[tex]\[\text{Percentage of gold medals obtained by Russia} = \frac{1}{20} \times 100\% = 5\%\][/tex]
So, Russia obtained [tex]\( 5\% \)[/tex]of the total gold medals for the top 8 countries.

3n^2−2n−8 Factoring trinomials II
Answer:
(3n + 4) (n-2)
Step-by-step explanation:
Are you asking to factor this 3n^2 - 2n -8 ?
If so the best way to do this problem is with the X method.
top: 3*(-8)
left: factor of 3*-8 right: factor of 3*-8
bottom: -2
try the factors 4 and -6 because 4*-6 = 3 *-8 = -24
Because notice that 4 + -6 = -2
so:
3n^2 -2n - 8 can be rewritten as 3n^2 -6n + 4n - 8
We should first use Distributive property to factor: 3n^2 -6n + 4n - 8
3n^2 -6n + 4n - 8 = 3n (n - 2) + 4(n - 2)
Now we factor by grouping here : (3n + 4) (n-2)
I factored out the group (n-2)
Therefore: (3n + 4) (n-2) = 3n^2 -2n - 8
