A class is presented with the following problem.
In a bag of marbles, the ratio of white marbles to red marbles is 2:3 and the ratio of red to black marbles is 6:11. What is the ratio of white to black marbles?
Connor, who likes using fractions, writes 2/3 *6/11 = 4/11 announces, without explanation, that the ratio of white to black marbles is 4:11. Explain why he is right. (Hint: taking the number of black marbles to be the whole unit, what fraction are red, and then what fraction are white?)
Answer:
Therefore, Connor is correct in his explanation that the ratio of white to black marbles is 4:11.
Step-by-step explanation:
Connor is correct in his reasoning. Let's break down the problem step by step to understand why.
Given:
Ratio of white marbles to red marbles = 2:3
Ratio of red marbles to black marbles = 6:11
To find the ratio of white to black marbles, we can follow these steps:
Step 1: Consider the black marbles as the whole unit.
Let's assume there are 11 black marbles (since the ratio of red to black marbles is 6:11).
Step 2: Determine the number of red marbles.
Since the ratio of red marbles to black marbles is 6:11, out of the assumed 11 black marbles, there are (6/11) * 11 = 6 red marbles.
Step 3: Determine the number of white marbles.
Using the ratio of white marbles to red marbles (2:3), we can find the number of white marbles. Since the ratio is 2:3, the number of white marbles would be (2/3) * 6 = 4.
Step 4: Find the ratio of white to black marbles.
Now that we have determined there are 4 white marbles and 11 black marbles, the ratio of white to black marbles is indeed 4:11.
Two lines AB and CD intersect each other at O.If angle AOD = 120 deg . BOC=3y. < BOD = 2x then find (x + y)
The value of x + y = 70 when 2 lines AB and CD intersect each other at O. If angle ∠AOD = 120 degree, ∠BOC=3y and ∠BOD = 2x.
Given that,
AB and CD 2 lines intersect each other at O. If angle ∠AOD = 120 degree, ∠BOC=3y and ∠BOD = 2x.
We have to determine the value of (x + y).
We know that,
In the picture we can see the two lines AB and CD intersect each other at O.
So,
From line AB a straight line has 180°.
Then ∠AOD + ∠DOB = 180°
120° + 2x = 180°
2x = 180° - 120°
2x = 60
x = [tex]\frac{60}{2}[/tex]
x = 30°
Then ∠DOB = 2x = 2(30) = 60°
And by vertically opposite angles ∠AOD = ∠COB
120° = 3y
3y = 120°
y = [tex]\frac{120}{3}[/tex]
y = 40°
Then ∠COB = 120°
So,
Now, x + y = 30 + 40 = 70
Therefore, The value of x + y = 70

Bob the builder is making 480kg of a concrete mix. Concrete is made by mixing cement , said and gravel in ratio 1:3:4.
How much sand does he need?
Answer:
x = the number of kg of cement
3x = number of kg of sand
4x = number of kg of gravel
x + 3x + 4x = 480
8x = 480, so x = 60
60 kg of cement
3(60) = 180 kg of sand
4(60) = 240 kg of gravel
Bob will need 180 kg of sand.
Y-3=2(x-6) what point does this line pass through? What is the slope of this line ? Rewrite the equation in slope intercept form
Answer:
This line passes through (0, -9)
Slope = 2
y = 2x-9
Step-by-step explanation:
Slope intercept form is : y=mx+b (m = slope, b= y-intercept)
First, let's distribute the 2 to the (x-6).
y-3 = 2x-12
Second, set it into slope intercept form (y = mx+b) by adding 3 to both sides.
y = 2x-9
This will be the equation in slope intercept form.
After looking at the the slope intercept form, we know that m = the slope. So the since the 2 is in the place of m when in slope intercept form, m=2. this would mean that the slope = 2.
Y-intercept is the point when the line touches the y-axis. To find the y-intercept, x would have to equal 0. This would mean that the point would have to be (0, y). After looking at the slope intercept form, and comparing it with our equation in slope intercept form, we know that -9 is in the place of b. This would mean that b = -9. This would also mean that the y-intercept is equal to -9. Therefore, the point would be (0, -9).

We are 95% confident that the true mean incubation period of the SARS virus lies between 2.79 and 9.01 days.
This means that if we were to sample many times from the same population, 95% of the intervals we construct would contain the true mean value.
Hence, Using a t-distribution with 86 degrees of freedom (n-1), and a 95% confidence level (α=0.05), the critical value for the two-tailed test is 1.992.
The standard error can be calculated as:
SE = SD / √n = 15.6 / √100 ≈ 1.56
The margin of error (ME) can be calculated as:
ME = t x SE = 1.992 x 1.56 ≈ 3.11
The 95% confidence interval (CI) is then:
CI = mean ± ME = 5.9 ± 3.11 = (2.79, 9.01)
Therefore, we are 95% confident that the true mean incubation period of the SARS virus lies between 2.79 and 9.01 days.

name the leading coefficient and degree of the polynomial 12+5x^y+4x
Answer:
The leading coefficient is 5, the degree is y+1
Step-by-step explanation:
The polynomial 12+5x^y+4x has two terms, 12 and 5x^y+4x. The leading coefficient of the polynomial is 5, which is the coefficient of the term with the highest degree. The degree of the polynomial is y+1, which is the highest power of x in any term of the polynomial after like terms have been combined. The degree is determined by adding the exponents of the variables in the term with the highest degree, which is 5x^y in this case. The exponent of x is 1 and the exponent of y is y, so the degree is y+1. Therefore, the leading coefficient is 5 and the degree is y+1.

A. about 6.25 hours
B. about 385.00 hours
C. about 5.92 hours
D. about 3.21 hours
Option C. It t will take approximately 5.923 hours to drive the same distance at 65 miles per hour.
How to solve for the time takent = k / r
where k is the constant of variation.
First, we need to find the constant of variation, k, using the given information:
t = 7 hours when r = 55 mph
7 = k / 55
To find k, multiply both sides by 55:
k = 7 * 55 = 385
Now that we have the constant of variation, we can find the time it will take to drive the same distance at 65 mph:
t = k / r
t = 385 / 65
t ≈ 5.923 hours
So, it will take approximately 5.923 hours to drive the same distance at 65 miles per hour.

Determine the number of real solutions:
1. y=-3x^2+x+12
Answer:
2
Step-by-step explanation:
To determine the number of real solutions of the quadratic equation `y = -3x^2 + x + 12`, we can use the discriminant formula `b^2 - 4ac`.
First, we identify the values of a, b, and c:
a = -3
b = 1
c = 12
Next, we substitute these values into the discriminant formula:
b^2 - 4ac = (1)^2 - 4(-3)(12) = 145
Since the discriminant is positive (and not equal to zero), the quadratic equation has two distinct real roots. Therefore, the number of real solutions is 2.
how do you solve 3/(n-1) = 2n/(n+4)
Step-by-step explanation:
To solve the equation 3/(n-1) = 2n/(n+4), follow these steps:
Step 1: Cross-multiply to eliminate the fractions.
3 * (n + 4) = 2n * (n - 1)
Step 2: Distribute the terms on both sides.
3n + 12 = 2n^2 - 2n
Step 3: Move all terms to one side and set the equation to zero.
2n^2 - 5n - 12 = 0
Step 4: Factor the quadratic equation, if possible. In this case, we can factor by finding two numbers that multiply to -24 and add to -5.
(2n + 3)(n - 4) = 0
Step 5: Use the zero-product property, which states that if the product of two factors is zero, then at least one of the factors must be zero.
2n + 3 = 0 or n - 4 = 0
Step 6: Solve for 'n' in each equation.
2n + 3 = 0 => n = -3/2
n - 4 = 0 => n = 4
So, there are two possible solutions for 'n': -3/2 and 4.
Answer: n= 4 , (-3/2)
Step-by-step explanation:
Your goal is to isolate n by getting it by itself
Multiply both sides by (n-1) to get 3 = ((2n)(n-1))/(n+4)
Use distributive property on the 2n * (n-1) to get 3 = (2n^2 - 2n)/(n+4)
Multiply both sides by (n+4) to get 3n + 12 = 2n^2 - 2n
Subtract 12 and 3n from both sides to get 2n^2 - 5n -12 = 0
Solve the quadratic using any method you like
Factoring would give you (n - 4)(2n + 3) = 0
So n= 4 and -3/2
