Find a completely simplified expression for the perimeter (2 ⋅ length + 2 ⋅width) of the blue rectangle:
Answers
Answer: 18x-12
Step-by-step explanation:
2(6x+2+3x-8)
2(9x-6)
18x-12
The perimeter of the shown rectangle is given by the equation:
P = 2*(6x + 2)*(3x - 8)
How to get the perimeter?For a rectangle of length L and width W, the perimeter is:
P = 2*(L + W).
Here we have:
L = 6x + 2
W = 3x - 8
Replacing that in our equation, we get:
P = 2*(6x + 2)*(3x - 8)
So the perimeter is given by the above quadratic equation.

Brainlist for positive attitude and correct answer :D
Answers
Answer: The correct answer is:
Probability of rolling a number less than 3: 2/6 or 1/3
Step-by-step explanation:
Explanation: Out of the six possible outcomes (numbers 1, 2, 3, 4, 5, 6), there are two outcomes that meet the condition of rolling a number less than 3, which are 1 and 2. Therefore, the probability of rolling a number less than 3 is 2 out of 6, which simplifies to 1/3.
Probability of not rolling a number less than 3: 4/6 or 2/3.
Explanation: To find the probability of not rolling a number less than 3, we consider the outcomes that are not favorable (i.e., rolling a 3, 4, 5, or 6). There are four such outcomes, so the probability of not rolling a number less than 3 is 4 out of 6, which simplifies to 2/3. :D

Yolanda's Coffee Shop makes a blend that is a mixture of two types of coffee. Type A coffee costs Yolanda $5.20 per pound, and type B coffee costs $4.05 per
pound. This month, Yolanda made 130 pounds of the blend, for a total cost of $586.30. How many pounds of type B coffee did she use?
Answers
Answer:
78 pounds
Step-by-step explanation:
Let's say Yolanda makes a pounds of Type A coffee and b pounds of Type B coffee. Since the total number of pounds is 130, we can write the equation:
a + b = 130
We know the cost of Type A coffee is $5.20/lb and the cost of Type B coffee is $4.05/lb, so since the total cost is $586.30, we can write:
5.20a + 4.05b = 586.30
We can now solve the system of equations:
a + b = 130
5.20a + 4.05b = 586.30
Manipulate the first equation by subtracting b from both sides:
a + b = 130
a = 130 - b
Substitute 130 - b for a in the second equation:
5.20a + 4.05b = 586.30
5.20 * (130 - b) + 4.05b = 586.30
676 - 5.20b + 4.05b = 586.30
Move the terms with b to one side:
1.15b = 89.70
b = 78
Thus, Yolanda used 78 pounds of Type B coffee.

Answers
Answer:
18 : 3
Step-by-step explanation:
Basic proportionality question. All we need to here is to expression the given fractions ( \(11 \frac{2}{3}\), and \(1 \frac{17}{18}\) ) as a fraction itself, and hence expressing the ratio we need to get, in fraction form.
\(11 \frac{2}{3} / 1 \frac{17}{18}\\\\\) - So, we have expressed this in a fraction, which we want to reduce
\(= \frac{35}{3} / \frac{35}{18}\) - The fractions have been taken as improper fractions
\(\\\\= \frac{35}{3}( \frac{18}{35} )\\ \\\) - Now we took the inverse fraction, through multiplication
\(= 18 / 3\) - 35 and 35 cancel out, leaving us with the simplified fraction 18 / 3
_____
So now we have 18 / 3, the ratio in fraction form. The scale is thus 18 to 3, or in other words 18 : 3.

Answers
The perimeter of the floor in the scale is 46 inches
What is perimeter?A perimeter is a closed path that encompasses, surrounds, or outlines either a two dimensional shape or a one-dimensional length. The perimeter of a circle or an ellipse is called its circumference.
The length of the actual floor is 22 feet and the length in scale is 11 cm. This means the scale factor is 2 feet is 1 inches
Therefore the the width of the floor in scale = 24/2 = 12 feet
Perimeter = 2( l+w)
therefore the perimeter of the floor in the new scale = 2(11+12)
= 2× 23
= 46 inches
therefore the floor in the scale drawing is 46 inches

HELP NEEDED NOW Measure the difference between the lower quartile of Data Set A and the lower quartile of Data Set B. Round to the nearest tenth when performing all operations.
Answers
Answer:
29
Step-by-step explanation:
The formula for lower quartile(Q1) = 1/4(n + 1)th term
Where n = number of terms.
For Data set A = 73, 75, 79, 81, 84, 85, 86, 86, 89, 91, 94, 95
n = 12
Q1 = 1/4 (n + 1) th term
Q1 = 1/4(12 + 1) th term
Q1 = 1/4(13) th term
Q1 = 3.25th term
The 3.25th term is data set A is between the 3rd and 4th term
3rd term = 79
4th term = 81
3.25th term = 79 + 81/2
= 160/2
= 80
For Data set B = 47, 49 , 51, 51, 55, 56, 57, 58, 59, 59, 61, 62
n = 12
Q1 = 1/4 (n + 1) th term
Q1 = 1/4(12 + 1) th term
Q1 = 1/4(13) th term
Q1 = 3.25th term
The 3.25th term is data set A is between the 3rd and 4th term
3rd term = 51
4th term = 51
3.25th term = 51 + 51/2
= 102/2
= 51
The difference between the lower quartile of Data Set A and Data Set B =
80 - 51 = 29
