A bag contains 8 blue marbles 5 red marbles and 2 orange marbles , Carolina picks a marble from the bag at random and returns it to the bag and makes a second random selection . What is the probability that two blue marbles were selected
Answers
Initial number of blue marbles: 8
First pick:
p(blue marble) = 8/15
Since the marble from the first pick is returned to the bag, the bag still contains 8 blue marbles and a total of 15 marbles.
Second pick:
p(blue marble) = 8/15
Overall:
p(blue marble followed by blue marble) =
= p(blue marble) * p(blue marble)
= 8/15 * 8/15
= 64/225
The center of a circle is at (-5, 7) and its radius is 6 units. Which of the following is the equation for this circle?
A) (x - 5)2 + (y + 7)2 = 36
B) (x + 5)2 + (y - 7)2 = 36
C) (x - 5)2 + (y + 7)2 = 12
D) (x + 5)2 + (y - 7)2 = 12
Answers
Answer:
Option B, (x + 5)² + (y - 7)² = 36
Explanation:
The equation for a circle is (x - h)² + (y - k)² = r² where r represents the radius of the circle and the center is ordered pair (h, k).
We can then plug the given information into the formula and simplify where possible.
Center at (-5, 7), radius = 6:
[x - (-5)]² + (y - 7)² = (6)²
(x + 5) + (y - 7)² = 36, which matches option B.
The length of a rectangle is 5 cm longer than its width. find the width given that the area is 36cm
Answers
Let the width of the rectangle be represented by X.
Now we can conclude we can express the length by X + 5.
The area of a rectangle can be found using the formula:
A = W × L = width × length.
Filling in the formula gives us the following:
[tex]x(x + 5) = [/tex]
Work out the parenthesis (for instance using rainbow technique).
[tex] {x}^{2} + 5x[/tex]
Now, when we've found our expression that represents the area, we can set up and solve an equation.
[tex] {x}^{2} + 5x = 36[/tex]
Subtract 36.
[tex] {x}^{2} + 5x - 36 = 0[/tex]
Factorise
[tex](x + 9)(x - 4) = 0[/tex]
Rule AB = 0, gives A = 0 or B = 0
[tex]x + 9 = 0 \\ x = - 9 \\ or \\ x - 4 = 0 \\ x = 4[/tex]
Since length can't be negative, the width of the rectangle, which was represented by x, is 4.
The answer is 4 cm.

x = (- (- 2) +/- root ((- 2) ^ 2 - 4 * 4 * (- 5))) / (2 * 4)
x = (2 +/- root (4 + 80)) / (8)
x = (2 +/- root (84)) / (8)
x = (2 +/- root (4 * 21)) / (8)
x = (2 +/- 2raiz (21)) / (8)
x = (1 +/- root (21)) / (4)

the weight of an object on mars varies directly as the weight of the object on earth a 90 pound object on earth weighs 34 pounds on mars.if an object weighs 135 pounds on earth how much does it weigh on mars
Answers
We have been given that the weight of an object on the mars varies directly as the weight of the object on earth.
Let y be weight of an object on Mars and x be weight of an object on Earth.
[tex]\\ y=kx[/tex]
We have been given that the weight of an object on Mars is 34 pounds and weight of the same object on Earth is 90 pounds.
Putting the given values in equation we get
[tex]\\ 34=k(90)\\ \\ k=\frac{34}{90}=\frac{17}{45}[/tex]
Therefore, our equation now becomes
[tex]\\ y= \frac{17}{45}x[/tex]
Now we have been given that the weight of an object on Earth is 135 pounds and we have to find the weight of the same object on Mars,
We have been given that [tex]\\ x=135[/tex]
Putting the given values in our equation we get
[tex]\\ y= \frac{17}{45}(135)=\frac{17\cdot 135}{45}=17\cdot 3 = 51[/tex]
Therefore weight of the object on Mars will be 51 pounds.

The height of a triangular road sign is 1 inch shorter than twice its base. if the area of the sign is 60 in.2, which equation could be used to find the base (b) of the sign?
Answers
The equation that can be used to find the base of the triangular road sign is 60 = (b * (2b - 1)) / 2.
Explanation:Let's assume that the base of the triangular road sign is represented by b. According to the problem, the height of the sign is 1 inch shorter than twice its base, which can be written as:
height = 2b - 1
The area of a triangle can be calculated using the formula Area = (base * height) / 2. Substituting the given values into the formula, we get:
60 = (b * (2b - 1)) / 2
This equation can be used to find the base, b, of the sign.

what is the largest possible product of two odd integers whose sum is 42?
Answers
You can tell this because the largest area of any rectangle is when it is a square. Even sides will always produce the greatest area. Thus, 21 and 21 would be the best numbers to use.
The largest possible product of two odd integers whose sum is 42 is 437, obtained from multiplying 19 by 23.
The question asks for the largest possible product of two odd integers whose sum is 42. To find this, we should split 42 into two odd numbers that are as close to each other as possible because the product of two numbers that are close together will be higher than the product of a pair that has a larger difference.
If we divide 42 by 2, we get 21, which is not an even integer, so we need to adjust the numbers by 1. So the two odd numbers closest to each half of 42 are 21 and 21. However, we can't have them both be the same number since we're looking for two integers, so we adjust one up and one down by 1, resulting in 20 and 22. To ensure both numbers are odd, we will subtract 1 from the first number and add 1 to the second number, giving us 19 and 23 as the two odd integers that sum to 42.
The product of 19 and 23 is 19 × 23 = 437, which is the largest possible product for two odd integers that add up to 42.
