The probability that he first selects a blue marble and then selects a red marble is 4/15.
What is Probability?It is a branch of mathematics that deals with the occurrence of a random event.
Given,
The number of red marbles in bag=4
The number of blue marbles in bag=6
The total number of marbles in bag are 4+6=10
The probability of selecting a blue ball is 6/10
The probability of selecting a red ball without replacement is 4/9
So the probability that he first selects a blue marble and then selects a red marble
6/10×4/9
24/90
4/15
Hence the probability that he first selects a blue marble and then selects a red marble is 4/15.

8x-2y=12 solve for y and slope
The required solution is y = 4x - 6 and slope is 4.
What is the equation of line?The general equation of straight line is
y = mx + c
where, m is the slope
and c is the intercept where the line cuts the y-axis.
Now the given equation is,
8x - 2y = 12
Dividing whole equation by 2 we get
4x - y = 6
Substacting 4x to the both side,
4x - y -4x = 6 -4x
Solving,
- y = 6 -4x
Multiplying whole equation by -1 we get,
y = 4x - 6
Comparing the above equation with the general equation of line
y = mx + c
Hence we get,
m= 4 which the slope,
and c = -6
Hence,the required solution is y = 4x - 6 and slope is 4.

To find how many kilograms of dissolved salt are in the Pacific Ocean, multiply the amount of salt per liter by the total volume of water, giving a total of 2.31 x 10^19 kg.
The Pacific Ocean contains approximately 6.6 × 1020 liters of seawater, with an average of 3.5 x 10-2 kilograms of dissolved salt per liter.
To calculate the total amount of salt in the Pacific Ocean, you multiply the amount of salt per liter by the total volume of water.
So, the total amount of salt in the Pacific Ocean is 2.31 x 1019 kg.
what number is 5% of 60?
Answer: 3
Step-by-step explanation: To find 5% of 60, first rewrite 5% as a decimal by moving the decimal point two places to the left to get .05.
Next the word "of" tells us we need to multiply so we multiply .05 by 60.
(.05) (60) = 3.00
Therefore, 5% of 60 is 3.

Two less than the product of a number and -5 is -42
The value of that number such that two less than the product of a number and -5 is -42 will be 8.
What is multiplication?Multiplication is the general procedure in mathematics in which we multiply two or more numbers to each other to find a new multiplied number.
If and only if the number being multiplied is more than one, multiplication produces a resultant number that is significantly larger than the original number.
Let's say that number is x
Given condition
Product of x and -5 = -5x
Two is less than = -5x -2
Equal to -42
So,
-5x - 2 = - 42
x = 8
Hence the correct answer is 8.

what is the definition of perfect cube and can you give an example
Final answer:
A perfect cube is a number that results from an integer being multiplied by itself two additional times. The number 27 is an example of a perfect cube, which is the result of 3 × 3 × 3. While the concept of a cube is also significant in chemistry, the mathematical perfect cube is different from geometric or chemical descriptions of cubes.
Explanation:
A perfect cube is a number that can be expressed as the product of an integer multiplied by itself three times. It is the cube of an integer. For instance, when you multiply 3 × 3 × 3, you get 27, which is a perfect cube because it is the result of an integer (3) multiplied by itself two more times.
The number 27 is an example of a perfect cube in mathematics.A Rubik's cube, such as the one described with a volume of 185.2 cm³, is a real-world example of a cubic shape, although not related to the mathematical concept of a perfect cube.The properties of geometric shapes, like a cube, are significant in various fields, including chemistry, where the concepts of face-centered cubic unit cell become important in studying crystal structures.

What is the value of g? 25(g−7)=3 Enter your answer in the box
Answer: The value of g is 7.12.
Explanation:
The given equation is,
[tex]25(g-7)=3[/tex]
Use distributive property to solve the equation.
[tex]25g-175=3[/tex]
Using addition property of equality add 175 both sides.
[tex]25g-175+175=3+175[/tex]
[tex]25g=178[/tex]
Using division property of equality, divide both sides by 25.
[tex]\frac{25g}{25} =\frac{178}{25}[/tex]
[tex]g=\frac{178}{25}[/tex]
[tex]g=7.12[/tex]
Therefore the value of g is 7.12.
To check the answer put the value of g in given equation.
[tex]25(7.12-7)=3[/tex]
[tex]25(0.12)=3[/tex]
[tex]3=3[/tex]
LHS is equal to RHS, therefore the value g=7.12 is correct.

Atticus wants to buy of a square yard of wrapping paper. The paper costs $2.40 per square yard. How much will Atticus spend on the wrapping paper?
a.$1.60
b.$4.80
c. $7.20
d. $9.20
Final answer:
Atticus will spend $1.80 on the wrapping paper when purchasing ¾ of a square yard at a cost of $2.40 per square yard, multiplying 0.75 by 2.40. However, this is not an option provided, indicating a possible typo. The closest choice to the correct answer given the options would be $1.60. (Option a)
Explanation:
The question asks how much Atticus will spend if he wants to buy ¾ of a square yard of wrapping paper, and the cost of one square yard of wrapping paper is $2.40. To find the cost of ¾ of a yard, we multiply ¾ by the cost per square yard. Here is the calculation:
Cost of ¾ yard = ¾ * $2.40
First, we convert ¾ into a decimal to make multiplication easier:
¾ = 0.75
Now, multiply:
0.75 * $2.40 = $1.80
Therefore, Atticus will spend $1.80 on the wrapping paper. However, this amount is not listed in the answer choices provided. If this is simply an error in the choices given, Atticus would spend $1.80, but based on the options presented, the closest correct choice would be (a) $1.60, suggesting there may be a typo in the question.
