Answer:
he needs 20.25 bags of sand and it would cost her 80.79
Step-by-step explanation:
150cm*90cm*15cm=202,500cm^3 this is how much sand she needs to fill it
202,500cm^3/10,000cm^3=20.25 this is how many bags he needs
3.99*20.25=80.79 this is how much it'll cost him for all 20.25 bags

in a given classroom the number of girls is 10 greater than number of boys if the ratio of the number of girls to the number of boys is 7:5 then find a) the number of girls b) the number of boys c) the total number of students
Answers
Answer:
a) 35, b) 25, c) 60
Step-by-step explanation:
The number of girls is 10 more than the number of boys, so it's a good thing to choose a variable to represent the number of boys.
Number of boys: b
Number of girls: b + 10
Ratio of girls:boys is 7:5, so
\(\frac{b+10}{b}=\frac{7}{5}\)
"Cross multiply" to get
\(7b=5(b+10)\\7b=5b+50\\2b=50\\b=25\)
There are 25 boys. There are 10 more girls, so the number of girls is 35, and the total number of students is 60.

In 15 words or fewer, will dividing the two polynomials in the table produce another polynomial? Why or why not?
Answers
Dividing two polynomials may produce another polynomial only when the divisor has a lower degree than the dividend. Otherwise, it will generally result in a rational function.
No, dividing two polynomials may not result in another polynomial. It can produce a rational function.
A polynomial is an algebraic expression consisting of terms with non-negative integer exponents. When two polynomials are divided, the result is not always a polynomial.
If the degree of the polynomial being divided (dividend) is higher than the degree of the polynomial dividing (divisor), then the result can be a polynomial with a lower degree. However, if the degree of the divisor is equal to or greater than the degree of the dividend, the result will generally be a rational function, which is a ratio of two polynomials.
A rational function has the form P(x)/Q(x), where P(x) and Q(x) are polynomials and Q(x) is not equal to zero. The division can introduce terms with negative or fractional exponents, making the result a rational function rather than a polynomial.

solve the following systems of linear equations by elimination y = 8 2x - 3y = -8
Answers
Answer:
x = 8
y = 8
Step-by-step explanation:
y = 8
2x - 3y = -8
We substitute 8 in for y and solve for x
2x - 3(8) = -8
2x - 24 = -8
2x = 16
x = 8
Let's Check the answer.
2(8) - 3(8) = -8
16 - 24 = -8
-8 = -8
So, x = 8 and y = 8 is the correct answer.
Answer:
x = 8 and y = 8.
Step-by-step explanation:
To solve the system of linear equations using the elimination method, we'll eliminate the variable "y" by substituting the given value of y into the second equation. Let's start:
Given equations:
y = 8
2x - 3y = -8
Substitute y = 8 into equation 2:
2x - 3(8) = -8
2x - 24 = -8
Next, we'll solve this equation for x:
2x - 24 = -8
2x = -8 + 24
2x = 16
x = 16/2
x = 8
Now that we have the value of x, we can substitute it back into equation 1 to find the value of y:
y = 8
So, y = 8
Therefore, the solution to the given system of equations is x = 8 and y = 8.

Use the given information to find the unknown value. Y varies inversely with the cube of x. When x=5, then y=1. Find y when x=1
Answers
Answer:
125
Step-by-step explanation:
y = 1k/x^3 I am trying to find the constant k. I will use the information that I have been given to find k
1 = k/5^3
1 = k/125 Multiply both sides by 125
125 = k
Now, we will find y when x = 1
y = 125/1^3
y = 125
The value of y is 125 when x is 1.
Write the function y as a function of x, i.e., y = f(x), and then solve for x as a function of y, to determine the inverse of a function.
y = 1k/x^3 I am trying to find the constant k. I will use the information that I have been given to find k

Answers
Answer:
0.14
Step-by-step explanation:
If winning holds a probability of 0.5 and a draw holds a probability of 0.3, then that means that losing has a probability of 0.2 (1 - 0.5 - 0.7 = 0.2). Therefore, to find the probability of Vishi losing exactly one of the two games we need to multiply the probability of him losing one game by the probability of him winning or tying the second game like so...
0.2 * (0.5 + 0.3) = x
0.2 * 0.7 = x
0.14 = x
Finally, we can see that the probability of Vishi losing exactly one of the two games is 0.14

if s represents a statement, then "not s" is called the negation of s. true or false?
Answers
The negation of a statement s is called "not s." Hence, the statement "not s" is the negation of s.
What is the term used to describe the opposite of a statement s?The statement "not s" is called the negation of s, and it represents the opposite meaning of the original statement s. If s is true, then "not s" is false, and if s is false, then "not s" is true.
The negation of a statement is an important concept in logic, and it is used to prove or disprove the original statement by contradiction. By assuming the negation of the statement, we can try to show that it leads to a contradiction or an absurdity, which would imply that the original statement must be true.
In mathematics and other fields, the ability to negate a statement is a crucial tool for constructing proofs and solving problems.
The use of negation allows us to reason about the relationships between different statements and to establish the validity of arguments and claims.

1. A rabbit can hop 6 feet in 2 seconds and 12 feet in 4 seconds. If the number of feet varies directly with the time the rabbit spends hopping, at what speed is the rabbit hopping?
Answers
Answer: The rabbit is hopping at 3 feet/ sec in speed
Step-by-step explanation:
Step 1
Let the The number of feet of the rabbit be expressed as N
AND time rabbit spends hopping can be expressed as t
From the question, The number of feet varies directly with the time rabbit spends hopping can be expressed as
N α t
Let us introduce a constant of proportionality ,S which represents speed in this case, we now have that
N = St
STEP 2 -- SOLVING
If the rabbit hop 6 feet in 2 seconds, Then speed =
N = St
6= S X2
S = 6/ 2
S = 3
also
If the rabbit hop 12 feet in 4 seconds, Then speed =
N = St
12= S X 4
S = 12/ 4
S = 3
Also recall
that Speed = Distance / time
Pluging the values in the first case,
speed = 6 feet/ 2 secconds = 3 feet/ seconds
in the second case
Speed= 12 feet/ 4 second s= 3 feet/ secs.

The sum of the interior angles of a polygon with n sides is given by:
Sum = (n - 2) * 180
We are given that the sum of the interior angles is 1800 degrees. Setting these two expressions equal to each other, we get:
(n - 2) * 180 = 1800
Dividing both sides by 180, we get:
n - 2 = 10
Adding 2 to both sides, we get:
n = 12
Therefore, the polygon has 12 sides.

The number of bicycles they need to sell to make equal money is 5. The amount they would make is $500.
What is fixed and variable cost?In contrast to variable costs, which change depending on the volume of production or sales, fixed costs are expenses that remain constant. Rent, insurance, and salary are examples of fixed costs that are constant regardless of the volume of output or sales. Materials, labour, and shipping expenses are examples of variable costs that change according to the volume of output or sales.
Let us suppose the number of bicycle sold = x.
Then the equation for Jimmy is:
$250 + 50x
The equation for Tom is:
$400 + 20x
To make the same amount we equate the two equations as follows:
250 + 50x = 400 + 20x
30x = 150
x = 5
Substituting the value of x in equation 1 we have:
J = 250 + 50(5)
J = 250 + 250
J = 500
Hence, the number of bicycles they need to sell to make equal money is 5. The amount they would make is $500.
