Select all of the rational numbers. (there can be more than one)
3^-1
square root of 12
square root of 9
-0.25
pi
0.6 (the six has a line over it)
Answer:
3^-1, square root of 9, -0.25, and 0.6
Step-by-step explanation:
Rational numbers are numbers that you can turn into fractions.
3^-1 = 0.3333333333... which is also known as 1/3
square root of 9 = 3, which can be written as 3/1
-0.25 can be written as -1/4
0.66666666... = 2/3
The numbers 3⁻¹ , sqrt(9), -0.25 and 0.6 are the rational numbers.
What is Number system?A number system is defined as a system of writing to express numbers.
The rational numbers are those that can be expressed as a ratio of two integers.
3⁻¹ = 1/3, which is a rational number.
sqrt(12) = sqrt(4 x 3) = 2sqrt(3), which is irrational.
sqrt(9) = 3, which is a rational number.
-0.25 = -1/4, which is a rational number.
pi is irrational.
0.6 = 3/5, which is a rational number.
Hence, 3⁻¹ , sqrt(9), -0.25 and 0.6 are the rational numbers.

You are selling tickets for a high school basketball game. Student tickets cost $3 and general admission tickets cost $5. You sell 350 tickets and collect $1450. How many of each type of ticket did you sell?
Answer:
5 stars? Answer down below
Step-by-step explanation:
a+b=350 => a=350 - b
3a + 5b = 1450
3(350-b)+b=1450
1050-3b+5b=1450
2b=400
b=200
a=150
There are 200 student ticket and 150 general admission ticket sold.
What is selling price?The selling price is used to sell the item at a certain cost and can be calculated using the selling price formula. The amount that the buyer pays to buy the product is called the selling price.
Here,
We sold some number, x, of $5 tickets and some number, y, of $3 tickets. If we sold 350 tickets total then x + y = 350. If we made $1450 total on ticket sales, then the sum of y tickets at $3 plus x tickets at $5 needs to equal $1450.
So,
$3y + $5x = $1450
and x + y = 350
Solve system of equations.
3(350-x) + 5x = 1450
1050 -3x + 5x = 1450
2x = 400
x=200
y + 200 = 350
y=150
Thus, there are 200 student ticket and 150 general admission ticket sold.

(04.05)Marcus spent 10 hours doing his homework last week. This week he spent 11 hours doing homework. He says that he spent 110% more time doing homework this week. Is he correct? Show your work to justify your decision.
Answer:
No
Step-by-step explanation:
No he is not correct because,
11 - 10 = 1
So he spent 1 more hour this week. So.....
1/10 x 100 = 10% more which is not 110%.

The vertex of the parabola described by the equation 3y=2x^2-16x+18 is (m,n). What is m+n?
Answer:
the aswer is 32
Step-by-step explanation:
The vertex of the parabola described by the equation 3y=2x^2-16x+18 is (m,n). the sum of m + n is 178/27.
To find the vertex of the parabola described by the equation 3y = 2x^2 - 16x + 18, we first need to put the equation in the standard form of a parabola, which is y = a(x - h)^2 + k, where (h, k) represents the vertex.
Let's begin by dividing the entire equation by 3 to simplify it:
y = (2/3)x^2 - (16/3)x + 6
Now, we need to complete the square to rewrite the equation in the form y = a(x - h)^2 + k:
y = (2/3)(x^2 - (8/3)x) + 6
Next, we need to find the value that completes the square for the expression inside the parentheses. To do that, we take half of the coefficient of x and square it:
(8/3) / 2 = 4/3
(4/3)^2 = 16/9
Now, we add and subtract 16/9 inside the parentheses:
y = (2/3)(x^2 - (8/3)x + 16/9 - 16/9) + 6
Now, we group the first three terms and factor the perfect square trinomial:
y = (2/3)((x - 4/3)^2 - 16/9) + 6
Next, distribute the (2/3):
y = (2/3)(x - 4/3)^2 - (2/3)(16/9) + 6
Now, simplify:
y = (2/3)(x - 4/3)^2 - (32/27) + 6
Finally, bring everything together:
y = (2/3)(x - 4/3)^2 + (142/27)
Now we can see that the vertex of the parabola is at the point (h, k) = (4/3, 142/27).
To find m + n, we simply add the x-coordinate (h) and the y-coordinate (k):
m + n = 4/3 + 142/27
To add these fractions, we need to find a common denominator, which is 27. Convert 4/3 to have a denominator of 27:
4/3 = (4/3) * (9/9) = 36/27
Now we can add the fractions:
m + n = 36/27 + 142/27
m + n = (36 + 142)/27
m + n = 178/27

The length of the Titanic was 882 feet. Porter's history class is building a model of the Titanic. The model is 1/100 of the actual length of the ship. How long is the model?
Answer:
8.82 feet
Step-by-step explanation:
Explanation:
Let's set up the ratio. We know that the actual length of the ship was 882 feet and we want to know how long the model will be. We also have a ratio of 1 model length to every 100 actual length. So we can write this as:
Model length
Ship length
=
1 Model length
100 actual length
And we can drop in some numbers (I'll also put in the variable
x
to represent the length of the ship model):
x

=

100
Let's cross multiply to solve for x:
