A pizza is cut into six unequal slices (each cut starts at the center). The largest slice measures 90 degrees
If Larry eats the slices in order from the largest to the smallest, then the number of degrees spanned by a slice decreases at a constant rate. (So the second slice is smaller than the first by a certain number of degrees, then the third slice is smaller than the second slice by that same number of degrees, and so on.)
What is the degree measure of the fifth slice Larry eats?
A 150-unit apartment complex is infested with rats. The apartment caretaker checked 9 units and found the following number of rats {2, 5, 3, 1, 0, 3, 7, 2, 2}. If the sample data is representative of the rat population, how many units in the entire apartment complex have 3 rats?
To estimate the number of units in the entire apartment complex that have 3 rats, we can use the proportion of units in the sample that have 3 rats and apply it to the total number of units in the complex.
Explanation:To determine how many units in the entire apartment complex have 3 rats, we can use the concept of sampling. Since the apartment caretaker checked 9 units and recorded the number of rats in each, we can calculate the proportion of units with 3 rats in these 9 units. We can then apply this proportion to the entire apartment complex to estimate the number of units with 3 rats.
Out of the 9 units checked, there were 3 units with 3 rats. So the proportion of units with 3 rats in the sample is 3/9 = 1/3.
To estimate the number of units with 3 rats in the entire apartment complex, we can multiply the proportion of units with 3 rats in the sample (1/3) by the total number of units in the complex: 1/3 * 150 = 50. So, approximately 50 units in the entire apartment complex have 3 rats.

What is the ratio of the circumferences for two circles with areas 6π m and 150π m?
The ratio of the circumferences equals the ratio of the radii.
so we need to find their radii
first circle's radius:
pir^2 = 6pi
r = √6
second circle's radius:
pir^2 = 150pi
r = √150
Their ratio is
√6 : √150 =
√6 : √6√25 =
√6 : 5√6 =
1 : 5
The ratio of the circumferences of two circles with areas of 6π m² and 150π m² is 5:1.
To find the ratio of the circumferences of two circles given their areas, we first recall the formula for the area of a circle, A = πr², where A is the area and r is the radius. Knowing the area, we can solve for the radius of each circle. The areas given are 6π m² and 150π m².
To find the radius for the first circle, we set up the equation:
6π = πr²
We solve for r, yielding:
r = √6.
Similarly, for the second circle:
150π = πr²
This gives us:
r = √150.
Next, we use the formula for the circumference C = 2πr. We calculate the circumferences of the circles using their respective radii:
First circle's circumference: C1 = 2π(√6)
Second circle's circumference: C2 = 2π(√150)
Finally, to find the ratio of the circumferences, we divide C2 by C1 and simplify:
Ratio = C2÷C1 = (2π(√150))÷(2π(√6)) = √(150÷6) = √25 = 5.
Therefore, the ratio of the circumferences of the two circles is 5:1.

Which is true? A 10.59 > 10.60 B 10.590 = 10.59 C 10.43 < 10.24 D 9.0005 = 9.0050
A) 10.59 > 10.60: True, because 10.59 is greater than 10.60.
B) 10.590 = 10.59: True, as they have the same value.
C) 10.43 < 10.24: False, as 10.43 is greater than 10.24.
D) 9.0005 = 9.0050: False, as they are not equal.
Use the concept of mathematical expression defined as:
Using operations like addition, subtraction, multiplication, and division, a mathematical expression is defined as a group of numerical variables and functions.
A) 10.59 > 10.60: This statement is true.
In decimal numbers, the higher the number, the greater its value.
Since 10.59 is greater than 10.60 (because 59 is greater than 60), this statement holds true.
B) 10.590 = 10.59: This statement is also true.
When two decimal numbers have the same digits after the decimal point, they are considered equal.
In this case, 10.590 and 10.59 have the same value.
C) 10.43 < 10.24: This statement is false.
Similar to the first option, the higher the number, the greater its value.
In this case, 10.43 is greater than 10.24,
So the statement is not true.
D) 9.0005 = 9.0050: This statement is also false.
Although the numbers are very close, they are not equal.
When comparing decimal numbers, each digit after the decimal point matters.
In this case, the numbers differ after the fourth decimal place, making them unequal.
Hence, the given expressions:
A) 10.59 > 10.60: True,
B) 10.590 = 10.59: True,
C) 10.43 < 10.24: False,
D) 9.0005 = 9.0050: False.

The cheerleading team lines up down the football field to rally the spectators. If there are 12 cheerleaders, which expression gives the number of ways can they line up down the field?
Final answer:
The number of ways 12 cheerleaders can line up is calculated using permutations, specifically 12!, which is the product of all positive integers from 1 to 12.
Explanation:
The number of ways the 12 cheerleaders can line up down the football field can be calculated using the concept of permutations. A permutation is an arrangement of all or part of a set of objects, with regard to the order of the arrangement. For 12 cheerleaders, each of whom is distinct, the number of different ways they can line up is the same as the number of permutations of 12 objects, which is given by the factorial of the number of objects.
The formula for permutations of n objects is n! (n factorial), where n represents the total number of objects. Therefore, for 12 cheerleaders, the expression for the number of ways they can line up is:
12!
This is calculated as 12 × 11 × 10 × 9 × ... × 3 × 2 × 1. The value of 12! (12 factorial) gives us the total number of possible arrangements for the 12 cheerleaders.

Step-by-step explanation:
Mitch completes the course and his boss promotes him. Mitch receives a 25% increase on his previous pay of $40 000 per year after tax.
However, Mitch took out a Study Assist loan from the government to pay his course fee. This means that 4% of his new after-tax salary goes towards repaying the loan.
How much extra pay does Mitch actually end up with for the year?
Mitch's salary increases by $10,000 but he has to repay $2,000 for his loan. Therefore, he ends up with an extra $8,000 per year.
Explanation:Mitch receives a 25% increase on his previous pay of $40,000 which equates to an additional $10,000 for the year (25% of $40,000 is $10,000), giving him a new salary of $50,000.
However, Mitch must pay 4% of his new salary towards his Study Assist loan. 4% of $50,000 equals $2,000. So he must repay $2,000 for his loan.
Therefore, the extra pay that Mitch actually keeps after paying his loan is $10,000 (rise in salary) minus $2,000 (loan repayment) which is $8,000 for the year. He ends up with $8,000 extra compared to his initial salary.

the state fair is a popular field trip destination. This year the señior class at High school A and the señior class at High school B both planned trips there the señior class A rented and filled 8 vans and 8 buses with 240 students. High school B rented and filled 4 vans and 1 bus with 54 students. every van had the same number of students in it as did the buses. find the number of students in each van and each bus
Answer:
The number of student in each van is 8. The number of student in each bus is 22.
Step-by-step explanation:
Consider the provided information.
Let the number of student in each van is x.
The number of student in each bus is y.
School A rented and filled 8 vans and 8 buses with 240 students.
This can be written as:
[tex]8x+8y=240[/tex]......(1)
School B rented and filled 4 vans and 1 bus with 54 students.
[tex]4x+y=54[/tex]
[tex]y=54-4x[/tex]......(2)
Substitute the value of y in equation (1).
[tex]8x+8(54-4x)=240[/tex]
[tex]8x+432-32x=240[/tex]
[tex]8x-32x=240-432[/tex]
[tex]24x=192[/tex]
[tex]x=8[/tex]
Thus, the number of student in each van is 8.
Substitute the value of x in equation (2).
[tex]y=54-4(8)[/tex]
[tex]y=54-32[/tex]
[tex]y=22[/tex]
Thus, the number of student in each bus is 22.

Answer:
[tex]-9\sqrt{11}[/tex]; None of the above; [tex]3\sqrt{7}[/tex]
Step-by-step explanation:
For the first question:
[tex]5\sqrt{11}-12\sqrt{11}-2\sqrt{11}[/tex]
Treating the radicals as a variable, we combine like terms:
[tex]5\sqrt{11}-12\sqrt{11}-2\sqrt{11}\\\\=-7\sqrt{11}-2\sqrt{11}\\\\-9\sqrt{11}[/tex]
For the second question:
[tex]5(10-4\sqrt{2})[/tex]
We use the distributive property:
[tex]5(10-4\sqrt{2})\\\\5\times 10-5\times4\sqrt{2}\\\\50-20\sqrt{2}[/tex]
This is not one of the choices available.
For the third question:
[tex]\sqrt{3}\times \sqrt{21}[/tex]
We will first find the prime factorization of 21. 21 = 3*7:
[tex]\sqrt{3}\times \sqrt{3\times7}[/tex]
These can all be written under one radical:
[tex]\sqrt{3\times 3\times 7}[/tex]
For square roots, we want pairs of factors. We have a pair of 3s, so this comes out, giving us
[tex]3\sqrt{7}[/tex]

In other words, 50 minus 20 square root of 2.
Thus, Option fourth is correct.
In third question, given expression,
√3×√21,
And we can write, √3×√21=√3×√3×√7=3√7
Thus, third option is correct.
