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?
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.

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.

3 hours worked for$12;9 hours worked for $36
This answer explains the concept of Labor Economics and Wages by calculating the hourly rate from given total pay and total hours worked.
Explanation:The subject of this question involves Labor Economics and Wages.
In this scenario, the wage for working 3 hours is $12, while for working 9 hours, the pay is $36. To determine the hourly rate, we can use the formula: Hourly Rate = Total Pay / Total Hours Worked. Applying this formula, we find the hourly rate to be $4 per hour.
Example:
3 hours worked for $12 -> Hourly rate = $12 / 3 hours = $4 per hour9 hours worked for $36 -> Hourly rate = $36 / 9 hours = $4 per hourMeredith lives 24 blocks from her friends house. she travels 1 block per minute. What if she travels 2 blocks per minute? how many blocks would it take her to get to her friends house?

Assume that the sales of a certain appliance dealer are approximated by a linear function. Suppose that sales were $14,500 in 1982 and $65,500 in 1987. Let x = 0 represent 1982. Find the equation giving yearly sales S
Final answer:
To articulate the linear equation for yearly sales S, we calculate the slope from the two provided data points and use the slope-intercept form, ultimately deriving the equation S = 10200x + 14500.
Explanation:
To find the equation giving yearly sales S, we can use the two data points: sales were $14,500 in 1982 and $65,500 in 1987. With x = 0 representing 1982, the two points are (0, 14500) and (5, 65500). We can calculate the slope (m) using the formula m = (y2 - y1) / (x2 - x1), which is the change in sales over the change in time.
So, m = (65500 - 14500) / (5 - 0) = 51000 / 5 = 10200. This means the sales are increasing at a rate of $10,200 per year.
Now, we can use the slope and one point to write the linear equation in the slope-intercept form, which is Y = mx + b, where b is the y-intercept. Since when x = 0, Y = 14500, we know that b = 14500. Therefore, our final equation for yearly sales S is S = 10200x + 14500.
a metallurgist has an alloy with 10% titanium and an alloy with 20% titanium. he needs 100 grams of an alloy with 17% titanium. how much of each alloy should be mixed to attain the 100 grams of alloy with 17% titanium?
Let us say that:
x = mass of 10% titanium alloy required
y = mass of 20% titanium alloy required
To solve this problem, we set-up two mass balances or equations.
Overall mass balance: x + y = 100
x = 100 – y ---> 1
Titanium mass balance: 0.10 x + 0.20 y = 0.17 (100)
0.10 x + 0.20 y = 17 ---> 2
Now we combine equations 1 and 2:
0.10 (100 – y) + 0.20 y = 17
10 – 0.10 y + 0.20 y = 17
0.10 y = 7
y = 70 g
Calculating for x using equation 1:
x = 100 – y
x = 100 – 70
x = 30 g
Answer:
x = 30 g of 10% titanium alloy required
y = 70 g of 20% titanium alloy required
Suppose that (x1, y1) and (x2, y2) are two points on a linear function. Write the formula to find the function’s rate of change for the interval [x1, x2].
Final answer:
The rate of change for a linear function on the interval [x1, x2] is the slope of the line m, calculated by dividing the difference in y-values by the difference in x-values: m = (y2 - y1) / (x2 - x1).
Explanation:
To find the rate of change of a linear function for the interval [x1, x2], we need to calculate the slope of the line connecting the points (x1, y1) and (x2, y2). This is done using the formula:
m = (y2 - y1) / (x2 - x1)
where m represents the slope, which is the ratio between the change in y-values (rise) and the change in x-values (run). When graphing the function, if you plotted these two points, you'd be able to draw a straight line between them, and by finding the slope, you determine how steep the line is. The slope, or rate of change, indicates how much y increases or decreases for each unit increase in x. This rate of change is constant along the entire length of a straight line.
