Answer:
112π ≈ 351.9 square units
Step-by-step explanation:
Assuming the smaller circle is wholly contained within the larger circle, the difference of their areas is ...
ΔA = (π·11²) -(π·3²) = π·(121 -9) = 112π ≈ 351.9 . . . square units
__
The formula for the area of a circle is ...
A = πr²
The point-slope equation of a line is
O A. y+ X- XV0 = m
O B. y= m(x-yo)
O C. y+ mx - mxoyo
O D. y-yo = m(x - xo)
Answer:
D. [tex] y - y_0 = m(x - x_0) [/tex].
Step-by-step explanation:
The equation of a line can be written in the point-slope form if we know the the coordinates of a point the line passes through which is [tex] (x_0, y_0) [/tex]. And if we also know the slope = m of the line.
Therefore, the point-slope equation is given as:
[tex] y - y_0 = m(x - x_0) [/tex]

All but 6 of the 25 students in my 6th grade math class play spring sports.
What percent of the students do not play spring sports?
Answer: 24% of students
Step-by-step explanation:
6 students divided by 25 total students = 0.24. You would multiply 0.24 by 100 or move the decimal two places to the right to get the percentage. In this case, the percentage would be 24%. 24% of students do not play spring sports.
[tex]6/25 = 0.24 *100 = 24 percent[/tex]

A student purchased a used car for $5,000. Three months later, the student discovers the car needs major repairs which will cost $2,000. The student must decide whether to repair the car or purchase another car. Which statement is correct?
Answer:
The relevants cost are $2,000
Step-by-step explanation:
Based on the information given in a situation where the student have to decide whether to repair the car or purchase another car the correct statement is: THE RELEVANTS COST ARE $2,000 because the cost of repairs of the Amount of $2,000 represent the RELEVANT COST.
Therefore RELEVANT COSTS are costs or expense that can be incurred due to some certain decisions and on the other hand RELEVANT COSTS which is also known as AVOIDABLE COST can be seen as the cost or expense a person or an individual can do away with depending on other alternative such person choose to pick.

126,349 rounded to the hundred place
Answer:
126,300.
Step-by-step explanation:
Answer:
Your answer would be 126,350!
Step-by-step explanation: Since the ones place is directly beside the hundreds place to the right, you would use this number to determine whether you stay or round up. 9 is greater then 5, meaning you round up making the hundreds place a 5. Hope this helps! :)

How many solutions does the equation have? 7x +3 - x=3(1 + 2x) (A) 0 (B) 1. (C) infinitely many
Answer:
C) Infinitely many
Step-by-step explanation:
7x+3-x=3(1+2x)
6x+3=3+6x
Subtract 3 from both sides
6x = 6x
Infinitely many solutions

A company owns two stores and recorded data for the number of days missed by employees.
Store 1. 1, 2, 1, 1, 0, 4, 2, 0, 0
Store 2. 1, 0, 1, 1, 0, 4, 9, 1.
Select true or false for each statement.
Based on the median, typically employees missed more days at Store 2 than at Store 1
The median number of days missed by employees at Store 2 is 0.5
The number of days missed by employees at Store 1 ranged from 0 to 4
Answer:
a) false, median is 1 for each store
b) false, median at store 2 is 1

Find the value of X and Y that make these triangles congruent by the HL theorem.
Answer:
x=5, y=6
Step-by-step explanation:
By the HL theorem, if the corresponding hypotenuses and one side of two triangles are equal, they are congruent.
So put the hypotenuses equal to each other, and put the side lengths equal to each other.
3x-2=2y+1
x=y-1
Sub 'y-1' into the first equation for x:
3(y-1)-2=2y+1
3y-3-2=2y+1
y=6
x=y-1=6-1=5
Can someone please help me i will mark u brilliant
Answer:
11
Step-by-step explanation:
The line plot shows how many people read many many books with the number of "x"s above each number. So, through this graph, we see that 0 people read 0 books, 5 people read 1 book, 3 people read 2 books, 6 people read 3 books, 3 people read 4 books, 3 people read 5 books, 2 people read 6 books, 2 people read 7 books, and 1 person read 8 books. The problem asks how many people read 4 or more books. So, we add up all the people that read 4 or more books shown on the graph, which is 4, 5, 6, 7, and 8.
3 people read 4 books, 3 people read 5 books, 2 people read 6 books, 2 people read 7 books, and 1 person read 8 books.
3 + 3 + 2 + 2 + 1 = 11. 11 students read 4+ books.
What is the slope-intercept equation of the line below? y-intercept=(0,2) slop=-1/4
Answer:
y=-1/4x+2
Step-by-step explanation:
So the forumla for slope/intercept equation is:
y=mx+b
Y equals the y coordinates on the graph. This is the value that you plug in x to solve for.
m equals the slope of the graph. (In this case -1/4)
x equals the x coordinates. This will always be just x when writen in a slope intercept equation, since x is the value you plug in to solve for y.
b equals the y intercept. This is different from the y coordinates. This is a known value, which can be found when x=0. (In this case 2)
Now, using this lets plug in our numbers for the differet variables:
y=mx+b
We know that m, the slope, is -1/4. So:
y=-1/4x+b
We also know that b, the y inteercept, is 2. Since we have the coordiantes (0x, 2y). So:
y=-1/4x+2
This is all you have to do! This is because y is the number you solve for, and x is the value you plug.
Hope this makes sense and helps! :)
What is 12.4 inches in millimeters
What is 23.1 inches in millimeters
Answer:
314.96
586.74
Step-by-step explanation:
Answer:314.96; 586.74
Step-by-step explanation:
1 inch = 25.4 millimeters
12.4 x 25.4 = 314.96
23.1 x 25.4 = 586.74
Multiply the number of inches by 25.4 to convert to millimeters :).
Find the volume of the solid
Answer:
552
Step-by-step explanation:
Answer:
V = 552 mm^3
Step-by-step explanation:
To find the volume of a prism, you multiply the base and the height. We can write an equation to model the situation:
V = Bh
Where V is the volume, B is the base, and h is the height.
We can substitute the values we have:
V = 92 x 6
V = 552 mm^3
