Circle M dilated by a scale factor of 3 gives circle N. If the circumference of circle N is 6 cm, what is the circumference of circle M?
A.
54 cm
B.
3 cm
C.
2 cm
D.
18 cm
Answers
Step-by-step explanation:
2 cm
scale factor of 3
then 6/3 = 2 cm
Answer:
C. 2 cm
Step-by-step explanation:
As the circumference is a measure of length (one dimension), we can simply divide the given circumference of circle N by the scale factor to find the circumference of circle M:
⇒ circumference of circle M = circumference of circle N ÷ scale factor
= 6 cm ÷ 3
= 2 cm
(If we were working with area, we would have to divide/multiply by the square of the scale factor, since we would be working in 2 dimensions)

The sum of two numbers is 87. The difference of the same to numbers is negative 111. Find the numbers.
Answers
Answer:
99 and - 12
Step-by-step explanation:
let x and y be the 2 numbers, then
x + y = 87 → (1)
x - y = - 111 → (2)
Adding the 2 equations term by term eliminates the y- term
2x = - 24 ( divide both sides by 2 )
x = - 12
Substitute x = - 12 into (1)
- 12 + y = 87 ( add 12 to both sides )
y = 99
The 2 numbers are 99 and - 12

Your cafeteria line requires 8 minutes on the average for each customer to proceed through the line and pay the cashier. The average time space between each customer is 30 seconds. If the line is open for 1 1/2 hours for lunch, how many customers can you serve for lunch?
Answers
Answer:
You can serve 81 customers for lunch during the 11,5 hours opening.
Step-by-step explanation:
11,5 hours is 690 minutes.
Each customer takes 8,5 minutes (8 + 0,5)
690 / 8,5 = 81,17
As we can't serve "part" of customer:

Does AN time E equal to ABN if A=1, B=5, E=3 & N=0?
Answers
Answer:
Yes, AN time E equal to ABN if A=1, B=5, E=3 & N=0.
Step-by-step explanation:
Given;
Does AN time E equal to ABN if A=1, B=5, E=3 & N=0?
A = 1
B = 5
E = 3
N = 0
Note;
0 multiply everything is 0.
Solve;
So If A=1, B=5, E = 3, N=0
AN times E = (1 x 0) x 3 = 0
ABN = (1 x 5 x 0) = 0
Therefore, the question would be true.

A scientist measures the velocity of a major river at various depths. After collecting and analyzing the data, the scientist determines that the equation y=−0.114x+1.658, where x represents the depth, in feet, and y represents the velocity of the river, in feet per second, can be used to model the data. The linear model has a correlation coefficient of 0.964.
Answers
Answer:
If you translate that in romanian i will do it.
The velocity of a major river at various depths has no relation.
What is a linear equation?A linear equation is an equation that has the variable of the highest power of 1. The standard form of a linear equation is of the form Ax + B = 0.
We are given that;
Equation y=−0.114x+1.658
Now,
In this case, the equation y = -0.114x + 1.658 represents a linear relationship between x (depth) and y (velocity) of the river. The correlation coefficient is 0.964, which means there is a very strong positive correlation between these two variables. This means that as depth increases, velocity also tends to increase proportionally.
| x | y |
| 0 | 1.658 |
| 5 | 1.098 |
|10 | 0.538 |
|15 |-0.022 |
The calculator gives us a p-value of approximately 0.0002, which is much smaller than 0.05. This means that we can reject the null hypothesis that there is no correlation between depth and velocity of the river and conclude that there is a statistically significant positive correlation between them.
Therefore, by the given equation there will be no relation.

Answers
A hotel has a rectangular shaped meeting room that is 13.4 yards wide and 15.1 yards long. If the carpenter cost $ 1.71 per feet² what would be the cost of carpenting the room ?
✯ Explanation -Given :
Length of the meeting room = 15.1 yardBreadth of the meeting room = 13.4 yardRate of carpenting per feet² = $ 1.71Need to find :
Cost of carpenting the room.Solution :
THIS QUESTION IS BASED ON MEANSURATION TO SOLVE THIS QUESTION FIRST WE WILL CALCULATE THE AREA OF THE MEETING ROOM AND THEN WE WILL CALCULATE THE COST OF CARPENTING THE MEETING ROOM.
Calculating the area of the meeting room
[tex] \star \: \large \boxed{\sf{ Area_{(rectangle)} = Length × Breadth }}[/tex]
[tex] \large\rm{ Area_{(rectangle)} = (15.1 × 13.4) yard² = 202.34 \: yards²}[/tex]
Area of the meeting room = 202.34 yard²
Calculating the cost of carpenting the meeting room
First we will convert yards into feet
We know,
1 yard = 3 feet
202.34 yard = 202.34 × 3 = 607.02 feet
Now calculating the cost of carpenting the meeting room
Rate of carpenting = $ 17.1 per feet²
Cost of carpenting = $ ( 17.1 × 607.02) = $10,380.04
Final Answer -
Cost of carpenting the meeting room = $10,380.04.[tex] \rule{180pt}{3pt}[/tex]

[tex]a[/tex] is the length of the top side[tex]b[/tex] is the length of the bottom side[tex]h[/tex] is the height (forms a right angle with the bottom of the trapezoid)Solving the QuestionQuestion 2We're given:
Volume of the cube = 343 cm³We must solve for the surface areaFirst, use the volume formula to solve for the side length:
[tex]V=a^3[/tex]
⇒ Plug in the known volume:
[tex]343=a^3\\\sqrt[3]{343}=\sqrt[3]{a^3}\\a=7[/tex]
Therefore, [tex]a=7[/tex].
Now, plug this value into the formula for surface area:

⇒ Plug in the given information:
[tex]A=\dfrac{1}{2}(14+24)(16.5)\\\\A=\dfrac{1}{2}(38)(16.5)\\\\A=(19)(16.5)\\A=313.5[/tex]
Therefore, the area of the trapezoid is 313.5 ft²
Multiply it by 2:
[tex]313.5*2\\=627[/tex]
Divide this by 72:
[tex]\dfrac{627}{72}\\\\=8.7[/tex]
Therefore, we need 9 cans of paint to paint two coats over the deck.

The solution of the linear equations y = -x + 3 and y = 4x - 2 will be (1, 2). Then the correct option is B.
What is the solution to the equation?The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.
A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.
The linear equations are given below.
y = -x + 3 ...1
y = 4x - 2 ...2
From equations 1 and 2, then we have
4x - 2 = - x + 3
4x + x = 2 + 3
5x = 5
x = 1
Then the value of 'y' is given as,
y = - 1 + 3
y = 2
The solution of the linear equations y = -x + 3 and y = 4x - 2 will be (1, 2). Then the correct option is B.
