Circumference of circle = 2πr
Putting values ::-
37.7 = 2 × 3.14 × r
r = 37.7 ÷ 6.28
r = 6.003 (approx)
therefore,
d = r × 2 = 6.003 × 2
d = 12.006

What is the image point of (0, 8) after a translation right units and down 5 units?
Answer:
(5,3)
Step-by-step explanation:
1. Translation 5 units right, so the x-coordinates goes to 5.
2. Translation 5 units under, so the y-coordinates goes to 3.
So . the answer is (5, 3)

2 1 -5 4 3 2 -11 2 4 5 X -2 ب ا -5 a Write down the gradient of the graph.
Answer:
Gradient = -3
Step-by-step explanation:
The gradient of the graph = change in y/change in x
Change in y = the vertical distance = 3 units
Change in x = the run/horizontal distance = 1 unit
The line slopes downward, so it's a negative gradient.
Thus:
Gradient = 3/1 = -3

Which statement about the equation 3x ^ 2 + 9x - 12 = 0 is true ? 1 . The product of the roots is -12 . 2 The product of the roots is -4 . 3 The sum of the roots is 3 . The sum of the roots is -9 .
Answer:
Option : The product of the roots is - 4
Step-by-step explanation:
[tex]3x^2 + 9x - 12 = 0\\\\3x^2 + 12x - 3x - 12 = 0\\\\3x(x+4) -3(x+4) = 0\\\\(3x - 3) (x+ 4) = 0\\\\[/tex]
Therefore the roots are -4 and 1
The product of the roots are -4 x 1 = -4

b) Show that the points (1,1), (-1,-1) and ( -root3, root 3 ) are the vertices of an equilateral triangle.
Given:
The vertices of a triangle are [tex](1,1),(-1,-1),(-\sqrt{3},\sqrt{3})[/tex].
To prove:
The given vertices are the vertices of an equilateral triangle.
Solution:
Distance formula:
[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Let the vertices of the triangle are [tex]A(1,1),B(-1,-1),C(-\sqrt{3},\sqrt{3})[/tex]. Then, by using the distance formula, we get
[tex]AB=\sqrt{(-1-1)^2+(-1-1)^2}[/tex]
[tex]AB=\sqrt{(-2)^2+(-2)^2}[/tex]
[tex]AB=\sqrt{4+4}[/tex]
[tex]AB=\sqrt{8}[/tex]
Similarly,
[tex]BC=\sqrt{(-\sqrt{3}-(-1))^2+(\sqrt{3}-(-1))^2}[/tex]
[tex]BC=\sqrt{(1-\sqrt{3})^2+(1+\sqrt{3})^2}[/tex]
[tex]BC=\sqrt{(1)^2+(\sqrt{3})^2-2\sqrt{3}+(1)^2+(\sqrt{3})^2+2\sqrt{3}}[/tex]
[tex]BC=\sqrt{1+3+1+3}[/tex]
[tex]BC=\sqrt{8}[/tex]
And,
[tex]CA=\sqrt{(1-(-\sqrt{3}))^2+(1-\sqrt{3})^2}[/tex]
[tex]CA=\sqrt{(1+\sqrt{3}))^2+(1-\sqrt{3})^2}[/tex]
[tex]CA=\sqrt{(1)^2+(\sqrt{3})^2+2\sqrt{3}+(1)^2+(\sqrt{3})^2-2\sqrt{3}}[/tex]
[tex]CA=\sqrt{1+3+1+3}[/tex]
[tex]CA=\sqrt{8}[/tex]
Clearly, [tex]AB=BC=CA[/tex].
Since all sides of the given triangle are equal, therefore the given vertices are the vertices of an equilateral triangle.
Hence proved.
Charlie withdraws cash from an ATM that is not his own bank’s 3 times a month. He pays $1.50 per transaction. If this pattern is consistent across a year, what will his yearly cost be?
Answer:
If I understand this right, the answer is $48.00
Step-by-step explanation:
If they pay $1.50 three times a month just times $1.50 by 12 because there are 12 days in a month, then you get 16, then you times 16 by 3 and you get 48.
(I hope this is right lol)
Answer:
$54.00
Step-by-step explanation:
3 transactions × $1.50 per transaction = $4.50 per month
$4.50 × 12 months in a year = $54.00

Of the marbles in a bag, 4 are yellow , 4 are white , and 5 are green . Sandra will randomly choose one marble from the bag. Fill in the blanks in parts a and b. The probability that Sandra will choose a marble from the bag is
Answer:
Probability[Random choose marble is green] = 5 / 13
Step-by-step explanation:
Given:
Number of yellow marble in bag = 4
Number of white marble in bag = 4
Number of green marble in bag = 5
Find:
Probability[Random choose marble is green]
Computation:
Probability of an event = Number of favourable outcome / Number of total outcome
Probability[Random choose marble is green] = 5 / [4 + 4 + 5]
Probability[Random choose marble is green] = 5 / 13

Answer:1) 32. 2). 3) 21. 4) 4
Step-by-step explanation: 1) 4*8=32m, 2) I don't know, 3) 6*7=42 for the area of a square but since a triangle half it so its 21, An the last is by 4 for example 4*10=40 but if doubled its 20*8 and that equals 160. and 160/40=4
Find the length of the hypotenuse to the nearest tenth. (example 4.5)
7
2

Answer:
hypotenuse = 7.3
Step-by-step explanation:
the length two legs of the given triangle are 7 and 2 respectively.
using pythagoras theorem
a^2 + b^2 = c^2
7^2 + 2^2 = c^2
49 + 4 = c^2
53 = c^2
[tex]\sqrt{53}[/tex] = c
7.3 = c
Put these numbers in order from least to greatest.
0.48,0.73, and 3/10
Answer:
[tex]\frac{3}{10} , 0.48 , 0.73[/tex]
Step-by-step explanation:
In order to put this number in order from least to greatest, we have to turn them into fractions with the same denominator, so firstly we write down all of the decimals as fractions, and we will get...
[tex]0.48 = \frac{48}{100} \\\\0.73 = \frac{73}{100}[/tex]
Now, we need to find the smallest number that is divisible by 100 and by 10, and this number will be the least common denominator. The smallest number that is divisible by 100 and by 10 is 100, therefore 100 is the least common denominator. Now we have to make all of the fractions have the denominator of 100 and we do that in the following way...
[tex]\frac{48}{100}= \frac{48}{100}\\\\\frac{73}{100} = \frac{73}{100}\\\\\frac{3}{10} = \frac{(3)(10)}{(10)(10)} = \frac{30}{100}[/tex]
By looking at this we need to understand that...
[tex]\frac{30}{100}<\frac{48}{100}<\frac{73}{100}[/tex]
Therefore...
[tex]\frac{3}{10} < 0.48 < 0.73[/tex]

Answer: 103 degrees
Step-by-step explanation: all angle of a regular triangle always add up to 180. so 62+15=77. and 180 - 77= 103
Answer:
A. 103 degrees
Step-by-step explanation:
In a triangle, the sum of angle measures is equal to 180 degrees, so by adding 62 & 15, & subtracting it from 180 you get the third angle measure of 103.

What is a Circle ?A circle is a round shaped figure , whose all points are in the same plane and at same distance from a single point known as center.
A secant is a segment that passes through 2 points on a circle, It is an infinite extension of a chord.
A tangent touches a circle at exactly one point and never enters the interior of the circle.
A chord is a line segment which connects two point on the circle.
A diameter is a chord that passes through the center of the circleThe radius is half of the diameter of the circle

Ryan is cleaning out his room. His sister gives him 4 boxes of books to put with the 3 books he already had. When he finishes cleaning he discovers he now has 35 books on his shelves. How many books were in each box? Write an algebraic expression to represent this problem then solve.
Answer:
8 books were in each box
Step-by-step explanation:
According to the Question,
Assume X is the Number of Books In Each Box.
We have, 4 boxes With the Same Number of Books In each Box,Thus Total Book in all box is 4X.And, 3 books Ryan Already Put In Shelves.Now, Total Number Of Book After Cleaning is 35 Books.Algebraic Expression,
4X + 3 = 35
4X = 35 - 3
4X = 32 ⇔ X=8 books in Each Box.
