If a chord of a circle is 6 and is twice as far from the center chord of length 12, how long is the radius of the circle?
Answer and explanation:
A center chord in a circle is the diameter of that circle. Therefore a center chord of a circle is different from other chords that touch two points on the circle but not in the center of the circle. A diameter of a circle is the chord that runs the length of the center of the circle touching two points at the edge of the circle. A diameter is twice the radius of the circle. So if the diameter of the circle is 12cm then the radius of the circle is 6cm

PLEASE HELP ITS DUE SOIN AND I DONT KNOW HOW TO ANSWER
Answer:
y = - 3
Step-by-step explanation:
Given the 2 equations
6x + 11y = - 3 → (1)
4x + y = = 17 → (2)
Multiplying (1) by 4 and (2) by - 6, then adding will eliminate the term in x
24x + 44y = - 12 → (3)
- 24x - 6y = - 102 → (4)
add (3) and (4) term by term to eliminate x
0 + 38y = - 114
38y = - 114 ( divide both sides by 38 )
y = - 3

Answer:
The ordered pair (15, 12) means that 15 pounds of beans cost $12.
Step-by-step explanation:
(20, 16)
(x, y)
x is along the x-axis and y is along the y-axis.
x = 20 = 20 pounds of beans
y = 16 = 16 is the cost of the beans
(15, 12)
x = 15 is 15 pounds of beans
y = 12 is 12 for the cost of the beans
Answer: 15 pounds of beans costs 12 dollars
Step-by-step explanation:
if the x-axis represents the pounds of beans, then any x-coordinate will be beans.
In 2010, the population of a city was 168,000. From 2010 to 2015, the population grew by 8%. From 2015 to 2020, it fell by 5%. To the nearest 100 people, what was the population in 2020?
Answer:
172000
Step-by-step explanation:
Population growth from 2010 to 2015 if population increased by 8% =
1.08 x 168,000. = 181440
Population growth from 2015 to 2020 if population decreased by 5% =
0.95 x 181440 = 172,368
Rounding off to the nearest 100 people = 172,000
The population in the year 2020 is 172,368.
Calculation of the population in 2020:Since
In 2010, the population of a city was 168,000. From 2010 to 2015, the population grew by 8%. From 2015 to 2020, it fell by 5%.
So,
[tex]= 168000 \times 1.08 \times 0.95[/tex]
= 172,368
hence, The population in the year 2020 is 172,368.

A movie theater sells out 7 times per month. Chloe counted 168 sellouts at the theater. How long was Chloe recording sales?
A. 7 years
B. 2 years
C. 1 year
D. 24 years
More questions will be asked in the comments
Answer:
B. 2 years
Step-by-step explanation:
use y = mx + b
y = total number of sell outs = 168
m = sell outs per month = 7
x = months
b is not needed for this
168 = 7x
divide both sides by 7
x = 24
divide 24 by 12 to get the number of years
years = 2
Answer:
the answer to this question is B. 2 years

100 100
8075/100= 80.75
85-80.75=4.25
Given that triangle LMN is
similar to triangle GJH, what is
the value of x?
Answer:
x = 53
Step-by-step explanation:
Similar means that the corresponding angles are congruent (the same) - basically what this means is that ∠L ≅ ∠G, ∠M ≅ ∠J, and ∠N ≅ ∠H.
Since we know that the angle measures in a triangle should add up to 180 and we know the measures of ∠L and ∠M already, we can do
180 = 67 + 60 + N
So, N = 180 - (67 + 60) = 180 - 127 = 53.
Since ∠N ≅ ∠H, ∠H = 53.

How do I solve the triangles ?
Answer:
I'm so sorry I only found the area of the first triangle with the measurements 11, 10 and 17
I'll show you how to find the area
Step-by-step explanation:
The formula for a triangle is base x height divided by 1/2
For the first triangle the base is 11 and the height is 10
base(11) x height(10) = 110 then divide 110 by 1/2 = 55
so the area of the first triangle is 55.
Sorry again this is only the area of the first triangle.

[tex]10\sqrt{12x^{3} } . 2\sqrt{6x^{5} }[/tex]
full calculations please!!
Answer:
[tex]120x^4\sqrt{2}[/tex]
Step-by-step explanation:
First we need to break down the numbers in the radicals into its factors
so
12= 3*2*2
x³=x*x*x
Which means we have
[tex]10\sqrt{3*2*2*x*x*x}=20x\sqrt{3x}[/tex]
and
[tex]2\sqrt{2*3*x*x*x*x*x} =2x^{2} \sqrt{6x}[/tex]
Because the radicand (the small number that goes up top) are the same we can just mulitply the two from here
which means we have
[tex](20x*2x^2)\sqrt{3x*6x}=40x^3\sqrt{18x^2} \\\sqrt{18x^2}=\sqrt{2*3*3*x*x} =3x\sqrt{2} \\=120x^4\sqrt{2}[/tex]

Answer: Area 89m^2
Step-by-step explanation:
To find the area of the rectangle we multiply
Base * Height = Area
8 * 13 = 104
Now we find the area that isn't shaded
I inference that the base of the triangle is 5m
5 * 6 = 30
Now divide that by 2
30/2 = 15
Subtract 15 from 104
104 - 15 = 89m^2
