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

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.

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.

Please help!!!! The roots of x^2-2x-2=0 are A.1+square root of 3 B.1+square root of 12 or C.No real roots
Answer:
A
Step-by-step explanation:
We have the equation:
[tex]x^2-2x-2=0[/tex]
We can use the quadratic formula. In this case, a = 1, b = -2, and c = -2. Hence:
[tex]\displaystyle x=\frac{-(-2)\pm\sqrt{(-2)^2-4(1)(-2)}}{2(1)}[/tex]
Evaluate:
[tex]\displaystyle x=\frac{2\pm\sqrt{12}}{2}[/tex]
Simplify:
[tex]\sqrt{12}=\sqrt{4}\cdot\sqrt{3}=2\sqrt{3}[/tex]
Hence:
[tex]\displaystyle x=\frac{2\pm2\sqrt{3}}{2}[/tex]
Divide:
[tex]x=1\pm\sqrt3[/tex]
The correct answer is A.
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
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]

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.

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
simplify the product.
[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]

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
