What is the area of the composite shape?
Answer:
292 sq yd
Step-by-step explanation:
I believe you can multiply 26 x 29 and then subtract 21 x 22 from that
26 x 29 = 754
21 x 22 = 462
754 - 462 = 292

Step-by-step explanation:
B's numbers are all doubled of what they are on the original.
Answer:
B
Step-by-step explanation:
First of all the angle is same
and then we check if ratios of all sides are equal so
5/10=6/12=12/24=7/14
1/2=1/2=1/2=1/2
the ratios are equal so the shapes are similar

Step-by-step explanation:
The formula is y=mx+b, so whatever number is in the b spot that is your intercept and where you start and the slope is rise/run so that is how many times you move. Hope this helps:)
what is the base if the height is 6ft and the area is 14 ft on a triangle
Answer:
b = 4.66666667
Step-by-step explanation:
The equation for finding the area of a triangle is
0.5b x h = a
b = base
h = height
a = area
So I calculated 14 divided by 6
And got 2.3333333
And since that number is half of the base, I multiplied it by 2
2.333 x 2 ≈ 4.66666667

The area of a regular hexagon inscribed in a circle with radius 2 is . Round your answer to the nearest tenth.
Answer:
10.4 to nearest tenth.
Step-by-step explanation:
If we draw lines from the centre of the circle to each vertex of the hexagon we get 6 equilateral triangles of side length 2.
Altitude of each triangle = sqrt(2^2 - 1^2)
= sqrt3.
So the area of 1 triangle = 1/2 * 2 * sqrt3
= sqrt3
Therefore the area of the hexagon = 6 * sqrt3
= 6sqrt3
= 10.3923

Two functions are graphed on the coordinate plane.
On a coordinate plane, a curved line with an upward arc, labeled g of x, crosses the x-axis at (negative 2, 0), and the y-axis at (0, 4). A straight horizontal line, labeled f of x, crosses the y-axis at (0, 4).
Which represents where f(x) = g(x)?
f(4) = g(4) and f(0) = g(0)
f(–4) = g(–4) and f(0) = g(0)
f(–4) = g(–2) and f(4) = g(4)
f(0) = g(–4) and f(4) = g(–2)
Answer:
Answer:
(B) f(-4)=g(-4) and f(0)=g(0)
Step-by-step explanation:
From the given graph, the lines f(x) and g(x) intersects at two different points.
When x=-4, f(-4)=4 and g(-4)=4
When x=0, f(0)=4 and g(0)=4
Therefore, the points which represent where f(x)=g(x) are:
f(-4)=g(-4); and
f(0)=g(0)
The correct option is B.

replace for the known values c and a to find b
The required length of AC is 8 unit.
What is a right angle triangle?A right-angled triangle is a triangle, that has one of its interior angles equal to 90 degrees.
Given that,
In triangle ABC, angle C is a right angle,
Also side AB = 17, BC = 15 and AC =?
To find side AC, use Pythagoreans theorem,
AB² = BC² + AC²
Substitute the values of AB and BC,
17² = 15² + AC²
289 = 225 + AC²
⇒AC² = 289 - 225
⇒AC² = 64
⇒AC = 8
The required length of AC is 8 unit.

Find the measure of the exterior angle.
Answer: 108 degrees
Step-by-step explanation:
An exterior angle of a triangle is equal to the sum of the two remote interior angles. (Remote referring to the farthest angles from the exterior angle) 2a = (a+10) + 44. Combine like terms.
2a = a+ 54. Subtract “a” from both sides.
a= 54
You can check for correctness by plugging in 54 for a. 2(54) = (54+ 10) + 44. 108= 108.
(Remember, the exterior angle should equal the sum of the two remote interior angles)

Nayeli wants to earn some extra money so she sells lemonade for $2 per cup and orange juice for $3 per cup. She sells a total of 100 cups and earns $240. Later she wants to find the number of cups of lemonade and the number of cups of orange juice she sold. Which system of equations below represents this situation?
1. 2x + 3y = 240 AND x + y = 100
2. 2x + 3y = 100 AND x + y = 240
3. x + 2y = 100 AND 3x + y = 240
4. 2x + 100 = 240.AND x = 3y
Answer:
1
Step-by-step explanation:
let x represent lemonade and y represent orange juice
the total earning is $240. 2x+3y=240 allows you to find the number of each cup you need to sell to get $240.
the total number of cups sold is 100. x+y=100 gives you the other equation necessary to find the number of cups of each sold if you told a total of 100

Expand parenthesis
6x+8-2x=24
Combine like terms
4x+8=24
Subtract 8 on both sides
4x+8-8=24-8
4x=16
Divide 4 on both sides
