How to get an area for this shape
Answer:
A = 135 cm²
Step-by-step explanation:
The figure is composed of 2 triangles.
The area (A) of a triangle is calculated as
A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the perpendicular height )
The total area is the sum of the area of both triangles
A = [tex]\frac{1}{2}[/tex] × 18 × 7 + [tex]\frac{1}{2}[/tex] × 18 × 8
= 9 × 7 + 9 × 8
= 63 + 72
= 135 cm²
A Taste Test ask people from Texas and California which pasta they prefer, brand A or brand B. This table shows the results.

I need help with a and b ASAP
Answer:
A is (-3,0) and (1,0).
B is (-1, -2).
Step-by-step explanation:
To find the x-intercepts, look along the x-axis and where the line goes through it. Those two locations are your answer.
To find the vertex, you can find the axis of symmetry by taking its equation and putting it into the form of x = -b/2a or finding the lowest or highest point in the line. In this example, it is (-1, -2) as the lowest point, and there is not a highest point to find, since it is in a u-shape.
Given b=4, c=1, A=120° for a triangle with sides a, b, c and angles A, B, C. What is the area of the triangle? Round to the nearest hundredth.
Answer:
1.73 units
Step-by-step explanation:
The area of a triangle with sides a, b, c and angles A, B, C is given as
Area = 1/2 bc sin A
Given that b=4, c=1, A=120° for a triangle with sides a, b, c and angles A, B, C then the area
= 1/2 * 4 * 1 * sin 120
= 2 sin 120
= 2 * √3/2
= √3
= 1.732
To the nearest hundredth = 1.73

2x + 2y = -2
3x - 2y = 12
Answer:
Answer:
(2,-3)
Step-by-step explanation:
2x + 2y = -2
3x - 2y = 12
Add the two equations to eliminate y
2x + 2y = -2
3x - 2y = 12
-----------------------
5x = 10
5x/5 = 10/5
x = 2
Now find y
2x+2y = -2
2(2)+2y = -2
4+2y = -2
Subtract 4 from each side
4-4 +2y = -2-4
2y = -6
Divide by 2
2y/2 = -6/2
y = -3

A map is drawn with a scale of 1/2 inch equal to 5 actual miles.if the map distance between two cities is 8 inch's,what is the real distance between these cities in miles
Answer:
The real distance would be 16
Step-by-step explanation:
If the scale is 1/2, that means each distance on the map is half of what the real distance is. So 8 x 2 =16.
Answer:
80 miles.
Step-by-step explanation:
Since 1/2 an inch is 5 miles, that would mean one inch is 10 miles. Now that we know one inch is 10 miles, we can multiply 10 x 8 to get 80. Therefore, the real distance between the two citied is 80 miles.

Find the area of the shaded region
Answer:
40
Step-by-step explanation:
area of shaded region = area of whole figure - area of non shaded region
area of whole figure: The whole figure is a rectangle
The area of a rectangle can simply be calculated by multiplying the width by the length
The given width is 10ft and the given length is 8ft
Hence area of whole figure = 10 * 8 = 80ft²
Area of non shaded region: the non shaded region also creates a rectangle
Like stated previously the area of a rectangle can simply be calculated by multiplying the width by the length
The given width is 5ft and the given length is 8ft
Hence, area of non shaded region = 5 * 8 = 40ft²
Finally we can find the area of the shaded region.
We can easily do this my subtracting the area of the nonshaded region from the area of the whole figure
If we have identified that the area of the whole figure is 80 and the area of the non shaded region is 40
Then, area of shaded region = 80 - 40 = 40ft²

A sculpture is made of solid copper in the shape of a cone. The sculpture is 67 inches tall, and its base has a radius of 15 inches. If copper costs 1.06$ per cubic inch, how much did the copper for the sculpture cost?
Use 3.14 for Pi, and do not round your answer.
Answer:
$16,725.21
Step-by-step explanation:
To get the cost of the copper used for the sculpture, we must first determine the volume of the object which is given as a cone
Recall that the volume V of a cone
= 1/3Pir^2h
where r is the base radius and h is the height
Given that the sculpture is 67 inches tall, and its base has a radius of 15 inches, the volume of the sculpture
= 1/3 * 3.14 * 15^2 * 67
= 15,778.5 cubic inch
If copper costs 1.06$ per cubic inch, then the cost of the copper for the sculpture
= 15,778.5 * 1.06
= $16,725.21

Select a Value
(2,6,10,-6,-10)
Part B: The average rate of change between the 4th and 5th point is
Select a Value (6,18,162,-54,-18)
Answer:
6 ; 10
18 ; 162
Step-by-step explanation:
Recall :
Rate of change = Slope = Rise / Run = (y2 - y1) / (x2-x1)
2nd point is (1, 7)
3rd point is (2, 13)
Rate of change = (13 - 7) /(2 - 1) = 6 /1 = 6
3rd and 4th point :
(2, 13)
(3, 23)
Rate of change = (23 - 13) / (3 - 2) = 10 /1 = 10
PART B:
(2, 11) ; (3, 29)
Rate of change = (29 - 11) / (3 - 1) = 18 /1 = 18
(4, 83)
(5, 245)
Rate of change = (245 - 83) / (5-4) = 162 / 1 = 162

If the scale factor between trapezoid ABCD and trapezoid is GHIJ is 2, how many feet will side GJ be?
Kindly find required figure in the picture attached below :
Answer:
14 feets
Step-by-step explanation:
From Trapezoid ABCD ;
The longer base, AD = 7 feets
Shorter Base ; BC = 5 feets
The Trapezoid GHIJ
Shorter Base = HI
Longer base = GJ
Given that the scale factor between ABCD and GHIJ is 2 ; then
GJ is similar to AD
Hence, side GJ = 2 * length of AD
GJ = 2 * 7 = 14 feets
