To find the area of a square it is length times width, meaning 7*7 would make your area for the square. A triangle's area is found by height*base/2. The height in this situation would equal 4, since they are all identical. The base would be 7 since it is next to the square, meaning you would do 7*4 then divide that answer by 2. You can times the answer of that by three since there is three identical triangles and add the area of the square to that and there is your area! Hope this helps, pretty simple to find once you know how. :)
Answer:
(A)T(–2, 4) ry-axis
Step-by-step explanation:
The graph showing triangles MNO and M"N"O" is attached below.
From the graph, the coordinates are:
- M(5,-4),N(3,-2) and O(1,-3)
- M"(-3,0), N"(-1,2) and O"(1,1)
When we <u>transform triangle MNO by (-2,4),</u> we obtain:
M'(3,0), N'(1,2) and O'(-1,1)
Next, we reflect M'N'O' the y-axis.
Note: When you reflect a point across the y-axis, the y-coordinate remains the same, but the x-coordinate is transformed into its opposite.
Therefore:
- Reflection of M'N'O' accross the y-axis gives: M"(-3,0), N"(-1,2) and O"(1,1).
Therefore, the sequence of transformations could be used to map triangle MNO onto M"N"O" is T(–2, 4) ry-axis.
The correct option is A.
Answer:
ayy I gotchuu
Step-by-step explanation:
theres gonna be two solutions
a negative then positive
positive:
|3x - 9| = 12
3x-9=12
3x=21
x=7
negative:
3x-9=-12
3x=-3
x=-1
Answer:
659.4 cm^2
Step-by-step explanation:
The area of the curved surface of the cone = πrL
= π*7*16
= 3.14 * 112
= 351.68 cm^2,
Surface area of the hemisphere = 2 π r^2
= 2*3.14*7^2
= 307.72 cm^2.
Total area = 351.68 + 307.72
= 659.4 cm^2.
The biggest number is 2.4 because if you take 1/2 that's have
