Answer: Dilation
Step-by-step explanation:
Since, in isometry the shape and size does not change after transformation.
In a reflection, rotation and translation the shape and size of a figure is preserved therefore they are isometry while in dilation the size of the figure changes by a scale factor.
( However we get the similar figures after dilation but they are not congruent.)
Therefore, we can not consider dilation an isometry.
Answer:
60 degrees
Step-by-step explanation:
A triangle is 180 degrees and there is already 40 and 80 degrees.
So... 180-80-40=60 degrees.
Hope this helps :D
Easy:
formula for parallelogram is b times h
so 5 times 14 =
70 sq mm.
Answer:
10.50x ≤ 205
The maximum number of tickets, x, would be 19.
Step-by-step explanation:
Given,
The cost of one ticket = $ 10.50,
The cost of x tickets = 10.50x dollars,
Since, the total cost can not exceed $ 205,
⇒ 10.50x ≤ 205
∵ 10.50 > 0 thus, when we multiply both sides by 1/10.50 the inequality sign will not change,
⇒ x ≤ 
≈ 19.52
Hence, the maximum number of tickets would be 19.
Answer:
19 cars
13 buses
Step-by-step explanation:
We have a system of equations as follows
X + y = 32 -----1
3x + 27y = 408 ----2
x = car
y = bus
From equation 1
x + y = 32
x = 32 - y ---- 3
We put equation 3 into equation 2
3(32-y) + 27y = 408
96y -3y + 27y = 408
96 + 24y = 408
24y = 408 - 96
24y = 312
Divide through by 24 to get the value of y
Y = 312/24
Y = 13
We put the value of y in equation 3
x = 32 - 13
x = 19
So 19 cars would be needed for the trip and also 13 buses would also be needed
