Answer:
5 pieces of 40 cm
Step-by-step explanation:
A Bar of steel is 340 cm long Issa cuts two 55cm lengths of the bar
He then cuts the rest into as many 40cm lengths as possible
Work out how many 40cm lengths of bar Issa cut.
so
340cm - 55 cm - 55 cm = 230 cm remains
<u>230 cm </u>to cut into 40 cm as many as possible
40 cm
therefore, there are 5 pieces of 40 cm
Remember:
a) (x,y) => (x, -y) is a reflection across X axis
b) (x,y) => (-x,y) is a reflection across Y axis
Here △RST is mapped to △R′S′T′ using the rule (x,y)→(x,−y)
Hence it is a reflection across X axis.
The size of the triangle does not alter.
But when this is followed by (x,y)→(3x,3y), the lengths increase by a factor 3.
Hence the triangles do not remain congruent.
△RST is not congruent to △R′S′T′ because the rules do not represent a sequence of rigid motions.
Option A) is the right answer
Answer:
2
Step-by-step explanation:
60 min = 1 hour
120 min = 2 hours
since you cant go into 135 more than twice it be two hours
