Answer: 5.026548. or 5.03
Step-by-step explanation:
circumference is pi times diameter
1.6 x pi is 5.026548, which simplified is 5.03
Answer:
let 3:2 be 3x& 2x
perimeter =40
2(l+b)=40
2(3x+2x)=40
5x=40/2
x=20/5=4cm
length=3x=3×x=3×4=12cm
breadth =2x=2×4=8cm
area of rectangle =l×b=12×8=96cm²
Answer:
Step-by-step explanation:
The most important part of this question is the estimation. That means you round either up or down to get whole numbers.
You can make - 37.44 either - 40 or - 35
You can make 4.8 into 5
So the answer should lie between -40/5 = - 8
or
The answer should be between - 35/5 = - 7
Use your calculator to check it.
-37.44 ÷ 4.8 = - 7.8
This skill is very handy when shopping or writing a test. It you get an outrageous answer like - 21.44 you know you have done something wrong.
Answer:
C. Alternate interior angles are congruent
Step-by-step explanation:
<Y and <4 are two alternate angles within the two parallel lines cut across by the transversal, hence, they are called alternate interior angles.
Alternate interior angles are always congruent to each other. Therefore, the reason that justifies statement two: "<Y ≅ <4", is "Alternate interior angles are congruent".
