Divide 5 by 3.
If you do this on a calculator you will get 1.666666667.
You will then round that to 1.7
Because "4 or less let it rest, 5 or more raise the score"
A=base*height*1/2 OR A=base*height/2
A=8*7/2
A=28
Answer:
Rectangle B is a scaled copy of rectangle A.
Enlargement scale factor = 1.25
Step-by-step explanation:
<u>Rectangle A:</u>
Length = 12 units
Width = 8 units
<u>Rectangle B:</u>
Length = 15 units
Width = 10 units
<u>Rectangle C:</u>
Length = 30 units
Width = 15 units
Rectangle B length ÷ rectangle A length = rectangle B width ÷ rectangle A width = 1.25
i.e 
= 
= 1.25
Hence rectangle B is a scaled copy of rectangle A and the scale factor of enlargement is 1.25
Answer:
LM = 6 cm
Step-by-step explanation:
A square has all the sides equal in length. The opposite sides of a square is parallel to each other and all the angles are equal to 90°.
Therefore , the square QRST has all it sides equal in length. Likewise the square KLMN .
The ratio of side QR to the length side KL is 3:2 . If the side ST = 9 cm , The length of side LM can be gotten below.
ST = 9 cm since QRST is a square all the other sides are 9 cm . The length of KLMN is equal for all sides too. The ratio for any sides of square QRST to any sides of square KLMN is the same through out.
Therefore,
3/2 = 9/LM
cross multiply
3LM = 18
divide both sides by 3
LM = 18/3
LM = 6 cm
