Answers
Answer:
48 metres.
Step-by-step explanation:
How far does the cyclist travel in 3 seconds:
First, find how far the cyclist goes in 1 second:
320 metres = 20 seconds
? = 1 second
320 ÷ 20 = 16 metres
The cyclist travels 16 metres in 1 second.
How far does the cyclist travel in 3 seconds:
1 second = 16 metres
3 seconds = ?
16 × 3 = 48 metres.
The cyclist travels 48 metres in 3 seconds.

Answers
Answer:
Solution: 17 > 1
Step-by-step explanation:
First of all, let's make a review of Greater and Lower Than symbols
a < b means that a is lower than b.
a > b means that a is grater than b.
Notice that vertex of < sign always points to the smallest number.
Using our own words, the expression 17 > ? means that 17 is greater than an unknown number ?.
We are going to test each of the options to find the one that satisfies that 17 is greater than the tested number.
17 > 39 means that 17 is greater than 39. This is False since 39 is greater than 17.
17 > 17 means that 17 is greater than 17. This is False since 17 equal to 17.
17 > 1 means that 17 is greater than 1. This is True since 17 is greater than 1.
17 > 18 means that 17 is greater than 18. This is False since 18 is greater than 17.

We have then:
k = 6/4 = 3/2
Then, the area will be given by:
A '= k ^ 2 * A
Substituting values:
A '= ((3/2) ^ 2) * (20)
A '= 45 cm ^ 2
Answer:
The area of PQR is:
A '= 45 cm ^ 2
Answer:
Area of ΔPQR = 45 cm²
Step-by-step explanation:
From the given figure we can see that triangle ABC and triangle PQR are similar triangles.
If two triangles are similar the the ratio of area of two triangle is equal to the square of ratio of corresponding sides
To find the area of triangle PQR
Ar(ABC) = 20, AB = 4 cm and PQ =6 cm
From figure we can write,
Ar(ABC)/ar(PQR) = (AB/PQ)²
20/ar(PQR) = (4/6)²
20/ar(PQR) = 16/36
ar(PQR) = (36 x 20)/16 = 45 cm²
