The number of number of house holds have pets will be 21450 when 20,735 households do not have pets.
What is proportion ?
A proportion is an equation based on the equality of two ratios.
It is given that the ratio of the households with pets to house holds without pets is 30 to 29 and if 20,735 households do not have pets then it is find the number of number of house holds have pets. It can be find out using the ratio correlation :
That is , 29 is the ratio of house holds without pets ⇒ 20735
1 unit of house holds without pet ⇒ 20735/29 = 715 house hold
Now, the ratio of households with pets ⇒ 30 x 715 = 21450 house hold
Therefore, the number of number of house holds have pets will be 21450 when 20,735 households do not have pets.

Answer:
18. 28 cm*2
19. 24 m
Step-by-step explanation:
18. length × l = 16
l*2= 16
l = 4
RQ = 4 cm
PR =7cm
Area of parallelogram = b×h
= 7×4
=28cm*2
19. 8 +8 + (6-2) +( 6- 2)
=24 m
Answer:
D
Step-by-step explanation:
(-7x^2 - 3) + (4x - 6)
-3 - 6 = -9
-7x^2 + 4x - 9
The diagram shows the coordinates of the vector. They are:
East-coordinate = 6
North-coordintate = 4
A) To find the magnitude you just use Pythagorean theorem:
c^2 = 6^2 + 4^2 = 36 + 16 = 52 => c = √52 = 7.21
7.21 rounded to the nearest tenth is 7.2
B) To find the direction find the angle using trigonometric ratios:
tan(angle) = 4/6 = 2/3 => angle = arctan(2/3) = 33.69 degrees
That is 33.69 degrees North of East, which is written N 33.69° E
A is the answer hope it helps you
