Answer:
10.2cm
Step-by-step explanation:
Perimeter is the sum of the lengths of all sides.
1st side: 9cm
2nd side: 7.8cm
Perimeter: 27cm
Perimeter = 1st + 2nd +3rd side of a triangle
27cm = 9cm +7.8cm + 3rd side
3rd side = 27cm - 9cm -7.8cm
= 10.2cm
69.1 is already a decimal.
Answer: Treats are an essential part of positive reinforcement, rewards-based training, but you also need to be mindful to balance your dog’s treats with their overall daily calories. Give them too many treats and you won’t just spoil their appetite for actual meals, but you could also make your dog overweight and unhealthy.

Answer:
$2.40
Step-by-step explanation:
First, you would do 22.70 minus 3.50, to get 19.20.
Then, you would divide 19.20 by 8, to get 2.4.
So, if each pineapple was the same price, each pineapple would be $2.40.
Answer:
boys = 250
girls = 150
Step-by-step explanation:
5g = 3b eq. 1
g + b = 400 eq. 2
g = girls
b = boys
From the eq. 2
g = 400 - b
Replacing this last eq. on eq. 1:
5(400-b) = 3b
5*400 + 5*-b = 3b
2000 - 5b = 3b
2000 = 3b + 5b
2000 = 8b
2000/8 = b
250 = b
From eq. 2
g + 250 = 400
g = 400 - 250
g = 150
Check:
from eq. 1
5*150 = 3*250 = 750
