Answer: perimeter: 40.79
Area: 84
Step-by-step explanation:
perimeter: (√3² + 6²) + (√1² + 6²) + 7 + 6 + 6 + 9 = 40.79
area: ((9 + 6) x 6) / 2 + ((6 + 7) x 6) / 2) = 45 + 39 = 84
Here you must do mult. and div. BEFORE add'n. and subtr'n.
<span>23 + 5 × 10 ÷ 2 – 33 + (11 – 8)
Mult 5*10, and then div. the result by 2. Then you will have
23 + 25 - 33 + 3
This simplifies to: 51-33 = 18</span>
Fifty-six biscuits are to be fed to 10 pets; each pet is either a cat or a dog. each dog is to get six biscuits, and each cat is to get five. how many dogs are there?
Answer: There are 6 dogs
Explanation:
Total number of biscuits = 56
Total number of Pets = 10
Now each dog is to be given 6 biscuits and each cat is to be given 5 biscuits.
Now if there are 6 dogs and each is to be given 6 biscuits and total biscuits given to 6 dogs = 6 x 6 =36
and there are 4 cats and each is to be given 5 biscuits and total biscuits given to 4 dogs = 4 x 5 =20
Therefore, total biscuits given to 6 dogs and 4 cats is 36+20= 56
