The anwser is ten because the number i saw is 14 estimate is ten.
Answer:
15
Step-by-step explanation:
70÷14=5
5×3=15
So the ratio would be 70:15 which can be simplified to 14:3
Let S = spoon
Let K = knife
1 knife is thee times the cost of a spoon, so it would be 3S
Now you have 9S + 12K = 82.80
We can replace the K with 3S:
9S +12(3S) = 82.80
Simplify the left side:
9S + 36S = 82.80
Add:
45S = 82.80
Divide both sides by 45"
S = 82.80 / 45
S = 1.84
One spoon cost $1.84
We know one knife cost 3 times as much, so multiply the cost of a spoon by 3:
Knife = 1.84 x 3 = $5.52

Answer:
Circumference, C = 81.68 units
Step-by-step explanation:
Given that,
The radius of the circle, r = 13 units
We need to find the circumference of the circle. The circumference of a circle is the sum of the outer boundary. For a circle, it is given by :
C = 81.68 units
So, the circumference of the circle is 81.68 units. Hence, this is the required solution.
