My bad i used S instead of A so just switch the letter. hope this helps tho have a nice day
Answer:
C/d = 31.4/10
Step-by-step explanation:
We know the formula of the circumference, which ir:
C = pi*d
Where C is the circumference and d is the diameter of the circle. If we want to know the value of the pi number we just need to divide both sides of the equation above by d:
C/d = pi*d/d
C/d = pi
Thus, we can write pi as the ratio C:d or C/d, which means, how many times the diameter enters on the circumference. In our case is:
pi = 31.4/10 = 3.14
And 3.14 is how we usually use the pi number.
Answer:
A
Step-by-step explanation:
It's not B, since that is describing a <em>line graph</em>.
It's not C, since that is describing a <em>table</em>.
Out of <em>A and D, they both work</em>, but A sounds more fitting.
Using proportions, considering the amount she received from each person, it is found that Annie had 30 sweets originally.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three.
In this problem, we have that:
- Initially, she had n sweets.
- With the ones she got from Teddy, the amount became 1.5n.
- With the amount from Rosie, the amount became 1.4 x 1.5 x n.
The final amount was of 63, hence:
1.4 x 1.5 x n = 63
n = 63/(1.4 x 1.5)
n = 30.
Annie had 30 sweets originally.
