Sally and dana take a walk in the park for every 5 strides that sally make dana makes 4 strides after sally makes 120 strides ho
olga_2 [115]

Dana made 96 strides.

Step-by-step explanation:

Given,

Ratio of Sally's stride to Dana's strides = 5:4

Strides made by Sally = 120

Let,

x be the strides made by Dana.

Ratio of Sally to Dana = 120:x

Using proportion;

Ratio of Sally's stride to Dana's stride :: Ratio of Sally to Dana

5:4::120:x

Product of mean = Product of extreme

4*120=5*x\\480=5x\\5x=480

Dividing both sides by 5

\frac{5x}{5}=\frac{480}{5}\\x=96

Dana made 96 strides.

Which choice answer is it?
nekit [7.7K]

Answer:

2. a1 = 10 and an = a(n-1) + 2

Step-by-step explanation:

10 is our first term so it would be a of 1.

Then, in this arithmetic sequence, it is increasing by 2.

So, therefore our recursive formula for this arithmetic sequence would be:

a(n) = a(n-1) + 2
