Write a unit rate for the situation
250 words in 5 minutes

Answers

Answer 1
Answer: To write a unit rate we have to find out, something per something. Here we will find out how many words per min. TO do this we will divide the amount of words (250) by the amount of minutes (5). Lets do it:-

250 ÷ 5 = 50
50 words per min.

CHECK OUR WORK:-

50 × 5 = 250
We were RIGHT!!

So, a unit rate for the situation "250 words in 5 minutes" is 50 words per min.

Hope I helped ya!! xD
Answer 2
Answer: 250 words in 5 minutes
To find how many words per minute, divide 250 by 5.
That would give you 50 words per minute. 
This would be a linear equation because there is a steady unit rate.
The rate is 5 so the equation is
y=5x
Hope this helps.

2/3 + 3/4 

First, we need to find a common denominator.

2*4/3*4 = 8/12

3*3/4*3 = 9/12

Now add the numerators.

9+8 = 17

17/12 = 1 5/12

Answer: 1  5/12

5 * 3/4 = 

5/1 * 3/4 = 15/4

15/4 = 3  3/4

Answer: 3  3/4
2/3 + 3/4
For this, you want to cross multiply
To do this, you do the first numerator (2) multiplied by the second denominator (4), and the first denominator (3) multiplied by the second numerator (3).If you draw lines between the two numbers you are multiplying, a 'cross' is made. Add these two numbers together to make the new numerator. For the denominator, multiply the bottom two numbers.
Next simplify the new fraction (Follow attached  image)

5 x 3/4
This can be written as 5 x 3 / 4
5 x 3 = 15
15/4 = 3 3/4 or 3.75

1,000 more than 37,568 isa.36,568 b.37,468
c.37,668 d.30,000

Answers

i would have to say none of them are correct :(
1000 more than 37568 would be 38568
it is a.36,568 because if u subtract 37,568 from 1,000 that gets u the answer

Any help is welcome :) only right answers get brainilest

Explicit rule formula: a(n) = a · rⁿ⁻¹

a(n) = ⁿth term

a = first term

r = common ratio

ⁿ⁻¹ = the previous term

In the recursive rule a₁ = 2/3; aₙ = 9 · aₙ₋₁ the first term is 2/3 and the common ration is 9. We can fill in the explicit formula with what we know.

Thus, the correct answer is [ aₙ = 2/3 · 9ⁿ⁻¹ ]

Best of Luck!

Answer:

a_(n) =(2)/(3)*9^(n-1)

Step-by-step explanation:

a1 = 2/3

an = 9*a(n-1)

a2 = 9 *a1 = 9* 2/3

a3 =9*a2 = 9 *(9*2/3) = 9²*2/3

a4 = 9*a3 = 9* (9²*2/3) = 9³*2/3
