Nadusha1986 [10]

Answer:

<h2>10 weeks </h2>

Step-by-step explanation:

Step one:

given data

Ryan

number of baseball cards=150

number collected per week= 10

let the number of weeks be x

and the total be y

y=10x+150-----------------1

Sarah

number of baseball cards=200

number collected per week= 5

let the number of weeks be x

and the total be y

y=5x+200------------2

Step two:

Required

the number of weeks where both total will be the same

10x+150=5x+200

10x-5x=200-150

5x=50

divide both sides by 5

x=50/5

x=10 weeks

Choose the correct expressions using the fewest number of bases possible that are equivalent to the current expression. Select A

rjkz [21]

<h3>2 Answers: Choice B, Choice C</h3>

The rule we use here is $\frac{a^b}{a^c} = a^{b-c}$

If the font size is too small, then it says (a^b)/(a^c) = a^(b-c)

We subtract the exponents when dividing exponentials like this. The bases must be the same.

So this means the exponents 13 and 3 subtract to get 13-3 = 10

We either have an exponent of "13-3" or an exponent of "10" as an equivalent expression. The base stays at 2 the entire time.

Brenda completes her sixth hiking trail in a state park. A park ranger tells her that she has hiked 25% of the trails. How many

Maurinko [17]

Answer:

Total number of hikes in the state park = 24

Step-by-step explanation:

Let the number of trails available in the state park = t

Since, Brenda has completed 25% of the total trails, number of trails completed by her = 25% of t

= $\frac{25}{100}\times t$

= 0.25t

As per ranger she has completed 6th hiking trail,

6 = 0.25t

t = $\frac{6}{0.25}$

t = 24

Therefore, total number trails to hike in the state park = 24.
