Answer: 30 minutes

Step-by-step explanation:

1/10 miles = 1 minute

3 miles = x

1/10x = 3

Multiply both sides by 10

x = 30

Isa would run 3 miles in 30 minutes.

Find the two geometric means between 20 and 2500

iris [78.8K]

Answer:

<h2>The two geometric means between 20 and 2500 are 100 and 500.</h2>

Step-by-step explanation:

First of all we all should know about a geometric progression to solve this question.

A geometric progression is a series in which there is a first term a and all the next terms are calculated by multiplying the previous term by a common number r.

where a is known as first term and

r is known as common ratio.

In the question we are given a as 20 and we have to find out 2 terms after 20 and 4th term is given as 2500.

Formula for $n^{th}$ term in a geometric progression is:

$a_{n} = a\times r^{n-1}$

Here $a_{4}$ = 2500

As per formula of $n^{th}$ term:

$a\times r^{3} = 2500\\\Rightarrow 20 \times r^{3} =2500\\\Rightarrow r^{3} = 125\\\Rightarrow r = 5$

Now, 2nd term:

$a_{2} = a \times r\\\Rightarrow a_{2} = 20 \times 5\\\Rightarrow a_{2} = 100$

Now, 3rd term:

$a_{3} = a \times r^{2} \\\Rightarrow a_{3} = 20 \times 5^{2}\\\Rightarrow a_{3} = 500$

So, the two geometric means between 20 and 2500 are 100 and 500.

GiveN:

ABCD is a parallelogram.
AC and BD are the diagonals.
DE = 28 units

To FinD:

Value of x in length of BE?

Step-wise-Step Explanation:

We know that $,$

In any parallelogram, the diagonals (lines linking opposite corners) bisect each other. Then, AE = EC for diagonal AC and BE = DE for diagonal BD.

⇒ BE = DE

⇒ x - 4 = 28 units

⇒ x = 32 units

Hence, The required value of x here is 32 units.

Suzie just became a personal trainer and is finalizing her pricing plans. One plan is to charge $59 for the initial consultation

soldier1979 [14.2K]

Answer:

2 sessions, $231

Step-by-step explanation:

Make an equation (let x represent the number of sessions)

59+86x=63+84x

Subtract 84x from both sides

59+2x=63

Subtract 59 from both sides

2x=4

Divide by 2

x=2

At 2 sessions they will be equal

To find the cost, substitute 2 in for x

59+86(2)=63+84(2)

59+172=63+168

231=231

So, at 2 sessions the plans will cost the same at $231

Hope this helps! :)

never [62]

the change in the scale factor is $\frac{45}{40}$ .Correct option C) StartFraction 45 feet over 40 feet EndFraction

Step-by-step explanation:

Here we have , Norma Ann planned a rectangular courtyard, as shown in the scale drawing below. A rectangle with length of 15 inches and width of 5 inches. She decides to change the width, the shorter side of the courtyard, from 45 ft to 40 ft. We need to find Which expression finds the change in the scale factor . Let's find out:

Initially the ratio of width to actual width is :

⇒ $\frac{5}{45}$
