Answer:

The Correct Answer would be 5, Why? lets get into it.

Step-by-step explanation:

what we know is that Lauren bought soup for $40.

25% off 40 would be 10, 10-40=30 so Lauren´s soup now cost´s $30.

Now Lauren is at check out and tax is 10% of Lauren´s soup which is 10-30.

so 10% of 30 is 3 so Lauren´s soup originally costed $40 but +sale´s +tax now costs $33.

Insert geometric means in each geometric sequence.

Digiron [165]

Answer:

$\underline{192}, 24, \underline{3}, \underline{\dfrac{3}{8}}, \dfrac{3}{64}$

$\underline{\dfrac{1}8}, \dfrac{1}{4}, \dfrac{1}{2}, \underline{1}$

$81, \underline{27, 9, 3, 1},\dfrac{1}{3}$

Step-by-step explanation:

Given the Geometric sequences:

1. ___, 24, ___, ___, 3/64

2. ___, 1/4, 1/2, ___

3. 81, ___, ___, ___, ___, 1/3

To find:

The values in the blanks of the given geometric sequences.

Solution:

First of all, let us learn about the $n^{th}$ term of a geometric sequence.

$a_n=ar^{n-1}$

Where $a$ is the first term and

$r$ is the common ratio by which each term varies from the previous term.

Considering the first sequence, we are given the second and fifth terms of the sequences.

Applying the above formula:

$ar = 24\\ar^4 = \dfrac{3}{64}$

Solving the above equation:

$r = \dfrac{1}{8}$

Therefore, the sequence is:

$\underline{192}, 24, \underline{3}, \underline{\dfrac{3}{8}}, \dfrac{3}{64}$

Considering the second given sequence:

$ar = \dfrac{1}{4}\\ar^2 = \dfrac{1}{2}\\\text{Solving the above equations}, r = 2$

Therefore, the sequence is:

$\underline{\dfrac{1}8}, \dfrac{1}{4}, \dfrac{1}{2}, \underline{1}$

Considering the third sequence:

$a = 81\\ar^5=\dfrac{1}{3}\\\Rightarrow r = 3$

Therefore, the sequence is:

$81, \underline{27, 9, 3, 1},\dfrac{1}{3}$

Combine like terms to create an equivalent expression 2s+ (-4s) pls help

pav-90 [236]

The equivalent expression to $2s + (-4s)$ is $-2s.$

Step-by-step explanation:

Step 1:

In sums like these, it is easier to take the common term out of the simplification.

In the expression $2s + (-4s)$ , the common term between $2s$ and $-4s$ is the term s. So we take the term s as the common factor.

So taking s out of $2s + (-4s)$ we get $s (2+(-4)).$

Step 2:

If we multiply a positive with a negative we get a negative. S0 $+(-4) = -4.$

$2s + (-4s) = s (2-4) = s(-2) = -2s.$

So the equivalent expression to $2s + (-4s)$ is $-2s.$

Natasha and her two dogs were walking on a perfectly straight road when her two dogs ran away from her in opposite directions.

EastWind [94]

Answer:

$\dfrac{74}{20}=3.7 meters$

Step-by-step explanation:

Hello!

1) Since no other data has been given. Suppose Natasha is in the center and the beagle is to the right.

$\dfrac{25}{4} \:meters$

2) The labrador is $\dfrac{51}{20}\: to\: the\: left.$

$\dfrac{25}{4} -\dfrac{51}{20} =\dfrac{(5*25)-51}{20} \\\dfrac{(125-51}{20} =\dfrac{74}{20}$
