Answer:

<h2>You answer is ⅞.</h2>

Step-by-step explanation:

\frac{3}{4}  +  \frac{1}{8}

To solve this question we need to make the denominators same.

We can make it by finding the L.C.M.

We know,

The L.C.M of 4 and 8 is 8.

So therefore the fractions will become -

\frac{3}{4}  =  \frac{3 \times 2}{4 \times 2}  =  \frac{6}{8}

And

\frac{1}{8}  =  \frac{1 \times 1}{8 \times 1}  =  \frac{1}{8}

Now we can add the numbers

\frac{6}{8}  +  \frac{1}{8}  =  \frac{6 + 1}{8}  =  \frac{7}{8}

So the answer is ⅞.

Hope it helps you!!

Anna [14]

Using the information given in the question, the total number of liters Margie will drink in a 4 week period is 39

<u>Consider the given information:</u>

<u />

  • 12.25 liters per week
  • Continues this for 4 weeks

<u>Equation formed with said information:</u>

Liters per week  ×  The 4-week period

<u>Solving the equation</u>

12.25 × 4

= 49

Therefore, after the 4-week period Margie would of drank 49 liters

Answers:

  • A) Ray QS or Ray QR
  • B)  Line segment QS or SQ
  • C)  Plane QSR
  • D)  Line QS or RQ

=======================================================

Explanation:

Part A)

When naming a ray, always start at the endpoint. This is the first letter and we'll start with point Q.

The second letter is the point that is on the ray where the ray aims at. We have two choices S and R as they are both on the same ray. That's why we can name this Ray QS and Ray QR.

--------------------

Part B)

A segment is named by its endpoints. The order of the endpoints doesn't matter so that's why segment QS is the same as segment SQ. To me, it seems more natural to read from left to right, so QS seems better fitting (again the order doesn't matter).

--------------------

Part C)

When forming a plane, you need 3 noncollinear points. The term "collinear" means the points all fall on the same line. So these three points cannot all fall on the same straight line. In other words, we must be able to form a triangle of some sort.

So that's how we get the name "Plane QSR". The order of the letters doesn't matter.

--------------------

Part D)

To name a line, we just need to pick two points from it. Any two will do. The order doesn't matter. So that's how we get Line QS and Line RQ as two aliases for this same line. It turns out that there are 6 different ways to name this line.

  1. Line QR
  2. Line QS
  3. Line RQ
  4. Line RS
  5. Line SQ
  6. Line SR

2sin^2x - sinx - 3 = 0
e-lub [12.9K]
We have that
2sin²<span>x - sinx - 3 = 0
</span>
Let
A------> sin x
so
2A²-A-3=0

using a graph tool-----> to resolve the second order equation
see the attached figure

the solutions are
A=-1
A=1.5------> is not solution because sin x <span>can not be 1.5

the solution is
A=-1
therefore
sin x=-1
x=arc sin(-1)=-90</span>°

the answer is
sin x=-1
x=-90° or 270°
