Which Of The Following Expressions Are Equivalent To -\dfrac{2}{-13} 132 Minus, Start Fraction, 2, Divided

Answers

Answer 1

Answer:

Step-by-step explanation:

We are given:

     

      2

- ----------

    -13

Since a negative number (-2) divided by another negative number results in a positive number,

      2

  ----------

     13

Both Answers A and B are correct; the final value in each case is +2/13.

Answer 2

The equivalent expression will be (-2)/(-13) and-(-2/13) so option (A) and option (B) both will be correct.

What is numerator and  denominator?

In such a fraction, the value that appears above the horizontal line is referred to as the numerator. It represents the number of pieces removed from the whole.

The denominator of a fraction is the numerical value that comes before the brings together various.

If we divide two numbers by each other then the upper word is called the numerator, and a lower word is called the denominator. For example a fraction 1/5 here 1 will be the numerator and 5 will be denominated.

Given that[tex]-\dfrac{2}{-13}[/tex]  now since the multiplication of - and - quantity is always positive so - and - is positive so it will be 2/13

If you take both options A  and B in both options the negative sign going to cancel and it will give a positive value.

Hence "The equivalent expression will be (-2)/(-13) and-(-2/13)".

In the figure shown, line AB is parallel to line CD.

Part A: What is the measure of angle x? Show your work. (5 points)

Part B: Explain how you found the measure of angle x by identifying the angle relationships that you used along the transversal. (5 points)

Answers

Answer:

Part A

x is 46°

Part B

Alternate angles are angles that are in relatively opposite locations relative to a transversal

Step-by-step explanation:

Part A

∠DRP  = 110° (Given)

∠QPA = 64° (Given)

∠QPR =

Given that AB is parallel to CD, we have;

∠DRP is congruent to ∠APR (Alternate angles to a transversal RP of parallel lines AB and CD)

Therefore, ∠APR = 115°

∠APR = ∠QPA + ∠QPR (Angle addition postulate)

∴ 115° = 64° +  ∠QPR

∠QPR = 110° - 64° = 46°

x = 46°

Part B.

Given that AB is parallel to CD, the lines common (that intersects) both lines are the transversal lines

The angles formed between the parallel lines and the transversal lines have special relationships based on their position with respect to each other

In the question, the angle 110° given between CD and the transversal RP, is found to at an alternate position to the angle ∠APR between the same transversal RP and AB and given that alternate angles are always equal, angle ∠APR is therefore also equal to 110°.

X would equal 46 degrees

Answers

Answer:

your answer is C. -2/3

Step-by-step explanation:

In mathematics, the additive inverse of a number a is the number that, when added to a, yields zero. This number is also known as the opposite (number), sign change, and negation. For a real number, it reverses its sign: the additive inverse (opposite number) of a positive number is negative, and the additive inverse of a negative number is positive. Zero is the additive inverse of itself. In this case, -2/3 is the additive inverse of 2/3.

2 (l + b) × h ---> For Lateral surface area

2(30+30) h = 7200

2×60×h = 7200

120 × h = 7200

h = 7200/120

h = 60 cm

Now, volume = l×b×h

= 30×30×60

= 54000 cm³ is the required answer.

small pot holds 36 units

let x be quantity of water in large pot

According to the question,

75% of x = 36 units

75/100 * x= 36

75x/100= 36

75x= 36*100

75x= 3600

x= 3600/75

The measures of two angles in a triangle are 32o and 78o. Which of the following equations could be used to find the measure of the third angle, x?
(the ¨o¨ is a degree symbol)


180−32+78=x


180−32=x−78


180−(32+782÷2)=x


32+78+x=180

Answers

Answer:

32+78+x=180

Step-by-step explanation:

All triangle angles add up to 180, so add 78 and 32 then subtract it from 180 to get x, which in another form is 32+78+x=180.

Answer:

32 + 78 + x = 180

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

Sum the 3 given angles and equate to 180, that is

32 + 78 + x = 180

A) what is the simplified product of seven-fourths divided by eight-fifths as an improper fraction

B) what is this number as a mixed number

Answers

Answer:

A) 

First were going to put our numbers in perspective.

[tex]\frac{7}{4}[/tex] ÷ [tex]\frac{8}{5}[/tex]

But to find the improper fraction, we have to cross multiply these numbers.

[tex]\frac{7}{4}[/tex] × [tex]\frac{8}{5}[/tex]

7 x 5 = 35.  

4 x 8 = 32.

Now we have our improper fraction is  [tex]\frac{35}{32}[/tex]

B)  

To turn our improper fraction into a mixed number, we will use division.

We know that the 32 can only go into 35 one time.  We also know that the bottom number always stays the same.  So our equation will look somewhat like this.

[tex]1\frac{?}{32}[/tex]

Now to fine the top number we will have to subtract 35 from 32 because we already know that 32 can go into 35 one time, so 35 - 32 = 3.  So are mixed number will look like this.

[tex]1\frac{3}{32}[/tex]

This is our answer!

Answer:

7/4 ÷ 8/5

A. First, we need to do the reciprocal of 8/5.

7/4 x 5/8 = 35/32

B. Now, we need to convert it into a mixed number. Divide 35 by 32. 32 goes into 35 one time. 35 - 32 = 3, so remainder 3. We use 1 as the whole number since 32 goes into 35 one time. We use the remainder 3 as the numerator, and 32 as the denominator.
