A. –1.73205081…
B. 1/4
C. 0.54732871…
D. √3

Answers

Answer 1

Answer:

Option B is correct 1/4.

Step-by-step explanation:

To find : Which number produces a rational number when added to 0.5?

Solution :

A rational number is defined as number written in simple fraction or in p/q form.

An irrational number is defined as number which cannot be written in p/q form.

We know that,

A rational number adding a rational number gives you a rational number.

A rational number adding an irrational number gives you a irrational number.

Now we take each option and check.

Option A : -1.73205081…

Number has no end and have infinite number of digits so it is irrational number.

No, this number not produce a rational number.

Option B : 1/4=0.25

Number is in form p/q so it is rational number.

Yes, this number produce a rational number.

0.25+0.5=0.75 a rational number.

Option C : 0.54732871…

Number has no end and have infinite number of digits so it is irrational number.

No, this number not produce a rational number.

Option D : \sqrt{3}

\sqrt{3} cannot be written in ratio so it is irrational number.

No, this number not produce a rational number.

solve for x if z = m - x

Answers

Answer:

x=m-z

Step-by-step explanation:

The first step is to isolate x and to do this we got to subtract m from both sides which would give us -m+z=-x, the next step is to get x to be positive so we have to divide both sides by negative 1 which is because there is a 1 beside all of the values, and when we do divide both sides by negative 1 we get x=m-z

y = 3x - 2
x - y = 4

Answers

Answer:

x=-1, y=-5

Step-by-step explanation:

y=3x-2 (1)

x-y=4 (2)

sub (1) into (2)

x-(3x-2)=4

x-3x+2=4

-2x=2

x=-1

sub x=-1 into (1)

y=3(-1)-2

 =-3-2

y = -5

Therefore: x=-1, y=-5 :))

Answer:

x = -1, y = -5

Step-by-step explanation:

y = 3x - 2

x - y = 4

x - y = 4

x - (3x - 2) = 4

x - 3x + 2 = 4

-2x + 2 = 4

-2x = 2

x = -1

x - y = 4

-1 - y = 4

-y = 5

y = -5

Check:

x - y = 4

-1 - (-5) = 4

-1 + 5 = 4

4 = 4

help pls and i need the steps :/​

Answers

Answer:

4

Step-by-step explanation:

Lets make [tex]x[/tex] be the ? in the equation.

That becomes ([tex]x[/tex] x 3) - 3 = 15.

First you have to add 3 on both sides. After doing that it gets to ([tex]x[/tex] x 3) = 15 - 3.

Then you simplify it to 3[tex]x[/tex] = 12.

Now you divide 3 on both sides. That gets to [tex]x[/tex] = 4 after doing it.

Please help this fairly quick

Answers

Answer:

A) true

B) false

c) true

d) true

Step-by-step explanation:

A) angles 7 and 6 are vertical angles, which means they're equal.

so, A is True.

B) angles 7 and 5 are supplementary angles, which means they add up to 180. 135 + 55 is 190. so B is False

C) angle 7 is equal to angle 3, which is supplementary to angle 1.

so, 55 + angle 1 = 180

55 + angle1 = 180

subtract 55 from both sides of the equation

angle1 = 180 - 55

angle 1 = 125.

angles a and 4 are vertical angles, so they are equal. if you add them together that would be 125 + 125

125 + 125 = 250

so, C is True

D) angles 1 and 6 are supplementary, and angles 2 and 7. since they both add together to make 180, D is True

Let's work it out slowly

A)

$18.79 + $2.11 - $1.92 + $17.28

- 18.79 + 2.11 + 17.28 = 38.18

- 38.18 - 1.92 = 36.26

Ans = $36.26

B)

$7.45 + $24.45 + $74.17 + $76.52

Ans = $182.59

C) $98.45 - $10.63 + $2.82 - $20.26

Jack plans to buy 2.25 lb of coleslaw at $2.80 per pound. He also wants 2lb of macaroni salad that sells for $3.15 per pound. Jack has a $10 bill in his wallet. Is this enough for the coleslaw and the macaroni? Explain.

Answers

No

2.25 times 2.80 gives the cost for the total coleslaw, which is $6.30
2 times 3.15 gives the cost for the total macaroni salad, which is also $6.30
Add those together and you get $12.60, which is larger than $10, so it is not enough
First, multiply 2.25 by 2.80 to get the cost of the coleslaw, which happens to be $6.30. Then, multiply 3.15 times 2, which would also get $6.30. Last, add $6.30 + $6.30, to get $12.60, which is more than $10, so he doesn’t have enough.

Use the diagram and the given angle measure to find the other three measures.

m∠1=143∘

m∠2=

m∠3=

m∠4=

Answers

Answer:

angle 2 = 37⁰

angle 3 = 153⁰

angle 4 = 37⁰

Step-by-step explanation:

I guess this refers to two intersecting lines which form 4 angles.

Angles 1 and 2 are supplementary angles whose sum is 180⁰.

Angle 1 + angle 2 = 180⁰

143⁰ + angle 2 = 180⁰

angle 2 = 180⁰ - 143⁰

angle 2 = 37⁰

Angles 1 and 3 are vertical angles so do with angles 2 and 4. Therefore it is easy to find their measures because vertical angles are congruent in measures.

Hope this helps...

Answer:

m∠1 = 143°

m∠2 = 37°

m∠3 = 143°

m∠4 = 37°
