Answer:

C and D.

Step-by-step explanation:

I am guessing that he wants to find if 2 is a rational number by comparing it to  the fraction [tex]\frac{\sqrt {2}}{1}[/tex]

There are a couple of reasons why Mark is not correct:

1. A number is rational only if it can be written as a fraction made up of the numerator and denominator as integers.

2. The fraction [tex]\frac{\sqrt {2}}{1}[/tex] is not equal to 2, so, he is wrong.

So, C and D would be correct.

NOTE: In case I misinterpreted the question, use 1. to judge if it is rational or not, you should get your answer.

Answer:

Mark is not correct because a fraction is rational only if the numerator and the denominator are both integers.​

Answer:

Step-by-step explanation:

The triangle CBV is angled triangle with right angle at ∠VBC.

Since  ∠VBC = (3x-4) °

To get the value of x, we will equate the angle  ∠VBC to 90°

This results into (3x-4) ° = 90

Simplifying the resulting equation;

3x-4 = 90

Adding 4 to both sides;

3x-4+4 = 90+4

3x = 94

Dividing both sides by 3

3x/3 = 94/3

x = 31.33°

x ≈ 31.3°

Answer:

28.7

Profit % = (Profit/C.P)*100

= (1000/8000)*100

= 12.5%

Step-by-step explanation:

Cp of 1000glass =8000

100were broken =8000-800=7200

now there were 900 glass tumblers left he sold at rs10 each =9000

Answer:

8, 16, 26

Step-by-step explanation:

1 squared + (5*1) + 2 = 8

2 squared + (5*2) + 2 = 16

3 squared + (5*3) + 2 = 26

Hope it helps !

Answer:

8, 16, 26

Step-by-step explanation:

To find the first 3 terms substitute n = 1, 2, 3 into [tex]T_{n}[/tex] , that is

[tex]T_{1}[/tex] = 1² + 5(1) + 2 = 1 + 5 + 2 = 8

[tex]T_{2}[/tex] = 2² + 5(2) + 2 = 4 + 10 + 2 = 16

[tex]T_{3}[/tex] = 3² + 5(3) + 2 = 9 + 15 + 2 = 26

Answer:

  0.50

Step-by-step explanation:

"Cents" generally refers to 1/100 of something. When it is money, it refers to 1/100 of the base unit of the currency. When it is land area, it refers to 1/100 of an acre.

__

In the US, 50 cents means 50/100 dollars, or $0.50.

In Europe, 50 cents means 50/100 euros, or €0.50.

In general 50 cents is 50/100 = 0.50.

Answer:

-7/4 =x

Step-by-step explanation:

x-2(x+3) = 4(2x+3) -(x+4)

Distribute

x -2x -6 =8x+12 -x -4

Combine like terms

-x-6 = 7x +8

Add x to teach side

-x-6 +x = 7x+x+8

-6 = 8x+8

Subtract 8 from each side

-6-8 =8x+8-8

-14 = 8x

Divide by 8

-14/8 = 8x/8

-7/4 =x

Answer:

Step-by-step explanation:

[tex](x + 3) = 4 (2 x + 3)- (x + 4)\\Ope- the- brackets\\x+3 = 8x +12-x-4 \\Collect- like- terms\\x-8x+x=12-4-3\\-6x =5\\Divide-both-sides-by -6\\\frac{-6x}{-6} =\frac{5}{-6} \\x =-5/6[/tex]

Answer:

43

Step-by-step explanation:

90 is on a straight line with an interior angle of the triangle. So, they add to 180. 90+x=180

x=90

133 is also on a straight line. 180-133= 47

47+90=137

that leaves p as 180-137 or 43.

Answer:

number of half gallons of ice cream the store bought=90 half gallons

Step-by-step explanation:

given data

bought ice cream = $2.30 per half gallon

one freezer malfunctioned and ruined  = 14 half gallons

ice cream is sold = $4.00 per half gallon

profit = $97.00

solution

we know here profit is express as

Profit = Money earned - Money spent       ...................1

and we consider here total number of gallons bought  = x

so Money earned =  $4(x-14)

Money spent   = $2.30(x)

so put here value and we get

$97 = $4(x-14) - $2.30(x)  

solve it we get

x = 90

so number of half gallons of ice cream the store bought=90 half gallons

Answer:

x ≠ 1.

Step-by-step explanation:

In mathematics, anything divided by 0 is null. It is not valid. And so, in this case, x - 1 must never equal 0, but it can be any number other than 0.

x - 1 = 0

x = 1

That means that the domain of the function is x ≠ 1.

Hope this helps!

The value of domain is,

⇒ {- ∞, ∞} - {1}

A relation between a set of inputs having one output each is called a function. and an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).

Given that;

The function is,

⇒ y = 3 / (x - 1)

Now, We can find the domain as;

Here, The function is,

⇒ y = 3 / (x - 1)

Hence, Domain is,

⇒ {- ∞, ∞} - {1}

Thus, The value of domain is,

⇒ {- ∞, ∞} - {1}

Answer: B

Step-by-step explanation:

The probability of winning when playing regular defense is 42 over the total 50.  

42/50 = 0.84

The probabilty of also winning when playing Prevent defense is 35 over the total 50 also.

35/50 =  0.70  

0.84 is greater than 0.70 so your more likely to win playing regular defense.

B. P(win | regular) = 0.84

    P(win | prevent) = 0.70

    Conclusions : You are more likely to win by playing regular defence.

The ratio of favourable outcomes of an event and total outcomes of an event is called probability of that event.

The number of outcomes of winning by regular defence is 42 out of 50.

∴ P(win | regular) = 42/50 = 0.84

The number of outcomes of winning by prevent defence is 35 out of 50.

∴ P(win | prevent) = 35/50 = 0.70

Conclusion : You are more likely to win by playing regular defence.

Hence the option B is correct.

Hey there! :)

Answer:

19 units.

Step-by-step explanation:

The sides of a Rhombus are all congruent. Therefore:

x + 10 = 3x - 8

Subtract both sides by x:

10 = 2x - 8

Add 8 to both sides:

18 = 2x

Divide both sides by 2:

18/2 = 2x/2

x = 9.

Find the side length by plugging x into an equation:

(9) + 10 = 19 units.

Answer: x=14

Step-by-step explanation: The total is 180 degrees. The right angle is 90, the given angle is 76, so x is 14.
