Answers

Answer 1

The set {126, 168, 189} has  21 as a common factor.

The set{154, 231} has  11 as a common factor.

Common factor:

If a number m is completely divisible by number n. Then number n will be the one factor of number m.

(a). Given set of number is, {126, 168, 189}

Now check,  21 is a common factor or not.

 [tex]\frac{126}{21}=6,\frac{168}{21}=8,\frac{189}{21}=9[/tex]

It is observed that all numbers are completely divisible by 21.

So that , 21 is common factor.

(b). Given set of number is, {154, 231}

      [tex]\frac{154}{11}=14,\frac{231}{11}=21[/tex]

It is observed that all numbers are completely divisible by 11.

27. Alla angles must equal 360 so 101+101=202 360-202=158/2=79

28. Intersecting equal sides

29. Opposite sides p=5 and  since q-3=6 then q=9

Step-by-step explanation:

The two tangents from a point are the same length.

  RS = RT

  y = y^2/2

  y^2/2 -y = 0

  y(y/2 -1) = 0 . . . . factor out y

Values of y that make these factors zero are ...

  y = 0 . . . . . . . . true if points R, S, T are coincident on the circle

Step-by-step explanation:

We have the number 91 and are asked to round to the nearest 100.

When we round to a certain number, we always have to look at the number to the right of the place value being rounded to, if the numbers is 0-4, you will round down, if the number is 5-9, you round up.

Right now we have 094, 0 being the hundreds place, look to the right and see that we have 9. Therefore we round up.

Answers

First find the lowest common multiple of the denominators which are 12 3 9 and 27 these all go into 108. Next divide 108 by the original denominators for example 108/12 is 9 then times 9 by the numerator which is 5 and you get 45 so the first one is 45/108. Do this for them all and order by the size of the numerator

Answers

Attached is the complete question with the semi circular design.

Answer:

9.8 m²

Step-by-step explanation:

From the image, we can see that;

Diameter = 5 m

That means radius; r = 5/2 = 2.5 m

Now, formula for area of semi circle is;

A = ½πr²

A = ½ × π × 2.5²

A = ½ × 22/7 × 6.25

A ≈ 9.8 m²

Area of semi circular lawn = 9.8 m²

What is the slope of y = -4?

Answers

Answer:

0

Step-by-step explanation:

The line is horizontal.

Answer:   slope = 0

Explanation:

Think of y = -4 as y = 0x+(-4)

We see that the equation matches the form y = mx+b

m = 0 = slope

b = -4 = y intercept

Side note: this equation graphs out a horizontal line. All horizontal lines have a slope of 0.

Answer:

Answer: B, 6/11

Step-by-step explanation:

Well we know that 3+2+1=6+3=9.

So that means we will add the 2 brown crayons to the denominator.

The denominator before we added 2 to it, it was 9 as a common denominator. If we want to get the common numerator we are going to have to add the top and that will become 9 then you will have to subtract that by 3

6/11 is also the smallest number that you can get.

You can turn the fraction into a decimal and have it that way to make it easier.

When you turn a fraction into a decimal the number is always the same but with comparing numbers it is a lot easier to do than comparing fractions
