Answer:

The second one between 2 and 3

Step-by-step explanation:

Sq root of 7 = 2.65

Answer:

2nd number line represents √7 best

Step-by-step explanation:

Method 1

√7 ≈ 2.65

Therefore, the 2nd number line represents √7 best

(the one with the dot between 2 and 3)

Method 2

√1 = 1

√4 = 2

√9 = 3

Therefore, as √7 is between √4 and √9, the solution is somewhere between 2 and 3.

Answer:

The true statements about the sample described in the scenario above are:

The sample should be larger to give more reliable information.

The sample size is too small to represent the population.

The sample size is too small and can lead to false inferences.

Step-by-step explanation:

The sampling technique employed is a systematic random sampling where samples are chosen at every specified interval. Hence, the sample is randomly selected.

The area of a cube-shaped present in a box Lainley wraps is A. 81 in²

A cuboid is a three-dimensional closed figure which has volume along with surface area.

The volume of a cuboid is the product of its length, width, and height.

The total surface area of a cuboid is 2(lw + wh + wl) and the lateral surface area is 2(l + w)×h.

Given, A box that has a volume of 729 inches.

First we'll prime factorize 729.

729 = 3×243 = 3×3×81 = 3×3×3×3×3×3.

If we take the cube root of 729 it would be 3×3 = 9.

So, It is a cube with a side length 9.

Now, We know area of a cube is side².

Therefore, The area of this cube is 9² = 81 in².

Answer:

if m∠1 = 30° then m∠3 = 30° as they are parallel to each other and that is why they will have same angles.

therefore m∠3 = 30°

extra's:

→ m∠2 = m∠4 =

→ (360-30*20)/2

→ 150°

...............................

See here

m<1 and m<3 are opposite angles to eachother.

And we know that opposite angles are equal

Answer:

The factors are x-3 and x+2, and the roots are 3 and -2.

Step-by-step explanation:

x^2-x-6 can be factored in the following way:

(x-3)(x+2)

The factors are x-3 and x+2, and the roots are 3 and -2.

Factored form of an expression is writing it in the terms of multiplication of factors. The factors of given expression are: (x-3) and (x+2)

Quadratic polynomial with single variables are expressible in the form

[tex]ax^2 + bx + c[/tex]

where x is the variable and a,b,c are constants.

Its factored form is

[tex]\dfrac{1}{4a^2} \times (2ax +b-\sqrt{b^2 - 4ac})(2ax +b+ \sqrt{b^2 - 4ac})[/tex]

For the given case, the expression given to us is [tex]x^2 - x - 6[/tex]

Comparing it with the standard form of quadratic expression  [tex]ax^2 + bx + c[/tex], we get: a = 1. b = -1. and c = -6

Using the aforesaid formula, we get:

[tex]=\dfrac{1}{4a^2} \times (2ax +b-\sqrt{b^2 - 4ac})(2ax +b+ \sqrt{b^2 - 4ac})\\\\=\dfrac{1}{4}\times(2x -1 - \sqrt{1 +24})(2a -1 + \sqrt{1 + 24})\\\\=\dfrac{1}{4} \times (2x - 1-5)(2x - 1 + 5)\\\\=(x -3)(x+2)[/tex]

Thus, The factors of given expression are: (x-3) and (x+2)

Answer:

32;35

Step-by-step explanation:

a+b=67

a-b=3 => a=3+b

=>instead of a we write 3+b =>

a+b=67 => 3+b+b=67 => 2b=64 => b=32

=> a = 3+b=> a=32+3=35

Answer:

B

Step-by-step explanation:

This is a really simple topic. All you need to do when seeing these ordered pairs is see which has x-values that don't repeat. Over here, we can see that that is B, so B is the correct option.

3x+13=3(x+6)+1
Expand:

3x+13=3x+18+1
Simplify:

3x+13=3x+19
Subtract 13 from both sides:
3x+13-13=3x+19-13
Simplify:

3x=3x+6

Subtract 3x from both sides:
3x-3x=3x-3x+6

0=6

Since the sides are not equal there are no solutions to this problem

Answer: 40 kilometers

Step-by-step explanation: Since the word ratio is cm/km (centimeter/kilometer), and the number ratio is 2/5, you will have to create another set and put the 16 cm next to the 2 cm. So it would be 2/5=16/X. Now you have to find the value of x. First, you have to multiply 5 by 16, which is equal to 80. Now you divide it by 2 and you will get 40 kilometers as your final answer.
