(i) Pairs of neighboring angles are supplementary and opposite angles have the same measure.

(ii) The two angles formed by a line coming out of another line are supplementary.

(i) When two straight lines pass through each other, then two pairs of opposite angles are constructed. A pair with angles of [tex](3\cdot x + 52)^{\circ}[/tex] and another pair with angles of [tex](2\cdot x + 2)^{\circ}[/tex], each pair of angles with different measures are supplementary.[tex]\blacksquare[/tex]

(ii) When a straight line comes out of another straight line, from a point distinct to any endpoint of the former, then we construct two supplementary angles. The largest angle has a value of [tex](10\cdot x + 20)^{\circ}[/tex], whereas the smaller one has a value of [tex](6\cdot x + 8)^{\circ}[/tex]. [tex]\blacksquare[/tex]

Answer:

  not similar; corresponding sides are not proportional

Step-by-step explanation:

If the triangles were similar, corresponding sides would be proportional. That is, you would have ...

  AX/AB = AY/AC

Here, those ratios are ...

  6/24 ≠ 10/35

so, the corresponding sides are not proportional, and the triangles are not similar.

Answer:

Step-by-step explanation:

m ∠ 1 = 42 °

m ∠ 2 = m ∠ 4 = m ∠ 9 = m ∠ 12 = ( 180° - 62° - 42° ) = 76 °

m ∠ 3 = m ∠ 6 = m ∠ 7 = 62 °

m ∠ 5 = m ∠ 8 = ( 180° - 62° ) = 118 °

Answer:   3 mol of O₂

Solution:

The Balance chemical equation is as follow,

                               2 KClO₃    →    2 KCl  +  3 O₂

According to this equation on decomposition 2 moles of Potassium chlorate (KClO₃) produces 2 moles of Poatassium chloride (KCl) and 3 moles of oxygen gas (O₂).

Therefore, when,

                    2 moles of KClO₃ produces  =  3 moles of O₂

So,

                 2 moles of KClO₃ will produce  =  X moles of O₂

Solving for X,

                    X =  (2 mol × 3 mol) ÷ 2 mol

                   X  =  3 mol of O₂

Using above method you can calculate any amount of O₂ or KCl produced by decomposing any amount of KClO₃.

Answer:

3 mol of O₂

The expressions that are equivalent to 4 × -3 are A) -12 and C) 2 × -6.

Algebraic expressions are mathematical statements with a minimum of two terms containing variables or numbers.

Option A is a straightforward multiplication of 4 and -3, which gives -12.

Option C (2 × -6) is equal to -12.

Option B can be simplified as follows: (-4) - (-4) · (-4) = (-4) - 16 = -20.

Therefore, option B is not equivalent to 4 × -3.

Option D is equal to 1/64.

Option E is equal to 1.

Option F is equal to 2, and option G is equal to 12.

Options B, D, E, F, and G are not equivalent to 4 × -3.

  10 mm = 1 cm

Step-by-step explanation:

10 mm = 1 cm

__

The SI prefix "milli-" means 1/1000. The prefix "centi-" means 1/100. Consequently 1 cm = 0.010 m and 1 mm = 0.001 m.

There are 10 mm in 1 cm.

Answer:

120 history textbooks

Step-by-step explanation:

Physics textbooks = 3 times the amount of history textbooks

History textbooks = x

Physics textbooks = 3x

480 = x + 3x

= 4x

480/4 = x

x = 120

The equation 60.1 = 7.2x + 2.5 can be used to find the number of oranges in the bag is 8.

It is a system of an equation in which the highest power of the variable is always 1. A one-dimension figure that has no width. It is a combination of infinite points side by side.

Given

A grocer sells oranges in bags. Each empty bag weighs 2.5 ounces and each orange weighs 7.2 ounces.

Khalil buys a bag of oranges that weighs 60.1 ounces.

Let x be the number of oranges.

Then the equation will be

y = 7.2x + 2.5

For y = 60.1, the value of x is

[tex]\rm 60.1 = 7.2x + 2.5\\[/tex]

On simplifying, we have

x = 8

Thus, the number of oranges in the bag is 8.

Answer:

C

Step-by-step explanation:

So if we look at the information that we already know, Layla's reading to months ratio is, 6:2. But to find out the equation we want to find out how many books she reads in ONE month instead of two.

Divide 2/2, and for ratios if you divide one side you have to do the same thing to the other side, so we get, 3:1. Where Layla reads 3 books per 1 month.

Therefore the answer is C.

If we wanted to double check our answer we could substitute our information back in:

6=3×2

6=6

Since the equations equal each other, we know we got it correct.

Answer:

1a. 58/99

1b. 53/90

1c. 29/50

Step-by-step explanation:

let's start with the easiest one

1.(c)

0.58 = 58/100 = 29/50

that is the simplest possible form, as 29 is a prime number and not a factor of 50.

1.(a)

0.585858585858... = 58×0.0101010101010101...

now, we know that 1/"double digit" (like 1/22) mostly produces a repeating pattern with a period length of 2 after the decimal point.

and we find

1/99 = 0.01010101010101...

so, our solution is

58 × 1/99 = 58/99

that is the simplest possible form, as 58 and 99 do not share any factors.

1.(b)

0.5888888888888... = 0.5 + 0.0888888888888... =

= 0.5 + 8×0.01111111111111... = 0.5 + 8×1/10 × 0.1111111111...

we know how to create 0.11111111111... :

1/9 = 0.111111111111111...

so, our solution is

0.5 + 8 × 1/10 × 1/9 = 0.5 + 8/90 = 5/10 + 8/90 =

= 45/90 + 8/90 = 53/90

this is the simplest possible form, as 53 is already a prime number and not a factor of 90.
