Step-by-step explanation:

William has a sticker album.

We are told in the question that:

Some pages have 1 sticker on them, and other pages have 2 stickers on them. If William has 18 stickers

The many different ways that can he put the stickers in the album is calculated as:

18 stickers ÷ ( 1 stickers + 2 stickers)

= 18 ÷ 3

= 6 ways

Therefore, the different ways that he can put the stickers in the album is 6 ways

Answer:

? = 109 degrees

Step-by-step explanation:

180 -45-75 = 60

180-60-79 = 41

180-41-60 = 71

180-71 = 109 degrees

Step-by-step explanation: there are 4 quarts in a gallon and we can see by adding the mango juice, there will be no space!

Water (2 quarts) mango juice (2 quarts) equals a gallon

Ginger ale = one gallon

That’s already 2 gallons and we still have the 2 pints of pineapple juice!

Answer:

72cm²

Explaination:

2(2*3)+2(2*6)+2(3*6)=72cm²

Answer:

g(x) = |x + 4| - 2

I recommend next time you try substituting the x-values from points the line meets into each function until g(x) matches the y-value. For example, the line/function passes through the point (1, 3).  Substitute the x-value: 1 into the function where it says x. That would give you 3 = |1 + 4| - 2. (If you're wondering where I got 3 from g(x) is basically the same as y. Simplify the values in the "||" first. You should then get 3 = 5 - 2. Simplify that and you get 3 = 3 which means g(x) = |x + 4| - 2 is the correct answer. If you were to get anything else other than 3 such as "3 = 4", it would not be correct.

Answer:

5 hours

Step-by-step explanation:

use the variable "h" for number of hours

10+5h=7h

subtract 5h from both sides

2h=10

divide both sides by 2

h=5

Answer:

x=0

Step-by-step explanation:

substitute y=0

0= -x^2

then swap the sides

-x^2=0 ,

change the signs

x^2=0

set the base equal to 0

x=0

Answer:

x=-14, y=13

Step-by-step explanation:

4x+5y=9

x+3y=25

4x+5y=9

-4x-12y=-100

-7y=-91

y=13

Subsitute: x+3(13)=25

x=-14

This is worded weirdly I assume it means there is a slope of one. Also, I hate that you got the points for this question by putting nonsense "answers" on questions, but you seemed like a halfway decent person.

Answer: £180

Step-by-step explanation:

The interest gotten for the 10 years will be calculated as:

= Principal × Rate × Time

= 150 × 2% × 10

= 150 × 0.02 × 10

= 30

The amount he has in the bank account at the end of the 10 year will be:

= Principal + Interest

= £150 + £30

= £180

Answer:

125%

Step-by-step explanation:

Divide 346.25 by 277

you get 1.25

multiply it by 100

Answer:

25%

Step-by-step explanation:

This is calculated this way:

$346.25/$277 = 1.25

Then subtract 1, because that part represents what Tessa had to start with. That leaves

0.25

That decimal equals 25%, and that is the answer.

Answer:

21°

Step-by-step explanation:

<DCB = 3x + 8°

< DAB = 5x + 4°

Now

<DCB + <DAB = 180° { being opposite angles of cyclic quadrilateral }

3x + 8° + 5x + 4° = 180°

8x + 12° = 180°

8x = 180° - 12°

8x = 168°

x = 168° / 8

Therefore x = 21°

Option C us correct, (D₂oR x-axis)(ΔLMN)  best describes the composition of transformations that maps ΔLMN to ΔL'M'N

Graph is a mathematical representation of a network and it describes the relationship between lines and points.

We have to find the composition of transformations that maps ΔLMN to ΔL'M'N.

Two triangles are said to be similar if their corresponding angles are congruent and the corresponding sides are in proportion .

Graph transformation is the process by which a graph is modified to give a variation of the proceeding graph.

The graphs can be translated or moved about the xy-plane.

A translation is a movement of the graph either horizontally parallel to the x-axis or vertically parallel to the y-axis.

As we observe the graph dilation and reflection applied to triangle LMN to get triangle L'M'N'.

A dilation is a transformation which preserves the shape and orientation of the figure, but changes its size.

(D₂oR x-axis)(ΔLMN) is the transformations that maps ΔLMN to ΔL'M'N.

Hence, Option C us correct, (D₂oR x-axis)(ΔLMN) is the transformations that maps ΔLMN to ΔL'M'N.

Answer:

23/100

Step-by-step explanation:

Given the decimal value 0.23, to write as a fraction;

0.23 = 23/100

The place value of dot will be replaced as 1 at the denominator and since the decimal is in 2 decimal places, two zeros will be added to after the 1 to make it 10 thereby making the required fraction 23/100.  Hence the value of 0.23 as a fraction will be 23/100
