Step-by-step explanation:

Answer:1. distributive property

2. commutative property (the order of 8x and -24 is swapped)

3. reflexive property ((8-24) = -16; -16 is substituted for 8-24. I prefer "substitution property".)

4. commutative property (the order of 8x and -16 is swapped)

5. distributive property

Question: Write these numbers in order of size. Start with the smallest number. 3/7,41%, 0.45.

This is EASY! Here's your answer, hope it helps:

0.45, 3/7, 41%

Step-by-step explanation:

0.45 is first because it is the smallest percentile what i mean by this is anything with a point or anything with the number 0 comes first.... IF THE NUMBER 0 IS THE FIRST NUMBER OF THE NUMBER CHARACTERISTIC!

Why this is true? Well depending on your grade if you know your numbers... 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22... and so on. (You should know this if you are being asked this question). The rest are as simple as this.

3/7 comes next (the second highest number). How i know this is by reviewing the number chart listed above coming as the third highest number starting from 1 (1, 2, 3)

Lastly 41% is the last number/percentile. Which in conclusion on the number chart, YES! you cant find it because i stoped at number 22 and for your correct answer the number 41 is 19 numbers away from 22 which gives me the answer that the correctness to this question and format would be that 41% is the last number to this question.

If you have any more question over why i found this to be the correct answer please ask i will be glad to assist you. Thank you and have a great day!

Answer:

41%, 3/7, 0.45

Step-by-step explanation:

41% = 0.41

3/7 = ~0.43

0.45 =...0.45

Answer:

2 sessions for tennis and 1 for the other tennis club which would make it 60 each. 30 x 2 = 60 and 48 + 22 = 60

Answer:

A) 0.8 X 3 X 1 = 2.4

B) 0.3 X 2 X 4 = 2.4

C) 0.4 + 1.5 +0.5 = 2.4

D) 2 + 0.3 + 0.1 = 2.4

Step-by-step explanation:

A) To get three numbers whose product is 2.4, we will have to find out by multiplying three different decimal numbers to see if we can get 2.4. In other words, we are looking for factors of 2.4.

We can start by dividing 2.4 by three.

This will give 0.8 ( which is one of the numbers)

Recall that 1 is also a number and any number multiplied by 1 is itself. We can take one to be our third number.

Our three numbers are 0.8 X 3 X 1 = 2.4

B) To get another set of numbers, we can simply choose to divide 2.4 by 4.

2.4 / 2 = 0.6.

we can also divide 0.6 into 2.

0.6 / 2 = 0.3

Our other three numbers can be 0.3 X 2 X 4 = 2.4

C) Three numbers which can sum up to 2.4 are

0.4 + 1.5 +0.5 = 2.4

D) To get another set of numbers, we can simply break 2.4 up into other simpler numbers.

2 + 0.3 + 0.1 = 2.4

Answer:

The answer is A

      Coordinates of the points B, C and D will be (4, -3), (-2, -3) and (6, 3) respectively.

            Rule for the transformation will be,

            P(x, y) → P'(-x, -y)

            Rule for the transformation will be,

            P(x, y) → P'(x - a, y + b)

            Rule for the transformation will be,

            P(x, y) → P'(-x, y)

By using these rules,

"If a point A(-4, 3) is rotated 180° about the center (0, 0)"

Rule for the transformation,

P(x, y) → P'(-x, -y)

A(-4, 3) → B(4, -3)

"If a point A(-4, 3) is translated 2 units right and then reflected across x-axis."

Rule for the transformation,

P(x, y) → P'[(x + a), -y]

A(-4, 3) → C[(-4+2), -3]

            → C(-2, -3)

"If a point A(x, y) is reflected across y-axis, then translated by 2 units to the right"

Rule for the transformation,

P(x, y) → P'[(-x + a), y]

A(-4, 3) → D[(4 + 2, 3]

            → D(6, 3)

    Therefore, coordinates of the points B, C and D will be (4, -3), (-2, -3) and (6, 3) respectively.

C. Natasha has been charged by $1.85 for her purchase.

Step-by-step explanation:

Natasha has been over charged by $1.85 for her purchase. The correct option is - c. Natasha has been over charged by $1.85 for her purchase

From the question, we are to determine if Natasha has been billed correctly for her purchase

From the given information,

She purchased  

3 hard cover books for $19.95 each

3 × $19.95 = $59.85

and

1 book on tape for $17.43

1 × $17.43 = $17.43

Total purchase = $59.85 + $ 17.43

= $77.28

But, the site says that taxes paid by the customer are 7.25% of the total purchase price

∴ The tax Natasha would pay = 7.25% × $77.28

= 0.0725 × $77.28

= $5.60

Add to the total purchase,

Present bill = $77.28 + $5.60

Present bill = $82.88

Then, she selects standard shipping.

According to the shipping charges,

For amount of purchase between $50 - $100, Standard shipping costs $6.35

∴ Total bill = $82.88 + $6.35

Total bill = $89.23

But, the company bills her credit card $91.08

Since, $91.08 is more than her total bill, $89.23, then, Natasha has been over charged.

$91.08 - $89.23 = $1.85

Hence, Natasha has been over charged by $1.85 for her purchase. The correct option is - c. Natasha has been over charged by $1.85 for her purchase.

Answer:

The height of the lamp is  18.33 ft

Step-by-step explanation:

We can think in two triangle rectangles, one with cathetus of:

5.5ft and 6ft (the one formed by the woman ad her shadow)

And another triangle with cathetus equal to:

6ft + 14ft (the distance between the end of the shadow and the lamp)

And the other cathetus is the height of the lamp, H.

As bot triangles will share an angle (the one formed by the end of the shadow and the hypotenuse) then the triangles are equivalent, so the quotient between their cathetus will be equal, this is:

H/(6ft + 14ft) = 5.5ft/6ft

H/(20ft) = 5.5ft/6ft.

H = (5.5ft/6ft)*20ft = 18.33 ft

Answer:

1 and 3 are irrational!!! The others are all rational

Step-by-step explanation:

1 and 3 are never terminating and they are not repeating, therefore, they are irrational! All the others are either terminal (they have a decimal that stops) or they are repeting and those repeting numbers can be written as a fraction, for example 0.2222... can be written as 2/9

Answer:

3x+8-2(1-x)=1

First, multiply 2x1 and 2x-x

3x+8-2+2x=1

Then rearrange the terms

3x+2x+8-2=1

Then combine like terms

5x+6=1

Then subtract 6 on both sides

5x=-5

Then divide 5 on both sides

x=-1

Step-by-step explanation:

Value of x = -1

when any mathematical values are made equal with help of some variables and constant.

Given equation 3x + 8 - 2(1-x) = 1

simplify equation 3x + 8 - 2 +2x = 1

5x + 6 = 1

5x = 1 - 6

5x = -5

x = -1

Hence x = -1
