Does adding zero to a number ever change its value? what is this property called?

Answers

No Additive identity/zero property of addition In math there are several identity properties for the various function. These are special values that when the operation is done using those values, the result will be the value you started with. For addition, that special value is zero. Adding zero to any value will result in the original value. Hence, zero is the additive identity value.

If the highest score in a distribution is x = 16 and the lowest is x = 4, then the range is 12 or 13 points.
a. True
b. False

Answers

True. The interval between the lowest and highest scores (including the lowest and highest) is the range. 

The range in the given scenario is only 12 points, not 12 or 13 points as mentioned.

False

Range = Highest score - Lowest score

Range = 16 - 4 = 12

Therefore, the range can only be 12 points.

What is the conclusion in this conditional statement?

If a square has a perimeter of 8 units, then its sides have a length of 2 units each.
the square has a perimeter of 8 units
the sides of the square have a length of 2 units each
Submit



Answers

Final answer:

The conclusion in the given conditional statement is that the sides of the square have a length of 2 units each. This is deduced from the formula for the perimeter of a square (P = 4 × side length), and the given perimeter of 8 units.

Explanation:

The conclusion in the conditional statement "If a square has a perimeter of 8 units, then its sides have a length of 2 units each" is the sides of the square have a length of 2 units each.

In a conditional statement, the "if" part is known as the hypothesis and the "then" part is the conclusion. Given that a square's perimeter is the sum of the lengths of all four sides, we can show this through an equation: P = 4 × s, where P represents the perimeter and s the length of one side. Since the perimeter is given as 8 units, we can solve for s by dividing the perimeter by 4: 8 units = 4 × s, which simplifies to s = 2 units. Therefore, each side of the square must be 2 units long.

Final answer:

The conclusion in this conditional statement is that the sides of the square have a length of 2 units each.

Explanation:

The conclusion in this conditional statement is:

The sides of the square have a length of 2 units each.

In a conditional statement of the form 'if A, then B', the conclusion (B) is the statement that follows 'then'. In this case, the conclusion states that the sides of the square have a length of 2 units each.

Answer:

The required equation is [tex]S+0.2t=p[/tex]

Step-by-step explanation:

Consider the provided equation.

[tex]S=p-0.2t[/tex]

We need to solve the equation for p.

Isolate the variable as shown.

Add 0.2t from both sides.

[tex]S+0.2t=p-0.2t+0.2t[/tex]

Hence, the required equation is [tex]S+0.2t=p[/tex]

The standard recommendation for fluid needs is 30 ml/kg body weight. parker weighs 67 kg. how many cups of fluid will he need? (give your answer to the nearest tenth. give only the value. do not write the word cup or its abbreviation.)

Answers

Well First you multiply 67 kg, which is how much parker weighs, by 30. 30ml/kg means that there is 30ml for ever 1 kg and parker weighs 67. So Parker needs 2010 ml of fluid and the last thing you need to do is convert 2010 ml into cups. 1ml =.00423 cups. So you multiply 2010 by .00423 and you'd have you're answer. 8.5

Mary invests £12000 into a savings account. The account pays 1.5% compound interest per year

Answers

Mary will earn $1800 of interest each year 

Answer:

Value of her investment after 2years is £12,362.7

Step-by-step explanation:

The question is incomplete, here is the complete question.

"Mary invests £12000 in a savings account. The account pays 1.5% compound interest per year. Work out the value of her investment after two years"

Using the relationship:

A = P(1+r/100)^n

Where P is the principal = amount invested = £12000

r is the compound interest = 1.5%

n is the time = 2years

A is the amount compounded after n years

A = 12000(1+1.5/100)²

A = 12000(1+0.015)²

A = 12000(1.015)²

A = 12000(1.03)

A = 12362.7

Value of her investment after 2years is £12,362.7

Can somebody help me with this one?

Answers

s = sale price (in dollars)
p = sticker price (in dollars)
Note: the sticker price is what the customer pays after the discount
Another note: This is ignoring any taxes or other fees

We're told that the sale price is the result of taking 10% off the sticker price. This means...

sale price = (sticker price) - (10% of sticker price)
s = p - 0.10*p
s = 1*p - 0.10*p
s = (1 - 0.10)*p
s = (0.90)*p
s = 0.90*p

So the expression for the sale price is 0.90*p where p is the sticker price in dollars.

Note: this means that the sale price is 90% of the sticker price.

----------------------------------------

Now plug in the sticker price p = 80 to find the sale price s
s = 0.90*p
s = 0.90*80
s = 72

The sale price is $72 which is what the customer will pay (if we ignore any taxes or other fees).

The floor of a conference hall can be covered completly with tiles.Its length is 36ft. longer than its width.The area of the floor is less than 2040square ft.How would you represent the with of the floor?How about its lenght?What mathematical sentence would represent the given situation?What are the possible dimensions of the floor?How about the possible areas of the floor?Would it be realistic for the floor to have an area of 144sq.ft?Explain your answer.

Answers

Let's start by defining a few variables:
x=width of the floor
x+36= length of the floor 
Since area = length x width, we can write the equation:
x(x+36)<2040 ft² (this is your mathematical sentence
Make a chart of the possible values:
x  | x+36|  Area
30   66  = 1980  fits
31   67  = 2077 *too big
So, all dimensions with length smaller than 30 and widths smaller than 66 fit the system. 
x(x+36)=144? Let's try smallest numbers - width of 1 ft, length of 37 ft
1(37)=37 too small
3(39)=117 nope
4(40)=160 nope
So, no, 144 ft² is not a realistic answer.



L < 66; The length of the floor will be less than 66feet

W<30; The width of the floor will be less than 30feet

The possible area of the floor is 1885 sq. ft

Since 144 sq.ft ≠ 1885feet², hence it would not be realistic for the floor to have an area of 144sq.ft

The formula for calculating the area of the conference floor is expressed as:

A = LW

L is the length

W is the width

If the length is 36ft. longer than its width, hence;

L = W+36

Since the area of the floor is less than 2040 square feet, hence;

A < 2040

LW < 2040

(W+36)W < 2040

W² + 38W < 2040

W² + 38W - 2040 < 0

W² + 68W - 30W - 2040 < 0

W(W+68)- 30(W+68)< 0

(W-30)(W+68) < 0

W - 30 < 0 and W < -68

W < 30

Since the width cannot be negative, hence the width of the floor will be less than 30feet

Since L = 36 + W

L < 36 + 30

L < 66feet

The length of the floor will be less than 66feet

The possible dimensions area 29feet by 65feet since the width is less than 30 and the length is less than 66feet.

Get the possible area:

Possible area = 29 × 65

Possible area = 1885feet²

Since 144 sq.ft ≠ 1885feet², hence it would not be realistic for the floor to have an area of 144sq.ft
