Answer:

35

Step-by-step explanation:

Let's call the original price X

14% of x is equal to $4.90 to calculate 100% of the price we multiply 100 with 4.9 then divide it with 14

4.9 × 100 ÷ 14 = 35

Answer:

0.72321

Step-by-step explanation:

Given that :

Mean = 21604

Standard deviation (s) = 727

Sample size (n) = 193

P(x < 21635) :

USing the relation to obtain the standardized score (Z) :

Z = (x - m) / s/√n

Z = (21635 - 21604) / 727/√193

Z = 31 / 52.330605

Z = 0.5923875

P(Z < 0.5924) = 0.72321 (Z probability calculator)

p(Z < 0) = 0.5 ( Z probability calculator)

Answer:

The values of x are 0 and -4.5

Step-by-step explanation:

To find the inflection point, we simply find the second derivative

Mathematically, that will be calculated as follows

1st derivative

10x^4 + 60x^3

2nd derivative

40x^3 + 180x^2

Equate these values to zero

40x^3 + 180x^2 = 0

x^2(40x + 180) = 0

x^2 = 0

or 40x = -180

x = 0

or x = -180/40 = -4.5

Answer:

1068

Step-by-step explanation:

Step-by-step explanation:

Since area = length(width) = l(w)

We need to multiply 15 and 9.

15(9) = 135

Therefore, the area of the rectangle is 135 ft

Area of the rectangle is 135 feet square

A rectangle is a quadrilateral with four right angles.

Area is the quantity that expresses the extent of a region on the plane or on a curved surface

Given,

Length of the rectangle = 15 feet

Width of the rectangle = 9 feet

Area of the rectangle = Length × Width

=15×9

=135 feet square

Hence, the area of the Rectangle is 135 feet square

Answer:

Step-by-step explanation:

All that making a list does is creates a visible step by step instruction manual on what needs to be done in order to solve the math problem that needs to be solved. Lists are extremely helpful and can be used in every single math problem, for example....

15x - 25 = 275

See making a list isolates the problem into an easy to read instruction manual.

Answer:

Step-by-step explanation:

Supplementary angles are two or more angles that add up to give the measure of angle on a straight line (i.e [tex]180^{o}[/tex]).

It can be deduced from the given question that;

1. <1 and <2 are supplementary, also <1 and <3 are supplementary. Reason: as given in the question.

2. Given statements: m<1 + m<2 = [tex]180^{o}[/tex], and m<1 + m<3 =  [tex]180^{o}[/tex]. The reason is the definition of supplementary angles.

3. Statement: m<2 = m<3. The reason is a transitive property.

4. Statement: m<1 + m<2 = m<1 + m<3. The reason is subtraction property of equality.

5.Given statement: <2 ≅ <3. The reason is that definition of congruent angles.

Therefore, <2 ≅ <3.

Answer:

$0.72

Step-by-step explanation:

In order to solve this question we need to know that 1% is one hundredth of something. Another important thing you need to understand is that when we are trying to find n% of y  we multiply just need to multiply "y" by [tex](\frac{n}{100} )[/tex]. In our case we have to find 6% of 12, in other word they are asking as the following "What is $12 times [tex](\frac{6}{100} )[/tex]?". So in order to find the answer we do the following..............

[tex]12 (\frac{6}{100} ) = \frac{(12)(6)}{100} = \frac{72}{100} = 0.72[/tex]

Answer:

A person's age and height

Step-by-step explanation:

Select which do not represent proportionality

Proportionality exists when a unit rate can be calculated.

For instance:

- If 2 litres of gas is $2, then the unit rate is $1 per litre

- If an employee is paid $100 for 5 days, then the unit rate is $20 daily

- If 5 movie tickets cost $50, then the unit rate is $10 per movie

The above scenario are used to describe options (2 - 4) because they can be expressed in unit rates.

However, this is not the same for age and height because age is not a function of height and height is not a function of age. In other words, they can not be expressed in proportions.

So, option (a) is not a situation of proportionality.

The value of g(1) is 2 because the graph represents the greatest integer function, the answer is 2.

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

It is given that:

The graph of the greatest integer function is shown in the picture:

From the graph:

g(1) = 2

g(2) = 4

g(3) = 4

g(4) = 4

g(5) = 4

And so on

Thus, the value of g(1) is 2 because the graph represents the greatest integer function, the answer is 2.

Answer:

length = 14.14 m and width=width 11.32 m

Step-by-step explanation:

length be L and width be w

L:w = 5:4

L/w = 5/4

Let L =5k and w=4k

since A= lengthxwidth

A=5k x 4k

so, 160 = 20 k2

k 2 = 8

k = 2.828

since L = 5k in above, L= 5x2.828= 14.14

and since w=4k in above, w=4x2.828 = 11.32

This is my Guess. ..

Answer:

I hope it will help u

Step-by-step explanation:

As given that

L:W=5:4

L/W=5/4

hence we also know that

As given A=160m2

putt the value of A and L=(5/4)W in above equation ,

hence      160 = (5/4)W * W

W^2 = 160*4/5

W^2 = 32*4

W^2=128

taking square root

W= +_ 11.3

but length can't be negative so we take positive value of W

Answer:

$7.50

Step-by-step explanation:

Let the price of one sandwich = x

Hence,

The total cost = Cost of 5 identical sandwiches + 1 bag of chips

The bag of chips costs $1.25, and the entire order costs $38.75.

Hence:

$38.75 = 5x + $1.25

5x = $38.75 - $1.25

5x = $37.50

x = $37.50/5

x = $7.50

Therefore, the price of one sandwich is $7.50

Answer:

Step-by-step explanation:

rewrite 9-6x+[tex]x^{2}[/tex] as [tex]x^{2}[/tex]-6x+9.  (this step isn't necessary, but it's easier when the bigger term is in front)

There's two ways: using the quadratic formula, or just doing it in your head (for simple ones)

For the simple way:

think about what numbers not only multiply to equal c (represented by 9 in this case) but also add to equal -6 (represents b in this problem).  There are two numbers for this problem that work: -3 and -3.  So you would write the factored form as (x-3)(x-3)

Quadratic formula:

The formula is [tex]\frac{-b}{2a}[/tex] ±[tex]\frac{\sqrt{b^{2}-4ac } }{2a}[/tex]

This formula works for equations in the form of a[tex]x^{2}[/tex]+bx+c.

Substitute in the values to get:

[tex]\frac{6}{2} +\frac{\sqrt{-6^{2} -4(1)(9)} }{2}[/tex]

simplify:

3±[tex]\frac{\sqrt{36-36} }{2}[/tex]

3±[tex]\frac{0}{2}[/tex]

the answer is 3, which is the x-intercept.  Write that as (x-3)(x-3)

Answer:

The order is

Sherry >> Rachel>>Bobby

Step-by-step explanation:

Step one:

We want to find the smallest unit rate

given data

1. Bobby fills his bucket at a rate of 3/4 gallon in 2 minutes.

unit rate

=3/4/2

=3/4*1/2

=3/8

=0.375 gallons per minute

2. Rachel can fill her bucket at 1/5 gallon in 1/2 minute.

unit rate

=1/5/1/2

=1/5*2/1

=2/5

=0.4 gallons per minute

3.  Sherry can fill 3/8 gallon in 3/4 minute.

unit rate

=3/8/3/4

=3/8*4/3

=12/24

=0.5 gallons per minute

Answer:

588

Step-by-step explanation:

In a factor tree, I mostly like to look from down to up so that I can track down the non-square number. In a square number, there must be two factors that are exactly the same as each other, and when multiplied gives that square number.

So based on the 5 × 5, 2 × 2, and 7 × 7, we can tell that 25, 4 and 49 are all square numbers. We move up one level. Since the factors of 196 are square numbers, 196 is also a square number since it consists of 2² × 7².

We move another step up. 588 consists of 3 and 196. We know that 196 is a square number, but 3 is a prime number, which means that 3 only has a factor of 3 and itself. Thus, 588 is not a perfect square number since there should be a double factor for 3.
