Answer:

c) 282.5 ft²

Step-by-step explanation:

Formula we use,

A = L × W

The area of one floor will be,

→ 12 1/2 × 10

→ 25/2 × 10

→ 250/2

→ 125 ft²

The area of another floor will be,

→ 15 3/4 × 10

→ 63/4 × 10

→ 630/4

→ 157.5 ft²

Total area of the new carpet is,

→ 125 + 157.5

→ 282.5 ft²

Hence, the total area is 282.5 ft².

If One floor is 12 1/2 feet long, and the other floor is 15 3/4 feet long. Each floor has a width of 10 feet. Then total area of new carpet is 282.5 ft²

The area of Rectangle is length times of width.

Given that new carpet put on the rectangular floors of two rooms in his house.

One floor is 12 1/2 feet long

Second floor is 15 3/4 feet long.

Width is given by 10 feet.

We know that area of rectangle is

Area = Length × Width

The area of one floor will be,

12 1/2 × 10

25/2 × 10

250/2

125 ft²

The area of another floor will be,

15 3/4 × 10

63/4 × 10

630/4

157.5 ft²

Total area of the new carpet is,

125 + 157.5

282.5 ft²

Hence, the total area of new carpet is 282.5 ft².

The  the required value of function of the expression when x equal to 5 i.e f(5) is 167.

A function is defined as a relation between a set of inputs having one output each. function is a relationship between inputs where each input is related to exactly one output. Every function has a domain and codomain or range. A function is generally denoted by f(x) where x is the input.

Given:

The given expression is

f(x) =[tex]7x^{2} -8[/tex]

We have to find the value of f(5).

According to given question we have

f(x) =[tex]7x^{2} -8[/tex]

Put the value of x= 5  in the given function  we get,

f(x) =[tex]7x^{2} -8[/tex]

f(5) =[tex]7(5)^{2} -8[/tex]

After simplifying we get

f(5)=167

Answer:

It's the graph with two dots and no area marked, first image (for me).

Step-by-step explanation:

|x| = 1 means "the distance from x to the 0 point on the axis is exactly 1". There's only 2 numbers x that satisfy that condition: -1 and 1

The second and third image both show an area marked, so it cannot be the right answer, while the first image shows precisely two numbers: -1 and 1

Perimeter of rectangle is  9.5 inches

If the length of the rectangle is l and its width is w,

l = 4w + 1, and

lw = (4w+1)×w = 3.

This yields 4w² + 1w -3= 0, which can be solved in the normal way for quadratic equations.

Solving the equation we get as

w=0.75 or w=-1

as it an not be negative value hence w=0.75

l=4

The mass of water will change its temperature is 44.09 g.

Given that the temperature is change by 3.0°C when 635 J of heat is added to it.

Based on the given information, we know the following variables:

ΔT=3°C

Q=635J

C=(4.8 J)/(g×°C)

Here, we want to do is rearrange the equation to solve for m and this can be done by dividing both sides by C and ΔT to get m by itself like this:

m=Q/(ΔT×C)

Now, we want to substitute all the given values in the above formula, we get

m=635J/(3°C×(4.8J/(g×°C)))

m=635J/(14.4J/g)

m=44.09g.

Hence, the mass of water will change its temperature by 3.0 °C when 635 J of heat is added to it 44.09g.

Answer:

x = 2, y = -1

Step-by-step explanation:

Now change the equation,

→ x + y = 1

→ y = 1 - x

Then the value of x will be,

→ 2x + y = 3

→ 2x + 1 - x = 3

→ x = 3 - 1

→ [ x = 2 ]

Therefore, the value of x is 2.

Now value of y will be,

→ y = 1 - x

→ y = 1 - 2

→ [ y = -1 ]

Hence, the value of y is -1.

n^2-1

20th term is then 399

Step-by-step explanation:

The rule behind the sequence could be anything, but it is very likely that we're supposed to notice that the terms are all squares minus 1

0 = 1*1 - 1

3 = 2*2 - 1

8 = 3*3 - 1

15 = 4*4 - 1

24 = 5*5 - 1

So we expect that the explicit formula is n^2-1 and the 20th term is 399

r = number of reptiles on the endangered species list

2r = twice that number

2r < 127 since the 127 is more than twice the number of reptiles

Solve for r by dividing both sides by 2

2r < 127

r < 127/2

r < 63.5

If r is a positive whole number, then r could be anything from this set: {1, 2, 3, ..., 62, 63}

Unfortunately there isn't enough information to fully pin down what r is.

He can make 2 meat balls from the remaining turkey.

Total pounds of ground turkey available = 3 pounds.

Turkey used to make 6 meat ball = 3 / 8 of 3 pounds = 9 / 8 pounds

Turkey used to make 1 meat ball = 9 / 8 ÷ 6 = 3 / 16

1 / 8 meat = 1/ 8 of 3 = 3 / 8 pound of meat.

Number of meatballs made = 3 / 8 × 16 / 3 = 2

The correct option is A. {(–4, 3), (–2, 7), (–1, 0), (4, –3), (11, –7)}.

The function which also has an inverse that is also a function is {(–4, 3), (–2, 7), (–1, 0), (4, –3), (11, –7)}.

An inverse in mathematics is a function which serves to "undo" another function. That is, if f(x) yields y, then placing y into the inverse of f yields x.

In response to the given question

We understand that such a function is really only one that has a unique y value that corresponds to x.

An inverse function is only a function is if function being inversed is also a function.

Thus, option (A) has all x corresponding to y values that are different, but all remaining options have the values repeating, so that will not be a function because only (A) has to inverse.

Answer:

12, 3/5, 25%, -1/12, -0.17

Step-by-step explanation:

The simplest way to do this is to convert all of the numbers into either a fraction, decimal, or a percentage. In my opinion, it is easier to use a percentage here.

25% is already a percentage

-0.17 = -17%

3/5 = 60%

-1/12 (you can use a calculator to divide and find the percentage here) = -8.33

12 = 1200%

Now that the rational numbers are all in the same unit, it is easier to sort them. In the end, we get this list (from greatest to least):

12, 3/5, 25%, -1/12, -0.17

FINAL ANSWER: 12, 3/5, 25%, -1/12, -0.17

Answer:Yes 90.2 x 10-8 is greater then 90.2 x 10-6

Step-by-step explanation:

The polynomial equation is (x³ - 7x² + 20x - 24) = 0 and the Error that made by Andrew is incorrect factors of the roots.

Polynomial Equation:

The equations formed with variables, exponents and coefficients are called as polynomial equations.

Roots of the Polynomial:

Roots of a polynomial refer to the values of a variable for which the given polynomial is equal to zero.

Given,

Roots of the polynomial are: 3, 2 + 2i, 2 - 2i.

Here we need to find the error he made and the correct form of the equation.

According to the factor theorem, if a is a root of the polynomial P(x), then (x - a) is  a factor of P(x).

According to this definition:

=> (x - 3) , (x - (2 + 2i)) , (x - (2 - 2i))

are factors of the required polynomial.

Simplifying the brackets, we get:

=> (x - 3), (x - 2 - 2i), (x - 2 + 2i)

are factors of the required polynomial.

This is the step where Andrew made the error.

The factors will always be of the form (x - a) , not (x + a).

Andrew wrote the complex factors in form of (x + a)  which resulted in the wrong answer.

So, the polynomial would be:

=> (x - 3)(x - 2 - 2i)(x - 2 + 2i) = 0

=> (x - 3) (x² - 2x + 2xi - 2x + 4 - 4i - 2xi - 4i - 4i²) = 0

When we simplify it, then we get,

=> (x - 3)(x² - 4x + 4 + 4) = 0

=> (x - 3)(x² - 4x + 8) = 0

=> (x³ - 4x² + 8x - 3x² + 12x - 24) =0

=> (x³ - 7x² + 20x - 24) = 0.
