Answer:

C

Step-by-step explanation:

Answer:

A whole number divided by a unit fraction is the same as multiplying a whole number by the inverse of the unit fraction.

Step-by-step explanation:

Given

[tex]8 \div \frac{1}{5} = 40[/tex]

[tex]8 * 5 = 40[/tex]

Required

Explain why both expressions are correct

No dropdown to select from. So, I will provide a general solution.

When a number is divided by a fraction.

Take for instance:

[tex]8 \div \frac{1}{5}[/tex]

The above can be expressed as the product of the number and the inverse of the fraction.

The inverse of 1/5 is 5.

So, we have:

[tex]8 \div \frac{1}{5} = 8 * 5[/tex]

The result of the above expression is:

[tex]8 \div \frac{1}{5} = 8 * 5 = 40[/tex]

What is factoring?

Factoring is finding what to multiply to find an expression. It is like splitting expression into a multiplication of simplified expression.

Why is it useful to try to factor out the GCF first when factoring?

Greatest common factor or GCF of two numbers is the largest number that divides evenly in both numbers, GCF works the same in polynomials, which divide the expression evenly .

Explain the relationship between factoring and multiplying polynomials. Give an example to help explain

Factoring take away the multiplication, to factorize a polynomial it means take apart what  is multiplied. the best example is a²+b²+2ab ( multiplied)

factorize :(a+b)(a+b)   take apart what is multiplied

Factor x^2-25, 3x^2-12x-15, and x^3+2x^2+3x+6

x²-25  =(x+5)(x-5)

3x²-12x-15 = 3(x²-4x-5)  GCF=3

3(x-5)(x+1)

x³+2x²+3x+6  (x+2) common factor

(x+2)(x²+3)

What are the key features needed to graph a polynomial function?

the key features are the vertex, axis of symmetry, x and y intercept

Explain how to find these key features to sketch a rough graph of a polynomial function

parabola : y=ax²+bx+c

ex: 3x²-12x-15

find vertex (h,k)

h=-b/2a =-(-12)/2(3)=2

k=f(h)=f(2)=3(2)²-12(2)-15

k=12-24-15=-27

vertex=(2,-27)

x intercept is when the graph =0 (y=0)

y intercept when x=0 then y= the constant c and where the graph cross the y axis

axis of symmetry is the x of the vertex: is a line about which a parabola is symmetrical and vertical when the axis of symmetric is vertical.

Why would someone want to factor a polynomial? Provide real world examples of different questions we can answer or facts we can determine from factoring a polynomial.

factor a polynomial helps us understand more about equations,factoring helps us rewrite the polynomial into simpler expression.

example from real life:

A homeowner has a back yard and wants to turn it to garden beds so he can plant his vegetables, he wants to fill it with dirt he needs 240 cubic feet to fill it  the length is 4 feet than the width , and the height is 4

solve:

length=W+4

height=1/3 w

V=length* width* height

240=(w+4)(w)(4)

351= 4w²+16w

4w²+16w-240=0

take 4 as common factor

4(w²+4w-60)

now factorize:

4(w-6)(w+10)=0

Answer:

~300 times

this is because each turn you have a one out of six chance, simply divide 1800 by 6 and voila there's your answer

Answer:

300 times.

Step-by-step explanation:

Looking at this, we have a 6-space spinner. Each number has a 1/6 chance of being landed on. As a result, all we really need to do is divide 1800 by 6 to get 300 times to get a 2, theoretically.

Answer:

challenge because it said 28 people spent between 15 and an hour if that is so the could have been there for an hour so there

Step-by-step explanation:

Answer:

The inference makes an incorrect statement.

Step-by-step explanation:

It is said that Tonya sampled 35 customers, where 28 of them spent 15-60 minutes, and 5 people spent over 60 minutes. This means that there are already 5 people that shop for over an hour. There may also be a bigger portion of shoppers that shop for exactly 60 minutes (1 hour), which is NOT less than 1 hour.

Hope that this helps! :)

Answer: D

Step-by-step explanation:

The sum of the interior angles of a quadrilateral is 360°.

55+55+125+125=360

Answer:

D. 55, 55, 125, 125

Step-by-step explanation:

To solve this problem we first need to know what the total degrees of a 4 angle quadrilateral is. The answer to this is 360°. Knowing this, we need to figure out which combination of numbers adds up to 360. To do this, I go through the list and check all of the options.

A.) 10+10+125+125=270

B.) 15+15+25+125=180

C.) 15+15+115+125=270

D.) 55+55+125+125=360

The formula relations given by Pythagorean theorem is used to

determine the lengths and area of the given squares and triangles.

Responses:

1. Area of a is H: 25

2. Length of b is I: 5

3. Length of C is A: 7.94

4. Area of d is B: 35.73

1. Given;

The area of the side squares are; 9 m² and 16 m²

According to Pythagorean theorem, we have;

Area of square a = 9 m² + 16 m² = 25 m²

2. b² = Area of side square a

Therefore;

b = √(25 m²) = 5 m

3. Given;

Area of the squares adjacent to the hypotenuse side and a leg are;

144 m² and 81 m² respectively

According to Pythagorean theorem, we have;

C² = 144 m² - 81 m² = 63 m²

C = √(63 m²) = √(9 × 7 m²) =  3·√7 m ≈ 7.94 m

4. Area of triangle d = [tex]\frac{1}{2}[/tex] × √(81 m²) × 7.94 m ≈ 35.73 m
