Trish is sorting bolts for her home repair business. She has an 8-pound bag of bolts. If each kitchen her team repairs requires 1/5 pound of bolts, how many kitchen can she repair? Joshua solves the problem by finding 8÷1/5=40. Melanie solves the problem by finding 8×5=40
. Use the drop-down menus to explain why Joshua and Melanie are both correct.
a whole number by a unit fraction is the same as multiplying a whole number by the of the unit fraction.
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? Why is it useful to try to factor out the GCF first when factoring?
Explain the relationship between factoring and multiplying polynomials. Give an example to help explain.
Factor x^2-25, 3x^2-12x-15, and x^3+2x^2+3x+6 .
What are the key features needed to graph a polynomial function? Explain how to find these key features to sketch a rough graph of a polynomial function.
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.
Answer:
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

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.

Did any get the answer for puzzle 3 in Pythagorean Theorem Digital Escape!
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
Where can the Pythagorean theorem be used to find the lengths and areas of a figure?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
Area of a is H: 252. b² = Area of side square a
Therefore;
b = √(25 m²) = 5 m
Length of b is I: 53. 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
Length of C is A: 7.944. Area of triangle d = [tex]\frac{1}{2}[/tex] × √(81 m²) × 7.94 m ≈ 35.73 m
Area of d is B: 35.73Learn more about Pythagorean theorem here:

B. 15°, 15°, 25°, 125°
C. 15°, 15°, 115, 125°
D. 55°, 55°, 125°, 125°
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

Tonya sampled 35 customers leaving the grocery store to find out how long they spend shopping. The results were that two people spent less than 15 minutes shopping, 28 people spent between 15 minutes and an hour shopping, and five people spent over an hour shopping.
Inference: Most customers spend less than an hour shopping.
Defend or challenge the inference with at least two complete sentences.
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.
