What is the "Zero Product Property"?
Provide an example please!!
Answer:
The Zero Product Property basically means that is ab=0 , then either a=0 or b=0. (Or even both). A product of factors is zero if and only if one or more of the factors is zero.
Example: (2x-1 ) (x +4) = 0

in a class of 60 student, the number of student who passed biology is 6 more than the number who passed chemistry every student passed both at least one of the two subjects and 8 student passed both subject
Firstly we need to find how many students passed chemistry or biology
60-8=52 studdnts passed biology or chemistry
Let number of students who passed chemistry is x, than number of students who passed biology is 52-x.
[tex]52 - x - x = 6 \\ - 2x = - 46 \\ x = 23[/tex]
So, 23 students passed chemistry, than

If he sets the base of the ladder 6 feet away from his home, what is the minimum length that the ladder can be? Explain how you solved this question using context and at least three sentences. Hint: Draw your the scenario and label given values.
Answer:
10 feet
Step-by-step explanation:
It becomes a right-angled triangle with height of 8feet and base of 6feet.
Using Pythagoras theorem:
a² = b² + c²
a² = 8² + 6²
a² = 64 + 36

Find the 12th term of the geometric sequence 8, 16, 32, ...
Answer:
Step-by-step explanation:
\[a_{n}=a{1}r^{n-1}\]
r=16/8=2
a_{12}=8(2)^{12-1}
[tex]a_{12}=8(2)^{11}=16384[/tex]
The 12th term of the geometric sequence is 16384.
What are arithmetic and geometric sequence?An arithmetic sequence is a set of numbers in which every no. next to the previous number has the same common difference
d = aₙ - aₙ₋₁ = aₙ₋₁ - aₙ ₋₂.
In a geometric sequence numbers are written in the same common ratio(r).
It means every next number is a multiple of a common constant and the previous number.
r = aₙ/aₙ₋₁ = aₙ-₁/aₙ₋₂.
Given, a geometric sequence 8, 16, 32,... which has a common ratio(r)
= 16/8 and first term a₁ = 8.
We know nth term of a geometric sequence is aₙ = a₁rⁿ⁻¹.
∴ 12t term of the geometric sequence is a₁₂ = 8.2¹²⁻¹
= 8.2¹¹.
= 8.2048.
= 16384.

The sea turtle habitat at the zoo is made by connecting two large aquariums. The first aquarium is 6 m long, 4 m wide, and 2 m high The second aquarium is 8 m long 9 m wide and 3 m high how many cubic meters of space do the sea turtles have in their habitat
Answer:
264 cubic metres
Step-by-step explanation:
We need to find the volume of both aquariums and add them up.
The aquariums are shaped as rectangular prisms.
The volume of a rectangular prism is:
V = L * W * H
where L = length, W = width, H = height
The first aquarium is 6 m long, 4 m wide, and 2 m high. Its volume is:
V = 6 * 4 * 2 = 48 cubic metres
The second aquarium is 8 m long, 9 m wide and 3 m high. Its volume is:
V = 8 * 9 * 3 = 216 cubic metres
The amount of space the turtles have is therefore:
V = 48 + 216 = 264 cubic metres

A new phone costs $450. There is a 40% discount on the price of the phone and an 8% sales tax on the discount price. What is the final cost of the phone after the discount and the sales tax?
Answer:
291.60 is the final cost
Step-by-step explanation:
First find the cost of the phone before tax
Discount
450*.40
180
Price after discount
450-180
270
Now find the tax
270* 8%
270 *.08
21.60
Add this to the price after discount
270+21.60
291.60
Answer:
291.60
Step-by-step explanation:
40% of 450 is 270 and 8% of 270 is 21.6 so add 21.6 to 270 and you get 291.60

Simplify your answer and write it as a fraction or whole number.
Answer: 1/9
Step-by-step explanation:
You have 3 possible options. The probablility of the spinner landing on 3 is 1/3. The probability of it landing on 2 is also 1/3. For them to happen together, you multiply them. 1/3 * 1/3 = 1/9.
The probability of landing on a 3 and then landing on a 2 is,
⇒ 1/9
What is mean by Probability?The term probability refers to the likelihood of an event occurring. Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one

An equilateral triangle has a side length of 7 cm. If a perpendicular is dropped from a corner, what is the length of the perpendicular?
Answer:
6.06cm
Step-by-step explanation:
An equilateral triangle is a triangle that has all its sides equal. If the given equilateral triangle has a side length of 7 cm, then all its sides are 7cm each. To get the length of the perpendicular dropped from a corner. we will use the Pythagoras theorem.
According to the theorem,
hyp² = opp²+adj²
Lets take the height as the opposite side of one of the right angled triangle as shown in the attachment.
hyp = 7cm and adj = 7/2 = 3.5cm
opp² = 7² - 3.5²
opp² = 49 - 12.25
Opp = √36.75
Opp = 6.06cm
This shows that the length of the perpendicular is 6.06m
The garden has an area of 28 square meters. The length of the garden is 7 meters. What is the width of the garden?
You have to find the width
Answer:
The answer is 4
Step-by-step explanation:
Since the total area is 28, and the length is 7. Therefore 28 divided by 7 equals 4.
Hope this helps
Answer:
4 meters
Step-by-step explanation:
Let's assume this is a rectangular garden.
The area of a rectangle can be found using:
a=l*w
We know the area is 28 square meters and the length is 7 meters. We can substitute 28 in for a, and 7 in for l.
28=7*w
Now we need to solve for w. To solve, we have to get w by itself. 7 and w are being multiplied. To reverse this, divide both sides by 7.
28/7=7*w/7
28/7=w
4=w
The width is 4 meters

Step-by-step explanation:
1/5×80=80/5=16 because 1/5 out of 80 means to multiply 1/5 by 8o so the answer to that question is 16.
48÷1/2=48×2/1=96/1=96 because when you divide a fraction by fraction or a fraction with a number there is a rule that says you have to reverse the fraction on the right side and replace the division sign to a multiply sign and multiply. so the answer becomes 482)×2/1 which equals 96.
