how to factorise the difference of perfect squares. for the g on the top and j on the top
Answer:
see explanation
Step-by-step explanation:
A difference of two squares is factored as
a² - b² = (a - b)(a + b)
(g)
1 - 81y²
= 1² - (9y)²
= (1 - 9y)(1 + 9y)
(j)

= (8x)² - (5y)²
= (8x - 5y)(8x + 5y)

Molly bought a large basket of 6060 apples. When she got home, she found 44 rotten ones. If she goes back and buys 200200 more apples, how many rotten apples would she expect there to be?
Answer: 13
Step-by-step explanation:
This is the correct question:
Molly bought a large basket of 60 apples. When she got home, she found 4 rotten ones. If she goes back and buys 200 more apples, how many rotten apples would she expect there to be?
From 60 apples, there are 4 rotten apples. This gives a fraction of:
= 4/60
= 0.06667
Therefore, when she buys 200 apples, tge number of rotten ones expected will be:
= 0.06667 × 200
= 13.334
= 13 approximately
A red marble is selected at random from a bag containing 2 blues and 9 red marbles and is not replaced.the probability that a second marble selected will also be red is
Answer:
So the probability of drawing a second red marble is 8 out 10 or 0.8.
Step-by-step explanation:
It seems to me that if one red marble is already gone, there are 8 red marbles left out of a total of 10 marbles.
So the probability of drawing a second red marble is 8 out 10 or 0.8.
Answer:
8/10 or 4/5 or 0.8
Step-by-step explanation:
since one red marble is already taken, there are only eight remaining now and the total number of marbles are ten now. So you have to divide.
Therefore, the probability is 8/10 or 4/5 or 0.8.
Solve for X in the following proportion: 6/33 = 24/x
Answer:
132
Step-by-step explanation:
We are given the equation 6/33 = 24/x. We would like to solve for x.
To get rid of the fractions, let's multiply both sides by 33x:
(6/33) * 33x = (24/x) * 33x
6x = 24 * 33 = 792
Divide by 6 from both sides:
x = 792/6 = 132
Thus, x = 132.

Point 6 is on line segment FH. Given FG=8 and GH=11, determine length FH
Answer:
GH = 20
Step-by-step explanation:
We have that
FH = FG + GH ← substitute values
4x + 8 = x + 5x
4x + 8 = 6x ( subtract 4x from both sides )
8 = 2x ( divide both sides by 2 )
4 = x
Hence GH = 5x = 5 × 4 = 20GH = 20

Carol got $500 for her birthday. She wants to buy some video games and a gaming system. An Xbox 1 costs $278. A new game costs $62. What is the most amount of games Carol can afford?
Answer:
She can buy 3 games.
Step-by-step explanation:
Giving the following information:
Carol got $500 for her birthday.
Xbox 1= $278
A new game costs $62
First, we need to structure the total cost formula:
Total cost= 278 + 62x
x= number of games
Now, we can isolate x:
500= 278 + 62x
222/62= x
3.58=x
She can buy 3 games.

Alexander was given a gift card for a coffee shop. Each morning, Alexander uses the card to buy one cup of coffee. Each cup of coffee costs $1.50 and after buying 4 cups of coffee, the card had a $9 remaining balance. Write an equation for A,A, in terms of x,x, representing the amount money remaining on the card after buying xx cups of coffee.
Answer: [tex]A = 15 - 4x[/tex] .
Step-by-step explanation:
Total amount remaining = Initial amount in the card-( Cost per cup × (Number of cups) )
Each cup of coffee costs $1.50 and after buying 4 cups of coffee, the card had a $9 remaining balance.
i.e. 9 = Initial amount in card - (1.50 × 4)
⇒ 9 = Initial amount in card - (6)
⇒ Initial amount in card = 9+-6 =15
⇒ Initial amount in card = $15
Let A be the amount money remaining on the card after buying x cups of coffee.
So, A = 15 - 4x
Hence, the required equation is [tex]A = 15 - 4x[/tex] .
Answer:
A= -1.50x+15

The sum of an arithmeit cprogression consisting of 20 positive integer terms with positive common difference is equal to 2020. (a) how many progressions are possible (b) what are the smallest and largest possble values of the first term?
Answer:
a) possible progressions are 5
b) the smallest and largest possible values of the first term are 16 and 82
Step-by-step explanation:
Sum of terms:
Sₙ = n/2(a₁ + aₙ) = n/2(2a₁ + (n-1)d)S₂₀ = 20/2(2a₁ + 19d) = 10(2a₁ + 19d)2020 = 10(2a₁ + 19d)202 = 2a₁ + 19dIn order a₁ to be an integer, d must be even number, so d = 2k
202 = 2a₁ + 38k101 = a₁ + 19kPossible values of k= 1,2,3,4,5
k = 1 ⇒ a₁ = 101 - 19 = 82k = 2 ⇒ a₁ = 101 - 38 = 63k = 3 ⇒ a₁ = 101 - 57 = 44k = 4 ⇒ a₁ = 101 - 76 = 25k = 5 ⇒ a₁ = 101 - 95 = 16As per above,
a) possible progressions are 5b) the smallest and largest possible values of the first term are 16 and 82Answer:

Air passes from the trachea to the
bronchi,
Oxygen enters tilblood cells.
Air enters the nostrils.
Air diffuses from the alveoli to the blood
cells.
Blood transports oxygen to other cells.
Answer:
Step-by-step explanation:1. Air enters the nostrils: The human nose has two openings, which are called as nostrils. The air from the surrounding atmosphere enters the human body firstly, through nostrils and than enters inside the nasal cavity.
2. Air passes from the trachea to the bronchi: The air through nasal cavity passes towards pharynx to larynx, then to trachea and the air enters into the lungs inside the branching network of small tubes called as bronchi.
3. Air diffuses from the alveoli to the blood cells: The brochial tubes are further, branched into small alveoli. At alveoli the exchange of oxygen and carbon dioxide containing blood takes place.
4.Oxygen enters the blood cells: The oxygen carrying blood passes from the alveoli into the capillaries, whereas carbon dioxide passes from the capillaries into the alveoli.
5. Blood transports oxygen to other cell: The blood flows from the lungs transports oxygen to all the cells of the body.
Answer:
1. Air enters the nostrils
2. Air passes from the trachea to the bronchi
3. Air diffuses from the alveoli to the blood cells
4.Oxygen enters the blood cells
5. Blood transports oxygen to other cell

The perimeter of the circle with an area of 32 π square units is 2√32π units.
Given,
The area of a circle is 32 π square units.
We need to find its perimeter.
What is the area of a circle?The area of a circle is given by:
= π r²
The perimeter of a circle is given by:
= 2πr
Where r = radius
Find the area of a circle.
Area = π r²
32 π = π r²
Divide both sides by π
32 = r²
r = ±√32
r can not be negative so we have,
r = √32
Find the perimeter of a circle.
P = 2πr
P = 2 x π x √32
P = 2√32 π units
The perimeter of the circle with an area of 32 π square units is 2√32π units.
