1. Natoy's rectangular swimming pool has the length of 3m more than thrice its
width. What are the dimensions of the pool if it has an area of 216m2?
Width (w)
Length (/) = 3w + 3
Answer:
Step-by-step explanation:
Given
Natoy's rectangular swimming pool has the length of 3m more than thrice its
width.
Width=w
Length =3w+3
So
Area of the rectangular swimming pool=length×width
216=(3w+3)×w
216=3w^2+3w
3w^2+3w-216=0
3(w^2+w-72)=0
W^2+w-72=0
W^2+(9-8)w-72=0
W^2+9w-8w-72=0
W(w+9)-8(w+9)=0
(W+9)(w-8)=0
Sotwo value of w are 8,-9
We take positive value for rectangular swimming so we take w=8m
Width=8m
Length=3×8+3
= 24+3
=27m

A van travels 180 miles on 12 gallons of gas. At that rate, how much gas will it need to travel 330 miles
Answer: 22 gallons of gas.
The amount of gas needed to travel 330 miles will be 36.67 gallons.
What are ratio and proportion?A ratio is a group of sequentially ordered numbers a and b expressed as a/b, where b is never equal to zero. When two objects are equal, a statement is said to be proportional.
The rate is the ratio of the amount of something to the unit.
For example - If the speed of the car is 20 km/h it means the car travels 20 km in one hour.
A van travels 180 miles on 12 gallons of gas. Then the rate is given as,
Rate = 20 / 180
Rate = 0.1111 gallons per mile
At that rate, the amount of gas needed to travel 330 miles will be given as,
⇒ 330 x 0.1111
⇒ 36.67 gallons
The amount of gas needed to travel 330 miles will be 36.67 gallons.
More about the ratio and the proportion link is given below.

Answer:
1. y = -2x + 5
2. y = 3/5x + 5
3. y = -4/5x - 4
4. y = - 1
5. yes
6. yes
7. yes
8. no
Step-by-step explanation:
1. (4,-3) parallel to y= -2x
-3 = -2(4)+b
b=5
2. (-5,2) parallel to y = 3/5x
2= 3/5(-5)+b
b=5
3. (-5,0) -4/5x
0 = -4/5(-5)+b
b = -4
4. (-4,-1)
y= -1
5. yes
6. yes
7. yes
8. no
Same slope = parallel ex. y = -5x +7, y = -5x +12opposite reciprocal = perpendicular ex. y = -5x +7, y = 1/5x + 12to find "b" with slope and point(x,y) y = mx + b
plug in the y value and x value in the eqaution and m=slope, solve for b
Write the recursive, arithmetic and explicit formula for the nth term of the sequence:
8, 1, -6, -13,... Then find the 10th term
Recursive Formula
[tex]\begin{cases}a_1 = 8\\a_n = a_{n-1}-7\end{cases}[/tex]
The top row says the first term is 8
The bottom row says that to get the nth term, we subtract 7 from the (n-1)th term. So basically we subtract 7 from each term to get the next term.
Note the subscripts tell us which term we're working with.
======================================================
Arithmetic Formula
We have a = 8 as the first term and d = -7 as the common difference.
a(n) = a + d(n-1)
a(n) = 8 + (-7)(n-1)
a(n) = 8 - 7n + 7
a(n) = -7n+15
The nth term arithmetic formula is a(n) = -7n+15
If you plug in n = 1, you should get a(n) = 8
If you plug in n = 2, you should get a(n) = 1
and so on.
=======================================================
Finding the 10th term
Plug in n = 10 to get
a(n) = -7n+15
a(10) = -7(10)+15
a(10) = -70+15
a(10) = -55
The 10th term is -55

Resolve into factors:- 9x4 + 2x²y²+ y4
Answer:
(3x^2+y^2+2xy)(3x^2+y^2-2xy)
Step-by-step explanation:
9x^4+2x^2y^2+y^4
(3x^2+y^2+2xy)(3x^2+y^2-2xy)
Both terms are perfect squares. So you will factor using the difference of squares formula. a^2-b^2=(a+b)(a-b)
Take what the square is for every term.
9x^4. What squared is 9? 3 and take half of the power or 2. That's how you get the 3x^2
2x^2y^2 is the same way. 2xy and 2xy
y^4 is y but dived he powers by 2 to get y^2.
Take one of each and but in () like I have above.

The ratio of pears to bananas in a fruit basket is 6 to 5. If there are 44 pears and bananas altogether, how many bananas must there be?
Answer:
20 BananasStep-by-step explanation:
we are going to apply the part to all method to solve this problem
Step one:
Given that the ratio of pears to banana is 6:5
the total ratio is 6+5= 11
and the total fruit is 44
Step two:
let the number of banana be x
applying the part to all method
5/11=x/44
cross multiply we have
11x=44*5
11x=220
divide both sides by 11
x=220/11
x=20
the bananas are 20 in numbers

What are arithmetic Operations?The four fundamental operations of arithmetic are addition, subtraction, multiplication, and division of two or even more items.
Included in them is the study of integers, especially the order of operations, which is important for all other areas of mathematics, notably algebra, data management, and geometry.
As per the data provided in the question,
The amount of floor required to make the recipe = 9/4 = 2.25 cups
But, Saron wants to make 3 1/2 times of recipe.
= 7/2 times or 3.5 times.
So, the amount of floor requried for this will be equal to,
3.5 × 2.25 = 7.87 cups of the floor.

Marc plans to create a model of the solar system for his school’s science fair. He knows the solar system includes many celestial bodies.
Which statement identifies a possible limitation of this model?
A. The model will be supported with scientific evidence.
B. The model will include all planets of the solar system.
C. The model will be used to predict planet distances and sizes.
D. The model will oversimplify what the solar system looks like.
Answer:
C) The model will be used to predict planet distances and sizes.
Step-by-step explanation:
A model is used to distort the size and shape of the observed object. Therefore, a model of the solar system will not be accurate when it comes to the planet's distances and sizes. It would take miles upon miles to accurately show the distance between planets.
