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.

Answer:
x = ±i[tex]\sqrt{2}[/tex], x = ±i
Step-by-step explanation:
x^4 + 3x^2 + 2 = 0
x^4 + x^2 + 2x^2 + 2 = 0
x^2 ( x^2 + 1 ) + 2 ( x^2 + 1 ) = 0

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.

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

Total Employees = 50
Part-Time Employees = 35
Formula:
Percentage of Part-Time Employees =
(Part-Time Employees/Total Employees) x 100
=(35 / 50) x 100
=(0.7) x 100
= 70

Answer:
n = -3
Step-by-step explanation:

Answer:
X Intercept: (-2, 0)
Y Intercept: (0, 7)
Explanation:
Plug y = 0 into the equation and solve the resulting equation 7x = −14 for x. Plug x = 0 into the equation and solve the resulting equation −2y = −14 for y.
Answer:
(- 2, 0 ) and (0, 7 )
Step-by-step explanation:
To find the x- intercept let y = 0 in the equation and solve for x
7x - 2(0) = - 14, that is
7x = - 14 ( divide both sides by 7 )
x = - 2 ⇒ (- 2, 0 ) is the x- intercept
To find the y- intercept let x = 0 in the equation and solve for y
7(0) - 2y = - 14, that is
- 2y = - 14 ( divide both sides by - 2 )
y = 7 ⇒ (0, 7 ) is the y- intercept
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
