If a car travels 340 miles on 20 gallons of gas how far can it travel on 25 gallons of gas

Answers

First, divide 340 miles by 20 gallons of gas, to see how many miles you have per gallon. 340 divided by 20 = 17 mpg. Next you multiply 17 mpg by 25 gallons of gas to see how many miles you can go.
17 times 25 = 425 miles. Your answer is 425 miles.

7) The line plot below shows the weight(in tons) of boxes on pallets.
X
X X X
_________________
1/4 2/4 3/4 4/4

Each x = 1 Pallet
If the weight were redistributed evenly,
how much weight would be on each
pallet?

Answers

Answer:

Each pallet will have 7/16 tons of weight

Step-by-step explanation:

Calculate total weight: 2×1/4 + 2/4 + 3/4

= 7/4 tons

total number of boxes= 4

so to divide the weigth evenly among all pallets: (7/4)÷ 4

= 7/16 tons

( x − 3 )^2 as trinomial in standard form

Answers

Given (x - 3)^2, its trinomial in standard form, y = ax^2 + bx + c:

You must expand the binomial through FOIL method:

(x - 3)^2
x ^2 - 3x - 3x + 9

Combine like terms:

y = x^2 - 6x + 9
where a = 1, b = -6, and c = 9.
