Answer:

b: a over b divided by do over c

Step-by-step explanation:

You can solve this by plugging in numbers for each variable.

For example: a=1, b=4, c=1, d=2

1/4 ÷ 1/2 = 0.125

If you plug in the numbers for all the equations listed, only 1/4 ÷ 2/1 = 0.125.

One gallon of gasoline in Buffalo, New York costs $2.29. Across the border in Toronto, Canada, one liter of gallon costs $0.91.

AysviL [449]

Answer:

a) $ $3.46$

b) Cost of one gallon of gas is Toronto, Canada is higher by $ $1.17$

Step-by-step explanation:

Complete Question

One gallon of gasoline in Buffalo, New York costs $2.29. In Toronto, Canada, one liter of gasoline costs $0.91. There are 3.8 liters in one gallon.

a. How much does one gallon of gas cost in Toronto? Round your answer to the nearest cent.

b. Is the cost of gas greater in Buffalo or in Toronto? How much greater?

Solution

Given

Cost of one gallon of gasoline in Buffalo, New York $= 2.29$ dollars

Cost of one liter of gasoline in Toronto, Canada $= 0.91$ dollars

One gallon $= 3.8$ liters

Thus, $1$ liter $= \frac{1}{3.8}$ gallons

a) Cost of $\frac{1}{3.8}$ gallons of gasoline in Toronto, Canada $= 0.91$ dollars

Cost of $1$ gallons of gasoline in Toronto, Canada

$=3.8 * 0.91\\= 3.458\\= 3.46$

b) Difference in price for a gallon of gas for the two locations

$3.46 - 2.29 \\= 1.17$

Cost of one gallon of gas is Toronto, Canada is higher by $ $1.17$

What is the area, in square units, of the parallelogram shown below? A parallelogram ABCD is shown with height 7 units and base

Goshia [24]

Answer: The correct answer is: [B]:

____________________________________________

→ " 35 square units " .

____________________________________________

{or; write as: " 35 sq units " ; or; " 35 units² " .}.

____________________________________________

Step-by-step explanation:

____________________________________________

Note that the area, "A" ; of a "parallelogram" ;

→ {for which we wish to solve} ;

→ can be calculated by using the formula:

____________________________________________

→ " A = b * h " ;

→ { that is: " Area = base * height " } ;

→ in which:

____________________________________________

→ "A" is the "area" [of the parallelogram] ;

in: [ "square units" ; or: "sq units" ; or: "units² " ] ;

____________________________________________

→ "b" is the "base length" (of one of the bases of the parallelogram) ;

{Note that both bases of a parallelogram have equal lengths.

— Refer to "image attached" for additional information.}.

____________________________________________

→ "h" is the "perpendicular height" [of the parallelogram] ;

____________________________________________

Note:

All rectangles are parallelograms, but not all parallelograms are rectangles.

All squares are rectangles, but not all rectangles are squares.

____________________________________________

So, let us consider a "rectangle" that is not a square;

→ but has 4 (four) right angles; as follows:

____________________________________________

Rough sketch:

base (b)

---------------------------

| | height (h)

|_____________ |

____________________________________________

The formula (equation) for the area, "A" ; of a rectangle is:

→ " A = b * h " ;

→ { that is: " Area = base * height " .} .

→ Since a rectangle is a parallelogram;

→ The formula (equation) for the area, "A" ;

for Any parallelogram is the same :

→ " A = b * h " ;

→ { that is: " Area = base * height " .} .

____________________________________________

→ However, it is important to remember that the formula/equation for the "area, "A" ; for any parallelogram — [including All rectangles] — is actually:

→ " A = b * h " ; that is: " Area = base * [perpendicular] height " .

____________________________________________

Note that we are Not Given Any "image attached" that represents the: "parallelogram" —

Note: Refer to the text within "this very Brainly question being asked" ; that is; the following text:

____________________________________________

"the parallelogram ABCD" that is "shown below" {sic} ; as stated within the question.

____________________________________________

Nonetheless:

We are given:

h (height) = 7 units ; And:

b (base) = 5 units. ;

For our purposes, let us assume that the given "height, "h" = 7 units" ;

→ refers to the "perpendicular height " ;

Now, we can calculate the "Area; A" ; in "square units" ; as follows:

___________________________________________

→ " A = b * h " ; Solve for: "A" ;

Plug in our given values for "b" and "h" ; to solve for "A" ;

→ " A = (5 units) * (7 units) " ;

= 5 * 7 * units * units " ;

" A = 35 units² ;

or: " 35 square units " ;

→ which is:

___________________________________________

Answer choice: [B]: " 35 square units " .

___________________________________________

Note: Refer to "image attached" ; to refer to: "perpendicular height " — as regards to many "traditional" types of " parallelograms " .

___________________________________________

Hope this helps!

Best wishes to you in your academic pursuits

— and within the "Brainly" community, as well!
