Complete question :

One gallon of gasoline in buffalo, New York costs $2.29. In Toronto, Canada, one liter of gas costs $0.91. There are 3.8 liters in one gallon. How much does one gallon of gas cost in Toronto?

Answer:

$3.458

Step-by-step explanation:

Given that :

Cost per gallon in Buffalo, New York = $2.29

Cost per Litre in Toronto, Canada = $0.91

Number of litres in 1 gallon = 3.8

The cost per gallon in Toronto, Canada will be :

3.8 * cost of a Litre

3.8 * $0.91 = $3.458

Hence, cost of a gallon in Toronto, Canada = $2.73

Answer:

F(x) represents the zeros of the given quadratic function. i.e. the linear factors represents zero when we resolve the expression

Step-by-step explanation:

Describing the relationship between the zeros of the quadratic function and the linear factors of the expression using an example as shown below

lets describe this using the example below :

quadratic expression  : F(x) = ax^2 + bx + c

let the linear factors of  F( x ) = 0

F(x) represents the zeros of the given quadratic function above i.e. the linear factors represents zero when we resolve the expression

Answer:

u ≤ 2

Step-by-step explanation:

Given

- 10 ≤ - 5u

Divide both sides by - 5 , reversing the symbol as a result of dividing by a negative quantity.

2 ≥ u , then

u ≤ 2

Answer:

75.4 meters³

Step-by-step explanation:

182=288 so 74 76 78 80 82 ×2 == 76 78 80 82 84 ans the range is 2920

First you have to change "-2x+6y-9=0" into slope intercept form (y=mx+b).

Add the -9 to 0, to get (-2x+6y=9).

Now add -2x to the 9, to get (6y= -2x+9). Since -2x and 9 aren't like terms.

Divide 6 on both sides to get (y=-2/6x+9).

Plot this on a graph as shown above. (16.5, 3.5)

Answer is: D) 3.35, since it's closer.

Answer:

37) ±√29 - 4

Completing the square utilizes this formula [tex](\frac{b}{2})^{2}[/tex]. We know that b=8, 8 can be plugged into this formula to get [tex](\frac{8}{2})^2[/tex]. Simplify to get 16. Now, we can add this into the equation to get [tex]k^{2}+8k+13=26[/tex]. Subtract 26 to both sides, so the equation can equal to 0. [tex]k^{2} +8k-13=0[/tex] would be the resulting equation. Now, let's use quadratic formula to find the solution. The quadratic formula is (-b+-√b^2-4ac) / 2a. Plug in all of our values to get (-8+-√8^2-4(1)(-13)/2(1). Simplify the equation to get ±√29 - 4.

38) ±√21 - 2

Let's use the same formula. b=4, so [tex](\frac{4}{2} )^2[/tex]. Simplify to get 4. Add that into the equation to get [tex]x^{2}+4x-5=12[/tex]. Subtract 8 on both sides, so the equation can equal to 0. [tex]x^{2}+4x-17=0[/tex] would be the result. Use the quadratic formula again to find the solution. Plug in all of the values to get ±√21 - 2

Answer:

D

Step-by-step explanation:

the answer is d because it's the 3 and 5/8ths per pie this it is multiplied by x.

Answer:

x=6 degrees

Step-by-step explanation:

I know that 31+(10x-1)=90. Then I have to subtract 31 from 90 to get 10x -1.

That's 59. I solve for x in the equation 59=10x-1.

That is the same thing as 60=10x, which is also the same as 6=x.

Answer:

|QR| = 17.6

Step-by-step explanation:

To answer this we need to show that the triangles are similar or to assume that they are similar.

Note the following:

1.  The ratio of the longest sides is 12.5 to 25.0, or 1/2;

2.  The ratio of the shortest sides is 5.2 to 10.4, or 1/2

Therefore the ratio of the longer legs is 8.8 to QR, also equal to 1/2

 8.8        1

-------- = -----

  QR       2

Cross-multiplying, we get |QR| = 17.6

Answer:

[tex] \displaystyle B )\overline{ \text{QR }}= 17.6 cm[/tex]

Step-by-step explanation:

we have two similar triangles

we want to figure out the measure of QR

remember that,

the ratio of the corresponding sides of two similar triangles is equal

thus,

[tex] \displaystyle \frac{8 .8}{QR} = \frac{5.2}{10.4} [/tex]

cross multiplication:

[tex] \displaystyle5.2 QR = 91.52[/tex]

divide both sides by 5.2:

[tex] \displaystyle \frac{5.2 QR }{5.2}= \frac{ 9 1.52}{5.2}[/tex]

simplify division:

[tex] \displaystyle QR = 17.6 cm[/tex]

hence, our answer is B

Step-by-step explanation:

The volume of the cylinder is

[tex]V=(\pi)(2^{2})(3)=12\pi[/tex]

If we let the height of the cone h, the volume of the cone is

[tex]V=\frac{1}{3}(\pi)(3^{2})(h)=3\pi h[/tex]

Setting these volumes equal,

[tex]12\pi=3\pi h\\\\12=3h\\\\h=\boxed{4 \text{ in}}[/tex]
