Brittany uses the ski machine and the treadmill at the gym for an exercise program. Her trainer wants her on an exercise program that meets these two conditions:
1) Brittany will exercise for at least 45 minutes and at most 1 hour and 15 minutes,
dividing her time between the ski machine and the treadmill.
2) Brittany will spend at least three times as much time on the treadmill as on the
ski machine.
a. Let x represent the time on the ski machine and y represent the time on the
treadmill. Write a system of inequalities that models the relationships between the
amounts of time Brittany spends on the two machines. You will have three
inequalities.

Answer:
Required inequalities are as following.
Brittany will exercise for at least 45 minutes:
x + y ≥ 45Brittany will exercise at most 1 hour and 15 minutes (= 75 min):
x + y ≤ 75Brittany will spend at least three times as much time on the treadmill as on the ski machine:

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

Solve each equation by completing the square. Write both answers separately.
Answers
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

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).

To the nearest tenth, what is the length of QR
Answers
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
