Step-by-step explanation:

675x1.07

1 would be 675. Since there is a 7 percent sales tax, it would be 107 percent of the cost.

Answer:

$722.25

Step-by-step explanation:

Answer:

since the rate is the same for both trains, and we know that the distance train A travels plus the distance train B travels equals 562.5 miles, we can use the D(istance) = R(ate) * T(ime) formula to solve this.

Train A:

da = R * 4

Train B:

db = R * 3.5 (using 3.5 instead of 3 and 1/2)

Solve for R:

R * 4 + R * 3.5 = 562.5

7.5 * R = 562.5

R = 75

The trains are traveling at 75 miles per hour.

Step-by-step explanation:

Answer:

speed = distance / time

since they are moving in opposite direction, the time is the sum of the two times = 2 1/2 + 4 = 6 1/2 = 13/2

speed = 585/(13/2) = 90 miles per hour.

Step-by-step explanation:

With the midpoint formula, we're basically finding the average of the two variables, x and y.

Formula: [tex](\frac{x_{1} + {x_2} }{2}, \frac{_{1} + {y_2} }{2} )[/tex]

[tex](\frac{{-1} + {3}}{2} , \frac{{-2} + {4}}{2} )[/tex]

[tex](\frac{2}{2}, \frac{2}{2})[/tex]

Answer:

[tex]10\ \text{sq. units}[/tex]

Step-by-step explanation:

The parabola's are

[tex]y=-x^2+9[/tex]

[tex]y=2x^2-3[/tex]

So

[tex]-x^2+9=2x^2-3\\\Rightarrow 12=3x^2\\\Rightarrow \\\Rightarrow x=\sqrt{\dfrac{12}{3}}\\\Rightarrow x=\pm 2[/tex]

[tex]y=-x^2+9=-(2)^2+9\\\Rightarrow y=5[/tex]

[tex]y=-(-2)^2+9=5[/tex]

So, the points at which the parabola's intersect each other is [tex](2,5)[/tex] and [tex](-2,5)[/tex]

The three points of the triangle are [tex](2,5)[/tex], [tex](-2,5)[/tex] and [tex](0,0)[/tex]

Area of a triangle is given by

[tex]A=\dfrac{1}{2}[x_1(y_2-y_3) + x_2(y_3-y_1) + x_3(y_1-y_2)]\\\Rightarrow A=\dfrac{1}{2}[2(5-0)+(-2)(0-5)+0(5-5)]\\\Rightarrow A=10\ \text{sq. units}[/tex]

Area of the triangle formed is [tex]10\ \text{sq. units}[/tex].

Answer: B. 59°F

Step-by-step explanation:

Range = Maximum - MInimum.

From the given temperatures, Maximum temperature = 99 degrees Fahrenheit

Minimum temperature = 40 degrees Fahrenheit

Range = Maximum temperature  - Minimum temperature

i.e. Range =99-40 = 59 degrees Fahrenheit

Hence, the range of the temperatures = 59°F i.e. B is the correct option.
