Answer:

Bus B travels faster.

Step-by-step explanation:

Bus A travels according to the equation

y = 125/2 x

This equation is in the form y = mx + b, where m = 125/2, and b = 0.

m is the slope, so the slope is 125/2 which equals 62.5

The slope is the rate of change. Since y is distance in miles, and x is time in hours, the slope is the speed in miles per hour.

The speed of Bus A is 62.5 miles per hour.

Bus B travels according to the graph. We can find the slope by using easy-to-read points on the graph. The slope is the speed in miles per hour.

Look for two points on grid line intersections since they are the easiest ones to read. Let's use point (0, 0) and point (3, 200). Now that we have 2 points, we can find the slope.

slope = \dfrac{y_2 - y_1}{x_2 - x_1}

slope = \dfrac{200 - 0}{3 - 0}

slope = \dfrac{200}{3} = 66.67

The speed of Bus 2 is 66.67 miles per hour.

Answer: Bus B travels faster.

Find the area of the regular polygon. Round to the nearest tenth.
JulsSmile [24]

Answer:

110.9\ ft^{2}

Step-by-step explanation:

we know that

If the triangle of the figure is a regular polygon

then

Is an equilateral triangle

Remember that

The equilateral triangle has three equal sides and three equal interior angles

The measure of each interior angle is 60 degrees

To find the area of the equilateral triangle apply the law of sines

A=\frac{1}{2} b^{2}sin(60\°)

we have that

b=16\ ft

substitute

A=\frac{1}{2} (16^{2})sin(60\°)=110.9\ ft^{2}

A video game randomly chooses your car color and type. The probability of getting a red car is 0.25, and the probability of gett
EleoNora [17]

In probability 2 events are independent if the occurrence of 1 event does not affect the occurrence of the other event. Mathematically, if event A and event B are independent, then P(A\&B)=P(A)\times P(B). For our two events in this problem we have that P(A)=0.25 and P(B)=0.40. If these two events are independent, then we should have that,

P(A\&B)=P(A)\times P(B)\\P(A\times B)=0.25\times 0.4=0.1.

.A and B are independent events if the probability of A and B is 0.1

17. x^2 + 2x + 1
valentina_108 [34]

Answer:

E. This polynomial could be factored by using grouping or the perfect squares methods.

Step-by-step explanation:

x^2 + 2x + 1

There is no greatest common factor

This is a perfect square

a^2 + 2ab+ b^2 = ( x+1)^2

We can factor this  by grouping

x^2 + 2x + 1

(x^2 +x) + (x+1)

x( x+1)  + x+1

Factor out x+1

( x+1)  ( x+1)

This is not the difference of squares since there is no subtraction

const2013 [10]
23. The answer is D. If you multiply 0.8 by 5 you get 4 meters which means it would take 5 minutes. Multiplying it by 5 will give you a whole number therefore easier to find on the graph.

24. The answer is G. The square root of 5 is 2.23 and the square root of 2 is 1.4
