A snowmobile traveled 32 miles in 213 hours.

patriot [66]

The average speed of the snowmobile can be obtained by using the formula: speed = distance/time which was also given in the problem statement. This means that the average speed refers to how far you have traveled in a period of time. In this case, the snowmobile traveled 32 miles in 213 hours. We then simply divide the distance, 32 miles, by the time it took for the snowmobile to travel such distance which is 213 hours. The average speed of the automobile is calculated to be 0.1502 miles per hour. When rounded off to the nearest tenth, the final answer is then 0.2 miles per hour.

Which one of the following is not closed under the operation being performed

Sergeu [11.5K]

Remember that polynomials are closed under addition, subtraction, and multiplication, but they are not closed under division. The only division you have there is B; therefore the correct answer is B.

A. $(14x-2)3(x-2)=14 x^{2} -90x+10$ . The result is still a polynomial; therefore, answer A is incorrect.

B. $\frac{(14x-2)}{3(x-2)} = \frac{14}{3}$ with a remainder of 26. The result is not a polynomial anymore; therefore, B is the correct answer.

C. $(14x-2)+3(x+2)=17x+4$ . The result is still a polynomial; therefore, answer C is incorrect.

D. $(14x-2)+3(x+2)=17x+4$ . The result is still a polynomial; therefore, answer D is incorrect.

Answer:

(c) The volume of a rectangular pyramid is 1/3 the volume of a rectangular prism. The volume of the rectangular pyramid is 66 cm3.

Step-by-step explanation:

The pyramid with the same overall dimensions will obviously have a smaller volume. The ratio is 1/3.

The formula for the volume of a rectangular prism is ...

V = LWH

The formula for the volume of a rectangular pyramid is ...

V = (1/3)LWH

The pyramid has 1/3 the volume of the prism.

Y= 4x-1 is the equation of a straight line graph. What is its gradient?

Dima020 [189]

When a straight line is given the form:

$y=mx+c$

m is the gradient. It shows how the value of y changes for an increase of x by 1.

So, in this case, the gradient is 4
