An automobile traveled 106 miles in 2 hours. What was average speed? Use the formula d = rt .
104 mph
0.02 mph
53 mph
108 mph
212 mph
The average speed of the automobile is 53mph.
Description of average speedAverage speed is the total distance travelled by the automobile (106 miles) divided by the total hours travelled by the automobile (2 hours). It is the rate of the movement of the automobile.
Determining the average speedAverage speed = total distance travelled / total time travelled
106 / 2 = 53 mph

Stephen Kiprotich, the 2012 Olympic marathon winner, completed the 26.219 miles in 128 minutes. What was his speed in kilometers per minute? PLS HURRY IM RUNNING OUT OF TIMEEEEE
Answer:
0.127 kilometers per minute
Step-by-step explanation:
if you can divide the number of miles by the number of minutes: 26.219/128 = 0.205 miles per minute. Next, we can use the proper conversion factor to give the number of kilometers per minute. Since 1 mile = 1.609 km, you can divide 0.205/1.609 to result in 0.127 kilometers per minute
Answer:Sample Response: Find the speed by dividing 26.219 by 128. Convert miles to kilometers by multiplying by the conversion factor, with miles in the denominator and kilometers in the numerator.

Jake ran 5/7 of the distance around the school tack. Annabelle ran 4/5 of Jake's distance. What fraction of the total distance around the track did Annabelle run?
Answer: 4/7
Step-by-step explanation:
Multiply 5/7 by 4/5. The keyword is "of" which means multiply. Once you multiply them, you will get 20/35. You can simplify this to 4/7.

This 3D solid is a strange sideways bowl shape. Each cross section is a ring to show the empty space.
======================================================
Explanation:
Check out the diagram below. The graph was created with GeoGebra. We have y = x^2 in red and x = y^2 in blue.
The gray region is the region between the two curves. We spin this gray region around the horizontal green line y = 1 to generate the answer mentioned above.
Note how (1,1) is a fixed point that does not move as this is on the line y = 1. Every other point moves to sweep through 3D space to create the solid figure. One way you can think of it is to think of propeller blades. Or you can think of a revolving door (the door is "flat" so to speak, but it sweeps out a 3D solid cylinder).

Step-by-step explanation:
I got it right on the test
The value of the given expression is i.
We want to simplify the expression [tex]i^{41}[/tex].
What is an imaginary number?An imaginary number is a real number multiplied by the imaginary unit i, which is defined by its property i² = −1. The square of an imaginary number bi is −b².
The given expression [tex]i^{41}[/tex] can be written as [tex](i^{4})^{10}.i[/tex]
The value of i²=-1, then [tex]i^{4}[/tex]= i².i²=(-1)(-1)=1
Now, [tex](1)^{10}.i=1\times i=i[/tex]
Therefore, the value of the given expression is i.

How can you match up the disk and the given information?
Answer: The first diagram you selected is the correct visual representation.
Check out the diagram I posted below. The red vertical line is x = 0, aka the y axis. The blue parabola is 3x = y^2. The green horizontal line is y = 6. The region bounded by these curves is the gray shaded region.
Spinning that gray region around the y axis results in the first diagram in your answer choices. The disk in pink is a cross section to help find the volume (through the use of integral calculus).

Which polynomial is prime? x2 + x + 1 x2 – x – 2 x2 – 12x + 11 x2 + 2x – 8
Answer:
[tex]x^{2} +x+1[/tex]
Step-by-step explanation:
[tex]x^{2} +x+1[/tex] is the only prime polynomial because the others can be factored.
[tex]x^{2} - x -2 \\becomes (x-2)(x+1)[/tex]
[tex]x^{2} -12x+11\\becomes (x-11)(x-1)[/tex]
[tex]x^{2} +2x-8\\becomes (x+4)(x-2)[/tex]
In between these four polynomials, x² + x + 1 is the only prime polynomial.
What is a prime polynomial?A prime polynomial doesn't have any factor except 1 and itself.
Given,
x² + x + 1 = 1 × (x² + x + 1)
x² – x – 2 = x² - 2x + x - 2 = x(x - 2) + (x - 2) = (x - 2)(x + 1)
x² – 12x + 11 = x² – 11x - x + 11 = x(x – 11) - (x - 11) = (x - 1)(x - 11)
x² + 2x – 8 = x² + 4x – 2x - 8 = x(x+4) - 2(x+4) = (x-2)(x+4)
Therefore, x² + x + 1 is the only prime polynomial here.
