Answer:
Step-by-step explanation:
This parallelogram contains a right angle. This tells us that the parallelogram is a rectangle.
The diagonals in a parralelogram bisect each other.
The diagonals in a rectangle are congruent.
Answer:
Step-by-step explanation:
5/7m=-55
1.) First of all they are multiplying so you do the opposite. In this case you divide 5/7 by both sides.
-55divided 5/7
Changes to
-55/1 x 7/5. See if you can cross cancel in this case you can. The -55 changes to a -11 and the 5 changes into a 1
Reminder: Remember when you divided by fractions you change the sign to a multiplication sign and then flip the next fraction over.
2.) After dividing you should get -77/1 or if you didn't cross cancel then you would get -385/5.
3.) If you get -385/5 then you would have to do 385 divided 5 and you would get -77.
4.) Checking your answer is 5/7•-77=-55.
5/7•-77 changes to 5/7•-77/1 and you can cross cancel it where the -77 changes to a -11 and 7 changes to a 1.
5.) You should get -55. If you didn't cross cancel then you would have gotten -385/77
6.) If got -385/77 then you would do -385 divided by 77. Your then should get -55.
7.) Look to see if the answer you got when you checked matches the answer in the problem. -55=-55
8.) Your answer is -77
Answer:
A right circular cone can be intersected by some plane to produce circle, ellipse, hyperbola depending upon where the plane is crossing the cone.
But if the plane crosses at the vertex. Just one point is crossed.
Answer:
≈ 452.5 rpm
Step-by-step explanation:
First convert mph to in/min.
35 mi/hr × (5280 ft/mi) × (12 in/ft) × (1 hr / 60 min) = 36960 in/min
The diameter of the wheel is 26 inches, so the circumference of the wheel is 26π inches. So the revolutions per minute is:
36960 in/min × (1 rev / 26π in) ≈ 452.5 rpm
