If a coin rotates 160 degrees in 6 seconds,how many degrees does it rotate in 20 seconds?
Answers
Answer 1
Answer:
Okay so this is how I would do it but you can do it a different way 160/2 = 80 (2 b/c I want a whole # and 2 is a factor of 6 & 20) so 80 degree in 2 seconds so then 80 *10=800 (10 b/c 20/2=10) but since there's only 360 degrees in a full circle 800/360=2.22 so we go back to 80 *2.22=177.6 degrees ----------------------------------------------------------------------- v.s. 160 n ---- * --- (20 *160=3200/6=533.33 6 20
You can go w/ whatever answer you think is right b/c frankly I don't know but if I were you I would go with the second one because it seems more right and there's actually a method to the madness.
First you ask yourself, can 8 go into 1? The answer is no. Can 8 go into 12? Yes, 1 time. So you put 1 on top of the 2 and subtract 8 from 12. That gives you 4. Then you pull down the 8 from 128 and ask how many times can 8 go into 48? The answer is 6. So your answer is 16. Hope I helped!
You can divide 128 by 8 and it would equal 16
What is m CBT? Use a protractor to help you.
Answers
m∠CBT is not 120°.
You have to notice the start of the measure of the angle is on the point of C. It is the 0°.
If the segment BT is straight up from the point of B, its angle will be 90°.
Since the segment does not form a right angle, its measure of angle is less than 90° but more than 0°
The sides of one right triangle are 6, 8 and 10. The sides of another right triangle are 10, 24 and 26. Determine if the triangle are similar. If so, what is the ratio of corresponding sides
Answers
corresponding sides are 6,10 8,24 10,26 now my question is these numbers out side the triangle or in side cuz if so in side u need the out side numbers to determine if is similar or not add the out side numbers then subtract it from 180 to get ur 3rd missing number in the triangle now if there more than 2 triangle wich of (how ever many u got) of triangles find the ones in wich have to the same numbers sooo for example if there's 3 triangles one big one medium and one large find the corresponding sides of the 3 triangles is step one then there should be a missing number in all three triangles add the to first in the triangle then subtract it from 180 to get the missing number then you can determine if the correspond or not then you need to take that outside measures that correspond and put them in the fraction then you will simplify it with the greatest number that can divide the two numbers in the fraction
What is 3/7 rounded to the nearest 1/2
Answers
this means that we are just trying to find 1/2 of 3/7 i believe so first lets set up our fractions to multiply them 3 1 --- x --- 7 2 now we just multiply across :)
3 1 = 3 x 1 = 3 --- x --- 7 2 = 7 x 2 = 14 so our new fraction issss
