Complementary angles are angles whose measure add up to 90°.
So, if one angle is 4y, the complementary angle is 90°- 4y. Choice A.
Complementary angles does not necessarily need to share a line or vertex. As long as both angles have a sum of 90°, then, they are complementary angles.
Angles who has a sum of 180° are called supplementary angles.
13/17 is at the lowest because they are both prime numbers.
Answer:
2a) $180
2b) $1440
Step-by-step explanation:
2a) Basically Samuel works for 6 hours a day and earns 7.50 per hour, so you have to do 7.50 x 6 to see how much he earns per day (which in this case is $45). You then have to multiply $45 to 4 since he earns $45 per day and works 4 days per week (which is $180).
2b) After finding out how much he earns per week ($180 from the previous question), you then have to multiply $180 by 8 as $180 is the amount he earns per week and since he works for 8 weeks you have to multiply $180 by 8 (the answer is then $1440).
sorry if I'm not making sense, i tried :) good luck!
Answer:
600 beans
Step-by-step explanation:
If there are 300 pinto beans and the ratio is 1:1 there would have to be 300 black beans making 600 total.
Answer:
- 3/2 - 3/4
- 5/3 - 11/12
- 5/4 - 1/2
- 7/5 - 13/20
- 5/6 - 1/2
- 9/7 - 15/28
- 9/8 - 3/8
- 9/10 - 3/20
- 9/11 - 3/44
Step-by-step explanation:
We did a systematic search for subtraction problems of this type, eliminating ones that are too trivial, such as 1/1 - 1/4 and equivalents of those with integers added, such as 3/1 - 9/4. Even so, there are an infinite number of possibilities. some of the ones involving larger numbers in the range we looked at include ...
- 41/45 - 29/180
- 41/49 - 17/196
- 41/53 - 5/212
___
A reasonable approach to doing this by hand seems to be to choose a denominator for the minuend, then a denominator 4 times that value for the subtrahend. Express 3/4 using the latter denominator, and find two numbers that differ by that numerator, one of which is divisible by 4, but not by 8.
<u>Example</u>: Choose 13 as the minuend denominator. Then 52 is the subtrahend denominator, and the difference you need to create is 39/52. The smallest odd number we can add to 39 to make it divisible by 4 but not 8 is 5. So, we can use (39+5)/52 and 5/52 as our numbers that differ by 3/4. In reduced form, that subtraction is ...
11/13 - 5/52
Note that if you choose an even denominator, then the exact procedure will vary depending on what power of 2 is a factor of the denominator.
