To find the answer to this problem, you can use the unit circle to see that pi over 6 radians is equal to 30°
Another way is to use the equation: degrees = radians • (180 over pi)
In this example, plugging in the radians portion of the equation gives us: degrees = (pi over 6) • (180 over pi), which will become degrees = (180pi over 6pi)
Simplify and pi cancels out to give us degrees = 30
Answer: 30°
B: 16 and -16
two negatives = a positive
two positives make a positive :)
Answer:
The ODDS that the dart hits a date that is a prime number are 1:1
Step-by-step explanation:
Odds:
An odd is writen as:
Number of desired outcomes: Number of undesired outcomes.
In this question:
April has 30 days, 15 of which are prime numbers and 15 of which are odd numbers.
So the odds are:
15:15
Simplifying by 15
1:1
The ODDS that the dart hits a date that is a prime number are 1:1
Answer:30
Step-by-step explanation: LxW (length x Width) 3x10=30.... Hope this helps... if you break it down then you can write down (10) on your page but the answer is 30
Step-by-step explanation:
there are 2 similar triangles : ABE and DCE
that means they have the same angles, and the scaling factor from one triangle to the other is the same for every side.
and that means that
DE/AE = EC/BE (= DC/AB)
we know that
AE = AD + DE
BE = BC + EC
a.
so, we have actually
DE/(AD+DE) = EC/(BC+EC)
DE/(10+DE) = 8/(2+8) = 8/10 = 4/5
DE = 4(10+DE)/5
5DE = 4(10+DE) = 40 + 4DE
DE = 40 cm
b.
AD/DE = 3/5
BC/EC must be 3/5 too.
15/EC = 3/5
15 = 3EC/5
75 = 3EC
EC = 25 cm
