Answer:
Not sure if this is exactly the same,but hopefully it answers your questions.
Answer:
12 nickels and 13 dimes
Step-by-step explanation:
d = # of dimes
n = # of nickels
Set up a System of Equations as follows:
d + n = 25
.10d + .05n = 1.90
now solve for 'd' or 'n' and use Substitution:
d = 25-n
.10(25-n) + .05n = 1.90
2.5 - .10n + .05n = 1.90
-.10n + .05n = -0.6
-.05n = -0.6
n = -0.6/-.05
n = 12
d + 12 = 25
d = 13
Check: 12(.05) + 13(.10) should equal 1.90
0.60 + 1.30 = 1.90
1.90 = 1.90
Answer:
61.93 will be measure of angle p
Step-by-step explanation:
as cos(p) = (8/17)
p = 61.93
Step-by-step explanation:
1. 250×4=1000
2.125×8=1000
3. 25×40=1000
4. 500×2=1000
5. 200×5=1000
6. 50×20=1000
If you're looking for the simplified version of the fraction, you have to factor both numerator and denominator.
The numerator is actually already a prime number, so we're good
The denominator factors as 
So, a 3 appears in both numerator and denominator. We can simplify it:
If you want to compute the approximated value of this fraction, simply plug these values into some calculator to get
