Answer:
c ≈ 5.8 units
Step-by-step explanation:
Calculate c using the distance formula
d = 
with (x₁, y₁ ) = (2, - 1 ) and (x₂, y₂ ) = (- 1, 4 )
c = 
= 
= 
= 
=
≈ 5.8 units ( to the nearest tenth )
Answer:
-$36
Step-by-step explanation:
Daniel has a starting balance of $259, so anything he spends will be deducted by this amount. To find out how much he spent, we need to add up everything he bought.
He spent $45 + $150 + $100, adding to a grad total of $295.
To find out how much money Daniel has left, we need to subtract his purchases from his funds. This would be $259 - $295. This leaves you with a final answer of -$36 in Daniel's bank account.
Answer:
See solution below.
Step-by-step explanation:
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
