0.05n + 0.1d = 3.10
n + d = 44
d = 44 - n
Substituting to the first equation:
0.05n + 0.1(44 - n) = 3.10
0.05n + 4.4 - 0.1n = 3.10
-0.05n = 3.10 - 4.4
n = 26
Obtaining the value of nickels:
26 * 0.05 = 1.3
Therefore, the value of nickels that Bethany has is $1.30
Answer:
$7,428.46
Step-by-step explanation:
A = 7000(1 + .02)³
A = 7000(1.02)³
A = 7000(1.0612)
A = $7,428.46
Irrational
the number is endless in its digits (much like pi) and thus is irrational
The measure of the sides is 27, 23 and 16 and the perimeter is 56 respectively
<h3>The perimeter of a triangle</h3>
The triangle is a 2 dimensional shape that has 2 sides.
Given the following sides
l = m + n - 12
n = m - 7
m = l - 1/4n
l = m + 1/4n
Substitute
m + 1/4n = m + m - 7 - 12
m + 1/4(m-7) = 2m - 19
m + 1/4m - 7/4 = 2m - 19
-m + 1/4m = -19 + 7/4
-3/4m = -19(4)+7/4
-3/4m = -69/4
-3m = -69
m = 23
Hence the value of m from the given expression is 23
n = 23 - 7
n = 16
l = 23 + 16 -12
l = 39 - 12
l = 27
n = 23 - 7
n = 16
Hence the measure of the sides is 27, 23 and 16 respectively
Perimeter = 27+23+16
Perimeter = 56

Rolling a sum of seven with a pair of dice...any of the six numbers can be first so that probability is:
(6/6) or 1 :P
Now to roll a sum of seven only one unique number can follow the first so the probability of getting that unique number so that you have a sum of seven is:
(1/6)
This is a compound event because two thing must happen and you multiply their respective probabilities to get the probability of the compound even..
(6/6)(1/6)=6/36=1/6
