Answer:
106
Step-by-step explanation:
c(106)=x^(2)-17x+66
u put 106 into the formula by squaring 106 which gives you 11236
timesing 17 x 106 = which is 1802
then the formula looks like this c(106)=11236-1802+66
this then equals $9500, meaning the answer is 106

Answer:
x = -3, y = 2
Step-by-step explanation:
x - y = -5
x = -5 + y
Let's put this into the other equation
(-5 + y) + y = -1
-5 + 2y = -1
2y = 4
y = 2
Now we can solve for x by plugging y into either equation
x + (2) = -1
x = -3
$30.76
Find 7% of $25 = (25/100) x 7 = 1.75, then add it to $25 because it's applied tax.
25 + 1.75 = $26.75
15% = split into 10 and 5 percent
10%= (26.75/10) = 2.675
5% = 1.3375, make sure you add this all in your working out.
2.675 + 1.3375 = 4.0125
4.0125 + 26.75 = 30.7625 then round it to two decimal places because it's money :)
So the area of a circle is pi x the radius squared.
To find the radius we need to half the diameter so 2.85mm
Next we need to square this so 2.85 x 2.85 = 8.1225mm
The area = pi x 8.1225
= 25.51758633mmsquared
= 25.5 mmsquared

Answer:
32 coins
consider the value of a group of coins
Step-by-step explanation:
The coins are in equal numbers, so they can be considered as a group. The value of one group of 4 coins is ...
1¢ + 5¢ + 10¢ + 25¢ = 41¢ = $0.41
Then the number of groups (g) of coins is ...
$3.28 = $0.41×g
g = $3.28/$0.41 = 8
There are 8 groups of coins. Each group has 4 coins, so there are ...
(8 groups)×(4 coins/group) = 32 coins
