Just Trying to get points
Just add Vickie and Hannah's scores together. Simple addition problem. You end up with 3056+1686=4742.Final answer is 4742 points.
1) tan 41°= 30cm divide by y cm
y= 30 divide by tan-1 41°
Remember that exponentioal rule
x^m times x^n=x^(m+n)
therefor
7^4 times 7^-6=7^(4-6)=7^(-2)
remember the other rule
x^-m=1/(x^m) so
7^-2=1/(7^2)=1/49
answe ris A
First find how many units of solution there is:
500* 2% = 500(.02) = 10 units
You need 10 units of solution in 'x' units of a 10% solution.
x*10% = 0.1x = 10 units -----> x = 10/0.1 = 100
100 units are needed
