Answer:
the answer is a 20% increase
Step-by-step explanation:
first, you have to find the amount of change (how much her points scored increased
second , you would divide which equals 0.2
then you would multiply by 100 or move the decimal two places to the right
which would equal 20%
This is a mixture problem.
Let the 9 karat gold to be mixed be x. The 18 karat would weight (200 - x). Since the total = 200g.
mass1 * karat1 + mass2*karat = total mass * total carat
Let mass1 be x g. mass 2 would be = (200 -x)
karat 1 = 9 karat 2 = 18
Total mass = 200g.
Total karat = 14.
9*x + 18*(200 -x) = 14*200
9x + 18*200 - 18*x = 14*200
18*200 + 9x - 18x = 14*200
3600 - 9x = 2800
3600 - 2800 = 9x
800 = 9x
9x = 800
x = 800/9
x ≈ 88.89
Therefore 88.89 grams of 9 karat gold must be mixed.
Answer:
add 7 to 9 times k : 7+9k
c cubed minus the product of 5 and q plus 4 :
twice r plus 7 is equal to 45 minus r : 2r+7=45-r
Product of h and 4 is subtracted from one-fifth of x is 35 :(h*4) - 1/5*x
one third of the difference bewteen 6 and p is added to 8 : (6-p)+8
Answer:
-pi/3
Step-by-step explanation:
To convert from degree to radians, multiply by pi/180
-60 * pi/180 = -60/180 *pi = -pi/3
