Yes, very fun, not
ok
one way is table or
solutions amount x and y
x+y=500
x=25%
y=50%
0.25x+0.5y=0.35(500)
we have
x+y=500
0.25x+0.5y=0.35(500)
0.25x+0.5y=175
solve
multiply second equation by 100
25x+50y=17500
divide everybody by 25
x+2y=700
now we have
x+y=500
x+2y=700
multiply first equation by -1 and add to second equaiton
-x-y=-500
<u>x+2y=700 +</u>
0x+1y=200
y=200
sub
x+y=500
x+200=500
x=300
300L of the 25% and 200L of the 50%
Answer: d. 10
Step-by-step explanation:
We know that the number of combinations of r objects selected from a group of n objects at a time is given by :-
Given : The total number of letters = 5
The number of letters need to select = 2
Then , the number of combinations of 2 letters selected from a group of 5 letters at a time is given by :-
Hence, there are 10 possible selections.
-4 - 7 divide 8n thats the answer
The area of a square is expressed as the length of the side to the power of two, A = s^2. We were given the area of the enlarged photo which is 256 in^2. Also, it was stated that the length of the enlarged photo is the length of the original photo plus ten inches. So, from these statements we can make an equation to solve for x which represents the length of the original photo.
A = s^2
where s = (x+10)
A = (x+10)^2 = 256
Solving for x,
x= 6 in.
The dimensions of the original photo is 6 x 6.
32^2 +24^2 = 1600
Square root of 1600 = 40
b = 40.
More info needed for a and c.
