Answer:
The number of liters of 50% antifreeze solution is 50 and the number of liters of 90% antifreeze solution is 150
Step-by-step explanation:
Let
x ----> number of liters of 50% antifreeze solution
y ----> number of liters of 90% antifreeze solution
we know that
50%=50/100=0.50
90%=90/100=0.90
80%=80/100=0.80
x+y=200
x=200-y ------> equation A
0.50x+0.90y=0.8(200) -----> equation B
substitute equation A in equation B and solve for y
0.50(200-y)+0.90y=160
100-0.50y+0.90y=160
0.40y=160-100
0.40y=60
y=150 liters
Find the value of x
x=200-y
x=200-150=50 liters
therefore
The number of liters of 50% antifreeze solution is 50
The number of liters of 90% antifreeze solution is 150
You divide by 16 so you can get each ingredient per serving then you multiply that by 4 and you get your answer
Answer:
The answer is 40 because you have a ratio of 4:1 (16:4). If you multiply by ten, it becomes 40:10.
Step-by-step explanation:
Answer:
Last option.
Step-by-step explanation:
The consecutive exterior angle theorem states that the exterior angles are supplementary if two lines are cut by a transversal.
m∠1 + m∠7 = 180
m∠2 + m∠8 = 180
The bottom one
That should be correct!!!
