For the restaurant to make 20 gallons of a lemonade mixture that is 10% sugar, they need 12 gallons of the 12% lemonade and 8 gallons of the 7% lemonade. The correct answer is A.
75 mph because you divide 337.5 by 4.5
It would be 11 because you would add the x's and divide it by 55. 55/5=11
Answer:
Step-by-step explanation:
To convert from degrees to radians, you simply multiply the value of by
Take for an example,
To convert 45 degrees to radians,
The discriminant is the part under the sqrt in the quadratic formula
for ax²+bx+c, the discriminant is b²-4ac
if the discriminant is
less than 0, then there are non-real roots
equal to 0, then there is a double root
greater than 0, then there are 2 real roots (may be rational or irrational)
so
1x²-5x+7
b²-4ac=(-5)²-4(1)(7)=25-28=-3
less than 0 so it is non real roots
answer is D
