Answer:
0.7 gallons, 950 mL, 0.4 L, 1 1/4 cups
Step-by-step explanation:
First we need to convert the information given into one unit, in this case I will convert it into liters (L)
CUPS
1 cup is equal to 236.588 ml and is the same as .236 L using this information and knowing that 1 1/4 cup is the same as 1.25 cups we have that
x=.295 L
LITERS
0.4 L will stay the same
MILILITERS
1 liter is 1000 ml so 950 ml is the same as
x=.950 L
GALLONS
1 gallon is 3.78541 L so 0.7 gallons are
x=2.649 L
arranging the data from greatest to least we have that 0.7 gallons, 950 mL, 0.4 L, 1 1/4 cups
Answer:
1.39
Step-by-step explanation:
According to the problem, calculation of the given data are as follows,
Given equation = 0=2x2+3x-8
Here, we use general formula of quadratic equation, then
By taking the value by given equation,
a = 2, b = 3, c= -8
by putting the value in equation , we get
x = [- 3 ± √3^2 - 4(2 × -8)] ÷ 2×2
= [- 3 ± √73] ÷ 4
= [- 3 ± 8.544] ÷ 4
So, for positive solution, we get
x = (-3 + 8.544) ÷ 4
x = 1.386 or 1.39
