How many cups of 25% fruit juice?
Answer:
4 cups of 75% fruit juice and 4 cups of 25% fruit juice should be mixed.
Step-by-step explanation:
Suppose, the amount of 75% fruit juice is cups.
As the total amount of fruit punch is 8 cups, so the amount of 25% juice will be: cups.
Given that, the percentage of juice in 8 cups fruit punch is 50%
So, the equation will be.........
Thus, the amount of 75% fruit juice is 4 cups
and the amount of 25% fruit juice is (8-4)= 4 cups.
Answer:
126
Step-by-step explanation:
Do operations in BEDMAS order. Whatever is inside brackets is always solved before outside.
6(25-4) Solve inside the brackets first
= 6(21) Multiply
= 126
The mass of the silver ingot is found by multiplying its volume with the density of metallic silver. The volume is calculated using the ingot's dimensions, and the final mass is approximately 5186.16 grams.
To determine the mass of a silver ingot based on its dimensions and density, we can use the formula mass = density × volume. First, we calculate the volume of the ingot by multiplying its length (28.0 cm), width (4.90 cm), and thickness (3.60 cm):
Volume = length × width × thickness
= 28.0 cm × 4.90 cm × 3.60 cm
= 493.92 cm³
Next, we use the density of metallic silver, 10.50 g/cm³, to find the mass:
Mass = density × volume
= 10.50 g/cm³ × 493.92 cm³
= 5186.16 g
The mass of the silver ingot is therefore approximately 5186.16 grams.
#SPJ2
Answer:
5190 g
Step-by-step explanation:
Calculate the volume:
28.0 cm × 4.90 cm × 3.60 cm = 493.92 cm³
Density is mass divided by volume:
D = M / V
Solving for mass:
M = D V
Substituting values:
M = (10.50 g/cm³) (493.92 cm³)
M = 5186.16 g
Rounding to three significant figures, the mass is 5190 g.
