Step-by-step explanation:
Let x and y pounds of Candy A and Candy B be mixed respectively.
Rate of Candy A and Candy B are $0.78 and $1.33 per pound respectively.
Now,
(A) x + y = 8
(B) 0.78x + 1.33y = 7.84
Solving both equations :
0.33y = 1.6
x = 3.16 pounds of Candy A
y = 4.84 pounds of Candy B
The formula of a density is
p = M/V
where p is a density, M is a mass and V is a volume.
Given M = 3.4 kg and V = 2,300 mL or 2,300 cm<span>³, therefore
</span>p = 3.4 kg / 2,300 cm³ = 1.48 x 10⁻³ kg/cm³
Answer:
you have to give the context.
Step-by-step explanation:
Data on first test: 50, 50, 50, 50, 50
Mean = 250 / 5 = 50
In the next test, Data is: 50, 50, 50, 50, 100
Mean = sum of data / number of data
Mean = 50 + 50 + 50 + 50 + 100 / 5
M = 300 / 5
M = 60
In short, Your Answer would be 60
If You're looking for combined progress (average of class then, it would be: 50 + 60 /2 = 110/2 = 55
Hope this helps!
