Step-by-step explanation:
1. if the mass of coffee worth $10 is 'x', then its worth is 10x, and the worth of the mixture is 5(x+20);
2. using the previous item it is possible to write the next equation:
5(x+20)=4*20+10*x; ⇒ x=4.
3. the required mass is 4 pounds.
Answer:
And the probability that the first die shows an odd number is 1/2, as is the probability that the second does. Since the dice fall independently, P(both are odd) = P(first is odd)*P(second is odd) = (1/2)*(1/2) = 1/4. Therefore P(at least one is even) = 1 - 1/4 = 3/4.

- Formula For Area Of Trapezoid:
-----------------------------------------
A = 10
B = 18
H = 6
- Plug Numbers Into Equation:
10 + 18 = 28
28 ÷ 2 = 14
14 · 6 = 84
84

<span>Mixed Numbers to Fractions uses circle models to demonstrate how a number in mixed form can be renamed in fraction form. The illustration below was made by Mixed to Fraction with Circles Designer. It shows the mixed number 2 2/5. You are to write 2 2/5 in fraction form, with only a numerator and denominator.</span>
It is quite simple really
