Answer:
50 trays
3000 cookies
Step-by-step explanation:
We are given the following in the question:
1 cup of brown sugar and 
cup of granulated sugar makes a tray of 60 cookies.
Total cups of sugar used(brown and granulated) = 1.5 cups
Number of sugar cups used by Lyle each week = 75
We have to find the number of trays made each week.
Thus, 50 trays of cookies are made each week.
Total number of cookies made each week =
Thus, 3000 cookies are made each week.
Solve for z a(t+z)=45z+67
1. Expand
2. Subtract
from both sides
3. Subtract 45z from both sides
4. Factor out the common term z
5. Divide both sides by a - 45
Answer: 
Answer:
cosA = 7/8
Step-by-step explanation:
cos∅ = adjacent over hypotenuse
cosA = 14/16
cosA = 7/8
Answer:
<em><u>The final atmospheric pressure is 5.19 · 10⁴ Pa</u></em>
Step-by-step explanation:
Assuming that the temperature of the air does not change, we can use Boyle's law, which states that for a gas kept at constant temperature, the pressure of the gas is inversely proportional to its volume. In formula,
pV = const.
where p is the gas pressure and V is the volume
The equation can also be rewritten as
p₁ V₁ = p₂ V₂
where in our problem we have:
p₁ = 1.03 · 10₅ Pa is the initial pressure (the atmospheric pressure at sea level)
V₁ = 90.0L is the initial volume
p₂ is the final pressure
V₂ = 175.0L is the final volume
Solving the equation for p2, we find the final pressure:
p₂ = p₁ v₁ divided by V₂ = (1.01 · 10⁵)(90.0) divided by 175.0 = 5.19 · 10⁴ Pa
