3.
x = 3 because the 2 legs of 45-45-90 triangle are equal
y^2 = 3^2 + 3^2 = 18
y = sqrt 18 = 3 sqrt2
2 miles = 10560 ft.
10560 ft + 3241 ft = 13801 ft.
Answer:
$3 from his pockets
Step-by-step explanation:
Great question, it is always good to ask away and get rid of any doubts that you may be having.
To begin solving this problem we need to first calculate how much money all the supplies will cost. We do this buy adding up the prices of each individual supply. Like so,
Now we can see that the total amount of the supplies is $13. Since his mom loaned him $10 we can subtract that from the total cost.
Finally, we can see that Juan would need to pay a total of $3 from his pockets to be able to buy all the ingredients.
Answer:
1.97 ounces
Step-by-step explanation:
-The exponential decay function is given by the formula:

Given that the half-life is 4 days, we can substitute in the formula to solve the rate of decay for a single half-life:

#Since, 1 week has 7 days, 3 weeks is a 21-day period, thus, t=21.
#We substitute and solve for the amount remaining after 21days of decay:

Hence, the amount remaining after 3 weeks of decays is approximately 1.97 ounces
