Answer:
47.856
Step-by-step explanation:
We will use
SOH
CAH
TOA
to solve this
we have the adjacent length, but need the hypotonouse
which means that we will use CAH
we have
cos(43)= 35/p
solve for p
47.856
Area =
Area = 22/7 x 10 x 10
Area = 314 in^2
(the answer is option A, its rounded)
Hope this helps
Answer:
Question 1: 0.38, 3/8, 25%
Question 2: 72oz.
Question 3: 165
Step-by-step explanation:
First Question: We can make all the numbers to decimals. 25%= 0.25, 3/8= 0.375, and 0.38 is given. Then we can clearly see that 0.38, 3/8, 25% is the order.
Second Question: There are 16oz. in a pound, so we have to multiply 4.5 and 16. 4.5*16 = 72. There are 72 oz. in 4.5lbs.
Third Question: We just have to plug 5 in, so 7(5)^2 - 10 is our equation. Following the order of equations, we have the exponent first. 5^2 is 25. We end up with 7(25) - 10. Then we have to multiply, so 7*25 = 175. Finally we have 175 - 10 which is 165.
Let 1993 = time 0 = 0.
Let 1999 = time 6 = 6
Let 2012 = time 19 = 19
So, a = 171 (million). First solve for k.
176 = 171 e^k6
176/171 = e^(k*6)
ln (176/171) = 6k
k = 1/6 ln (176/171)
So, in 2012 we have: P(19) = 171 e^(19k), where k = 1/6 ln (176/171)
Hope this helped!
