let a be aluminum and g be gold and k how many times:
2*10⁻¹mg a+ 6*10¹mg g= 154 lb
so a=kg
k=a/g
k=2*10⁻¹/6*10=1/300
a=1/300g
so Aluminum is 1/300 of gold.
Answer:
Carole's situation : 2x + 11y = 196
Michele's situation: 10x + 11y = 276
Step-by-step explanation:
If x = cost of 1 cupcake, then 2x = cost of 2 cupcakes and 10x = cost of 10 cupcakes, et.
If y = cost of 1 sugar cookie, then 11y = cost of 11 sugar cookies.
Carole's situation : 2x + 11y = 196
Michele's situation: 10x + 11y = 276
Answer:
$3530.3541
Step-by-step explanation:
Given that:
Principal = 2200
Interest rate compounded annually (r) = 3%
Time (t) = 16 years
Using the compound interest formula :
A = P(1 + r/n)^n*t
A = final amount
n = number of times interest is applied per period
A = 2200(1 + 0.03)^16
A = 2200(1.03)^16
A = 2200 * 1.60470643909878751793
A = $3530.3541
Hence, amount in account on his 16th birthday will be $3530. 3541
Answer:
a= 1
b= 0
Step-by-Step Explanation:
I am not 100% sure on part A, however part B is correct because the difference between -2 and -1 is 1, so if you add 1 to -1 you get 0. Hence B= 0.
Again I am not 100% sure on part A, so you may need a second opinion.
Answer:
Step-by-step explanation:
