Answer:
5.6
Step-by-step explanation:
by dividing
Answer: A.
Step-by-step explanation:
You multiply the constants (2 and 4), then multiply the variables. To multiply variables raised to a power, you keep the variable (k) the same, and add the exponents. 2 x 4 =6....... k^4 x k^1 = k^5
Answer:
3,717,000
Step-by-step explanation:
The calculation of paperback copies is shown below:-
Let us assume hardback copies is x, so paperback copies will be 9x
now the equation is
35,000 + x + 9x = 448,000
10x = 448,000 - 35,000
10x = 413,000
= 41,300
Therefore, the paperback copies are
=
= 3,717,000
Hence, the paperback copies is 3,717,000
Answer:
The approximate growth rate of the savings account is 2.5%
Step-by-step explanation:
Given the the function S(x) = 5, 000 * (1.025) ^ (0.7x)
From the function, we can see that part: (1.025). It presents for the growth factor or rate with the formula as:
(1 + r) where r is rate
So we have:
(1 + r) = 1.025
<=> r = 1.025 -1
<=> r = 0.025
In pecentage, we have the rare: 0.025 *100% = 2.5%
So the approximate growth rate of the savings account is 2.5%
Answer:
1
Step-by-step explanation:
1/15 + 7/30y + 1/2y = 4/5
2 + 7y + 15y = 24
2 + 22y = 24
22y = 24 - 2
22y = 22
