Answer:
16, 18, 20
Step-by-step explanation:
We can estimate that the square of the middle integer will be about 1/3 of 980. Then the middle integer is about ...
√(980/3) ≈ 18.09
The integers are 16, 18, 20.
_____
<em>Check</em>
16^2 +18^2 +20^2 = 256 +324 +400 = 980
Answer:
Answer:
The total is: $ 1345.5
Step-by-step explanation:
It is given that:
I would like to purchase 20 products at a cost 65.00 per product.
This means that the cost of 20 products will be:
Also, there is a sales tax of 3.5%
This means that a person has to pay a extra 3.5% on the total cost of the items he purchased.
i.e. he need to pay 3/5% on $ 1300
This means that the amount of tax he need to pay is: 3.5% of 1300
= 3.5%×1300
= 0.035×1300
= $ 45.5.
Hence, the total cost is: $ 1300+$ 45.5
This means that the total cost is: $ 134.5
Xn = ar^(n-1)
n = term to find = 6
a = 1st term = 72
r = common ratio = 0.5
now we sub
x6 = 72 * 0.5^(6-1)
x6 = 72 * 0.5^5
x6 = 72 * 0.03125
x6 = 2.25 <===
Answer:
x=66
Step-by-step explanation:
35-13=22
22*3=66
x=66
