Answer:
4250
Step-by-step explanation:
5000 packs of gum were produced by the factory.
85% of them contained mint-flavoured gum.
That is,
(85/ 100) × 5000 packs contained mint-flavoured gum.
= 85 × 50
= 4250.
Answer:
Out of 5000 packs, 4250 contained mint-flavored gum.
0.7, 70% are a equivalent decimal and percent
Ok so first we need to write a fraction.
75 percent/45 mins
then we convert that into a unit rate
1.67 percent/1 min
so, now that we have the unit rate, we know exactly how fast she is moving.
Now, we divide 25 by 1.67 because 25% is the distance between the completion of the gate and current state of the gate.
So we get 14.97, which we can safely round up to 15.
It will take her 15 mins more to finish the gate, and it has already taken 45, so 45+15=60
60 MINS TOTAL/ 1 HOUR
The easiest way to answer this is to try all choices, plug
in values for the 1st term and 2nd term then check if the
answer matches with 5 and 2. (n = 1 and n = 2)
We know that n starts with 1 because that is our 1st
term, we do not have 0th term, therefore that leaves us with 2
choices.
Choice 1: an = 5 − 2(n − 1); all integers where n ≥ 1
n = 1
a1 = 5 – 2 (1 – 1) = 5 – 2 (0)
a1 = 5
n = 2
a2 = 5 – 2 (2 – 1) = 5 – 2 (1)
<span>a2 = 3 (FALSE!)</span>
Choice 2: an = 5 − 3(n − 1); all integers where n ≥ 1
n = 1
a1 = 5 – 3 (1 – 1) = 5 – 3 (0)
a1 = 5
n = 2
a2 = 5 – 3 (2 – 1) = 5 – 3 (1)
<span>a2 = 2 (TRUE)</span>
Therefore the correct answer is:
<span>an = 5 − 3(n − 1); all integers where n ≥ 1</span>
Right away, you can tell that the number is greater that one if the exponent is positive. For example, 1.23 x 10 to the power of 2 would be 123, which is greater than 1. If the exponent is negative, the answer will most likely be less than 1. For example, 1.23 to the power or -2 would be .0123.
Hope this helps!
