Answer: 3x10=30
3x10(with the power of 2)=300
3x10(with the power of 3)=3000
3x10(witht the power of 4)=3000
Step-by-step explanation:
sorry if this dont help
All we need to do is to find out how much is worth one yard in both fabrics, so we divide $15.00 by 2 and $37.50 by 5:
$15.00 ÷ 2 = $7.50 per yard
$37.50 ÷ 5 = $7.50 per yard
As both prices per yard are the same, the answer is: <u>Yes, these fabrics have the same unit cost.</u>
Answer:
The value of x is 2.
Step-by-step explanation:
First, you have to make the left side into 1 fraction by making the denorminator the same :




Then you have to do cross multiplication :












You can factor the 32 out of the sum:

We can also change the index as follows

Now, we have a theorem that states that the series

converges if and only if
, and in this case we have

This is your case, because you have

which implies that your series converges, and the value is

Step-by-step explanation:
(72)¹⁴³ ≡ x (mod 7)
Since 72 ≡ 2 (mod 7),
72³ ≡ 2³ (mod 7) ≡ 1 (mod 7).
Therefore (72)¹⁴³ = (72³)⁴⁷ * (72²)
≡ 1⁴⁷ * 4 (mod 7) ≡ 4 (mod 7).
The answer is A.
