Answer:
30 × 8.8 = 30 × (8 + 0.8) = 240 + 24 = 264
Step-by-step explanation:
I want to buy 30 calculators that cost $ 8.80 each.
So, to calculate the total price, we have to multiply 8.8 with 30.
Now, we have to calculate this multiplication mentally.
To do this, we can write the multiplication as 30(8 + 0.8).
So, we can separately multiply 30 with 8 and calculate it mentally to be 240 and then multiply 30 with 0.8 and calculate it mentally to be 24 and finally add the two products.
Therefore, 30 × 8.8 = 240 + 24 = 264 (Answer)
Answer:
x=3
Step-by-step explanation:
(-11)^x * (-11) ^4 = (-11)^10/ (-11)^3
We know a^b * a^c = a^(b+c)
(-11)^(x +4) = (-11)^10/ (-11)^3
We know a^b / a^c = a^(b-c)
(-11)^(x +4) = (-11)^(10 -3)
(-11)^(x +4) = (-11)^(7)
The bases are the same so the exponents are the same
x+4 = 7
Subtract 4 from each side
x+4-4 = 7-4
x =3
Answer:
The correct answer is 6000
Step-by-step explanation:
I disagree because 10 to the 3rd power = 1000 x 6 = 6000
The mistake he made was that George multiplied all of the number so, 6 x 10 x 3 = 60 x 3 = 180.
