Answer:

7\times 200+7\times 50+7\times 6

Step-by-step explanation:

We are asked to write an expression that shows the multiplication of 7\times 256 using expanded form and the distributive property.

First of all, we will write 256 in expanded form as:

256=200+50+6

Now, we will multiply 7 by (200+50+6) as:

7\times (200+50+6)

7\times 200+7\times 50+7\times 6

Therefore, our required expression would be 7\times 200+7\times 50+7\times 6.

A roll of paper towels is wound around a hollow cardboard tube. the
blsea [12.9K]

The radius of the cardboard tube of 85th loop of paper is 4.92cm

The arithmetic sequence is the sequence where every term is increased or decreased by a fixed number from the previous number.

Here the outer radius of the tube is 2.4 cm

the thickness of the paper is 0.3mm= 0.03cm

i.e. in every loop the increase in the radius of the loop is 0.03cm

then the radius in every sequence will be  2.40, 2.43, 2.46, 2.49, 2.52, .....

so here it is clear that it is an arithmetic sequence with a common difference of 0.03.

nth term of the sequence, aₙ = a₁ + (n - 1)d where a₁ is the first term, n is the index of the loop, and d is a common difference.

here a₁ =2.40

d=0.03

n=85

the radius of tube of the 85th loop will be= r= 2.40+(85-1)0.03= 2.40+ 2.52= 4.92

Therefore The radius of the cardboard tube of the 85th loop of paper is 4.92cm

Can someone help me?​
Ratling [72]

Answer:

135 ft²

Step-by-step explanation:

Heres a cool little trick! if you cut off one side straight down, take for example the triangle to the right, and take it over to the left side, it makes a square! so then you just have to multiply 9 by 15! Hope This Helps! :P

A 150 ml bottle of shampoo cost $3.85. What is the cost of a 100 ml bottle of shampoo?
Advocard [28]
First of all, you need to calculate a 300ml bottle of shampoo, because it will be easier. 3.85 x 2=$7.70 Now you use $7.70 and divided by 3. 7.70/3 =$2.60 (rounded up).
Therefore, a 100ml bottle of shampoo costs $2.60.
