Answer:

2^{32} is the answer.

Step-by-step explanation:

If we put a penny on the first square of a chess board, 2 on second, six on third and we keep on doing double for the next square then it will form a geometric sequence in the form of T_{n}=2^{n-1}

1, 2, 4, 8, 16.........n terms

Now we have to calculate the pennies on square 33 that will be

So pennies on 33rd square will be

T_{33}=2^{33-1}=2^{32}

castortr0y [4]

Answer:

£29.37

Step-by-step explanation:

→ First step is to find the amount of hours it takes for 5 builders

\frac{3*\frac{11}{2} }{5} =\frac{33}{2} /5=\frac{33}{2} *\frac{1}{5} =\frac{33}{10} =3\frac{3}{10}

→ Now we know how long 5 builder takes we need to multiply the hourly rate by their time worked

3\frac{3}{10} *8.90=\frac{33}{10} *8.90=3.3*8.90 = 29.37

A builder was building a fence. In the morning, he worked for 2/5 of an hour. In the afternoon, he worked for 9/10 of an hour. H
Bas_tet [7]

Hey there! I'm happy to help!

We want to see how many times bigger 2/5 is than 9/10. Let's call how much bigger 2/5 is b and solve below.

9/10b=2/5   (2/5 is b times larger than 9/10)

We divide both sides by 9/10, so your division would be 2/5÷9/10.

b=4/9

Therefore, the builder worked 4/9 times as long in the morning as he did in the afternoon.

Have a wonderful day! :D
