So if the bank was 2/3 full, and then after the pennies are removed it is 1/2 full, then the volume taken up by those removed pennies is the difference:
(2/3)-(1/2)=(4/6)-(3/6)=1/6

If there are 120 pennies in 1/6 of the bank's volume, then the total can be found by multiplying 120 by 6 (so that (1/6)*6=1 (the total volume))

120*6=720
You can fit 720 pennies in that bank

Can somebody please help me out:))

Answer:

50ft

Step-by-step explanation:

Hi,

Considering that one side is equal to 38 degrees, we know this isn't a 30 - 60 - 90 triangle.

One of the legs is equal to 40 feet

So, tan(b) = 40/x

tan(38 degrees) is 0.78 round up to 0.8 (if that's what your teacher wants)

0.8 = 40/x

0.8x = 40

x = 50ft

I hope this helps

Pls help thank you. Find the value of the expression use estimation to check your answer ​
RoseWind [281]

Answer:

2.) 2703

4.) 9

Step-by-step explanation:

2.)

5327 - 2624 = ?

We subtract from left to right to get;

(7 - 4 = 3) then (2 - 2 = 0) then carrying  1 from 5, (13 - 6 = 7) and (4 - 2 = 2)

So writing the answer;

2 then 7 then 0 then 3

i.e Answer = 2703

4.)

648 ÷ 72 = ?

72 × 10 = 720

So we must multiply 72 by a number less than 10 since 720 > 648

We should look for a number such that 2 in 72 times the number should give an answer with 8 in the end.

Such a number can be 9;

Manually multiplying 72 and 9 we get 648 and we are right!
