0.75-0.5= 0.25 kilograms

3.006 rounded to the nearest tenth

Ann [662]

3.006 rounded to the nearest tenth is 3.0. This is due to the fact that the 6 rounded up will mean that the current 0 becomes 1, but this will not be carried to the tenth when rounding up.

After 1 year, $800 deposited in a savings account with simple interest had earned $64 in

stepan [7]

Answer:

8%

Step-by-step explanation:

We will use the equation provided to solve this problem.

$I=Prt$

Lets plug in the values:

$64=800x(1)$ First, divide both sides by 800.

$.08=x(1)$ Multiply x by 1

$x = .08$

Now, we multiply .08 by 100 to get our interest rate:

(.08)100 = 8

The interest rate is 8%

Suppose that you drop a ball from a window 50 metres above the ground. The ball bounces to 50% of its previous height with each

stich3 [128]

We have been given that you drop a ball from a window 50 metres above the ground. The ball bounces to 50% of its previous height with each bounce. We are asked to find the total distance traveled by up and down from the time it was dropped from the window until the 25th bounce.

We will use sum of geometric sequence formula to solve our given problem.

$S_n=\frac{a\cdot(1-r^n)}{1-r}$ , where,

a = First term of sequence,

r = Common ratio,

n = Number of terms.

For our given problem $a=50$ , $r=50\%=\frac{50}{100}=0.5$ and $n=25$ .

$S_{25}=\frac{50\cdot(1-(0.5)^{25})}{1-0.5}$

$S_{25}=\frac{50\cdot(1-0.0000000298023224)}{0.5}$

$S_{25}=\frac{50\cdot(0.9999999701976776)}{0.5}$

$S_{25}=100\cdot(0.9999999701976776)$

$S_{25}=99.99999701976776\approx 100$

Therefore, the ball will travel 100 meters and option B is the correct choice.
