It would be 6 because 21 is 3 times as much to 7 so 2 times 3 is 6<span />

Answer:

776644 rounds to 777000

Step-by-step explanation:

hundred thousand ten thousand thousand hundred tens ones

7 7 6 6 4 4

We are rounding to the nearest thousand so we are rounding the first 6. We need to look at the next 6 (the one in the hundreds place) 6>=5 so we will round the 6 in the thousands place up to 7

On the way home from her friend's house Sandy skateboards 30% of the way, walks 1/2 of the way, and then skips the rest of the w

netineya [11]

Answer:

0.2

Step-by-step explanation:

Convert the walking to percent

$\frac{1}{2} \times 100 = 50$

Add both skateboarding and walking

$30\% + 50\%\\\\= 30 + 50\\\\= 80$

Now, subtract that from a whole percent

$100 - 80 = 20\\\\20\%$

Convert it to a decimal

$20\% = \frac{20}{100} \\\\=20 \div 100\\\\= 0.2$

Therefore, in decimal, 0.2 is the number that shows the portion of the distance Sandy skips.
