A number n plus 7 is less than or equal to 9

1 answer:

7 0

N ≤ 2, if n plus 7 is less than or equal to 9 (n+7 ≤ 9) then carry the 7 over to create n ≤ 9-7 giving the answer n ≤ 2 (n less than or equal to 2)

What single decimal multiplier would you use to decrease by 13% followed by a 6% decrease?

spayn [35]

Answer:

0.8178

Step-by-step explanation:

To make a 13% decrease in a value, we need to make the difference between the value (X) and 13% of the value:

X - 13% of X = X - 0.13*X = 0.87*X

To make a 6% decrease, following the same method, we just need to multiply the value by (1-0.06) = 0.94

So, to represent in a single decimal value a decrease of 13% and then a decrease of 6%, we just need to multiply the value by 0.87 and then by 0.94:

X*0.87*0.94 = X*0.8178

So the single decimal multiplier is 0.8178

Answer:

$3,813.33 \: {cm}^{3}$

Step-by-step explanation:

Volume of the space that is not occupied = Volume of cube shaped box - volume of soccer ball

$= {20}^{3} - \frac{4}{3} \times 3.14 \times {10}^{3} \\ \\ = 8000 - \frac{4}{3} \times 3.14 \times 1000 \\ \\ = 8000 - \frac{4}{3} \times 3140 \\ \\ = 8000 - \frac{12560}{3} \\ \\ = 8000 - 4,186.66667 \\ \\ = 3,813.33333 \\ \\ = 3,813.33 \: {cm}^{3}$
