Step-by-step explanation:

Multiply the amount of feet in one mile by the amount of miles in the question(5,280 x 50 = 264,000)

Divide the amount of feet in 50 miles by the amount of minutes in 1 hour to get the amount of feet per mile (264,000 ÷ 60 = 4,400)

Divide the amount of feet per mile to get by the amount of seconds in a minute to get the amount of feet per second (4,400 ÷ 60 = 73.33)

Your answer rounded to the nearest whole number is 73

12 + x to the power of 4 - 6 when x = 8

iren [92.7K]

value of $12+x^4-6$ at x=8 is $5002$ .

<u>Step-by-step explanation:</u>

here we need to evaluate 12 + x to the power of 4 - 6 when x = 8 or , $12+x^4-6$ where x=8 . Let's find out:

⇒ $12+x^4-6$

Putting x =8 :

⇒ $12+8^4-6$

Splitting 8 to power 4 into 8 to power 2 ( 2 times )

⇒ $12+8^2(8^2)-6$

⇒ $12+64(64)-6$

⇒ $12+4096-6$

⇒ $4096+6$

⇒ $5002$

Therefore , value of $12+x^4-6$ at x=8 is $5002$ .

There are 10 marbles in a bag. 1/5 are red and the others are blue. What is the ratio to blue marbles.

Irina-Kira [14]

Answer:

Ratio = 1 : 4

Step-by-step explanation:

Total marbles = 10

Given 1/5 is red, that is 1/5 of the total marbles are red

$\frac{1}{5} \ of \ 10 = \frac{1}{5} \times 10 = 2$

Therefore , 10 - 2 = 8 marbles are blue.

Ratio of red marbles to blue marbles

$\frac{2}{8} = \frac{1}{4} = 1 : 4$
