Answer:

26 inches

Step-by-step explanation:

To the nearest inch, the diameter of the tire is 26 inches.

The bike traveled 136 feet in 20 revolutions. First we want to convert this to inches.

136 ft * 12 in/ft = 1632 inches.

Next we find how many inches it travels in 1 revolution:

1632/20 = 81.6 inches

The distance around the tire is called the circumference, and the formula for circumference is

C=πd

Our circumference is 81.6 and π is 3.14:

81.6 = 3.14d

Divide both sides by 3.14:

81.6/3.14 = 3.14d/3.14

26 = d

Hope this helped!!!!

0.9(x+1.4)-2.3+0.1x=1.6

First, distribute 0.9 to x and 1.4 to get rid of the parentheses.

0.9x+1.26-2.3+0.1x=1.6

Now, combine like terms to simplify the equation a bit.

x-1.04=1.6

Add 1.04 to both sides:

x=2.64

Your answer is 2.64.

I hope this helps :)

In a fruit punch drink, the 3 ingredients are apple juice, orange juice and cranberry juice. If 3/4 of the drink is apple juice

SVETLANKA909090 [29]

Step-by-step explanation:

Let's assume x = apple juice, y = orange juice, and z = cranberry juice

$1 = x + y + z \\ 1 = \frac{3}{4} + \frac{1}{10} + z \\ z = 1 - \frac{3}{4} - \frac{1}{10} \\ z = \frac{3}{20}$

<u>x : y : z = 3/4 : 1/10 : 3/20</u>

If we were to make them all in the same denominator, x : y : z = 15/20 : 2/20 : 3/20.

$\frac{3}{4} \times \frac{5}{5} = \frac{15}{20} \\ \\ \frac{1}{10} \times \frac{2}{2} = \frac{2}{20}$
