Answer:

g(x) = 0.8x gal/dollar

Step-by-step explanation:

This is a direct relation, each gallon costs 1.25, 20 gal. costs 25.00, etc.

f(x) = 1.25x where x = number of gal. f(x) is the cost

The inverse relation is the reciprocal,

for each $1.00, we can buy 1/1.25 = 0.8 gal.

g(x) = 0.8x where x = amount, g(x) is number of gallons

Find the missing length idicated.

irina1246 [14]

Answer:

x = 25.

Step-by-step explanation:

Since the longer side of the smallest triangle bisects the largest triangle's right angle, all three triangles shown are similar.

As seen in the diagram, the smaller triangle's hypotenuse (15) corresponds to the the largest triangle's hypotenuse (x), and the smaller triangle's shorter side length (9) corresponds to the largest triangle's shorter side length (15). So, we can set up a proportion...

$\frac{x}{15} =\frac{15}{9}$

9 * x = 15 * 15

9x = 225

x = 225/9

x = 25

Hope this helps!

2^-3 x 3^-2<br> 2 to the power of negative 3 times by 3 to the power of negative 2

Ivan

<h3>The value of 2 to the power of negative 3 times by 3 to the power of negative 2 is 0.013889</h3>

<em><u>Solution:</u></em>

<em><u>Given that:</u></em>

$2^{-3} \times 3^{-2}$

We have to find the value of expression

We know that,

$a^{-n} = \frac{1}{a^n}$

Therefore,

$2^{-3} \times 3^{-2} = \frac{1}{2^3} \times \frac{1}{3^2}$

We know that,

$a^2 = a \times a$

Similarly,

$2^{-3} \times 3^{-2} = \frac{1}{2 \times 2 \times 2} \times \frac{1}{3 \times 3}\\\\Simplify\\\\2^{-3} \times 3^{-2} = \frac{1}{8} \times \frac{1}{9}\\\\2^{-3} \times 3^{-2} = \frac{1}{72}\\\\Simplify\\\\2^{-3} \times 3^{-2} = 0.013889$

Thus value of 2 to the power of negative 3 times by 3 to the power of negative 2 is 0.013889

Connor is stuck in a traffic jam on a single-lane road. The traffic report tells him the

Debora [2.8K]

Answer:

Cornor should divide the total length of the road on which there is traffic by the length of each of the cars

Step-by-step explanation:

The best calculation he can use is to divide the total length of the road on which we have the traffic by the length of each of the cars

Mathematically, the best way to go about this is to convert the miles to feet then divide by the length of each of the cars

Mathematically 1 mile = 5280 feet

so 5.5 miles will be = 5280 * 5.5 = 29,040 feet

It is this length we shall now divide by 12.5 ft

And that is 29,040/12.5 = 2,323.2

Which is approximately 2,323 cars
