Pablo spit 3/4 pounds of candy amping 4 people what is the unit rate in pounds per person

Sunny_sXe [5.5K]

The unit rate is $\frac{3}{16}$ pounds per person.

Step-by-step explanation:

Given,

Quantity of candy Pablo have = $\frac{3}{4}$ pounds

Number of people = 4

We will divide the Quantity of candy by number of people.

Quantity of candy per person = $\frac{3}{4}*\frac{1}{4}$

Quantity of candy per person = $\frac{3}{16}$ pounds of candy

The unit rate is $\frac{3}{16}$ pounds per person.

For the graphed exponential equation, calculate the average rate of change from x = −3 to x = 0.

iragen [17]

Answer:

$-\frac{7}{3}$

Step-by-step explanation:

To solve this, we are using the average rate of change formula:

$m=\frac{f(b)-f(a)}{b-a}$

where

$m$ is the average rate of change

$a$ is the first point

$b$ is the second point

$f(a)$ is the function evaluated at the first point

$f(b)$ is the function evaluated at the second point

We want to know the average rate of change of the function $f(x)=0.5^x-6$ form x = -3 to x = 0, so our first point is -3 and our second point is 0. In other words, $a=-3$ and $b=0$ .

Replacing values

$m=\frac{f(b)-f(a)}{b-a}$

$m=\frac{0.5^0-6-(0.5^{-3}-6)}{0-(-3)}$

$m=\frac{1-6-(8-6)}{3}$

$m=\frac{-5-(2)}{3}$

$m=\frac{-5-2}{3}$

$m=\frac{-7}{3}$

$m=-\frac{7}{3}$

We can conclude that the average rate of change of the exponential equation form x = -3 to x = 0 is $-\frac{7}{3}$

Samuel can type nearly 40 words per minute. Use this information to find the number of hours it would take him to type 3.2 × 105

Oliga [24]

The hours it would take to type 3.2 x 10^5 words is 1.33 x 10^2 hours.

<h3>How many hours would it take to type 3.2 x 10^5 words?</h3>

Standard form is used in expressing large numbers in smaller numbers. It is used to transform large numbers into smaller number.

In order to write a number in standard form, the number is written as a decimal number, between 1 and 10 and multiplied by a power of 10.

For example: 1 x 10² is equivalent to 100

The first step is to determine how many words he can type in 1 hour : 40 x 60 = 2400 words = 2.4 x 10³

The second step is to divide 3.2 x 10^5 words by 2.4 x 10³

3.2 x 10^5 ÷ 2.4 x 10³ = 1.33 x 10^(5 - 3)

1.33 x 10^2 hours
