The given expression is

$\frac{1}{2}(6e -3f - \frac{3}{4} )$

TO find the equivalent expression, we use distributive property

Distributing half on 6e -3f -3/4, we will get

$= \frac{1}{2} * 6e - \frac{1}{2} * 3f - \frac{1}{2} * \frac{3}{4} \\ =3e - \frac{3f}{2} - \frac{3}{8}$

And that's the required equivalent expression of the given expression .

Complete the equation that represents the total value of the nickels and p pennies

Answer:

Answers below

Step-by-step explanation:

Equation

Let's call:

p = number of pennies Janesa has in her pocket

n = number of nickels Janesa has in her pocket

She has 24 coins in total, thus:

$p + n=24\qquad\qquad [1]$

Since each penny is worth $0.01 and each nickel is worth $0.05, and Janesa has $1 in total:

$0.01p+0.05n=1$

Multiplying by 100:

$p+5n=100\qquad\qquad [2]$

A. Completing the equation:

$5n+p=100$

From [1]:

$p=24-n$

Substituting into [2]:

$24-n+5n=100$

Simplifying:

$24+4n=100$

Rearranging:

$4n=100-24=76$

$n=76 / 4= 19$

$p=24-19=5$

B. There are 5 pennies in Janesa's pocket

C. Since each penny is worth $0.01, the total value of pennies is 5*$0.01=$0.05

The total value of the pennies is $0.05

D. The total value of the nickels is 19*$0.05 = $0.95

E. Jackson should say she has 19 nickels and 5 pennies

A Ferris wheel is 35 meters in diameter and boarded from a platform that is 3 meters above the ground. The six o'clock position

Umnica [9.8K]

Answer:

height = 20.5068 m

Step-by-step explanation:

Given the data in the question;

First, lets calculate the amplitude, midline and period of 8minutes

Amplitude = 35 / 2 = 17.5

|A| = 17.5

A = - 17.5 { since the wheel starts at 6 o clock }
