Use integers to represent the values in the statement.
Svetradugi [14.3K]

Answer:

Highest Elevation: 14240

Lowest Elevation: -285

Step-by-step explanation:

Given

Highest\ Elevation = 14,240\ ft above sea level

Lowest\ Elevation = 285\ ft below sea level

Required

Represent both altitudes as an integer

For the Mountain:

Take the sea level as 0 feet

Altitude = Highest\ Elevation - Sea\ Level

Altitude = 14240 - 0

Altitude = 14240

Hence, the integer is 14240

For the Valley:

Take the sea level as 0 feet

Altitude = Sea\ Level - Lowest\ Elevation

Altitude = 0 - 285

Altitude = -285

Hence, the integer is -285

George wants to invest $20,000 One investment pays interest at a rate of 18 2/3% while another pays interest at a rate of 0.1872
xz_007 [3.2K]

Answer:

Investment with interest rate 0.1872 is better

Step-by-step explanation:

Given as :

George investment principal = $20,000

The Rate of interest  (R1)   = 18 \frac{2}{3} % = \frac{56}{3} %

I.e   R1 = 18.67 %

Again The The Rate of interest  (R2)  = 0.1872  = 18.72 %

Let the time period for both rate of interest = 1 years

Now from compound interest method

Amount = Principal × (1 + \frac{Rate}{100})^{Time}

Or,    A 1 = $ 20 , 000 × (1 + \frac{18.67}{100})^{1}

Or,    A 1 = $ 20 ,000 × 1.1867

∴       A 1 = $ 23,734

And   A 2 = $ 20 , 000 × (1 + \frac{18.72}{100})^{1}

Or,     A 2 = $ 20 ,000 × 1.1872

∴        A 2 = $ 23,744

Hence From the calculation of both amount it is clear that , investment with interest rate 0.1872 is better . Answer

Need help ASAP thank you
Sergeu [11.5K]

Answer:

x = 14

Step-by-step explanation:

First put it into slope intercept form

20 = 2x - 8

Move the variable to the left hand side and change its symbol

-2x + 20 = -8

Move the constant to the right hand side and change its symbol

-2x = -8 - 20

Calculate the difference

-2x = -28

Divide both sides of the equation by -2

x = 14

Solution

X = 14
