David and Amanda are trying to figure out how long they can live off their $12,350 savings if they spend $240 each month. They h

ave each created an equation. David’s Equation Amanda’s Equation y = 12,350 – (240x) y = 12,350 + (240x) Which person has the correct equation to model this linear relationship? Amanda’s equation is correct, because their spending will be multiplied by the number of months and then added to their savings. Amanda’s equation is incorrect, because their spending will increase the amount of their savings. David’s equation is correct, because their spending will be multiplied by the number of months and then subtracted from their savings. David’s equation is incorrect, because their spending should be a fixed amount and should not be multiplied.

David's : y = 12,350 - (240x)
Amanda's : y = 12,350 + (240x)

Answer:

David's equation y=12350-240x is correct  to model this linear relationship.

Step-by-step explanation:

David and Amanda have total savings money =$12350

If they spend money in each month =$240

Equation created by David

y=12350-240x

Equation created by Amanda

y=12350+240x

Amanda's equation is incorrect becuase their spending money multiplied by the number months and then added to their savings and increase the amount of their savings.

But in David's eqaution  spending money multiply by the number of months and then subtracted from their savings .Therefore, it decrease the amount of saving money.

Hence, David's equation is correct ,because their spending money multiplied by the number of months and then subtracted from their saving money.

Imagine a new pasture with grass growing on it. Every day after the seeds have germinated, the number of blades of grass in the
Arisa [49]

Answer:

It took 17 days for the pasture to be one-third covered in grass

Step-by-step explanation:

* Lets explain how to solve the problem

- The number of blades of grass is triple every day

- Consider that there are x blades in the first day

∵ The number of blades of grass is triple every day

∴ The next day the number of blades of grass will be 3x

∴ The formula to find the number of blades of grass after d days is

   x(3)^{d}

- After 18 days, the entire pasture is completely covered in grass

∵ d = 18

∴ The number of blades of grass = x(3)^{18}

- We need to know the the number of days that took for the pasture

  to be one-third covered in grass

∵ The number of blades of grass for 1/3 covered = (\frac{1}{3})x(3)^{18}

∴ (\frac{1}{3})x(3)^{18}=x(3)^{d}

- Remember  \frac{1}{3}=3^{-1}

∴ 3^{-1}x(3)^{18}=x(3)^{d}

- Remember we add the power of the same bases when we

 multiply them

∴ x(3)^{-1+18}=x(3)^{d} ⇒ divide both sides by x

∴ (3)^{17}=(3)^{d}

- Remember if the two bases equal in the equation, then their

 powers are equal

∴ d = 17

* It took 17 days for the pasture to be one-third covered in grass

What is the quotient of 1.728 x 109 and 4.8 x 106 expressed in scientific notation?​
fenix001 [56]

Step-by-step explanation:

\to 1,728 \times {10}^{9}

= 1,728 \times {10}^{9}

= 1,728 \times 1.000.000.000

= 1.728.000.000

1,728 \times {10}^{9} = 1.728.000.000

\:

\to 4,8 \times {10}^{6}

= 4,8 \times {10}^{6}

= 4,8 \times 1.000.000

= 4.800.000

4,8 \times {10}^{6} = 4.800.000

the side length of the state flag of Colorado are in the ratio of 2:3 if the flag is 12 ft long what is the height?​
yanalaym [24]

Answer:

The height is 8

Step-by-step explanation:

Ratios are just fractions. That being said, you also have part of a fraction. You know that the colorado flag is in 2:3, and 12 feet long is according to that ratio; it equals each other.

Make the equation.

\frac{2}{3}  = \frac{x}{12}

Now isolate x (in order to solve for it)

12 * \frac{2}{3}  = \frac{x}{12}*12\\8 = x

x= 8

The height is 8.

8/12 = 2/3 ✅

Logs are stacked in a pile. The bottom row has 50 logs and next to bottom row has 49 logs. Each row has one less log than the ro
Mars2501 [29]

Answer:

46 logs on the 5th row.

Step-by-step explanation:

Number of logs on the nth row is

n =  50 - (n-1)

 n = 51 - n    (so on the first row we have  51 - 1 = 50 logs).

So on the 5th row we have 51 - 5 = 46 logs.
