Answer:

5 Months and Tina's saving after 5 months from either of the given options would be $250

Step-by-step explanation:

Option 1

Tina saves $200 away initially and save $10 every month

Let Tina save for X month, then her total saving after X month would be =  

$200 + $10X

Option 2

Tina saves $100 away initially and save $30 every month

Let Tina save for X month, then her total saving after X month would be =  

$100 + $30X

The savings from two options must be equal at the end of X months.  

$200 + $10X = $100 + $30X

$200 - $100 = $30X - $10X

$100 = $20X

X = $100/$20  

= 5

So Tina will save equal amount from both the options if she saves for 5 months.  

Her saving after 5 months through both the options  

Option 1 : $200 + $10X = $200 + $10 x 5 = $250

Option 2 : $100 + $30X = $100 + $30 x 5 = $250

The <em>correct answers</em> are:


It would take 5 months and she would save $250.


Explanation:


Let m be the number of months.


For the first way of saving, $200 up front and $10 each month, the expression would be

200+10m.


For the second way of saving, $100 up front and $30 each month, the expression would be

100+30m.


Setting them equal gives us the equation

200+10m = 100+30m


Subtract 10m from each side:

200+10m-10m = 100+30m-10m

200 = 100+20m


Subtract 100 from each side:

200-100 = 100+20m-100

100 = 20m


Divide both sides by 20:

100/20 = 20m/20

5 = m


It would take 5 months.


$200 up front and $10 each month for 5 months:

200+10m

200+10(5)

200+50

250


She would save $250.

gregori [183]

Answer:

7.4825 km or 7.48 km (rounded to nearest hundredth)

Step-by-step explanation:

<u>Ranch's measurements rounded up to the nearest hundredth:</u>

1st measurement = \sqrt{60} = 7.75 km

2nd measurement = \frac{58}{8} = 7.25 km

3rd measurement = 7.3(recurring) = 7.33 km

4th measurement = 7\frac{3}{5} = 7.60

<u>The average of the four measurements is:</u>

(7.75 + 7.25 + 7.33 + 7.60) ÷ 4 = 7.4825 km or 7.48 km (rounded to nearest hundredth)

Question 5
navik [9.2K]

Answer:

A. Similar using SAS; ∆ABC ~ ∆DFE

Step-by-step explanation:

m<B of ∆ABC = m<F of ∆DFE

AB corresponds to DF

AB/DF = 12/8 = 3/2

BC corresponds to FE

BC/FE = 24/16 = 3/2

Thus, the ratio of the corresponding sides of both triangles are the same. Therefore, both triangles has two sides that are proportional to each other, and also had an included corresponding angles that are congruent to each other.

By the SAS criterion, we can conclude that both triangles are similar to each other. That is, ∆ABC ~ ∆DFE
