Bo has $500 in his savings account. He plans to add $150 to his savings account every month. Recently, he purchased a tractor to
MariettaO [177]

Answer:

A. $2,000

Step-by-step explanation:

<em>Assuming that the money in the savings account will be used to pay off for tractor.</em>

<em>let the number of months be m</em>

Savings after m months will be 500+ 150m

After m months the installments paid  will 200m

To find the months it will take to pay for the tractor in m months, savings and the installments will be the price of the tractor. As an equation it be represented as below:

500+150m +200m = 4000

150m + 200m = 4000-500  <em>(grouping like terms)</em>

350m = 3500  <em>(Making m the subject of the formula)</em>

350m/350  = 3500/350

m = 10

Substituting m into the equation of saving after m months

<em>Savings after m months will be</em> 500+ 150m

<em>Savings after m months will be</em> 500 + 150(10)

<em>Savings after m months will be</em> 500 + 1500

Savings after m months will be $2000

Use a proportion with sides AB and RS to find the scale factor of ABD to RST.
Dmitry_Shevchenko [17]

Answer:

\boxed{3:1}

Step-by-step explanation:

Similar triangles are those whose shape is the same, but they don't necessarily have the same size. However, the corresponding sides of the triangles are in the same length ratio. In this exercise, we know all the sides of triangle ΔABC and an only side of the triangle ΔRST. To find the scale factor, we must compute the following:

\frac{AB}{RS}=\frac{18}{6}=3 \\ \\ Scale \ factor \\ \boxed{3:1}

Finally, the other sides of the tingle ΔRST can be found by dividing each side of triangle ΔABC by 3 as follows:

ST=\frac{15}{3}=5 \\ \\ RT=\frac{9}{3}=3
