Answer:

  d.  May

Step-by-step explanation:

Working through the chain, we have ...

  Feb = 1.10×Jan

  Mar = 0.85×Feb = 0.935×Jan

  Apr = 1.20×Mar = 1.122×Jan

  May = 0.90×Apr = 1.0098×Jan

  Jun = 1.05×May = 1.06029×Jan

The multiplier that is closest to 1 is 1.0098, so May has sales closest to January.

_____

The percentage increase or decrease can be converted to a multiplier by adding it to 1. If p% is the percentage change, then adding it to an original value looks like ...

  original + p% × original = original × (1 +p%) . . . . . . . distributive property

And p% translates to a decimal number by replacing % with /100 or ×0.01.

  10% increase:   original × (1 + 10/100) = original × 1.10

  15% decrease:   original × (1 - 15/100) = original × 0.85

I need to know what to do

1) First, you would need to create an equation for this problem. Let x represent the unknown percentage.
\frac{35}{185} = \frac{x}{100}

Next, you would cross multiply. 
185x = 3,500

Now, all you would have to do is isolate the x. To do this, you would divide both sides by 185. 
x = <span>18.918%

Your answer was correct!

2) </span>First, you would need to create an equation for this problem. Let x represent the unknown 85%. 
\frac{x}{190}<span> = </span>\frac{85}{100}<span>

</span>Next, you would cross multiply. 
100x = 16150<span>

</span>Now, all you would have to do is isolate the x. To do this, you would divide both sides by 100. 
x = 161.5

3) First, you would need to create an equation for this problem. Let x represent the unknown percentage.
\frac{24}{128} = \frac{x}{100}

Next, you would cross multiply. 
128x = 2,400

Now, all you would have to do is isolate the x. To do this, you would divide both sides by 128. 
x = 18.75%


I hope this helps!

HELP±! FAST<br><br>What is the scale factor?
cupoosta [38]

Answer:

\frac{5}{3}

Step-by-step explanation:

Given that the triangles are similar then the ratios of corresponding sides are equal.

To determine the scale factor calculate the ratio of corresponding sides, that is

\frac{NO}{GH} = \frac{15}{9} = \frac{5}{3}
