First find the area of two sides (Length*Height)*2 sides, 70. Then find the area of adjacent sides (Width*Height)*2 sides, 60.9. And then find the area of ends (Length*Width)*2 ends, 87. Lastly add the three areas together to find the surface area, 217.9.

daser333 [38]

Answer:

6,750,000 cm³ = 6.75 m³

Step-by-step explanation:

a scale version means that the ratio of every dimension of scale vs. real object is 1/50.

volume is created by multiplying 3 dimensions.

so, going from scaling to real the volume has to be multiplied by 50×50×50 = 50³ = 125000

so, as for the scale model we needed 54 cm³, for the full size object we need 54×125000 = 6,750,000 cm³ of metal.

or to bring it to m³ (1m³ = 100×100×100 cm = 1000000 cm³)

that would be 6.75 m³ of metal.

Yolanda had 47 customers on Saturday from 6 to 7 pm. Then on Monday she only had 20 customers from 5pm to 6pm. Question: Let’s find how much percentage rate did Yolanda’s customer’s decreased over time. Solution => Saturday = 47 customers. => Monday = 20 customer. Let’s start solcing => 47 – 20 = 27 There are 27 customer that were lost over time. => 27 / 47 = 0.57 * 100 = 57% Let’s try checking our answer: => 47 * .57 = 26.79 or round off to 27, since we rounded off also our percentage.

He is paid a commission of 9 percent of his first $6,000 in sales during the month and 14 percent on all sales over $6,000. What

Agata [3.3K]

Answer:

$1,956.80

Step-by-step explanation:

For amounts over $6000, the commission can be computed as ...

0.14s -300 . . . . . . for sales (s) ≥ 6000

So, for $16,120 in sales, the commission is ...

0.14×$16,120 -300 = $2,256.80 -300 = $1,956.80

The commission schedule suggests that for larger amounts, you divide the problem into two parts: calculate the commission on $6000, and separately calculate the commission on the amount over $6000.

0.14(s -6000) + 0.09(6000)

= 0.14s - 0.14·6000 +0.09·6000

= 0.14s -300 . . . . the formula used above for s ≥ 6000
