Working 6 days, a worker earned<br> 150000 LL<br> a) How much will he earn by working 21<br> days?
Mila [183]

Answer:

525,000 LL

Step-by-step explanation:

6 x 3 = 18 (days)

150,000 x 3 = 450,000

21 - 18 = 3 so 6 * 2 = 3 ( 150,000 *(divide)  2 = 75,000)

so 450,000 + 75,000 = 525,000

Gemiola [76]

Answer:

Perimeter of polygon B = 80 units

Step-by-step explanation:

Since both polygons are similar, their corresponding sides and perimeters are proportional. Knowing this we can setup a proportion to find the perimeter of polygon B.

\frac{side-polygonA}{side-polygonB} =\frac{perimeter-polygonA}{perimeter-polygonB}

Let x be the perimeter of polygon B. We know from our problem that the side of polygon A is 24, the side of polygon B is 15, and the perimeter of polygon A is 128.

Let's replace those value sin our proportion and solve for x:

\frac{side-polygonA}{side-polygonB} =\frac{perimeter-polygonA}{perimeter-polygonB}

\frac{24}{15} =\frac{128}{x}

x=\frac{128*15}{24}

x=\frac{1920}{24}

x=80

We can conclude that the perimeter of polygon B is 80 units.
