Answer:

0.64m squared

Step-by-step explanation:

Surface area is the area of the sides added together

I am going to assume that the bottom is a square

0.4 multiplied by 0.6 is 0.24

0.24 halved is 0.12

0.12 multiplied by 4 is 0.48

0.4 multiplied by 0.4 is 0.16

0.48 plus 0.16 is 0.64

Answer:

Step-by-step explanation:

Total Surface Area : Area (4 triangles) + Area (square)

4 x 1/2 x 0.4 x 0.6 + (0.4)²
2 x 0.24 + 0.16
0.48 + 0.16
<u>0.64 m²</u>

Answer:

511 employees

Step-by-step explanation:

Given data

P=690

rate= 2%

time = 13 years

let us apply the simple interest formula

A=P(1-rt)

Note the negative sign (since we are dealing with decrease)

A= 690(1-0.02*13)

A=690(1-0.26)

A=690*0.74

A=510.6

A= 511 approx

Hence the population will reduce to 511 employees

I'm having trouble with algebraic fractions . 3/2n-8/3=-29/12

nadezda [96]

what we can do is hmmmm get the LCD of all fractions, and multiply both sides by that LCD, let's see, we have denominators of 2, 3 and 12, so we can use the LCD of 12, and multiply both sides by 12 to do away with the denominators.

$\bf \cfrac{3}{2}n-\cfrac{8}{3}=-\cfrac{29}{12}\implies \stackrel{\textit{multiplying both sides by }\stackrel{LCD}{12}}{12\left( \cfrac{3}{2}n-\cfrac{8}{3} \right)=12\left( -\cfrac{29}{12} \right)}\implies (6)3n-(4)8=(1)-29 \\\\\\ 18n-32=-29\implies 18n=3\implies n=\cfrac{3}{18}\implies n=\cfrac{1}{6}$
