Answer with Step-by-step explanation:

The perimeter(P) of a semi circle is given by:

P=πr+2r

where r is the radius of the semicircle

r=d/2 where d is the diameter

We are given diameter=12 cm

⇒ Radius= 12/2

               = 6 cm

Perimeter=3.14×6+2×6

               =18.84+12

              =30.84 cm

Hence, best approximation for the perimeter of a semicircle with a diameter of 12 cm is:

30.84 cm

solmaris [256]

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

The ratio (by volume) of salt and sugar in a certain mixture is 4 to 8. If the total volume of the solution is 300 cubic feet, w
Tatiana [17]
You will use the ratio 4:8 to create a part to part to whole ratio.

First simplify 4:8 to 1:2, then make it 1:2:3 (Salt:Sugar:Total).

Use this to find the volume of sugar.  2 sugars for every 3 total would be equivalent to 200 cubic feet of sugar for every 300 total cubic feet.

Tim poured 0.5 liters of water into a beaker and then added 300 milliliters more. What was the total amount of water in the beak
SVETLANKA909090 [29]
So, Using your conversion chart(if you have one) you'd see 1 liter makes 1000 milliliters. So, if you have half of a liter(0.5), then you have 500 milliliters. If he adds 300 more, then you get 800 milliliters total, which is also equal to 0.8 liters. Hope this helps!
