Probably 2 because It doesn't matter how many beads are in the bag and for 33.34% you would probably draw 2 beads before on the third draw getting a red one and 30% is close to 33.34% then I would you would probably draw 2 beads before drawing a red one.

3000 per month for 40 years plus 5% equals how much money
Sveta_85 [38]

I hope you do not intend some sort of compounding.

Basically, 3000 per month for 40 years can be calculated by doing some simple maths. So 3000 x 12 to get for a complete year. Which is 36000. NOw we can multiply this value by 40 to get the correct amount. So that is 1440000.

Now five percent of this amount is 5 / 100 x 1440000 = 72000. So the final answer after adding 5 % would be 1512000.

Use the scale of 1cm=45 km
alex41 [277]

Answer:

d = 7.4 cm is the distance between the two cities on the map.

Step-by-step explanation:

Let d = the distance measured on the map in centimeters (cm) between any two locations and let D be the actual distance in kilometers (km) between these same two locations.

Since the scale on the map is 1 cm = 45 km, then the ratio of the distance on the map to the actual distance is equal to 1cm/45 km; therefore the quotient of any measured distance d on the map divided by the corresponding much longer actual distance D would have to maintain (equal) this same ratio; In other words, we can set up the following proportion to solve for d given the actual distance D = 333 km as follows:

1 cm/45 km = d/D

Substituting, we get:

1 cm/45 km = d/333 km

d/333 km = 1 cm/45 km

(d/333 km)(333 km) = (1 cm/45 km)(333 km)

d = (333 km/45 km)(1 cm)

d = 7.4 cm is the distance between the two cities on the map.

Check:

1 cm/45 cm = d/333 km

1 cm/45 cm = 7.4 cm/333 km

1 cm/45 cm = 1 cm/45 km (Therefore, the distance ratio of the map has been maintained
