Richard has just returned from his holiday in Bolandia. Before he left he exchanged $300 into
bols (Ъ). To make the exchange, a fixed amount of money (the commission) was taken off the
$300 and then the remaining money was exchanged for Ъ540. When he got back, Richard had
Ъ180 left, which he exchanged back into dollars. This time the Ъ180 was exchanged into dollars
first and then the commission was taken off, leaving Richard with $60. The commission charges
and exchange rates were the same at both exchanges.
If Richard had exchanged $500 at the start of his holiday, how many bols would he have
received?
A Ъ840
B Ъ900
C Ъ940
D Ъ1000

the correct answer is

c. 4

step-by-step explanation:

the given polynomial is

the degree of the polynomial is the highest exponent which is 4.

the -4 is called the leading coefficient.

this polynomial has only one term so it is a monomial.

the correct answer is option c.

75%

step-by-step explanation:

it has to have an angle of 90 degrees

answer: the sun

explanation:

water cycle describes the evaporation of water from earth's surface, formation of clouds and precipitation water back onto the surface of earth. seventy percent of the earth is covered with water in the form of seas and oceans. the heat of the sun causes the evaporation of water from the surface of the ocean. the water vapors rise and condense to form water droplets. the collection of these water droplets form clouds which rain down again.

the evaporation of the oceans surface water as part of the water cycle is caused by the sun
