There are three kinds of rock: igneous, sedimentary, and metamorphic.
Igneous rocks form when molten rock (magma or lava) cools and solidifies. Sedimentary rocks originate when particles settle out of water or air, or by precipitation of minerals from water. They accumulate in layers. Metamorphic rocks result when existing rocks are changed by heat, pressure, or reactive fluids, such as hot, mineral-laden water. Most rocks are made of minerals containing silicon and oxygen, the most abundant elements in the Earth’s crust.
Answer:
The probability is 0.27
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
In this problem, we have that:
Odds of a win are 27 to 73.
This means that for 27+73 = 100 games, you are expected to win 27.
Desired outcomes
27 wins
Total outcomes
100 games
Probability of winning a game
Answer:
The answer is 118*
Step-by-step explanation:
90*+28*=118*
Supposing that the trail mix was 5/8 pound, and Lisa gave 1/8 pound, then to know what is left we only have to subtract those fractions:
5/8 - 1/8 = 4/8
that is because we only subtract the numerators (upper part) of the fractions due to the fact that the denominators are equal, now, 4/8 can also simplify to 1/2
therefore there are left 4/8 pound of trail mix or, what is the same, 1/2 pound of it
Answer:
Step-by-step explanation:
Let "a" and "m" represent the cost of an apple and a mango, respectively. Then Cameron's purchase can be represented as ...
4a +7m = 17.75
Gavin's purchase can be represented as ...
2a +5m = 10.75
Subtracting the first equation from twice the second gives ...
2(2a +5m) -(4a +7m) = 2(10.75) -(17.75)
3m = 3.75
m = 1.25
Then the price of an apple can be found from the second equation:
2a +5(1.25) = 10.75
2a = 4.50 . . . . . . . . . . subtract 6.25
a = 2.25 . . . . . . . . . . . divide by 2
The price of an apple was $2.25; the price of a mango was $1.25.
