Answer:
7507
Step-by-step explanation:
8760-1253=7507
Answer: x < -15
Step-by-step explanation:
(-2)*(x) > 30
x < -15 The inequality reverses direction when a negative number is used in the manipulation (we divided by -2).
Part 1:
Proportion: 1/2 per foot.
Solve: The tree is 10 feet tall.
Solution in a sentence: To solve this, you take the shadows length, and double it to get objects actual height.
Part 2:
Proportion: 2 male horses to 3 female horses
Solve: There are 18 Female Horses.
Soulution in a Sentence: To solve this, you take the amount of male horses, divide it in half, then multiply it by 3 to get the answer.
Part 3:
Proportion: 3 drops to every 4 pints of water.
Solve: There are twelve drops in the 16 pints of water.
Solution: Every four pints of water, there is three drops. So you take the sixteen pints, divide it by four. Then, multiply it by three to get you answer.
Answer: 35.2
Step-by-step explanation: To estimate 55 percent of 64, you could round the 55 to 50 percent, and just find half of 64, which is 32. After this, because you only have 5 percent left over, you can take the number you got from 50% of 64 and move the decimal over one place to make it 3.2. Just add that number to 32 and you’ll get your answer.
Answer:
$22.20
Step-by-step explanation:
We are told that $13.32 only covered 3/5 of the cost. Does this mean it covered the whole cost? No. The 5 in the denominator represents the whole cost, and the 3 represents the fraction of the cost. In this case, 13.32 represents the 3, as it did not cover the whole cost.
Let's set up our equation by making 13.32 into a fraction.
13.32/x
We will represent the present's actual cost with the letter x.
13.32/x = 3/5
We want to make sure the 13.32 is in the numerator, equal to the 3 in the numerator in the 3/5 number, because we know that $13.32 only covered for a <em>fraction </em>of the present's cost, not the whole cost.
We solve this by doing cross multiplication. Multiply the 13.32 by the 5.
13.32 x 5 = 66.6
Next we divide 66.6 by 3 to get 22.2
66.6/3 = 22.2
This gives us our final answer of $22.20. This means that the cost of the original present was $22.20
