Answer:
30
Step-by-step explanation:
(-) (-) = +
Therefore 15 - (-15) = 15 + 15 = 30
Answer:
10. First you multiply both sides by 3, making it 2x + 5 = 24
Then you subtract 5 from both sides making it 2x = 19
You dive both sides by 2 making x = 9.5
The answer is x = 9.5
11. First you need to find how much you need to pay each year. 12,000 x 0.05
you can make it easier by changing it to 120 x 5 = 600
You need to pay that for three years so 600 x 3 = 1800
Plus you need to pay the original money. 12,000 + 1,800 = 13,800
The answer is $13,800
12. First you change kilometers into centimeters. 172 km is 172,000 meters. 172,000 meters is 17,200,000
Then, you need to do 17,200,000 ÷ 500,000 but you can make it simple and do 172 ÷ 5 = 34.4
The answer is 34.4 cm
The correct answer is c. 100.
Step-by-step explanation:
Number of cards in the given pile = 24
Total number of diamond cards in the pile = 8
Probability of picking up a diamond in a draw of card from the pile is given by .
There are supposed to be 300 trials.
Therefore number of times a diamond card is picked from the pile is given by 300 × = 100.
Out of 300 trials to pick a card, about 100 times we can expect to have picked up a diamond card from the pile.
Y=log^2(x+7) equals y=(7+x)*LogN^2 OR {{x=(-7.0*LogN^2.0+y)*LogN^(-2.0)}}
Answer:
1. If you're looking for h then the answer should be 1/2 :)
Step-by-step explanation:
1. 3/4 minus 1/4 = 1/2
~~ We don't want the exact because 3/4 as to be greater than h-1/4~~
2. Find fraction what will equal less than 3/4
~~ 1/2 would be reasonable because 1/2 minus 1/4 is 1/4
~~~Hope this helps~~~
