Mathematics
1 answer:
andrezito [222]3 years ago
3 0

Answer:

1) false

2)false

3)false

Step-by-step explanation:

for number 1 you can tell it's false because if you look after the decimal, the right one is larger than the left one, they're saying it's greater than

for number 2 you can tell it's false because it's equal to. Anytime you see a less than or grater than equation like this you have to remember that if it's the same without a 0 it doesn't matter, it's the same if you add a 0 after the decimal.

For number 3 you can tell it's false because 3 is less than 7 (in the hundreths place.)

Hope This Helps!!!

Answer:

a. y = 3x + 4.5 & y = 7x + 2

b. x = 0.625 (year)

c. 6.375 feet

Explanation:

Type A starts at 4.5 and Type B starts at 2 ,each year can be marked as x

type A grow 3 inches per year = 3x

type B grows 7 inches per year = 7x

y = the total height

Since they both equal to y, you can set them equal to each other

3x + 4.5 = 7x +2

After solve you get answer for b

Work:  3x + 4.5 = 7x + 2

              4.5 = 4x + 2

               2.5 = 4x

              0.625 = x

Substitute the value of x you got from part b into each equation then you will get 6.375 as your y value which is also your height

A cooler contains eleven bottles of sports drink: five lemon-line flavored and six orange flavored. You randomly grab a bottle a
Elenna [48]

Answer:

The probability that you would choose lemon-lime and then orange is 3/11 =.273.  

Step-by-step explanation:

These are 'dependent events', which mean that your the event is affected by previous events.  So, because you have eleven total bottles (five lemon-lime and six orange) and you do not replace the first bottle, that would only leave you with ten bottles remaining.  The probability that you will pick the lemon-lime on the first choice is 5/11 because all of the bottles are there.  However, your second choice will only include ten total bottles since you already took one.  The probability that you would choose orange would be 6/10.  When you multiply these two fractions and reduce to simplest form, you get 3/11.
