Segments, lines, etc. are parallel if their slopes are the same and if they are not coinciding(on top of each other).

Segment, lines, etc. are perpendicular if their slopes are the negative recipirocal of each other, such as 3 and -1/3.

By using the slope formula, (y2-y1)/(x2-x1), you find out that the slope of AB is -10/3 and the slope of CD is 1, so you can reason that they are neither.

Of the students in the college, 60% of the students reside in the hostel and 40% of the students are day scholars. Previous year
Assoli18 [71]

Answer:

the probability that the student is a hostlier is 0.6923

Step-by-step explanation:

The computation of the probability that the student is a hostlier is shown below

= (0.60 × 0.30) ÷ (0.60 × 0.30) + (0.40 × 0.20)

= (0.18) ÷ (0.18 + 0.8)

= (0.18) ÷ (0.26)

= 0.6923

Hence the probability that the student is a hostlier is 0.6923

17. Tiana deposited $500 into an
Ivahew [28]

Answer:

In 50 years the amount will be $ 2000.

Step-by-step explanation:

Tiana deposited $500 into a account at 6 % simple interest per Year .

Therefore, Principal (P) is $500

Amount (Principal + Interest) = $2000

Interest (I) = $2000 - $500 = $1500

Rate percentage (R) = 6% per Year

Let, The time be T years

Now, I = \frac{P . R . T}{100}

Or, T = \frac{100. I }{P . R}  

Or, T = (100×1500 ) ÷ ( 500× 6 )

<em>     </em><em>∴ T = 50 Years</em>

A classroom had 35 glue sticks if the ratio of glue sticks to glue bottles was 5:2 how many glue bottles did the classroom have
Alex73 [517]
You can think that for every 5 glue sticks, you will have 2 glue bottles. Since 35 means 5×7, then the number of glue sticks will be 2×7 which is 14
