Mathematics
1 answer:
Sati [7]3 years ago
8 0

Answer:

i = (4,0) , f= (-1,7)

v =

Where:

i_x = 4, i_y = 0 , f_x = -1, f_y = 7

And replacing we got:

v = =

And then the olution for this case would be:

e. <-5, 7>

Step-by-step explanation:

For this problem we know that we have a vector with the following initial and final points:

i = (4,0) , f= (-1,7)

Let v the vector if interest. And we want to find the component form from this info, so we can use the following formula:

v =

Where:

i_x = 4, i_y = 0 , f_x = -1, f_y = 7

And replacing we got:

v = =

And then the olution for this case would be:

e. <-5, 7>

Lindsay is 5 years younger than Mark. Seven years ago, the sum of their ages was 31.
Rashid [163]

Answer:

The present age of Mark is 25 years.

And present age of Lindsay is  20 years.

Step-by-step explanation:

Let us assume:

The present age of Lindsay = l

The present age of Mark = m

⇒ Age of Lindsay seven years ago =  (l -7) years

and Age of Mark seven years ago =  (m -7) years

According to question:

Lindsay is 5 years younger than Mark    ⇒   l = m  - 5

Seven years ago, the sum of their ages was 31  ⇒  (l-7) + (m -7)  = 31

So, the given set of equation are:

l = m  - 5    .........  (1)

(l-7) + (m -7)  = 31

⇒ ((m - 5) -7) + (m -7)  = 32  (from (1)

or, m -12 + m - 7  = 31

or, 2m = 31 + 19 = 50

⇒ m = 50 / 2  = 25, or m  = 25

Hence,the present age of Mark = 25 years

So,the present age of Lindsay = 25 - 5 = 20 years

There are 72 boys and 90 girls on the math team for the next math competition Mr. Johnson would like to arrange all the students
yawa3891 [41]

Answer:

Mr. Johnson can arrange 18 students in each row, that is 4 rows of boys and 5 rows of girls.

Step-by-step explanation:

Given:

Number of boys = 72

number of girls = 90

We need to arrange students in rows with equal number of only boys and only girls.

To find the maximum number (x) of boys or girls in each row, we will find the GCF (Greatest Common Factor) of the numbers 72 and 90, such that 'x' divides both numbers evenly without a remainder.

Now to find GCF we will factorize both numbers.

72 = 2\times2\times2\times3\times3

90= 2\times 3\times 3\times 5

from above we can say that;

GCF = 2\times 3\times 3 = 18

Hence Mr. Johnson can arrange 18 students in each row, that is 4 rows of boys and 5 rows of girls.
