Answer:

19.5 kilometers

Step-by-step explanation:

to find how much he ran we can multiply the two numbers

In figure qr = 1/3pr. find pq

BaLLatris [955]

Answer:

PQ = 3.2

Step-by-step explanation:

$QR =\frac{1}{3} PR$

$QR =\frac{1}{3} \times 4.8$

$QR =1.6$

PQ = PR - QR

PQ = 4.8 - 1.6

PQ = 3.2

The bearing of a ship from a lighthouse is 050 work out the bearing of the lighthouse from the ship

GarryVolchara [31]

Bearing means there is a rightangled triangle so
we've got an angle of 90°
an angle of 50°
sum triangle is 180
180- (90 + 50 )
= 180 - 140
= 40°

WILL MARK BRAINLIEST what type of transformation is described by (x,y) —> (x+2, y+16)?

frosja888 [35]

This transformation takes a vector (x,y) and maps it to the vector (x+2, y+16). In other words, it moves the X coordinate of the vector 2 units to the right, and the Y coordinate of the vector is moved 16 units upwards.

If you would take a set of points and apply this transformation, you would see the entire set moving upwards and to the right, with no stretching ou rotating. This type of transformation is called a translation transformation.

In the year 1995, there were 1200 students at pine elementary school. In the year 2010 there were 1500 students. Find the rate o

AnnZ [28]

The rate of change from 1995 to 2010 is 20 students per year and the linear function that models the data will be: $y=20x-38700$

Explanation

In the year 1995, there were 1200 students and in the year 2010, there were 1500 students.

If $x$ represents the year and $y$ represents the number of students, then two points in form of $(x,y)$ will be: $(1995, 1200)$ and $(2010, 1500)$

So, the rate of change or slope = (change in value of y / change in value of x) $=\frac{1500-1200}{2010-1995}= \frac{300}{15}=20$

Now, plugging slope $(m)$ = 20 and first point $(x_{1}, y_{1}) =(1995,1200)$ into point slope form of linear equation $y-y_{1} =m(x-x_{1})$ , we will get.....

$y-1200=20(x-1995)\\ \\ y-1200=20x-39900\\ \\ y= 20x-39900+1200\\ \\ y= 20x-38700$
