if the survey, 9/25 of students ride the bus to school and 19/50 walk to school. what fraction of students ride the bus or walk

Elena-2011 [213]

1. $\dfrac{9}{25}$ of students ride the bus to school. Note that

$\dfrac{9}{25}=\dfrac{9\cdot 2}{25\cdot 2}=\dfrac{18}{50}.$

2. $\dfrac{19}{50}$ of students walk to school.

3. The fraction of students that ride the bus or walk to school is

$\dfrac{18}{50}+\dfrac{19}{50}=\dfrac{18+19}{50}=\dfrac{37}{50}.$

Answer: the fraction of students that ride the bus or walk to school is $\dfrac{37}{50}.$

Triangle XYZ is similar to Triangle PQR, in triangle XYZ, XY = 4cm, YZ=6cm, XZ=5cm, in triangle PQR PQ=8cm find remaining sides

kolezko [41]

Answer:

QR = 12 (cm), RP = 10 (cm)

Step-by-step explanation:

Corresponding sides of the triangles:

XY : PQ, YZ : QR, ZX : RP.

For similar triangles ratios of corresponding sides are the same

XY : PQ = 4 : 8 = 1 : 2

YZ : QR = 1 : 2

ZX : RP = 1 : 2

YZ : QR = 1 : 2

6 : QR = 1 :2, QR = 12 (cm)

ZX : RP = 1 : 2

5 : RP = 1 : 2, RP = 10 (cm)

Point A is located at (3,-6) and point A is located at (1-2). What is the scale factor?

Anuta_ua [19.1K]

Answer:

The scale factor is 3.

Step-by-step explanation:

Let the origin O(0,0) is the reference point and the coordinates of the point A are given by (3,-6).

Therefore, the distance OA is given by $\sqrt{(3 - 0)^{2} + (- 6 - 0)^{2}} = 3\sqrt{5}$ units.

Again, the coordinates of point A' are (1,-2).

Therefore, the distance OA' is given by $\sqrt{(1 - 0)^{2} + (- 2 - 0)^{2}} = \sqrt{5}$ units.

Hence, the scale factor is $\frac{OA}{OA'} = \frac{3\sqrt{5} }{\sqrt{5}} = 3$ . (Answer)
