"Find the missing side lengths in each pair of similar figures." Someone explain please

Answers

1. For triangle ABC, the value of 'x' and 'y' are 15 and 20 respectively.

2. For triangle XYZ, the value of 'x' and 'y' are 17 and 8 respectively.

What is a triangle?

A triangle is a two-dimensionalgeometrical figure that has three sides, three interior angles, and three vertices.

1. ΔABC and ΔXYZ are similar.

Therefore, (AB)/(XY) = (25)/(10)

⇒ (AB)/(XY) = 2.5

Here, AC = x, XZ = 6

Therefore, (AC)/(XZ) = 2.5

⇒ AC = 2.5(XZ)

⇒ x = (2.5)(6)

⇒ x = 15

Again, CB = y, ZY = 8

(CB)/(ZY)= 2.5

⇒ (y)/(8) = 2.5

⇒ y = (2.5) (8)

⇒ y = 20

2. For ΔABC

BC

= \sqrt{AB^(2) - AC^(2)}\n= \sqrt{34^(2) - 16^(2)}\n= √(900)\n= 30(Side can't be negative.)

Here, ΔABC and ΔXYZ are similar.

Therefore,

(BC)/(ZY)\n= (30)/(15)\n= 2

Now, AB = 34, XY = x

Therefore, (AB)/(XY) = 2

⇒ (34)/(x) = 2

⇒ x = (34)/(2)

⇒ x = 17

Again, AC = 16, XZ = y

Therefore, (AC)/(XZ) = (16)/(y) = 2

⇒ (16)/(y) = 2

⇒ y = (16)/(2)

⇒ y = 8

#SPJ3
AB is proportional to XY since they are similar triangles making it 25:10 or 5:2
so then AC:XZ  would be 5x:2x and 5x:6 so then its 15:6 since x is 3 basically set up proportions and so value of the big triangle to the small triangle would be at rails os 5:2

The equation P=28+2.54w models the relation between the amount of Randy's monthly water bill payment, P, in dollars, and the number of units of water, w, used. Interpret the P-intercept of the equation.

Answers

The P - intercept of the equation is 28

Solution:

Given equation models the relation between amount of Randy's monthly water bill payment and number of units of water used

P = 28 + 2.54w

Where,

"P" is the monthly water bill payment in dollars

"w" is the number of units of water used

Compare this equation with slope intercept form

Slope intercept form: y = mx + c

Where "m" is the slope of line and "c" is the y intercept

Therefore in given equation, P = 28 + 2.54w

2.54 is the slope and 28 is the P - intercept

The slope, 2.54, means that Randy’s payment increases by $2.54 when the number of units of water he used increases by 1

When "w" increases by 1 , then P increases by $ 2.54

The P –intercept means that if the number units of water Randy used was 0, the payment would be $28

When w = 0 ,

P = 28 + 0

P = $ 28

Thus the P - intercept determines the monthly payment bill

Answer:

The slope,  2.54, means that Randy's monthly water bill payment increases by  2.54  dollars for each unit of water used.
