He lives 50 m from a park.

Luba_88 [7]

We have to find the perimeter of the park and then add 50m to that

Perimeter = 2(l+b)

= 2(275+200)

= 2* 475

= 950m

Therefore: Total distance covered = 950+50 = 1000 m(1km)

If x + 5y = -11 and 2x − 3y = 17, what is the value of x + y?

aev [14]

X+5y=-11 (1)
2x-3y=17 (2)

2(1)-(2)
2x+10y-2x+3y=-22-17
13y=-39
y=-3

Sub y=-3 in (1)
x+5(-3)=-11
x=4

So x+y= -3+4 =1

What is the value of h in the figure below? In this diagram BAD~CBD

liberstina [14]

Answer:

The correct option is E. 8

The value of h is 8 unit.

Step-by-step explanation:

Given:

Δ BAD ~ Δ CBD

AC = 20

DC = 4

∴ $AD = AC - DC=20-4=16$

To Find:

h = ?

Solution:

Δ BAD ~ Δ CBD ................Given

If two triangles are similar then their sides are in proportion.

$\frac{BD}{CD} =\frac{AD}{BD} =\frac{BA}{CB}\ \textrm{corresponding sides of similar triangles are in proportion}\\$

On substituting the given values we get

$\dfrac{BD}{CD} =\dfrac{AD}{BD}$

$\dfrac{h}{4} =\dfrac{16}{h}\\\therefore h^{2}=64\\\therefore h=8\ unit$

The value of h is 8 unit.
