Answer:

(a)ΔLAW≅ ΔWKL

(b) ASA rule of Congruency

Step-by-step explanation:

It is given that AW⊥WL and WL⊥KL, also ∠AWL=∠KLW ( Each 90°) and ∠ALW=∠LWK( Alternate angles) from the figure.

From ΔLAW and ΔWKL, we have

∠AWL=∠KLW ( Each 90°)

WL=WL (Common)

∠ALW=∠LWK( Alternate angles)

Therefore, by ASA rule of congruency,

ΔLAW≅ ΔWKL.

Hence proved.

Matty jogs 9 km/hr. Identify the correct conversion factor setup required to compute Matty's speed in m/s.

Anastaziya [24]

Answer:

2.5 m/s

Step-by-step explanation:

Matty's speed = 9 km/hr

We need to convert 9 km/hr to m/s

We know that,

1 km = 1000 m

1 hour = 3600 seconds

$v=9\times \dfrac{1000\ m}{3600\ s}\\\\=2.5\ m/s$

So, Matty jogs with the speed of 2.5 m/s.

HELP ASAP!! WILL MARK BRAINLIST!! A LOT OF POINTSS

Fittoniya [83]

Answer:

Black = 84 cm^2

Blue = 84cm^2

gold = 60.2cm^2

1 ornament = 228.2 cm^2

100 ornaments - 22820 cm^2

Step-by-step explanation:

Black is a rectangle = A = l*w = 7*12 = 84 cm^2

We have 2 blue This is a triangle so multiply by 2 the area of a triangle

2 * A = 2(1/2 b*h) = bh = 12*7 = 84 cm^2

We have 2 gold This is a triangle so multiply by 2 the area of a triangle

2 * A = 2(1/2 b*h) = bh = 8.6*7 = 60.2 cm^2

The total surface area for one ornament is

84+84+60.2 = 228.2

100 ornaments

Multiply by 100

100 *228.2 = 22820 cm^2

you take a group of 20 people going to the movies. kids’ tickets cost $4 each, and adults tickets $6 each. your total cost is $9

brilliants [131]

The number of kids in your group is 12.

Step-by-step explanation:

Given,

Number of people = 20

Cost of each kid ticket = $4

Cost of each adult ticket = $6

Total spent = $96

Let,

x be the number of kids ticket

y be the number of adult ticket

According to given statement;

x+y=20 Eqn 1

4x+6y=96 Eqn 2

Multiplying Eqn 1 by 4

$4(x+y=20)\\4x+4y=80\ \ \ Eqn\ 3$

Subtracting Eqn 3 from Eqn 2

$(4x+6y)-(4x+4y)=96-80\\4x+6y-4x-4y=16\\2y=16$

Dividing both sides by 2

$\frac{2y}{2}=\frac{16}{2}\\y=8$

Putting y=8 in Eqn 1

$x+8=20\\x=20-8\\x=12$

The number of kids in your group is 12.
