Answer:

Given: DB = 7.2 cm, AE = 1.8 cm and EC = 5.4 cm and DE || BC.

[by basic proportionality theorem which states that if a line is drawn parallel to one side of a triangle the other two sides in distinct points, then the other two sides are divided in the same.

7.2

5.4

1.8

AD=

5.4

7.2×1.8

AD=

⟹AD=2.4cm

. If Henry plays both games conservatively (CC), find the probability that Henry will earn

larisa86 [58]

Answer:

a) 2/2 + 2/2 = 2

b) 2/2 + 1/2 = 3/2

c) 2/2 + 0/2 = 1

d) 0/2 + 0/2 = 0

Step-by-step explanation:

a) 2 points : 2/2 + 2/2 = 2

if henry wins both games than we get probability =2

b) 1 1/2 or 3/2 : 2/2 + 1/2 = 3/2

if henry wins one game and tie another game we get probability =3/2

c) 1 point: 2/2 + 0/2 = 1

if henry wins one game and loose second game, we get probability 1

d) 0 points: 0/2 + 0/2 = 0

if henry loose both games we get probability 0

The area of a trapezoid is 70.55 square feet. The length of the bases are 11.4 and 5.6 feet. What is the height of the trapezoid

olasank [31]

Answer:

The height is 8.3 feet

Step-by-step explanation:

The area of a trapezoid is calculated using the formula:

Area=½(sum of bases)*height

We substitute area=70.55, and the base lengths 11.4 and 5.6 feet and solve for the height.

$70.55 = \frac{1}{2} (11.4 + 5.6)h$

$70.55 = \frac{1}{2} (17)h$

$70 .55 = 8.5h$

$h = \frac{70.55}{8.5}$

$h = 8.3$
