PLEASE HELP! GIVING 11 POINTS! IN DESPERATE NEED!Dalia flies an ultralight plane with a tailwind to a nearby town in 1/3 of an hour. On the return trip, she travels the same distance in 3/5 of an hour. What is the average rate of speed of the wind and the average rate of speed of the plane? Let x be the average airspeed of the plane. Let y be the average wind speed. Initial trip: 18 = (x + y)1/3 Return trip: 18 = (x – y)3/5
What was Dalia's mph?
What was the wind speed?

Answer 2
Answer: Hello back,

18=(x+y)/3
18=(x-y)*3/5

==>(x+y)/3=(x-y)*3/5
==> 5(x+y)=9(x-y)
==>5x+5y=9x-9y
==>4x=14y
==>x=7/2y

18=(7/2y+y)/3
==>9/2*y=18*3
==>y=12
==> x=7/2*12=42
Sorry for the error.

The table gives the boiling point of water at different altitudes.Altitude (1,000 feet) Boiling Point of Water (°F)
0 212.0
0.5 211.1
1.0 210.2
2.0 208.4
2.5 207.5
3.0 206.6
4.0 204.8
4.5 203.9
Based on the table, the linear equation that represents the change in water’s boiling point for every 1,000-foot change in altitude has a slope of units.

Answers

Slope = raise / run

(211.1 - 212.0) / (0.5-0) = - 1.8

(210.2 - 211.1) / (1.0-0.5) = - 1.8

(208.4 - 210.2) / (2.0 - 1.0) = - 1.8

You can check, the other points. The slope is constant because the function is a linear equation,

Answer: - 1.8

Answer: -1.8

What is the area of the whole rectangle

Answers

Answer:

Step-by-step explanation:

it is divided into 4 rectangles

first rectangle ( 100 cm ^2)

area = l × b

= 10 × 10 = 100 cm^2

second rectangle ( 60 cm^2)

area = l × b

= 6 × 10 = 60 cm^2

third rectangle ( 20 cm^2)

area = l × b

= 2 × 10 = 20 cm^2

fourth rectangle ( 12 cm^2)

area = l × b

= 2 × 6 = 12 cm^2

so total area of the rectangle = 100 + 60 + 20 + 12 cm^2

= 192 cm^2

hope this helps

The sum of three consecutive odd integers is 105. What is the value of the smallest integer?

Answers

Answer:

Step-by-step explanation:

Answer:

33

Step-by-step explanation:

The sum is 105

n+n+2+n+4=105

3n+6=105

minus 6 both sideds

3n=99

divide both sides by 3

n=33

n+2=35

n+4=37

Write a congruence statement for the pair of triangles. Name the postulate or theorem that justifies your statement.

Answers

From the triangles, I think the congruence statement would be that of the ASA theorem. Triangle AWC is congruent to triangle RWC by virtue of the Angle-Side-Angle theorem. Hope this answers the question. Have a nice day.
