Answer:

200 = 10 Hours, 400 = 5 Hours, 600 = 3 Hours & 18 Minutes.

Step-by-step explanation:

2000 / How many miles it travels per hour.

2000 / 200 = 10

2000 / 400 = 5

2000 / 600 = 3.3..

Answer:

Below

Step-by-step explanation:

Part A:

Like Pasta / Like Rice: A = 20

Like Rice / Do not like Pasta: B = 60

Total: C = 80

Do not like rice / Like Pasta: D = 40

Do not like rice & Pasta: E = 80

Total F = 120

Total G = 60

Total H = 140

Total I = 200

Part B: Using the rule of three:

If 200 represents 100%, then how much 80 represents?

(80 * 100) / 200 = 40%

40% did not like pasta nor rice.

Part C:

From the survey we know that:

30% like rice, and 20% dislike pasta. So yes, the survey reveals a greater dislike for rice.

Please help im so confused!!??

The formula for the surface area of a cone is SA=(pi)(r^2)+(pi)(r)(l)

L is the slant height of the cone.
Because pi is in the answer choices, there is no need to multiply either by pi so the new formula becomes
SA=r^2+(r)(l)
Now you just plug in what you know
Sa=(8^2) + (8)(15)
Sa=64+120
Sa=184(pi)

*dont forget to put the pi back in since you took it out in the beginning of the equation*

Your answer is A.

Hope this helps :)

A tree outside Ellie's house casts a 125-foot shadow. At the same time of the day, Ellie casts a 5.5-foot shadow. If Ellie is 4

Veronika [31]

Answer:

The tall of the tree is about 109.85 feet

Step-by-step explanation:

* Lets study the situation in the problem

- The tree and its shadow formed a right angle triangle with legs

x the tall of the tree and 125 feet the shadow of the tree

- Ellie and her shadow formed a right triangle with legs 4 feet and

10 inches the tall of Ellie and 5.5 feet the shadow of Ellie

- The two triangles are similar

- There is an equal ratio between the corresponding sides of the

similar triangles

# Ex: If triangles ABC and XYZ are similar

∴ AB/XY = BC/YZ = AC/XZ

* Lets use this rule to solve the problem

∵ The tall of the tree is x

∵ The tall of Ellie is 4 feet and 10 inches

- Lets change the tall of Ellie to feet only

∵ 1 foot = 12 inches

∴ 10 inches = 10/12 = 5/6 foot

∴ The tall of Ellie is 4 feet and 5/6 foot = 4 + 5/6 = 29/6 feet

∵ The shadow of the tree is 125 feet

∵ The shadow of Ellie is 5.5 feet

- By using similarity ratio

∴ Tall of tree/tall of Ellie = shadow of tree/shadow of Ellie

∴ x/(29/6) = 125/5.5 ⇒ using cross multiplication

∴ 5.5(x) = 125(29/6) ⇒ divide both sides by 5.5

∴ x ≅ 109.85 feet

* The tall of the tree is about 109.85 feet
