Basically, think of it as 3 / 1. 3√1 = 3/ 1 or 3/1 = 3 and 3√1 = 3

Andrea made a replica of the Empire State Building. The surface area of the model is 45 feet2.

iVinArrow [24]

87,120 ft²

1. Let's review the information given to us to answer the question correctly:

Surface area of the Empire State building replica = 45 square feet

Scale factor = 44

2. What is the surface area of the actual Empire State Building in square feet?

For answering the question, we will make the following calculations:

45 square feet = 9 feet * 5 feet or,

45 square feet = 10 feet * 4.5 feet, or,

45 square feet = 20 feet * 2.25 feet.

Now, let's apply the scale factor to all of these probable lengths of the sides of the surface area of the replica, as follows:

(9 *44) * (5 * 44) = 396 * 220 = 87,120 ft²

(10 * 44) * (4.5 * 44) = 440 * 198 = 87,120 ft²

(20 * 44) * (2.25 * 44) = 880 * 99 = 87,120 ft²

As we proved, no matter what are the lengths of the sides of the surface area of the replica. after applying the scale factor, the result is the same: 87,120 ft²

A student playing a board game believes that a standard six sided die is incorrectly weighted. The student thinks that the numbe

Answer:

Hₐ = P ( 1 ) > 1/6

Step-by-step explanation:

This is the answer because the question is asking you for the "alternative hypothesis" and that means that it's basically asking for the statement that agrees with what is being said.

Since we know that a student believes that he's seeing the number "1" too often, then we must find the equation that agrees with that statement, which is Hₐ = P ( 1 ) > 1/6.

P.S - I took the test and got a 100%.

Which of the following is the graph of the solution set of t – 4 ≥ 4t + 8 or 3t >14 – 4t?

Stells [14]

Answer:

Option (C)

Step-by-step explanation:

There are two inequalities,

t - 4 ≥ 4t + 8 ------(1)

3t > 14 - 4t ------(2)

By simplifying inequality (1),

t - 4 ≥ 4t + 8

t ≥ 4t + 8 + 4

t ≥ 4t + 12

t - 4t ≥ 12

-3t ≥ 12

t ≤ $\frac{12}{(-3)}$

t ≤ -4

By solving inequality (2),

3t > 14 - 4t

3t + 4t > 14

7t > 14

t > $\frac{14}{7}$

t > 2

From the given graphs, Option (C) will be the answer.
