Do you agree with the rules of the council on tall buildings and urban habitat regarding spires and antennae? Are the Petronas towers really taller than the Sears tower?

Answers

Answer:

Yes, I agree

The Petronas Towers are taller than the Sears tower

Step-by-step explanation:

The rule regarding spires and antenna of the Council on tall buildings and Urban Habitat states that "an antenna is just functional - something with a technical purpose stuck on the top of a building after it is finished while spires are considered a continuation of the form of the building.

According to the Council, the Petronas Towers are taller than the Sears Tower because spires are included in a building's architecture while antennae are not.

The architectural height of the Petronas towers is 1,483ft

The architectural height of the Sears (now Willis) tower is 1,450ft

James is buying a chair that regularly costs $435. Today the chair is on sale for 47% off. If the tax rate is 8.5% , what is the sale price of the chair including tax

Answers

Answer: The sale price of the chair including tax = $221.83

Step-by-step explanation:

Regular price of chair = $435

Discount = 47%

Sales price = 47 % of (Regular price)

= $ 0.47 (435)

= $ 204.45

Tax rate = 8.5% = 0.085

Tax amount = Tax rate × Sales price

= 0.085 × 204.45

= 17.37825≈ $ 17.38

The sale price of the chair including tax = Sales price + Tax amount

= $ ( 204.45+17.38)

= $ 221.83

Hence, the sale price of the chair including tax = $221.83

60 is ​0.4% of what​ number? Use pencil and paper. Would you expect the answer to be a lot less than 60 ​, slightly less than 60 ​, slightly greater than 60 ​, or a lot greater than 60 ​? Explain.

Answers

Answer:

15000

Step-by-step explanation:

0.4%=0.004

0.004x=60

x=60/0.004

x=15000

The number 60 is 0.4 percentage of the number 15,000

Given data ,

To find the number that 60 is 0.4% of, we can set up the equation:

60 = 0.4 percentage of x

To solve for x, we need to convert 0.4% to its decimal form, which is 0.004:

0.004 * x = 60

Now we can solve for x by dividing both sides of the equation by 0.004:

x = 60 / 0.004

Dividing 60 by 0.004 gives us:

On simplifying the equation , we get

x = 15,000

Therefore, 60 is 0.4% of 15,000.

Since 0.4% is a very small percentage (less than 1%), we would expect the answer to be a lot greater than 60. This is because when a small percentage is applied to a number, the result will be significantly larger than the original number. In this case, the number that 60 is 0.4% of is 15,000, which is a lot greater than 60.

b > 15

The third number line shows the inequality.

What is Inequality?

Mathematical expressions with inequalities are those in which the two sides are not equal. Contrary to equations, we compare two values in inequality. Less than (or less than or equal to), greater than (or greater than or equal to), or not equal to signs are used in place of the equal sign.

Given:

Aiko is selling books for $12 each. She wants to make more than $180 in book sales.

and, the inequality 12b > 180 can be used to determine the number of books, b.

Now, solving the inequality

12b > 180

b > 180/12

b > 15

Hence, the third number line shows the inequality.

The equation C(l) = l3 – l2 + l + 2.5 models the cost to mail a package as a function of its length. To the nearest quarter inch, approximately what is the length of a package that costs $11.00 to mail? Enter your answer as a decimal.​

Answers

Answer:

2.25

Step-by-step explanation:

Given the cost model:

C(l) = l3 – l2 + l + 2.5

l = Length fo package

The length of a package that cost $11.00

11 = l³ - l² + l + 2.5

From the table given :

Length of mail which cost $11 will just be slightly greater Than 2 as the cost of 2 length mail cost 8.50

Taking l as 2.20

2.2^3 - 2.2^2 + 2.2 + 2.50 = 10.508

Taking a slightly higher value :

Put l = 2.25

2.25^3 - 2.25^2 + 2.25 + 2.50 = 11.078

Ww can conclude that the length of mail would be 2.25

Which type of function is represented by the equation 6y=2(x−5)

Answers

The type of the function that is represented by 6y = 2(x - 5) is a linear function

What are linear functions?

Linear functions are equations that have constant average rates of change. Note that the constant average rates of change can also be regarded as the slope or the gradient

How to determine the type of the function?

The equation of the function is given as

6y = 2(x - 5)

Divide both sides of the equation by 6

So, we have

y = 1/3(x - 5)

Open the bracket

y = 1/3x - 5/3

The form of the above equation is

y = mx + c

The equation represented by y = mx + c is a linear function

Hence, the type of the function that is represented by 6y = 2(x - 5) is a linear function

Equivalent Fractions with the LCD

1 1/2 = 36/24

5/6 = 20/24

3 = 72/24

Solution:

Rewriting input as fractions if necessary:

3/2, 3/8, 5/6, 3/1

For the denominators (2, 8, 6, 1) the least common multiple (LCM) is 24.

LCM(2, 8, 6, 1)

Therefore, the least common denominator (LCD) is 24.

Calculations to rewrite the original inputs as equivalent fractions with the LCD:

1 1/2 = 3/2 × 12/12 = 36/24

3/8 = 3/8 × 3/3 = 9/24

5/6 = 5/6 × 4/4 = 20/24

3 = 3/1 × 24/24 = 72/24
