Question

A rectangle has a width of 8 centimeters and an area of 160 square centimeters a similar rectangle has an area of 250 square centimeters. What are the dimensions of the larger rectangle?

Solution 1

I'm a bit confused and there is not a lot of information given to this.

From what I know, the dimensions of the larger rectangle can be found from length x width = 250 square centimetres.

Any multiplication problem that equals 250 could work out for length x width.

Question

Which point best approximates the root of 45

Solution 1

To solve for √45 we shall proceed as follows:

We rewrite 45 as 3²×5

thus

√45=√(3²×5)

pulling terms out from under the radical we obtain

3√5

thus the exact answer form is:

3√5

or the decimal form is:

6.70820393

We rewrite 45 as 3²×5

thus

√45=√(3²×5)

pulling terms out from under the radical we obtain

3√5

thus the exact answer form is:

3√5

or the decimal form is:

6.70820393

Question

Credit card A offers an APR of 27.29%, compounded monthly, while credit card B offers an APR of 27.12%, compounded daily. All else being equal, which card offers the better deal for the consumer?

Solution 1

The **effective **interest rate, also known as the **effective annual **interest rate, annual **equivalent **rate, or simply effective rate. The **card **which **offers **a **better deal **to the **customer **is **Credit card A.**

The **effective **interest rate, also known as the **effective annual **interest rate, annual **equivalent **rate, or simply effective rate, is the **interest **rate on a loan or **financial product **that is **restated **from the nominal interest rate and expressed as the **equivalent interest **rate if **compound **interest was **payable annually **in arrears. It is calculated by the formula,

EIR = [1+(i/n)]ⁿ - 1

The **effective **rate of **interest **on Credit **Card A** is,

Effective rate = [1+(i/n)]ⁿ - 1 = [1+(0.2729/12)]¹² - 1 = 30.97%

The **effective **rate of **interest **on Credit **Card B **is,

Effective rate = [1+(i/n)]ⁿ - 1 = [1+(0.2712/365)]³⁶⁵ - 1 = 31.14%

Since the **effective rate **of Credit card A is less than credit card B, therefore, the **card **which **offers **a **better deal **to the **customer **is **Credit card A.**

Solution 2

Credit card A, because it's effective interest rate is about o.16% less than that of credit card B.

Question

Daisy is cooking pasta. The recipe says she needs 480 grams of pasta for 4 people. How many kilograms will she need for 14?

Solution 1

480 grams of pasta = 480 grams x (1 kilogram / 1,000 grams) = 0.48 kilograms

Rule of three:

Pasta People

(kilograms)

0.48 → 4

x ← 14

x=(14 * 0.48)/4

x=1.68

Answer: She will need 1.68 kilograms of pasta for 14 people

Rule of three:

Pasta People

(kilograms)

0.48 → 4

x ← 14

x=(14 * 0.48)/4

x=1.68

Answer: She will need 1.68 kilograms of pasta for 14 people

Solution 2

**Answer:**

1.68 kilo grams are required for 14 people.

**Step-by-step explanation:**

First of all the answer is required in kilo grams and the data given is in grams.

Lets convert the given value to kilo grams;

480 grams = 0.48 kilo grams

If 0.48 kilo grams are required to cater 4 people then how many kilo grams are required to cater 14 people?

⇒ kilo grams

**1.68 kilo grams.**

Question

Kelly estimates it will take her 35 minutes to make the punch and 45 minutes to set up. Will Kelly finish before the guests arrive if she starts at 11:45 a.m? Explain your answer. (Kelly's guests will arrive at 1:30)

Solution 1

Kelly will have enough time to finish before the guests arrive because 45+35 = 1 hour and 10 mins, which adds that with 11:45, it would be 12:55 when she finishes. Making it possible.

Question

The mean age of swimmers are all of these is 10 what does a large mad tell you

Solution 1
