find the perimeter of a rectangle whose length is 18 m and breadth is 5 m

Jayden's work rate is twice Chandra's work rate, and, the rooms cleaned

by Jayden is twice the number of rooms cleaned by Chandra.

Response:

Number of rooms in the house = 12

The time that Jayden takes to clean the house = 6 hours

Time that it takes Chandra to clean the house by herself = 12 hours

Time it takes both of them to clean the house = 4 hours

Required:

The number of rooms that Jayden clean and the number of rooms that

Chandra cleans when they work together.

Solution:

Given that the time it takes Jayden to clean the house is half the time

taken by Chandra.

Therefore;

The number of rooms Jayden cleans in 4 hours is twice the number of rooms cleaned by Chandra, which gives;

Ratio of the number of rooms cleaned by Jayden to the number cleaned by Chandra is 2 : 1

Total number of rooms cleaned = 12

[tex]Number \ of \ rooms \ cleaned \ by \ Jayden = \dfrac{2}{2 + 1} \times 12 = \underline{8 \ rooms}[/tex]

The number of rooms cleaned by Chandra = 12 - 8 = 4 rooms

Answer:

C. [tex]tan(B) =2[/tex]

Step-by-step explanation:

Here we can see tan(B) has a opposite side of 2 and adjacent of 1.

[tex]tan(B) = \frac{opposite}{adjacent}[/tex]

[tex]tan(B) = \frac{2}{1}[/tex]

[tex]tan(B) =2[/tex]

Answer:

[tex]\textsf{tan(B)}=2[/tex]

Step-by-step explanation:

The trig ratio for tan is tan(x) = O/A

where x is the angle,

O = side OPPOSITE to the angle, and

A = side ADJACENT to the angle

For angle B:

O = 2

A = 1

Therefore, [tex]\textsf{tan(B)}=\frac{2}{1}=2[/tex]

Using it's concept, it is found that the probabilities are as follows:

a) 0.6637.

b) 0.6947.

c) 0.1527.

A probability is given by the number of desired outcomes divided by the number of total outcomes.

In this problem, there is a total of 83 + 63 + 99 + 65 + 73 + 69 = 452 customers.

Item a:

63 + 99 + 65 + 73 = 300 are at least 20 but no older than 59, hence:

p = 300/452 = 0.6637.

Item b:

83 + 63 + 99 = 245 are younger than 40.

69 are older than 60.

Hence:

p = (245 + 69)/452 = 0.6947.

Item c:

69 customers are at least 60, hence:

p = 69/452 = 0.1527.

Answer:

$232.57

Step-by-step explanation:

1 year = 12 months

⇒ 5 years = 5 x 12 = 60 months

APR credit score of 700 or higher = 13.25%

(using the APR calculator) total payment over term of loan = $10,296.56

APR credit score of 699 or lower = 14.25%

(using the APR calculator) total payment over term of loan = $10,529.13

Savings = $10,529.13 - $10,296.56 = 232.57

Answer:

Step-by-step explanation:

The area of a shape is the amount of space it can occupy.

The length of BE is 8 units

The question is incomplete.

So, I will give a general solution

Assume that the length BE is 2/5 of length FH.

Then the length BE would be:

BE = 2/5 * FH

Substitute 20 for FH

BE = 2/5 * 20

Evaluate the product

BE = 8

Using the assumed value, the length of BE is 8 units

Answer:

a) $765.84

b) $1,531.68

Step-by-step explanation:

Simple interest formula:  SI = PRT

where P = principal amount of loan, R = annual rate of Interest in decimal format, and T = Time.

Given:

a) when T = 2:  

SI = 9573 x 0.04 x 2 = 765.84

b) when T = 4:  

SI = 9573 x 0.04 x 4 =  1531.68

Answer:

you would have 8 oranges and 5 apples

Answer:

360

Step-by-step explanation:

8% of 4500 is 360

The price is $27.00

Step-by-step explanation:

First you find 40% of 60 which is 24.

Next you subtract 24 from 60 (60-24) which equals 36.

Then you find 25% of the discounted price (36) which is 9.

Finally you subtract 9 from 36 (36-9) which is 27.

Conclusion:

So therefore the answer is $27.00.
