The lenght of a rectangle is 3 inches more then its width. Its perimeter is 42 inches, find the dimensions of the rectangle

Answers

Answer:

The problem uses the perimeter formula.  P = 2w + 2l   where w is the width, and l is the length.

 

We know the length (l) is 3 inches longer than it's width (or l = w+3).  Substitute w +3 into Perimeter equation.

 

P = 2w + 2(w+3).  That simplifies to P = 4w + 6.

 

Since P + 42,   we have 42 = 4w +6.  With some simple algebra we find that w = 9 and l = 12.

Adrian needs to be at school at 7:45 am. It takes him 15 minutes to walk to school, 512 hour to eat breakfast, 0.7 hour to get dressed, and 0.15 hour to shower. What time should he wake up.

Answers

Correct question:

Adrian needs to be at school at 7:45 am. It takes him 15 minutes to walk to school, 5/12 hour to eat breakfast, 0.7 hour to get dressed, and 0.15 hour to shower. What time should he wake up.

Answer:

Adrian should wake up by 6.14 am

Step-by-step explanation:

Given;

time to walk to school, = 15 mins

time to eat breakfast = 5/12 hour = 25 mins

time to get dressed = 0.7hour = 42 mins

time to shower = 0.15 hour = 9 mins

time Adrian needs to be in school = 7.45 am

Count from this time he needs to be at school backwards by subtracting the time he will spend before reaching school;

7.45 am - 15 mins = 7.30 am

7.30 am - 25 mins = 7.05 am

7.05 am - 42 mins = 6.23 am

6.23 am - 9 mins = 6.14 am

Therefore, Adrian should wake up by 6.14 am

Answer:

The length of h is 3cm.

Step-by-step explanation:

You are looking for h. In order to find h you need the equation of area of a triangle, which is a=1/2bh. They give you base and they give you area. Plugging the numbers in, the equation is 7 7/8 cm^2= 1/2(5 1/4)(h). Now you solve by getting h by itself.

2(7 7/8 cm^2)= (1/2(5 1/4)(h))2

(15 3/4)/(5 1/4)= ((5 1/4)(h))/(5 1/4)

A barrel filled with oil is a cylinder with a diameter of 22 inches and a height of 35.5 inches. There are 231 cubic inches in a liquid gallon, how many gallons of oil does the barrel hold

Answers

Answer: The barrel holds about 58.44 gallons of oil .

Step-by-step explanation:

Given : For cylinder , diameter = 22 inches and height = 35.5 inches

radius = 11 inches [half of diameter]

Volume of cylinder  [tex]=\pi r^2h[/tex], where r= radius and h = height.

Volume of cylinder  [tex]=\dfrac{22}{7}\times(11)^2\times 35.5=13500.14\text{ cubic inches}[/tex]

Since, There are 231 cubic inches in a liquid gallon, so.

1 cubic inch = [tex]\dfrac{1}{231}[/tex] gallon.

13500.14 cubic inch = [tex]13500.14\times\dfrac{1}{231}\approx58.44\text{ gallons}[/tex]

Hence, The barrel holds about 58.44 gallons of oil .

To find:

The explanation of each part of the expression.

Solution:

The given expression is

[tex]276-35d[/tex]

Here, 276 is initial number of pages or total number of pages.

d is number of days she has been reading.

-35 represents the remaining pages decreased by 35 per day.

35d is number of pages she reads in d days she has been reading.

Therefore, total number of pages is 276 and number of pages she reads each day is 35.

Walter and Brian each have a CD collection. The number of CDs in Walter's collection can be represented by x. The number of CDs in Brian's collection is 3 times the number in Walter's collection. The total number of CDs in both collections is 144. What is x, the number of CDs in Walter's collection?

Answers

Answer:

36CDs

Step-by-step explanation:

The number of CDs in Walter's collection can be represented by x. The number of CDs in Brian's collection is 3 times the number in Walter's collection.

Hence, Brian's collection = 3x

The total number of CDs in both collections is 144.

We have the Equation:

x + 3x = 144

4x = 144

x = 144/4

x = 36

Therefore, the number of CDs in Walter's collection is 36 CDs
