Answer:

<em>Decimal numbers can't be the whole number but the whole number is always included in Decimal Numbers.</em>

Further,

Whole Number: It is an all-natural number including zero (0).

Example, 0, 1, 2, 3, 4, 5,.....

It is an infinite but countable number.

Decimal Number: It includes integer as well as non-integer numbers. It is defined as the number whose whole part and fractional part are separated by the decimals.

Example, 1.545, -58.1, 454,1041115.0001, etc.

A barrel of crude oil contains about 5.61 cubic feet of oil. How many barrels of oil contained in 1 mile (5280 feet) of a pipeli

8_murik_8 [283]

1)volume of the pipeline

The pipeline is a cylinder, therefore;
Volume (cylinder)=πr²h
r=radius
h=height of the cylinder

diameter=6 in*(1 ft / 12 in)=0.5 ft
raius=diameter / 2=0.5 ft / 2=0.25 ft.
height=5280 ft

Volume (pipeline)=π(0.25 ft)²(5280 ft)=330π ft³≈1036.73 ft³.

2) we calculate the number of barrel
1 mile of oil in this pipeline is 330π ft³ of oil.

1 barrel of crude------------------5.61 ft³
x----------------------------------330π ft³

x=(1 barrel*330π ft³) / 5.61 ft³=184.8 barrels

3) we calculate the price.

1 barrel---------------$100
184.8 barrels---------- x

x=(184.8 barrels * $100) / 1 barrel=$18,480

Solution: ≈$18,480

If 4-7x is 5 less than 23 what is the value of 3x

fredd [130]

Answer: The value is -6

Step-by-step explanation:

4 - 7(-2) = 18

18 + 5 = 23, so that is correct

If x = -2, then 3(-2) is -6

Which of the following gives a valid reason for using the given solution method to solve the system of equations shown? Equation

alukav5142 [94]

Answer:

* Elimination; a coefficient in Equation I is an integer multiple of a coefficient in Equation II.

* Elimination; a coefficient in Equation II is an integer multiple of a coefficient in Equation I.

Step-by-step explanation:

Equation I: 4x − 5y = 4

Equation II: 2x + 3y = 2

These equation can only be solved by Elimination method

Where to Eliminate x :

We Multiply Equation I by a coefficient of x in Equation II and Equation II by the coefficient of x in Equation I

Hence:

Equation I: 4x − 5y = 4 × 2

Equation II: 2x + 3y = 2 × 4

8x - 10y = 20

8x +12y = 6

Therefore, the valid reason using the given solution method to solve the system of equations shown is:

* Elimination; a coefficient in Equation I is an integer multiple of a coefficient in Equation II.

* Elimination; a coefficient in Equation II is an integer multiple of a coefficient in Equation I.

I need help plz ...i need this done by today !!!!

Deffense [45]

5. At First Street Elementary School, about 18% of the 610 students ride bicycles to school. About how many students ride bicycles to school?

Since 100% is equal to 610 students

Then 18% is equal to X students

Results X students = 18%*610students/100% = 109.8 students. As it does not make sense to split students, we have to round up to the nearest unit. Then we have 110 students. That would be approximately 18.03%, that rounded to the nearest unit is approximately 18%.

Answer 5) 110 students ride bicycles to school.

6. Write a proportion and answer each question using the conversion factor 1 inch = 2.54 centimeters.

a) Don is 67 inches tall. How many centimeters tall is he?

Since 1 inch is equal to 2.54 centimeters

Then 67 inches will be X centimeters

Results X cm = 67in * 2.54cm/1in = 170.18 centimeters

Answer 6a) Don is 170.18 centimeters tall.

b) Amira's pencil is 13.5 centimeters long. How many inches long is it?

Since 2.54cm is equal to 1inch

Then 13.5cm will be X inches

Results X inches = 13.5cm * 1in/2.54cm ≈ 5.315 approximately 5.32 inches

Answer 6b) Amira's pencil is approximately 5.32 inches long.

7. Use dimensional analysis to convert 60 miles per hour to feet per second. Remember that there are 5,280 feet in 1 mile.

Since 1 mile is equal to 5,280 feet

Then 60 miles will be X feet

Results X feet = 60 miles * 5,280 feet/1 mile = 316,800 feet

Since there are 3,600 seconds in 1 hour

316,800 feets per hour = 316,800 feets/hour x 1hour/3,600secs = 88 feet/sec

Answer 7) 60 miles per hour are converted to 88 feets per second

Hope this helps!
