Whole numbers are _____ integers. . . . .A. always. B. sometimes. C. never
guapka [62]

Whole numbers are sometimes integers.

\boxed{ \ The \ Answer \ is \ B \ }

<h3>Further explanation</h3>
  • The set of natural numbers (also called the set of counting numbers) is denoted by N:  \boxed{ \ N = \{1, 2, 3, ...\} \ }.
  • Natural numbers together with zero called are called whole numbers. The set of whole numbers is denoted by W: \boxed{ \ W = \{0, 1, 2, 3, ... \} \ }.
  • The set of natural numbers are not enough for all the number problems in everyday life. For example, natural numbers cannot be used to write some winter temperatures, since such temperatures may be less than zero i.e., negative numbers.
  • The set of integers are the union of the set of negative numbers with the set of natural numbers  and zero. The set of integers is denoted by Z:  \boxed{ \ Z = \{..., -3, -2, -1, 0, 1, 2, 3, ... \} \ }.
  • The set of negative integers is denoted by Z⁻: \boxed{ \ Z^- = \{ ..., -3, -2, -1 \} \ }.
  • The set of positive integers is denoted by Z⁺: \boxed{ \ Z^+ = \{1, 2, 3, ... \} \ }.
  • The set of non-negative integers are the set of all positive integers together with zero.
  • The set of non-positive integers are the set of all negative integers together with zero.

Conclusion:

Whole numbers are sometimes integers because negative integers are not part of whole numbers. In other words, whole numbers are not fully integers.

----------------------------------

Examples of integers around us:

  • The height of an airplane flight typically between 31,000 and 38,000 feet.
  • Ice melts at 0⁰C.
  • This diver is swimming at -20 m.

Match the proof. I need help please​
suter [353]

Answer:

D, E, F, B, C, A, G

Step-by-step explanation:

D is the midpoint of AB, E is the midpoint of BC and DB || FC

This is given information from the diagram and statement.

∠B ≅ ∠FCE

Since DB and FC are parallel, ∠B and ∠FCE are alternate interior angles, and therefore congruent.

∠BED ≅ ∠CEF

∠BED and ∠CEF are vertical angles, and therefore congruent.

ΔBED ≅ ΔCEF

By angle-side-angle, these triangles are congruent.

DE ≅ FE, DB ≅ FC

Corresponding parts of congruent triangles are congruent.

AD ≅ DB, DB ≅ FC, therefore AD ≅ FC

From transitive property of congruence.

ADFC is a parallelogram

Since AD and FC are congruent and parallel, ADFC is a parallelogram.

DE is parallel to AC

Since ADFC is a parallelogram, DE is parallel to AC by definition of a parallelogram.

Janet can do a job in 3 hours, and Garry can do the same job in 2 hours. If Janet works for 1 hour before Garry comes to help, h
lidiya [134]

Answer:

48 minutes

Step-by-step explanation:

Given that:

Time taken by Janet = 3 hours

Janet's rate = 1/3 job / hour

Time taken by Garry = 2 hours

Garry's rate = 1/2

Rate of working together :

1/3 + 1/2 = (2 + 3) /6 = 5/6 job/hour

If Janet works for one hour before Garry joins ;

1/3 of the job has been done by Janet

1 - 1/3 = 2/3 of the job left

Hence to finish the job together, it will take :

Fraction of JOB left ÷ rate of working together

(2/3 ÷ 5/6)

= 2 /3 * 6/5

= 12 / 15

= 4 / 5 hours

To minutes

(4/5) * 60

= 240/5

= 48 minutes
