5/6-1/8 Solve by finding a common denominator

A)30/48
B)34/48
C)38/48
D)42/48

Answers

Answer 1

Answer:

  B)  34/48

Step-by-step explanation:

The easiest common denominator to find is the product of the denominators you have.

__

The difference is ...

  [tex]\dfrac{5}{6}-\dfrac{1}{8}=\dfrac{5}{6}\cdot\dfrac{8}{8}-\dfrac{1}{8}\cdot\dfrac{6}{6}\\\\=\dfrac{40-6}{48}=\boxed{\dfrac{34}{48}}[/tex]

__

Additional comment

The difference numerator and denominator have a common factor of 2, so can be reduced to 17/24. The denominator 24 could have been used as the common denominator from the start.

  5/6 -1/8 = 20/24 -3/24 = 17/24 . . . . reduced result

__

Using the least common denominator does not always result in a reduced sum or difference. If some other denominator is used (as here), then you can be assured that the result will need to be reduced to get to lowest terms.

Tuesday he used 3/5 as many of 1/8

Answers

Answer:

19/40 = 0.475 You can use either the fraction or the decimal

Step-by-step explanation:

3/5  - 1/8 = 3 · 8/5 · 8 - 1 · 5/8 · 5 = 24/40  - 5/40 = 24 - 5/40  = 19/40

Answer:

[tex] \frac{3}{5} - \frac{1}{8} = \frac{19}{40} [/tex]

TOTAL:

=0.475

Step-by-step explanation:

3/5 - 1/8 = 3.8/5.8 - 1.5/8.5 = 24/40

- 5/40 = 24-5/40 - 24-6/40 =19/40

For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of both denominators - LCM(5, 8) = 40. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 5 × 8 = 40. In the following intermediate step, it cannot further simplify the fraction result by canceling.

Answers

Answer:

A = 137°   a = 14 cm

B = 26°   b = 9 cm

C = 17°   c = 6 cm

Step-by-step explanation:

Cosine rule

[tex]c^2=a^2+b^2-2ab\cos (C)[/tex]

[tex]\implies C=\cos^{-1}\left(\dfrac{c^2-a^2-b^2}{-2ab}\right)[/tex]

where:

c is the side opposite angle Ca and b are the sides with C as the included angle.

Given:

a = 14 cmb = 9 cmc = 6 cm

[tex]\implies C=\cos^{-1}\left(\dfrac{6^2-14^2-9^2}{-2(14)(9)}\right)[/tex]

[tex]\implies C=\cos^{-1}\left(\dfrac{241}{252}\right)[/tex]

[tex]\implies C=16.99128694..\textdegree[/tex]

Sine Rule

[tex]\sf \dfrac{sinA}{a}=\dfrac{sinB}{b}=\dfrac{sinC}{c}[/tex]

(where A, B and C are the angles and a, b and c are the sides opposite the angles)

[tex]\sf \implies \dfrac{sinB}{9}=\dfrac{sin(16.991..)}{6}[/tex]

[tex]\sf \implies B=sin^{-1}\left(\dfrac{9sin(16.991..)}{6}\right)=25.99797699...\textdegree[/tex]

Sum of interior angles of a triangle = 180°

⇒ ∠A + ∠B + ∠C = 180°

⇒ ∠A = 180° - 25.997...°  - 16.9912...°

⇒ ∠A = 137.0107361...°

Triangle ABC has vertices at (5, 0), (- 1, - 4) , and (3, - 6) . What is the perimeter of ABC , rounded to two decimal places ?

Answers

Answer:

18.01 units to 2 dec. places.

Step-by-step explanation:

Calculate the length of the 3 lines of the triangle

AB = √ [(5 --1)^2 + ( 0 - -4)^2]

= √(36 + 16)

= √52

= 7.211.

BC = √ [(-1-3)^2 + (-4- -6)^2]

= √(16 + 4)

= √20

= 4.472.

CA = √ [(3-5)^2 + (-6-0)^2]

= √(4 + 36)

= √40

= 6.325.

So the perimeter = 7.211 + 4.472 + 6.325

= 18.008

What is halfway between 400,000 and 500,000?

Answers

Answer:

This is because 400,000 and 500,000 have no other numbers that could be the middle, so it has to be directly in-between both numbers.

__________________________________________________________

Questions related to this topic? Please ask me in the comments box.

Answer:

450,000

Step-by-step explanation:

500,000-400,000 = 100,000

100,000/2 = 50,000

400,000 + 50,000 = 450,000

Finding half of the value between 500,000 and 400,000 results in 50,000 and you can add that to the lesser value to get to the halfway point between the two numbers.

Which of the following represents a conditional
O A. The probability that it does not contain any nuts, given that the
candy is red
B. The probability that it contains nuts and is white
O c. The probability that the candy is not red
• D. The probability that the candy is blue

Answers

Answer:  Choice A

Reason:

The keyword "given" is a universal indicator we're dealing with conditional probabilities. It sets up prior knowledge to reduce down the sample space.

The fact that we know the candy is red means that we only focus on the red candies (and shrinks down the set).

Conditional probability is represented by probability that the candy is blue.

What is Conditional Probability?

One of the fundamental ideas in probability theory is the idea of the conditional probability formula. The conditional probability formula calculates the likelihood of an event, say B, given the occurrence of another event, say A.  

By knowing the conditional probability of event B given that event A has occurred and the individual probabilities of events A and B, the Bayes theorem may be used to calculate the conditional likelihood of event A given that event B has occurred.

We have,

Some red, white, and blue candies were placed in a bowl.

Write the ratio of green to black counters.

Answers

Answer:

3:1

Step-by-step explanation:

if 1/4 of the counters are black then it means the total counters are 4 and so there are 3 remaining and those become the green counters

The ratio of green to black counters is 3:1

What is the Ratio?

The ratio is defined as the comparison of two quantities of the same units that indicates how much of one quantity is present in the other quantity.

Given that A bag contains green and black counters, 1/4 of the counters are black.

Since, 1/4 is black counters therefore, 1 - 1/4 are green counters

So, there are 3/4 green counters

Ratio = (3/4)/(1/4) = 3/1  3:1

Hence, The ratio of green to black counters is 3:1
