Answer:

a. 5/20, 8/20

Step-by-step explanation:

1/4 and 2/5

a. 5/20, 8/20

5/20

Divide both numerator and denominator by 5

= 1/4

8/20

Divide both numerator and denominator by 4

= 2/5

b. 1/20, 2/20

1/20 =1/20

2/20

Divide both numerator and denominator by 2

= 1/10

c. 1/9, 2/9

Both fractions can't be further simplified

= 1/9, 2/9

d. 5/20, 4/20

5/20

Divide both numerator and denominator by 5

= 1/4

4/20

Divide both numerator and denominator by 4

= 1/5

The correct answer is a. 5/20, 8/20

= 1/4, 2/5

5 / 20 and 8 / 20 are pairs of fractions with a common denominator that are equivalent to 1/4 and 2/5

We are ask to find the equivalent of the pairs of fractions with a common denominator 1 /4 and 2 / 5.

The logic is to reduce by dividing the options with same numerator and denominator to get the equivalent of the fraction required.

Therefore,

5 / 20 and 8 / 20

5 / 20 ÷ 5  / 5 = 1 / 4

8 / 20 ÷ 4 / 4  = 2/5

Base on the answer you can see that when we reduced option A fractions, they are the same with the required fractions.

Therefore, 5 / 20 and 8 / 20 are pairs of fractions with a common denominator that are equivalent to 1/4 and 2/5

Answer:

y= -6x +1

Step-by-step explanation:

The equation of a line is usually written in the form of y=mx +c, where m is the gradient (or slope) and c is the y-intercept.

In order to find the equation of a line, you would need 2 things:

① Gradient (← can be found)

② Coordinate (✓ we have 2 coordinates here)

To find the gradient, use the gradient formula below:

[tex]gradient = \frac{y1 - y2}{x1 - x2} [/tex]

[tex]m = \frac{ - 5 - ( - 17)}{1 - 3} \\ m = \frac{ - 5 + 17}{ - 2} \\ m = \frac{12}{ - 2} \\ m = - 6[/tex]

Substitute the value of m into the equation:

y= -6x +c

To find the value of c, substitute a pair of coordinates.

When x=1, y= -5,

-5= -6(1) +c

c -6= -5

c= 6 -5

c= 1

Thus, the equation of the line is y= -6x +1.

Answer:

1/4

Step-by-step explanation:

Absolute values are always positive.

The absolute value is |1/4|

To understand this let's first understand the definition of absolute value.

Absolute value - The non-negative value of a number without regard to its sign. For example, the absolute value of 5 is 5, and the absolute value of −5 is also 5. The absolute value of a number may be thought of as its distance from zero along real number line.

Therefore the absolute value of -1/4 is just 1/4.

Also, remember that to indicate that it's the absolute value you have to add a " | " before and after the number. Like this |1/4|

Step-by-step explanation:

Let x be the number

2/3 x+4 = 22

Subtract 4 from each side

2/3x +4-4 = 22-4

2/3 x = 18

Multiply each side by 3/2

3/2 ( 2/3x) = 18 * 3/2

x = 27

Answer:

Step-by-step explanation:

If you have two marbles in a bag and you are choosing the marbles randomly twice, then we can look at fractions.

Each time, you have a 0.5 chance of picking the silver marble. After you pick that, you have another 0.5 chance of picking the silver marble again.

This applies with any combination.

This means that the probability of you getting two silvers in a row is 0.25.

Since the marbles are the same size and nothing is stopping you from choosing one, this probability applies to all combinations possible.

Correct question is;

Among all pairs of numbers with a sum of 149, find the pair whose product is maximum. Write your answers as fractions reduced to lowest terms

Answer:

The pair whose product is maximum is 149/2 and 149/2

Step-by-step explanation:

We are told that pair of number with sum as 149 and to find the product that is maximum.

Now,let x and y be the numbers. Thus;

x + y = 149 and xy is maximum.

So, y = 149 - x

Thus, plugging 149 - x for y into the product equation gives; x(149 - x). This can be expanded to be -x² + 149x.

Using method of completing the square, we will arrive at;

-(x² - 149x) = -(x² -149x + (149/2)²) + (149/2)² = (149/2)² - (x - (149/2))²

Now, the expression gotten will have a maximum of (149/2)² when (x - (149/2))² has its minimum value of zero. This means that when x = 149/2, as x moves away from 149/2, (149/2)² would be reduced by the square of the difference between the value of x and 149/2, and the square would always be positive.

Thus, the maximum product in it's simplest form is x = y = 149/2

Answer:

5

Step-by-step explanation:

The formula is [tex]\sqrt{(x_{1}-x_{2})^{2} +(y_{1}-y_{2}})^{2} }[/tex]

[tex]x_{1}[/tex]=-3 [tex]x_{2}[/tex]=0

[tex]y_{1}[/tex]=5 [tex]y_{2}[/tex]=1

[tex]x_{1}- x_{2}[/tex]=-3

[tex]y_{1}- y_{2}=4[/tex]

Therefore: [tex]\sqrt{(-3)^{2}+4^{2} } =\sqrt{9+16} =\sqrt{25}=5[/tex]

Answer:

Step-by-step explanation:

Let the original price be x

The discounted price for a clearance sale = 30% of x

If the price tag after discounting = $199.

Using the relationship to find the original price x

Original price - discounted price = Current price tag after discounting

x - 0.3x = 199

0.7x = 199

Divide both sides by 0.7

0.7x/0.7 = 199/0.7

x = $284.29

Hence the suit's original price is approximately $284.29

Answer:

In the first sequence, the next term here is 1. In the second sequence; the next term is 162.

An arithmetic sequence is sequence of integers with its adjacent terms differing with one common difference.

In the first sequence,  256, 64, 16, 4, ...

Consider ratio of the next term with its preceding term, so we will get the common ratio;

4/ 16 = 1/4

So, we can see that the next term of the sequence is 1/4 times the previous term.

Hence, the unknown term will be; 1/4 times of previous term.

That is , 1/4 × 4 = 1

Therefore, the next term here is 1

In the second sequence; 2, 6, 18, 54, ...

Do the same procedure as above, we will get the common ratio as :

54 / 18 = 3

Thus, the next term is 3 times the preceding term, that is :

3 × 54 = 162

Hence, the next term is 162
