Answer:

2/4, 3/6, 4/8, 5/10, 6/12

Step-by-step explanation:

Equivalent fractions are fractions that have the same value or represent the same part of an object. If a pie is cut into two pieces, each piece is also one-half of the pie. If a pie is cut into 4 pieces, then two pieces represent the same amount of pie that 1/2 did. We say that 1/2 is equivalent to 2/4.

Fractions are determined to be equivalent by multiplying the numerator and denominator of one fraction by the same number. This number should be such that the numerators will be equal after the multiplication. For example if we compare 1/2 and 2/4, we would multiply 1/2 by 2/2 which would result in 2/4 so they are equivalent.

To compare 1/2 and 3/7 we would multiply 1/2 by 3/3 to produce 3/6. Since 3/6 is not the same as 3/7, the fractions are not equivalent.

Fractions equivalent to 1/2 are 2/4, 3/6, 4/8, 5/10, 6/12 ...

Fractions equivalent to 1/3 are 2/6, 3/9, 4/12, 5/15, ...

Fractions equivalent to 1/4 are 2/8, 3/12, 4/16, 5/20, ...

Fractions equivalent to 1/5 are 2/10, 3/15, 4/20, 5/25, ...

Fractions equivalent to 2/5 are 4/10, 6/15, 8/20, 10/25, ...

Answer:

She will need 191.55 pounds of flour.

Step-by-step explanation:

Given:

Audrey needs 2.4 pounds if flour for birthday cakes and 3.75 pounds of flour for wedding cakes.

If she plans on baking 72 birthday cakes and 5 wedding cakes.

Now, to find pounds of flour will she need.

So, the pounds of flour for 72 birthday cakes:

[tex]2.4\times 72[/tex]

[tex]=172.8\ pounds.[/tex]

And, the pounds of flour for 5 wedding cakes:

[tex]5\times 3.75[/tex]

[tex]=18.75\ pounds.[/tex]

Now, to get the pounds of flour she need we add the pounds of flour to make 72 birthday cakes and 5 wedding cakes:

[tex]172.8+18.75[/tex]

[tex]=191.55\ pounds.[/tex]

Therefore, she will need 191.55 pounds of flour.

Answer:

Rayshawn originally had $30.

Step-by-step explanation:

i) Rayshawn has a certain amount of money. Let us say this amount is $x.

ii) Rayshawn spends $20 which means that he is left with $(x - 20)

iii) it is also given that amount of money left after spending $20 is [tex]\dfrac{1}{3}[/tex] of the original amount, $x, the amount remaining is [tex]\dfrac{\$x}{3}[/tex].

iv) from the information given in ii) and iii) we get

     $(x - 20) = [tex]\dfrac{\$x}{3}[/tex],  Therefore we get 3x - 60 = x , therefore 2x = 60,

  Therefore x = $30. Rayshawn originally had $30.

Therefore, Rayshawn had $60 initially.

If Rayshawn spends $20 and ends up with 1/3 of the original amount, we can deduce that $20 represents 2/3 of the original amount.

since 1 - 1/3 = 2/3. Thus, each part (1/3) of the original amount corresponds to $20. Consequently, to find the original amount, we multiply $20 by 3, yielding $60. Therefore, Rayshawn originally had $60. This conclusion emerges from understanding that after spending $20, Rayshawn retains 1/3 of his original funds, implying that the $20 spent was equal to 2/3 of his initial sum. Thus, the inverse operation, multiplying by 3, unveils the original amount. Therefore, Rayshawn had $60 initially.

The perimeter of original garden is 42 feet

The perimeter of enlarged garden is 82 feet

Solution:

The perimeter of rectangle is given as:

Perimeter = 2(length + width)

Given that,

The garden is rectangular with width 6 feet and length 15 feet

Length = 15 feet

Width = 6 feet

Therefore, perimeter is given as:

Perimeter = 2(15 + 6)

Perimeter = 2(21)

Perimeter = 42

Thus perimeter of original garden is 42 feet

The new garden will be similar to the original one, but will have a length of 35 feet.

Length = 35 feet

Width = 6 feet

Therefore, perimeter is given as:

Perimeter = 2(35 + 6)

Perimeter = 2(41) = 82

Thus perimeter of enlarged garden is 82 feet

The given polygons are similar

Step-by-step explanation:

By observing the given diagrams, we can see that the respective angles are congruent.

Two shapes are said to be similar if they have same shapes or one shape is created by uniformly increasing or decreasing the side of other.

For this purpose we find the scale factor of greater to smaller image, if the scale factor is same for each side then the two shapes are similar

So,

The scale factor is:

[tex]\frac{EF}{AB} = \frac{3}{1} = 3\\\\\frac{FG}{BC} = \frac{9}{3} = 3\\\\\frac{GH}{CD} = \frac{15}{5} = 3\\\\\frac{EH}{AD} = \frac{21}{7} = 3[/tex]

We can see that the scale factor is same for all sides.

Answer: D

Step-by-step explanation:

Okun's law says that a country's gross domestic product (GDP) must grow at about a 4% rate for one year to achieve a 1% reduction in the rate of unemployment.

Option D is correct.

Since, According to Okun's law a country's gross domestic product (GDP) must grow at about a 4% rate for one year to achieve a 1% reduction in the rate of unemployment.

So, if the unemployment rate goes from 6% to 2%, that is reduce by 4%

Therefore, GDP is increase by 4(4 %) = 16 %

Thus, most appropriate answer is option D, that is GDP will increase by 11% .

Step-by-step explanation:

Answer: x≈3

Step-by-step explanation:

0.48 = log x , this could also be written as :

[tex]log_{10}[/tex] x = 0.48 , that is

x = [tex]10^{0.48}[/tex]

x = 3.01995172

x≈ 3

The solution to the equation 0.48 = log x is approximately 3.02 after converting it from logarithmic form into exponential form and calculating 10 to the power of 0.48.

To solve the logarithmic equation 0.48 = log x we have to rewrite this equation in exponential form. A logarithm log_b(x) = y in exponential form is represented as b^y = x. Considering that in your question it's not specified, this likely means a base of 10 is being used. Hence, the equation 0.48 = log x can be converted into exponential form: 10^0.48 = x.

Performing the calculation with a calculator (or by hand if you know how), we find x ≈ 3.02. Therefore, the solution for x in the given equation is approximately 3.02.

Answer:

x = -43/6

Step-by-step explanation:

To solve this equation, you solve for 'x' by isolating it. This means to move every other number to the other side of 'x'. You can move numbers when they 'cancel' out by doing the opposite (Adding and subtracting are opposites. Dividing and multiplying are opposites).

[tex]\frac{3x-2}{6}-\frac{4x+1}{4} = 3[/tex]

[tex]\frac{3x-2}{6}*\frac{2}{2}-\frac{4x+1}{4}*\frac{3}{3} = 3[/tex]     Multiply each fraction by a fraction that equals '1'. (2/2 = 1 and 3/3 = 1). This will give them a common denominator.

[tex]\frac{(3x-2)*2}{6*2}-\frac{(4x+1)*3}{4*3} = 3[/tex]     Multiply

[tex]\frac{(6x-4)}{12}-\frac{(12x+3)}{12} = 3[/tex]

[tex]\frac{(6x-4)-(12x+3)}{12}= 3[/tex]     Combine the fractions with the same denominator

[tex]\frac{(6x-4)-12x-3}{12}= 3[/tex]     Subtract binomials. -(12x+3) is -12x-3

[tex]\frac{6x-4-12x-3}{12}= 3[/tex]     Remove unnecessary brackets

[tex]-(6x+7)= 36[/tex]     Simplified right side

[tex]6x+7= -36[/tex]     Divided both sides by -1

[tex]6x= -36-7[/tex]     Subtract 7 from both sides

Answer: 4,690.33

Step-by-step explanation:

The formula for calculating amount is given by :

A = P [tex](1+r)^{n}[/tex]

Where :

A = amount = ?

P = Principal = 3500

r = rate = 0.05

n = number of years  = 6

substituting the given values into the formula , we have

A = 3500[tex](1+0.05)^{6}[/tex]

A = 3500 [tex](1.05)^{6}[/tex]

A = 3500 (1.340095640625)

A = 4690.3347421875

A = 4,690.33

Final answer:

To calculate Colin's investment with compound interest after 6 years, we use the formula for compound interest and determine that he will have £4690.33 to the nearest penny.

Explanation:

To calculate how much Colin will have after 6 years with compound interest, we use the formula for compound interest:

A = P(1 + r/n)nt

Where:

A is the amount of money accumulated after n years, including interest.

P is the principal amount (the initial amount of money).

r is the annual interest rate (decimal).

n is the number of times that interest is compounded per year.

t is the time the money is invested for, in years.

In Colin's case, we have:

P = £3500

r = 5% or 0.05

n is not mentioned, so we assume it is compounded once per year, thus n = 1

t = 6 years

Plugging these values into the formula:

A = £3500(1 + 0.05/1)1×6 = £3500(1 + 0.05)6

A = £3500 × (1.05)6 = £3500 × 1.340095

A = £4690.3325

To the nearest penny, Colin will have
£4690.33 after 6 years.
