Answer:

In Diego’s pocket are worth $1.5.

Step-by-step explanation:

Given:

The coins in Diego’s pocket are worth 150% of a dollar.

Now, to find the worth in dollars in Diego's pocket.

So, as given the coins in Diego’s pocket are worth 150% of a dollar.

That means 150% of $1. As a dollar expresses 1$.

Thus, 150% of 1$.

[tex]=\frac{150}{100} \times 1[/tex]

[tex]=1.5\times 1[/tex]

[tex]=\$1.5.[/tex]

Therefore, in Diego’s pocket are worth $1.5.

Diego's coins are worth 150% of a dollar, which means they are worth $1.50. This was calculated by converting 150% to a decimal (1.50) and multiplying it by 1 dollar.

The question involves calculating the value of coins in terms of dollar amounts, which falls under the subject of Mathematics, specifically dealing with percentages and conversion of values.

Diego has coins in his pocket worth 150% of a dollar. To find out how much this is in dollars, we need to convert the percentage to a decimal by dividing by 100, which gives us 1.50. Therefore, the coins in Diego's pocket are worth $1.50. This is because 150% of 1 dollar is 1.5 times 1, which equals 1.5 or $1.50.

Remember, in math, percentages over 100% mean that you have more than the whole. So, 150% represents 1 whole (100%) plus half of another whole (50%), which in terms of dollars, translates to $1.50.

Answer:

We must pay back US$ 64,767.70 for the loan after 7 years.

Step-by-step explanation:

1. Let's review the data given to us for answering the question:

Loan amount = US$ 41,000

Duration of the loan = 7 years

Interest rate = 6.75% compounded annually

2. Let's find the future value of this loan after 7 years, using the following formula:

FV = PV * (1 + r) ⁿ

PV = Loan = US$ 41,000

number of periods (n) = 7 (7 years compounded annually)

rate (r) = 6.75% = 0.0675

Replacing with the real values, we have:

FV = 41,000 * (1 + 0.0675) ⁷

FV = 41,000 * (1.0675) ⁷

FV = 41,000 * 1.5797

FV = US$ 64,767.70

We must pay back US$ 64,767.70 for the loan after 7 years.

The area of a rectangle with side lengths of 6/8 meter and 4/10 meter is calculated by multiplying the lengths together after simplifying them to 3/4 and 2/5, respectively. The resulting area is 0.3 m².

To calculate the area of a rectangle, you multiply the length by the width. The question provides the side lengths as 6/8 meter and 4/10 meter. First, you may want to simplify these fractions to make multiplication easier. The fraction 6/8 simplifies to 3/4 after dividing both the numerator and the denominator by 2. The fraction 4/10 simplifies to 2/5 after dividing both the numerator and the denominator by 2.

Now, you multiply the simplified side lengths together to get the area:

Area = length × width
Area = (3/4) m × (2/5) m
Area = (3 × 2) / (4 × 5) [tex]m^2[/tex]
Area = 6 / 20 [tex]m^2[/tex]
Area = 3 / 10 [tex]m^2[/tex]
Area = 0.3 [tex]m^2[/tex]

The scale factor is 1.5. The dilation rule is : (x,y)-------(.15x,1.5y)

Step-by-step explanation:

Dilation is a transformation that maps an object to an image of the same shape as the original object to form a different size image.When a larger image is produced it's called an enlargement where as when a small image is produced, it's called a reduction.

The rule of dilation, with center as the origin follows;

(x,y)------(sx,sy) where s is the scale factor. To find the scale factor, select one of the vertices of the object and of the image at divide the coordinate of image with that of object.

Taking O(2,16) and O'(3,24),  the scale factor will be;

s*2=3

2s=3

s=3/2 =1.5

or

s*16=24

c = 3x-y = 3(4) - 5 = 7

Answer: 7

Final answer:

The minimum value of the function c=3x-y at the vertex point (4,5) of the feasible region is 7.

Explanation:

The question provided by the student involves finding the minimum value of a function of two variables, given by c=3x-y, at a certain point in the feasible region. Since the minimum is achieved at the vertex point (4,5), we can directly substitute these values into the function to find the minimum value.

To calculate the minimum value of the function c=3x-y at the point (4,5), we substitute x=4 and y=5 into the equation:

c = 3×4 - 5

c = 12 - 5

c = 7

Therefore, the minimum value of the function is 7 at the vertex point (4,5).

Answer:

Ron walked a total of 8 1/12 km

Step-by-step explanation:

Answer:

[tex]8\frac{1}{12} \; km[/tex]

Step-by-step explanation:

Distance walked by Ron on Monday = [tex]3\frac{3}{4} \; km[/tex]

Distance walked by Ron on Wednesday = [tex]4\frac{1}{3} \; km[/tex]

Now we will convert the given mixed fractions into improper fractions.

As we know that, a mixed fraction is composed of a whole number and a proper fraction.

Now,.

[tex]3\frac{3}{4} =\frac{3\times4+3}{4}=\frac{15}{4}[/tex]

[tex]4\frac{1}{3} =\frac{4\times3+1}{3} =\frac{13}{3}[/tex]

So, distance walked by Ron on Monday = [tex]\frac{15}{4}\; km[/tex]

Distance walked by Ron on Wednesday = [tex]\frac{13}{3} \; km[/tex]

Now, to find the total distance walked by Ron, we will add the distances walked by him on Monday and Wednesday.

So,

[tex]3\frac{3}{4} +4\frac{1}{3} =\frac{15}{4}+ \frac{13}{3}[/tex]

Now, we will find the LCM of the denominators of the given fractions.

The prime factorisation of 4 and 3 is,

4 = 2 × 2

3 = 3

So, LCM (3, 4) = 2 × 2 × 3 = 12

Now, we will convert each of the given fractions into their equivalent fractions with denominator 12.

[tex]\frac{15}{4}=\frac{15\times3}{4\times3}=\frac{45}{12}[/tex]

[tex]\frac{13}{3}=\frac{13\times4}{3\times4}=\frac{52}{12}[/tex]

So,

[tex]\frac{15}{4}+\frac{13}{3}=\frac{45}{12} +\frac{52}{12}=\frac{45+52}{12}=\frac{97}{12}[/tex]

Now, we will convert [tex]\frac{97}{12}[/tex] into improper fraction.

Now, 97 = 96 + 1 = 12 × 8 + 1

So, when '97' is divided by '12', then we get '8' as the quotient and '1' as the remainder.

So,

[tex]\frac{97}{12} = 8\frac{1}{12}[/tex]

Hence, Ron walked a total distance of [tex]8\frac{1}{12}[/tex] km in both the days.

Answer:

c = 4

Step-by-step explanation:

In g(x)=cx-3 when x is set to 0.5 , g(x)= -1.

We can solve for "c" when it is the only variable in the equation.

Substitute x for 0.5 and g(x) for -1. Isolate "c" to solve by doing reverse operations.

g(x) = cx - 3

g(0.5) = 0.5c - 3    Substitute x=0.5

-1 = 0.5c - 3       Substitute g(0.5) = -1

-1 + 3 = 0.5c - 3 + 3     Add 3 to both sides to start isolating c

2 = 0.5c

2/0.5 = 0.5c/0.5      Divide both sides by 0.5 to isolate c

4 = c      Value of c

c = 4     Standard formatting puts the variable on the left side

Therefore the value of c if g(0.5)=-1 is 4.

Answer:

c = 4.

Step-by-step explanation:

Substitute the given values x = 0.5 and g(x) = -1:

-1 = c(0.5) - 3

0.5c = -1 + 3 = 2

c = 2/0.5

c = 4.
