Dalila bought her grandma a music album for $12.50 and then ordered three songs for herself. In total (before tax), she spent $16.37.
How much did Dalila spend on each song?

Answer:

-6

Step-by-step explanation:

g(1) would be equal to g(1) = -(1) - 5 = -6

So, the answer would be -6.

The value of g(1) is -6.

Given,

g(x) = -x - 5

We need to find g(1).

A function is given by f(x).

The value of x is called the domain.

The output we get after putting the domain x in the function is called the range.

Example:

f(x) = x + 2

x = 1

f(1) = 1 + 2 = 3

domain = 1

range = 3

Find g(x) at x = 1.

g(x) = -x - 5

Put x = 1

g(1) = -1 - 5

     = -6

g(1) = -6 is our answer.

Thus the value of g(1) is -6.

The cost of 4th book is $22.

In maths, the average value in a set of numbers is the middle value, calculated by dividing the total of all the values by the number of values. When we need to find the average of a set of data, we add up all the values and then divide this total by the number of values.

Given that, Jenny bought 4 books in a bookstore. The prices of the first 3 books were $10, $15 and $25.

Let the cost of 4th book be $x.

Now, average = (10+15+25+x)/4

(50+x)/4 =18

50+x =72

x=$22

Therefore, the cost of 4th book is $22.

Answer:

It would be translation and dilation.

Step-by-step explanation:

The sequence of transformations that will give a similar rectangle is the one in option C "translation and dilation".

Remember that two similar rectangles have the same shape, but different size.

This means that, if in the sequence of transformations we have a dilation, then the image of the transformation will be similar to the original rectangle.

Notice that there is only one option with a dilation which is option C.

"translation and dilation"

So that is the correct option.

Answer: Option C.

Step-by-step explanation:

The data is:

Destin walked 2km

Jane walked 4000ft.

Let's write both of those in the same units.

The data given is:

1ft = 0.0003048km.

and 4000ft is 4000 times that:

4000ft = 4000*1ft = 4000*0.0003048km = 1.22km

Then if we add those, we get:

Total distance = 2km + 1.22km = 3.22km

So we can already discard option D.

Now, we know that:

1km = 0.6214 miles.

then 3.22 km is 3.22 times that amount:

3.22km = 3.22*1km = 3.22*(0.6214 mi) = 2 miles

The correct option is C.

Answer:

Step-by-step explanation:

loan amount (P) = $10,000

interest is compound monthly :

A = P (1 + r/n)^n*t

find:

which of these loan terms will have the lowest total cost?

A) 2 years at 3% interest

B) 3 years at 3% interest

C) 4 years at 3% interest

D) 5 years at 3% interest

solution:

plugin the values into the formula to get the accumulated monthly interest.

A.   using 2 years at 3% interest

A = $10,000 ( 1 + 0.03 ) ¹² ˣ ²

                               12

   = $10,617.57

B.   using 3 years at 3% interest

A = $10,000 ( 1 + 0.03 ) ¹² ˣ ³

                                12

   = $10,940.51

C.   using 4 years at 3% interest

A = $10,000 ( 1 + 0.03 ) ¹² ˣ ⁴

                                12

   = $11.273.28

D.   using 5 years at 3% interest

A = $10,000 ( 1 + 0.03 ) ¹² ˣ ⁵

                                12

   = $11,616.17

therefore, based on the above terms, option A which is $10,617.57

                 has the lowest accumulated monthly interest. (total cost)

A) 2 years at 3% interest = $10,617.57

Answer:

The area of the new circle is 804.57 cm^2

Step-by-step explanation:

In this question, we are interested in calculating the area of the new circle of the radius of the old circle was doubled.

Let’s calculate the former radius first;

Mathematically;

Area of a circle = π * r^2

Thus;

201.06 = π * r^2

r^2 = 201.06/π

r^2 = 63.999

r = √63.99

r = 8 approximately

Now let’s double this radius and it becomes 2 * 8 = 16 cm

The new area will be ;

22/7 * 16 * 16 = 804.57 cm^2

(a) Equation: [tex]T_n = 11.25 - 1.25n[/tex]

(b) 7.5 gallons

Step-by-step explanation:

Given

Current Gas = 10 gallon

Every Hour = -1.25 gallon

Solving for (a): An equation for the scenario

This question represents an Arithmetic Progression and will be solved using the following formula:

[tex]T_n = a + (n - 1)d[/tex]

Where

[tex]a = 10[/tex]

[tex]d = -1.25[/tex]

Substitute these values in the formula

[tex]T_n = 10 + (n - 1) * -1.25[/tex]

[tex]T_n = 10 -1.25n +1.25[/tex]

Collect Like Terms

[tex]T_n = 10 + 1.25 - 1.25n[/tex]

[tex]T_n = 11.25 - 1.25n[/tex]

Solving for (b): In this case, n - 3

Substitute 3 for n in [tex]T_n = 11.25 - 1.25n[/tex]

[tex]T_3 = 11.25 - 1.25 * 3[/tex]

[tex]T_3 = 11.25 - 3.75[/tex]

[tex]T_3 = 7.5[/tex]

7.5 gallon of gas left

Step-by-step explanation: 17-3 = 14 and 14 is half of 28.

Answer:

Dafne originally had 28 apples.

Step-by-step explanation:

Dafne gave away 3 more than half of her apples, and she gave away 17 apples.

So the first step would be to find half of the original number of apples:

17-3=14

Now all we have to do is multiply by two:

14x2=28
