What exactly is your question first of all?

The time taken to reach the goal of $3000 will be 36 months.

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that Lucas has $300 in his savings account and starts saving $75 per month. He wants to meet his savings goal of $3000.

The equation for the total cost will be formed as,

TC = 75m + 300

3000  = 75m + 300

3000 - 300 = 75m

2700 = 75m

m = 2700 / 75

m = 36 months

just absoulte value. |-1| = 1

Step-by-step explanation:

Step-by-step explanation:

officially, complementary angles complete each other to a total sum of 90 degrees.

supplementary angles complete each other to a total sum of 180 degrees.

angle 1 = 19× angle 2

90 = angle 1 + angle 2 = 19×angle 2 + angle 2 = 20×angle 2

angle 2 = 90/20 = 9/2 = 4.5 degrees.

angle 1 = 19×4.5 = 85.5 degrees.

and so, it seems to me, your teachers made a severe definition mistake and aimed for 180 degrees instead of the correct 90 degrees.

in that case, everything doubles.

angle 2 = 9 degrees

angle 1 = 171 degrees

If measure of an angle is 19-times measure of its complementary-angle, then measure of one angle is 85.5° and other is 4.5°.

Let us denote the measure of the angle as = "x" degrees.

The complementary angle is the angle that, when added to the given angle, forms a 90-degree angle.

The complementary-angle to "x" degrees is = (90 - x) degrees,

We know that the measure of the angle is nineteen times the measure of its complementary angle, we can write the equation as :

x = 19(90 - x),

x = 1710 - 19x,

20x = 1710,

x = 1710/20,

x = 85.5,

Therefore, the measure of the angle is 85.5 degrees. The measure of its complementary angle is 90 - 85.5 = 4.5 degrees.

Answer:

When f(x)= 3x – 1 and g(x) = 7x + 6,

f(g(x)) = 21x + 17

and

g(f(x)) = 21x - 1

Step-by-step explanation:

Given:

f(x) = 3x - 1

g(x) = 7x + 6

To find f(g(x)), substitute the value of g(x) into f(x).

f(g(x)) = f(7x + 6)

Substitute variable.

f(7x + 6) = 3(7x + 6) - 1

Distribute the 3 inside the parenthesis.

f(7x + 6) = 21x + 18 - 1

Subtract 1 from 18.

f(7x + 6) = 21x + 17

Therefore, f(g(x)) is 21x + 17.

To find g(f(x)), substitute the value of f(x) into g(x).

g(f(x)) = g(3x - 1)

Substitute variable.

g(3x - 1) = 7(3x - 1) + 6

Distribute the 7 inside the parenthesis.

g(3x - 1) = 21x - 7 + 6

Add 6 to -7.

g(3x - 1) = 21x - 1

Therefore, g(f(x)) is 21x - 1.

Step-by-step explanation:

Answer:

27/50

Step-by-step explanation:

54 is another way of writing 54 hundredths, or as a fraction, 54/100. Asking for a simplified fraction is asking you to reduce the numerator and denominator by any common terms. 54 and 100 are both divisible by 2, so we get to 27/50. These have no factors in common, so 27/50 is our simplified fraction.

Answer:

D. 1356.5 cm³

Step-by-step explanation:

The volume of a cone can be represented by:

V = (π)(r²)(h/3)

Substitute the known values:

π = 3.14

r = 12

h = 9

V = (3.14)(12²)(9/3)

Square 12.

V = (3.14)(144)(9/3)

Divide 9 by 3.

V = (3.14)(144)(3)

Multiply 3.14 and 144.

V = (452.16)(3)

Multiply 452.16 and 3.

V = 1356.48

Round to the nearest tenth.

V = 1356.5.

                                             13/4 = x

If Satchmo bought half pound of mangoes for $6 then he pay $39 for 13/4 pounds of mangoes.

A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0.

Given that Satchmo bought half pound of mangoes for $6

We need to find the amount he has to pay for 13/4 pounds of mangoes.

Let x be the  amount he has to pay for 13/4 pounds of mangoes..

We find the value of x by forming a proportional equation by given data.

1/2/6=13/4/x

1/12=13/4x

Apply cross multiplication

4x/12=13

x/3=13

x=39

Hence, Satchmo pay $39 for  13/4 pounds of mangoes.
