If Natalia paid $12 for the necklace, then Each t- shirt cost $7.

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value. Unitary method is a technique by which we find the value of a single unit from the value of multiple devices and the value of more than one unit from the value of a single unit.

We are given that Natalia paid $40 for 4 t-shirts and a necklace.

If Natalia paid $12 for the necklace, then;

We need to find the cost of each shirt.

Therefore,

cost of 4 t- shirt + 1 neclace = 40

40 - 12 = 28

Cost of 4 t- shirt = 28

Cost of 1 t- shirt = 28/4 = 7      

Hence, the cost of each t shirt is $7.

Answer:

A = 15.87 m²

Step-by-step explanation:

the area (A) of a triangle is calculated as

A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the perpendicular height )

here b = 6.9 and h = 4.6 , then

A = [tex]\frac{1}{2}[/tex] × 6.9 × 4.6 = 3.45 × 4.6 = 15.87 m²

Answer:

the abswer is D

Step-by-step explanation:

[f○g](x)=(9x+12)/9+8/3=x+8/3

[g○f](x)=9(x/9 + 4/3)+12=x+24

so for the same x they are not inverses

In summary |-13.5 - (-4 1/5)| × 1.4 + (-2)²2 is equal to 17 3/5.

How to solve?

|-13.5 - (-4 1/5)| = |-13.5 + 4 1/5| [Subtracting a negative is equivalent to adding a positive]

= |-9 4/5|

= 9 4/5

Now, we can substitute the values and simplify the expression:

|-13.5 - (-4 1/5)| × 1.4 + (-2)²2

= 9 4/5 × 1.4 + (-2)²2

= 13 3/5 + 4

= 17 3/5

Therefore, |-13.5 - (-4 1/5)| × 1.4 + (-2)²2 is equal to 17 3/5.

An equation is a mathematical statement that shows that two expressions are equal. It consists of two sides, a left-hand side (LHS) and a right-hand side (RHS), connected by an equal sign (=).

Answer:

[tex]x=\dfrac{\ln \left(\frac{21}{25}\right)}{\ln 6125}[/tex]

Step-by-step explanation:

Given equation:

[tex]2 \cdot 5^{3x+2} = 6 \cdot 7^{1-2x}[/tex]

Divide both sides of the equation by 2:

[tex]\implies 5^{3x+2} = 3 \cdot 7^{1-2x}[/tex]

Take natural logs of both sides:

[tex]\implies \ln \left(5^{3x+2}\right) = \ln \left(3 \cdot 7^{1-2x}\right)[/tex]

[tex]\textsf{Apply the product law:} \quad \ln xy=\ln x + \ln y[/tex]

[tex]\implies \ln 5^{3x+2} = \ln 3 + \ln 7^{1-2x}[/tex]

[tex]\textsf{Apply the power law:} \quad \ln x^n=n \ln x[/tex]

[tex]\implies (3x+2)\ln 5 = \ln 3 + (1-2x)\ln7[/tex]

Expand:

[tex]\implies 3x\ln 5+2\ln 5=\ln 3+\ln7-2x\ln7[/tex]

Collect the terms in x on the left side and the constants on the right side of the equation:

[tex]\implies 3x\ln 5+2x\ln7=\ln 3+\ln7-2\ln 5[/tex]

Factor out the common term x on the left side:

[tex]\implies x(3\ln 5+2\ln7)=\ln 3+\ln7-2\ln 5[/tex]

[tex]\textsf{Apply the power law:} \quad n \ln x=\ln x^n[/tex]

[tex]\implies x(\ln 5^3+\ln7^2)=\ln 3+\ln7-\ln 5^2[/tex]

Simplify:

[tex]\implies x(\ln 125+\ln 49)=\ln 3+\ln7-\ln 25[/tex]

[tex]\textsf{Apply the product law:} \quad \ln x + \ln y=\ln xy[/tex]

[tex]\implies x(\ln (125 \cdot 49))=\ln (3\cdot 7)-\ln 25[/tex]

[tex]\implies x(\ln 6125)=\ln 21-\ln 25[/tex]

[tex]\textsf{Apply the quotient law:} \quad \ln x - \ln y=\ln \left(\dfrac{x}{y}\right)[/tex]

[tex]\implies x(\ln 6125)=\ln \left(\dfrac{21}{25}\right)[/tex]

Divide both sides of the equation by ln 6125:

[tex]\implies x=\dfrac{\ln \left(\frac{21}{25}\right)}{\ln 6125}[/tex]

The probability of selecting a car from the rental parking lot is 0.6 or 60%.

Probability of selection refers to the likelihood or chance of selecting a particular item or event from a group or population. It is a mathematical concept used in statistics, mathematics, and science to describe the likelihood of an event occurring, given the set of possible outcomes.

The probability of selecting a car from the rental parking lot can be found by dividing the number of cars by the total number of vehicles:

P(Car) = Number of Cars / Total Number of Vehicles

In this case, there are 5 trucks, 9 cars, and 1 van, so the total number of vehicles is:

Total Number of Vehicles = 5 + 9 + 1 = 15

Number of Cars = 9

Therefore, the probability of selecting a car from the rental parking lot is:

P(Car) = Number of Cars / Total Number of Vehicles

           = 9 / 15

           = 3 / 5

            = 0.6

So the probability of selecting a car from the rental parking lot is 0.6 or 60%.

Answer:

C. 9 times larger

Explanation:

where, r = radius of a cylinder and h = height of the cylinder. This means that the volume of a cylinder will be 9 times larger if the radius is multiplied by 3.

The volume of the display case is 60 + 120 = 180. The correct answer is B. 36.

Volume is a measure of the three-dimensional space something occupies or contains. It is often expressed as a calculation of length x width x height. It can also refer to the amount of something, such as the volume of a liquid, or the amount of space a container holds. Volume is an important concept in mathematics, science, engineering, and many other fields. It is used to measure the size of a solid, liquid, or gas, and to quantify the amount of material in an object or a space.

The volume of a rectangular prism is determined by multiplying its length, width, and height. The volume of a display case made of one rectangular prism stacked on top of a second rectangular prism is equal to the sum of the volumes of each rectangular prism.

The volume of the first rectangular prism is 3 x 4 x 5 = 60.
The volume of the second rectangular prism is 4 x 5 x 6 = 120.

Therefore, the volume of the display case is 60 + 120 = 180. The correct answer is B. 36.

To find the greatest common factor of these three terms, we need to factor each one and identify the highest power of each factor that is common to all three. Then, we can multiply those factors together to find the GCF.

Let's begin by factoring each term:

1/4n^2m^3 = (1/4) * n^2 * m^3

5/20n^7m^8 = (1/4) * n^7 * m^8

3/12n^2m^8 = (1/4) * n^2 * m^8

Now, we can see that each term has a common factor of 1/4, so we can factor that out:

1/4 * (n^2 * m^3)

1/4 * (n^7 * m^8)

1/4 * (n^2 * m^8)

To find the highest power of each factor that is common to all three terms, we need to look at the exponents. The highest power of "n" that is common to all three terms is 2, and the highest power of "m" that is common to all three terms is 3. Therefore, the GCF is:

1/4 * n^2 * m^3

This simplifies to:

n^2m^3/4

So, the correct option is (c) n^2m^3/4.

Answer: It is not possible for the length of the third side of a triangle to be an integer when the lengths of the other two sides are not integer.

Step-by-step explanation:

When the other two sides of a triangle are 5.3 and 0.4 in length, the third side cannot possibly have an integer length. This is so because any two sides of a triangle must have lengths that are greater than the length of the third side. In this instance, 5.3 + 0.4 = 5.7, which still falls short of any integer number for the third side's length.

Aerobics is a form of physical exercise that combines rhythmic aerobic exercise with strength and stretching training routines with the goal of improving all elements of fitness ( cardio-vascular fitness, flexibility and muscular strength ).

The percentage  can be  found by  dividing the  value by the total value and then multiplying the  result by 100. The formula  used to  calculate  the  percentage is: [tex]\frac{value}{total value}[/tex]×100%.

To find out  how many of the  students in Ms.  Vitals aerobics class are Hispanic,

first of all to determine  the percentage of students  are not African American or Caucasian.

The percentage  of students are African American is 30%, and the percentage are Caucasian is 45%. Therefore, the percentage of students are not African American or Caucasian is;

100% - 30% - 45% = 25%

So, 25% of  the students in the aerobics class are Hispanic.

To find the number of students are Hispanic,  we need to calculate 25% of the total number of  students;

25% of 40 students = [tex]\frac{25}{100}[/tex] x 40 = 0.25×40=10 students
