Subtract sides 1

[tex]3x + 1 - 1 = 64 - 1[/tex]

[tex]3x = 63[/tex]

Divide sides by

0.4166666666666666666666666666666666666666666666666666666666666666

Step-by-step explanation:

2/3 - 1/4 = 5/12

Simplify the following:

2/3 - 1/4

Hint: | Put the fractions in 2/3 - 1/4 over a common denominator.

Put 2/3 - 1/4 over the common denominator 12. 2/3 - 1/4 = (4×2)/12 - 3/12:

(4×2)/12 - 3/12

Hint: | Multiply 4 and 2 together.

4×2 = 8:

8/12 - 3/12

Hint: | Subtract the fractions over a common denominator to a single fraction.

8/12 - 3/12 = (8 - 3)/12:

(8 - 3)/12

Hint: | Subtract 3 from 8.

8 - 3 = 5:

Answer: 5/12

Convert 5/12 to decimal = 0.4166666666666666666666666666666666666666666666666666666666666666

Answer:

A. The domain of f(x) is {all real numbers}.

B. The range of f(x) is {all real numbers}

E. f(2) = 4

Explanation

Find the graph attached.

The domain of a function is the value of the input variable x for which the function f(x) exists. Given the function

f(x) = 1/2 x + 3

The function will exist on all values of x (either positive or negative).

The domain can be said to exist on all real values. If you look at the graph, we will see that the line tends to both negative infinity and positive infinity. Hence the domain can be represented according to the set notation:

DOMAIN: (-∞, ∞)

The range is the set of output value y for all input variable x. The output value y will also exist on all real values because, no matter the value of x imputed in the function, we will always get a finite value as the output. Hence the range of the function is denoted by the set notation:

RANGE:  (-∞, ∞)

Next is to get f(2).

To get f(2), we will set the input value as 2 and calculate for the output value as shown:

f(2) = 1/2(2) + 3

f(2) = 1+3

f(2) = 4

Hence the following are true of the function:

The domain of f(x) is {all real numbers}.

- The range of f(x) is {all real numbers}

- f(2) = 4

The abundance of Si-28 is 92.23%. Si-29 is 4.68% and Si-30 is 3.09%.

Answer:

The liquid will take 17.5 minutes to reach -10.5 ºC.

Step-by-step explanation:

From this statement we understand that the temperature of liquid is increased at constant rate in time, whose model is described by:

[tex]T (t) = \dot r \cdot t + T_{o}[/tex] (Eq. 1)

Where:

[tex]T[/tex] - Temperature of the liquid, measured in degrees Celsius.

[tex]\dot r[/tex] - Heating rate, measured in degrees Celsius per minute.

[tex]t[/tex] - Time, measured in minutes.

[tex]T_{o}[/tex] - Initial temperature, measured in degrees Celsius.

If we know that  [tex]\dot r = -0.60\,\frac{^{\circ}C}{min}[/tex] and [tex]T_{o} = 0\,^{\circ}C[/tex], the temperature model for the liquid is:

[tex]T(t) = -0.60\cdot t[/tex] (Eq. 2)

In addition, if [tex]T(t) = -10.5\,^{\circ}C[/tex], then time taken for the liquid to reach that temperature is:

[tex]t = \frac{-10.5}{-0.60}[/tex]

[tex]t = 17.5\,min[/tex]

The liquid will take 17.5 minutes to reach -10.5 ºC.

Answer:

098765

Step-by-step explanation:

Given:

The smaller size is 24 oz and cost $3.99.

The larger size is 64 oz and cost $6.99.

To find:

Which has the lower unit cost?

Solution:

The formula for unit cost is

[tex]\text{Unit cost}=\dfrac{\text{Total cost}}{\text{Quantity}}[/tex]

The unit cost of smaller size is

[tex]\text{Unit cost of smaller size}=\dfrac{3.99}{24}[/tex]

[tex]\text{Unit cost of smaller size}=0.16625[/tex]

The unit cost of larger size is

[tex]\text{Unit cost of larger size}=\dfrac{6.99}{64}[/tex]

[tex]\text{Unit cost of larger size}=0.10922[/tex]

It is clear that, 0.10922 is less than 0.16625.

Therefore, the unit cost of larger size is lower.

Answer:

V would be equivalent to 300 students

Step-by-step explanation:

Noting that 3 teachers already have 60 students

If we're given 15 teachers, try dividing it by the 3 teachers that we originally have.

15/3 would be 5

We would now proceed to multiply the 60 students by 5 for the total amount of students with 15 teachers.

60*5 would be 300

Your answer should be 300 students.

The correct answer is 2858.

Answer:

can we explain it

Step-by-step explanation:

Answer:

The equation is;

y = 200•0.8^x

where y is the number of bears remaining and x is the year number in particular

Step-by-step explanation:

Let us have the rate of decrease as r and we set up an exponential equation

y = I• ( 1 - r)^x

where r is the percentage decrease, I is the initial population = 200 and x is the number of years

For the population after 1 year, we have;

160 = 200( 1 -r)^x

divide both sides by 200

0.8 = (1-r)^1

0.8 = 1 - r

r = 1 - 0.8

r = 0.2

So the equation will be;

y = 200( 1 - 0.2)^x

y = 200•0.8^x
