Jessica is correct as one can use use the expression 5(13h + 19) to find the cost of the 1.5 hours job.

Expression simply refers to the mathematical statements which have at least two terms which are related by an operator and contain either numbers, variables, or both.

Addition, subtraction, multiplication, and division are all possible mathematical operations. As an illustration, the expression x + y has the terms x and y with an addition operator between them.

In this case, the expression is 5(13h + 19) where h = number of hours.

It should be noted that to find the value of 1.5 hours, one will slot the 1.5 into h.

Answer:

It’s 2.07 pounds/in 3

Step-by-step explanation:

1 kilogram = 2.2 × pounds, so,2.07 × 1 kilogram = 2.07 × 2.2 pounds (rounded), or2.07 kilograms = 4.554 pounds.Step 2: Convert the decimal part in pounds to ouncesAn answer like "4.554 pounds" might not mean much to you because you may want to express the decimal part, which is in pounds, in ounces which is a smaller unit.So, take everything after the decimal point (0.55), then multiply that by 16 to turn it into ounces. This works because one pound equals 16 ounces. Thus,4.55 pounds = 4 + 0.55 pounds = 4 pounds + 0.55 × 16 ounces = 4 pounds + 8.8 ounces. So, 4.55 pounds = 4 pounds and 8 ounces (when rounded). Obviously, this is equivalent to 2.07 kilograms. Step 3: Convert from decimal ounces to a usable fraction of ounceThe previous step gave you the answer in decimal ounces (8.8), but how to express it as a fraction? See below a procedure, which can also be made using a calculator, to convert the decimal ounces to the nearest usable fraction: a) Subtract 8, the number of whole ounces, from 8.8:8.8 - 8 = 0.8. This is the fractional part of the value in ounces.b) Multiply 0.8 times 16 (it could be 2, 4, 8, 16, 32, 64, ... depending on the exactness you want) to get the number of 16th's ounces:0.8 × 16 = 12.8.c) Take the integer part int(12.8) = 13. This is the number of 16th's of a pound and also the numerator of the fraction.Finalmente, 2.07 quilogramas = 4 pounds 8 3/4 ounces.A fração 12/16 não está simplificada, e ainda pode ser reduzida para 3/4 para que possamos expressar como a fração mais simples possível.In short:2.07 kg = 4 pounds 8 3/4 ounces

The student has to pay the interest of $733.73.

Option (B) is correct.

What is compound interest?

Compound interest is the interest that is calculated not only on the principal amount of a loan or investment, but also on any interest that has accumulated on the principal in previous periods. It is a way for lenders or investors to earn interest on their money over time, and it can lead to significant growth in the value of an investment or loan balance.

To calculate the interest owed on the credit card in this scenario, we can use the formula for compound interest:

A =\(P(1 + r/n)^{(nt)\)

where:

A = the total amount owed (principal plus interest)

P = the initial principal amount ($3,200 in this case)

r = the annual interest rate as a decimal (0.1299 in this case)

n = the number of times the interest is compounded per year (continuous compounding in this case)

t = the time period in years (16/12 = 4/3 years in this case)

Substituting in these values, we get:

A =\(3200(1 + 0.1299/1)^{(1/3*4)\)

Simplifying this expression gives:

A = 3200(1.0363)¹'³³³

A = $3,933.73

So the total amount owed after 16 months is $3,933.73. To find the amount of interest owed, we subtract the initial principal amount of $3,200:

Interest = $3,933.73 - $3,200

Interest = $733.73

Therefore, the student has to pay the interest of $733.73.

Option (B) is correct.

Step-by-step explanation:

Answer:

0.004

Step-by-step explanation:

Since 4/10 is 0.4 and 4/100 is 0.04, 4/1000 must be 0.004

Answer:

0.004

Step-by-step explanation:

\(\frac{4}{1000}\) is basically \(4 \cdot 10^{-4\) (if you've learned scientific notation), so all you have to do is move the decimal to the left four times. That gives us

\(4.0\\0.4\\0.04\\\boxed{0.004}\)

More depth:

\(10^{-4\) also equals 0.001, so \(4 \cdot 0.001 = \boxed{0.004.}\)

Parent function is f(x) = 2ˣ. Graph of function f(x) = (1/2)2ˣ + 3 is attached below.

The exponential function contains an exponent. It has a constant as its base and a variable as its exponent, not vice versa (if a function has a variable as its base and a constant as its exponent, it is a power function)

An exponential function is a function of the form f(x) = aˣ. where "x" is a variable and "a" is a constant called the base of the function, which must be greater than 0.

Given exponential function,

f(x) = (1/2)2ˣ + 3

parent function

f(x) = 2ˣ

Putting x = 0

y = (1/2)2⁰ + 3

y = 7/2

point is (0, 7/2)

Putting x = 1

y = (1/2)2¹ + 3

y = 4

point is (1, 4)

Putting x = 2

y = (1/2)2² + 3

y = 5

point is (2, 5)

Graph of the function f(x) = (1/2)2ˣ + 3 can be drawn by plotting (0, 7/2), (1, 4) and (2, 5).

Hence, f(x) = 2ˣ is the parent function. Graph of the function f(x) = (1/2)2ˣ + 3 is attached below.

\(\huge\boxed{\sf r = 5}\)

Step-by-step explanation:

Given that,

7q + 35 = 7q + 7r

7q - 7q + 35 = 7q - 7q + 7r

35 = 7r

35/7 = r

5 = r

OR

\(\rule[225]{225}{2}\)

Answer:

r = 5

Step-by-step explanation:

Given statement,

→ 7(q + 5) is equivalent to (q + r)7.

Forming the equation,

→ 7(q + 5) = 7(q + r)

Now we have to,

→ Find the required value of r.

Then the value of r will be,

→ 7(q + 5) = 7(q + r)

Applying Distributive property:

→ 7(q) + 7(5) = 7(q) + 7(r)

→ 7q + 35 = 7q + 7r

Cancelling 7q from both sides:

→ 35 = 7r

→ 7r = 35

Dividing the RHS with number 7:

→ r = 35/7

→ [ r = 5 ]

Therefore, the value of r is 5.

The frequency of y=cos4x+2 using trigonometric functions is F= 2/π.

The basics of trigonometry involve angles, how to measure them, and angles-related problems. Three crucial trigonometric functions—cotangent, secant, and cosecant—can be created using the three fundamental ratios or functions which are sine, cosine, and tangent. All of the fundamental principles of trigonometry are built upon these functions.

Standard form of a cosine function, y = A cos (Bx-C) + D

Given, y = cos4x + 2

So, A = 1, B = 4, C= =0 and D = 2

Now Period = 2π/B

                    =2π/4

                    = π/2

Now we know, frequency = 1/period

                      ⇒ frequency = 1/π/2

                      ⇒ frequency = 2/π

It would take Fran and Denise (working together) approximately \(\frac{24}{7}\) hours to paint the living room.

To solve this problem, we can use the concept of "work rates."

Let's find out how much work Fran and Denise can do individually in one hour.

If Fran takes 6 hours to paint the living room alone, her work rate is \(\frac{1}{6}\) of the room per hour \((\frac{1 room}{6 hours } = \frac{1}{6}room/hour )\).

Similarly, if Denise takes 8 hours to paint the living room alone, her work rate is \(\frac{1}{8}\) of the room per hour \((\frac{1 room}{8 hours } =\frac{1}{8}room/hour )\).

When they work together, their work rates are additive.

So, their combined work rate would be:

\(\frac{1}{6} room/hour+\frac{1}{8} room/hour\)

\(=(\frac{4}{24} )room/hour + (\frac{3}{24} )room/hour\)

\(=\frac{7}{24} room/hour\)

This means that working together, Fran and Denise can paint \(\frac{7}{24}\) of the living room in one hour.

To determine the total time required for them to paint the entire room, we can invert their combined work rate:

\(\frac{(1 room) }{(\frac{7}{24}room/hour) } =\frac{24}{7}hour\)

Therefore, it would take Fran and Denise (working together) approximately \(\frac{24}{7}\) hours to paint the living room.
