Malia that uses 51 yards of ribbon to make 17 bows will have to use 204 yards of ribbon to make 68 bows

To solve this problem we will use a rule of three with the problem information:

17 bows-------- 51 yards of ribbon

68 bows-------- x

Applying the rule of three we get:

x = (68 bows * 51 yards of ribbon) /17 bows

x = 204 yards of ribbon

It describes the proportionality of 3 known data and an unknown data. When you have more than 3 known facts that are involved in the proportionality, it is known as a compound rule. The rule of three is also known as a direct proportions.

The point which is located on the ray PQ as required in the task content given that the points M, N, O, P, Q, R, S are collinear is; point R.

It follows from the task content that the point which is located on the ray PQ is to be identified among the given answer choices.

Since all points given are said to be contained on a line, it can therefore be inferred that the points are collinear.

Also, by the definition of a ray; it follows that the ray PQ is one which starts from P and goes through Q and continues in the direction of Q.

Ultimately, the point which is located on such ray as described above among the answer choices is the point R.

The statements that are true about the graph of the system of linear inequalities include:

The graph of y > 3x − 4 has shading above a dashed line.

The graphs of the inequalities will intersect.

y means the shading will be above the corresponding line.

y means the shading will be below the corresponding line.

Together, the two graphs intersect the entire y-axis. Jointly, they only intersect the y-axis on the interval -4 < y < 1.

Therefore, the graph of y > 3x − 4 has shading above a dashed line and thee graphs of the inequalities will intersect.

3y = 5x - 24

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

given

3y = 5x + 2 ( divide through by 3 )

y = [tex]\frac{5}{3}[/tex] x + [tex]\frac{2}{3}[/tex] ← in slope- intercept form

with slope m = [tex]\frac{5}{3}[/tex]

• Parallel lines have equal slopes , then

y = [tex]\frac{5}{3}[/tex] x + c ← is the partial equation of the parallel line

to find c substitute (6, 2 ) into the partial equation

2 = 10 + c ⇒ c = 2 - 10 = - 8

y = [tex]\frac{5}{3}[/tex] x - 8 ← equation in slope- intercept form

multiply through by 3 to clear the fraction

3y = 5x - 24 ← equation of parallel line

Juan multiplied the bases together, and added the power together, therefore, his solution is wrong.

Power is the result of multiplying same number for n number of times. Power is typically expressed by a base number and an exponent. The base number indicates the number being multiplied. The exponent, which is a little number printed above and to the right of the base number, indicates the number of times the base number is multiplied.

The correct solution,

3² ∙ 9⁴

= 3² ∙ (3²)⁴

= 3²  ∙ 3⁸

= 3¹⁰

Hence, Juan multiplied the bases together, and added the power together, therefore, his solution is wrong.

The integers are 14 and 16.

Let the integers be represented by x and x+2.

It was stated that the consecutive even integers such that 6 times the smaller integer is 36 more than 3 times the larger integer.

This will be:

6(x) = 3(x + 2) + 36

6x = 3x + 6 + 36

6x = 3x + 42

6x - 3x = 32

3x = 42

The function of domain is X∈R and the range is [tex]\[\left\{ {f \in \mathbb{R}:f \le \frac{1}{4}(1 + 4\sqrt 2 )} \right\}\].[/tex]

The given function is  [tex]\[f\left( x \right) = \sqrt {2 - x - {x^2}} \][/tex]

Domain: The domain of a function is the set of input or argument values for which the function is real.

Use commutative properties to reorder the terms

[tex]\[f(x) = \sqrt { - x + 2} - {x^2}\][/tex]

Separate the function into parts to determine the domain of each part

[tex]\[f\left( x \right) = \sqrt { - x + 2} \]=-x+2= x^{2}[/tex]

Domain is XR (all real numbers)

The function has no undefined points nor domain constraints. Therefore, the domain is X∈R.

Range: The set of values of the dependent variable for which a function is defined

Range of [tex]\[\left\{ {f \in \mathbb{R}:f \le \frac{1}{4}(1 + 4\sqrt 2 )} \right\}\][/tex]

Combine the ranges of all domain intervals to obtain the function range.

We need to know about the concept of compound interest to solve the given problem. The minimum interest rate that Harry needs to meet his need is 11.4%

Compound interest can be described as the interest that you earn on both the principal amount and the interest earned. In this question it is said that the bank offers annual interest compounded monthly, we will be using a formula to solve this problem. Since Harry has 21350 EUR we will take that as the principal amount and the minimum amount that he needs is 30000 EUR we will consider this to be the final amount at the end of 3 years. We need to find out the rate of interest that the bank offers.

A=P[tex](1+\frac{r}{12} )^{12t}[/tex] where A is amount, P is principal, r is the rate of interest and t is time period.

P=21350 EUR

A=30000 EUR

t=3

30000=21350[tex](1+\frac{r}{12}) ^{36}[/tex]

[tex]\frac{600}{427} =(1+\frac{r}{12}) ^{36}[/tex]

1+[tex]\frac{r}{12}[/tex]=1.00949

r/12=0.00949

r=0.1139

r=11.4%

Therefore we found that the minimum rate of interest Harry requires to meet his needs is 11.4%

a) for given functions f(x) = 8x and g(x) = 12x + 3,

(f g)(x) = 96x² + 24x

b) for functions f(x)= 14 and g(x)= 3 - 12x,

f(x) • g(x) = 42 - 168x

In this question, we have been given two functions.

We need to find the given function.

a) f(x) = 8x and g(x) = 12x + 3

To find (f g)(x)

We know that, the product of functions f(x) and g(x) is:

(f g)(x) = f(x) . g(x)

(f g)(x) = (8x) (12x + 3)

(f g)(x) = 96x² + 24x

So, for given functions f(x) = 8x and g(x) = 12x + 3,

(f g)(x) = 96x² + 24x

b) f(x)= 14 and g(x)= 3 - 12x

To find f(x) • g(x)

f(x) • g(x) = (14) . (3 - 12x)

f(x) • g(x) = 42 - 168x

So, for functions f(x)= 14 and g(x)= 3 - 12x,

f(x) • g(x) = 42 - 168x

Therefore, a) for given functions f(x) = 8x and g(x) = 12x + 3,

(f g)(x) = 96x² + 24x

b) for functions f(x)= 14 and g(x)= 3 - 12x,

f(x) • g(x) = 42 - 168x

When Mr. Johnson earns $5.40 an hour. One week, he worked 40 hours and 2 hours overtime, If he is paid time and one-half for overtime then the total amount he earned is $232.2

Given,

The amount he earns in an hour = $5.40

Total number of hours he worked =40 hours

The amount he earns = 5.40×40 = $216

Overtime hours = 2 hours

Overtime payment per hour= 5.40×1.5= $8.1

The amount he earns for overtime = 2×8.1= $16.2

The total amount he earned = 216+16.2= $232.2
