Answer:

c(t)=115(1.04)^t

Step-by-step explanation:

algebraic rule to determine the cost, c(t), of the shoes after t years is:

c(t)=115(1.04)^t

inflation means a current dollar buy less in the future. example the price of shoes next two years will be :

115(1.04)^2=124.384 dollars

An algebraic rule to determine the cost, c(t), of the shoes after t years is [tex]c(t)=115(1.04)^t[/tex].

Functions are the fundamental part of the calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.

Given that, a pair of athletic shoes costs $115.

The inflation rate remains constant at 4%.

Let the cost, c(t), of the shoes after t years.

So, the function is [tex]c(t)=115(1.04)^t[/tex]

Therefore, an algebraic rule to determine the cost, c(t), of the shoes after t years is [tex]c(t)=115(1.04)^t[/tex].

Answer:

x = 62°, y = 103°

Step-by-step explanation:

Supplementary Angles

Two angles are called supplementary when their measures add up to 180 degrees.

The image shows two pairs of supplementary angles. We have to find the value of the unknown variable.

The first drawing shows supplementary angles x and 118°. They must satisfy the equation:

x + 118° = 180°

Subtracting 118°:

x = 180° - 118°

x = 62°

From the second drawing, we set up the equation:

y + 77° = 180°

Subtracting 77°:

y = 180° - 77°

y = 103°

Answer:

0.625 = 62.5% probability that part B works for one year, given that part A works for one year.

Step-by-step explanation:

We use the conditional probability formula to solve this question. It is

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]

In which

P(B|A) is the probability of event B happening, given that A happened.

[tex]P(A \cap B)[/tex] is the probability of both A and B happening.

P(A) is the probability of A happening.

The probability that part A works for one year is 0.8 and the probability that part B works for one year is 0.6.

This means that [tex]P(A) = 0.8, P(B) = 0.6[/tex]

The probability that at least one part works for one year is 0.9.

This means that: [tex]P(A \cup B) = 0.9[/tex]

We also have that:

[tex]P(A \cup B) = P(A) + P(B) - P(A \cap B)[/tex]

So

[tex]0.9 = 0.8+0.6 - P(A \cap B)[/tex]

[tex]P(A \cap B) = 0.5[/tex]

Calculate the probability that part B works for one year, given that part A works for one year.

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.5}{0.8} = 0.625[/tex]

0.625 = 62.5% probability that part B works for one year, given that part A works for one year.

Answer: 1/40

Step-by-step explanation:

The equivalent value of the fraction is A = 1/40

Given data ,

Let the equation be represented as A

Now , the value of A is

Let the first fraction be p

Let the second fraction be q

Now , A = p/q

when the value of p = 1/8

And , when the value of q = 5

On simplifying the equation , we get

A = ( 1/8 ) / 5

So , the left hand side of the equation is equated to the right hand side by the value of ( 1/8 ) / 5

A = ( 1/8 ) / 5

A = ( 1/8 ) ( 1/5 )

On simplifying , we get

A = 1/40

A = 0.025

Therefore , the value of A = 1/40 = 0.025

Hence , the fraction is A = 1/40

Answer:

The discount was 38.04%

Step-by-step explanation:

Given that:

Original cost of pair of shoes = $184

Discounted cost of shoes = $114

Difference = 184 - 114

Difference = $70

Discount percent = [tex]\frac{Difference}{Original\ price}*100[/tex]

Discount percent = [tex]\frac{70}{184}*100[/tex]

Discount percent = 0.3804 * 100

Discount percent = 38.04%

Hence,

The discount was 38.04%

Answer:

First evening: 8 phone calls

Second evening: 60 phone calls

Third evening: 15 phone calls

Step-by-step explanation:

third evening: x

second evening: 4x

first evening: x - 7

x + 4x + x - 7 = 83

6x = 90

x = 15

First evening: x - 7 = 15 - 7 = 8

Second evening: 4x = 4(15) = 60

Third evening: x = 15

Answer:

Step-by-step explanation:

The options are :

A. x + 30 < 3x

B. x - 5 < 2x - 35

C. x divided by 4 < x - 12

D. 2x < x + 22

Option (A) :

x + 30 < 3x

Put x = 20 on both sides

LHS = 20 + 30 = 50

RHS = 3(20) = 60

50<60

The option is correct.

Option (B) :

x - 5 < 2x - 35

Put x = 20 on both sides

LHS = x-5 = 20-5 = 15

RHS = 2x - 35  = 2(20) -35 = 5

15<5

The option is incorrect.

Option (C) :

x/4 < x - 12

Put x = 20 on both sides

LHS = 20/4 = 5

RHS = x - 12 = 20-12 = 8

5<8 (correct)

Option (D) :

2x < x + 22

Put x = 20 on both sides

LHS = 2x = 2(20) = 40

RHS = x+22 = 20 + 22 = 44

40<44

It is true. The option is correct.

Hence, option A, B and D are correct.
