Answers

Answer 1

Answer:

A)  61.93 minutes

B)  40.93 minutes

Step-by-step explanation:

Newton's law of cooling

[tex]T(t)=T_S+(T_0-T_S)e^{-kt}[/tex]

where:

T(t) is the temperature of the object at time t.[tex]T_S[/tex] is the temperature of the surrounding environment.[tex]T_0[/tex] is the initial temperature of the object.t is time.k is a constant.

Given values:

[tex]T_0[/tex] = 90°C[tex]T_S[/tex] = 20°Ct = 25 minutesT(t) = 60°C

Substitute the given values into the formula and solve for k:

[tex]\implies 60=20+(90-20)e^{-25k}[/tex]

[tex]\implies 40=70e^{-25k}[/tex]

[tex]\implies e^{-25k}=\dfrac{4}{7}[/tex]

[tex]\implies \ln e^{-25k}=\ln \dfrac{4}{7}[/tex]

[tex]\implies -25k \ln e=\ln \dfrac{4}{7}[/tex]

[tex]\implies -25k=\ln \dfrac{4}{7}[/tex]

[tex]\implies k=-\dfrac{1}{25}\ln \dfrac{4}{7}[/tex]

Part A

Given values:

[tex]T_0[/tex] = 60°C[tex]T_S[/tex] = 20°C[tex]k=-\dfrac{1}{25}\ln \dfrac{4}{7}[/tex]T(t) = 30°C

Substitute the given values into the formula and solve for t:

[tex]\implies 30=20+(60-20)e^{\frac{1}{25}t\ln \frac{4}{7}}[/tex]

[tex]\implies 10=40e^{\frac{1}{25}t\ln \frac{4}{7}}[/tex]

[tex]\implies e^{\frac{1}{25}t\ln \frac{4}{7}}=\dfrac{1}{4}[/tex]

[tex]\implies \ln e^{{\frac{1}{25}t\ln \frac{4}{7}}}=\ln \dfrac{1}{4}[/tex]

[tex]\implies {\dfrac{1}{25}t\ln \dfrac{4}{7}}\ln e=\ln \dfrac{1}{4}[/tex]

[tex]\implies {\dfrac{1}{25}t\ln \dfrac{4}{7}}=\ln \dfrac{1}{4}[/tex]

[tex]\implies t=\dfrac{\ln \dfrac{1}{4}}{{\frac{1}{25}\ln \frac{4}{7}}}[/tex]

[tex]\implies t=61.93063129...[/tex]

[tex]\implies t=61.93\;\; \sf minutes[/tex]

Part B

Given values:

[tex]T_0[/tex] = 90°C[tex]T_S[/tex] = -10°C[tex]k=-\dfrac{1}{25}\ln \dfrac{4}{7}[/tex]T(t) = 30°C

Substitute the given values into the formula and solve for t:

[tex]\implies 30=-10+(90-(-10))e^{\frac{1}{25}t\ln \frac{4}{7}}[/tex]

[tex]\implies 40=100e^{\frac{1}{25}t\ln \frac{4}{7}}[/tex]

[tex]\implies e^{\frac{1}{25}t\ln \frac{4}{7}}=0.4[/tex]

[tex]\implies \ln e^{\frac{1}{25}t\ln \frac{4}{7}}=\ln 0.4[/tex]

[tex]\implies{\dfrac{1}{25}t\ln \dfrac{4}{7}}\ln e=\ln 0.4[/tex]

[tex]\implies {\dfrac{1}{25}t\ln \dfrac{4}{7}}=\ln 0.4[/tex]

[tex]\implies t=\dfrac{\ln 0.4}{{\frac{1}{25}\ln \frac{4}{7}}}[/tex]

The value of x is 19 and the measure of angles in triangle ABC are 75°, 75° and 30° respectively.

What is a triangle?

triangle is a three-sided polygon that consists of three edges and three vertices. The most important property of a triangle is that the sum of the internal angles of a triangle is equal to 180 degrees. This property is called angle sum property of triangle.

If ABC is a triangle, then it is denoted as ∆ABC, where A, B and C are the vertices of the triangle. A triangle is a two-dimensional shape, in Euclidean geometry, which is seen as three non-collinear points in a unique plane.

The sum of ∠A + ∠B + ∠C = 180°( sum of angles in a triangle )

3x + 18 + 7x - 58 + 2x - 8 = 180°

12x -48° = 180°

12x = 228

x = 228/12

x = 19

but ∠A = 3x + 18, but x = 19

∠A = 3(19) + 18 which is 75°

Also ∠B = 7x -58

∠B = 7(19) - 58 which is 75°

∠C = 2x -8

∠C = 2(19) - 8 which is 30°

In conclusion, the value of x = 19, ∠A = 75°, ∠B = 75° ∠C = 30°

What is a confidence interval?

The confidence interval is the likelihood of a parameter of a population can be found within a range of values during a specified percentage or proportion of the time.

3. The confidence interval can be found using the formula;

[tex]CI = \overline x \pm z\cdot \dfrac{s}{\sqrt{n} }[/tex]

Where;

[tex]\overline x[/tex] = The mean of the sample = 45.07 lbs

s = The standard deviation of the sample = 0.09 lbs

n = The sample size

z = The confidence level = 1.96 at 95% confidence level

Therefore;

[tex]CI = 45.07 \pm 1.96\times \dfrac{0.09}{\sqrt{60} }[/tex]

45.0472 < μ < 45.0928

The correct option is therefore, option D

Cindy is attempting to calculate how much her car payment would be for a car that costs $27,000 to be repaid with monthly payments in 4 years at 4% APR.

Answers

Cindy's monthly payment of $609.63 will cost her $29,262.24 in 4 years at a 4% APR.

How is the total cost determined?

The total cost that Cindy will spend on the car which costs $27,000 is computed by multiplying the monthly payment by 48 months (the payment period).

The monthly payment can be determined using an online finance calculator that compounds the interest rate monthly for four years.

Cost of car = $27,000

Annual Percentage Rate (APR) = 4%

Payment period = 4 years (monthly)

N (# of periods) = 48 months (4 years x 12)

I/Y (Interest per year) = 4%

PV (Present Value) = $27,000

FV (Future Value) = $0

Results:

PMT = $609.63

Sum of all periodic payments = $29,262.24

Total Interest = $2,262.45

Thus, Cindy will spend $29,262.24 for a car that costs $27,000, if she repays monthly for 4 years.

How do you find equivalent in math?

Answers

To find equivalent expression in math is the fractions with distinct numerators and denominators but the same value are said to be equivalent fractions.

In mathematics, equivalent fractions are those with the same denominator and differing numerators.

The multiplicity of a member of a multiset in mathematics is the number of times the member appears in the multiset. The multiplicity of a root, for instance, is how many times a given polynomial has a root at a particular point.

It's crucial to understand the concept of multiplicity in order to correctly count without mentioning exceptions (for example, double roots counted twice). Thus, "counted with multiplicity" is used.

This can be highlighted by counting the number of different elements, as in "the number of separate roots," if multiplicity is disregarded. However, multiplicity is always taken into account when a set (as opposed to a multiset) is established, therefore the word "different" is not necessary.

For instance, if we simplify 5/15, we get a fraction that is equal to 1/3, which is equal to 5/15.

6x-15=90-9×

6x+9x=90+15

15x=105

×=7

Answer:

x = 7

Step-by-step explanation:

1. Distribute

3(2x - 5) = 9(10 - x)

6x - 15 = 9(10 - x)

2. Rearrange Terms

6x - 15 = 9(10 - x)

6x - 15 = 9(-x + 10)

3. Distribute

6x - 15 = 9(-x + 10)

6x - 15 = -9x + 90

4. Add 15 to both sides

6x - 15 = -9x + 90

6x - 15 + 15 = -9x  + 90 + 15

5. Simplify

Add the numbers:

6x - 15 + 15 = -9x + 90 + 15

6x = -9x + 90 + 15

Add the numbers:

6x = -9x + 90 + 15

6x = -9x + 105

6. Add 9x to both sides

6x = -9x + 105

6x + 9x = -9x + 105 + 9x

7. Simplify

Combine like terms:

6x + 9x = -9x + 105 + 9x

15x = -9x + 105 + 9x

Combine like terms:

15x = -9x + 105 + 9x

15x = 105

8. Divide both sides by the same factor

15x = 105

15x/15 = 105/15

9. Simplify

Cancel terms that are in both the numerator and denominator:

15x/15 = 105/15

x = 105/15

To put it simply, we must divide the numerator (x) by the denominator (y) to simplify it. For example, after simplifying 3 6, represent it as a fraction and identify the numerator and denominator. 3 6 can be written as 3/6. Further simplification yields 1/2.

Let's pretend the fraction is a proper fraction. The denominator is the numerator. We want to reduce the fraction to its simplest form.

a) Use Numerator =Remainder* as the denominator.

d) When the Remainder equals zero, the Divisor is the GCD (or GCF, as you say). GCF is a misnomer because it only deals with numbers. Only the term GCF applies to variables (with numerical values, as in algebraic expression).

Let us look at an example.

407/3367 is the fraction.

As evident, the numbers407 ,3367 does not appear to have share Divisors 2 or 3 or 5 or 7 or 11 from prima facie considerations. So we may take recourse of successive division method.

3367 ÷407 =Remainder 111 (quotient 8)

407 ÷ 111 =Remainder 74 (quotient 3)

111 ÷74=Remainder 37 (quotient 1)

74 ÷37 =Remainder 0 (ZERO )

Here 37 divides leaving Remainder zero. Therefore the GCD is 37

0 = -3t ( t - 3 ) - 6 ( t - 3)

-3t - 6 = 0 OR. t - 3 = 0.

t = -2. OR. t = 3.

A rectangular yard measuring 35 ft by 55 ft is bordered (and surrounded) by a fence. Inside, a walk that is 3 ft wide goes all the way along the fence. Find the area of this walk. Be sure to include the correct unit in your answer.

Answers

The area of walk is 504 square feet

Area of rectangle

The area of rectangle is define as a  product of length L and width w

calculate the area of rectangle yard

Area = L x W,  

where A equal the Area, L equals the length and W equal width.

A = 35 x 55

A= 1925 square feet

Area of the rectangular yard is 1925 square feet

From the question, we have 3ft wide goes all the way along the fence inside.

Therefore, we subtract six feet from each of the value of length ( 35) and width (55) because each side has 3feet .

Area = L x W

A = 29 x 49

A = 1421 square feet

Area of new rectangle formed by allowing for three foot walk is 1421 square feet

Area of Walk

To get the area walk;  we subtract area of new rectangular formed from area of rectangular yard

Area of Walk = Area of Rectangular yard - Area of new rectangle

Area of Walk = 1925 - 1421

Area of Walk = 504 square feet.

Therefore, the area of walk is 504 square feet.

In the end, Hill House stands for the enigmas of the human mind, whether it is "sane" or not, as well as the horror that the mind's intrinsic weirdness can arouse. Hill House is intricate, convoluted, and appears to be unknowable, just like the mind.

How does Dr Montague describe Hill House?

The history of Hill House is first described by Doctor Montague.

He asserts that "the concept of certain houses as filthy or banned" is an old one, much like the idea that some places on earth are fundamentally good and good, while others are sacred or holy.

Possibly "evil from the start," the Hill House has been uninhabitable for more than twenty years.

Instead of being malicious, Doctor Montague sees the home as sick or "deranged."

Doctor Montague learned about the rental from a previous tenant a year ago.

After researching it, he found that no renter had kept it for more than a few days.

Even finding a short-term lease, according to Montague, was challenging.
