Dan buys a car for £700.
It depreciates at a rate of 5.5% per year.
How much will it be worth in 6 years?
Give your answer to the nearest penny where appropriate

Answers

Answer:

£469

Step-by-step explanation:

Given the following

Original cost of car = £700.

Depreciation rate = 5.5%

Depreciation amount after 1 year = 5.5% * 700

Depreciation amount after 1 year = 0.055 * 700

Depreciation amount after 6 year =6 * 38.5 =  £231

Worth after 6 years =  £700 -  £231

Worth after 6 years = £469

The correct answer is:

£498.53

Select the equation that is equivalent to the equation y-3=2(x+5)

Answers

The first option (2x - y) = -13 is correct.

Explanation:
Start out with: y-3=2(x+5)
Expand and isolate the y variable: y=2x+10+3
Add like terms: y=2x+13
To fit the answers on the MC question, move the x variable to the left side of the equation: y-2x=13
Then multiply everything by (-1) to fit the first option: 2x-y= -13

Jenny is 9 years younger than Sammie. Five years ago Sammie was 4 times older than Jennie. How old is each now?
Pls Help Need Answer By 7:00.

Answers

Jenny is 8 years old and Sammie 17 is years old.

Given that:Jenny is 9 years younger than Sammie.Five years ago, Sammie was 4 times older than Jennie.To find:

Current age of Jennie and Sammie

Calculation and Explanation.

Let the current age of Jennie be x.

Let the current age of Sammie be y.

Then from given data we have:

[tex]x = y-9\\4(x-5) = (y-5)[/tex]

We'll substitute value of x from equation 1 in equation 2:

[tex]4(y-9-5) = (y-5)\\3y = 51\\y=17[/tex]

Thus, from equation 1 and y = 17, we have:

[tex]x=y-9\\x=17-9\\x=8[/tex]

Thus, Jenny is 8 years old and Sammie 17 is years old.

Paddy and Anna each invest $2000 for 5 years.

Paddy earns simple interest at a rate of 1.25% per year.

Anna earns compound interest at a rate of r% per year.

At the end of 5 years, Paddy's investment is worth the same as Anna's investment.

Calculate the value of r.

Answers

Answer: r= 1.22

Step-by-step explanation:

Formula for amount with simple interest = [tex]P(1+rt)[/tex]

, where

P= principal value , r= rate of interest , t = time.

Given: P=  $2000, t= 5 years, r= 1.25% = 0.0125

[tex]A=2000(1+0.0125\times5)\\\\=2000(1.0625)=2125[/tex]

Formula to compute compound amount : [tex]P(1+r)^t[/tex]

[tex]=2000(1+r)^5[/tex]

When both have same worth then

[tex]2000(1+r)^5=2125\\\\\\ (1+r)^5=\dfrac{2125}{2000}\\\\\\ (1+r)^5=1.0625[/tex]

taking log on both sides , we get

[tex]5\ln (1+r)=\ln 1.0625\\\\\\ 5\ln (1+r)=0.0606246\\\\\\ \ln (1+r)=0.012125\\\\\\ 1+r=e^{0.005266}\\\\\\ 1+r=1.0122\\\\ r=0.0122\\\\ \\ r=1.22\%[/tex]

Hence, Value of r= 1.22

What are trigonometric ratios?

The sides and angles of a right-angled triangle are dealt with in Trigonometry. The ratios of acute angles are called trigonometric ratios of angles. The six trigonometric ratios are sine (sin), cosine (cos), tangent (tan), cotangent (cot), cosecant (cosec), and secant (sec).

In the given triangle JKL, JK=25, JL=7 and LK=24.

We know that, sin θ= Perpendicular/Hypotenuse

tan θ= Perpendicular/Base

A) Now, sin J=LK/JK

sin J= 24/25

B) tan J=LK/JL

tan J=24/7

C) sin K=JL/JK

sin K=7/25

D) tan K=JL/LK

tan K=7/24

Therefore, from the options equation A and D are correct answers.

Write an equation in point-slope form for the line that passes through each point with the given slope (-1,-2) m= 3

Answers

Answer:

          y + 2 = 3(x + 1)

Step-by-step explanation:

The Point-Slope form of equation of a line with slope of "m" and passing through point (x₁, y₁) is:  y - y₁ = m(x - x₁)

m = 3

x₁ = -1

y₁ = -2

Therefore the equation:

                                      y - (-2) = 3(x - (-1))

                                  y + 2 = 3(x + 1)

An arithmetic sequence has a 2nd term equal to 3 and 10th term equal to -13.
Find the term of the sequence that has value -93. please answer asap.​

Answers

Answer:

50th term

Step-by-step explanation:

Second term, a + d = 3

Tenth term, a + 9d = -13

a + d = 3 (1)

a + 9d = -13 (2)

Subtract (1) from (2) to eliminate a

9d - d = -13 - 3

8d = -16

d = -16/8

d = -2

Substitute d = -2 into (1)

a + d = 3 (1)

a + (-2) = 3

a - 2 = 3

a = 3 + 2

a = 5

Find the term of the sequence that has value -93.

nth term = a + (n -1)d

-93 = 5 + (n - 1) -2

-93 = 5 + (-2n + 2)

-93 = 5 - 2n + 2

-93 = -2n + 7

-93 - 7 = -2n

-100 = -2n

n = -100/-2

n = 50

50th term = -93

Answers

Answer:

52:91

Step-by-step explanation:

To find a ratio value you need to think of it more as two numerators that together equal one whole. 4+7 is 11 so that would be the denominator. If the sum is 143, then we divide by 11 since one number is 4/11s of 143, and the other is 7/11s of 143. 143/11=13

now we multiply both:

4(13)=52

7(13)=91

Check:

91+52=143

52/91 simplifies to 4/7 or 4:7
