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

Answer:

The third answer is correct

when you plug 1 into the equation

4(1)-9= -5

4(2)-9 = -1

4(3)-9= 3

Step-by-step explanation:

The sigma notation of the given series is [tex]\sum _{j=1}^5\:\left(4j-9\right)[/tex], option C is correct.

Sequence is an enumerated collection of objects in which repetitions are allowed and order matters.

The given series is -5+(-1)+3+7+11

The sigma notation of the given series is [tex]\sum _{j=1}^5\:\left(4j-9\right)[/tex]

Now let us check by plugging j values from 1 to 5

When j =1,

4(1)-9= -5

When j =2

4(2)-9 = -1

when j=3

4(3)-9= 3

Hence, the sigma notation of the given series is [tex]\sum _{j=1}^5\:\left(4j-9\right)[/tex], option C is correct.

Answer:

b)30 boys c)1425 beats

Step-by-step explanation:

Answer:

Step-by-step explanation:

b and g are the number of boys and girls, respectively.

b:g = 3:4

b = 3x, g = 4x

3x+4x = 70

x = 10

There are 30 boys.

:::::

(380 beats)/(4 minutes) = (380/4 beats)/minute = (95 beats)/minute

15 minutes × (95 beats)/minute = 1425 beats

Answer:

9.5_<w<9.25

Step-by-step explanation:

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

Current age of Jennie and Sammie

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.

Answer: 48 dollars

Step-by-step explanation:

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

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.

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

Answer:

i think this is right $4.80

Step-by-step explanation:

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

Answer:

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))

Answer:

You know that y must have to equal 0. x can be anything though.

Step-by-step explanation:

The x-axis is a straight line in the center of the y-axis where y = 0.
