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

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

Step-by-step explanation:

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:

£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:

1, is So this means the answer is 81 children and 96 adults.

2,  250 $5 tickets and 100 $11 tickets were sold

Step-by-step explanation:

--- To solve this, you can use quadratics. x + y = 177 and 4x + 11y = 1380 are the equations to solve for x and y. 177 is the total amount of people who entered the fair, and 1380 is the total money earned. x is the amount of children entered, while y is the amount of adults entered. If we were to do 4(x + y = 177), the equation would become 4x + 4y = 708. Then, we minus the 2 equations together, eliminating the x so we can solve for y. So, the final equation is 7y = 672, meaning y = 96. If we bring this into the first equation, x + y = 177, we can find that x = 81.

Answer: Yes

Step-by-step explanation:

x = 9 in (9, 8)

The inequality is x is less than or equal to 9

x = 9 so the point satisfies the inequality.

Answer:

i think this is right $4.80

Step-by-step explanation:

Answer:

a = 42

Step-by-step explanation:

2a + 16 + 80 = 2a + 96

2a + 96 = 180

2a = 84

a = 42

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

From the options equation A and D are correct answers.

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.

3x+4x = 70

x = 10

There are 30 boys.

Answer:

k = 7

Step-by-step explanation:

The goal is to solve for the variable k in this problem.

To do this, we need to get k by itself!

2k + 16 = 30

Start by subtracting the 16 over from the left side to the right

2k + 16 - 16 = 30 - 16

Simplify by subtracting 16 from 16 on the left side (which is 0) and 16 from 30 on the right side (which is 14).

2k = 14

Then finish by dividing both sides by 2 to get k by itself.

[tex]\frac{2k}{2}[/tex] = [tex]\frac{14}{2}[/tex]

Simplify by dividing 2 by 2 on the left side (which is 1) and 14 by 2 on the right side (which is 7).

k = 7

Answer: 48 dollars

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:

A(-2,5)

x= -2   ,   y=5

Step-by-step explanation:

draw the lines for both equations and that will be by finding any points in the lines:

1. sub any value for x to find y in the equation (y=-x+3) :

plot the points in the graph and match them to get the first line for equation(1).

2. sub any value for x to find y in the equation (y=-3x-1) :

Now again plot the points in the same graph and match them to get the second line for equation(2).

When you finish you will have two lines drawn in a graph, the solution will be were the two points intercept, and that will be:

A(-2,5)

x= -2   ,   y=5

(note: you can check your answer by subbing the value of x in both equations and you should get the answer 5 as the value of y)
