Answer:

Part A) The length of rectangle is [tex]3x[/tex] [tex]cm[/tex]

Part B) The perimeter of the square is [tex]3x[/tex] [tex]cm[/tex]

Part C) [tex]20[/tex] [tex]cm[/tex]

Part D) [tex]39[/tex] [tex]cm^2[/tex]

Step-by-step explanation:

Part A) Find the length of the rectangle

we know that

The perimeter of rectangle is equal to

[tex]P=2(L+W)[/tex]

we have

[tex]P=8x[/tex] [tex]cm[/tex]

[tex]W=x[/tex] [tex]cm[/tex]

Part B) Find the perimeter of the square

we know that

The perimeter of a square is

[tex]P=4b[/tex]

The measure of angle L is 52

Step-by-step explanation:

Mathematically, in a triangle, the sum of the angles equal 180

So in this case;

J + K + L = 180

So therefore;

8x + 6 + 2x + 2 + 4x + 4 = 180

8x + 2x + 4x + 6 + 2 + 4 = 180

14x + 12 = 180

14x = 180 -12

14x = 168

x = 168/14

x = 12

So to get the measure of angel L, we simply substitute the value x in the equation for L

From the question, L = 4x + 4

So therefore L = 4(12) + 4 = 48 + 4 = 52

Triangle is a two-dimensional figure which has three sides and the sum of the three angles is equal to 180 degrees.

The value of x is 17.

What is a triangle?

It is a two-dimensional figure which has three sides and the sum of the three angles is equal to 180 degrees.

Example:

Triangle ABC:

m∠A + m∠B + m∠C = 180

We have,

ΔHIJ

m∠H = x - 1

m∠I = 2x + 5

m∠J = 7x + 6

We know that,

The sum of the angles of the triangle is 180 degrees.

m∠H + m∠I + m∠J = 180

(x - 1) + (2x + 5) + (7x + 6) = 180

x - 1 + 2x + 5 + 7x + 6 = 180

10x + 10 = 180

Take 10 common.

10 (x + 1) = 180

Divide both sides by 10.

x + 1 = 180/10

x + 1 = 18

Subtract 1 on both sides.

x = 18 - 1

x = 17

Thus,

If in ΔHIJ,

m∠H = x - 1

m∠I = 2x + 5

m∠J = 7x + 6.

The value of x is 17.

f(n)=−48⋅(-¼)^n. Complete the recursive formula of f(n)
f(1)=
f(n)=f(n-1)⋅

Answers

The function f(n)=−48⋅(-¼)^n is a geometric sequence

The recursive definition of f(n) is f(1) = 12; f(n) = f(n - 1) . -¼

How to determine the recursive formula of f(n)

The function is given as:

f(n)=−48⋅(-¼)^n

Calculate f(1)

f(1)=−48⋅(-¼)^1

This gives

f(1) = 12

Calculate f(2)

f(2)=−48⋅(-¼)^2

This gives

f(2) = -3

Calculate the common ratio (r)

r = f(2)/f(1)

So, we have:

f = -3/12

Simplify

r = -1/4

Recall that: r = f(2)/f(1)

This gives

-1/4 = f(2)/f(1)

Make f(2) the subject

f(2) = -1/4* f(1)

Express 1 as 2 - 1

f(2) = -1/4* f(2 - 1)

Substitute 2 for n

f(n) = -1/4* f(n - 1)

Rewrite as:

f(n) = f(n - 1) . -¼

Hence, the recursive definition of f(n) is f(1) = 12; f(n) = f(n - 1) . -¼

If Kelly's mom is 35, it will take her 15 more years to become 50. Make an equation to represent this.

[tex]35 + 15 = 50[/tex]

Next, you want to add 15 to Kelly's age because for each year her mom ages, she ages for that same number of years.

[tex]13 + 15 = 28[/tex]

________________________________________________________

For the second problem, we just do an inverse of the problem. If Kelly is 13 and her mom is 35, how long will it take Kelly to become 50? How old will her mom be?

It would take Kelly 37 more years to become 50, because 37 + 13 = 50

Now that we have found the number of years remaining, add her mother's age by the remaining years left, r

There are yellow counters and black counters in a bag in the ratio 3:1

21 yellow counters are removed and the ratio becomes 5:4

Work out how many black counters there are in the bag.

Answers

Answer:

12 black counters

Step-by-step explanation:

Let the yellow counters be represented by 'y' and black counters by 'b'.

Originally

y : b = 3 : 1

After removing 21 counters

y - 21 : b = 5 : 4

Taking the first ratio, equate it to b.

y/b = 3b = y/3

Now, substitute for 'b' in the second ratio.

y - 21 / (y/3) = 5/43 (y - 21) / y = 5/412 (y - 21) = 5y12y - 252 = 5y7y = 252y = 36 yellow counters

Now, to find b :

b = y/3b = 36/3b = 12 black counters

Answer:

Step-by-step explanation:

Given ratio

yellow : black = 3 : 1

⇒ yellow : black = [tex]3x : x[/tex]

If 21 yellow counters are removed and the ratio becomes 5 : 4

[tex]\implies \textsf{yellow - 21: black = 5 : 4}[/tex]

[tex]\implies (3x - 21):x=5:4[/tex]

[tex]\implies \dfrac{3x - 21}{x}=\dfrac54[/tex]

[tex]\implies 4(3x - 21)=5x[/tex]

[tex]\implies 12x-84=5x[/tex]

[tex]\implies7x=84[/tex]

[tex]\implies x=12[/tex]

Substituting [tex]x=12[/tex] into the original ratio:

[tex]\implies \textsf{yellow : black} =3(12) : (12)=36:12[/tex]

So the total number of black counters = 12
