The Diagram Shows Rectangle ABCD, With Diagnal BD. What Is The Perimeter Of Rectangle ABCS, To The Nearest

Answers

Answer 1

Answer:

Perimeter of rectangle ABCD = 32.8 unit (Approx.)

Step-by-step explanation:

Given:

Hypotenuse BD = 12 unit

Angle θ = 30°

Find:

Perimeter of rectangle ABCD

Computation:

Using trigonometry function

Sin θ = Perpendicular / Hypotenuse

Sin 30 = CD / BD

0.5 = CD / 12

Length of CD = 6 unit

Cos θ = Base / Hypotenuse

Sin 30 = BC / BD

0.866 = BC / 12

Length of BC = 10.4 unit

Perimeter of rectangle ABCD = 2[Length + Width]

Perimeter of rectangle ABCD = 2[6 + 10.4]

Perimeter of rectangle ABCD = 2[16.4]

Perimeter of rectangle ABCD = 32.8 unit (Approx.)

Answer 2

The perimeter of rectangle ABCD = 32.8 unit

We have given that,Hypotenuse BD = 12 unit

Angle θ = 30°

To find the perimeter of rectangle ABCD

Using trigonometry function

What is the formula for the sin ratio?

Sin θ = Perpendicular / Hypotenuse

Sin 30 = CD / BD

0.5 = CD / 12

Length of CD = 6 unit

What is the ratio of cos theta?

Cos θ = adjucent side / Hypotenuse

Sin 30 = BC / BD

0.866 = BC / 12

Length of BC = 10.4 unit

Formula for the perimeter of rectangle ABCD = 2(Length + Width)

Perimeter of rectangle ABCD = 2(6 + 10.4)

Perimeter of rectangle ABCD = 2(16.4)

Therefore,the perimeter of rectangle ABCD = 32.8 unit

Answer:

QS = 69

Step-by-step explanation:

Step 1

We solve using Triangle Proportionality Theorem

QR : RS = QU : UT

QR = 23

RS = ?

QU = 25

UT = 50

QR/RS = QU/UT

23/RS = 25/50

Cross Multiply

RS × 25 = 23 × 50

RS = 23 × 50/25

RS = 46

Step 2

QS = QR + RS

QR = 23

RS = 46

Hence, QS = 23 + 46

QS = 69

What is the combined area of the two bases of the following cylinder
The diameter is 12cm and the height is 15cm
A. 452.16cm^2
B. 904.32cm^2
C. 113.04cm^2
D. 226.08cm^2

Answers

D. 226.08cm^2

Since we are finding the combined area of the two bases of the cylinder, we are adding the area of the first base with the second base. The formula for the base of a cylinder is pi x r^2, since it is a circle. Since the bases are the same, we can rewrite this as 2pi x r^2.

Since the diameter is 12cm and r = 1/2 diameter, r = 6cm.

Thus, A = 2(3.1415)(6)^2 = 226.08cm^2

A. y = 500x + 8,000
B. y = -500x - 8,000
C. y = -500x + 8,000
D. y = 500x - 8,000
PLEASE HELP ME :)

Answers

Answer:

d

Step-by-step explanation:

function is a relationship between inputs where each input is related to exactly one output.

The function for the value of the motorcycle after x years.

y = 8000 - 500x

y = -500x + 8000

Option C is the correct answer.

What is a function?

function is a relationship between inputs where each input is related to exactly one output.

Example:

f(x) = 2x + 1

f(1) = 2 + 1 = 3

f(2) = 2 x 2 + 1 = 4 + 1 = 5

The outputs of the functions are 3 and 5

The inputs of the function are 1 and 2.

We have,

A new motorcycle has a value of $8,000.

Every year its value decreases by $500.

Now,

y = amount of the motorcycle

x = number of years

The function for the value of the motorcycle after x years.

y = 8000 - 500x

y = -500x + 8000

Thus,

The function for the value of the motorcycle after x years.

y = 8000 - 500x

y = -500x + 8000

Option C is the correct answer.
