3(3 × 3) First multiply inside the parenthesis;
3(9) Then multiply the last terms;
3 × 9 = 27
so your final answer is 27

Lets write this out:-

(3 × 3)3

First lets do what is in the parentheses, because we will follow PEMDAS. Then we will multiply, Lets do it:-

(3 × 3)3
(9)3
27

So, (3 × 3)3 = 27.

Hope I helped ya!! xD

A dartboard is divided into 20 sectors. Each sector is worth a point value from 1 to 20 and has shaded regions that double or

Nikitich [7]

The area of each sector is the amount of space on the sector

The area of the entire region is 6.89
The area of the double region is 0.75
The area of the triple region is 0.46

<h3>The area of the entire sector</h3>

The area of a sector is calculated as:

A = (1/2) × r^2θ

For the entire sector, we have:

θ = π/10

r = 6.625

So, we have:

A = (1/2) × 6.625^2 × π/10

Evaluate the product

A = 6.89

<h3>The area of the double region </h3>

For the double region, we have:

θ = π/10

r = 6.25

So, we have:

A = Complete sector - (1/2) × r^2θ

A = 6.89 - (1/2) × 6.25^2 × π/10

Evaluate the difference

A = 0.75

<h3>The area of the triple region </h3>

For the triple region, we have:

θ = π/10

R = 4.125

r = 3.75

So, we have:

A = (1/2) × R^2θ - (1/2) × r^2θ

A = (1/2) × 4.125^2 × π/10 - (1/2) × 3.75^2 × π/10

Evaluate the difference

A = 0.46

Hence, the area of the triple region is 0.46

Could someone help me with this?

hodyreva [135]

Step-by-step explanation:

Identity the variable:

Initial Velocity is 35.

Initial Height is 204

Final Height is 0.

What looking for the time.

So we have

$0 = - 16 {t}^{2} + (35)t + 204$

Use Quadratic Formula,

$- b± \frac{ \sqrt{b {}^{2} - 4ac} }{2a}$

A is -16, B is 35 , C is 204.

So we have

$- 35± \frac{ \sqrt{ {35}^{2} - 4( - 16)(204) } }{ - 32}$

$- 35± \frac{ \sqrt{1225 + 2240} }{ - 32}$

$- 35± \frac{ \sqrt{3465} }{ - 32}$

${35} ± \frac{ \sqrt{3465} }{ - 32}$

The positve solution is

$4.83$

So the answer is 4.83 seconds

Construct a ∆ PQR , given that PQ = 5.5 cm ,QR = 4.8 cm and PR = 4.2 cm . Write steps of construction .

Lemur [1.5K]

Answer:

Step-by-step explanation:

AT first, draw the reference line, which are given. If I take PQ as base, I won't need to draw PQ line as reference.

I took PQ(5.5cm) as base. Then, take 4.8cm in your compass by centering at point Q. Draw an arc. Then take 4.2 cm in your compass from the reference line which you have drawn and then centre at point P and draw an arc. Both the arcs will meet at one point. Then join the lines to form the Triangle PQR
