Step-by-step explanation:

A=1

4πd2=1

4·π·42≈12.56637cm²

Answer:

area of a circle with a diameter of 4cm=π(d/2)²

=π(4/2)²=π2²=4π cm ² is your answer or 4×3.16=12.48 cm²

Step-by-step explanation:

Answer:

784000J or 784KJ

Step-by-step explanation:

Kinetic energy (KE) can be represented with the formula

KE = 1/2(MV²)

where

M = Mass of object (Kg) =2000kg

V = velocity or speed of object in metre per second (m/s or ms^-1) = 28m/s

therefore

KE = 1/2(mv²) becomes

KE = (1/2) X 2000 X 28 X 28

KE = 784000Joules

Answer:

x = 70°

Step-by-step explanation:

the interior angle which is supplemental to 140° is 40°

the sum of the interior angles of any triangle is 180°

so:

180° = 40° + 2x

subtract 40° from each side of the equation:

2x = 140°

x = 70°

Answer:

[tex]m = 3 \sqrt{12} [/tex]

[tex]n = 6[/tex]

Step-by-step explanation:

n=1/2 of 12 according to the rule:

right triangle the side opposite the 30 degree angle is half the length of the hypotenuse.

so n=12/2=6

and now we will need Pythagorean theorem : the sum of the squares on the legs of a right triangle is equal to the square on the hypotenuse (the side opposite the right angle)—or, in familiar algebraic notation, a2 + b2 = c2.

so

[tex] {m}^{2} + {n}^{2} = {12}^{2} [/tex]

now lets put numbers on formula

[tex] {m}^{2} + {6}^{2} = {12}^{2} [/tex]

from this formula m=

[tex]m = \sqrt{ {12}^{2} - {6}^{2} } = \sqrt{144 - 36} = \sqrt{108} = 3 \sqrt{12} [/tex]

Answer:

the banana cost per kg is 6 and for orange it is 4

Step-by-step explanation:

The computation is shown below:

Let us assume the banana be x

And, the oranges be y

Now according to the question

There would be two equations

32x + 86y = 536.......(1)

96x + 52y = 784.........(2)

Now multiply by 3 in equation 1

96x + 258y = 1,608

96x + 52y = 784

258y - 52y = 1608 - 784

206y = 824

y = 4

And, the x would be

32x + 86(4) = 536

32x + 344 = 536

x = 6

Hence, the banana cost per kg is 6 and for orange it is 4

Answer:

to find V in this equation

4 = -6 + V

V = 10

hope it helps

Answer:

V would have to be equal to 10

Step-by-step explanation:

this is because you need something greater than 6 to get back to zero and then you need something to give you four more, so six plus four is equal to ten

Answer:

8

Step-by-step explanation:

40 ÷ 5 = 8

56 ÷ 7 = 8

so then just divide 64 by the one we know, which is 8

64 ÷ 8 = 8

Answer:

Step-by-step explanation:

1/2 (p/11)

slash is the dividing sign

Answer:

( p ÷ 11) ÷ 2

Or

1/2 (p ÷ 11)

Step-by-step explanation:

Half the quotient of p and 11

"the quotient of p and 11" signifies that you have to divide p by 11. And "half the.." signifies that you have to divide the quotient of p/11 in half

Answer:

8y^3 - 1

I have made it in above picture

Answer:

Step-by-step explanation:

   (2y - 1) × (4y² + 2y + 1) =

= 2y×4y² - 1×4y² + 2y×2y - 1×2y + 2y×1 - 1×1 =

        = 8y³ - 4y² + 4y² - 2y + 2y - 1 =

            = 8y³ - 1

Answer:

3.75 of blue mixed with 12.5 of white is the correct answer

Step-by-step explanation:

We know the blue and white paints are a 1.5 : 5 ratio, and if we have a total of  16.25 by  1.5 by 5.  

1.5 * 2.5 = 3.75

------------------------

5 * 2.5 = 12.5

SO blue is 3.75 and white is 12.5

Answer:

blue is 3.75 and white is 12.5

Step-by-step explanation:

Answer:

130.2 yd²

Step-by-step explanation:

Area of polygon using the length of the side, s, the apothem, a, and the number of sides, n.

A = san/2

A = (6.0 yd)(6.2 yd)(7)/2

A = 130.2 yd²

Answer:

Question 3: (D) All real numbers. Question 4: (B) y > 3.

Answer:

it is a

171 degrees

Step-by-step explanation:

Answer:

171

Step-by-step explanation:

Answer:

x=5/2

Step-by-step explanation:

4x-7=8-2x

add 7 to both sides

4x=15-2x

add 2x to both sides

6x=15

6/6x=15/6

x=5/2

(for the last part, i just simplify the fraction. 3 goes into 15 and 6)

Answer:

7% of $3200 is $224 or if u meant

Answer:

15 players

Step-by-step explanation:

First, you might want to exclude out how much it cost to rent a bus.

1479.25 - 800.50 = 678.75

After that, the remaining amount of money is how much money is spent altogether for the basketball player's meal, since each player had the same budget for the meal, it made the question easier.

678.75 ÷ 45.25 = 15

Answer:

Y = 2x + 4

Step-by-step explanation:

As the question said the slope is 2, so you put 2 with x.

The point you are given is (1,6), so you backtrack to X = 0, and since the slope is 2 you subtract 2 from 6. now you're at (0,4), giving you 4.
