Find the area of this circle. Use 3 for π.
A = πr2
[?] ft2

Answer:

Answer:

You would end at (3, 3).

Explanation:

You would plot your first mark at 3 on a typical xy graph because the first number in ()'s is always x (horizontal line).

Second, because your second mark is y (vertical line), you would plot -2 on the vertical axis.

Your y plot would be 5 more than -2 because you're traveling up five units, giving you (3, 3).

If the dimension of the rectangular prism will be (4, 8, 16), (2, 8, 32), and (2, 4, 64). Then the surface area will be 448, 672, and 784 square units respectively.

A closed solid with two parallel rectangular bases joined by a rectangle surface is known as a rectangular prism.

You work for a cereal company that is looking to design some new boxes for their cereal.

The cereal is sold in the size of 512 cubic units.

You will be designing three rectangular prisms with unique dimensions.

The possible dimension of the rectangular prism will be

Volume = 512

Volume = 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2

Then we have

{(4, 8, 16), (2, 8, 32), (2, 4, 64)}

Then the surface area will be

If the dimension is (4, 8, 16). Then the surface area will be

Surface area = 2(4x8 + 8x16 + 16x4)

Surface area = 448 square units

If the dimension is (2, 8, 32). Then the surface area will be

Surface area = 2(2x8 + 8x32 + 32x2)

Surface area = 672 square units

If the dimension is (2, 4, 64). Then the surface area will be

Surface area = 2(2x4 + 4x64 + 64x2)

Surface area = 784 square units

Answer:

50° and 40°

Step-by-step explanation:

complementary angles sum to 90°

80% = [tex]\frac{80}{100}[/tex] = 0.8

let the 2 angles be x and 0.8x , then

x + 0.8x = 90

1.8x = 90 ( divide both sides by 1.8 )

x = 50

0.8x = 0.8 × 50 = 40

the 2 angles are 50° and 40°

The expected value of the winnings from a game that has the following payout probability distribution is 2.3

In statistics and probability analysis, the expected value is calculated by multiplying each of the possible outcomes by the likelihood each outcome will occur and then summing all of those values.

To calculate the expected value ,

we have to multiply each of the given probability by the individual payout value and then add the following answers

So, expected value

=0(0.45) + 2(0.3) + 4(0.1) + 8(0.1) + 10(0.05)

=0+0.6+0.4+0.8+0.5

= $2.3

Hence, the expected value is 2.3

Answer: Without replacing

Step-by-step explanation:

If you don't replace the first red marble, it decreases the number of red marbles in the mix, making the proportion of blue marbles relatively larger. For example, if there were 5 red and 5 blue marbles, there would be a 50% chance of drawing a blue marble. If the red drawn is not replaced, there is a 5/9 chance of drawing a blue marble, or a 55% chance of drawing one.

Answer:

720

Step-by-step explanation:

A polygon with 6 angles is called a hexagon

To find the sum of interior angles, we use the following formula:

(n-2)*180 (n is the number of angles)

4*180 = 720

Answer:

∠ A = 56°

Step-by-step explanation:

the sum of the 3 angles in a triangle = 180°

sum the 3 angles and equate to 180

2x + 3x + 40 = 180

5x + 40 = 180 ( subtract 40 from both sides )

5x = 140 ( divide both sides by 5 )

x = 28

then

∠ A = 2x = 2 × 28 = 56°

Answer:

(x - 6)(x - 3)

Step-by-step explanation:

x² - 9x + 18

consider the factors of the constant term (+ 18) which sum to give the coefficient if the x- term (- 9 )

the factors are - 6 and - 3 , since

- 6 × - 3 = + 18 and - 6 - 3 = - 9 , then

x² - 9x + 18 = (x - 6)(x - 3) ← in factored form

Answer:

(x - 3)(x - 6)

Step-by-step explanation:

x²- 9x+18

= x^2 - 6x - 3x + 18

= x(x - 6) - 3(x - 6)

= (x - 3)(x - 6).

i got a hundred on the test

Step-by-step explanation:

the surface area consists of 6 individual areas :

front and back (both are equal)

left and right (both are equal)

top and bottom

front and back are trapezoids.

the area of a trapezoid is

(base 1 + base 2)/2 × h

the bases are the 2 parallel sides.

in our case the area of one trapezoid is

(5 + 19)/2 × 12.1 = 145.2 ft²

front and back together then are 290.4 ft².

left and right are 8×14 rectangles:

8×14 = 112 ft²

together they are 224 ft².

the bottom is a 5×8 rectangle :

5×8 = 40 ft²

the top is a 19×8 rectangle :

19×8 = 152 ft²

so, the total surface area is

290.4 + 224 + 40 + 152 = 706.4 ft²

Answer:

30

Step-by-step explanation:

let unknown angle = x

cos = adjacent / hypotenuse

adjacent of ? = 13

hypotenuse = 15

cos(x) = (13/15)

==> take inverse cos of both sides

x = 30 (rounded)

Note : hypotenuse = longest side and adjacent = side thats not the hypotenuse or opposite

Answer:

3/7

Step-by-step explanation:

Probability = number of favorable outcomes/total number of possible outcomes

We know the total number of possible outcomes is 14 since there are 14 sides to the dice.

Let's find how many of those numbers are prime numbers.

2, 3, 5, 7, 11, and 13 are all the prime numbers between 1 and 14, so there are 6 favorable outcomes.

Now create the fraction then reduce.

Answer:

7.85 inches

Step-by-step explanation:

It mentions distance around the edge of the clock, which is basically another term used for arc length.

Arc Length Formula :

Arc Length = 2πr × θ/360°

Values given :

Radius (r) = 5 inches

Turning angle (θ) = 3/12 × 2π = 1/4 x 2π = π/2 = 90°

Solving :

Arc Length = 2 x 3.14 x 5 x 90/360

Arc Length = 15.7 x 0.5

Arc Length = 7.85 inches

Answer:

38 and 28

Step-by-step explanation:

let the 2 numbers be a and b

hence (a + b) = 66...................................2

adding 1 and 2

a -b + a + b = 10 + 66

2a=76

a = 38
