A manatee surfaced for air 3 times in 120 seconds. How many seconds went by before the manatee surfaced the first time if it held its breath for the same rate?​

Answer:

C

Step-by-step explanation:

The angle 160° and the interior angle of the triangle form a straight angle

interior angle = 180° - 160° = 20°

Similarly with angle 131° and the interior angle at the top of the triangle

interior angle = 180° - 131° = 49°

The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

n is an exterior angle, hence

n = 20° + 49° = 69° → C

Answer:

13.33%

Step-by-step explanation:

First we need to find the total number of marbles

4 blue marbles+ 3 green marbles+ 7 red marbles+ 1 yellow marble= 15

The probability of a red marble = number of red marbles over the total marbles

P(red) = red/total = 7/15

We keep the marble.  There are now 6 red marbles

4 blue marbles+ 3 green marbles+ 6 red marbles+ 1 yellow marble= 14

We have 14 marbles in the bag

The probability of a blue marble = number of blue marbles over the total marbles

P(blue) = blue/total = 4/14 = 2/7

Then we multiply the probabilities together

P(red,blue0 = 7/15 * 2/7 = 2/15 =.13333333 = 13.33%

Final answer:

The probability of selecting a red marble and then a blue marble from the bag is about 13.33%.Hence, the answer is B.

Explanation:

The probability of selecting a red marble and then a blue marble from a bag that originally contains 4 blue marbles, 3 green marbles, 7 red marbles, and 1 yellow marble involves calculating the probability of two independent events.

First, the probability of selecting a red marble is the number of red marbles over the total number of marbles, so P(Red first draw) = 7/(4+3+7+1) = 7/15.

After selecting a red marble, there is one less marble in the bag, so the new total is 14, and still 4 blue marbles. The probability of then selecting a blue marble is the number of blue marbles over the new total, so P(Blue second draw) = 4/14 = 2/7.

To find the combined probability of both events happening in sequence (red then blue), we multiply the individual probabilities: P(Red then Blue) = P(Red first draw) * P(Blue second draw) = (7/15) * (2/7) = 2/15. Converting this to a percentage gives us approximately 13.33%.

The statements that correctly describe the association between variables A and B are "positive association," "negative association," "nonlinear association," "no association," and "linear association."

Positive Association: Variables A and B have a positive association when an increase in the value of variable A corresponds to an increase in the value of variable B. In other words, as A increases, B also tends to increase, and vice versa. This relationship implies a positive correlation between the two variables.

Negative Association: A negative association between variables A and B occurs when an increase in the value of variable A corresponds to a decrease in the value of variable B, and vice versa. Here, as A increases, B tends to decrease, and vice versa. This relationship signifies a negative correlation between the two variables.

Nonlinear Association: Variables A and B exhibit a nonlinear association when the relationship between them cannot be adequately represented by a straight line. Instead, their connection follows a more complex pattern, such as a curve or some irregular shape. Nonlinear associations can still be positive or negative, but they do not follow a simple linear relationship.

No Association: When there is no association between variables A and B, changes in one variable do not correspond to any predictable changes in the other. In this case, the values of A and B are independent of each other, and there is no correlation between them.

Linear Association: Variables A and B have a linear association when their relationship can be approximated by a straight line. In a linear association, a change in one variable is proportionally reflected in the other variable. This is the simplest form of association and is characterized by a constant rate of change between the variables.

The volume of a rectangular pyramid with a base of 13 inches by 12 inches and a height of 8 inches is 416 inches³, calculated using the formula V = (1/3) × base area × height.

Explanation:

To calculate the volume of a rectangular pyramid, the formula is V = (1/3) × base area × height. The base area is the length times the width of the pyramid's base, while the height is the perpendicular distance from the base to the apex. Given the dimensions of the pyramid as a base of 13 inches by 12 inches and a height of 8 inches:

Final answer:

The volume of the rectangular pyramid with a base of 13 inches by 12 inches and a height of 8 inches is 416 cubic inches, calculated using the formula V = ¼Bh.

Explanation:

To find the volume of a rectangular pyramid, you can use the formula for the volume of any pyramid, which is ¼ the base area multiplied by the height (V = ¼Bh). In this case, the base area (B) can be calculated by multiplying the length and width of the base of the pyramid. Therefore, the base area B is 13 inches * 12 inches, which equals 156 square inches. The height (h) of the pyramid is given as 8 inches.

Using the volume formula:

Base area (B) = 13 in * 12 in = 156 in²

Height (h) = 8 in

Volume (V) = ¼ * B * h = ¼ * 156 in² * 8 in

Calculation:

V = ¼ * 156 in² * 8 in

V = 1,248 in³ ´  3

V = 416 in³

Therefore, the volume of the pyramid is 416 cubic inches.

Your answer is 8

ANSWER

The water arc is 50 ft above the water approximately 42ft and 158ft from the north shore.

EXPLANATION

The water arc is modeled by the function:

[tex]y = - 0.006 {x}^{2} + 1.2x + 10[/tex]

We write this function in vertex form:

[tex]y = - 0.006 ({x}^{2} - 200x )+ 10[/tex]

[tex]y = - 0.006 ({x}^{2} - 200x + ( - 100)^{2} ) - - 0.006( - 100)^{2} + 10[/tex]

[tex]y = - 0.006 ( x- 100)^{2} ) + 60+ 10[/tex]

[tex]y = - 0.006 ( x- 100)^{2} ) +70[/tex]

The vertex of this function is at

(100,70).

This means that the water arc reached a height of 50ft.

We put y=50 and solve for x.

[tex]- 0.006 ( x- 100)^{2}+70 = 50[/tex]

[tex]- 0.006 ( x- 100)^{2} = - 20[/tex]

[tex]( x- 100)^{2} = \frac{10000}{3} [/tex]

[tex]x = 100 \pm \frac{100 \sqrt{3} }{3} [/tex]

x=42.3 or x=157.7

Hence the water arc is 50 ft above the water approximately 42ft and 158ft from the north shore.

The water arc does reach a height of 50 feet, and it is about 42.27 feet and 157.73 feet from the north shore when it is 50 feet above the water.

1.Set up the equation:

[tex]\[ -0.006x^2 + 1.2x + 10 = 50 \][/tex]

2. Simplify the equation:

Subtract 50 from both sides:

[tex]\[ -0.006x^2 + 1.2x + 10 - 50 = 0 \] \[ -0.006x^2 + 1.2x - 40 = 0 \][/tex]

3. Solve the quadratic equation:

We can use the quadratic formula

[tex]\( x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a} \), where \( a = -0.006 \), \( b = 1.2 \), and \( c = -40 \).[/tex]

[tex]\[ a = -0.006, \quad b = 1.2, \quad c = -40 \][/tex]

[tex]\[ \Delta = b^2 - 4ac \] \[ \Delta = 1.2^2 - 4(-0.006)(-40) \] \[ \Delta = 1.44 - 0.96 \] \[ \Delta = 0.48 \][/tex]

[tex]\[ x = \frac{-b \pm \sqrt{\Delta}}{2a} \] \[ x = \frac{-1.2 \pm \sqrt{0.48}}{2(-0.006)} \][/tex]

Calculate the square root of 0.48:

[tex]\[ \sqrt{0.48} \approx 0.6928 \][/tex]

  Now, find the two values of x:

[tex]\[ x_1 = \frac{-1.2 + 0.6928}{-0.012} = \frac{-0.5072}{-0.012} \approx 42.27 \] \[ x_2 = \frac{-1.2 - 0.6928}{-0.012} = \frac{-1.8928}{-0.012} \approx 157.73 \][/tex]

Therefore, the water arc reaches a height of 50 feet at approximately [tex]\( x = 42.27 \) feet and \( x = 157.73 \)[/tex] feet from the north shore.

Answer:

a=2

h=8

k=-72

Step-by-step explanation:

[tex]y = 2 {x}^{2} - 32x + 56 \\ = 2( {x}^{2} - 16x + 28) \\ = 2( {x}^{2} - 2 \times 8 x + 64 - 36) \\ = 2 {(x - 8)}^{2} - 72 \\ then \: the \: minimum \: is \: - 72 \: and \\ \: the \: x - coordinate \: of \: minimum \: is \: 8.[/tex]

The rewritten equation is 2(x-8)^2 - 100, and the x-coordinate of the minimum is 8.

A quadratic equation is a second-degree algebraic equation in x. The conventional form of the quadratic equation is ax^2 + bx + c = 0, with a and b as coefficients, x as the variable, and c as the constant component.

y = 2x^2 - 32x + 56

y = 2(x^2 - 16x + 28)

y = 2((x^2 - 16x + 64) - 36)

y = 2((x - 8)^2 - 36)

y = 2(x - 8)^2 - 72

The equation when converted in the form  y = a(x - h)^2 + k will look like  y = 2(x - 8)^2 - 72.

The minimum value of this function is y = -72 and the x-coordinate of the minimum is x = 8.

Answer:

1,206

Step-by-step explanation:

Since we'll have to deal with cubic inches (with the ball volume), we should also calculate the volume of the car in cubic inches.

We are told the car is a rectangular prism measuring 10ft x 5 ft x 3 ft.

So, in inches (12 inches/foot), we have: 120 in x 60 in x 36 in = 259,200 cu inches.

The ball is a sphere with a radius of 3 inches.

Real volume of the ball: V = (4/3) π r³

V = (4/3) π 3³ = 36 π = 113.1 cu inches

But of course, balls don't fit perfectly one next to another, like cubes, so we have to take into account the loss... the question tells us to use a factor of 190%.

So, the packing volume of a ball is 190% its real volume:

PV = 190% * 113.1 = 214.9 cu inches

Now, how many times does that fit inside the car?

259,200 / 214.9 = 1,206.14

Let's round it to 1,206, which is a possible answer.
