wel swam 86 meters. Tyrel swam 53 meters.

Answer:

20.8

Step-by-step explanation:

Plug in 2.4 as n in the expression, and simplify:

12n - 8

12(2.4) - 8

28.8 - 8

= 20.8

So, the answer is 20.8

Answer:

The answer is B) 21, 34, 65

Step-by-step explanation:

21 + 34 + 65 = 120

120 divided by 3 = 40.

In order to find the mean you must add up all of the numbers in the numerical data set, then divide that by how many numbers there are. Hope this helps! :)

Since its a 45-45-90 triangle then the 2 legs are going to be the same.

Answer:

90°

Step-by-step explanation:

Always remember that the sum of all angles is 180°.

So there are two 45° angles, so just add them up and you get 90

So if you subtract 90 from 180, you get 90, and that's your answer

I believe it would be 10 : 8

Answer:

The solution of this trigonometric identity is [tex]\theta = 56.310^{\circ} \pm 180\cdot i ^{\circ}[/tex], [tex]\forall \,i\in \mathbb{N}_{O}[/tex].

Step-by-step explanation:

Let [tex]7\cdot \tan \theta - 8 = 5\cdot \tan \theta -5[/tex], we proceed to simplify the expression and solve afterwards either by algebraic or by trigonometric means:

[tex]7\cdot \tan \theta -8 = 5\cdot \tan \theta -5[/tex]

[tex]2\cdot \tan \theta = 3[/tex]

[tex]\tan \theta = \frac{3}{2}[/tex]

[tex]\theta = \tan^{-1} \frac{3}{2}[/tex]

The tangent is a trigonometric function with a period of 180°. Hence, we find that the family of angles associated with such value is:

[tex]\theta = 56.310^{\circ} \pm 180\cdot i ^{\circ}[/tex], [tex]\forall \,i\in \mathbb{N}_{O}[/tex]

Answer:

m = rise/run = 4/5.

Step-by-step explanation:

This line goes throught the "exact" grid intersections (-2, 0) and (3, 4).  As we move from the first point to the second, we see that x increases by 5 (this is the 'run') and y increases by 4 (this is the 'rise').  Thus, the slope of this line is m = rise/run = 4/5.

Answer:

50 times

Step-by-step explanation:

Total number of faces = total possible outcomes = 8

Number of 2 or 3 on spinner = required outcome = 2

Probability of obtaining a 2 or 3 = required outcome / Total possible outcomes

P(2 or 3) = 2 / 8 = 1/ 4

From 200 ; prediction for the number of 2 or 3

1/4 * 200

= 50 times

Answer: Just use a calculator.

Step-by-step explanation:

Answer:

Every prism has as many faces, and edges, as its base has sides. Thus, a prism with an octagonal (eight sided) base has eight lateral faces, and eight lateral edges. Each lateral face meets two other lateral faces, as well as the two bases. As a consequence, each lateral face is a four sided polygon.

The number of sides of the base of a prism and the number of lateral faces is equal.

A prism is a three-dimensional object with two congruent and parallel faces, called the bases and it encloses the space between the bases. Every cross-section parallel to the base of a prism is congruent to its base.

In the question, we are asked to tell the relationship between the number of sides of the base of a prism and the number of lateral faces.

We let the number of sides of the base of the prism be s, and let the number of lateral faces of the prism be f.

We know that a prism has two parallel and congruent bases and every corresponding side of the base are connected by a pane. These planes are the lateral faces of the prisms. As each corresponding pair of sides is connected by one lateral face, the number of the lateral face is equal to the number of sides of the base.

∴ The number of sides of the base = The number of lateral faces of the prism

or, s = f.

∴ We can say that the number of sides of the base of a prism and the number of lateral faces are equal.

2) -3x+10

4) -4x+10+x

Step-by-step explanation:

Use the distributive property to get rid of the parentheses.

(2 × -2x) + (2 × 5) + x

-4x + 10 +x is correct, but the x's can be combined.

(-4x + x) + 10 = -3x + 10

The mean and mean absolute deviation of this set of data will be 312. 9 and 0.19 respectively. The mean absolute deviation represents the average distance between each data value and the mean.

The average distance between each data point and the mean is the mean absolute deviation of a dataset. It offers us an indication of how variable a dataset.

Mean = 312. 9

The area of rectangle is "31 units²".

Step-by-step explanation:

The given values are:

Length of rectangle,

= [tex]\frac{21}{7}[/tex]

Width of rectangle,

= [tex]\frac{31}{3}[/tex]

As we know,

The area of rectangle is:

=  [tex]Length\times width[/tex]

On substituting the values, we get

=  [tex]\frac{21}{7}\times \frac{31}{3}[/tex]

=  [tex]\frac{217}{7}[/tex]
