Answer:

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]

=  [tex]31 \ units^2[/tex]

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:

12 quarters

Step-by-step explanation:

number of quarters ---------x

number of dimes ------------y

therefore, x + y = 37---------------times 10 both sides --------10x + 10y = 370-------equation 1

              0.25x + 0.1y = 5.5 -----times 100 both sides -------25x + 10y = 550 ------equation 2

equation 2 minus equation 1 is 25x + 10y - 10x - 10y = 550 - 370 ------ 15x = 180 -------x = 12

there are 12 quarters

Answer:

n=7

Step-by-step explanation:

6(n-3) - 2n=10

Distribute

6n - 18 -2n = 10

Combine like terms

4n -18 = 10

Add 18 to each side

4n-18+18 = 10+18

4n = 28

Divide by 4

4n/4 = 28/4

n = 7

C.

Step-by-step explanation:

Answer: Just use a calculator.

Step-by-step explanation:

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:

Step-by-step explanation:

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

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:

Midpoint is[tex](-25.15,10.2)[/tex]

Step-by-step explanation:

A line segment refers to line that has two endpoints.

Let [tex](a,b),(c,d)[/tex] be the endpoints of a line segment.

Midpoint of the line segment is given by [tex](\frac{a+c}{2} ,\frac{b+d}{2})[/tex]

Take the given points as follows:

[tex](a,b)=(-24.6,38.1)\\(c,d)=(-25.7,-17.7)[/tex]

Midpoint of a line segment [tex]=(\frac{-24.6-25.7}{2},\frac{28.1-17.7}{2})[/tex]

[tex]=(\frac{-50.3}{2} ,\frac{20.4}{2} )\\=(-25.15,10.2)[/tex]
