The value of x in degrees will be x=78.46
What is trigonometry?The branch of mathematics dealing with the relations of the sides and angles of triangles and with the relevant functions of any angles.There are different angles like Cos,Sin,tan,cosec,sec and cot in the trigonometry.
It is given that:
We have the value of CosX=0.2 we will take inverse of the value 0.2 and find the angle X. after taking the cos inverse of the value 0.2 we found out the angle X=78.46
Cos X = 0.2
X = Cos¹ 0.2
X = 78.46°
Hence the value of x in degrees will be x=78.46

An amateur soccer ball is priced at
$19.50. This is 3/4ths the price of a
professional ball. What is the price of
the professional ball?
Answer: $26
Step-by-step explanation:
If $19.50 is 3/4, we need to find 4/4.
3/4 -> 0.75
4/4 -> 1
We will set up a proportion and solve.
[tex]\frac{19.5}{0.75} =\frac{x}{1}[/tex]
19.5 = 0.75x
26 = x
The professional ball is $26.
Answer:
$26
Step-by-step explanation:
19.50 = 3/4
so
to find 1/4, we do 19.50 / 3 = 6.5
6.5 = 1/4
so the price of a professional ball would be 4/4 (1 whole)
6.5 x 4 = 26
Hope this makes sense.

40=3x+x^2
How do I find the answer to this
Answer:
x = -8, x = 5
Step-by-step explanation:
This can be solved using Factorization method:
[tex] 40 = 3x + {x}^{2} \\ \\ \implies \: {x}^{2} + 3x - 40 = 0 \\ \\ \implies \: {x}^{2} + 8x - 5x- 40 = 0 \\ \\ \implies \: x({x} + 8) - 5(x + 8) = 0 \\ \\ \implies \: ({x} + 8) (x - 5) = 0 \\ \\ \implies \: ({x} + 8) = 0 \: \: or \: \: (x - 5) = 0 \\ \\ \implies \: x = - 8 \: \: or \: \: x = 5 \\ \\ x = - 8, \: \: 5[/tex]
Jonah and Tito were practicing for the upcoming track meet. Jonah finished 5 laps in 9 minutes, while Tito finished 7 laps in 11.2 minutes, each running at a steady pace. Who is running at a faster rate?
Since the unit rate of Tito is greater than that of Jonah, hence Tito is running at a faster rate
Unit ratesThe ratio of distance covered by an object to tme taken is unit rate.
Calculate the unit rate for both Jonah and Tito
For Jonah
Unit rate = 5laps/9minutes
Unit rate = 0.56 laps per minute
For Tito
Unit rate = 7laps/11.2minutes
Unit rate = 0.625laps per minute
Since the unit rate of Tito is greater than that of Jonah, hence Tito is running at a faster rate

Area:-
Length×Width12(34)408ft²Answer:
408 ft²
Step-by-step explanation:
Given that,
→ Length (l) = 12 ft
→ Breadth (b) = 34 ft
Formula we use,
→ Area of rectangle = l × b
Then the area will be,
→ l × b
→ 12 × 34
→ 408 ft²
Hence, the area is 408 ft².

The volume of the triangular prism is 108 in³
Step-by-step explanation:
Formula used
Volume of a prism = base area × height
Area of a rectangle = width × length
Area of a triangle = 1/2 × base × height
Volume of a cube = s³ (where s is the side length)
---------------------------------------------------------------------------------------------------
Question 1⇒ Volume of Figure A = (5 · 7)(2)
= 70 cm³
⇒ Volume of Figure B = (13 · 7)(2)
= 182 cm³
⇒ Total Volume = Volume of Figure A + Volume of Figure B
= 70 + 182
= 252 cm³
The first statement is false.
Rewritten statement:
The volume of figure A can be found by multiplying (5 · 7)(2).
---------------------------------------------------------------------------------------------------
Question 2⇒ Volume of rectangular prism = (15 · 15)(2)
= 450 mm³
⇒ Volume of central cube = 2³
= (2 · 2 · 2)
= 8 mm³
⇒ Total Volume = Volume of rectangular prism - Volume of cube
= 450 - 8
= 442 mm³
The third statement is false.
Rewritten statement:
The total volume of the figure is 442 mm³
---------------------------------------------------------------------------------------------------
Question 3⇒ Volume of rectangular prism = (12 · 3)(8)
= 288 in³
⇒ Volume of triangular prism = (1/2 · 12 · 6)(3)
= 108 in³
⇒ Total Volume = Volume of rectangular prism + Volume of triangular prism
= 288 + 108
= 396 in³
The second statement is false.
Rewritten statement:
The volume of the triangular prism is 108 in³

Tim is playing a game. His score in round 1 is 1.7 points, in round 2 is 5.1 points, in round 3 is 15.3 points, and it continues to increase in the same way. Is his score a geometric sequence? If so, write a recursive definition for the sequence.
The recursive definition for the geometric sequence is given as follows:
[tex]a_n = 3a_{n-1}, a_1 = 1.7[/tex]
What is a geometric sequence?A geometric sequence is a sequence in which the result of the division of consecutive terms is always the same, called common ratio q.
The nth term of a geometric sequence is given by:
[tex]a_n = a_1q^{n-1}[/tex]
In which [tex]a_1[/tex] is the first term.
The recursive definition of a geometric sequence is given by:
[tex]a_n = qa_{n-1}[/tex]
In this problem, we have that the first term and the common ratio are given, respectively, by:
[tex]a_1 = 1.7, q = \frac{15.3}{5.1} = \frac{5.1}{1.7} = 3[/tex].
Hence the recursive definition is given by:
[tex]a_n = 3a_{n-1}, a_1 = 1.7[/tex]
