Answer:
[tex]\theta \:=43.76^{\circ \:\:}[/tex]
Step-by-step explanation:
The right triangle has the hypotenuse = 18
Let 'Ф' be the missing angle
we know that
cos Ф = adjacent/hypotenuse
Here,
The adjacent to Ф = 13The hypotenuse = 18so
cos Ф = adjacent/hypotenuse
[tex]cos\:\theta \:=\frac{13}{18}[/tex]
[tex]\theta \:=\cos ^{-1}\left(\frac{13}{18}\right)[/tex]
[tex]=43.76^{\circ \:}[/tex]
Therefore, the missing angle is:

There are 30 boys in a sporting club. 20 of them play hockey and 15 play volleyball. Each boys plays at least one of the two games. Illustrate the information on a Venn diagram. How many boys play all the two games. How many boys play only one game
Answers
Answer:
5 boys play all the two games
25 boys play only one game
Step-by-step explanation:
Sets
There are two sets defined in the question: one for the boys who play hockey (H) and the other for the boys who play volleyball (V).
All the boys play at least one of the two games, so no elements are outside both sets.
There are 30 boys in total. 20 of them play hockey and 15 play volleyball. Since the sum of both numbers is greater than the total of boys, the difference corresponds to the boys who play both games.
Thus 20 + 15 - 30 = 5 boys play both games
Given that 5 boys are shared by both sets, from the 20 playing hockey, 15 play ONLY hockey. From the 15 boys playing volleyball, 10 play ONLY volleyball.
Thus 15 + 10 = 25 boys play only one game.

find the area of the trapezoid below by decomposing it into familiar shapes
Answers
Answer:
The area would be 168ft. The rectangle's area would be 144ft, and the triangle's area would be 24ft.
Rectangle:
18×8=144
Triangle:
8×3=24
Answer:
The area is 168
Step-by-step explanation:
Instead of trying to find the area of the trapezoid, you can easily figure out the area of the rectangle and triangle present in the picture.
first, multiply 18 by 8 to get the area of the rectangle. 18 x 8 = 144
Then, use the equation for area of triangle L x W/ 2 = A
(6 x 8)/2 = 24
add these 2 values.
24 + 144
168 is your final answer

As per linear equation, within 2.5 months, Rusty's hair will grow over [tex]\frac{5}{8}[/tex] inches.
What is a linear equation?"A linear equation is an equation in which the highest power of the variable is always 1. It is also known as a one-degree equation. When this equation is graphed, it always results in a straight line."
Given, the growth rate of Rusty's hair is [tex]\frac{1}{4}[/tex] inches per month.
Let, within 'x' months, her hair will grow [tex]\frac{5}{8}[/tex] inches.
Therefore, x × [tex]\frac{1}{4}[/tex] = [tex]\frac{5}{8}[/tex]

Step-by-step explanation:
16. What is P(red, yellow, blue)?
P(red, yellow, blue)= 6/16= 3/8.
4/16+ 1/16+ 1/16= 6/16= 3/8
17. What is P(orange, yellow)?
P(orange, yellow)= 1/8
1/16+1/16= 2/16= 1/8
18. P(green, blue, purple)?
P(green, blue, purple)= 5/8
7/16+1/16+2/16= 10/16= 5/8.
19. P(pink)?
P(pink)=0
There is no pink color.

What is the equation, in slope-intercept form, for the line that passes through the point (2, −3) and is perpendicular to the line represented by y = 25x + 4 ?
Answers
Answer:
The equation is;
y = (-x-23)/25
Step-by-step explanation:
The equation of a straight line can be given as y = mx + b
where m is the slope and b is the y-intercept
for y = 25x + 4
m is 25
Now, we need the slope of a line perpendicular to this,
If two lines are perpendicular, the result of the product of their slopes is -1
m1 * m2 = -1
25 * m2 = -1
m2 = -1/25
Mathematically, we have the slope in the point slope form as ;
y+3 = -1/25 (x - 2)
y = -x/25 + 2/25
y = -x/25 + 2/25 - 3
y = -x/25 -73/25

(A) Association of the given expression gives 3060.402.
(B) Conversion of the word form of number into digit form gives 1700.003.
Decimal value is defined as showing the place value of the digits in a decimal number. If any proportion of the digit is lower than 1 it would be represented after the dot right to the absolute value,
Here,
A. 3,000 + 60 + 0.4 +0.002
Simplify the above expression by the association of the numbers,
3,000 + 60 + 0.4 +0.002 = 3060.402
B. One hundred seventeen and three-thousandths
Convert words to numbers,
= 1700.003
