Trigonometric Ratios
The ratios of the sides of a right triangle are called trigonometric ratios.
The longest side of the triangle is called the hypotenuse and the other two sides are the legs.
The sine ratio is defined as:
[tex]\displaystyle \sin\theta=\frac{\text{opposite leg}}{\text{hypotenuse}}[/tex]
It's required to calculate the sine of angle C. The opposite leg to angle C is 16 and the hypotenuse is 20, thus:
[tex]\displaystyle \sin C=\frac{16}{20}[/tex]
The last choice is correct
SE TIENE UNA PARED PARA ENCHAPAR DE 5 METROS DE BASE X 2 METRS DE ALTURA , Y LOS BALDOSINES PARA ENCHAPAR TIENE 25CM DE ALTURA Y 10 CM DE BASE CUANTOS BALDOSINES SE NESECITARAN PARA ENCHAPAR LA PARED
Answer:
Se necesitan 400 baldosines para cubrir la pared.
Step-by-step explanation:
Primero debemos encontrar el área de la pared:
[tex] A_{p} = b_{p}*h_{p} [/tex]
En donde:
[tex] A_{p}[/tex]: es el área de la pared
[tex]b_{p}[/tex]: es la base de la pared = 5 m
[tex]h_{p} [/tex]: es la altura de la pared = 2 m
[tex] A_{p} = 5 m*2 m = 10 m^{2} [/tex]
Ahora debemos encontrar el área de los baldosines:
[tex] A_{b} = b_{b}*h_{b} [/tex]
[tex] A_{b} = 10 cm*25 cm = 250 cm^{2}*\frac{1 m^{2}}{(100 cm)^{2}} = 0.025 m^{2} [/tex]
Si un baldosin cubre 0.025 metros cuadrados de pared, para cubrir 10 metros cuadrados necesitamos:
[tex] N_{B} = \frac{1 B}{0.025 m^{2}}*10 m^{2} = 400 [/tex]
Por lo tanto, se necesitan 400 baldosines para cubrir la pared.

A university has 40,140 students. In a random sample of 210 students, 14 speak three or more languages. Predict the number of students at the university who speak three or more languages.
Answer:
2676 students
Step-by-step explanation:
Total number of students =. 40,140
During study:
Sample size = 210
Number of samples who speak 3 or more languages = 14
Proportion who speak 3 or more languages :
14 / 210 = 0.0666666
Applying the proportion to the total. Population :
0.0666666 * total number of students
0.0666666 * 40140
= 2675.997324
= approximately 2676 students

The table shows the relationship between the diameter in kilometers of an oil spill and the time in days. A quadratic function can be used to model this relationship.
What is the best prediction of the time required for the oil spill to reach the diameter of 10 km?
A) 147 days
B) 200 days
C) 205 days
D) 233 days
Answer:
205 is my answerrrrrrrrrrr
The best prediction of the time required for the oil spill to reach a diameter of 10 km will be 147 days. Then the correct option is A.
What is a quadratic equation?The quadratic equation is given as ax² + bx + c = y. Then the degree of the equation will be 2.
The table shows the connection between the width in kilometers of an oil slick and the time in days. A capability can be utilized to show this relationship.
The equation at (2.4, 1) will be given as,
2.4 = a (1)² + b (1) + c
2.4 = a + b + c ...1
The equation at (9.4, 2) will be given as,
9.4= a (2)² + b (2) + c
9.4 = 4a + 2b + c ...2
The equation at (21.1, 3) will be given as,
21.1 = a (3)² + b (3) + c
21.1 = 9a + 3b + c ...
Solve equations 1, 2, and 3 with the calculator, then we have
a = 2.35, b = -0.05, c = 0.1
Then the equation is given as,
y = 2.35x² - 0.05x + 0.1
The best prediction of the time required for the oil spill to reach a diameter of 10 km will be
y = 2.35(10)² - 0.05(10) + 0.1
y = 235 - 0.5 + 0.1
y = 235.5
The value of y is nearer to the value of 233. Then the value of y will be 233 days.
The best prediction of the time required for the oil spill to reach a diameter of 10 km will be 233 days. Then the correct option is D.

Grandma made an apple pie. Josh and his brother Joe ate most of it and had 1/5 of it left. Then, three friends came over and shared the leftover pie. How much of the pie did each friend eat?
Answer:
1/15
Step-by-step explanation:
Total pie = x
Total pie left = 1/5x
Then, three friends came over and shared the leftover pie
How much of the pie did each friend eat?
Pie eaten by each of the three friends = leftover pie / 3 friends
= 1/5x ÷ 3
= 1/5x * 1/3
= 1/15x
Each of the three friends ate 1/15 of the pie

Helen spent 7.75 to purchase 23 snack sized bags of chips (c) and pretzels (p). Chips cost 0.25 and pretzels cost 0.50. How much of each type of snack did she get?
Answer:
15 chips and 8 pretzels
Step-by-step explanation:
According to the problem, calculation of the given data are as follows,
Total spent = $7.75
Number of snacks = 23
Chips cost = $0.25
Pretzels cost = $0.50
Let number of chips = X
So, number of pretzels = 23 - X
So, we can calculate number of snacks by using following equation
0.25X + 0.50 ( 23 - X) = $7.75
0.25X + 11.50 - 0.50X = 7.75
0.25X - 0.50X = 7.75 - 11.5
-0.25X = -3.75
X = -3.75 ÷ -0.25 = 15
Hence, Number of chips = 15
Number of Pretzels = 23 - 15 = 8
