In a high school orchestra, the ratio of cellos to violins is 1 to 3. There are 21 violins. Write and solve a proportion that gives the number c of cellos in the orchestra.
Answers
Answer:Number of cellos =7
Step-by-step explanation:
The ratio of cellos to violins is 1 to 3=1:3
Total ratio = 1+3=4
To find the total number of cellos and violins in the orchestrs,
Ratio of violins/ Total ratio x Total number of cellos and violins = Number of violins
3/4 x X= 21
X=21 x 4 / 3
X =7x 4 28.
Number of cellos =Ratio of cellos / Total ratio x Total number of cellos and violins
=1/4 x28
=7 cellos

La profundidad de una alberca aumenta paulatinamente desde 0.80 metros hasta 3 metros en una longitud de 10 metros cual es el angulo de inclinacion de la alberca
Answers
Answer:
El ángulo de inclinación de la alberca es aproximadamente 12.407º.
Step-by-step explanation:
Puesto que conocemos la distancia horizontal ([tex]l[/tex]) y la variación en la profundidad ([tex]h[/tex]) de la alberca, en metros, podemos emplear la siguiente razón trigonométrica para calcular el ángulo de inclinación de la alberca ([tex]\alpha[/tex]), en grados sexagesimales:
[tex]\alpha = \tan^{-1}\left(\frac{h}{l} \right)[/tex] (1)
Si sabemos que [tex]l = 10\,m[/tex] y [tex]h = 2.20\,m[/tex], entonces el ángulo de inclinación de la alberca es:
[tex]\alpha \approx 12.407^{\circ}[/tex]
El ángulo de inclinación de la alberca es aproximadamente 12.407º.

1.)Probability that exactly 3 fail
2.) Fewer Than 3 fail
Answer:
0.1026 ;
0.8623
Step-by-step explanation:
Using the binomial probability formula :
P(x =x) = nCx * p^x * (1 - p)^(n - x)
p = 0.11
1 - p = 1 - 0.11 = 0.89
n = 12
P(x = 3) = 12C3 * 0.11^3 * 0.89^0
P(x = 3) = 0.1026
Fewer Than 3
P(x < 3) = p(x = 0) + p(x = 1) + p(x = 2)
Using a binomial probability calculator :
P(x = 0) = 0.2470
P(x = 1) = 0.3663
P(x = 2) = 0.2490
(0.2470 + 0.3663 + 0.2490) = 0.8623

(PLEASE) Triangle IJK is similar to triangle LMN. Find the measure of side MN. Round your answer to the nearest tenth if necessary. Figures are not drawn to scale.
Answers
Answer:
MN = 126.31Step-by-step explanation:
ΔIJK = ΔLMN --- (given)
So,-----------------------
KI / KJ = NL / MN
19 / 40 = 60 / MN
MN = 60 × 40 / 19
MN = 126.31
The required measure of side MN will be 126.3 units.
What are Similar Triangles?Similar Triangles are defined as two triangles with the same shape, equal pair of corresponding angles, and the same ratio of the corresponding sides. The triangles that like one another but may not be exactly the same size are said to be similar triangles.
Given that triangle ΔIJK ~ ΔLMN in the question.
We know that Similar triangles with the same shape, equal pair of corresponding angles, and the same ratio of the corresponding sides.
As per the similarity rule of triangles, we can write the ratio as:
⇒ KI / KJ = NL / MN
⇒ 19 / 40 = 60 / MN
⇒ MN = 60 × 40 / 19
⇒ MN = 126.3157
Rounded to the nearest tenth to get
⇒ MN = 126.3
