Use a proportion. 7/10 = x/25. Multiply 10 by 2.5 to get 25. Similarly, multiply 7 by 2.5 to get 17.5. 17 1/2 pages.

Answer: She can read 17 and a half page in 25 minutes.

Step-by-step explanation:

We assume that the number of pages is directly proportional to the number of minutes taken to read them.

Given : Adrianna can read 7 pages in 10 minutes.

Rate of reading= $\dfrac{\text{Number of pages}}{\text{Time}}=\dfrac{7}{10}$ (1)

Let x denotes the number of pages she read in 25 minutes.

Rate of reading = $\dfrac{x}{25}$ (2)

From (1) and (2) , we have

$\dfrac{x}{25}=\dfrac{7}{10}$ [in direct variation ration remains constant.]

$x=\dfrac{7\times25}{10}=\dfrac{175}{10}=17\dfrac{1}{2}$

Hence, She can read 17 and a half page in 25 minutes.

9. Given the point (6,-8) values of the six trig function.

lozanna [386]

Answer:

Here's what I get.

Step-by-step explanation:

9. (6, -8)

The reference angle θ is in the fourth quadrant.

∆AOB is a right triangle.

OB² = OA² + AB² = 6² + (-8)² = 36 + 64 = 100

OB = √100 = 10

$\sin \theta = \dfrac{-8}{10} = -\dfrac{4}{5}\\\\\cos \theta =\dfrac{6}{10} = \dfrac{3}{5}\\\\\tan \theta = \dfrac{-8}{6} = -\dfrac{4}{3}\\\\\csc \theta = \dfrac{10}{-8} = -\dfrac{5}{4}\\\\\sec \theta = \dfrac{10}{6} = \dfrac{5}{3}\\\\\cot \theta = \dfrac{6}{-8} = -\dfrac{3}{4}$

10. cot θ = -(√3)/2

The reference angle θ is in the second quadrant.

∆AOB is a right triangle.

OB² = OA² + AB² = (-√3)² + (2)² = 3 + 4 = 7

OB = √7

$\sin \theta = \dfrac{2}{\sqrt{7}} = \dfrac{2\sqrt{7}}{7}\\\\\cos \theta = \dfrac{-\sqrt{3}}{\sqrt{7}} = -\dfrac{\sqrt{21}}{7}\\\\\tan \theta = \dfrac{2}{-\sqrt{3}} = -\dfrac{2\sqrt{3}}{3}\\\\\csc \theta = \dfrac{\sqrt{7}}{2} \\\\\sec \theta = \dfrac{\sqrt{7}}{-\sqrt{3}} = -\dfrac{\sqrt{21}}{3}\\\\\cot \theta = -\dfrac{\sqrt{3}}{2}$

El agua de una psicina alcanza 250 cm de altura. Si la estatura de pablo es 1520 mm dentro de la piscina sin que el agua lo cubr

Andrews [41]

Respuesta:

Pablo se cubrirá de agua si se para en la piscina

Explicación paso a paso:

El nivel del agua en la piscina = 250cm.

Altura de Pablo = 1520 mm

Para saber si pablo podría pararse en la piscina sin estar cubierto de agua, necesitamos determinar la altura de Pablo en centímetros.

Convertir la altura de Pablo de milímetro a centímetro;

1 mm hasta 0,1 cm

1520 mm = (1520 * 0,1) = 152 cm

Por lo tanto, pablo mide 152 cm.

Esto significa que la altura del agua en la piscina es mayor que la altura de Pablo y esto lo cubrirá el agua si se para en la piscina.

Help<br> 1<br> A /<br> 7 (x + 2) -5 = 30

DaniilM [7]

Answer:

x = 3

Step-by-step explanation:

Given

7(x + 2) - 5 = 30 ( add 5 to both sides )

7(x + 2) = 35 ( divide both sides by 7 )

x + 2 = 5 ( subtract 2 from both sides )

x = 3
