Answer:

It’s $17.22 repeating per foot so $17.22: 1 ft

Step-by-step explanation:

Divide $310 by 18 ft and you will get 17.22 when you divide 18 by 18 you get 1 making the two numbers $17.22 and 1ft

At 3pm, the length of the shadow of a thin vertical pole standing on level ground is the same as the height of the pole. A while

aliya0001 [1]

Answer: The height of the pole is 175.97 ( approx )

Step-by-step explanation:

Let the height of the pole is x cm,

Also, let the angle of elevation of the sun to the pole at 3 pm is $\theta$

Thus, by the question,

$tan\theta = \frac{\text{ The height of the pole}}{\text{ The height of the shadow}}$

$\implies tan\theta = \frac{x}{x}$ ( at 3pm the height of shadow = height of the pole)

$\implies tan\theta = 1$

$\implies \theta = 45^{\circ}$

Again, according to the question,

When the angle of elevation is $(\theta - 12^{\circ})$ ,

The height of shadow = x + 95,

$\implies tan(45-12)^{\circ}=\frac{x}{x+95}$

$\implies tan 33^{\circ}=\frac{x}{x+95}$

$\implies tan 33^{\circ}x + 95\times tan33^{\circ}=x$

$\implies tan 33^{\circ}x - x = - 95\times tan33^{\circ}$

$\implies -0.3505924068 x = - 61.6937213538$

$x=175.969930202\approx 175.97\text{ cm}$

Algebra 1 Grade 9

p = total # of pages

2/5p + 32 = 310 (She read 2/5 of the book, read an addition of 32 pages, and she read a total of 310 pages.) Subtract 32 on both sides

2/5p = 278 (multiply each side by 5/2 to get p by itself)

p = 695
