* A turtle and a snail start moving towards each other when they are 200 feet apart. The turtle is running at a speed of T feet per minute, and the snail is moving at a speed of S feet per minute. How soon will they meet?

Answers

Answer 1

Answer:

Answer:

200 ft 200

t = -------------------- = ---------- min

(S + T) ft/min S + T

Step-by-step explanation:

Recall that distance = (rate)(time).

The distance traveled by the turtle in t minutes is dt = (T ft/min)(t), and

the distance traveled by the snail in t minutes is ds = (S ft/min)(t). We know that ds + dt must be 200 ft.

Thus,

(S ft/min)(t) + (T ft/min)(t) = 200 ft.

The variable t, representing elapsed time, is common to both terms on the left. Thus,

200 ft 200

t = -------------------- = ---------- min

(S + T) ft/min S + T

S+T

Answer:

x = 20

Step-by-step explanation:

Turn all the numbers into fractions with the same denominator.

$6.75 = (46)/(8)$

$13(1)/(4) = (53)/(4)$ × $(2)/(2) = (106)/(8)$

$(46)/(8) + (3)/(8)x = (106)/(8)$

Subtract 6.75 from both sides

$(3)/(8)x = (60)/(8)$

Then multiply both sides by 8

$3x = 60$

Then divide both sides by 3 to get x

$(3x)/(3) = (60)/(3)$

7. The sun is at an angle of elevation of 58º. A tree casts a shadow 20 meters long onthe ground. How tall is the tree?

Answers

The height of tree is 32 meter

Solution:

Given that, The sun is at an angle of elevation of 58 degree

A tree casts a shadow 20 meters long on the ground

The sun, tree and shadow forms a right angled triangle

The figure is attached below

ABC is a right angled triangle

AC is the height of tree

AB is the length of shadow

AB = 20 meters

Angle of elevation, angle B = 58 degree

By definition of tan,

$tan \theta = (opposite)/(adjacent)$

In this right angled triangle ABC,

opposite = AC and adjacent = AB

Therefore,

$tan\ 58 = (AC)/(AB)\n\ntan\ 58 = (AC)/(20)\n\n1.6 = (AC)/(20)\n\nAC = 1.6 * 20\n\nAC = 32$

Thus height of tree is 32 meter
