Do you know how many can in a m
AlekseyPX2 years ago
5 0

Answer:

There are 2.54 centimeters in an inch. There are 63,360 inches in a mile. So, there are 160,934 centimeters in a mile. There are 3600 seconds in an hour.

36 cm/sec is 36 times 3600 cm/hour = 129,600 cm/hour. Therefore, there are 129,600/160,934 miles per hour = 0.80529 mph

Step-by-step explanation:

hope it helps

FACTOR COMPLETELY<br><br> x^2-7x+7y-y^2
shtirl [24]

Given: {x}^{2} - 7x + 7y -  {y}^{2}

Now factoring them,

=  > (x - y)(x + y) - 7(x - y)

=  > (x - y)(x + y - 7)

Therefore, the answer to the question is (x - y)(x + y - 7)

You are standing 30 meters from a hot air balloon that is preparing to take
Lerok [7]

Answer:

The distance to the top of the balloon is approximately 33.977 meters

Step-by-step explanation:

The (horizontal) distance from the hot air balloon from the observer, <em>l</em> = 30 m

The angle of elevation to the top of the balloon, θ = 28°

With the balloon standing upright, the distance to the top of the balloon, <em>d</em>, the height of the balloon, <em>h</em> and the horizontal distance to the balloon, <em>l</em>, form a right triangle, where;

d = The hypotenuse side

l = The leg adjacent to the reference (given) angle,

h = The leg opposite to the given angle, θ

By trigonometric ratios, we have;

cos\angle X = \dfrac{Adjacent\ leg \ length}{Hypotenuse \ length}

From which we get;

cos\angle \theta = \dfrac{l}{d}

cos(28^{\circ})  = \dfrac{30 \ m}{d}

d = \dfrac{30 \ m}{cos(28^{\circ}) } \approx 33.977 \, m

The distance to the top of the balloon, <em>d </em>≈ 33.977 m

A man who is 2 meters tall stands on level ground. He is 32 meters from the base of a tree. The angle of elevation of the top of
podryga [215]

Answer:

h = 16.92 m

Step-by-step explanation:

If you mean to man horizontal line of sight  then the height of the tree is:

h = 2m + x

x is one right side and second is distance from the base of a tree 32m.

Tangence in this right triangle is:

tan 25° = x / 32 => x = 32 · tan 25° = 32 · 0.4663 = 14.92m

h = 2 + 14.92 = 16.92m

God with you!!!
