Answer:

Distance from the base of the escalator to the point on the first floor directly below the top of the escalator = 27.5 feet

Step-by-step explanation:

Given:

Length of escalator = 30 feet

Distance between the floors = 12 feet

To find the distance from base of escalator to the point on the first floor directly below the top of the escalator  we will create the figure for the situation.

From the figure we see that a triangle ABC is formed.

We see that the Δ ABC is a right triangle.

Applying Pythagorean theorem for right triangle ABC to find the missing side.

AB^2=BC^2+AC^2

AB = 30 feet

BC = 12 feet

Plugging in values in the theorem.

30^2=12^2+AC^2

Solving for AC.

900=144+AC^2

Subtracting both sides by 144.

900-144=144+AC^2-144

756=AC^2

Taking square root both sides.

\sqrt{756}=\sqrt{AC^2}

27.5=AC

∴ AC=27.5 feet.

∴ Distance from the base of the escalator to the point on the first floor directly below the top of the escalator = 27.5 feet

Look for a pattern in the first three diamonds below. For the fourth diamond, explain how to find the missing numbers (?) if you
murzikaleks [220]

The general pattern that these diamonds follow is that the top number is the result of multiplying the numbers in the middle; while the bottom number results from adding these numbers. This pattern can be used to find the numbers in the fourth diamond. Moreover, the numbers that complete the diamonds are A (15,8), B (2,-3), C (4,2), D(4,8.5), E (-3.-4)

<h3>What is the general pattern in the diamonds?</h3>

Based on observation, you can determine in these diamonds the top number is obtained by multiplying the numbers in the middle, while the bottom number is obtained by adding these numbers.

<h3>What numbers complete the diamonds?</h3>

Diamond A

Top number: 15 (3x5)

Bottom number: 8 (3+5)

Diamond B

Top number: 2 (-2x-1)

Bottom number: -3(-2+-1)

Diamond C

4, 2 because 4x2 = 8 and 4+2 = 6

Diamond D

Top number: 4( 8x0.5)

Bottom number: 8.5(8+0.5)

Diamond E

-3,-4 because -3x-4= 12, and -3+-4= -7

5 + 6 - (-3) - 8 + 4 -3
Komok [63]
Okay, so -

We have one very important thing here. This little part <em>6 - (-3). </em>

Now, it's essential to remember that when we have two negatives like this, we simply draw a line straight down. It becomes a positive! 

So, our question is essentially <em>5 + 6 + 3 - 8 + 4 - 3 = ?</em> instead of <em>5 + 6 - (-3) - 8 + 4 - 3!</em> =)

With that in mind, we simply solve left to right. 

<em>11 + 3 - 8 + 4 - 3 = ?</em>

<em>14 - 8  + 4 - 3 = ?</em>

<em>6 + 4 - 3 = ?</em>

<em>10 - 3 = ?</em>

<em>7</em> is our final answer! =)

1)The pyramid has a square base that us inscribed in the circular base of the cone. Draw an image of the composite shape of the
DENIUS [597]

Answer:

Diameter of the circle is 8\sqrt{2} units

Step-by-step explanation:

It is given that the vertices of the square fall on the circle.

So, the diagonal of the square is the diameter of the circle.

Also, the diagonal and the two sides of the square form a right angled triangle.

By Pythogoras theorem,

hypotenuse^{2} =side^{2} +side^{2}

= 8^{2} +8^{2}

= 2(8^{2} )

hypotenuse=8\sqrt{2} units

Hence, the diameter of the circle is 8\sqrt{2} units
