Use the information in the diagram to determine the height of the tree. The diagram is not a scale

dusya [7]

In the given diagram, we can note that the tree divides the hypotenuse of the triangle as well as the side where the tree is based into halves.

In a triangle, when a line is drawn joining between the midpoints of two sides, this line is always parallel to the third side and equals half its length.

Applying this concept to the given diagram here, we will find that the tree is joining the midpoints of two sides of the triangle. this means that the tree is parallel to the building and the height of the tree is half the height of the building.

Therefore:
height of tree = 0.5 * 120 = 60 ft

A land surveyor places two stakes 500 ft apart and creates a perpendicular to the line that connects these two stakes. He needs

aksik [14]

Answer:

A perpendicular bisector is a perpendicular line that divides a line into two equal halves

step by step:

To apply the Perpendicular Bisector Theorem, the land surveyor will need to identify; the midpoint along the line connecting the two stakes

The reason why the surveyor needs to identify the midpoint is as follows:

According to the Perpendicular Bisector Theorem, all points on the perpendicular bisector of a line are of equal distance from the line's endpoint

In order to apply the perpendicular bisector, the surveyor would need to identify the midpoint from which the third stake can be placed 100 ft. along a perpendicular bisector drawn from the midpoint

Therefore, the surveyor needs to identify; the midpoint along the line connecting the two stakes

An aquarium tank holds 143 gallons of water. How much is this in liters? Use the following conversion: 1 gallon is 3.8 liters

uranmaximum [27]

Answer:

543.4 liters

Step-by-step explanation:

The conversion 1 gallon is 3.8 liters can be used as the rate.

To convert gallons into liters, multiply the numbers of gallons by the rate, 3.8.

143 gallons X 3.8 = 543.4 liters

Therefore 143 gallons is 543.4 liters.

*math* explantion needed!

Paha777 [63]

Answer:

two real, equal roots

Step-by-step explanation:

Start by finding the discriminant, b^2 - 4ac. The coefficients of this quadratic are a = 49, b = 42 and c = 9. The discriminant is therefore

(42)^2 - 4(49)(9) = 0. Rule: If the discriminant is zero (0), then the quadratic has two real, equal roots.

Alexio has 100 cards numbered 1-100, inclusive, and places them in a box. alexio then chooses a card from the box at random. wha

tatiyna

We are given

Alexio has 100 cards numbered 1-100, inclusive, and places them in a box

so, total number of outcomes =100

now, we have chooses a card from the box at random

that is multiple of 2 , 3 or 5

so, firstly, we will find number of possible outcomes that is multiple of 2 , 3 or 5

Firstly, we will find which can't be multiple of 2, 3 and 5

that will be

={ 1, 7,11,13,17,19 , 23 , 29 , 31 , 37 , 41, 43 , 47 , 49 , 53, 59 , 61 , 67, 71, 77, 79, 83, 89 , 91 , 97 }

so,

number of possible outcomes =100-25=75

now, we can find probability

probability = (number of possible outcomes )/(total number of outcomes)

now, we can plug values

and we get

$p=\frac{75}{100}$

$p=\frac{3}{4}$ .................Answer
