The square root of 64 is 8, or -8

This is because 8 times 8 is 64

And -8 times -8 is 64 (because a negative times a negative is a positive)

The square root of 64 has both a negative and positive value because as we know it's 8 and -8. To square, you simply multiply the number by its self twice, since a negative number time a negative number is a positive number and a positive number times a positive number is also positive so -8x-8=64 and 8x8=64.

Hope this helped!

Use the information in the diagram to determine the height of the tree to the nearest foot.

Answer:

The correct option is A. The height of tree is 60 ft.

Step-by-step explanation:

From the given figure it is noticed that the building is creating a right angle triangle from a point and the tree divides the hypotenuse and base in two equal part.

According to midpoint theorem of triangle: In a triangle, if a line segment connecting the midpoints of two sides, then the line is parallel to third side. The length of line segment is half of the length of third side.

Using midpoint theorem of triangle, we can say that the length of tree is half of the building.

$Tree=\frac{1}{2}\times Building$

$Tree=\frac{1}{2}\times 120$

$Tree=60$

Therefore correct option is A. The height of tree is 60 ft.

What is X? x divided by 4/9 = 9/10

Damm [24]

Answer:

2/5

Step-by-step explanation:

$\frac{x}{\frac{4}{9} } =\frac{9}{10}$

$(\frac{9}{10})(\frac{4}{9} )=\frac{36}{90}$

36 divided by 90 is 2/5.

When solving for X you do the opposite to a number if you are moving it to the other side of the problem. so, since x is being divided by 4/9, 4/9 would be multiplied to the opposite or to the 9/10.
