Answer:

√18

Step-by-step explanation:

Ok, there's 5 squares that make up the box since the top's missing, so do:

90/5 --> 18

Since squares are simply length^2 to get the area, square root this value to give you your answer for each side length of this box:

√18

WHAT IS THE HCF OF 21 28 42

gulaghasi [49]

Answer:

Step-by-step explanation:

21 = 3 * 7

28 = 2 * 2 * 7

42 = 2 * 3 * 7

Collecting common factors:

t is common to all 3 sets of factors so

HCF = 7.

A father is 60 years old just son is half his age how old was the boy when his father was four times his age

gayaneshka [121]

So, what you would have to do is figure out how old he is not which is 30 yrs old because it is half of 60.

So, after this you would have to find a number that would go into 60 four times which is 15.

So, your answer would be 15.

application. Line segment AB is a translation of line segment CD 6 units down. Drag line segment CD and try to move it onto line

Svetllana [295]

Solid transformation is a method that requires a change in the length of sides of a given shape or a change in its orientation. Thus the required answers are:

i. Yes, line segment AB is the same as line segment CD.

ii. This implies that translation does not affect the length of a given line, but there is a change in its location.

Solid transformation is a method that requires a change in the length of sides of a given shape or a change in its orientation. Some types of transformation are reflection, translation, dilation, and rotation.

Dilation is a method that requires either increasing or decreasing the size of a given shape.
Translation is a process that involves moving every point on the shape in the same direction, and the same unit.
Reflection is a method that requires flipping a given shape over a given reference point or line.
Rotation requires turning a given shape at an angle about a given reference point.

Thus in the given question, translation would not affect the length of line segment AB, thus line segment AB and CD are the same. Also, A translated line segment would have the same length as its object, but at another location.
