A decimal is a number expressed in the scale of tens. Commonly speaking we talk about decimals when numbers include a decimal point to represent a whole number plus a fraction of a whole number

For example 10.00

Answer:

Decimals represent fractions. For e.g. In the following figure, One block divided into 10 equal parts. In fractional terms, each part is 1/10 (one-tenth) of a unit. It can be written as 0.1 in decimal notation.

Decimal numbers are numbers that

include tenths, hundredths,

thousandths or any other fraction

based on a power of ten. They're

written by putting the whole

numbers to the left of the decimal

point, and the fraction to the right.

In algebra, a decimal number can

be defined as a number whose

whole number part and the

fractional part is separated by a

decimal point. The dot in a

decimal number is called a

decimal point. The digits following

the decimal point show a value

smaller than one.

when there are non-zero digits on

both sides of the decimal point,

they should say, "and," where

they see the decimal point. For

example, 2.17 is read, "two and

seventeen hundredths." Use

models on a 10 x 10 grid as

necessary to guide the class in

comparing decimals numbers

using > and <.>

You should become efficient in

using the four basic operations

involving decimals—addition,

subtraction, multiplication, and

division.

If DA equals 6 units, AB equals 16 units, and HE equals 36 units, what does EF equal?​
yuradex [85]

Answer:

B. 96 units

Step-by-step explanation:

DA is 6 units and HE is 36 units. There are the same side, but HE is 6 times larger.

AB is 16 units, but since all the sides on the left shape are 6 times larger, EF has to be 16*6, which is 96 units.

Hope this helps

On a coordinate plane, 3 triangles are shown. Triangle B C D has points (1, 4), (1, 2), (5, 3). Triangle B prime C prime D prime
Tresset [83]

The rule which describe the composition of transformations that

maps ΔBCD to ΔB"C"D" is:

Reflection across the y-axis composition translation of 6 units x,

negative 5 units y ⇒ last answer

Step-by-step explanation:

Let us revise the reflection across the y-axis , horizontal translation

and vertical translation

1. If point (x , y) is reflected across the y-axis, then its image is (-x , y)

2. If point (x , y) is translated h units to the right, then its image is

   (x + h , y), if translated h units to the left, then its image is (x - h , y)

3. If point (x , y) is translated k units up, then its image is (x , y + k),

   if translated k units down, then its image is (x , y - k)

∵ The vertices of triangle BCD are (1 , 4) , (1 , 2) , (5 , 3)

∵ The vertices of triangle B'C'D' are (-1 , 4) , (-1 , 2) , (-5 , 3)

∵ The x-coordinates of the vertices of Δ B'C'D' have the same

   magnitude of x-coordinates of Δ BCD and opposite signs

∴ Δ B'C'D' is the image of Δ ABC after reflection across the y-axis

∵ The vertices of triangle B'C'D' are (-1 , 4) , (-1 , 2) , (-5 , 3)

∵ The vertices of triangle B''C''D'' are (5 , -1) , (5 , -3) , (1 , -2)

∵ The image of -1 is 5 and the image of -5 is 1

∴ The x-coordinates of the vertices of triangle B'C'D' are added by 6

∵ The image of 4 is -1 , image of 2 is -3 and the image of 3 is -2

∴ The y-coordinates of the vertices of triangle B'C'D' are subtracted

   by 5

∴ Δ B"C"D" is the image of Δ B'C'D' by translate 6 units to the right

  and 5 units down ⇒ (x + 6 , y - 5)

The rule which describe the composition of transformations that

maps ΔBCD to ΔB"C"D" is:

Reflection across the y-axis composition translation of 6 units x,

negative 5 units y
