Reflection all symmetry is the quality a design has if it maintains all characteristics when it is (blank) lying in its plane. A) rotated about an axis
B) translated along a line
C) rotated about a point

Reflectional symmetry is the quality a design has if it maintains all characteristics when it is (blank) lying in its plane Option: A) rotated about an axis.

What is reflectional symmetry?

Consider a plane. Consider a design or shape on that plane. Now consider an axis.

If we think of that axis as a mirror, and on the opposite side of that axis create the image of the considered shape, then if the shape's image looks exactly as the shape itself, then that shape is called to have a reflectional symmetry.

Instead of that mirror intuition, we can also think that we sort of rotated that image about that considered axis, and after half rotation, the figure is again onto its plane. If that rotated figure looks alike to the initial figure, then that figure has rotational symmetry.

Thus, reflectional symmetry is the quality a design has if it maintains all characteristics when it is (blank) lying in its plane Option: A) rotated about an axis.

Are the fractions 1.3 over 5.2 equal to 12 over 48

Answers

the answer is yes.
you can find each fraction and see if they are equal or not so in this question you can say:
1.3/5.2 = 0.25 and 12/48 = 0.25 so both of them are equals to 0.25 :)))
I hope this is helpful
have a nice day

$(1.3)/(5.2)= (1.3*10)/(5.2*10)=(13)/(52)=(13\cdo:13)/(52:13)=(1)/(4)=(1*12)/(4*12)=(12)/(48)$

So, yes. The fractions are equal.

Write an expression using the distributive property that can be used to find the quotient 56÷4.

Answers

The quotient of 56 ÷ 4 is 14

Further explanation

Order of Operations in Mathematics follow this following rule :

Parentheses
Exponents
Multiplication and Division
Addition and Subtraction

This rule is known as the PEMDAS method.

In working on a mathematical problem, we first calculate operation that is in parentheses, follow by exponentiation, then multiplication or division, and finally addition or subtraction.

Let us tackle the problem!

This problem is about DIstributive Property.

$( a + b ) * c = ( a * c ) + ( b * c )$

$( a + b ) / c = ( a / c ) + ( b / c )$

Given :

56 ÷ 4 = ?

$56 / 4 = ( 40 + 16 ) / 4$

$56 / 4 = ( 40 / 4 ) + ( 16 / 4 )$

$56 / 4 = ( 10 ) + ( 4 )$

$56 / 4 = \boxed {14}$

Final answer:

The distributive property can be used to simplify the quotient 56÷4 by breaking 56 into 28+28 and then dividing each by four. The resultant expression is 28÷4 + 28÷4 which equals 14.

Explanation:

The question asks for an expression that can be used to find the quotient 56÷4 using the distributive property. This property in mathematics allows you to break down a complex calculations into simpler ones. In this case, we can break 56 into 28+28 and then divide each by 4. So, the expression using the distributive property would be 28÷4 + 28÷4. When you solve this, it simplifies to 7 + 7 which gives the correct quotient of 14, same as 56÷4.

6b - 49 =2(b - 3)

Answers

You always start by simplifying.
6b-49=2(b-3) becomes 6b-49=2b-6
From there you can group the b's together by subtracting 2b from both sides, leaving you with 4b-49=-6
Now you can get the b's alone by adding 49 (to cancel out -49) to both sides, giving you 4b=43, You're still trying to get b by itself, so what you'll do is divide both sides by 4, giving you b=10.75

$6b - 49 =2(b - 3)\n 6b-49=2b-6\n 4b=43\n b=(43)/(4)$
