Axis

Step-by-step explanation:

A rotation is a circular movement of an object around a center (or point) of rotation. A three-dimensional object can always be rotated about an infinite number of imaginary lines called rotation axes . If the axis passes through the body's center of mass, the body is said to rotate upon itself, or spin. A rotation around an external point, e.g. the planet Earth around the Sun, is called a revolution or orbital revolution, typically when it is produced by gravity. The axis is called a pole.

The inequality that represents the second graph is:  [tex]x\leq3[/tex]

Step-by-step explanation:

From the second number line, you can see that the circle is closed on positive 3 and the arrow is pointing left - the direction of negative numbers, so you know that the value of x must be less than or equal to 3. Thus, you can write the inequality: [tex]x\leq3[/tex] - X is less than or equal to 3

The answer is $7

Step-by-step explanation:

The answer is $7 because $42 divided by 6 = 7.

Answer:

The price of one movie ticket without a coupon would be $9.

Step-by-step explanation:

one movie ticket: x

$42 = 6(x- 2)

$42 = 6x- $12

Move the 12 to the other side.

 42  = 6x  - 12

+ 12            +12

____________

 54  = 6x

Now divide 6 from both sides.

  [tex]\frac{54}{6}[/tex] = [tex]\frac{6x}{6}[/tex]

  9 = x

Answer:

The estimate part is D or the square root of 48 and the rectangle is 13.8 units long and 6.9 units wide. Have Fun on Savvas Bro

Step-by-step explanation:

The required answer is,

Width of the rectangle = 6.325 units

Length of the rectangle = 12.65 units

Side length of the square the 6.325 units.

A plane figure with four straight sides and four right angles, especially one with unequal adjacent sides, in contrast to a square.

Now it is given that,

The length of a rectangle is twice the width. The area of the rectangle is 96 square units.

The area of the rectangle = Length × Width

Length = 2W

96 square units = 2W × W

96 = 2W²

W² = 96/2

W² = 48

W = √48

Width of the rectangle = 6.928203 units

Approximately = 6.928 units

Now,

Length = 2 × Width

            = 2 × 6.928

            = 13.86 units

• Now,we need to divide the rectangle into two squares with equal area, and estimate the side length of each​ square,

When we divide a rectangle into 2 squares,

The length is divided into two.

Hence, the length of the rectangle = 13.86 units

13.86 units ÷ 2 = 6.928 units.

Hence, the side length of the square the 6.928 units.

Step-by-step explanation:

1) [tex]\frac{3}{2} \\[/tex] = 1.5 because the numerator goes int the denominator 1 time and then you ahve left over [tex]\frac{1}{2}[/tex] which is .5 .

2) [tex]\frac{5}{2}[/tex] = 2.5 because the 5 goes into the denominator 2 times and then you have left over .5 .

3) [tex]\frac{1}{4}[/tex] = .25 because a 1 is divided by 4.

Answer:

48  cans of pineapple juice he should use.

Step-by-step explanation:

This, is a problem of ratio where we have to use the concept

a:b = c:d which can be also written as

a/b = c/d

______________________________________________________

According recipe

we find ratio of pineapple and orange juice

amount pine apple juice :  amount of orange juice = 2 cans : 3 cans

Thus, ratio of pineapple and orange juice = 2:3

___________________________________

Given that this recipe is used for making juice in large batch for a community function

Given

amount of orange juice = 72 cans

let the amount of  pine apple juice be x

ratio of pineapple and orange juice in this case

amount pine apple juice :  amount of orange juice = x cans : 72 cans

ratio of pineapple and orange juice in this case= x : 72

since recipe used is same.

ratio will be same in both case that in recipe ratio and large batch preparation for community function

Thus,

x:72 = 2:3

which can also be written as

x/ 72 = 2/3

x = 2/3 * 72 = 48

Thus, 48  cans of pineapple juice he should use.

Answer:

x^4*y^2

Step-by-step explanation:

Whenever you multiply a number by itself, add one to its power. X is actually x^1, but we don't write that. Keep on adding 1 to the power for every x you multiply together and do the same thing for y. You will get x^4*y^2 as the answer.

Answer:

x^4y^2

Step-by-step explanation:

because you have 4 x so you put x^4 and you have 2 y so you do y^2 which the answer is x^4y^2

From the diagram, we have that the segment [tex]\overline {AB}[/tex] is given as the measured distance between the points A and B while the measured segment [tex]\overline {CD}[/tex] is constructed on the line m, starting from a point C and using a compass whose width is adjusted to the length of the segment [tex]\overline {AB}[/tex] and with the metal tip of the compass placed at C, to draw an arc the crossed the line m at a point which is then marked and labelled as then point D

Therefore the length of the segment [tex]\overline {AB}[/tex] is equal to the length of the segment [tex]\overline {CD}[/tex] and the relation is expressed as [tex]\overline{AB} \cong \overline{CD}[/tex].

15.25 is the answer of the question

The value of x is x = int(13.25 + 4/2) is 15

Integers are negative or positive whole numbers. Given the expression for x,  x=int(13.25 + 4/2)

This means that we are to express  the result of x as an integer

Solving the expression 13.25 + 4/2

[tex]=13.25+\frac{4}{2} \\=13.25 + 2\\=15.25\\[/tex]

In order to convert this result into an integer, we will approximate it to the nearest whole number. Hence:

[tex]x=int(15.25)\\x \approx 15[/tex]

This shows that the value of x is x = int(13.25 + 4/2) is 15

Answer:

the answer is b 9 · x + 9 · 3 + 15x

The expression 9(x + 3) + 15x is equivalent to the given expression.

Given,

9(x + 3) + 15x = 9 · x + 9 · 3 + 15x

9(x + 3 + 15)x = 9 · x + 9 · 3 + 9 · 15x 9 · x + 3 + 15x

We need to find which expression is equivalent to the given expression after using the distributive property.

We have the distributive property of multiplication over addition and subtraction.

Example:

- distributive property of multiplication over addition

= a x ( b + c )

= a x b + a x c

- distributive property of multiplication over addition and subtraction.

= a x ( b - c )

= a x b - a x c

Find the expression using the distributive property.

We have,

- 9(x + 3) + 15x

= 9 · x + 9 · 3 + 15x

This is equivalent to 9 · x + 9 · 3 + 15x

- 9(x + 3 + 15)x

= ( 9 · x + 9 · 3 + 9 · 15 ) x
= 9 . x . x + 9 . 3 . x + 9 . 15 . x

This is not equivalent to 9 · x + 9 · 3 + 9 · 15x 9 · x + 3 + 15x

Thus the expression 9(x + 3) + 15x is equivalent to the given expression.

Answer:

n = m - a

Step-by-step explanation:

Given:

a = m − n

Where,

Actual cost of the item = a

Original price of the item = m

Amount of Coupon = n

Solve the formula for the amount of the coupon

Making n the subject

a = m − n

Subtract m from both sides

a - m = m - n - m

a - m = - n

Divide both sides by -1

(a - m) / -1 = -n / -1

- a + m = n

Can also be written as

n = m - a
