5025.41

Step-by-step explanation:

$50.50 and 16 cents - $40.50 and 9 cents = $40.00 and 10 cents per mile. For x miles, we multiply $40.00 and 10 cents by x miles.

Also, we could convert dollars to cents by multiply it by 100 Since $1 =100 cents.

5066 - 40.59 cents = 5025.41 cents. For x miles, 5025.41 cents.

convert 0.25 with the 5 recurring to a fraction in its simplest form.

Step-by-step explanation:

I'm taking this to mean

x = 0.255555555555... If this is not correct, leave a note. Multiply by 100

100 x = 25.55555555555555 ...     Divide by 10

  10x =    2.55555555555555 ...     Subtract

90 x = 23

x = 23/90    

Try putting 23/90 in your calculator. You will find it is 0.25555555... just what you were given

Step-by-step explanation:

2. Given the information above, we can say that x + 60 = 127.

[tex]x + 60 = 127[/tex] [tex]x + 60 - 60 = 127 - 60[/tex] (Subtract 60 from both sides)[tex]x = 67[/tex]

A. The measure of ∠′ after a reflection across the line y = x


B. The coordinates of A' after rotations of 360°


C. The coordinates of B' after a translation of 3 units left and 2 units up


D. The perimeter of square A'B'C'D'

Answers

Answer:c

Step-by-step explanation:

Transformation involves changing the position of a shape in a coordinate plane.

The corresponding parts that will not remain the same is (c) the coordinates of B' after a translation of 3 units left and 2 units up

Reflection is a rigid transformation;

This means that, options (a) and (d) will remain unchanged for the image and the pre-image of square ABCD

Rotating a shape 360 degrees will return the shape to its original position.

This means that: (b) will remain unchanged

The coordinates of B' after translation will not remain the same, because the points will move to (x + 3, y + 2).

Hence, option (c) is true

which binary value is equal to the decimal number 210?

Answers

210 is 11010010 in binary form

Answer is 11010010.

What are the Rules to Convert Decimal to Binary?

Write down the number.

Divide it by 2 and note the remainder.

Divide the quotient obtained by 2 and note the remainder.

Repeat the same process till we get 0 as the quotient.

Write the values of all the remainders starting from the bottom to the top.

Step by step solution:

Step 1: Divide (210)  successively by 2 until the quotient is 0:

210/2 = 105, remainder is 0

105/2 = 52, remainder is 1

52/2 = 26, remainder is 0

26/2 = 13, remainder is 0

13/2 = 6, remainder is 1

6/2 = 3, remainder is 0

3/2 = 1, remainder is 1

1/2 = 0, remainder is 1

Step 2: Read from the bottom (MSB) to top (LSB) as 11010010.

So, 11010010 is the binary equivalent of decimal number 210 (Answer).

Given that x = 2.2 correct to 1 decimal place, find the interval that

contains the value of 4x + 3. Give your answer as an inequality.

Answers

Answer:

11.8

Step-by-step explanation:

The solution is 11.0 < 4x + 3 < 12.0

The inequality equation is 11.0 < 4x + 3 < 12.0 , where the value of the equation 4x + 3 = 11.8 , when x = 2.2

What is an Inequality Equation?

Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.

In an inequality, the two expressions are not necessarily equal which is indicated by the symbols: >, <, ≤ or ≥.

Given data ,

Let the inequality equation be represented as A

Now , the equation is P = 4x + 3

The value of x = 2.2

Correcting the value of x to one decimal place , we get x = 2.2

Substitute the value of x in the equation , we get

P = 4x + 3

when x = 2.2

P = 4 ( 2.2 ) + 3

P = 8.8 + 3

P = 11.8

Now , the inequality equation is 11.0 < 11.8 < 12.0

Hence , the inequality equation is 11.0 < 4x + 3 < 12.0 , where 4x + 3 = 11.8
