What is 9 times 3/4?

Answers

Answer 1

Answer: When multiplying a whole number by a fraction, put the whole number as a fraction over one. 9/1 times 3/4. When multiplying fractions, you multiply straight across. 9(3)=27 and 1(4)=4. The new fraction is 27/4.

What is true concerning the lines graphed by the system of equations shown below 8x+6=2y 12x-3=3y

Answers

Answer: the lines are parallel to each other

Step-by-step explanation:

First, what we can do is solve both equations for y, putting them in slope-intercept form, y = mx + b:

2y = 8x + 6 3y = 12x - 3
/ 2 / 2 / 3 / 3
y = 8x/2 + 6/2 y = 12x/3 - 3/3
y = 4x + 3 y = 4x - 1

For both equations, m = 4, or they have the same slope of 4. Lines that have the same slope are parallel to each other.

ABCD is a rectangle. Find the length of each diagonal.ac=2(5a+1) bd=2(a+1).

Answers

The length of the diagonal of the rectangle is d = 2

What is the diagonal of a rectangle?

The diagonal of a rectangle is calculated by the formula

From the Pythagoras Theorem , The hypotenuse² = base² + height² , and

Diagonal of a Rectangle = √ ( Length )² + ( Width )²

Given data ,

Let the rectangle be represented as ABCD

Now , the diagonal of the rectangle is AC and BD

The measure of AC = 2 ( 5a + 1 )

And , the measure of BD = 2 ( a + 1 )

For a diagonal of a rectangle ,

The two diagonals of the rectangle will be same

So , the measure of AC = measure of BD

Substituting the values in the equation , we get

2 ( 5a + 1 ) = 2 ( a + 1 )

On simplifying the equation , we get

Divide by 2 on both sides of the equation , we get

5a + 1 = a + 1

Subtracting a on both sides of the equation , we get

4a + 1 = 1

Subtracting 1 on both sides of the equation , we get

4a = 0

a = 0

Now , substitute the value of a in measure of AC , we get

The measure of diagonal AC = 2 ( 5 ( 0 ) + 1 )

The measure of diagonal AC = 2

Hence , the measure of diagonals of the rectangle = 2

Rectangle diagonals are equal.

2(5a+1) = 2(a+1)
10a + 2 = 2a + 2
10a -2a = 2 - 2
8a = 0
⇒ a = 0

AC = 2(5a+1) = 2(5 × 0 +1)= 2(0 + 1) = 2 × 1 = 2
BD = 2(a+1) = 2(0 + 1) = 2 × 1 = 2

Ansver: AC = BD = 2

The value of the 2in 204.75 is how many times the value of the 2 in 103.52

Answers

Answer:

10000

Step-by-step explanation:

Given : Number :204.75

Number :103.52

To Find:The value of the 2 in 204.75 is how many times the value of the 2 in 103.52?

Solution:

Number :204.75

Value of 2 is 200

Number :103.52

Value of 2 = $(2)/(100)=0.02$

So, $10000 * 0.02 = 200$

Thus 10000 times of 0.02 is 200.

So, the value of the 2 in 204.75 is 10000 times the value of the 2 in 103.52.

I made it into an equation and took out all the other numbers so the equation would be 000.02x=200 and your trying to find x so you divide 200 by 000.02 equals 10000 and if you put it back in the equation 000.02(10000)=200 it comes out 200 so the answer is 10000

Quadrilateral ABCD is located at A(−2, 2), B(−2, 4), C(2, 4), and D(2, 2). The quadrilateral is then transformed using the rule (x − 2, y + 8) to form the image A'B'C'D'. What are the new coordinates of A', B', C', and D'? Describe what characteristics you would find if the corresponding vertices were connected with line segments.

Answers

The new coordinates are A(-4, 10), B (-4, 12), C (0, 12) and D (0, 10). If you were to connect these, it would take the shape of a rectangle.
