The first one shows 1 cm and 7 mm, we need to convert 7 mm to cm
1 cm + 7 mm
= 1 cm + \frac{7}{10} cm
= 1 cm + 0.7 cm
= 1.7 cm
The first one is 1.7 cm

The second one shows 11 inches and 5/16 inches. Between number 11 and 12, there are 16 strips and the pointer lies on fifth strip, thus it show 5/16 inches. The second one is 11\frac{5}{16} inches.

The third one shows 13 cm and 8 mm. We need to convert mm into cm.
13 cm + 8 mm
= 13 cm + 0.8 cm
= 13.8 cm
The third one is 13.8 mm

A, B &amp; C lie on a straight line.
bazaltina [42]

Answer:

x = 136°

Step-by-step explanation:

We can use a theorem to help us.

<em>Theorem: </em>

<em>The measure of an exterior angle of a triangle is equal to the sum of the measures of the remote interior angles.</em>

For exterior angle x, the remote interior angles are z and <CBD.

From the theorem, we get this equation.

x = z + m<CBD

We know z = 52°.

We need to find m<CBD.

Angles CBD and y are a linear pair. They are supplementary, so the sum of their measures is 180°. We are given y = 96°.

m<CBD + y = 180°

m<CBD + 96° = 180°

m<CBD = 84°

x = z + m<CBD

x = 52° + 84°

x = 136°

Stolb23 [73]
The answer is 58,420. If it is asking per year, and it is given in months all you need to do is multiply by 12 . add 250*12 and 35*12 and 55,000 and you get 58,420.

Imagine that you are given two linear equations in slope-intercept form. You
murzikaleks [220]

The correct answer is option D.

<h3>What is Straight Line?</h3>

A straight line is an infinite length line that does not have any curves on it. A straight line can be formed between two points also but both the ends extend to infinity.

When two equations have same slope and their y-intercept is also the same, they are representing the line. In this case one equation is obtained by multiplying the other equation by some constant.

If we plot the graph of such equations they will be lie on each other as they are representing the same line. So each point on that line will satisfy both the given equations so we can say that such equations have infinite number of solutions.

Consider an example:

Equation 1: 2x + y = 4

Equation 2: 4x + 2y = 8

If you observe the two equation, you will see that second equation is obtained by multiplying first equation by 2. If we write them in slope intercept form, we'll have the same result for both as shown below:

Slope intercept form of Equation 1: y = -2x + 4

Slope intercept form of Equation 2: 2y = -4x + 8 , ⇒ y = -2x + 4

Both Equations have same slope and same y-intercept. Any point which satisfy Equation 1 will also satisfy Equation 2. So we can conclude that two linear equations with same slope and same y-intercept will have an infinite number of solutions.

Thus, the correct answer is option D.

Triangle RST has vertices R(−2, 2), S(1, 1), and T(−1, −3). Find the coordinates for the image of each vertex for the given rota
Vesnalui [34]

Answer:

A. R'(-2,-2),S'(-1,1), and T'(3,-1)

Step-by-step explanation:

Given:

Vertices of triangle RST are R(-2,2),S(1,1), and T(-1,-3).

Rotation is 90° about the center O(0,0). The rotation is counter-clockwise as the angle of rotation is positive.

Now, the co-ordinate rule for 90° rotation counter-clockwise is given as:(x,y) → (-y,x)

x and y values interchange their places with y becoming negative when interchanged.

So, R(-2,2) → R'(-2,-2)

S(1,1) → S'(-1,1)

T(-1,-3) → T'(-(-3),-1)

⇒T(-1,-3) → T'(3,-1)

Therefore, the image of the vertices are R'(-2,-2),S'(-1,1), and T'(3,-1).
