Answers

Answer:

a. A capital letter that have corresponding angles is the letter 'E'

b. A capital letter that have alternate angles is the letter 'N'

Step-by-step explanation:

The capital letter 'F' is made two horizontal parallel lines that touch a common transversal. Therefore, in the letter F, the two horizontal parallel lines form corresponding angles with the transversal below each parallel line

Similarly, the letter Z form alternate angles below the horizontal parallel lines and the inclined diagonal

a. Another capital letter that have corresponding angles is the letter 'E'

b. Another capital letter that have alternate angles is the letter 'N'

Answers

Answer:

J

Step-by-step explanation:

1. y = mx + c ( equation of a straight line,where "c" is the y intercept, i.e, the y co-oridnate of where it cuts the y-axis)

2. It is now clear to see that the value of "c", the y co-ordinate of the point of intercept is 3, eliminating F and G as options

3. Substitute a given point into the equation y = mx + 3 to solve for "m", the gradient. I chose (3; 1) as it is the only visible point that lies on the straight line

4. Solve for "m" algebraically and you'll find that the gradient is -2/3

5. Substitute "m" back into the equation and you'll find that your equation is y = -2/3x + 3 or J

ALTERNATIVELY:

You could just find the value of "c" as stipulated above, which would leave you with H and J as options. But since you know the coefficient of x in the equation is the gradient, you can just tell by looking at the line whether or not it will have a positive or negative gradient. The gradient is negative since the line is sloping downwards, so you're only option is J.

A rectangle with an area of 61 units” is dilated by a scale factor of ;. Find the area of
the rectangle after dilation. Round your answer to the nearest lenth, if necessary.

Answers

Answer:

34 units

Step-by-step explanation:

I decided that one side is 61 units and the other is 1 unit, since that would make the area 61 units.

Then I multiplied 61 by 3/4, which equals a new length of 45.75 units, and I also multiplied 1 by 3/4, which equals a new length of 0.75 units.

Finally, I solve for the area of the rectangle:

45.75 x 0.75 ≈ 34 units (rounded to the nearest whole number)
