Answer:
2 > 1
Step-by-step explanation:
-6 < -3 to -6/-3 > -3/-3 to 2 > 1
When dividing or multiplying by a negative, flip the inequality sign.

Answer:
Step-by-step explanation:
From the figure attached,
Point B has been dilated to form point B'.
B(3, 1) → B'(6, 2)
→ B'[(2 × 3), (2 × 1)]
Since rule for the dilation of a point (x, y) by a factor of k is,
B(x, y) → B'(kx, ky)
By comparing the coordinates k = 2 is the scale factor by which the point B has been dilated about the origin.
Therefore, other vertices of the quadrilateral will be,
A(-2, 3) → A'(-4, 6)
C(1, -1) → C'(2, -2)
D(-3, -2) → D'(-6, -4)
Answer:
Step-by-step explanation:
4 cups of J for every 7 cups of soda 4:7
21 cups of soda will take 12 cups of J
If you take the 7 and multiply by 3 you get the 21.
So you will need to multiply the 4 by the 3 to get the 12. You need to keep everything in proportion.
4:7 same as 12:21
Answer:
the radius of the circle is 6cm
Step-by-step explanation:
the area of a circle is given to be = 36πcm²
radius of the circle = ?
to find the radius of the circle lets start by applying the formula for finding the area of a circle.
area of a circle = πr²
36πcm² = πr²
36π = πr²
divide both sides by π
36π/π = πr²/π
36 = r²
to get the value of r we are going to look for a way of getting rid of the square on "r" by squaring 36
r² = 36
r =√36
r = 6cm
therefore the radius of the circle is 6cm
