Q18
360 = 0.2 a
a = 360 / .2 = 5(360)= 1800 audience members
Q19
Assuming the information is consistent we ignore the trapezoid; we have two triangles base 1.1 height 3.8 so the area for the pair is 2 (1/2) (1.1) (3.8) = 4.18 sq inches.
Q20
6(5)^2 - 5(4) + 8 = 6(25) -20 + 8 = 150 - 20 + 8 = 138
Q21
This is an LCM or least common multiple problem
LCM(12,8) = LCM(3(4),2(4))=3(2)(4)=24 weeks
Answer:
the answer to this is C. 129 cm
Answer:
The new coordinate of image of point B (-4, 6) will be B'(-2, 3) when a rectangle ABCD is dilated by a scale factor of One-half with a center of dilation at the origin.
Step-by-step explanation:
Considering the vertices of the rectangle ABCD
When a rectangle ABCD is dilated by a scale factor of One-half with a center of dilation at the origin, then the coordinate of image of point B can be calculated by multiplying the x and y coordinates of point B with 1/2.
i.e.
B(-4, 6) → B'(-4/2, 6/2) = B'(-2, 3)
Therefore, the new coordinate of image of point B (-4, 6) will be B'(-2, 3) when a rectangle ABCD is dilated by a scale factor of One-half with a center of dilation at the origin.
