Answer:
1d 6.742 1e 6
Step-by-step explanation: By sketching out the graph you can see the positive x intercept to find 1d
You can also replace h with 25 and isolate t to find 1e
The area shaded in green is 864 cm²
<h3>Similar figures</h3>
Similar figures, corresponding angles are congruent and the sides are ratio of each other. Therefore,
AB / PQ = CD / RS
30 / 10 = 24 / RS
30RS = 240
RS = 240 / 30
RS = 8 cm
let find the height of trapezium PQRS.
AB / PQ = 36 / h
30 / 10 = 36 / h
30h = 360
h = 360 / 30
h = 12 cm
Therefore,
area of the green portion = area of ABCD - area of PQRS
<h3>Area of a trapezium</h3>
Therefore,
area of ABCD = 1 / 2(24 + 30)36 = 1 / 2 (54)36 = 1944 / 2 = 972 cm²
area of PQRS = 1 / 2(10 + 8)12 = 1 / 2(18)12 = 216 / 2 = 108 cm²
Area of the green portion = 972 - 108 = 864 cm²

Answer:
1/4
Step-by-step explanation:
Since there is 4 colors and four rooms there is a 1/4 possibility that she paints the room green.
Answer:
1/2
Step-by-step explanation:
1/2 x 1/2 = 1/4
3/4 x 1/2 = 3/8
1/1 x 1/2 = 1/2
5/4 x 1/2 = 5/8
(5/4 = 1 1/4)
