Answer:
#1
<u>Area of triangle backdrop:</u>
- A = 1/2bh = 1/2(10.5)(8.5) = 44.63 m²
<u>Area of the cloth:</u>
<u>Uncovered area:</u>
Choice A
#2
<u>Area of the cut piece:</u>
- A = πr² = 3.14*7.6² = 181.37 cm²
<u>Area of the square piece:</u>
<u>Remaining piece is:</u>
- 1156 - 181.37 = 974.63 cm²
Choice B
Answer:
If the rational number is ab then, te reciprocal is ba
Step-by-step explanation:
Suppose that rational number is ab
Then, the reciprocal of that number is ba
Answer:
x = 7
Step-by-step explanation:
Because this is a right triangle, one angle is a right angle (90°). All triangles have all three angle measures adding up to 180°, so the other two angles' measures add up to 90° (90 + 90 = 180).
Combine like terms of the angle measures.
6x + 9x = 15x
-3 + (-12) = -15
15x - 15
Because the sum of the measures of the two angles have to equal 90,
15x - 15 = 90
Add 15 from both sides.
15x = 105
Divide both sides by 15.
x = 7
To check, substitute 7 in both expressions.
6(7) - 3 = 39
9(7) - 12 = 51
39 + 51 + 90 (the measure of the right angle) = 180, so the value of x is 7.
