Answer:
15-5(4k-7)=50
<=> 15 - 20k + 35 = 50
<=> 50 - 20k = 50
<=> -20k = 0
<=> k=0

Answer:
Option 1: triangle HFG is congruent to triangle KIJ
Step-by-step explanation:
F and I are same as they are on 90 degrees.
In figure 1, from I to K is the height of the triangle.
In figure 2, from F to H is the height of the triangle.
Therefore, IK is congruent to FH
In figure 1, I to J is the base of the triangle from 90 degrees.
In figure 2, F to G is the base of the triangle from 90 degrees.
Therefore, IJ is congruent to FG
Therefore, triangle HFG is congruent to triangle KIJ.
The first option is correct.

So the anser would be (3×6)+(3×6)=36 because 3×6 is 18 and if you multiply 18×2=36 so (3×6)+(3×6)=36
Answer:
The hat weight = 81.166 g
Step-by-step explanation:
∵The figure formed by a rectangle and two identical semi-circle
∵ The length of the rectangle = 52 cm = 0.52 m
∴ The length of the two diameter = 52 cm = 0.52 m
∴ The radius of the semi-circle = 52 ÷ 4 = 13 cm = 0.13 m
∴ The width of the rectangle = 36 - 13 = 23 cm = 0.23 m
∴ The area of the rectangle = 0.52 × 0.23 = 0.1196 m²
∴ The area of the semi-circles = π (0.13)² = 0.0531 m²
∴ The area of the hat = 0.1196 + 0.0531 = 0.17269292 m²
∵ 1 m² = 470 g
∴ The weight of the hat = 0.17269292 × 470 = 81.16567 ≅ 81.166 g
