Answer:
20x
Step-by-step explanation:
You would multiply 1/4 times 8. Or instead, you could divide 80 by 4. You would get 20 then you would multiply that by x and get 20x. Hope this helps.
The total area of the face of the watch to the nearest tenth of a square centimemter is 9.0 cm²
Since an electronics company is designing a watch with a face that is in the shape of a hexagon and two congruent trapezoids attached. The heights of the trapezoids and the apothem of the hexagon measure 2 centimeters each, and the length of the shorter base of each trapezoid is 1.5 centimeters, the radii of the hexagon, and the base of the trapezoid form a triangle of
- height, h = apothem of the hexagon = 2 cm and
- base, b = length of shorter base of trapezoid.
<h3>Area of the triangle</h3>
So, the area of this triangle is A = 1/2bh
= 1/2 × 1. 5 cm × 2 cm
= 1.5 cm × 1 cm
= 1.5 cm²
<h3>Area of the hexagon</h3>
Since there are 6 of such triangles in the hexagon, the area of the hexagon, A' = 6A
= 6 × 1.5 cm²
= 9.0 cm²
So, the total area of the face of the watch to the nearest tenth of a square centimemter is 9.0 cm²

Answer:
Is this the inter question
Answer:
It MAY be (7h-21). I COULD be wrong tho.
Step-by-step explanation:
Answer:
a. Scale Perimeter : 2.5 centimeters
Actual Perimeter : 13 centimeters
Actual Area : 10.5 square centimeters
b. Actual Perimeter : 130 mm
Actual Area : 1,050 mm
Step-by-step explanation:
a. 2.5 mm = 0.25 cm
2 (1 + 0.25) = 2.5
2 (3.5 + 3) = 13
3.5 x 3 = 10.5
b. 3.5 cm = 35 mm 3 cm = 30 mm
2 (35 + 30) = 130
35 x 30 = 1050
