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
Answer:
question 21 is x= 30
Step-by-step explanation:
when you multiply 7 by 5 you get 35 which is on the bottom side. So, to get x you multipy 6 and 5 and that equals 30.
You need to first set up the equation:
It would look like 90 divided by 360 multiplied by the given
circumference which is 72 cm.
So 90 / 360 x 72
Simply the fraction above, it will give us:
¼ x 72
So the answer would be 18 cm that is the length of DE (minor
arc)
You will get 20 tickets.<span />

<h2>Explanation:</h2>
Here we have the following inequality:

In order to graph the shaded region, we have to graph the equation of the line
whose slope is
and y-intercept
. So the graph of the line is shown in the First Figure below.
To find the shaded region we need to have a look at the symbol > that indicates that the shaded region is above the graph of the line and. Since this doesn't include the symbol =, then the line is dotted. Therefore, the resulting region is shown in the second Figure.
