Answer:
3. 294 m²
4. 185,856 mm²
Step-by-step explanation:
To find the surface area of any figure, you can simply find the sum of the areas of all the sides. In question 3, the figure is a triangular prism that has two triangular bases and three rectangular sides. The measurements for the triangles are b = 9m and h = 6m. The formula for the area of a triangle is base times height divided by 2, or 9 x 6 = 54/2 = 27 m². However, since there are two triangular bases, the area for both is 54 m². The measurements for the other three rectangles are given:
7(10) + 8(10) + 9(10) = 240 m² + 54 m² = 294 m²
The surface area of a cube is much easier since all sides are equal and can be found using the formula:
SA = 6s², where 's' represents the measure of a side.
SA = 6(176)² = 185,856 mm²
The two numbers are 0.85 and 0.15
if you add them together you get 1, 0.85+0.15=1
and if you subtract them you get 0.7, 0.85-0.15=0.7
Answer:
Edible fruit amount is 4.8 ounce to 5.6 ounce
Step-by-step explanation:
Given as
The seed and skin of avocados is about 30%-40%
And the weight of avocados is 8 ounce
So, the weight of seed and skin is about 30% of 8 to 40% of 8
i.e 2.4 ounce to 3.2 ounce
Then the edible fruit is about 60% to 70%
i.e 60% of 8 to 70% of 8
Thus edible fruit of avocados = 4.8 ounce to 5.6 ounce Answer
Since you have the length and the area, you can assume the width
1496/44 = Width Because Area = L * W
Width = 34
So this is a ratio problem
44/11 = ratio
So, the ratio is 4:1
So since we have the width, we can divide the width of the school banner by 4 because of the scale
34/4 = 8.5 = width of the sign
The area of the sign is 8.5*11 = 93.5
and the perimeter is just that,
8.5 * 2 + 11*2 = 39
Perimeter = 39 inches
Area = 93.5 inches²
