Answer:
- small prism: 630 m²
- large prism: 2520 m²
Step-by-step explanation:
The total surface area of the prism is the sum of the base area and the lateral area. The base area is made up of two right triangles, so will be the product of the triangle leg dimensions. The lateral area is made up of three rectangles whose width is that of the prism and whose equivalent length is the perimeter of the triangle base.
For the smaller prism, the area is ...
(20 m)(21 m) +(3 m)(20 m + 21 m + 29 m) = 420 m² +210 m² = 630 m²
The larger prism is similar, with a scale factor of 2, so its area will be 2² = 4 times that of the smaller prism:
4×630 m² = 2520 m²
__
In summary, the total surface area of each prism is ...
- small prism: 630 m²
- large prism: 2520 m²
Answer:
6.9
Step-by-step explanation:
sinX=opposite/hypotenuse
sin35=a/12
a=12*0.57357643635
a=6.88291723621≈6.9
Answer:
Only option C is correct, i.e. The input, or independent variable, is years in operation.
Step-by-step explanation:
Given is the scatter plot of Years in Operation vs. Enrollment at Daycare Center.
The input is always independent variable and is plotted along x-axis.
The output is always dependent variable and is plotted along y-axis.
From the graph, it is clearly visible that:-
x-axis: Years in Operation.
y-axis: Enrollment at Daycare Center.
It means <u>"The input, or independent variable, is years in operation."</u>
Hence, only option C is correct, i.e. The input, or independent variable, is years in operation.
Answer: p = 1/8
Step-by-step explanation:
If p = 1/8, then 7 would equal 7/8 and 2n would become 2n/8 or 1/4n
Answer:
19,27 cm^2
Step-by-step explanation:
area of triangle = (6 x 3)/ 2 = 9 cm^2
circle area : 3^2 x 3,14 = 28,27 cm^2
area of shaped region = 28,27 - 9 = 19,27 cm^2
