Answer:
248.95 square centimetres
Step-by-step explanation:
The surface area of a 3D figure is the sum of the areas of the exterior surfaces.
Here, we have one equilateral triangle as the base with base 13 and height 11.3. We also have three other congruent lateral triangles with base 13 and height 9.
The area of a triangle is denoted by A = (1/2) * bh, where b is the base and h is the height.
The area of the base triangle is:
A = (1/2) * bh
A = (1/2) * 13 * 11.3 = 73.45 cm²
The area of one lateral triangle is:
A = (1/2) * bh
A = (1/2) * 13 * 9 = 58.5 cm²
Since there are 3 such triangles, multiply 58.5 by 3:
58.5 * 3 = 175.5 cm²
Finally, add 175.5 to 73.45:
175.5 + 73.45 = 248.95 cm²
The answer is thus 248.95 square centimetres.

Answer:
I walk at a rate of 4 miles per hour, while the car travels at 10 miles per hour.
Step-by-step explanation:
Since I can walk 14 miles in the same time that it takes to travel 35 miles by car, if the car's rate is 6 miles per hour faster than my walking rate, to find the average rate of each the following calculation must be performed:
35 - 14 = 21
21/6 = 3.5
35 / 3.5 = 10
14 / 3.5 = 4
So, I walk at a rate of 4 miles per hour, while the car travels at 10 miles per hour.
Answer:
(8, 5)
Step-by-step explanation:
Let's take a look at the y-intercept, (0, 5). If the axis of symmetry is x = 4, then the distance from (0, 5) is 4 units. If we reflect this point (0, 5) about the axis of symmetry x = 4, the resulting point is (8, 5). In other words, the distance from the y-intercept to the axis of symmetry is 4 units, and so the distance from the y-intercept must be 4 units plus 4 units, or 8 units.
The only answer choice that matches this is the second one: (8, 5).
Answer:
b= 4.260
Step-by-step explanation:
28^3=2165
divide both sides by 28
x^3= 2165/28
x=(2165/28)^(1/3)
x= 4.260232
