Answer:
none of the above?
Step-by-step explanation:
so the angles of the triangles are A1+A2+A3=360
so (4x+7)+(11x-9)+32=360
combine like terms
15x+30=360
isolate the variable
15x=330
x=22
angle ACB is 4x+7
4(22)+7=
88+7=
95
The correct answer is B. A structure that is used to represent a complex system
Explanation:
A scientific model is a structure or set of concepts that aim at representing a natural phenomenon or system. This means a scientific model is not created to be an exact copy of the system but rather to act as a representation, which helps scientists to explain or understand the functions and elements of a system. For example, by creating a model of a specific ecosystem, scientists can better understand the interactions between living organisms in the ecosystem, even though the model is not an exact model of the real ecosystem. According to this, a model in science is "A structure that is used to represent a complex system"
Answer:
300
Step-by-step explanation:
5÷1500=300
5×3=15
15-15=0
0000
300×5=1500
sorry this the best way I know how to explain
Answer:
Step 1: Calculate. We calculate the square root of 62 to be: √62 = 7.87400787401181.
Step 2: Reduce. 7.87.
Step 3: Round. Round 7.87 so you only have one digit after the decimal point to get the answer: 7.9.
