Answers: See each part below.
1) The scale factor on Map 1 is 1cm = 2 km. It is given in the key in the bottom right corner.
2) The length of the trail would be 16 km. Since each cm is 2 km, we multiply the 8 by 2 to get a total of 16.
3) The scale factor from the first map to the second map is 0.75. To find this we can write and solve the following equation to determine the change from Map 1 to Map 2.
8k = 6
k = 0.75
4) To find the lengths of the sides of the landmark, just change the mm into cm and use the scale factor for each.
5 mm is 0.5 cm. 0.5 x 2 = 1 km
3 mm is 0.3 cm. 0.3 x 2 = 0.6 km
4 mm is 0.4 cm. 0.4 x 2 = 0.8 km
Answer:
<h3>1404</h3>
Step-by-step explanation:
To use the order of operations stands for (Parenthesis, Exponents, Multiply, Divide, Add, and Subtract) left to right. Please Excuse My Dear Aunt Sally!
BOMDAS stands for (Brackets, Of, Multiply, Divide, Add, and Subtract) from left to right.
First, do parenthesis.
52*(4+23)
4+23=27
52*27
Then, multiply.
52*27=1404
1404
The correct answer is 1404.
Answer:
And from the 532 adults in the sample we know that 174 adults said that they were not confident that the food they eat in country A is safe, and we can notate that with:
We can estimate the proportion of adults who said that they are not confident that the food they eat in country A is safe with this formula:
And the complement rule is given by:
And this proportion represent the proportion of adults who NOT said that they are not confident that the food they eat in country A
Step-by-step explanation:
For this case we have the following info given from a survey.
The total sample size is 532 so then we have:

Answer:
The union of two sets is guaranteed to result in an equal or larger set than if they were intersected.
This only makes sense because intersecting sets is exceptional, only values that already exist in both sets are in the result. Whereas a union of two sets gives you all of the content of both.
The only time when an intersection is even equal to a union is when the two sets are identical. If they aren't then the intersection will be smaller.
Seven plus y equals nine plus five
7+y=14
y=7
