A science museum has an average of 424 visitors each day. The museum is open every day. Over a two-week period, how many people visit the museum?
Answer:
5936 people
Step-by-step explanation:
Answer: 5936 people visit the museum in an average of 2 weeks.
Step by Step Explanation:
There is 7 days in a week. To find the amount of day in two weeks multiply the number of days in a week by 2.
7x2=14
Next, multiply 424 by the number of days in two weeks.
424x14= 5936
The answer is, 5936 people visit the museum in an average of 2 weeks.

The sum of my three digits is 13. My first digit
is 2 and my last digit is a multiple of 5. What
number am I?
Answer:
Step-by-step explanation:
Comment
The sum of the digits is 13.
The first digit is 2
The last digit is 0 or 5
Can it be zero?
2 + _ + 0 = 13
2 + 0 _ x = 13 Subtract 2 from both sides
2 - 2 + 0 + x = 13 - 2 Combine
x = 11
No there is no such thing as a digit is value is 11. So the last digit is 5
2 + __ + 5 = 13
7 + x = 13 Subtract 7 from both sides
7-7 + x = 13 - 7 Combine
x = 6
The middle number is 6

Don and Ana are driving to their vacation destination. Upon entering the freeway they began driving at a constant rate of 60 miles an hour. Don noticed that 3 hours into the trip they were 650 miles from the destination.
How far from their destination will they be 3.7 hours since entering the freeway?
How far from their destination were they 2.3 hours since entering the freeway?
To solve the problem we must know about Speed, distance, and Time.
What are Speed, distance, and Time?We know that sped, distance, and time all are in a relationship to each other. this relationship can be given as,
[tex]\rm{Speed = \dfrac{Distance}{Time}[/tex]
Given to us
Speed = 60 miles an hour
Don noticed that 3 hours into the trip they were 650 miles from the destination.
Distance traveled by them in 3 hoursWe know that Don and Ana are traveling at a constant speed and they are traveling for 3 hours.
[tex]\rm Distance= \rm speed \times Time[/tex]
[tex]\rm Distance = 60 \times 3 = 180\rm\ miles[/tex]
Thus, Distance traveled by them in 3 hours is 180 miles.
Total Distance from their destinationWe know that Don and Ana are traveling on the freeway for the past 3 hours and they are still 650 miles away, therefore,
Total Distance from their destination
= Distance traveled by them in 3 hours + 650 miles
= 180 miles + 650 miles
= 830 miles
Thus, the distance traveled by then is 830 miles.
A.) Distance between them and destination after 3.7 hours since entering the freeway,
Distance traveled by them = speed x 3.7
= 60 x 3.7 = 222 miles
Distance between them and the destination= Total Distance from their destination - Distance traveled by them
= 830 miles - 222 miles
= 608 miles
Thus, they are 608 miles far from their destination.
B.) Distance between them and destination after 2.3 hours since entering the freeway,
Distance traveled by them = speed x 2.3
= 60 x 2.3 = 138 miles
Distance between them and the destination= Total Distance from their destination - Distance traveled by them
= 830 miles - 138 miles
= 692 miles
Thus, they are 692 miles far from their destination.

Which expression is not equivalent to 8 + (n - 4)?
1. n + 4
2. (8 - 4) + n
3. (8 + n) - 4
4. 12 + n
Answer:
D. 12 + n
Step-by-step explanation:
To solve this question we have to simplify each equation 1 by 1 :
First, let us do the equation in the problem:
8 + (n - 4) = n +4
Now let us review the answers:
A. Is equivalent because 8 + (n - 4) = n + 4
B. Is equivalent because (8 - 4) + n = n + 4
C. Is equivalent because (8 + n) - 4 = n + 4
and D. is not equivalent because obviously 12 + n does not equal n + 4

Joe wants to fence a rectangular pen for his goats. The length of the pen should be at least 60
ft, and the distance around should be no more than 260 ft. Which system of inequalities and
graph represent the possible dimensions of the pen?
Answer:
y>60
2*x+2*x<260
it's the only one that works
Step-by-step explanation:
The system of inequalities is x ≥ 60 and 2x + 2y ≤ 260.
The graph is given below.
What is inequality?It shows a relationship between two numbers or two expressions.
There are commonly used four inequalities:
Less than = <
Greater than = >
Less than and equal = ≤
Greater than and equal = ≥
We have,
Length of the rectangular pen = x
Width of the rectangular pen = y
Now,
x ≥ 60 _____(1)
Perimeter = 260
2 (x + y) ≤ 260
2x + 2y ≤ 260 _____(2)
The graph of (1) and (2) are given below.
Thus,
The system of inequalities is x ≥ 60 and 2x + 2y ≤ 260.
The graph is given below.

Find the area of the isosceles triangle formed by points of intersection of the parabolas y=-x2+9 and y=2x2+3 and the origin.
Answer:
10
Step-by-step explanation:
*I’m assuming that you meant y = 2x^2-3 because that is what my RSM problem was and it was exactly the same problem other than that.* First you want to find the points of intersection of the two parabolas. You can choose to graph them or do any other method. Anyways, the points of intersection are: (2,5) and (-2,5). You now want to add (0,0). So obviously (2,5) to (-2,5) is the base and it is 4 units. The height is 0 to 5 which is 5 units. Do (4*5)/2 and you get 10. Hope this helped you with your RSM and let me know if I assumed correctly.
