Answer:
240 people are going on the field trip.
Step-by-step explanation:
As per the statement each school bus is going on the field trip it holds 36 students and 4 adults.
Then;
total number of people in each bus = 36 students + 4 adults = 40
Also, they are having 6 filled buses on the filed trip so,
total number of people on the filed trip is equal to the 6 times of each number of people in each bus
i.e,
Total number of people on the filed trip =
Therefore, 240 people are going on the field trip.
Answer:
(x-9)(x-3)
Step-by-step explanation:
multiply -9 and -3 to get 27, add to get -12
Answer:
3a =1/4
3b = 3/13
4a = 4/9
4b = 2/3
5a = 3/8
5b = 3/11
6a = 1/4
6b = 9/13
7a = 3/11
7b = 6/19
8a = 1/9
8b = 2/11
Step-by-step explanation:
Either divide by 2 or any of the factors of both the numbers
Answer:
D) {-1}
Step-by-step explanation:
A rational expression is "not defined" when its denominator is zero. Hence to find values of x that make the expression "not defined," you solve the equation ...
denominator = 0
2x +2 = 0 . . . . . . put the actual denominator into the equation
x + 1 = 0 . . . . . divide by 2
x = -1 . . . . . . . . subtract 1
The expression is "not defined" for x in the set {-1}.
Answer:
The ratio of their surface areas would 1:9 and the ratio of their volumes would be 1:27
Step-by-step explanation:
Given Info: The sides of two cubes are in ratio of 1:3. We can assign one square x and the other square 3x.
We know that the area of a square is its side squared, and that a cube has 6 sides. So thus if we assign one side of the cube x we can assume that surface area is 6x^2:
Surface Area of Cube #1= 6x^2
Surface Area of Cube #2= 6((3x)^2) = 6(9x^2) = 54x^2
Ratio of Surface Area: 6x^2 : 54x^2 = 6:54 = 1:9
Now for the volume we know that it is equivalent to one side cubed. So after assigning x to one cube, we can assume that volume would be x^3.
Volume of Cube #1= x^3
Volume of Cube #2= (3x)^3 = 27x^3
Ratio of Volume: x^3: 27x^3 = 1:27
Hope this helps!
