Listed are the distances traveled by four cars and the time it took each car to cover that distance. Identify which cars traveled at the same speed.
Car 1 and car 3 have the same speed.
What is division?Math operations include division as one of its types. This technique involves splitting the phrases or numbers into the same amount of components.
To find which cars traveled at the same speed, we need to calculate the speed of each car. We can do this by dividing the distance traveled by the time it took to cover that distance.
For example, car 1 traveled 140 miles in 2 hours, so its speed was:
Speed of Car 1 = Distance of Car 1 / Time of Car 1 = 140/2 = 70 miles per hour.
Similarly, we can calculate the speed of each car using the given data. When we do this, we get:
Speed of Car 1 = 70 mph
Speed of Car 2 = 80 mph
Speed of Car 3 = 70 mph
Speed of Car 4 = 50 mph
We can see that Car 1 and Car 3 traveled at the same speed, which was 70 miles per hour. Therefore, the answer is that Cars 1 and 3 traveled at the same speed.

Terrance has one fewer sibling than Casey. Kolbie has three more siblings than Terrance
Final answer:
By setting up simple equations based on the given statements, we can determine the relative number of siblings that Terrance, Casey, and Kolbie have.
Explanation:
Based on the provided statements, we can set up a system of simple algebraic equations to solve for the number of siblings each person has. Let's assume Casey has C siblings. According to the given information:
Terrance has one fewer sibling than Casey, which can be represented as T = C - 1.
Kolbie has three more siblings than Terrance, which can be represented as K = T + 3.
Therefore, Kolbie's equation becomes K = (C - 1) + 3 or K = C + 2 after simplifying. Through these relationships, we can understand the relative number of siblings each individual has.
In health class, students record the weights of the sandwiches they have for lunch. The weights are shown in the line plot below. What is the average weight of one sandwich?
The mean of the value of a data is the sum of the data divided by the sample size. The average weight of one sandwich is 3/10
How to calculate the mean of data?The mean of the value of a data is the sum of the data divided by the sample size.
Mean = sum/sample size
Find the mean
Sum = 1/8 + 1/8 + 4(1/4) + 2(3/8) + 2(1/2)
Sum = 1/4 + 1+ 3/4 + 1
Sum = 3
Sample size = 10
Mean = 3/10
Hence the average weight of one sandwich is 3/10

What is the difference in volume between the prism and the storage container?
Enter your answer in the box as a simplified mixed number or a decimal.
Answer:
The answer would be 4 1/4
Step-by-step explanation:
The difference in volume between the prism and the storage container is 68,580 cubic inches.
What is Three dimensional shape?a three dimensional shape can be defined as a solid figure or an object or shape that has three dimensions—length, width, and height.
The volume of the rectangular prism is:
V = l × w × h
= 312 in × 312 in × 7 in
= 68,670 in³
The volume of the storage container is given as 90 cubic inches.
The difference in volume between the prism and the storage container is:
68,670 in³ - 90 in³ = 68,580 in³
Therefore, the difference in volume between the prism and the storage container is 68,580 cubic inches.

Arnold has been given a 6 foot by 6 foot sheet of cardboard to make an open box by cutting an equal size square from each corner, folding up the resulting flaps, and taping at the corners. Your task is to label dimensions on a sketch with same size variable cut from each corner.
Arnold creates an open box by cutting squares of size x from each corner of a 6x6 feet cardboard sheet and folding up the flaps, resulting in a box with a base of (6 - 2x) by (6 - 2x) feet and height x feet.
Explanation:To create an open box from a 6 foot by 6 foot sheet of cardboard, Arnold needs to cut squares of equal size from each corner. To represent this action, consider a square of x feet being cut out from each corner. The new dimensions of the cardboard, once the squares are removed, will measure (6 - 2x) feet by (6 - 2x) feet, with x representing the length of each side of the square cut-outs.
When Arnold folds the flaps up to form the sides of the box, the dimensions of the base will be (6 - 2x) feet by (6 - 2x) feet, and the height of the box will be x feet. The largest size for x is 3 feet, but that would result in no base for the box at all, so x must be less than 3 feet. The volume of the box can be calculated as V = x(6 - 2x)2. To maximize the volume, Arnold could use calculus to find the maximum value for V based on x within the range of 0 to 3 feet.

It is Jamie’s birthday and her mom just bought her an Xbox. She’s trying to find the surface area of the box so she can determine how much wrapping paper to use. The box is 24 inches long 12 inches wide and 10 launch is high what is the surface area of Jamie’s new Xbox?
The dimensions of the box are given 24 inches long, 12 inches wide, and 10 inches high. The box is in the shape of a rectangular prism.
We know the formula of surface area of rectangular prism is given by :-
[tex] Surface\;\; area = 2*(lw+wh+hl) [/tex]
where l is length, w is width, and h is height of the rectangular prism.
We can plug the given values l = 24, w = 12, and h = 10 into the formula and solve it for answer.
Surface area = 2 x (24x12 + 12x10 + 10x24)
Surface area = 2 x (288 + 120 + 240)
Surface area = 2 x 648
Surface area = 1296 squared inches.
So she needs 1296 squared inches of wrapping paper.
Hence, the final answer is 1296 squared inches.

On average, 75% of the days in Henderson county are sunny, with little or no cloud cover. Describe a model that you could use to find experimental probability of sunny days each day for a week in Henderson county.
Complete the work to determine the value of a. Use the law of sines: . Substitute: . Cross multiply: 8sin(45°) = asin(77°). Solve for a and round to the nearest hundredth: a ≈ .
The value of a is 5.81 to the nearest hundredth.
What is the Law of Sines?The ratios of a triangle's side lengths to each of its opposite angles are related by the law of sines. There is no change in this ratio for the three sides or the opposing angles.
Using the law of sines, we have:
sin(45°)/a = sin(77°)/8
To solve for a, we can cross-multiply and simplify:
8sin(45°) = asin(77°)
a = (8sin(45°))/sin(77°)
Using a calculator, we get:
a ≈ 5.81 (rounded to the nearest hundredth)
Therefore, a ≈ 5.81.
