4 freight cars can be filled by 120 scoops of excavator having a total mass of 156 tons and a volume of 3120 ft³.
What do we mean by volume or capacity of a substance?In three-dimensional space, volume refers to the entire amount of space occupied by an item. Capacity refers to an object's capacity to contain, absorb, or accept anything (such as a solid material, gas, or liquid).
What do we mean by the mass of a substance?The amount of matter in a substance or object is measured by its mass.
How do we solve the given question?In the question, we are given that the scoop of an excavator holds 26 ft³of sand.
We are asked if the capacity of a freight car is 39 tons of sand, then how many freight cars can be filled with 120 scoops.
We are also informed that 1 ft³ of sand weighs 0.05 tons.
We first find the mass of sand in one scoop of an excavator.
The volume of sand in one scoop of an excavator = 26 ft³.
Mass of 1 ft³ of sand = 0.05 tons.
∴ Mass of 26 ft³ of sand, that is, the mass of sand in one scoop of an excavator = 26*0.05 tons = 1.3 tons.
∴ Mass of 120 scoops = 120*1.3 tons = 156 tons.
The capacity of one freight car = 39 tons
∴ Number of freight cars in 156 tons = 156/39 = 4.
∴ 4 freight cars can be filled by 120 scoops of excavator having a total mass of 156 tons and a volume of 3120 ft³.

27. The fifth and thirteenth terms of an arithmetic sequence are 5 and 77 , respectively. Find the first term and the tenth term.
Answer:
if the first term is 13, the second will be 13+x, the third 13+2x and so on, the tenth term will be 13+9x=40 9x = 27 x = 3 so the difference between the terms is 3 the sum of the first 10 terms is 13*10 + (x+2x+…+9x) = 130 + 45x = 130 + 45*3 = 130 + 135 = 265

A letter tile is selected at random from the tiles shown below. What is the sample space?
Answer:
the answer is d cause sample space means all the possible outcomes
Answer:
C) A, B, F, K, S
Step-by-step explanation:
The sample space is the range of values a random variable may have. In this process, the random variable will have the value of one of the letters shown. That is, it will be one of {A, B, F, K, S}.
The sample space is A, B, F, K, S.
_____
Additional comment
If the letters are selected at random with uniform probability, the probability of any given outcome is the ratio of the number of times that letter appears in the population to the total number of letters.
For example, p(A) = 3/9 = 1/3.

PLEASE HELP QUICK. (WIlL GIVE BRAINLIST) Erina runs 200 meters each day during the first week of her training. She plans to increase the distance she runs each week. Erina's training goal is to run 150% of the distance she ran each day in the previous week. She will run the same distance each day in a week. There are approximately 27.34 yards in 25 meters. If Erina meets her goal, how many yards will Erina run each day in the third week of her training? Round the answer to the nearest hundredth. Enter the answer in the box _____ yards
During the first week of her training, she runs 200 meters. On the second week, she plans to run 50% more.
Now, how do you calculate this?
To increase 200 meters by 50%, multiply by 1.5
The second week she pans to run 450 meters.
Since there are only 3 weeks, do it again!
The thrid week, she plans to run 675 meters.
Since she runs the same ammount each day of the week, the calculation is simple.
7(200) + 7(450) + 7(675)
In these three weeks, she runs 9275 meters.
OR, she runs 10143.26 yards.

To find the product of the fractions 3/11 and 3 1/4,
we need to convert the mixed number 3 1/4 to an improper fraction and then multiply the two fractions.
Step 1: Convert the mixed number to an improper fraction.
3 1/4 = (4 * 3 + 1) / 4 = 13/4
Step 2: Multiply the two fractions.
(3/11) * (13/4)
= (3 * 13) / (11 * 4)
= 39 / 44

5. SereN and Visala had a combined total of $180. SereN then gave Visala $20, and then Visala gave SereN a quarter of the money Visala had. After this, they each had the same amount. How much money did SereN start with?
The amount of money seren had will be $132.
what is a linear equation?
It is defined as the linear relation between two variables, if we plot the graph of the linear equation we will get a straight line.
Given that:-
Seren and Visala had a combined total of $180Seren then gave Visala $20, and then Visala gave Seren a quarter of the money Visala had. After this, they each had the same amount.
The solution will be done by making an equation:-
According to the first condition:-
S + V = $180
Now from the second condition:-
S - 20 + { ( v + 20 ) / 4 ) } = 180
Since S = v then:-
S - 20 + { ( S + 20 ) / 4 ) } = 180
S = $132
Therefore the amount of money seren had will be $132.

Below is the graph of y equation y=-|x-2|+3. Use this graph to find all values of x given each statement. a) -|x-2|+3>0 b) -|x-2|+3<0 c) -|x-2|+3=0
Answer:
The answer is C) - |x - 2| + 3 = 0
Step-by-step explanation:
a) - |x - 2| + 3 > 0
The greater than means something above the graph.
b) - |x - 2| + 3 < 0
The less than means something below the graph.
c) - |x - 2| + 3 = 0
The zero doesn't do anything.
y = - a |x - h| + k = 0
(h,k) is the origin.
h is shift left/right, h = 2 so shift right 2.
k is shift up/down, k = 3 so shift up 3.
The a, affects the y-values which cause the graph to reflect across the x-axis.

Solve 6(2/3x-3)>8. The thing says the question is too short and to add at least 20 more words so ignore this sentence, it's only to submit
Answer:
[tex]6(\frac{2x}{3} -3) > 8\\[/tex]
Solve brackets
6(0.66x-3)>8
Multiply 6 with values in the bracket
So, 6x0.66x and 6x-3
4x- 18> 8
Since 4x and 18 are unlike terms, we will take 18 onto the other side, thus:
4x>8+18
4x>26
Now to find the value of x, divide 4 on B.S
