Answer: 12
Step-by-step explanation:
The constant of the expression is 12.
What is a constant?'A constant is a value or number that never changes in expression that is it's constantly the same.'
According to the given problem,
In the expression 3k + 12 , k is a variable. A variable is a quantity that may change with respect to the mathematical criteria.
If k = 1, the value of the expression is (3 × 1) + 12 = 15
k =2, the value is (3 × 2) + 12 = 18
But we can see that no matter the value of k is, the expression has to be added with 12.
Hence, we can conclude that since the value of 12 does not change irrespective of the changing values k, the constant of this expression is 12.

A cylindrical tank of radius 2.5 feet is being drained of water at a rate of `0.25\ ft^{3}/\sec`. How fast is the height of the water decreasing?
Answer:
DONT PRESS THAT LINK
Step-by-step explanation:
The height of the water decreases at a rate of 0.012 ft/sec if a cylindrical tank of a radius of 2.5 feet is being drained of water at a rate of 0.25 ft³/sec.
What is a cylinder?In geometry, it is defined as the three-dimensional shape having two circular shapes at a distance called the height of the cylinder.
We know the volume of the cylinder is given by:
[tex]\rm V = \pi r^2 h[/tex]
It is given that:
A cylindrical tank of a radius of 2.5 feet is being drained of water at a rate of 0.25 ft³/sec
As we know,
The volume of the cylinder is given by:
V = πr²h
Let V is the water draining rate
V = 0.25 ft³/sec
The radius r = 2.5 feet
0.25 ft³/sec = π(2.5 feet)²(h)
h = [0.25/(2.5²π)] [ft³/(sec×feet²]
h = 0.012 ft/sec
Thus, the height of the water decreases at a rate of 0.012 ft/sec if a cylindrical tank of a radius of 2.5 feet is being drained of water at a rate of 0.25 ft³/sec.

The triangle below is isosceles. If ∠C≅∠B, then what is BC, in units?
Answer:
Step-by-step explanation:
If angles C and B have equal degrees then the side AC is also equal to side AB in length and you can make their equations equal as well and solve for X.
2x+16=7x+6
get X's all on same side and the constants all on the other side,
-2x +2x+16=7x+6+-2x
The X's on the left cancel out.
16=5x+6
-6+16=5x+6+-6
add -6 to each side. On the right the 6 is now cancelled out.
10=5X
divide each side by 5 to cancel out the 5
10/5= 5X/5

Answer:
2.5
Step-by-step explanation:
Let x be the number of hours both people baby sit and y be the number of hours that they each earn.
Sarah:
y = 10 + 2.5x
Carly:
y = 7.5 + 3.5x
You know that the number of hours should be the same (y).
10 + 2.5x = 7.5 + 3.5x
Evaluate and find x.
10 - 7.5 = 3.5x - 2.5x
x = 2.5

The SAT and ACT college entrance exams are taken by thousands of students each year. The mathematics portions of each of these exams produce scores that are approximately normally distributed. In recent years, SAT mathematics exam scores have averaged 480 with standard deviation 100. The average and standard deviation for ACT mathematics scores are 18 and 6, respectively. (a) An engineering school sets 560 as the minimum SAT math score for new students. What percentage of students will score below 560 in a typical year
Answer:
78.814%
Step-by-step explanation:
mean, = 480 points.
standard deviation, σ = 100 points.
If 560 is the minimum score, x = 560. We want the % of students who will score BELOW that. Use the formula for z-scores: [tex]z = \frac{x-u}{standard deviation}[/tex] to get the z score: (560-480)/(100) = 0.8.
Using a z-score table: the value under 0.8 is 78.814%.

Answer: 4 and 1/4
Step-by-step explanation:
1st question is 4-- count the points that fall above the line
2nd question is 2 out of 8, or 1 out of 4
there are only 2 players who played at least 17 matches AND scored about 5000. There are 8 players who played at LEAST 17 matches
Answers:
1. 4
2. ¼
Explanations:
1. the question is asking how many players were awarded more points than the prediction of the line of best fit (trend line), which can be translated to how many dots are above the line on the graph. 4 dots can be counted above the line
2. 8 players played at least 17 tournaments. of these 8 players, only 2 scored more than 5000 ranking points.
thus, to find the probability, we take 2 ÷ 8 = ¼
