Answer:
27 students
Step-by-step explanation:
Split 18 into 2 to find 1/3. 18/2= 9
9= 1/3
18= 2/3
27= 3/3 or 1
Answer:
There are 27 students.
Step-by-step explanation:
Given that,
→ 2/3
→ 18 ÷ 2
→ 9 = 1/3
Now the number of students are,
→ x = (2/3) + (1/3)
→ x = 18 + 9
→ [ x = 27 ]
Hence, there are 27 students.

marine biologist captured and tagged 12 seals near Avila Beach. Recapture results found that 27% of the seals were tagged. Approximately how many seals are near Avila Beach
Based on the number of seals that were tagged near Avila Beach, the approximate number of seals near Avila Beach is 44 seals
How many seals are there?The number of seals near Avila beach can be said to be x. If it is x, then the formula is:
12 = 27% x ×
27%x = 12
0.27x = 12
Solving for x then gives:
x = 12 / 0.27
x = 44.44
= 44 seals
In conclusion, there are approximately 44 seals near Avila beach.

Applying the triangle proportionality theorem, the length of line EC is: 7.2 units.
How to Apply the Triangle Proportionality Theorem?Since lines AC and DE are parallel to each other in the triangle, and DE intersects sides AB and AC, then we would have the following proportion based on the triangle proportionality theorem:
BD/DA = CE/EA
BD = 18 units
DA = 15 units
CE = ?
EA = 6 units
Plug in the values
18/15 = CE/6
(18)(6) = (CE)(15)
108 = CE(15)
Divide both sides by 15
108/15 = CE(15)/15
7.2 = CE
EC = 7.2 units
Therefore, applying the triangle proportionality theorem, the length of line EC is: 7.2 units.

Left-handedness is ________ common than usual among mathematicians and ________ common than usual among artist
Left-handedness is _more_______ common than usual among mathematicians and ___more_____ common than usual among artist
The relationship between handedness and mathematical ability is still highly controversial.
While some researchers have claimed that left-handers are gifted in mathematics and strong right-handers perform the worst in mathematical tasks, others have more recently proposed that mixed-handers are the most disadvantaged group.
However, the studies in the field differ with regard to the ages and the gender of the participants, and the type of mathematical ability assessed.
To disentangle these discrepancies, we conducted five studies in several Italian schools (total participants: N = 2,314), involving students of different ages (six to seventeen) and a range of mathematical tasks.
The results show that (a) linear and quadratic functions are insufficient for capturing the link between handedness and mathematical ability; (b) the percentage of variance in mathematics scores explained by handedness was larger than in previous studies.
The last theory drawing a causal link from handedness to mathematical ability through cognition is the hemispheric indecision hypothesis.

What is intersection of planes?In geometry, a plane is a flat plate which extends in all directions to infinity.
Intersecting planes are non-parallel planes that always intersect in a straight line.The two planes cannot cross more than one line.A good illustration of intersecting planes is the two connecting borders, the binding side of a book, where all of the papers (planes) meet.Now, as per the question;
Consider the following equation.
y = 1 denotes a vertical plane in the xy plane.
Z = 7 denotes a horizontal plane parallel to the xy plane.
Both planes intersect and are perpendicular to each other.
y = 1 and z=7 is the intersection of two plans where x is zero and y = 1 and z = 7.

Quadrilateral B is a scaled copy of quadrilateral A.
Its shortest side is 5 units long.
What is the scale factor from A to B?
By using the concept of dilation, we find that scale factor from A to B is equal to l' / 5, where l' is the length of the shortest side of the quadrilateral B.
What is the scale factor between two quadrilaterals?
Scale factor is a key variable used to dilate lengths and distances by rigid transformations. Then, the length of the shortest side of the quadrilateral B is equal to the product of the scale factor and the length of the shortest side of the quadrilateral A. Mathematically speaking, this kind of rigid transformation is represented by the following formula:
r = l' / l
Where:
r - Scale factorl - Length of the shortest side of the quadrilateral A.l' - Length of the shortest side of the quadrilateral B.If we know that l = 5, then the length of the shortest side of the quadrilateral B is equal to the following linear equation:
l' = 5 · r

Two shops rent kayaks for a rental fee plus a fee per hour. How many hours must a kayak be rented for the total costs to be the same? Shop A Rental fee: $8 Hourly fee: $3 Shop B Rental fee: $3 Hourly fee: $4 The total costs are the same when a kayak is rented for hours.
The total costs are the same when a kayak is rented for 5 hours
How do we determine the hours that both have the same costs?
The hours that both shops have the same cost is determined by equating the total cost in shop A to the total cost in shop B, in short, we need to first of all , model the total cost in each shop based on the straight-line equation formula shown below since the total cost is made of fixed charge and variable charge
y=a+bx
y=total cost
a=fixed charge for each shop
b=hourly fee
x=number of hours
Shop A:
total cost=8+3x

The hours when the cost of renting the kayaks would be the same is 5 hours.
The total cost of renting a kayak is $23.
When would the total cost be equal?The equation that can be used to represent the total cost of renting a kayak is a linear function. A linear equation is an equation whose graph is a straight line. A linear equation increases by a predetermined constant. An example of a linear equation is x + 2.
The form that the equation would be is:
Total cost = rental fee + (hourly fee x number of hours)
Total cost at Shop A = $8 + $3h
Total cost Shop B = $3 + $4h
Where h is the number of hours the kayak was rented.
When the total costs are equal, the two above equations would be equal.
$3 + $4h = $8 + $3h
Combine similar terms: $4h - $3h= $8 - $3
Add similar terms together: h = 5 hours
Total cost = $3 + $4(5)
$3 + $20 = $23
