Answer:
418.88 ~ 419
Step-by-step explanation:
100℅ = 476
12℅. = x
x = 12℅ × 476/100℅
x = 57.12
so the population increased by 57.12 students
476-57.12=418.88
Answer:
B and D
Step-by-step explanation:
It is an Acute triangle because all the angles are acute, meaning all the angles are less than 90°.
It is an Equilateral triangle because all the sides are equal. Shown in the picture, the lines going through all the sides mean that they are all the same length.
Step-by-step explanation:
multiply the first bracket with the second
and get -a squared -4a+3a+12
then we group like and unlike terms
so -4a+3a = -a
our new equation will be -a (squared)-a+12=0
we equals to zero to remove negative signs and it will be
a squared +a-12
then we find the factors.
And our factors are 3a-4a
=a squared +3a-4a-12=0
We factorise and answer will be
(a+3) (a-4)=0
so a = -3 or 4
After solving the linear programming problem, we get the answer as <u>250</u>.
What is linear programming?
When a linear function is <u>exposed to multiple restrictions, </u><u>linear </u><u>programming maximizes or minimizes the function</u>. This method determines the best way to use the resources that are currently available and aids managers in using the process to <u>make </u><u>decisions </u><u>about the most efficient use of scarce resources, such as money, time, materials, and machinery</u>. Linear programming has been useful for guiding quantitative decisions in business planning, industrial engineering, and—to a lesser extent—in the social and physical sciences.
Solution explained:
x=3, y=4 P(3,4) Coordinates of the solution point
x=4, y=3 Q(4,3)
Coordinates of the simultaneous eqs.
x=14/3, y=8/3
Putting the values of x and y in the equation P = 30x + 40y and calculating we get
P(P) = 250, P(Q) = 240, P(R) = 246.67
So, the answer is 250
