Answer:
35/100
Step-by-step explanation:
You have to find how many juniors there are, so if you add 13, 20, and 2 you get 35. For the denominator you have to find the total number of students, so just add all of the numbers together to get 100. So there is a 35/100 chance that a randomly selected student is a junior.

if f(x)=-3x-5 and g(x)=4x-2 find (f-g) (x)
If f(x)=-3x-5 and g(x)=4x-2, then the value of (f-g)(x) is -7x-3.
The given functions are f(x)=-3x-5 and g(x)=4x-2.
We need to find the value of (f-g)(x)
What is a function?In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function.
Now, (f-g)(x)=f(x)-g(x)=(-3x-5)-(4x-2)
= -3x-5-4x+2 = (-3x-4x)+(-5 + 2)
= -7x-3
Therefore, the value of (f-g) (x) is -7x-3.

Mrs Phillips is going to cover the floor with floor boards.
One pack of floor boards will cover 2.5 m².
How many packs of floor boards does she need?
You must show your working.
Diagram NOT
accurately drawn
Mrs. Phillips needs to buy 8 packs of floor boards
In contrast to a square, a rectangle is a planar figure having four equal neighboring sides, four straight sides, and four right angles. An enclosed 2-D form called a rectangle has four sides, four corners, and four right angles (90°). A rectangle has equal and parallel opposing sides. A rectangle has two dimensions—length and width—because it is a two-dimensional form. The rectangle's longer side is its length, while its shorter side is its breadth.
As per the figure attached Mrs. Phillips floor plan can divided into two rectangles
The area of rectangle is as follow:
Area = length(l) x Width(w)
Area of part 1 will be:
A = 6 x 2 = 12 m²
Area of part 2 will be :
a = 3 x 2 = 6 m²
Total area of floor = A + a
Total area of floor = 12 + 6
Total area of floor = 18 m²
Given one pack of floor boards will cover 2.5 m².
So total pack of floor block needed will be as follow:
Total pack of floor block = Total area of floor/Area covered by one pack of floor boards
Total pack of floor block = 18/2.5
Total pack of floor block = 7.2 packs ≈ 8 packs

The center of a circle is at the origin on a coordinate grid. A line with a positive slope intersects the circle at (0, 7). Which statement must be true?
The true statement is the circle has the radius equal to 7.
What is Equation of circle?The general equation for a circle is (x-h)² + (y-k)² = r², where ( h, k ) is the center and r is the radius.
As, standard form of equation of circle is
(x-h)² + (y-k)² = r²
At origin, equation of circle will be
(0-h)² + (0-k)² = r²
r² = x² + y²

A. (3, 0)
B. (4, 2)
C. (5, 3)
D. (0, 6)
E. (4, 4)
F. (1, 5)
The distance between the points (0, 0) and (0, 6) on the coordinate plane will be 6 units. Then the correct option is D.
What is the distance between two points?The shortest distance (length of the straight line segment's length connecting both given points) between points (p, q) and (x, y) is:
D² = (x – p)² + (y – q)²
Point M is 6 units away from the origin.
Take option D assuming correct, then the point will be (0, 6)
Then the distance between the points will be
D² = (0 - 0)² + (6 - 0)²
D² = 0² + 6²
D² = 0 + 36
D² = 36
D = 6 units

The table and the graph below each show a different relationship between the same two variables, x and y.
How much more would the value of y be on the graph than its value in the table when x = 12?
Answer:
240
Step-by-step explanation:
Using the straight line formula; y=mx+c, take two points, for example, (4, 80) and (5, 100)
m=change in y/change in x, so;
m=(100-80)/(5-4)= 20
Take point (4, 80)
80=20×4 + c
80-80=c=0
so y=20x
y=20×12=240

You own a catering company and are in charge of an engagement party. There are two dinners: a chicken dish, which costs $40, and a lobster dish, which costs $70. The 250 party guests have ordered their meals in advance, and the total cost to prepare the dinner is $13 570. How many of each type of dinner are you preparing?
The number of chicken dish is 131 dishes while the number of lobster dishes is 119 dishes
How to find the number of each type of dish.Let
x = number of chicken dish and y = number of lobster dishHow to determine the equations for the linear systemSince it cost $40 per dish for chicken dish, the total cost of chicken dish is 40x.
Also, since it cost $70 per dish for lobster dish, the total cost of lobster dish is 70y
So, the total cost of dish is T = 40x + 70y
Also, we know that the total cost of dish is $13,570.
So, 40x + 70y = 13570 (1)
Also, there are going to be 250 guest at the dinner and thus 250 dishes.
So, the total number of dishes is x + y = 250
So, x + y = 250 (2)
So, the equations of the linear system are
40x + 70y = 13570 (1)
x + y = 250 (2)
How to determine the solution for the linear systemSince
40x + 70y = 13570 (1)
x + y = 250 (2)
From (2), x = 250 - y
Substituting x into (1), we have
40x + 70y = 13570 (1)
40(250 - y) + 70y = 13570 (1)
10000 - 40y + 70y = 13570
30y = 13570 - 10000
30y = 3570
y = 3570/30
y = 119
Substituting y = 119 into x, we have
x = 250 - y
x = 250 - 119
x = 131
Therefore, the number of chicken dish is 131 dishes while the number of lobster dishes is 119 dishes
