Answer:
15
Step-by-step explanation:
We know according to the figure that 9^2+12^2 = z^2,
as a result, we know that z^2 = 225
and z = 15
Another method is to recognize that this figure is similar to a 3-4-5 triangle. According to the converse of the Hypotenuse-Leg theorem, we get that the third length of the triangle is 15

Function or not a Function
Answers
Answer:
Function; Not a function
Step-by-step explanation:
Write the ordered pair in the first set (x, y): (1, 11), (2, 7) , (3, 2)
Write the ordered pair in the second set (x, y): (1, 3), (1, 4), (2, 4) , (3, 2)
The first set in a function because no ordered pair has the same x value.
The second set in not a function because the x value is the same in two of the ordered pairs.

Hello!
Judging by the question you have provided I have come up with the correct solution:
y=25x+175
Step-by-step explanation:
The way I came up with the solution is by understanding how to write the correct equation using the correct variables in the correct places.
In the equation y=mx+b, the variable "b" will always be an independent variable.
The independent variable of Candace equation is "175 gallons". This is because this amount does not change throughout the entire equation.
Next, the variable "m" will always be a dependent variable.
The dependent variable of the Candace equation is "25 gallons". This is because this variable is effected by "x amount of hours".
So when you input these given variables in the correct places you get:
y=25x+175
In all but the worst weather, Sarah and three coworkers meet each day at 4:45 to walk the river trail behind their office building. The four coworkers are an example of a(n)
Answers
The coworkers meet each day after the official work hours, then they are an example of an informal group. An informal group is a group made up of people to discuss non-official matters.
The two major types of groups relating to official function are formal and informal. Formal groups are groups formed by the management for a specific or official purpose. This type of groups discuss official matters and issues, and probably are dissolved after achieving the purpose of forming the group.
Informal groups are groups formed by a set of workers( which may sometimes include an external person) formed to discuss non-official maters. The members meet at the non-official hours to deliberate, gist or discuss personal and other relating issues.
Therefore, the four coworkers mentioned in the given question are an example of an informal group.

What is the inverse of the function f(x)=-4x+2
Answers
Answer:
The inverse of f is [tex]f^{-1}[/tex] = (x -2)/4
Step-by-step explanation:
To find the inverse of f(x) = 4x + 2 , interchange the variables and solve for y.
Rewrite f(x) = 4x + 2 as x = 4y + 2 then solve for y
x -2 = 4y
(x - 2)/4 = y

You used 5 cups of flour to bake 80 cookies. How many cups of flour do you need if you bake 144 cookies?
Answers
Answer:
9 cups
Step-by-step explanation:
We can write a ratio to solve
5 cups x cups
------------ = ----------------
80 cookies 144 cookies
Using cross products
5 * 144 = 80x
720 = 80x
Divide by 80
720/80 = 80x/80
9=x
Answer:
7 1/5 cups of flour to mae 144 cookies
Step-by-step explanation:
80/5 = 20 cookies per cup of flour
so 20x7 = 140 and then you still need four more so take the four and another cup of flour and divide the 20 by 4 then you get 5 thus you 7 and 1/5ths cups
What is the area of a rectangle with vertices at (0, −4), (−1, −3) , (2, 0), and (3, −1)? Enter your answer in the box. units²

Step-by-step explanation:
Answer:
Area of the rectangle is [tex]6u^{2}[/tex]
How to find area of rectangle if the vertices are given:
Let the vertices be or the given vertices:
A [0,-4]
B [-1,-3]
C [2,0]
D [3,-1]
Area of rectangle is twice the area of triangle, i.e. if the area of rectangle is ABCD and area of triangle is ABC.
Area of triangle is given by determinant:
Area of triangle = 1/2 [x1, y1]
1/2 [x2, y2]
1/2 [x3, y3]
1/2 [x4,y4]
Putting all the values in this format we will get :
Area of triangle = 1/2 [0×-4]
[-1×-3]
[2×0]
Because we have assume 0 as x1 and -4 as y2
-1 as x2 and -3 as y2
2 as x3 and 0 as y3
By solving that equation we will get:
1/2[ −4 0 1]
[−3,1,1]
[0,−2,1]
=1/2(−4⋅(1⋅1+1⋅2)−0+1⋅(6−0))
=1/2|-6|= [tex]3u^{2}[/tex]
= -3=[tex]3u^{2}[/tex]
= [tex]6u^{2}[/tex]
In a two-dimensional plane, a triangle's area is the space it encloses. Known for having three sides and three vertices, a triangle is a closed shape. The sum of the spaces occupied by a triangle's three sides is known as its area. Half of the product of a triangle's base and height is the usual formula for calculating its area.The area that is included within the perimeter of a flat object or figure is generally considered to be the definition of the word "area." The square units used for measuring are square meters as the standard unit (m2). There are already established formulas for calculating the area of squares, rectangles, circles, triangles, etc.

Solve this equation for the indicated variable.5b + 12c=9 for b
Answers
Answer:
b = (9 - 12c)/5 OR b = 9/5 - 12c/5
Step-by-step explanation:
5b + 12c = 9
Subtract 12c from both sides.
5b = 9 - 12c
Divide both sides by 5.
b = (9 - 12c)/5.
Divide 320 into 8 equal groups
Answers
Answer:
320 divided by 8 is 40. 40 times 8 is 320, so it works backwards.
When dividing 320 into 8 equal groups, each group would contain 40.
We have to divide 320 into 8 equal groups.
Performing the division as
8 | 320 | 40

Two arithmetic sequences A and B both begin with 30. Sequence A has common difference 9 and sequence B has common difference 4. What is the difference between the 51st term of A and the 51st term of B?
Answers
The n-th term of an arithmetic sequence with first term a and common difference d is
a + (n - 1) d
So, the 51st term of A is
30 + 9 (51 - 1) = 480
while the 51st term of B is
30 + 4 (51 - 1) = 230
The difference between them 480 - 230 = 250.
