Find the coordinates of the midpoint for line segment JK if J(-9, 5) and K(21.-7)
Answer:
(6, -1)
Step-by-step explanation:
The coordinates of the midpoint of a line is [(x₁ + x₂)/2, (y₁ + y₂)/2]. For the given line, JK where J = (-9, 5) = (x₁, y₁) and K = (21,-7) = (x₂, y₂).
So [(x₁ + x₂)/2, (y₁ + y₂)/2]
= [(-9 + 21)/2, (5 + (-7))/2]
= [12/2, (5 - 7)/2]
= [12/2, -2/2]
= (6, -1)

One thermos of hot chocolate uses 2/3 cup of cocoa powder. How many thermoses can Nelli make with 3 cups of cocoa powder?
Answer:
4 thermoses of hot chocolate
The number of thermoses that Nelli makes with 3 cups of cocoa powder will be 2.
What is Algebra?The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
It is also known as the product. If the object n is given to m times then we just simply multiply them.
One thermos of hot chocolate uses 2/3 cup of cocoa powder.
Then the number of thermoses that Nelli makes with 3 cups of cocoa powder will be given by the multiplication of 2/3 and 3.
⇒ (2/3) x 3
⇒ 2
The number of thermoses that Nelli makes with 3 cups of cocoa powder will be 2.

Is it linear or exponential
Linear is a straight line. You might have heard of Linear Function.
[tex]y = mx + b[/tex]
The equation above is slope-intercept form.
ExponentialExponential is both increasing graph and decreasing graph depending on the coefficient.
Exponential Equation
[tex]y = {a}^{x} \: \: \: (a > 0) \: \: (a \neq1)[/tex]
Exponential Graph increases when a-term is greater or equal to 1.
Exponential Graph decreases when a-term is greater than 0 but less than 1.
From the equation, it is exponential of x-term as an exponent. The equation matches with exponential form.

How many solutions are there
Answer:
Step-by-step explanation:
As given system of linear equations,
- 3х +Зу = 12у=х+ 4Hence taking 1st equation ,
-3x+3y=12

Suppose that the functions u and w are defined as follows :
u(x)= x^2+6
w(x)= \sqrt{x+9}
Find the following:
(u o w) (7) =
(w o u) 7) =
Answer:
(u o w) (7) = 22
(w o u) 7) = 8
Step-by-step explanation:
We are given:
[tex]u(x)= x^2+6\\w(x)= \sqrt{x+9}[/tex]
We need to find:
a) (u o w) (7)
First we will find (u o w) (x) and then we will find (u o w) (7)
We know that (u o w) (x) = u(w(x))
Put value of w(x) into u(x)
we have:
[tex]u(x)=x^2+6\\Put\: x =\sqrt{x+9}\\u(w(x))=(\sqrt{x+9})^2+6\\u(w(x))=x+9+6\\ u(w(x))=x+15[/tex]
Now finding (u o w) (7)
We know that: (u o w) (7) = u(w(7))
[tex]u(w(x))=x+15\\Put\:x=7\\u(w(7))=7+15\\u(w(7))=22[/tex]
So, (u o w) (7) = 22
b) (w o u) (7)
First we will find (w o u) (x) and then we will find (w o u) (7)
We know that (w o u) (x) = w(u(x))
Put value of u(x) into w(x)
we have:
[tex]w(x)= \sqrt{x+9}\\Put\:x=x^2+6\\w(u(x))= \sqrt{(x^2+6)+9}\\w(u(x))= \sqrt{x^2+6+9}\\w(u(x))= \sqrt{x^2+15}[/tex]
Now finding (w o u) (7)
We know that (w o u) (7) = w(u(7))
[tex]w(u(x))= \sqrt{x^2+15}\\Put\:x=7\\w(u(7))= \sqrt{(7)^2+15}\\w(u(7))= \sqrt{49+15}\\w(u(7))= \sqrt{64}\\w(u(7))= 8[/tex]
So, (w o u) (7) = 8

The tape diagram models the lengths of two snowboarding trails. The expert trail is 1200 meters long. How long is he beginner trail?
Answer:
300 ft long
Step-by-step explanation:
divide 1200 by 4 sense the beginners trail is one-fourth the length of the expert trail
The length of beginner trail is 300 meter long.
What is Division method?Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications. For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.
Given that;
The tape diagram models the lengths of two snowboarding trails.
And, The expert trail is 1200 meters long.
Now, The length of beginner trail is,
⇒ 1200 / 4 meter
⇒ 300 meter
Thus, We get;
⇒ The beginner trail is 300 meter long.

The cost of hiring a taxi consists of a fixed cost of $3 plus $0.5 per kilometer distance travelled. Write an expression in terms of y for hiring a taxi for y kilometers.
Answer:
The required expression is:
y = 0.5x + 3Please check the attached graph too.
Step-by-step explanation:
The slope-intercept form of the linear or line function
[tex]y = mx+b[/tex]
where
m is the rate of change or slopeb is the y-interceptIn our case,
The cost of hiring a taxi consists of a fixed cost of $3. It means the fixed cost of $3 is the initial condition.
Thus, the y-intercept b = 3
It is stated that the cost of per kilometer distance = $0.5
Thus, the rate of change or slope m = 0.5
As y represents the cost and x represents the number of kilometers.
so substituting m = 0.5 and b = 3 in the slope-intercept form of the linear or line function
y = mx+b
y = 0.5x + 3
Thus, the required expression is:
y = 0.5x + 3Please check the attached graph too.

A circular piece of wood with a diameter of 5 ft is shown below. A 2 ft square is
cut out of the middle of the piece of wood.
2 ft
What is the approximate remaining area of the wood?
O A. 21 ft2
O B. 16 ft2
O C. 18 ft2
OD 28 ft2
Answer:
16 ft²
Step-by-step explanation:
Since we're told that 2 ft diameter was cut of the board. We use the formula for hollow circle to find the area.
Area of remaining body = area of full body - area of removed body.
Area = πd²/4
Area of remaining body = (π * 5²)/4 - (π * 2²)/4
Area of remaining body = 19.64 - 3.142
Area of remaining body = 16.49 ft²
Therefore, the remaining area is then calculated into 16 ft²

Four friends are on a basketball team. During a game, each friend kept track of how many shots they attempted and how many of those attempts they made. Henry made 0.45 of his shots. Allison made 4/15 of her shots. Arthur made 8/20 of his shots. Trevor missed 58% of his shots. Which friend had the best record for the number of shots made?
Answer:
Henry has a best record for the number of shots made.
Step-by-step explanation:
It is provided that Henry made 0.45 or 45% of his shots.
And Trevor missed 58% of his shots, i.e. Trevor made 42% of his shots.
There is no information about Allison's and Arthur's probability of making the shot.
So, only based upon Henry and Trevor, it can be seen clearly that Henry has a best record for the number of shots made.

Knowing the first triangle is isosceles, and given the degree is 69.
We can find the top left angle as 180-69-69=42
42 combine with another angle to make a right angle
90-42=48.
The second triangle is also isosceles, so to find 2
we can use 180-42=138 (supplementary angles rule)
and given 10x-8=138
