Four numbers are written in a row. the average of the first two is 21, the average of the middle two is 26, and the average of the last two is 30. what is the average of the first and last of the numbers?
will give brainliest
(a) 24. (b) 25. (c) 26. (d) 27. (e) 28.
Using the 3 given means, we can see that the mean of the first and last digits is 25, so the correct option is b.
What is the average of the last two numbers?We have 4 numbers:
a, b, c, d.
We know that:
(a + b)/2 = 21(b + c)/2 = 26(c + d)/2 = 30And we want to get
(a + d)/2
We can write this as:
(a + b)/2 - (b + c)/2 + (c + d)/2 = 21 - 26 + 30 = 25
The correct option is b.

Answer:
D
Step-by-step explanation:
because 4 quarters is 100 and 3 quarters is 75 so 4 and 3 quarters is 7 quarters and that would give you 175 so if you add both 200 and 175 that gives you 375
A kite is made up of two isosceles triangles, KIT and KET, with the lengths shown. The top triangle of the kite, ΔKIT, is made from approximately 17 square inches of material. Isosceles triangles K I T and K E T are connected at side K T. The length of K T is 10 inches. The length of sides K E and E T are 8 inches. The lengths of sides K I and I T are 6 inches. Heron’s formula: Area = StartRoot s (s minus a) (s minus b) (s minus c) EndRoot How much material is used for the entire kite, quadrilateral KITE? Round to the nearest square inch. 31 square inches 34 square inches 48 square inches 62 square inches.
The material needed for the kite is the area of the kite
The amount of material needed for the entire kite is 48 square inches
How to determine the amount of materialThe given parameters:
KI =6 inches
ET = 8 inches
KT=10 inches
Area of ΔKIT = 17 square inches
Start by calculating the area of the bottom triangle using:
Area = 0.5 * Base * Height
So, we have:
Area = 0.5 * KI * KT
This gives
Area = 0.5 * 6 * 10
Area = 30
The amount of material used is then calculated as:
Material = Area of the bottom triangle + Area of ΔKIT
This gives
Material = 30 + 17
Material = 47
This is approximately 48
Hence, 48 square inches of material is used for the entire kite

Final Question: What is the measure of x?
Angles are not necessarily drawn to scale.
Answer:
[tex]x=114[/tex]
Step-by-step explanation:
Since we know that a straight line is 180°, and we know that one of the angles is 66°, we can write a simple equation to figure this out: [tex]x+66=180[/tex] Then, to solve the equation all you would need to do is subtract [tex]66[/tex] from both sides to get [tex]x=114[/tex].

Answer:
[tex]f^{-1}(x)=\sqrt{x+1}-3[/tex]
Step-by-step explanation:
We have the function:
[tex]f(x)=y=x^2+6x+8[/tex] with the domain restriction [tex]\{x\geq -3\}[/tex].
And we want to find the inverse of our function.
To find the inverse of our function, we take the following steps:
1) Swap x and y. 2) Solve for y.Therefore, our inverse will be:
[tex]x=y^2+6y+8[/tex]
First, let's subtract 8 from both sides. So:
[tex]x-8=y^2+6y[/tex]
To solve for y, we can complete the square. To complete the square, we:
1) Divide the coefficient of the b term by 2. 2) Square that. 3) Add that number to both sides.Our b term is 6. [tex]6/2=3[/tex], and [tex]3^2=9[/tex]. So, we will add 9 to both sides. This yields:
[tex](x-8)+9=(y^2+6y+9)[/tex]
Simplify the left. Complete the square on the right. So:
[tex]x+1=(y+3)^2[/tex]
Take the square root of both sides and solve for y:
[tex]y+3=\sqrt{x+1}\Rightarrow y=\sqrt{x+1}-3[/tex]
Subtract 3 from both sides. So, our inverse is:
[tex]f^{-1}(x)=\sqrt{x+1}-3[/tex]
Part 2)
See below for graph.
Here is also a good time to reinforce the idea of inverses. Notice that the domain of our original function f(x) is [tex]x\geq-3[/tex]. So, this means that the range of f(x) is (looking at the graph) is [tex]y\geq-1[/tex].
When we find the inverse, we will flip the domain and range. Therefore, the domain of our inverse function will be the range of our original function, and the range of our inverse function will be the domain of our original function.
From the graph, we can see that f⁻¹(x) has a domain of [tex]x\geq-1[/tex] and a range of [tex]y\geq -3[/tex]. Therefore, their domain and range are indeed opposites.
And we're done!

6 unit cubes and 18 smaller cubes of volume 1/27 cubic inches
=========================================================
Explanation:
Block A = unit cube that has side length of 1 inch
Block B = cube that has side length 1/3 inch
Block B has a volume of (1/3)*(1/3)*(1/3) = 1/27 cubic inches
If we have 180 of block B, then
180*(1/27) = 180/27 = 6.6667 approximately
The first 6 before the decimal point tells us we have 6 block A's. This is the same as saying that we have 6 cubic inches so far.
The 0.6667 at the end means we have 0.6667*27 = 18.0009 = 18 block B's
So we have 6 unit cubes (block A) and 18 smaller cubes (block B) that have a volume of 1/27 cubic inches
--------------
Another way to look at it
180/27 = (162+18)/27
180/27 = 162/27+18/27
180/27 = 6+18/27
180/27 = 6 remainder 18
The last line can also be found through using long division.
The 6 refers to 6 unit cubes and the remainder 18 is the left over 18 smaller blocks.

Answer:
You would at least a 90 to average out your score to an 84
but I dont know how to get the inequality sorry
I hoped this helped a little
Step-by-step explanation:
Fisrt you will need to find the average of the numbers by adding them up and dividing by 3 ( because there are 3 numbers )
which would give you 81
then you have to get at least above an 81 to make it go higher but you may have to do a little more than that there for 90 is what you need

Can the sides of a triangle have lengths 7.6, 2.5, and 2.2?
Answer:
No.
Step-by-step explanation:
Given the following question:
[tex]7.6, 2.5, 2.2[/tex]
In order for any given sides to form a triangle it has to pass the triangle inequality theorem, which is the sum of any two given sides of the triangle has to be greater than the third side in order for it to be a triangle.
In this case...
[tex]7.6, 2.5, 2.2[/tex]
[tex]7.6 + 2.5 = 10.1[/tex]
[tex]10.1 > 2.2[/tex]
[tex]2.5+2.2=4.7[/tex]
[tex]4.7 < 7.6[/tex]
[tex]7.6 +2.2=9.8[/tex]
[tex]9.8 > 7.8[/tex]
Therefore, your answer is "no" the following sides do not form a triangle.

3(2x+1)+7=6x-3-2(2-4x)
What is x?
Give as an improper fraction in its simplest form
Answer:
Step-by-step explanation:
Use distributive property:a*(b +c) = (a*b) + (a*c)
3(2x + 1) + 7 = 6x - 3 - 2(2-4x)
3*2x + 3*1 +7 = 6x - 3x -2*2 + (-2)*(-4x)
6x + 3 + 7 = 6x - 3 - 4 + 8x
6x + 10 = 14x - 7
6x - 14x = - 7 - 10
-8x = -17
x = -17/-8
x = 17/8
