Using a system of equations, the solution matrix that gives the weight of a fizgig and the weight of a whatsit is:
[x y] = [5 4]
What is a system of equations?A system of equations is when two or more variables are related, and equations are built to find the values of each variable.
For this problem, the variables are given as follows:
Variable x: weight of a fizgig.Variable y: weight of a whatsit.Two fizgigs and three whatsits weigh 22 noozwhats, henec:
2x + 3y = 22.
Four fizgigs and two whatsits weigh 28 noozwhats, hence:
4x + 2y = 28.
Simplifying by 2:
2x + y = 14
y = 14 - 2x.
Replacing in the first equation:
2x + 3(14 - 2x) = 22
2x + 42 - 6x = 22
4x = 20
x = 20/4
x = 5 noozwhats.
y = 14 - 2(5) = 4 noozwhats.
Hence the solution matrix that gives the weight of a fizgig and the weight of a whatsit is:
[x y] = [5 4]

10 over h equals 52 over 13. Represent for h.
a number between 10 and 100 there are 5 base ten blocks and the tens is greater than the number of ones blocks one of the digits is 4
Please explain how to find answer so i can teach my child. Thought it was 54 but that is incorrect
The number between 10 and 100 which has 5 base ten blocks and one of the digits is 4 will be 41.
Let the two digits be x and y
There are 5 base ten blocks therefore the sum of the numbers will be 5
i.e. x + y = 5 ..eq-1
One of the digit is 4
So, let the value of x = 4
Putting the value of x in eq-1
4 + y = 5
y = 5 - 4
y = 1
Since tens placed number block is a greater than the ones block,
y > x
4 > 1
therefore 4 will be at tens place and 1 will be kept at ones place and number so formed will be 41.

Write the equation of the line that passes through the points (1,1) and (11,−2).
The equation of the line in slope-intercept form is: y = -3/10x + 13/10.
How to Write the Equation of the Line?Given the points, (1,1) and (11,−2). Follow the steps explained below.
Step 1: Find the slope of the line:
Slope (m) = change in y / change in x = (-2 - 1)/(11 - 1)
Slope (m) = -3/10
Step 2: Substitute m = -3/10 and (a, b) = (1, 1) into y = mx + b to find the value of b
1 = -3/10(1) + b
1 = -3/10 + b
1 + 3/10 = b
b = 13/10
Step 3: Substitute m = -3/10 and b = 13/10 into y = mx + b
y = -3/10x + 13/10
Thus, the equation of the line in slope-intercept form is: y = -3/10x + 13/10.

Calcula la altura de un cono si el diámetro mide 30 cm y su generatriz 17 cm .
La altura del cono es de 8 centimetros.
¿Como encotrar la altura del cono?Sabemos que para un cono de radio R, altura H, y generatriz G se cumple la relación:
R^2 + H^2 = G^2
Resolviendo para la altura obtenemos:
H = √(G^2 - R^2)
En este caso sabemos que le diámetro es de 30 cm, entonces el radio será de:
R = 30cm/2 = 15cm
Y la generatriz es de 17cm, entonces G = 17cm
Reemplazando eso en la ecuación para la altura obtendremos:
H = √((17cm)^2 - (15cm)^2) = 8cm

How can graph theory be used to evaluate the given graph?The given parameters are;
H = A connected graph
Number of edges in the spanning tree of H = 21
First part
Required:
The number of vertices in the spanning tree of H
Solution;
In graph theory, a spanning tree is one that contains all the vertices of the graph.
The number of edges in a tree that has n vertices is 'n - 1'
Therefore;
Number of edges = n - 1 = 21
n = 21 + 1 = 22

Step-by-step explanation:
Let's solve the problem,

→ -4 × 2 = 8x - 6
→ -8 = 8x - 6
→ 8x = -8 + 6
→ x = -2/8
→ [ x = -0.25 ]
Thus, solution is -0.25.
Can anyone explain this?
Answer:
0.250
Step-by-step explanation:
Given from the question, we know that the summation (adding all values together) of all P(x) values is equal to 1.
And, we do know that P(2) = P(4).
This means , we will subtract all the known P(x) values from 1 to get the value of P(2) + P(4).
P(2) + P(4) = 1 - 0.0425 - 0.3750 - 0.0625 - 0.0200 = 0.500
Since P(2) = P(4), we divide 0.500 by 2 to get the value of P(2) and P(4).
P(2) = P(4) = 0.500 ÷ 2 = 0.250

a baseball is tossed up into the air at an initial velocity 16 m/s. The
height of the baseball at time t in seconds is given by h(t) = 16t - 4.9t² (in meters).
Answer: Average velocity = 11.1 m/s
Step-by-step explanation:
Given data,
A baseball is tossed up into the air at an initial velocity = 16 m/s.
The height of the baseball at time t in seconds is given by,
h(t) = 16t - 4.9t² (in meters).
So,
The average velocity is,
To calculate the velocity travelled by the ball, differentiate the function.
dh/dt = 16 - 2(4.9t)
dh/dt = 16 - 9.8t (eq-1)
Let us assume, t = [1,1.5]
Substitute t for 1 in the above Differential function
dh/dt = 16 - 9.8 (1)
But ,
dh/dt = velocity
So, dh/dt = V
V = 16 - 9.8
V = 6.2 m/s
Therefore,
Average velocity = ( U + V ) / 2
Average velocity = (16 + 6.2)/2
Average velocity = 22.2/2
Average velocity = 11.1 m/s
Hence, Average velocity = 11.1 m/s.

Answer:
The domain of this function is (in order of least to greatest) is [-2,-1,0,3.5,4,5.5, and 8]
The range of this function is (in order from greatest to least) is [6,5.5,4,0,-1, and -3.5]
Step-by-step explanation:
To find the domain you need to look at all of you input or x values so the question is asking to name the values of x for your domain. You look at the table to where x is and name the numbers listed in this case it's [-2,-1,0,3.5,4,5.5, and 7]
To find the range you need to look at the listed outputs or y values. You are essentially doing the same steps but instead you looking at y for the listed values. Generally when it comes to domains that have the same range (for example (4,-1) and (5.5,-1)) you would only write it once in the list of ranges so like [6,5.5,4,0,-1, and -3.5]
