To find the area of the composite figure, we need to calculate the areas of the individual shapes and then sum them up.
Let's start with the triangle:
The base of the triangle is given as 6 feet, and the height is given as 3 feet. The formula for the area of a triangle is A = (1/2) * base * height. Plugging in the values, we get:
= 9 ft²
Next, let's calculate the area of the square:
The side length of the square is given as 2 feet. The formula for the area of a square is A = side length * side length. Plugging in the value, we have:
= 4 ft²
Now, let's find the area of the semicircle:
The diameter of the semicircle is also given as 6 feet, which means the radius is half of that, so r = 6 ft / 2 = 3 ft. The formula for the area of a semicircle is A = (1/2) * π * r². Plugging in the value, we get:
= (1/2) * 3.14 * 3 ft * 3 ft
≈ 14.13 ft²
To find the total area of the composite figure, we add the areas of the individual shapes:
= 9 ft² + 4 ft² + 14.13 ft²
≈ 27.13 ft²
Therefore, the approximate area of the composite figure is 27.13 square feet.

Step-by-step explanation:
The min. is just the lowest number. The lower quartile is the number in the middle of the numbers below 42, the median is the number in the very middle, the upper quartile is the middle number above 41 and the interquartile is the upper quartile minus the lower quartile.
Given A(2, 3) B(1, 4) C(1, 3) D(-2, 2). How are AB and CD related?
The vector AB is not related with the vector CD as k is not the same for each pair of components.
Are two vectors similar?In this question we must prove if the vector AB is a multiple of the vector CD, that is:
[tex]\overrightarrow{AB} = k \cdot \overrightarrow {CD}[/tex]
[tex]\vec B - \vec A = k \cdot [\vec D - \vec C][/tex]
(1, 4) - (2, 3) = k · [(- 2, 2) - (1, 3)]
(- 1, 1) = k · (- 3, - 1)
Hence, the vector AB is not related with the vector CD as k is not the same for each pair of components.

4z-10=10 what do i solve for z
Answer:
z = 5
Step-by-step explanation:
To solve for z, means to get z all by itself on one side of the equation. In your equation z has had two things done to it. First, z has been times by 4, then 10 is subtracted. So, you "un-do" that in reverse order.
FIRST, add 10. To reverse or "un-do" subtracting.
4z - 10 = 10
4z -10+10 = 10+10
4z = 20
Then, divide by 4 to reverse the multiplying.
4z/4 = 20/4
z = 5
see image.
Also, you can check you answer.
put in 5 in place of z and be sure that you get a true statement.
4(5) - 10 = 10
20 - 10 = 10
10 = 10 Checked!
Answer:
[tex]z=5[/tex]
Step-by-step explanation:
First, substitute in 5 for z: [tex]4(5) -10=10[/tex]
Since [tex]4*5=20[/tex], we can now simplify the equation to [tex]20-10=10[/tex].
Now, check the equation to make sure that the value of z is correct. Do this by subtracting [tex]20-10[/tex] to see if it results in a solution of 10.
Since the equation [tex]20-10=10[/tex] is equal/true, we can conclude that [tex]z=5[/tex].

Suppose that a rectangular piece of glass has a perimeter of 20 meters. if we multiply both its length and its width by 4, what will be the perimeter of the new rectangular piece of glass?
The perimeter of the new rectangular piece of glass is 80m.
What is the perimeter of a rectangle?The sum of all sides of a rectangle is the perimeter of the rectangle.A rectangle has two equal lengths and two equal widths.Therefore, the perimeter 'P' of a rectangle is the sum of two equal lengths and two equal widths. That is, 'P=2l+2w' where 'l' is the length and 'w' is the width of the rectangle.
Here, a rectangular piece of glass has a perimeter of 20 meters.
As we know the perimeter P of a rectangle is given by the formula,
P = 2l+2w...(1)
Therefore,
20 = 2l + 2w
20 = 2(l + w)
20/2 = l + w
10 = l + w ....(2)
Now, both the length and width of the rectangle are multiplied by 4,
That is,
The new length of the rectangle is, l = 4l
The new width of the rectangle is, w = 4w
Therefore by substituting this in the equation(1) we get,
P = 2(4l) + 2(4w)
P = 8l + 8w
P = 8(l+w)....(3)
Substitute equation (2) in (3),
That is,
P = 8*10
P = 80m

The ages of all employees at a small convenience store are 36, 32, 38, and 28. What is standard deviation of ages for this population
The standard deviation is approximately 3.84
Step 1: Find the mean
Find the sum of the values, and divide by number of terms.
Mean (average) = (36+32+38+28)/4 = 134/4 = 33.5
We must use Standard Deviation formula which is attached as an image below.
X is the mean here, so lets plug in 33.5
Step 2. Distance from the mean squared |x-mean∣²
For each data point, we will plug in the numbers.
|36-33.5|²=2.5²=6.25
|32-33.5|²=1.5²=2.25
|38-33.5|²=4.5²=20.25
|28-33.5|²=5.5²=30.25
Step 3: Find the sum (∑)
We find the sum here by adding all the distances from the mean squared
∑|x-mean|²=59
Step 4: Divide the sum by the amount of points, 4
59/4=14.75
Step 5: Take the square root of step 4
[tex]\sqrt{14.75}[/tex] is about 3.84

Calculate the magnitude of the resultant vector:Resultant vector: vector that gives the combined effect of all the vectors. When we add two or more vectors, the outcome is the resultant vector.
For example,
Sum of vector (3,4) and vector (5,7)(3,4) + (5,7) = (3+5,4+7) = (8,11)
(8,11) is the resultant vector of vector (3,4) and vector (5,7)
Magnitude of a vector: the length of the vector. The magnitude of the vector a is denoted as ∥a∥.
Magnitude of a = (a₁, a₂)
∥a∥=[tex]\sqrt{a_{1}^{2} +a_{2}^{2} }[/tex]
In the given question,
v (8,10) and w (7, -1)
Adding the vectors,

Answer:
The translation rule is: (x,y) → (x-3, y+3)
Step-by-step explanation:
A translation rule in geometry is basically asking you what was done to move the shape to its new location on a graph.
In this particular problem, visualizing the graph isn't actually necessary. You only need to figure out what was added or subtracted to get the new numbers from the old ones.
In the beginning, point D was at the x coordinate 1. To make 1 into -2, you subtract three. The points E and F were also changed from their old numbers to the new ones by subtracting 3.
So, we know that the first half of our rule is x-3.
In the beginning, point D was at the y coordinate 3, but it changed to a 6. To get from 3 to 6, you add three more. Points E and F can also be made into their new numbers by adding 3.
So, we know that the second half of the rule is y+3.

Answer:
x = 2
Step-by-step explanation:
Simplifying expressions:5x - 7 - 5(7x - 12) + 7 = 0
Distribute (-5) to each term of (7x - 12)
5x - 7 + 7x*(-5) + (-12)*(-5) + 7 = 0
5x - 7 - 35x + 60 + 7 = 0
5x - 35x - 7 + 60 +7 = 0
Combine like terms.
-30x + 60 = 0
Subtract 60 from both sides
-30x = -60
Divide both sides by (-30)
x = (-60)/(-30)
x = 2
Answer:

Simplifying the Algebraic Equation.
( 5x - 7 ) -5 (7x - 12 ) + 7 = 0
Removing brackets.
5x - 7 - 35x + 60 + 7 = 0
Combining like terms.
5x - 35x + 60 + 7 - 7 = 0

A 10-foot board is to be cut into 3 pieces. Two of the pieces will be the same length and one piece will be 2 feet longer
than the other two.
Which equation could be used to solve for the lengths?
x+x+x=10+2
x+x+ 2 x= 10
x+x+x+2=10
x+x+x-2=10
Answer:
the third : x + x + x + 2 = 10
Step-by-step explanation:
x = the length of the first 2 pieces.
the third piece will be x+2 ft long.
so, the total length of the original board is the sum of all 3 pieces and must be all in all 10 ft.
10 = x + x + (x + 2) = x + x + x + 2
