For the first one we just need to find the compliment of the union (.98) which is .02
Union formula:
A∪B=A+B-A∩B
We will let T= text and D= diagram
we know that
.98=.88+.32-T∩D
Solve and find that T∩D= .22
Only diagram: .32-.22= .1
Only text: .88-.22= .66
Text and diagrams is the intersection we found earlier or .22

Find the circumference.
Use 3.14 for it.
r = 5 cm
C = [?] cm
C= Ttd
Answer:
C=2(3.14)×(5)
C=31.4cm
The circumference of circle is 31.4 cm
What is circumference of circle?"It is the distance around the perimeter of a circle."
Formula for circumference of circle:"C = 2 × π × r,
where r is the radius of the circle."
For given question,
We have been given the radius of a circle.
r = 5 cm
We need to find the circumference of circle.
Using the formula for circumference of circle,
⇒ C = 2 × π × r
We need to use π = 3.14
⇒ C = 2 × 3.14 × 5
⇒ C = 2 × 5 × 3.14 ...............(since a × (b × c) = (a × b) × c)
⇒ C = 10 × 3.14
⇒ C = 31.4 cm
This means, the circumference of circle having radius r = 5 cm
is C = 31.4 cm
Therefore, the circumference of circle is 31.4 cm

Find the surface area of a square pyramid with side length 2 mi and slant height 5 mi.
5 mi
2 mi
2 mi
Answer: 24 in2
Step-by-step explanation:
The square pyramid has a surface area of 24 square miles.
What is the Surface area?The area or region that an object’s surface occupies is known as its surface area. Volume, on the other hand, refers to how much room an object has. There are numerous shapes and dimensions in geometry, including spheres, cubes, cuboids, cones, cylinders, etc. Each form has its own volume and surface area.
The surface area of a square pyramid is given by the formula:
[tex]S = L^2 + 2L\sqrt{((L/2)^2 + H^2)[/tex]
where L is the length of the base, H is the height of the pyramid, and S is the surface area.
Given L = 2 mi and slant height = 5 mi, we need to find H.
Using the Pythagorean theorem, we can find H as follows:
[tex]H^2 = (slant\ height)^2 - (1/2 L)^2\\\\H^2 = 25 - 1\\\\\H^2 = 24\\\\H = \sqrt{24[/tex]
Now, we can plug in the values of L and H into the formula for surface area:
[tex]S = L^2 + 2L\sqrt{((L/2)^2 + H^2)} \\\\S = 2^2 + 2(2)\sqrt{((2/2)^2 + (\sqrt{24})^2)}\\\\S = 4 + 4\sqrt{(1 + 24)}\\\\S = 4 + 4\sqrt{25}\\\\S = 4 + 4(5)\\\\S = 24[/tex]
Therefore, the surface area of the square pyramid is 24 square miles.

volume=15×5×5+8×4×5+8×4×5
=375+160+160
=695 m³
Answer:
695 m^3
Step-by-step explanation:
With this object, there are three rectangular prisms. The equation to find the volume of them is L*W*H.
So, with the small one in the front, the sides are 8, 4, and 5, so do:
8*4*5 ---> 160
Next, with long middle one, the sides are 5, 5, and 15, so do:
5*5*15 --->375
Then, with small one in the back, 8, 4, and 5 again, so do:
8*4*5 ---> 160
To finish it off, add them all together.
160 + 375 + 160 = 695 m^3

Find the missing angle measures. This is 8th grade math btw
Answer:
w is 146
x is 90
y is 34
z is 56
Answer:
w = 146 degrees
x = 90 degrees
y = 34 degrees
z = 56 degrees
Step-by-step explanation:
Right angles will always add up to 90 degrees.
Straight lines will always add up to 180 degrees.
Since x is a right angle, x = 90 degrees.
Since z + 34 = 90 degrees (a right angle):
90 - 34 = z
90 - 34 = 56 degrees
Since x + y + z = 180 degrees (a straight line), simply plug in the numbers we have found already:
90 + y + 56 = 180
y = 180 - 90 - 56
y = 34
Since w + 34 = 180 degrees (a straight line):
180 - 34 = w
180 - 34 = 146 degrees

EVE ELEVE
LE
EL
Answer:
Flashlight ; = $2.99
Water bottle = $1.50
Toothbrush = $1.29
Compass = $3.29
Step-by-step explanation:
Sales tax = 7%
Item: _____ price
Flashlight ; = $3.20
Water bottle = $1.61
Toothbrush = $1.38
Compass = $3.52
Total cost = price of item + sales tax
Sales tax = 7%
Total cost = (1 + 7%) * price of item
Total cost = (1 + 0.07) * price of item.
Total cost = 1.07* price
Flashlight = 1.07*1.29 = $3.20
Water bottle = 1.07*1.50 = $1.61
Toothbrush = 1.07*1.29 = $1.38
Compass = 1.07*3.29 = $3.52

Brenna is constructing a circle inscribed in a triangle. She has partially completed the construction, as shown below. What should be her next step in the construction?
Connect vertex B to the arc marking to complete the angle bisector
Find the angle bisectors for angles A and B
Connect three arc markings together to form the triangle
Use the incenter to determine the center to construct the circle
The construction is missing, so i have attached it.
Answer:
Use the incenter to determine the center to construct the circle.
Step-by-step explanation:
From the attached image, we can see that the 3 bisector of the three interior angles in the triangle intersect at a point. This point is known as the incentre of the triangle.
Now, to draw an inscribed circle inside the triangle, we will draw a perpendicular line from the incentre to any of the 3 sides and we will use the incentre as centre to draw the circle to touch each of the 3 perpendicular points.

Answer:
The area of the circle is equal to [tex]9\pi[/tex].
Step-by-step explanation:
Given that,
The area of sector is, [tex]\dfrac{17}{2}\pi[/tex]
The central angle is [tex]\dfrac{17}{9}\pi[/tex]
We need to find the area of circle.
We know that,
[tex]\text{Area of sector}=\dfrac{\text{central angle}}{2\pi}\times \text{Area of circle}\\\\\text{Area of circle}=\dfrac{2\pi \times \text{Area of sector}}{\text{central angle}}\\\\=\dfrac{2\pi \times \dfrac{17\pi}{2}}{\dfrac{17\pi }{9}}\\\\=9\pi[/tex]
So, the area of the circle is equal to [tex]9\pi[/tex].
