The length of line segment AD is 6.8 cm. The length of line segment AB is 3 cm. The length of line segment BC is 1.6 cm. Find the length of line segment CD.
Answer:
9.6
Step-by-step explanation:
This is a four side figure which is most likely to be a trapezium.So AD is the hypotenuse,AB is side (a),BC is the height and CD is side (b).

A sphere has a radius of 4.5 cm. What is the volume of the sphere? Round your final answer to the nearest hundredth.
The equation for the Volume of a Sphere is:
V = [tex]\frac{4}{3}[/tex]πr²
V= volumer = radiusYou have been given the radius of 4.5 cm, so all you have to do is plug this information into the equation and solve!
V = [tex]\frac{4}{3}[/tex]π(4.5)²
↓
V = [tex]\frac{4}{3}[/tex]π × 20.25 or V= [tex]\frac{4}{3}[/tex] × 20.25π
↓
V= 27π (plug this into your calculator to get your numerical value)
V≈ 84.82
A circular field has a diameter of 50 yards. If a fence needs to be built to go around the field, how many yards of fencing are needed?
157 yards
314 yards
100 yards
1962 yards
Answer:
A.
Step-by-step explanation:
A fence is needed for the circular field.
Circumference is basically perimeter but for circles.
Knowing this information, we can use the formula for circumference.
C = [tex]\pi[/tex]d
C = (3.14)(50)
C = 157

what is 16.2 simplified (and 121 simplified to)
Answer:
16.2 = [tex]\frac{81}{5}[/tex] and 121 = [tex]\frac{121}{1}[/tex]
Step-by-step explanation:
16.2 can be simplified to its fraction form, which is [tex]\frac{81}{5}[/tex]
[tex]16+\frac{2}{10} =\frac{81}{5}[/tex] which is 16.2121 is already simplified since it is a whole number, but its fraction form would be [tex]\frac{121}{1}[/tex]
[tex]121+\frac{0}{10} =121[/tex] which is 121-----

Nine years ago, Katie was twice as old as Elena was then.
Elena realizes, "In four years, I'll be as old as Katie is now!"
Elena writes these equations to help her make sense of the situation:
[tex]k-9=2(e-9)\\e+4=k[/tex]
If Elena is currently years old and Katie is years old, how old is Katie now?
Answer:
Given that Elena is currently e years old and Katie is k years old. Now, nine years ago, Katie was twice as old as Elena was.
So, k - 9 = 2(e - 9)
⇒ k - 2e + 9 = 0 .............. (1)
And, in four years, Elena will be as old as Katie is now.
So, k = e + 4
⇒ k - e - 4 = 0 ............... (2)
Therefore, the equations (1) and (2) matches the conditions. (Answer)

The volume of this cone is 1,017.36 cubic inches. The radius is 9 inches. What is the height of this cone?
Answer:
Step-by-step explanation:
The radius of cone = 9 cm
Step-by-step explanation:
Formula : Volume of a cone = , where r= radius , h= height of the cone.
Given: Volume = 1,017.36 cubic centimeters
h = 12 centimeters
Substitute these values in formula , we get

Step-by-step explanation:
It is asking for 3 numbers greater than 0.39, with three in the tenth place (0.x000) that is less than 1. By adding a number in the thousandth place to 0.39, we automatically make it larger. Adding more digits will make it slightly larger, as long as it isn't a 0. All 4 answers I have provided are correct, however, I would just use the first 3 for your question.

Answer:
Radius= 8.99 mm (9 mm)
Step-by-step explanation:
We use the formula for the volume of a cone which is
1/3 pi ×(radius)^2 *height
932.58 = (pi) × (11) ×(r^2/3)
Radius^2 = (932.58×3) / (11pi)
= 80.96m
Radius= 8.99mm
Answer:
volume= 1/3πr²h
932.58=1/3×3.14×r²×11
3×932.58=34.54×r² ×3
3
2,797.74 = 34.54×r²
34.54. 34.54
√r²= √81

Classify the pair of angles, then find the value of x.
(PLEASE HELP ME OUT!!)
Answer:
X = 55°
Step-by-step explanation:
You can tell if a pair of angles, in this case, is 90° if you see the red box in the corner of the angle.
The pair of angles in the picture are complementary angles, which add up to 90°. Therefore, subtract 35 from 90 to find the value of X which is 55°.

x = 5 makes 2x≤ 10 true but not 2x < 10 because "≤" means less than or equal to, which means 2x would be the same as 10, so 10 ÷ 2 = 5, x = 5.
Answer:
Step-by-step explanation:
2x ≤ 10, when x = 5
2(5) ≤ 10
10 ≤ 10 (10 is less than OR equal to 10)
2x < 10, when x = 5
2(5) < 10
10 < 10 (10 is less than 10) - that is false
x = 5 does not makes 2x < 10 true because 10 can't be less than 10.

Answer:
A: 1.5
B: A = n/1.5
C: This means every bowl you make, you would need 1.5 pounds of clay.
Step-by-step explanation:
A: The constant of proportionality is otherwise known as the slope. The formula for the slope is [tex]y_{2}[/tex]-[tex]y_{1}[/tex] / [tex]x_{2}[/tex]-[tex]x_{1}[/tex] (rise over run.) Lets plug the values in.
4.5-0 = 4.5
3-0 = 3
4.5/3 =1.5
B:
A = n/1.5
C:
The point (1,1.5) is representing the x value, the number of bowls, and the y value, the amount of clay in pounds.
This means every bowl you make, you would need 1.5 pounds of clay.
A net of a square pyramid is shown below. 5.95 cm 5.1 cm What is the surface area, in square centimeters, of the pyramid.
Answer:
86.7
Step-by-step explanation:
L x W = 5.1 x 5.1 = 26.01
B x H ÷ 2 = 5.1 x 5.95÷2 = 15.1725
15.1725 x 4 = 60.69
60.69 + 26.01 = 86.7
The surface area of the square pyramid is 92 square centimeters.
The given figure is a square pyramid.
We have to find the surface area.
Surface area = a² + 2a√(a²/4 + h²)
a is 5.1 cm and h is height which is 5.95 cm.
Surface area = 5.1² + 2(5.1)√(5.1²/4 + 5.95²)
=26.01 + 10.2 √(26.01 /4 +35.4025)
=26.01+10.2 √6.5025+35.4025
=26.01+10.2√41.905
=92 square centimeters.
