a rectangular prism
a triangular pyramid
a rectangular pyramid
Answer:
A rectangular pyramid
Answer:
rectangular pyramid
Step-by-step explanation:
just took the test
The figure can be made using the net shown is a rectangular pyramid.
What is Difference between Pyramid and Prism?A three-dimensional shape is a pyramid. A pyramid's flat triangular faces unite at a common point known as the apex and have a polygonal base.
A prism is a polyhedron in geometry made up of an n-sided polygon basis, a second base that is a rigidly translated copy of the first base, and n additional faces that must all be parallelograms and connect the corresponding sides of the two bases.
Pyramids and prisms are both three-dimensional solids with flat faces and bases.
Yet, a pyramid only has one base, whereas a prism has two bases that are identical.
Here, the base is rectangular then the figure shows A rectangular pyramid.

You roll a pair of six-sided number cubes, numbered 1 through 6. What is the probability of rolling two odd numbers? (Enter your probability as a fraction
Answer:
1/4 or 25%
Step-by-step explanation:
The probability for rolling an odd number is 50% or [tex]\frac{1}{2}[/tex] because there are 3 odd numbers, (1, 3, 5) and 6 total outcomes (1, 2, 3, 4, 5, 6). [tex]\frac{3}{6} =\frac{1}{2}[/tex]
The probability for rolling two odd numbers in a row is
[tex]\frac{1}{2} *\frac{1}{2} =\frac{1}{4}[/tex]
So, the probability of rolling an odd number twice is 25% or [tex]\frac{1}{4}[/tex].

Find the length of the radius of the circle.
a. r = 3 d. r = 5
b. r = 4 e. r = 6
c. r = 4.5
Answer:
D) r=5
Step-by-step explanation:
Any triangle formed with one side of the triangle being the diameter of the circle it’s inscribed in will be a right triangle.
6²+8²=c²
36+64=c²
100=c²
√100=c
c=10
So the diameter is 10. That makes the radius 5.

Find 0% of 200:
Find 100% of 200:
Find 50% of 200:
Find 25% of 200:
Find 75% of 200:
Answer:
0
200
100
50
150
Step-by-step explanation:
0% of 200 = 0
100% of 200
= ( 100 / 100 ) x 200
= 1 x 200
= 200
50% of 200
= ( 100% of 200 ) / 2
= 200 / 2
= 100
25% of 200
= ( 50% of 200 ) / 2
= 100 / 2
= 50
75% of 200
= ( 75 / 100 ) x 200
= ( 75 x 200 ) / 100
= 75 x 2
= 150
What is the measure of each angle of a regular 26-gon?
Answer:
Angle of Regular polygon = 166.15° (Approx.)
Step-by-step explanation:
Given:
Regular polygon with 26 sides
Find:
Measure of each angle of Regular polygon
Computation:
Angle of Regular polygon = [(n-2)180] / n
where n = number of sides
Angle of Regular polygon = [(26-2)180] / 26
Angle of Regular polygon = [(24)180] / 26
Angle of Regular polygon = [4,320] / 26
Angle of Regular polygon = 166.15° (Approx.)

Given Angle 1 =xº and angle 2 = (x +50)°.
Find the value of x. Then find angle 1 and 2
Answer:
x=65
Angle 1=65
Angle 2=115
Step-by-step explanation:
We know that angle 1 + angle 2 = 180. Writing it in terms of x, we get x + (x + 50)= 180. Then you have 2x+50=180. Subtracting 50 from both sides gives you 2x=130. Dividing both sides by 2, you get x=65. Angle 1 is 65 degrees. 180-65=115.
4≤n−4. a little help?
Answer:
Just isolate the variable by performing inverse operations. Its like solving an equation but the sign is different.
Step-by-step explanation:
Well add 4 to both sides
8≤n
Thats basically it
Answer:
n ≥ 8
Step-by-step explanation:
We want to isolate n to solve the inequality. To do that, you add 4 to both sides, so 4 + 4 = 8 on the left and n - 4 + 4 = n on the right. That leaves you with 8 ≤ n, or n ≥ 8.

Find the midpoint between the following two points
(5, 10), (25, 8)
Answer:
(15,9)
Step-by-step explanation:
let [tex]x_{1}=5, x_{2}=25, y_{1}=10, y_{2}=8\\[/tex]
where the formula of the midpoint is ([tex]\frac{x_{1}+x_{2} }{2} ,\frac{y_{1}+y_{2} }{2}[/tex])
so, ((5+25)/2, (10+8)/2)
Thus, (15,9)
