Answer:
Triangular prism
Step-by-step explanation:
Got it right on edge 2022 :)
The three-dimensional figure that has exactly three rectangular faces is a rectangular pyramid
What is the volume of a pyramid?The volume of a pyramid, is the product of the area of its base with the height of the pyramid, and divide by 3. We express this product with the formula V = ( 1/3) ×B×h, where B is the area of the base of the pyramid, and h is its height.
Volume of Pyramid = ( 1/3 )a²H
Given data ,
Let the pyramid be represented as A
Now , A rectangular prism has 6 faces, where each face is a rectangle.
A rectangular pyramid has 5 faces, where 4 faces are triangles and 1 face is a rectangle.
A triangular prism has 5 faces, where 2 faces are triangles and 3 faces are rectangles.
A triangular pyramid has 4 faces, where 3 faces are triangles and 1 face is a rectangle.

Answer:
813 N/m²
Step-by-step explanation:
The units of pressure tell you it is found by dividing force by area. Here, we need to convert the units of the given area so we can express the pressure appropriately.

pressure = force / area
pressure = (61 N)/(750 cm² × ((1 m)/(100 cm))²) = (61 N)/(0.0750 m²)

Answer:
P(vanilla cupcake)= 1/2
Step-by-step explanation:
Knowing that:
3 vanilla cupcakes
3 other cupcakes
Total = 6
To Find:
What is the experimental probability that the next cupcake sold will be a vanilla cupcake?
Write your answer as a fraction or whole number.
P(vanilla cupcake)=
Solve:
Experimental probability is expressed as:
(Favorable outcomes) / (Total outcomes)
The favorable outcome in this situation is vanilla cupcakes. There were 3 vanilla cupcake sold, so this is the numerator of our fraction.
To find the total outcomes we add 3 + 3, which equals 6. This will be the denominator of our fraction.
The fraction used to express experimental probability will be: 3/6
We can further simplify this to 1/2.
Thus:
P(vanilla cupcake)= 1/2 or 3/6

If f(x) = -2x^2 + x - 5, what is f(3)?
Answers
Answer:
f(3) = -10Step-by-step explanation:
Given
f(x) = -2x² + x - 5Solving
To find f(3), substitute x = 3 in the function⇒ f(3) = -2(3)² + (3) + 5⇒ f(3) = -2(9) + 8⇒ f(3) = -18 + 8⇒ f(3) = -10Answer:
f(3) = 6

f(x)=2x^2 + x -5
f(3) = 2 (3)^2 + (3) - 5
f(3) = 8 + 3 - 5
f(3) = 11-5

The number of calories C varies directly as the number of ounces N of avocado that is consumed by the body and C is 380 calories N is 20 ounces. Find C when N is 36 ounces.
Answers
Given that C varies directly as N, the value of Calories C when the number of ounces N is increased to the given value is 684 calories.
What is Proportional relationships?
Proportional relationships are relationships between two variables where their ratios are equivalent.
Direct variation equation is a linear equation in two variables.
It is expressed as;
a ∝ b then a = kb
Where k is the proportionality constant.
Given the data in the question;
Calories C = 380 caloriesNumber of ounces N = 20 ouncesSince Calories C and Number of ounces N varies directly, we find their proportionality constant.
a ∝ b then a = kb
C = kN
380 calories = k × 20 ounces
k = 380 calories / 20 ounces
k = 19 calories/ounces
Now,we find C when N is 36 ounces.
C = kN
C = 19 calories/ounces × 36 ounces
C = 684 calories
Given that C varies directly as N, the value of Calories C when the number of ounces N is increased to the given value is 684 calories.

The value of y is directly proportional to the value of x. If y=2/3 whenx=1/12 , what is the value of y when x = 1/2 ?
Answers
Step-by-step explanation:
Y is directly proportional to X" can be rewritten as a mathematical expression of the form Y = KX
"K" is the constant of proportionality and must be determined from the initial information.
If Y = 2/3 when X=1/12means 2/3=1/12
K = 2/3÷1/12 = 8
Now that we know the value of K, we can use it to calculate the value of Y when X=1/2
Y = (8)(1/2) = 8/2=4
Y=4
