the volume of this right trapezoidal prism is 380.25ft^3. what is the height ,x, of the prism? 5, 5, 8, 5.8, x.
Answer:
Hence, the height of the trapezoidal base is 7.2 ft.
Step-by-step explanation:
The height of the trapezoidal base is 7.2 ft.
Step-by-step explanation:
Consider the provided information.
The volume of trapezoidal prism is the area of the cross-section × the length.
Where B is the area of base, H is the length and V is the volume.
The length of the prism is 25.2ft and volume is 1279.152
Hence, the base area is 50.76 ft².
The base is trapezoid.
The area of trapezoid is
Substitute B=50.76, in above formula.
Hence, the height of the trapezoidal base is 7.2 ft.

In a company, there are 28 total employees. All employees who have worked there for more
than five years receive a gift.
If eleven employees have received the gift, what is the probability that a randomly
selected employee has received the 5-year gift?
The probability that a randomly selected employee has received the 5-year gift is 39.29%
What is the probability?Probability determines the chances that an event would happen. The probability the event occurs is 1 and the probability that the event does not occur is 0.
The probability that a randomly selected employee has received the 5-year gift = number of employees who have received the gift / total number of employees
11/28 x 100 = 39.29%

The lateral surface area of cone A is exactly 1/2
the lateral surface area of
cylinder B.
true or false?
The lateral surface area of cone A is exactly 1/2 the lateral surface area of cylinder B is option (A) true.
What is lateral surface area?The lateral surface area of a figure is the area of the non-base faces only. The lateral surface of an object is all of the sides of the object, excluding its base and top.
For the given situation,
The diagram shows the cone A and the cylinder B.
Cone A has the radius r and the slant height as h.
Cylinder B has the radius r and the height as h.
The lateral surface area of cone is [tex]\pi rh[/tex]
The lateral surface area of cylinder is [tex]2\pi rh[/tex]
1/2 × lateral surface area of cylinder B,
⇒ [tex]\frac{1}{2} (2\pi rh)[/tex]
⇒ [tex]\pi rh[/tex] = lateral surface area of cone A.
Hence we can conclude that the lateral surface area of cone A is exactly 1/2 the lateral surface area of cylinder B is option (A) true.

If you roll a fair 6-sided die and then flip a fair coin, what is the probability that you roll greater than 1 and get heads with the coin?
Answer:
5/12
Step-by-step explanation:
The odds for the die are 5 positive out of 6 possible outcomes
-- 2,3,4,5,6 are the positive outcomes - the ones you want - but there are a total of 6 outcomes or ways the die could land
The odds for the coin are 1 positive outcome out of 2 possible outcomes (heads or tails)
Once you have 5/6 for the die and 1/2 for the coin, you multiply them together.

A translation of 6,-6 followed by a rotation of 180 degrees
An irregular plane figure drawn on graph paper is framed 15 by 40 rectangle.To find its area,10,000 random points are generated,and 5,710 of them land inside the irregular region what is the area of the irregular region to the nearest integer
=========================================================
Explanation:
A = number of points that land inside the irregular figureB = number of randomly generated points totalIn this case,
A = 5,710B = 10,000Divide A/B to find the experimental probability of landing inside the figure
A/B = (5,710)/(10,000) = 0.571
There's about a 57.1% chance of landing inside the figure.
The entire region is 15 units by 40 units, giving an overall area of 15*40 = 600 square units.
Roughly 57.1% of this total area would be taken up by the irregular figure
57.1% of 600 = 0.571*600 = 342.6 which rounds to 343
The area of the irregular region is about 343 square units

Answer:
x = 15 , y = 15√(2)
Step-by-step explanation:
The triangle is isosceles where two angles are the same which mean two sides are also the same.
x = 15°
Pythagorean Theorem: a^2 + b^2 = c^2
15^2 + x^2 = y^2
15^2 + 15^2 = y^2
225 + 225 = y^2
450 = y^2
y = √(450) = 15√(2)
Answer:
x=15 and y=15root2
Step-by-step explanation:
tan45=p/b
1=x/15
x=15
again for right angle trangle
h=root (p+b)

The length of a rectangle is equal to triple the width. Write a system of equations can be used to tind the dimensions of the rectangle if the perimeter is 98 centimeters?
Answer:
98 = 2w + 2L,
L = 3w
Step-by-step explanation:
Use the perimeter formula:
2) Perimeter = 2w + 2L (where w is the width and L is the length)
Since the length is three times the width we can write:
L = 3w
We can substitue L with 3w:
Perimeter is equal to 98 so,
98 = 2w + 6w = 8w
W = 98/8
Therefore w is 12.25, and L is 36.75

Find the average rate of change of each function on the interval specified.
i only need #5 thank you :)
The average rate of change (AROC) of a function f(x) on an interval [a, b] is equal to the slope of the secant line to the graph of f(x) that passes through (a, f(a)) and (b, f(b)), a.k.a. the difference quotient given by
[tex]f_{\mathrm{AROC}[a,b]} = \dfrac{f(b)-f(a)}{b-a}[/tex]
So for f(x) = x² on [1, 5], the AROC of f is

Answer:
2. The change in expected height for every one additional centimeter of femur length.
Step-by-step explanation:
1. The expected height for someone with a femur length of 65 centimeters.
Doesn't make sense, that would be height value when centimeters = 65.
2. The change in expected height for every one additional centimeter of femur length.
Makes sense, for every increase in one additional centimeter, we can expect the height to be proportional to the slope.
3. The femur length for someone with an expected height of 2.5 centimeters.
Doesn't make sense, the linear relationship relies on the femur length to get the height.
4. The change in expected femur length for every one additional centimeter of height.
Doesn't make sense, again, the linear relationship relies on the femur length.
