find the volume of the given pyramid. measurements are in feet.
answer:
v = 1/3 bh
the base (b) is a square and the area is20(20) = 400 ft^2
v = 1/3 400(26)
v = 1/3 (400) + 1/3(26) = 142 ft^2
IF the base area of the pyramid will be 400 square feet. Then the volume of the given pyramid will be 3466.67 cubic feet.
What is Geometry?It deals with the size of geometry, region, and density of the different forms both 2D and 3D.
The dimension of the pyramid is shown in the diagram.
Then the base area of the pyramid will be
Area = 20 x 20
Area = 400 square feet
Then the volume of the given pyramid will be
V = 1/3 x area x height
V = 1/3 x 400 x 26
V = 3466.67 cubic feet

Rob is travelling at a constant speed in a car. He travels 105km in 1 hour and 30 minutes. The speed limit is 80km/h. Is Rob travelling within the speed limit? Show how you decide.
Answer:
Yes.
Step-by-step explanation:
Let's first convert his speed to km/h.
[tex]\frac{105km}{1.5h} = 70\frac{km}{h}[/tex] > [tex]80\frac{km}{h}[/tex]. Therefore, Rob is traveling within the speed limit.

Answer:
Part A: 12.5 cm
Part B: 0.8 km
Step-by-step explanation:
Map scale problems can be solved with proportions.
Part A
5 cm / 2 km = x cm / 5 km
5/2 = x/5
2x = 25
x = 12.5
Answer: 12.5 cm
Part B
5 cm / 2 km = 2 cm / x km
5/2 = 2/x
5x = 4
x = 4/5
x = 0.8
Answer: 0.8 km

For a certain population of penguins, the distribution of weight is approximately normal with mean 15.1 kilograms (kg) and standard deviation 2.2 kg. Approximately what percent of the penguins from the population have a weight between 13.0 kg and 16.5 kg
Using the normal distribution, it is found that 56.78% of the penguins from the population have a weight between 13.0 kg and 16.5 kg.
Normal Probability DistributionThe z-score of a measure X of a normally distributed variable with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The z-score measures how many standard deviations the measure is above or below the mean. Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.In this problem, the mean and the standard deviation are given, respectively, by [tex]\mu = 15.1, \sigma = 2.2[/tex].
The proportion of penguins from the population have a weight between 13.0 kg and 16.5 kg is the p-value of Z when X = 16.5 subtracted by the p-value of Z when X = 13.
X = 16.5:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{16.5 - 15.1}{2.2}[/tex]
Z = 0.64
Z = 0.64 has a p-value of 0.7389.
X = 13:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{13 - 15.1}{2.2}[/tex]
Z = -0.95
Z = -0.95 has a p-value of 0.1711.
0.7389 - 0.1711 = 0.5678.
0.5678 = 56.78% of the penguins from the population have a weight between 13.0 kg and 16.5 kg.

The volume of the triangular prism is 1756.3 cubic yd option second is correct.
What is volume?It is defined as a three-dimensional space enclosed by an object or thing.
We know that the volume of a triangular prism is given by:
[tex]\rm V = \dfrac{1}{2}\times b\times l\times h[/tex]
Where b is the base length, l is the base width, and h is the height of the prism.
[tex]\rm h=\sqrt{13^2-(\dfrac{13}{2}) ^2[/tex]
h = 11.2583 yd
b = 13 yd
l = 24 yd
[tex]\rm V = \dfrac{1}{2}\times 13\times 24\times 11.2583[/tex]
V = 1756.29 ≈ 1756.3 cubic yd
Thus, the volume of the triangular prism is 1756.3 cubic yd option second is correct.

Kelly used the vertical line test to determine whether or not the curve that she
had been given is a function. After conducting the vertical line test, Kelly
determined that the curve is a function. Which of the following choices
represents the result of Kelly's vertical line test?
A. All vertical lines intersected the curve at exactly 2 points.
B. One vertical line intersected the curve at exactly 2 points.
C. One vertical line intersected the curve at exactly 1 point, while
another vertical line intersected the curve at exactly 2 points.
OD. All vertical lines intersected the curve at exactly 1 point.
All vertical lines intersected the curve at exactly 1 point.
===========================================================
Explanation:
If there is a case when a single vertical line crosses 2 or more points on the curve, then it will not be a function. In this situation, it is said that the curve fails the vertical line test.
Passing the vertical line test means that every vertical line passes through exactly one point on the curve. Each x input leads to exactly one output. If such a situation happens, then we have a function.
Since Kelly concluded that the curve is a function, this means the curve passed the vertical line test, and it points us to choice D as the answer.
Please help me find the area of compound shapes?!?!
Answer:
[tex]27cm^{2}[/tex]
Step-by-step explanation:
Area of compound shapes = Area of shape A + Area of shape B
Area of this shape = (L x B) + (L x B)
= (5 x 3) + (6 x 2)
= 15 + 12
= [tex]27cm^{2}[/tex]
Answer:
A = 27 cm²
Step-by-step explanation:
the figure consists of 2 rectangles

the one on the left with dimensions 5 cm by 3 cm
the total area (A) is then calculated as
A = (2 × 6) + (5 × 3) = 12 + 15 = 27 cm²
