rectangular pyramid are shown in
the diagram. What is the volume
of the pyramid in cubic meters?
Answer:
8 cubic meters
Step-by-step explanation:
Formula for the volume of a rectangular pyramid:
[tex]V=\frac{lwh}{3}[/tex]
Take note
[tex]l=[/tex] base length
[tex]w=[/tex] base width
[tex]h=[/tex] pyramid height
We are given [tex]l[/tex], [tex]w[/tex], and [tex]h[/tex].
Lets solve for [tex]V[/tex]
[tex]l=3[/tex]
[tex]w=2[/tex]
[tex]h=4[/tex]
Now plug in our numbers into the formula:
[tex]V=\frac{3*2*4}{3}[/tex]
Evaluate the numerator
[tex]3*2*4=24[/tex]
Then we have
[tex]V=\frac{24}{3}[/tex]
Simplify and we get:
[tex]V=8[/tex]
Find the area of a circle with a diameter of 16.
Either enter an exact answer in terms of piπpi or use 3.14 for piπpi and enter your answer as a decimal.
Answer:
64π or 200.96
Step-by-step explanation:
The area of a circle is [tex]\pi r^2[/tex]. The radius of the circle is half the diameter, which is 16/2 = 8. The area of the circle is 64π.
Answer:
64π = area
200.96 = area
Step-by-step explanation:
Diameter = radius * 2
16 = 2r
radius = 8
Radius^2 * π = area
8^2 * π = area
64π = area
64*3.14 = area
200.96 = area

one side of a rectangle is 7 inches longer than another side. If the longer side of this rectangle decreases by 3 inches, and the shorter side increased by 2 inches, the area of the new rectangle equals the area of the original rectangle. Find the dimensions of the original rectangle.
Answer:
The length is 15 and the width is 8
Step-by-step explanation:
Use this formula to find what the dimensions are. x is the length of the shorter side while (x+7) is the length of the longer side:
(x+7)(x) = ((x+7)-3)(x+2)
x = 8
(8+7)(8) = ((8+7)-3)(8+2)
15(8) = (15-3)(10)
120 = 12(10)
120 = 120
The length is proved 15 and the width is proved 8.
What is the perimeter of a shape?
Perimeter is the combined ammount of all the sides added together.
For example, if a square has sides of 4, it would be 16 because 4+4+4+4 = 16 units.
Answer:
Perimeter is the total distance around the outside of a shape.
Step-by-step explanation:
A perimeter is a closed path that encompasses, surrounds, or outlines either a two dimensional shape or a one-dimensional length. The perimeter of a circle or an ellipse is called its circumference. Calculating the perimeter has several practical applications. A calculated perimeter is the length of fence required to surround a yard or garden. The perimeter of a wheel/circle (its circumference) describes how far it will roll in one revolution. Similarly, the amount of string wound around a spool is related to the spool's perimeter; if the length of the string was exact, it would equal the perimeter.

What is the slope of the line that passes through the points (7, -6) and (6, -6)? Write your answer in simplest form.
Undefined
Solution:Notice that the x-coordinates of the points that the line intersects are the same.If the x-coordinates are the same, then the slope is undefined.If the slope is undefined, then the line's run is equal to 0 units.Remember the slope formula: Rise/RunRise - how many units we move up or downRun - how many units we move left or rightIf the run is zero, then we basically divide by zero, which we can't do.Hope it helps.

In order to study the amounts owed to a particular city, a city clerk takes a random sample of 16
files from a cabinet containing a large number of delinquent accounts and finds the average amount
rowed to the city to be $230 with a sample standard deviation of $36. It has been claimed that the
true mean amount owed on accounts of this type is greater than $250. If it is appropriate to assume
that the amount owed is a Normally distributed random variable, the value of the test statistic
appropriate for testing the claim is
(a) -3. 33 (b) - 1. 96
(c) - 2. 22
(d) -0. 55
(e) - 2. 1314
Using the t-distribution, it is found that the value of the test statistic is given by:
(c) -2. 22
What are the hypotheses tested?At the null hypotheses, it is tested if the mean is not greater than 250, that is:
[tex]H_0: \mu \leq 250[/tex]
At the alternative hypotheses, it is tested if it is greater, that is:
[tex]H_1: \mu > 250[/tex]
What is the test statistic?It is given by:
[tex]t = \frac{\overline{x} - \mu}{\frac{s}{\sqrt{n}}}[/tex]
The parameters are:
[tex]\overline{x}[/tex] is the sample mean.[tex]\mu[/tex] is the value tested at the null hypothesis.s is the standard deviation of the sample.n is the sample size.In this problem, the values of the parameters are:
[tex]\overline{x} = 230, \mu = 250, s = 36, n = 16[/tex].
Hence, the test statistic is given by:
[tex]t = \frac{\overline{x} - \mu}{\frac{s}{\sqrt{n}}}[/tex]
[tex]t = \frac{230 - 250}{\frac{36}{\sqrt{16}}}[/tex]
t = -2.22.
Which means that option C is correct.

The number a is less than the number b by 1/5 of b. By what part of a is b greater than a?
Answer:
b is greater than a by 1/4 of a
Step-by-step explanation:
The statement “The number a is less than the number b by 1/5 of b”
means “if we subtract one fifth of b from b itself we get a”
we write this mathematically like this :
[tex]a=b-\frac{b}{5}[/tex]
_________
[tex]\rightarrow a = \frac{5b-b}{5} =\frac{4b}{5}[/tex]
[tex]a=\frac{4b}{5} \Longrightarrow 5a=4b[/tex]
[tex]5a=4b\Longrightarrow b=\frac{5a}{4}[/tex]
[tex]\Longrightarrow b=\frac{5a}{4} =\frac{4a+a}{4}=\frac{4a}{4}+\frac{a}{4}=a+\frac{a}{4}[/tex]

Camilo uses 32 ounces of filling to make empanadas de quest. He puts 0 empanadas on each of the 3 trays. write a fraction to show how many ounces of filling Camilo uses in each empanadas
The division is one of the four fundamental arithmetic operations. The filling that Camilo uses in each tray is 10.667 ounces.
What is Division?Division is one of the four fundamental arithmetic operations, which tells us how the numbers are combined to form a new one.
The total filling that was available with Camilo is 32 ounces, which he put in three different trays equally. Therefore, the filling available in each tray is equal to,
[tex]\rm \text{Filling in each tray} = \dfrac{\text{Total Filling}}{\text{Number of tray}}\\\\\text{Filling in each tray} = \dfrac{32\ ounces}{3} = 10.667 ounces[/tex]

Answer:
[tex]A_{total} = 217\ cm^2[/tex]
Step-by-step explanation:
Step 1: Determine the area of the bottom rectangle
[tex]A = l * w[/tex]
[tex]A = 14\ cm * 11\ cm[/tex]
[tex]A = 154\ cm^2[/tex]
Step 2: Determine the area of the top rectangle
[tex]A = l * w[/tex]
[tex]A = 7\ cm * (20\ cm - 11\ cm)[/tex]
[tex]A = 7\ cm * 9\ cm[/tex]
[tex]A = 63\ cm^2[/tex]
Step 3: Determine the total area
[tex]A_{total} = 154\ cm^2 + 63\ cm^2[/tex]
[tex]A_{total} = 217\ cm^2[/tex]
