What is perimeter also called?
Perimeter is the total length of all sides of a shape, also known as the circumference.
Perimeter is a measure of the distance around a two-dimensional shape. It is the sum of the lengths of all the sides of a shape. Perimeter is also known as the circumference. When calculating perimeter, you measure the length of each side of the shape and add them together. For example, the perimeter of a square with sides of 4 inches each would be 16 inches. Perimeter is an important concept in geometry, and it can be used to calculate area, the space within a shape or figure. It can also be used to calculate the distance between two points. Knowing the perimeter of a shape can help you solve many problems in math, design, and science.

4. The volume of a cylinder is 9.5 m cube, rounded to the nearest tenth of a cubic
meter. Which diagram shows the cylinder?
====================================================
Explanation:
You'll have to go through each answer choice one by one to check if those dimensions lead to to a volume of roughly 9.5 m^3
For choice A, we have a radius of 0.7/2 = 0.35 meters and a height of 6.2 meters. The volume of the cylinder is pi*r^2*h = 3.14*(0.35)^2*6.2 = 2.38483 which rounds to 2.4 cubic meters. We can rule out choice A because we want 9.5 as a result instead of 2.4
We follow the same steps for choices B through D. You should find that choice D is the answer because:
V = pi*r^2*h = 3.14*(1.4/2)^2*6.2 = 9.53932 which rounds to 9.5 m^3.
Note the 1.4/2 is dividing the diameter 1.4 in half to get the radius.
Complete the following function table for the linear equation y=4x-1
First we can find value of x and. When x=0 then y=-1 and x=1 then y= 3
What is linear equation explain?A linear equation is an algebraic equation of the form y=mx+b involving only a constant and a first-order (linear) term where m is the slope and b is the y-intercept.So the above given equation is called a "linear equation of two variables," where y and x are the variables.
How do you find the value of Y?Finding the y value is easy if you know the slope of the line and the x coordinate. Review the equation for the slope of a line. The equation for finding the slope is: m = [y1 - y2] / [x1 - x2]. If you know x, you can solve for y to find the y value for the slope of the line.
Now we have y= 4x-1
lets x=0 then y= -1
x=1 then y=3
x=2 then y=7
To find slope
y=mx+c
y= 4x-1
so by comparing we can find m=4
Then we can evaluate given equation y=4x-1

What will be the successor of the greatest 7-digit number and the predecessor of the smallest 8-digit number? Is there any relation between these two numbers? If yes, state the relation.
Answer:
The largest 7-digit number, is a 7 nine digits, this number is:
9,999,999
If we subtract one, we get a 7-digit number smaller than this one.
if we add one, we get an 8-digit number.
Then this one is the greatest 7-digit number.
The successor of this number, is equal to the number plus one:
9,999,999 + 1 = 10,000,000
The smallest 8-digit number is the first 8-digit number, and we know that this one is:
10,000,000
And the predecessor is equal to this number minus one:
10,000,000 - 1 = 9,999,999
So we can conclude that:
The successor of the greatest 7-digit is the smallest 8-digit number
The predecessor of the smallest 8-digit number is the greatest 7-digit number.
And we could interpolate this for any N-digit number, such that:
The successor of the greatest N-digit is the smallest (N + 1)-digit number
The predecessor of the smallest (N + 1)-digit number is the greatest N-digit number.

Which set of side lengths forms a right triangle?
Answer:
11-60-61
Step-by-step explanation:
For right triangle, leg^2+Another leg^2=hypotenuse^2
11^2+60^2=61^2
Answer:
11 inches, 60 inches, 61 inches
Step-by-step explanation:
This is a right triangle, so the Pythagorean Theorem applies.
The Pythagorean Theorem states that the legs of the triangle, 'a' and 'b'—squared—must equal the hypotenuse, squared.
**Hypotenuse: the longest side of a triangle.**
[tex]a^{2} + b^{2} = c^2[/tex]
This sounds a bit complicated, so allow me to explain this to you.
11 and 60: legs of the triangle.
61: hypotenuse
If I were to plug in the numbers into the formula, it would look like this:
[tex]11^2 + 60^2 = 61^2[/tex]
This is the same as:
[tex]11 * 11 + 60 * 60 = 61 * 61[/tex]
[tex]121 + 3600 = 3721[/tex]
If the legs of the triangle, 121 and 3600, have a sum of the hypotenuse, 3721, then these side lengths can form a right triangle.
The other answer choices, however, do not follow the Pythagorean Theorem.

=================================================
Work Shown:
Part A
The ruler diagram shows the building on paper is 6.5 cm wide. The right side of the building lines up with the midpoint marker between 6 and 7.
1 cm = 2 m
6.5*(1 cm) = 6.5*(2 m)
6.5 cm = 13 m is the width of the building in real life
Or you can solve it like this
(1 cm)/(2 m) = (6.5 cm)/(x meters)
1/2 = 6.5/x
1*x = 2*6.5
x = 13
------------------------
Part B
(1 cm)/(2 m) = (x cm)/(4.6 m)
1/2 = x/4.6
1*4.6 = 2*x
4.6 = 2x
x = 4.6/2
x = 2.3 centimeters is the height of the building in the drawing

Therefore, for x = 45 and y = 20, the quadrilateral is a parallelogram.
Define quadrilateral.In geometry a quadrilateral is a four-sided polygon, having four edges and four corners.
What is a polygon?A polygon is a closed polygonal chain made up of a limited number of straight-line segments and is a type of planar figure in geometry. A polygon is an area that is bordered by a bounding circuit, a bounding plane, or both.
We know opposite sides of a parallelogram are equal in length and parallel. Given opposite sides of a parallelogram are:
(4x - 35) and (3x + 10)
(y + 15) and (2y - 5)
Now, setting those opposite sides equal to each other:
4x - 35 = 3x + 10 = >x = 45
y + 15 = 2y - 5 => y = 20
Therefore, x = 45 and y = 20, the quadrilateral is a parallelogram.

A financial advisor has recommended two possible mutual funds for investment: Fund A and Fund B. The return that will be achieved by each of these depends on whether the economy is good, fair, or poor. A payoff table has been constructed to illustrate this situation:
STATE OF NATURE
INVESTMENT GOOD ECONOMY FAIR ECONOMY POOR ECONOMY
Fund A $10,000 $2,000 –$5,000
Fund B $6,000 $4,000 0
Probability 0. 2 0. 3 0. 5
Draw the decision tree to represent this situation.
Perform the necessary calculations to determine which of the two mutual funds is better. Which one should you choose to maximize the expected value?
Suppose there is a question about the return of Fund A in a good economy. It could be higher or lower than $10,000. What value for this would cause a person to be indifferent between Fund A and Fund B (i. E. , the EMVs would be the same)?
$21,500 this would be cause a person to be indifferent between Fund A and Fund B (i. E. , the EMVs would be the same)
EMV 1 = 0.2*10,000 + 0.3*2,000 + 0.5*-5,000 = $100EMV 2 = 0.2*6,000 + 0.3*4,000 + 0.5*-0 = $2,400.
Comparing both funds based on EMV calculations, Fund B shows a higher EMV. Therefore, to maximize expected value, we should invest in Fund B with an expected value of $2,400. First, his EMV for Fund A is not the same as Fund A's return being higher or lower in good economic conditions. Therefore, the EMC can also be higher or lower. But obviously the economy changes quickly sometimes. You don't always get the same return. So relying solely on returns is risky. Relying heavily on favorable economic conditions makes Fund A vulnerable to change and increases investor risk, so investors need to be more diversified. We can do the calculation:
Fund A return in good economy = Difference between A and B: EMV (Fund A) = EMV (Fund B) 0.2*X + 0.3(2,000) + 0.5(- 5,000) = 2 4,000.2X = 4,300X = $21,500.
Therefore, if the economy is good, Fund A's return should be $21,500 for there to be indifference between Fund A and the fund B.

PROBLEM SOLVING Your friend has two standard decks of 52 playing cards and asks you to randomly draw one card from each deck. What is the probability that you will draw two spades
Answer:
[tex]\frac{1}{16}[/tex]
Step-by-step explanation:
We will start by calculating the probability of drawing a spade from one deck, and then square it since we need to get the chance of getting two spades. We know there are 13 spades in a deck, out of 52 cards, giving us:
[tex]\frac{13}{52}[/tex]
Which can be simplified to :
[tex]\frac{1}{4}[/tex]
Then, we will square this fraction since we need two spades in a row:
[tex]\frac{1}{4} * \frac{1}{4} = \frac{1}{16}[/tex]
So the probability is [tex]\frac{1}{16}[/tex].
