Answer: Perimeter = 22*sqrt(2)
Area = 60.5 inches
Step-by-step explanation:
Simple a square has 4 equal sides.
It contains (by definition) 1 right angle but since we are not including and statement about parallel sides, it needs 4 right angles.
Answer:
4*[tex]\sqrt{60.5}[/tex] is peremiter and 60.5 is area
Step-by-step explanation:
11x11=121/2=60.5
[tex]\sqrt{60.5}[/tex]=one side of square
4*[tex]\sqrt{60.5}[/tex]=peremiter
60.5=area
Solve the inequality.
-1 <-4+ d
A d>3
B d>-3
C d<-3
D d<3
Answer:
A
Step-by-step explanation:
We add 4 on both sides
-1 + 4 < -4 + 4 + d

you are saving money for a new iPhone. You've already save $249 and you make nine dollars per hour at work. How many hours, (h), must you work to have enough money to buy a $699 iPhone? Which inequality models this situation?
Answer: about 78 hours if you round up the answer!
Step-by-step explanation:
Answer:
$249 + 9h > $699Step-by-step explanation:
We will start with $249 and then add the inequality for h. Note that the number can be larger than 699, but not lower.
$249 + 9h > $699FIND THE NUMBER OF SUBSETS FOR SET
A) CONTAINING 3 ELEMENTS
B) WHOSE CARDINAL NUMBER IS 5
Answer:
a) 8 subsets
b) 32 subsets
Step-by-step explanation:
The total number of subset of a set is known as the power of the set
Power of a set is expressed as;
P = 2^n
n is the number of element in the set
a) For a set containing 3 elements
n = 3
Power of the set = 2³
Power of the set is 8
This means that the set contains 8 different subsets
b) Cardinality of a set is the total number of element in the set
If the cardinal number of a set is 5, this means that the set contains 5elements
Hence the power of the set will be;
P = 2^5
P = 32
Hence the total number of subset for set whose cardinal number is 5 is 32
Find the length of each side of the triangle determined by the three points P1,P2,P 1,P 2, and P3. P3 State whether the triangle is an isosceles triangle, a right triangle, neither of these, or both. (An isosceles triangle is one in which at least two of the sides are of equal length.) P1=(−1,4);P2=(6,2);P3=(4,−5)P 1=(−1,4);P 2=(6,2);P 3 =(4,−5).
Answer:
IT IS BOTH
Step-by-step explanation:
Given the coordinate of the triangle, P1P2P3, we are to classify the triangle. To do that we need to know the length of each side of the triangle
P1P2, P2P3 and P1P2 using the formula for calculating distance between two coordinates
D = √(x2-x1)²+(y2-y1)²
For P1P2;
P1=(−1,4) P2=(6,2)
P1P2 = √(6-(-1))²+(2-4)²
P1P2 = √7²+2²
P1P2 = √53
For P1P3;
P1=(−1,4) P3=(4,-5)
P1P3 = √(4-(-1))²+(-5-4)²
P1P3 = √5²+9²
P1P3 = √25+81
P1P3 = √106
For P2P3;
P2=(6,2) P3 = (4,-5)
P2P3= √(4-6)²+(-5-2)²
P2P3 = √2²+7²
P2P3 = √53
Since two sides of the triangles are the same, this means that it is an isosceles triangle.
Let's check whether it is right angled by applying Pythagoras theorem
(√53)²+(√53)² = x²
x is the longest side (hypotenuse)
53+53 = x²
106 = x²
x = √106
Since the square of the hypotenuse is equal to the sum of the sum of the square of other two sides, then it is also a RIGHT ANGLED TRIANGLE

The sum of two numbers is 46. The difference of those numbers is 22. What are the two numbers?
Answer:
34 and 12
Step-by-step explanation:
so two numbers are x and x-22
then x+x-22=46
2x=68
x=34
x-22 = 12
The numbers are 34 and 12, which gives sum 46 and difference 22.
What is algebra?Algebra is a study of mathematical expressions, in which numbers and quantities are represented in formulas and equations by letters and other universal symbols.
Let the two numbers are a and b.
According to given conditions,
The sum of a and b is 46,
And the difference of a and b is 22.
Implies that,
a + b = 46 (1)
a - b = 22 (2)
Add equation (1) and (2),
2a = 68
a = 34
Substitute the value of a in equation 1 to get the value of b,
34 + b = 46
b = 46 - 34
b = 12
The required numbers are 34 and 12.

Explain why the expression below always has the same value, no matter what number other than zero you choose for p.
P-2P+3p-4P
---------------
P
Answer and explanation:
The expression P-2P+3P-4P cannot have the same values for different values of P. Let us illustrate this by substituting different values of P in the expression:
If P= 2
Substitute P=2 in the expression
2-2×2+3×2-4×2
=2-4+6-8
=-4
If P= 3
Substitute P=3 in the expression
3-2×3+3×3-4×3
=3-6+9-12
=-6
If P = 1
Substitute P=1 in the expression
1-2×1+3×1-4×1
= 1-2+3-4
= -2
If P = -2
Substitute P=1 in the expression
-2-2×-2+3×-2-4×-2
= -2+4-6+8
=4
Therefore we can see from the above that the expression has different values for different values of P

Ten less than half of a number(x) is 6.
Answer:
x = 32
Step-by-step explanation:
Given the following data;
Unknown number = x
Translating the word problem into an algebraic equation, we have;
[tex] \frac {x}{2} - 10 = 6[/tex]
Lowest common denominator (LCD) = 2
We multiply all through by 2;
[tex] 2* \frac {x}{2} - 2*10 = 2*6[/tex]
[tex] x - 20 = 12[/tex]
[tex] x = 12 + 20[/tex]
x = 32
Therefore, the unknown number is 32.
Write an equation of the line in point-slope form y-y_1=m(x-x_1) from the given point and slope.
(4,6); m=2
Answer:
The equation in point-slope form is [tex]y-6=2(x-4)[/tex].
Step-by-step explanation:
We are given the slope and a coordinate pair of a line.
Slope: 2Coordinate Pair (x, y): (4, 6)Therefore, we can now label our coordinate pair and substitute our values into the formula. Our formula is:
[tex]\displaystyle y-y_1=m(x-x_1)[/tex]
We can label our coordinate pairs with the [tex](x_1, y_1)[/tex] labeling method.
Therefore, since our two coordinates are:
x = 4y = 6We can label 4 as x₁ and 6 as y₁.
Then, we are able to determine m, or our slope.
m = 2Now, let's set up our equation.
[tex]\displaystyle y - y_1 = m(x - x_1)\\\\y - 6 = 2(x - 4)\\\\y - 6 = 2x - 8\\\\y = 2x - 2[/tex]
Therefore, our line is y = 2x - 2. However, the problem asks for it in point-slope form. So, this is exactly what we have in Step 2: y - 6 = 2(x - 4).

Write the solution set in interval notation.
First, you need to solve the inequalities.
[tex]4q\geq -16[/tex]
[tex]q\geq -4[/tex]
[tex]q+3<7[/tex]
[tex]q<4[/tex]
Now let's write the interval notation for the first one.
The lowest number for this would be -4. q cannot be less than negative -4. Since q can be -4 OR greater than, you use brackets. [-4,
q can be anything greater than -4. So the second number is infinity. Infinity uses parentheses because it is no exact number.
So the interval notation for the first inequality is [-4, ∞).
Now let's write the interval notation for the second one.
q can be anything less than 4. So the first number would be negative infinity: (-∞
q cannot pass 4, so the second number would be 4. Since q does not include 4, you use parentheses: 4)
The interval notation for the second inequality is (-∞, 4).
The interval notation for this compound inequality is [-4, ∞) or (-∞, 4).

On a sunny day, a 4-foot red kangaroo casts a shadow that is 5 feet long. The shadow of a nearby
eucalyptus tree is 20 feet long. Find the height of the tree?
Answer:
16 feet
Step-by-step explanation:
Set up a proportion where x is the height of the tree:
[tex]\frac{4}{5}[/tex] = [tex]\frac{x}{20}[/tex]
Cross multiply and solve for x:
5x = 80
x = 16
So, the tree is 16 feet tall
The value of a boat if depreciating at at a rate of 9% per year. In 2006 the boat was worth $17,800. Find the worth of the boat in 2013.
Answer:
The worth of boat in 2013 will be $9202.6
Step-by-step explanation:
Rate of depreciation = 9% = 0.09
Cost of Boat in 2006 =$ 17,800
Cost of Boat in 2013 = ?
Years = 2013-2006= 7 years
The formula used is: [tex]\mathbf{A=P(1+r)^{t}}[/tex]
Since the value of boat is depreciating the value of r will be r=-0.09
Here P = 17,800 , r=-0.09 and t = 7 years Finding A
[tex]A=P(1+r)^{t}\\A=17,800(1+(-0.09))^7\\A=17,800(0.91)^7\\A=17,800(0.517)\\A=9202.6[/tex]
So, the worth of boat in 2013 will be $9202.6

To celebrate the first day of spring, Lin is putting stickers on some of the 100 lockers along one side of her middle school's hallway. She puts a skateboard sticker on every 4th locker (starting with locker 4), and a kite sticker on every 5th locker (starting with locker 5). Name three lockers that will get both stickers. After Lin makes her way down the hall, will the 30th locker have no stickers, 1 sticker, or 2 stickers? Explain how you know.
Answer:
The 30th sticker will have a sticker. The sticker will be 1 sticker (Kite Sticker) which will be put on the locker by Lin. This is because, following the arithematic progression of the sticker placement:
Locker 5 = Kite sticker
locker 10 = Kite sticker
Locker 15 = Kite sticker
.
.
Locker 30 = Kite sticker
It could be seen that at locker 30, the sticker to be placed by Lin will be Kite sticker

Hello :) um Im just trying to learn this question- "Select the division equation that can be used to find the solution to the problem. 4/9 kilogram of baking soda costs $2. How much does 1 kilogram of baking soda cost?"
2 ÷ 4/9= ?
4/9 ÷ 2= ?
2 ÷ 1/9= ?
2 ÷ 2/9= ?
=========================================================
Explanation:
We're told that 4/9 kg of baking soda costs $2
We can form the equation
4/9 kg = 2 dollars
We want to know the cost of 1 kg of baking soda, so we'll need to divide both sides by 4/9 to turn the "4/9 kg" into "1 kg"
Therefore,
4/9 kg = 2 dollars
turns into
1 kg = (2 ÷ 4/9) dollars
We could simplify further, but your teacher has decided not to.
