Calculate the areas and perimeters of each shapes, start bu calculating any missing sides.
Answers
Answer:
Perimeter of A = 46cm
Area of A = 112cm^2
Perimeter of B = 61cm
Area of B = 118cm^2
Step-by-step explanation:
So there are two shapes. I divided one into 2 parts ( shape A ) . And the other into three ( shape B
Shape A:
PERIMETER = S + S +S +S + S + S + S + S ( THE SHAPE HAS 8 SIDES )
= 5 + 5 + 20 + 11 + 3 + 3 + 5 + 4 ( THIS INCLUDES THE MISSING SIDES )
= 46 CM
AREA- To find the area you divide the shape
Part 1 - 4* 3 = 12cm^2 Part 2 - 20 * 5 = 100cm^2
Final part ( add part a and b ) - 12 + 100 = 112cm^2
Shape B:
PERIMETER = S + S + S + S + S ..,........ (UNTIL YOU GET TO 12 SIDES PROVIDED THE SHAPE HAS 12 SIDES :) )
= 12 + 2 + 2 + 4 + 5 + 4 + 4 + 4 + 6 + 6 + 12 + 5
= 61 CM
AREA- To find the area you divide the shape
Part 1 - 12* 2 = 24cm^2 Part 2 - 4 * 3 = 12cm^2 Part 3 - 12 * 6 = 72 cm ^2
Final part ( add part a, b and c ) - 12 + 72 + 24 = 108cm^2

Pulling out like terms
4.1 Pull out like factors :

x • (x3 - 2x2 - 9x + 18)
Checking for a perfect cube :
4.2 x3 - 2x2 - 9x + 18 is not a perfect cube
Trying to factor by pulling out :
4.3 Factoring: x3 - 2x2 - 9x + 18
Thoughtfully split the expression at hand into groups, each group having two terms :
Group 1: -9x + 18
Group 2: x3 - 2x2
Pull out from each group separately :
Group 1: (x - 2) • (-9)
Group 2: (x - 2) • (x2)
-------------------
Add up the two groups :
(x - 2) • (x2 - 9)
Which is the desired factorization
Trying to factor as a Difference of Squares:
4.4 Factoring: x2 - 9
Theory : A difference of two perfect squares, A2 - B2 can be factored into (A+B) • (A-B)
Proof : (A+B) • (A-B) =
A2 - AB + BA - B2 =
A2 - AB + AB - B2 =
A2 - B2
Note : AB = BA is the commutative property of multiplication.
Note : - AB + AB equals zero and is therefore eliminated from the expression.
Check : 9 is the square of 3
Check : x2 is the square of x1
Factorization is : (x + 3) • (x - 3)
Final result :
x • (x + 3) • (x - 3) • (x - 2)

[tex] \dfrac{-7600}{3} [/tex]
Step-by-step explanation:
The plane is descending, so the change in height is a negative change.
rate of descent = (change in height)/time
rate of descent = (new height - old height)/time
rate of descent = (7400 ft - 15000 ft)/(3 min)
rate of descent = (-7600 ft)/(3 min)

The direct distance from a starting point to a finish line is 15 miles. Unfortunately, you can't take the direct route. If you travel 12 miles east, how many miles north must you travel to reach the finish line? 10 19 9
Answers
Answer:
9 miles
Step-by-step explanation:
From Pythagoras :
Opposite^2 = Hypotenus^2 - Adjacent^2
The direct route = 15 miles = hypotenus
x² = 15^2 - 12^2
x² = 225 - 144
x² = 81
x =. Sqrt(81)
x = 9
Hence, you must travel 9 miles north
Answer:
9 miles :)
Step-by-step explanation:
a^2 + 12^2 = 15^2
a^2 + 144 = 225
a^2 = 81
a = 9
how do i calculate the range? {mean, median, mode, range} pls help ASAP
Also, can you tell me in the comments how to delete an answer or remove it?
Answers
Answer:
The anwer is below.
Step-by-step explanation:
To calculate mean a.k.a average of something is when you add all of the numbers in the set and then multiply by the number of numbers there were.
an example : 4, 5,6,7 = 4+ 5 + 6 + 7 + 3 = 25 divided by 5 ( the number of numbers there were ) which is 5 so the mean is 5
To calculate the median you have to organize the set of numbers from least to greatest choose the middle number and that's the median, If there is an even number of numbers in the set then you add the two middle numbers and divide it by 2.
an example : 5,7, 8, 4 = 4, 5, 7 , 8 = the middle numbers = 5 + 7 = 12 divided by 2 = 6
To calculate the mode you have to see which numbers comes more often in the set of numbers, If there are two different numbers that come often even if one is higher include them in the mode.
An example - 5,6,6,6,6,7,7,7. The mode in this is 6 but 7 comes often to so if your teacher tells you to include more than one mode in these kinds of situation you include 7 or in general you don't have to
To calculate the range you choose the greatest and the lowest numbers and substract the highest to the lowest number in the set.
An example 5, 6, 7 , 9 , 8 = 9 ( the highest number in this set) - ( substraction) 5 ( the lowest number in this set) and 9 - 5 = 4 so the range is 4

The cylinder's radius is 2 inches and it’s height is 3 inches.Step-by-step explanation:
A diameter is two radiuses long, so the cylinder's radius is:

The volume of cylinder is: V = πR²×H
Therefore:
12π = π×2²×H

Brett has a 30 year fixed rate mortgage for $112500 with monthly payments of $603.92. The annual interest rate is 5% what is the total cost of the principal and interest for this not rounded to the nearest dollar
Answers
Answer:
a. Total cost of the principal = $217,411.20
b. Interest for the mortgage loan = $104,911.20
Step-by-step explanation:
Total cost of the principal = Monthly payment * Number of years * Number of months in a year = $603.92 * 30 * 12 = $217,411.20
Total cost of the principal of the loan includes the mortgage loan amount and the interest for the mortgage loan. Therefore, the interest for the mortgage loan can be calculated as follows:
Interest for the mortgage loan = Total cost of the principal - Mortgage loan amount = $217,411.20 - $112,500 = $104,911.20

Tickets to the school play are $10 for adults, $4 for students and $3 for senior citizens. There were 670 tickets sold for Thursday's show, worth $5615. If there were 65 tickets sold to senior citizens, how many tickets were sold to adults and how many were sold to students?
Answers
Answer:
500
105
Step-by-step explanation:
This question would be solved using a simultaneous equation
let
a = number of adults who bought the ticket
b = number of students who bought the ticket
c = number of senior citizens who bought the ticket
a + b + c = 670 eqn 1
10a + 4b + 3c = 5615 -- eqn 2
If 65 senior citizen bought the ticket, substitute for c in equation 1 and 2
a + b + 65 = 670
a + b = 670 - 65
a + b = 605 eqn 3
10a + 4b + 3(65) = 5615
10a +4b = 5420 eqn 4
multiply equation 3 by 10 to derive equation 5. Subtract eqn 4 from eqn 5
10a + 10b = 6050 eqn 5
-
10a + 4b = 5420 eqn 4
= 6b = 630
b = 105
Students who bought the ticket are 105
Substitute for b in eqn 3
a + 105 = 605
a = 500
Adults who bought the ticket are 500
