A semi circle of diameter 6cm is cut from rectangle with sides 6cm and 8cm.
Calculate the perimeter of the shaded shape correct to 1 decimal place.
(My words) Add working steps if possible :)
Answers
First find the circumference of the semi-circle which is using the formula (2piR/2)
2*pi*3 / 2 = 3pi “R is radium which is half of the diameter” now we know that the circumference of the semi-circle is 3pi
Now the side at which lays the circle is opposite to 8cm side hence it will equal 8cm in total
So the side at which the semi-circle lays
= 3pi + 2cm remaining
(3pi)+2+6+6+8=31.42477796
Now round the answer to 1 d.p
Perimeter = 31.4cm

The table shows the transactions for one week for Tasha and Jamal Who was the greater account balance at the end of the week How Much greater?
______ has the greater balance at the end of the week. This balance is $_______ greater than the other balance
Answers
Answer:
Tasha has the greater balance at the end of the week.This balance is $381
The account balance is the remaining amount after the deduction of withdrawals from the deposits.
Tasha has the greater balance at the end of the week. This balance is $1 greater than the other balance.
What is account balance?It is the remaining amount after the deduction of withdrawals from the deposits.
We have,
Tasha:
Initial deposits = $250
Withdrawals = $20
Deposits = $65
Debit card purchases = $46
Balance = $250 - $20 + $65 - $46 = $249
Jamal:
Initial deposits = $200
Withdrawals = $60
Deposits = $135
Debit card purchases = $27
Balance = $200 - $60 + $135 - $27 = $248
We see that Tasha has a greater balance than Jamal and Tasha's balance is greater than Jamal's by $1.
Thus,
Tasha has the greater balance at the end of the week. This balance is $1 greater than the other balance.

Three people each rented a car with insurance and one more prson rented a car with a car wash. What is the expression for the total cost
Answers
Correct Question is:
A car company charges x dollars to rent a car plus extra options as shown in table.
Car seat = 50 $
Insurance = 75 $
Car Wash = 15 $
Three people each rented a car with insurance and one more person rented a car with a car wash. What is the expression for the total cost?
Step-by-step explanation:
3 people rented with insurance = (x + 75) * 3) = 3x +225
one person rented with car wash = (15+x)
Total car rental will be adding both equations = 3x +225 + 15 + x = 4x + 240

A small company has a fleet of 3 pickup trucks and 4 delivery vans. A larger company has the same ratio of pickup trucks to delivery vans. If the larger company has 45 pickup trucks, how many delivery vans does it have?
Answers
Answer:
60 delivery vans
Step-by-step explanation:
Smaller company:
Pickup truck : delivery van = 3 : 4
If the larger company has 45 pickup trucks
Let x = number of delivery vans
Larger company:
Pickup truck : delivery van = 45 : x
Equate both ratios
3 : 4 = 45 : x
3/4 = 45/x
Cross product
3 * x = 4 * 45
3x = 180
x = 180/3
x = 60
x = number of delivery vans = 60

Pythagoras lived over 2500 years ago. What is his theorem and why do we still use it today?
Answers
Answer:
The Pythagorean Theorem is helpful for two-dimensional navigation. You can use it along with two lengths to calculate the shortest path. The lengths north and west will be the triangle's two wings, and the diagonal will be the shortest line separating them. The same principles can be used for air navigation. He is best known in the modern day for the Pythagorean Theorem, a mathematical formula which states that the square of the hypotenuse of a right triangle is equal to the sum of the squares on the other two sides.
