First, find the circumference of the circle which for a diameter of 25, would be roughly 78.54 (according to goo gle) and the equation for circumference, C= πd
Then, add the 120, because of the rectangle in between the two half circles.
So my thought process was find the circumference, assuming that it was a full circle because it has two halves of a circle on either end. Then after that, you would add the two sides of the rectangle that contribute to the size of the perimeter
Please correct me if Needed and have a good day!

The population of a city is 40,000 and the annual growth rate is 1.6%. Write an equation to model the population y after x years.
Answers
Y=40,000(1.016)^x
Explanation:
years= x
Predicted population= y
Initial population= 40000
you can find the population y after x years with the help of this function
For example:
If we want to know the population after 5 years, put x=5 and find y
Y after 5 years= 40000(1.016)^5

Auntie Sammy buys a hand bag. There was a discount
of 20%.
If Auntie Sammy paid $245, what was the original price?
Answers
Answer:
Step-by-step explanation:
I think the original proce would be $265
1. Subtract the percentage discount from 100
100 - 20= 80
2. Multiply the final price($245) by 100
245 × 100= 24,500
3. Divide the answer in step 2 by the answer in Step 1
24,500 ÷ 80= $306.25
answer is $306.25
How to check to ensure your answer is correct:
1. Multiply the "answer" by the discount price divided by 100. This will give the discount percentage in dollars.
$306.25 × 0.2( which is 20÷100)= $61.25(discount in dollars)
2. Subtract the discount in dollars from the "answer"
$306.25 - $61.25= $245(final price is the same as in the problem so it is correct)
OR
1. Multiply the original price by the number you get from step 1 in your problem divided by 100
$306.25 × 0.8(80 from the very first step divided by 100)= $245(the final price is the same given in the question)

If the volume of a solid cone is 440cm3 and
its perpendicular height is 14cm. Determine
its base diameter to the nearest whole
number
O a. 5.5cm
b. 12cm
С. 6cm
d. 11cm
Answers
Answer:
11
Step-by-step explanation:
1/3 nr^2h = volume of a cone
1/3 x 22/7 x 14 x r^2 = 440
r^2 = 440 x 3 x 7/22 x 1/14
r^2 = 30
r = 30
r = 5
The base diameter to the nearest whole number is 11cm
The volume of a coneThe formula for calculating the volume of a cone is expressed as:
V =1/3πr²h
Given the folllowing parameters
V = 440cm^3
h = 14cm
Substitute the given parameters
440 = 1/3(22/7) * 14r²
440 = 44/3 * r²
10 = r²/3
r² = 30
r = 5.5cm
d = 11cm
Hence the base diameter to the nearest whole number is 11cm

(B) -1
(C) 2 1/2
(D) 3 1/2
(D)
Answers
Answer:
-1 is the correct answer
Step-by-step explanation:
Move that many points on the number line
The position of B on number line is at - 1.
What is Number line?Number line is a horizontal line where numbers are marked at equal intervals one after another form smaller to greater.
Given that;
Point A is shown on the the number line below.
And, Another point, B , is to be placed on the number line and will be 2 1/2 unit from point A.
Now,
Since, The position of Point A = 1 1/2
And, Another point, B , is to be placed on the number line and will be 2 1/2 unit from point A.
So, The point B = 1 1/2 + (-2 1/2)
= 3/2 - 5/2
= - 2/2
= - 1
Thus, The position of point B = - 1
