Answer:
ok-
first thing to do is break the shapes into regular shapes that you already know how to figure the area of. so, #1 and #2 become an upright rectangle with a square attached to the bottom. #? is a rectangle with a semicircle at each end. #5 is a rectangle with a triangle up top... etc.
then, you figure the area of each part and add them all together.
let's look at #1:
right away, I see a square sticking off the right side that is 20x20- so that part is 400sq inches
then, I see the remainder as a rectangle that is 23x22.
23x22=506sq inches
then, add the 2 parts together.
506+400= 906sq inches total.
hope that helps!

If the value of y varies inversely with x , which function represents the relationship between x and y if y = 48 when x = 3?
A. Y= 144/x
B. Y= 16/x
C. Y= x/16
D. Y= x/144
Answer:
A. Y = 144/x
Step-by-step explanation:
Inversely means y = 1/x
If y = 48, when x = 3
so 144/3 = 48
Therefore the answer is A
If the value of y varies inversely with x then the function Y= 144/x represents the relationship between x and y if y = 48 when x = 3
What is a function?A relation is a function if it has only One y-value for each x-value.
If y varies inversely with x, it means that y is inversely proportional to x, or y=k/x, where k is a constant of proportionality.
To find k, we can use the given values of y and x:
y = k/x
48 = k/3
k = 144
Now that we know k, we can write the function that represents the relationship between x and y:
y = 144/x
Therefore, if the value of y varies inversely with x then the function Y= 144/x represents the relationship between x and y if y = 48 when x = 3

B)
131°
C)
135°
D)
139°
Answer:
B) 131°
Step-by-step explanation:
-4a + 139 = 4a + 123 because they are vertical angles
-4a + 139 = 4a + 123
reduce:
8a = 16
a = 2
4(2) + 123 = 131°

Suppose ABCD is a rhombus with AB = 12 inches. The midpoints of its sides are joined to form a quadrilateral. What type of quadrilateral is formed?
Answer:
A rectangle
Step-by-step explanation:
The given parameters are;
The quadrilateral ABCD is a rhombus;
The length of the sides of the rhombus = 12 inches
The lengths of the sides of a rhombus are equal
The opposite interior angles of the rhombus are equal
The length of each midpoint from the vertex = 12 in./2 = 6 in.
Therefore, we have;
The line joining the midpoints form a quadrilateral with the length of the opposite sides equal
The sum of the interior angles of the rhombus = 180°
From the diagram created with Microsoft Visio, we have;
4·a + 4·b + 360 = 4 × 180 = 360 + 360
4·a + 4·b = 360
a + b = 90°
We have;
The interior angles of the quadrilateral formed = x
a + b + x = 180° Sum of angles on a straight line
∴ x = 180° - (a + b) = 180° - 90° = 90°
x = 90°
Therefore, the interior angles of the quadrilateral formed = 90°
The quadrilateral formed having equal opposite sides, and all interior angle of 90° each is a rectangle
Timothy spent 1 hour 22 minutes less than Bill reading last week. Bill spent 47 minutes less than Pete. Pete spent 3 hours reading. How long did Timothy spend reading?
Answer: 51 minutes
Step-by-step explanation:
Firstly, Pete spent 3 hours reading. Bill spent 47 minutes less than Pete reading so Bill spent:
= 3 hours - 47 minutes
= 2 hours 13 minutes
If Bill spent 2 hours 13 minutes reading and Timothy spent 1 hour 22 minutes less than this, the amount of time that Timothy read for was:
= 2 hours 13 minutes - 1 hour 22 minutes
= 51 minutes

Answer:
Volume of the larger one = 476.5625
Step-by-step explanation:
Remark
This is a terrific little problem. Thanks for posting. I hope the answer is still useful to you. If the cylinders are similar it means that r and h are multiplied by a constant when moving from the smaller cylinder to the larger one. Everything else, believe it or not, remains the same.
Equations
Surface area of the smaller cylinder = 2pi*r^2 + 2pi*r*h
Surface area of the larger cylinder = 2*pi*(kr)^2 + 2pi*(kr)*(kh)
Surface area of the larger cylinder = k^2 (2*pi*r^2 + 2pi* r*h)
Solution
Surface area of the larger cylinder = k^2 (2pi*r^2 + 2pi*r*h)
============================= ==================
Surface area of the smaller cylinder (2pi*r^2 + 2pi*r*h)
surface area of the larger cylinder = k^2
surface are of the smaller cylinder = 1
200 / 128 = k^2 / 1 Divide the top and bottom of the left by 8
25 / 16 = k^2 Take the square roots of both sides
sqrt(25/16) = sqrt(k^2)
5/4 = k
Now work on the volume.
The volume of the larger cylinder = pi (kr)^2 (kh) = k^3 * pi * r^2 h
The volume of the smaller cylinder = pi * r^2 h
The volume of the larger cylinder to the smaller one = k^3 = 1.953125
x / 244 = 1.953125 Multiply both sides by 244
x = 1.953125 * 244
x = 476.5625

Is 7 to the 8th power times 7 equivalent to 7 to the the third power times 7 to third power equivalent?
Answer:
They are not equivalent.
Step-by-step explanation:
Before we solve the question, we need to know that from the laws of indices:
A^x x A^y = A^(x+y).
7 to the power of 8th power means 7^8
7^8 times 7 means 7^8 x 7. From the laws of indices we have 7^8 x 7 = 7^9.
7 to the power of 3rd power means 7^3
7^3 times 7 to the power of 3rd power means 7^3 x 7^3. From the laws of indices we have 7^3 x 7^3 = 7^6.
Obviously, 7^9 ≠ 7^3 therefore, they are not equivalent.
