First, let's make it so that 6/8 and 4/5 have the same denominator.
Find the LCM: 40
8 ÷ 40 = 5
5 ÷ 40 = 8
Now that we have this info, let's convert the numerator to match the denominator.
4/5:
4 × 8 = 32
So... 4/5 = 32/40
6/8:
6 × 5 = 30
So... 6/8 = 30/40
Now let's add:
30/40 + 32/40
30 + 32 = 62
Therefore: 62/40
Now let's add those whole numbers: 5 + 4 = 9
Our answer: 9 62/40
Let's simplify: 10 22/40
Therefore, C is the correct answer.

Find the Area of the figure below, composed of a rectangle and a semicircle. Round to
the nearest tenths place.
14
10
Answer:
Submit Answer
Answer:
The area of given figure is: 179.3
Step-by-step explanation:
The figure consists of a rectangle and a semi-circle
The length of rectangle is 14 and width is 10.
The width of rectangle is also the diameter of the semi-circle.
So,
d = 10
[tex]r = \frac{d}{2} = \frac{10}{2} = 5[/tex]
Area of Semi-Circle:
[tex]C =\frac{ \pi r^2}{2}\\= \frac{3.14 * (5)^2}{2}\\=\frac{3.14*25}{2}\\=\frac{78.5}{2}\\= 39.25[/tex]
Area of Rectangle:
[tex]R = Length * Width\\R = 10*14\\R = 140[/tex]
The total area will be the sum of area of rectangle and the area of semi-circle
So,
[tex]Total\ Area = C + R\\= 39.25 + 140\\=179.25[/tex]
Rounding off to nearest tenth
The total area is: 179.3

vanishing point, how tall is it?
d.
160 cm
8 cm
C.
b. 0.1875 cm
a.
5.3 cm
Answer:
5.3cmStep-by-step explanation:
Step one:
given data
First tree
the tree is 8cm tall
and 30cm from the vanishing point
Third tree
let the tree be x cm tall
and 20cm from the vanishing point
Step two:
if 8cm tree will be 30cm at the vanishing point
then x cm tree will be 20cm at the vanishing point
cross multiply we have
x= (20*8)/30
x=160/30
x=5.3cm
The third tree is 5.3cm tall
A parent volunteer group is raising money by making custom hats to sell at
school activities. They plan to sell the hats for $12. Each hat costs $6 to
make. They spent $50 for advertising.
Use n to represent the number of hats they sell. Multiply this by the money
they make for each hat, then subtract the advertising cost.
Which expression represents the money that the group raises?
A. 12n - 6 - 50
O B. 50 - (12 – 6) n
O C. (12 - 6)n - 50
O D. 12 - 6n - 50
Answer:
B
Step-by-step explanation:
The answer is B because you minus 50 from 12 and 6.
Kaelyn is reading a book. The books thickness is 25 millimeters. How many of these books would fit on a shelf that is 1 meter long?
The number of books that can be fit on a shelf is 1 meter long and will be 40.
What is Algebra?Algebra is the study of mathematical symbols, and the rule is the manipulation of those symbols.
Kaelyn is reading a book.
The book's thickness is 25 millimeters.
Then the number of the books that can be fit on a shelf is 1 meter long will be
Let x be the number of the books.
The thickness of the book in meters will be 0.025 m.

The ratio of the number of people who own a Samsung Galaxy to the number of people
who own an iPhone is 3 : 5. If 1,000 more people own an iPhone than a Samsung
Galaxy, how many people own each type of phone?
Answer:
answer and explanation below

Consider the equation 5x + 7 = 2x + 28. Your tasks to explain the steps you would take, in
order, to solve the equation for x. Imagine that you are writing this for someone who is learning
about this process for the first time. You would be as specific as possible and write in complete
sentences.
Answer:
x=7
Step-by-step explanation:
Step 1: Put the variables and constants on the same side and change their signs so it'll look like this 5x-2x = 28 - 7, you always move the smaller number to either the left or right depending on its position in the problem.
Step 2: solve each side normally like this, 3x = 21
Step 3: to get x by itself divide 3 on both sides and you should get x=7
Here's a run through of the steps
5x+7=2x+28
-7 -7(subtract 7 from both sides
5x=2x+28-7
-2x -2x(subtract 2x from both sides)
5x-2x=28-7
3x=21
3x/3 = 21/3 (divide 3 from both sides)
x=7
