Solve the equation by factoring.
c2 - 2c + 1 = 0
Answer:
The only solution is c=1
Step-by-step explanation:
c^2 - 2c + 1 = 0
What 2 numbers multiply to 1 and add to -2
-1 * -1 =1
-1 + -1 =-2
( c-1) (c-1)=0
Using the zero product property
c-1 =0 c-1 =0
c=1 c=1
The only solution is c=1

Image is a triangle with one side labeled as the 3 point 6 feet diameter of a semi-circle. The vertex opposite the semi-circle side is bi-sected by a horizontal line labeled 4 point 8 feet between the semi-circle diameter side and the opposing triangle.
Find the area of the irregular figure (use 3.14 for pi). Show your work. Round to the nearest tenth.
Answer:
13.7 ft²
Step-by-step explanation:
The figure is made up of two regular shapes.
1. A semi-circle of 3.6 ft
radius = 3.6/2 = 1.8 ft
Area = 1/2 × 3.14 × 1.8²
= 5.0868 ft²
2. A triangle
Area = 1/2 × base length × height
= 1/2 × 3.6 × 4.8
= 8.64 ft²
Area of the irregular shape = 5.0868 + 8.64
= 13.7268 ft²
To the nearest tenth = 13.7 ft²
The area of the irregular figure is 13.7 ft² to the nearest tenth.
What is the area of the triangle?The area of the triangle is defined as the product of half the base and the height of the triangle.
The area of the triangle = 1/2 x b x h
Given that vertex opposite the semi-circle side is bi-sected by a horizontal line labeled 4 point 8 feet between the semi-circle diameter side and the opposing triangle.
A semi-circle of 3.6 ft
The radius = 3.6/2 = 1.8 ft
Then Area = 1/2 × 3.14 × 1.8²
= 5.0868 ft²
Now triangle area is
Area = 1/2 × base length × height
= 1/2 × 3.6 × 4.8
= 8.64 ft²
Area of the irregular shape = 5.0868 + 8.64
= 13.7268 ft²
To the nearest tenth 13.7 ft²

Identify the model that shows 4 items being divided equally among 3 people. How much will each person have
Answer:
1 1/3 items
Step-by-step explanation:
Total number of items = 4 items
Total number of people = 3 people
4 items = 3 people
To know the number of items each person will get, we can write;
x items = 1 person
Divide both expressions
4/x = 3/1
3x = 4
x = 4/3
Express as mixed fraction;
4/3 = 1 1/3
Hence each person will receive 1 1/3 items

Answer:
Step-by-step explanation:
1.3-y/0.2=1.8
-y/0.2=0.5
y=-0.1
Answer:
y = -0.1
Step-by-step explanation:
1. subtract 1.3 from both sides 1.3 - y/0.2 - 1.3 = 1.8 - 1.3
2. simplify -y/0.2 = 0.5
3. multiply both sides by 0.2 0.2(-y/0.2) = 0.5 x 0.2
4. simplify -y = 0.1
5. divide both sides by -1 -y/-1 = 0.1/-1

What is the value of the square root of 72 to the nearest tenth?
Answer:
8.5
Step-by-step explanation:
Because I used a calculator
The square root of 72 is 8.48528137424 ...
The hundredths digit (8) rounds up.
So the square root of 72 rounded to the nearest tenth is 8.5.
Now you can multiply this to see if the product is near 72.
8.5 times 8.5 is 72.25.

Once upon a time, on an island in the middle of an ocean, several tribes lived and fought with each other. A time came when all the tribes agreed to everlasting peace. So, they decided to build a giant monument to celebrate this Peace Treaty. The monument required a certain number of logs, and the tribes had to agree on the number of logs that each tribe was to provide. Had there been two fewer tribes on the island, this number of logs would have been 6. Had there been one more tribe on the island, this number would have been 5. Unfortunately, the tribes could not agree on what number of logs would be fair for the actual number of tribes. So the tribes announced an eternal war - and were not heard from ever again. How many tribes were on the island?
Answer:
4 tribes. I don't even know how to do this question at all since it's way too difficult for me but this is an attempt.
Step-by-step explanation:
Let's use negative terms.
-2 = 6
-1 = 5
0 = 4
1 = 3
2 = 2
3 = 1
4 = 0

If 7x−6y=2 and −2x−y=3 are true equations, what would be the value of 5x−7y?
Answer:
-55
Step-by-step explanation:
7x-6y=2
-2x-y=3
by substitution method
y=3+2x
7x-6(3+2x)=2
7x-18-12x=2
-5x=20
x=-4
-2(-4)-y=3
8-y=3
-y=3-8
y=5
therefore the value of x=4 and that of y=5
5x-7y=5(-4)-7(5)
=-20-35
=-55
