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.

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

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

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

Answer: 98268

Step-by-step explanation:

Given: In an international company,

Employees in one country = 22,700

If this is 23.1% of the total number of company's employees,

[[tex]1\%=\dfrac1{100}[/tex] , replace 'of' by '×']

i.e. 23.1% of (total employees) = 22700

[tex]\Rightarrow\ \dfrac{23.1}{100}\times\text{(total employees)}=22700\\\\\Rightarrow\ \text{Total employees}=\dfrac{22700\times100}{23.1}\\\\\Rightarrow\ \text{Total employees}=98268.4\approx98268[/tex]

Hence, there are 98268 employees in total.

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.

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

This is an example of direct variation.

So,      44    48            

           11       x

For this, you have to use the formula, 44x = 48 × 11

= (48 × 11) ÷ 44 = 12

Hence, your answer is 12 hours
