can you please help me :)

Answer:

105.12 ft^2

Step-by-step explanation:

Area of rectangle = 8 × 10 = 80 ft^2

Area of semicircle = 1/2π × 4^2

4 is the radius of the semicircle.

Since we use 3.14 to approximate π...

Area of semicircle = 1/2× 3.14 × 4^2 = 25.12

∴Total area = 25.12 + 80 = 105.12 ft^2

Answer: 105.12ft²

Step-by-step explanation: first we need to find the area of the rectangle with the formula: length × width so, 8ft × 10ft = 80 ft².

Now we can find the area of the semicircle with the formula: πr²÷ 2 so, (3.14 × 4²) ÷ 2 = 25.12ft². Now we need to calculate the area of the whole shape and we can do this by adding together our rectangle and semicircle so, 80ft + 25.12ft = 105.12ft².

Answer:

5x - 2 = 3x = 14

8x -2 = 14

8x = 14 + 2

8x = 16

x = 2

Step-by-step explanation:

Answer:

add 5x and 3x then add -2 to 14. it should be 8x=12 then divide 8x and 12 by 8 and its 12/8 or simplify to 6/4 or 1 1/2 so combine like terms then addition then division i think :)

Step-by-step explanation:

Answer:

No, it's not a function.

Step-by-step explanation:

This is not a function because the x-inputs repeat. It would be a function if each x-input was a different number, but the inputs 3 and 4 repeat twice. Therefore, this is not a function.

Answer:

This is NOT a function because you CANNOT have same x values twice.

B

Step-by-step explanation:

since the formula requires you to subtract the x value, if the x value were to be negative(left) then the equation would be (x+3) because minus minus equals to plus but in this case it is (x-3) that means that the x value was positive.

Answer:

Step-by-step explanation:

Given that

the number of colors on the shirts(x), and

the total cost of the order(y).

since the number of colors is given as x

the total cost y can be represented as

y= 50x+ 75(3)

y= 50x+ 225

hence the total cost of 75 T-shirts is given by the model

Answer:

96 cm²

Step-by-step explanation:

The lateral surface area (A) is the sum of the areas of the 4 slant faces.

The faces are triangular with area [tex]\frac{1}{2}[/tex] bh , thus

A = 4 × [tex]\frac{1}{2}[/tex] × 8 × 6 = 2 × 48 = 96 cm²

Answer:

-32n-32=8n+48

-8             -8

 -40n-32=48

      +32   +32

-40=80

-40/-40=80/-40

n=-2

Step-by-step explanation:

You have to use pythagoras' theorem for this.

So AC is the length you want to find.

Pythagoras' theorem is a^2+b^2=c^2

In your triangle, AB=a, BC=b and AC=c

6^2+8^2=Ac^2

36+64= AC^2

100=AC^2

Square root both sides

10=AC

Therefore AC=10m

Step-by-step explanation:

Answer: 252

Step-by-step explanation:

The amount of tax paid by Sarah last month is £252.

The percentage is defined as representing any number with respect to 100. It is denoted by the sign %. The percentage stands for "out of 100." Imagine any measurement or object being divided into 100 equal bits.

Given that Sarah's gross income last month was £1260. She pays 20% tax on her gross income.

The tax amount is calculated by taking 20% of the gross income £1260.

Tax amount = 20% of £1260.

Tax amount = £1260 x 20 /100

Tax amount = £1260 / 5

Tax amount =£252.

Therefore, the amount of tax paid by Sarah last month is £252.
