Answer:

20 square meters

Step-by-step explanation:

To do this continue the line of the top of the rectangle so you split the figure into a triangle and a rectangle. The dimensions of the rectangle would be 8 by 2, so 8 * 2 = 16. Next, the dimensions of the triangle would be (4 - 2) by (8 - 4) = 2 by 4. The area would then be 2 * 4 = 8/2 = 4.

All you have to do now is add those two areas together, 16 + 4 = 20 square meters.

Answer:

x = -8

Step-by-step explanation:

4x - (x - 4) = - 20

Distribute the minus sign

4x - x +4 = -20

Combine like terms

3x+4 = -20

Subtract 4 from each side

3x+4-4 = -20-4

3x = -24

Divide by 3

3x/3 = -24/3

x = -8

Circle the volume in cm^3 of a cylinder with the radius 5cm and height 8cm

Phantasy [73]

Answer:

<em>628 </em> $cm^{3}$

Step-by-step explanation:

Since the formula to find the volume of a cylinder is $\pi r^{2}$ h, we just need to fill things in.

Since the radius is 5 and the height is 8 and we know that pi=3.14, our new equation is:

3.14*5^2*8.

5*5=25. Now we simplify.

3.14 * 25 * 8

78.5 * 8

<em>628 </em> $cm^{3}$

Hope this helps!! <3 :)

A limited-edition poster increases in value each year with an initial value of $18. After 1 year and an increase of 15% per year

Volgvan

Answer:

The required equation is $y = 18(1.15)^x$ .

Step-by-step explanation:

Consider the provided information.

The Initial value of poster = $ 18

After 1 year amount of increase = $ 20.70

With the rate of 15% = 0.15

Let future value is y and the number of years be x.

$y = 18(1.15)^x$

Now verify this by substituting x=1 in above equation.

$y = 18(1.15)^1=20.7$

Which is true.

Hence, the required equation is $y = 18(1.15)^x$ .
