If you take 2/5 minus 8/10 the final results would be -2/5 and it equals -0.4.

2/5 because 2/5 is 4/10. 8/10-4/10=4/10. 4/10=2/5 ~JZ

Calculate the area of this figure. Show all work and include proper units. Check photo for units

Allushta [10]

Answer:

92 ft²

Step-by-step explanation:

If you complete the square, you will add a right triangle with legs 10 - 6 = 4 ft.

The area of the figure is:

A = 10² - 1/2*4*4 = 100 - 8 = 92 ft²

Find the distance between the points (3, 8) and (0,4).

Bingel [31]

Answer:

Step-by-step explanation:

(3,8) (0,4)

X1 = 3 X2 = 0

Y1 = 8 Y2 = 4

$D=\sqrt{(X1-X2)^{2}+ (Y1-Y2)^{2} }$

$D= \sqrt{(3-0)^{2} + (8-4)^{2} }$

Do what's in the parentheses so...

3-0= 3
8-4= 4

Now plug it in!

$D= \sqrt{(3)^{2}+(4)^{2} }$

Now you are going to finish the parentheses so...

(3)^2= 9
(4)^2= 16

Plug that in so that you have this...

$\sqrt{9+16}$

Add 9+16 to get...

$\sqrt{25}$

Then you are going to find the number or numbers that make this a perfect square...

$\sqrt{25}= 5$

So 5 is your answer

A circular plate has a diameter of 11 inches. Which is closest tothe area of this plate? Show your work.A 17.3 square inchesC 95

monitta

Area of a circle= πr²

Data:
diameter=11 in

ratius=diameter/2=11 in/2=5.5 in

Area of this circular plate=π(5.5 in)²=30.25π in²=30.25 * 3.141592... in²≈
≈95.0 in².

answer : c 95.0 in²
