The digit 5 in which number represents a value of 0.5?

1 answer:

5 0

it's called 'tenths' and there's a thing that whatever goes on that side has no 'ones' it just starts with tens and it's ALWAYS followed by 'ths' after every digit

like hundredths or thousandths .

hope you understood it well

What is the perimeter of triangle ABC ?

blagie [28]

Answer:

$9+\sqrt{41}$

Step-by-step explanation:

From C-A, it goes from y=1 to y=5, so that 4 units

From A-B, it goes from x = -1 to x = 4, that is 5 units

Now, to find distance from B to C, we need to use the distance formula:

$D=\sqrt{(y_2-y_1)^2+(x_2-x_1)^2}$

Where the variables are the respective points of B and C,

B (4,5) & C(-1,1)

So x_1 =4, y_1=5, x_2=-1, y_2=1

Plugging into the formula we get:

$D=\sqrt{(y_2-y_1)^2+(x_2-x_1)^2}\\D=\sqrt{(1-5)^2+(-1-4)^2}\\D=\sqrt{16+25}\\ D=\sqrt{41}$

Summing it all (perimeter is sum of 3 sides):

Distance = $4+5+\sqrt{41}\\ =9+\sqrt{41}$

3rd answer choice is right.

Which of the following shows two congruent triangles

vaieri [72.5K]

Answer:

Step-by-step explanation:

but if u get the question wrong my next bet would be to go with only C because it has the marks on the sides if that makes sense

Solve for A if ñ=3.14 and r=3.

julsineya [31]

Answer:

28.26

Step-by-step explanation:

The question gives the first three digits of π, which is 3.14, and it gives us the radius, which is 3. So, just substitute them into the formula and you’ll get 3.14(3^2). Solve it and the final answer is 28.26.

Hope this helps! :)
