Find the circumference of a semicircle with diameter d cm​

Answers

Answer 1

Answer:

Circumference of the semi-circle is d(π/2 + 1)

Step-by-step explanation:

Circumference of a semicircle is πr + 2r

So, since r = d/2,

therefore, π*d/2 + 2*d/2 = πd/2 + d = d(π/2 + 1).

Answers

Answer:

11.90

Step-by-step explanation:

oh yes sorry I didn't see what you chose lol

Answer:

Yes

Step-by-step explanation:

Rounding two decimal points mean there will be two numbers behind the decimal and since 6 is more than 5 and influences the result of the 9 the answer would be 11.90. It could be 11.9 but having said there is two decimal places there should be a 0 hope this helps!!

HELP ASAPPPPP PLZZZZ Question in pic!!!!!

Answers

Step-by-step explanation:

Given

5y + 68 = 3y + 96 (vertically opposite angles) and

3x + 18 = 5x + 2 (vertically opposite angles)

Now solve for x.

[tex]3x + 18 = 5x + 2 \\ 3x + 18 - 5x = 2 \\ - 2x + 18 = 2 \\ - 2x = 2 - 18 \\ - 2x = - 16 \\ x = - 16 \div - 2 \\ = 8[/tex]

Now Solve for y.

[tex]5y + 68 = 3y + 96 \\ 5y + 68 - 3y = 96 \\ 2y + 68 = 96 \\ 2y = 96 - 68 \\ 2y = 28 \\ y = 14[/tex]

Answers

Answer: 23.53

Step-by-step explanation:

We have, 170% × x = 40

or,

170

100

× x = 40

Multiplying both sides by 100 and dividing both sides by 170,

we have x = 40 ×

100

170

x = 23.53

If you are using a calculator, simply enter 40×100÷170, which will give you the answer.

find the slope-intercept equation of the line that passes through (0,1) and has a slope of -2/3

Answers

Answer:

y = -2/3x + 1

Step-by-step explanation:

We already know the slope, so all we need to do is find the y-intercept. To find that, we need to plug the coordinates into the equation so far, which is,

y = -2/3x + b

1 = -2/3(0) + b

1 = 0 +b

1 = b

So the equation is y = -2/3x + 1
