Stella [2.4K]

Answer:

13.7 cm

Step-by-step explanation:

  1. there are 360° in a circle and in this image, we can see 90°+90°+66.4°=260.4
  2. since we know that 360°-260.4°=99.6°
  3. The angle measure of arc AD is 99.6°

Now that we covered that, we can use the arc length formula in order to find the length of arc AD.

  1. arc length = 2πr(Θ/360°)
  2. 2π(7.9)(99.6°/360°) = 13.7329
  3. rounded to the nearest tenth = 13.7

I need help with numbers 20,21,and22
julsineya [31]

Answer:

20) the answer is -43

21) the answer is 25

22)the answer is -5

Step-by-step explanation:

20) \frac{p(p+n^{2})}{6}

n=-7

p=-6

we have:

\frac{-6*(-6+(-7)^{2})}{6}\\\\\frac{-6*(-6+49)}{6}\\\\\frac{-6*(43)}{6}\\\\\frac{-258}{6} \\-43

21) mp-(p-(m-n))

m= -1     n=-6   p=-10

-1*-10-(-10-(-1-(-6)))

10-(-10-(5))

10-(-15)

10+15=25

22) m-\frac{m+m}{2} - n

m=1   n=5

1- \frac{1+1}{2} -5

1- 2/2 -5

1-1-5 =-5

Evaluate the expression (2x + y) +5 when x = 4, y = 10.
Maru [420]

Answer:

The answer is 23.

Step-by-step explanation:

Our equation here is (2x + y) + 5.

If x=4, and y=10, let's plug that in into our variables, and simplify!

[2(4) + (10)] + 5

= [8+10] + 5

=[18] +5

=23

FInd the solution for 4(x - 5)=2(x - 10) +2x
crimeas [40]
Hello!

You solve this like an algebraic equation

You first distribute the 4 and 2

4x - 20 = 2x - 20 + 2x

Combine like terms

4x - 20 = 4x - 20

subtract 4x from both sides

-20 = 0x - 20

Add 20 to both sides

0 = 0

This means that there are infinite solutions to the equation.

Hope this helps!
