Hey it's me again the life saver ;)

To find b we can use the linear pair property but since only 1 angle is given, we owuld need at least 2 angles on this situation to find b so, to do that we are first going to find a

a=>

53 + 47 + a = 180

a=180 - 100

a=80°

Now to find b=>

80 + 69 + b =180 (Because of Linear pair property)

b = 180-149

b=31°

Now that we have got b, to solve c, we can again use the sum of all angles in a triangle are 180°

c=>

31 + 85 + c =180

c=180 - 116

c=64

Hope it helps

Answer:

A=80

B=31

C=64

Step-by-step explanation:

A, 69, and b will equal 180 since it forms a straight line

A+69+b=180

to solve for A we subtract 53+47 from 180 and get 80

80+69+b=180

to get B we subtract 80+69 from 180 and get 31

to get c we add 85+b and subtract it from 180 getting c=64

Question: is 1 > 0.99999999...?<br>Prove algebraically.

Crazy boy [7]

No. We claim that $1=0.\overline{9}$ and use algebra to prove the statement.

Let $x=0.\overline{9}$ . Multiply this by ten to get $10x=9.\overline{9}$ . Subtract the initial equation to give $9x=9$ and divide by $9$ to see that $x=1$ . Substituting into the original equation gives $1=0.\overline{9}$ , proving the desired statement.

Use function notation that describes the value of the function m at x

mr_godi [17]

Answer:

A function is a relation in which each possible input value leads to exactly one output value. We say “the output is a function of the input.”

The input values make up the domain, and the output values make up the range.

Pythagorean theorem to determine if a triangle with sides 2 ft,5ft,4ft is a right triangle

Delvig [45]

$a^2 + b^2 = c^2$

$2^2 + 4^2 = 5^2$

$4 + 16 = 25$

$20 = 25$

Since 20 = 25 is clearly a false statement, the three side lengths 2 ft, 4 ft, and 5 ft do not form a right triangle.

a rectangular prism with a volume of 10 cubic units is filled with cubes with side lenghts of 1/2 unit how many 1/2 unit cubes d

Pachacha [2.7K]

Answer:

Step-by-step explanation:

The volume of a cube is

V=s^3, we are told the volume is 10u^3 and that it will be filled with cubes having a side of 1/2 so

n(1/2)^3=10, where n will be the number of these small cubes

n(1/8)=10 upon multiplying each side by 8

n=80

So it will take 80 cubes of side length 1/2 to have a volume equal to 10u^3
