Answer:

43cm

Step-by-step explanation:

Given

Length of Log = 291cm

First Piece = 67cm

Second Piece = 181cm

Required

Determine the length of the third piece

Given that the log was cut into three;

<em>this implies that;</em>

Length of Log = First Piece + Second Piece + Third Piece

Substitute values for first piece, second piece and length of log;

291 = 67 + 181 + Third\ Piece

291 = 248 + Third\ Piece

Subtract both sides by 248

291 - 248 = 248 - 248 + Third\ Piece

43 = Third\ Piece

Third\ Piece = 43

<em>Hence, the length of the third piece is 43cm</em>

3(x-2)+2(x+1)=-14<br> plz show work
Rom4ik [11]
Hello!

First, let's write the problem.
3\left(x-2\right)+2\left(x+1\right)=-14
Apply the distributive property on the left side of the equation.
=3x-6+2x+2
Add like terms.
=5x-4
Let's plug that in into the original equation.
5x-4=-14
Add 4 to both sides.
5x-4+4=-14+4
5x=-10
Divide both sides by 5.
\frac{5x}{5}=\frac{-10}{5}

Our final answer would be,
x=-2

You can feel free to let me know if you have any questions regarding this!
Thanks!

The base of a triangle is 8 1 3 meters and the height of the triangle is the fourth root of 16 meters meters. What is the area o
just olya [345]

Answer:

The area of triangle is 8 \frac{1}{3}\ m^{2}

Step-by-step explanation:

we know that

The area of a triangle is equal to

A=(1/2)bh

we have

b=8 1/3 m

convert to an improper fraction

8 1/3 m=(8*3+1)/3=25/3 m

The fourth root of 16 is equal to 2

\sqrt[4]{16}=(2^{4})^{1/4}=2

so

h=2 m

substitute

A=(1/2)(25/3)2=25/3\ m^{2}

convert to mixed number

25/3=(24/3)+(1/3)=8+1/3=8 \frac{1}{3}\ m^{2}

Complete the steps 4/9 divided by 1/2
DedPeter [7]

Answer: 0.88 (the 8 recurs)

Step-by-step explanation:

\frac{4}{9}÷\frac{1}{2}

\frac{4}{9}×\frac{2}{1}  (Then the the fraction should reciprocal so the values should shift to          the opposite side were 2 goes up and 1 goes down and the sign turns to the multiplication sign)

then u should multiply the two fractions which gives 8/9

next you should divide 8 by 9 which gives 0.88(the number eight is recurring which means that the number 8 keeps repeating no matter how many times you try to divide)
