Jeremy is cutting a board into pieces that are 1 2/3 feet long . The board is 14 1/4 feet long . How many 1 2/3 -feet long piece

Solnce55 [7]

Answer:

Total number of 1 2/3 feet long pieces that will be cut=8 pieces

Step-by-step explanation:

This can be expressed as;

Total length of the board=length per piece×number of pieces

where;

Total length of board=14 1/4 feet

Length per piece=1 2/3 feet

Number of pieces=n

Replacing;

14 1/4=1 2/3×n

(57/4)=(5/3)n

n=(57/4)×(3/5)=8.55

Total number of 1 2/3 feet long pieces that will be cut=8 pieces

The gcf of two numbers less than or equal to 12 is 2. Their LCM is 20.What are the numbers?

bixtya [17]

We know:

$LCM(a,\ b)=\dfrac{ab}{GCF(a,\ b)}$

We have

$GCF(a,\ b)=2,\ LCM(a,\ b)=20,\ a\leq12,\ b\leq12$

Substitute:

$20=\dfrac{ab}{2}\qquad|\cdot2\\\\ab=40$

$40=1\cdot40=2\cdot20=4\cdot10=5\cdot8$

Only 4 and 10 meet the requirements of the question.

--------------------------------------------------------------------

40 and 1 NOT, because 40 > 12

20 and 2 NOT, because 20 > 12

5 and 8 NOT because GCF(5, 8) = 1

Consider the triangle.<br> 45°<br> 80°<br> Find the measure of the unknown third angle.

Elina [12.6K]

Answer:

$55 \degree$

Step-by-step explanation:

Let the unknown angle be x

As the interior angles in a triangle are added up to 180°

$x + 45 + 80 = 180 \\ x + 125 = 180 \\ x = 180 - 125 \\ x = 55 \degree$

Hope this helps you.

Let me know if you have any other questions:-)
