Three people are kayaking. They all started at the same point and rowed in the same direction for 20 minutes. Laura rowed 7/8 mile
Daniel rowed 1/2 mile
Annabelle rowed 1/4 mile
Part A:
Did Laura row a distance greater than, less than, or equal to the combined distance of Daniel and Annabelle?

Answers

Answer 1
Answer:

We can make everything have the same denominator so we can add, subtract, and compare them:

The common denominator between 2, 4, and 8, is 8.

7/8 = 7/8

1/2 = 4/8

1/4 = 2/8

The question is if Laura rowed more, less, or the same to the combined distance of Daniel and Annabelle:

Laura : 7/8

Daniel: 4/8

Annabelle: 2/8

4/8 + 2/8 = 6/8

So Daniel and Annabelle's distance combined is 6/8, which is less than Laura's:

7/8 > 6/8.

This means that Laura rowed more than Daniel and Annabelle.

How tall is a triangle that is 10ft x 10 ft x 10ft?

Answers

Are you saying that all 3 sides of the triangle are equal, and are 10-ft each ?

In that case, if you set the triangle down on one of its sides,
the vertex at the top will be 5√3 = about 8.66-ft above the table.
Square root of 75 or 8.66 rounded. Use Pythagorean Theorem.
