Find the diagonal of a cube if its side equals 5. When applicable, simplify radicals and show all of your work.

Answers

Answer 1

Answer:

Answer:

7.0711

Step-by-step explanation:

The diagonal of a square of side of length a is a√2.

Here, the length of the square is given as: 5 units.

So, the length of the diagonal is 5√2 units.

But √2 = 1.4142.. (Approx.)

So, the length of the diagonal, d = 5 X 1.4142.

This is equal to 7. 0711.

So, the answer is 7.0711 units.

Judith drove h hours at a rate of 55 mi/h. She did not reach her goal of driving 385 miles for the day. How long did she drive? Write an inequality and then solve for h.

Answers

if she did not reach her goal then
miles she drove must be less than 385
or
miles she drove<385

so rate=55 miles per hour
so
miles driven=h times 55
subsitute
55 times h<385
divide both sides by 55
h<7
she drove less than 7 hours

inequality=55h<385
h<7

A number has 6 hundreds, 7 tens, and 34 ones. What is the number?

Answers

600+ 70 + 34
600 + 104
704

well 600 so thats there, now we have to add 70 and 34 which makes 104, so since "1" is the hundred we have to add 104 and 600 which gives you 704.
