Answer:

vvv ahah hopefully it helps

Step-by-step explanation:

11. pi is irrational number since you can't write it down as a non-infinite decimal

12. .5 is rational since its a terminating decimal

13. .3 repeating is rational b/c it's represented as a ratio of two integers

Brilliant_brown [7]

Answer:

r = $\frac{C}{2\pi }$

Step-by-step explanation:

We simply are rearranging C= 2πr in terms of <em>r</em>. We just divide 2π on both sides.

Basing your answer on the appearance of the figures below, identify whether the mathematical expression is true or false.

KatRina [158]

Answer:

The mathematical expression is false

Step-by-step explanation:

* Lets use the figure to answer the question

- There are four triangles in the figure

- Δ ROB and Δ PTA appear congruent because:

# The side RO appears equal the side PT

∴ RO ≅ PT

# The side OB appears equal the side TA

∴ OB ≅ TA

# The side RB appears equal the side PA

∴ RB ≅ PA ⇒ SSS

∴ Δ ROB ≅ Δ PTA

- Δ DEF and Δ YXW appear congruent because:

# The side DE appears equal the side YX

∴ DE ≅ YX

# The side EF appears equal the side XW

∴ EF ≅ XW

# The side DF appears equal the side YW

∴ DF ≅ YW

∴ Δ DEF ≅ Δ YXW ⇒ SSS

- Δ ROB and Δ DEF have different shapes and sizes

∵ Δ ROB not appear congruent to Δ DEF

∴ Δ ROB ≠ Δ DEF

∴ The mathematical expression is false

Determine if 3√10 /4 is in simplest form. if the expression is not in simplest form explain why? HELP PLEASE

emmasim [6.3K]

The notation in its current form isn't entirely clear.

Did you mean to write $\frac{3\sqrt{10}}{4}$ ? The 4 isn't in the square root.

If so, then the expression is in simplest form because we cannot simplify $\sqrt{10}$ any further (note how 10 doesn't have any perfect square factors other than 1).

Also, the 3/4 portion is fully reduced already.

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

Or,

Did you mean to write $3\sqrt{\frac{10}{4}}$ ? This time the 4 is inside the square root.

If so, then we can simplify like this

$3\sqrt{\frac{10}{4}}\\\\\frac{3\sqrt{10}}{\sqrt{4}}\\\\\frac{3\sqrt{10}}{2}\\\\$

This means that $3\sqrt{\frac{10}{4}}=\frac{3\sqrt{10}}{2}\\\\$
