Answer:

everything except for C

Step-by-step explanation:

A - √2 is definitely over 1, so if you add a 4 to that, you'll get an answer over 5. (yes)

B - π is about 3.14, and since it's multiplied with 2, you'll obviously get a number greater than 5. in this case though, it'll be around 6.3. (yes)

C - √28 is a little greater than √25, so you can estimate using that. 15/5 is 3, and 5.2 - 3 is 2.2. (no)

D - √7 is around 2.7. if you divide 29 by that, you'll get an answer great than 10. (yes)

A) 4+√2 is roughly equal to 5.66

B) 2 pi is roughly equal to 6.28

C) 5.2 - 15/√28 is roughly equal to -74.17

D) 29/√7 is roughly equal to 10.96

So the answers would be A, B, and D.

What is the simplified form of 12x/900x²y4z6?

zalisa [80]

Answer:

$360xy^2|xz^3|$

Step-by-step explanation:

Given expression:

$12x \sqrt{900x^2y^4z^6}$

$\textsf{Apply radical rule} \quad \sqrt{ab}=\sqrt{a}\sqrt{b}:$

$\implies 12x \sqrt{900}\sqrt{x^2}\sqrt{y^4}\sqrt{z^6}$

Replace 900 with 30² :

$\implies 12x \sqrt{30^2}\sqrt{x^2}\sqrt{y^4}\sqrt{z^6}$

$\textsf{Apply radical rule} \quad \sqrt{a^2}=a, \quad a \geq 0:$

$\implies 12x \cdot 30|x|\sqrt{y^4}\sqrt{z^6}$

$\implies 360x|x|\sqrt{y^4}\sqrt{z^6}$

(We need to use the absolute value of √x² since the x term was originally to the power of 2, which means the value of x² is always positive since the exponent is even).

$\textsf{Apply exponent rule} \quad \sqrt{a^m}=a^{\frac{m}{2}}:$

$\implies 360x|x|\cdot y^{\frac{4}{2}}\cdot z^{\frac{6}{2}}$

Simplify:

$\implies 360xy^2|xz^3|$

(We need to use the absolute value of z³ since the z term was original to the power of 6, which means the value of z⁶ is always positive since the exponent is even).

Helen has 48 cubic inches of clay to make a solid square right pyramid with a base edge measuring 6 inches. Which is the slant h

Nikitich [7]

Answer: 5 inches

Step-by-step explanation:

Given: Volume of clay = 48 cubic inches

If we make a solid square right pyramid with a base edge a= 6 inches.

Then its base area = $a^2=6^2=36\ inches^2$
