Schach [20]

$\sqrt[3]{125x^{12}}=\sqrt[3]{125}\cdot\sqrt[3]{x^{4\cdot3}}=5\sqrt[3]{(x^4)^3}=5x^4\\\\\text{Answer:}\ B)\ 5x^4\\\\\text{Used:}\\\sqrt[n]{a\cdot b}=\sqrt[n]{a}\cdot\sqrt[n]{b}\\\\(a^n)^m=a^{n\cdot m}\\\\\sqrt[n]{a^n}=a$

Solve the equation 2(x-10)= 24 , what is the value of x

N76 [4]

Answer:

$x=22$

Step-by-step explanation:

$2(x-10)=24$

Distribute the parenthesis

$2x-20=24$

Add 20 to both sides

$2x=44$

Divide both sides by 2

$\frac{2x}{2} =\frac{44}{2}$

$x=22$

Hope this helps

Diane runs 10 miles in 55 minutes, how many minuets does she take per mile?

Brut [27]

Step-by-step explanation:

Hi!!

 It's simple, you can do it easily. 

no. of miles = 10 miles

time = 55 mins.

now,

no. of mins for 1 mile = no. of miles/ time

 = 10 /55

 =0.18181818 min.

so, she takes 0.181818 or 2/11 min per each mile.

Hope it helps...

A seagull has a vertical position a, and a shark has a vertical position b. Draw and label a point on the vertical axis to show

notsponge [240]

Answer:

Image attached

Step-by-step explanation:

The question asks to represent the position of two animals in a the cartesian coordinates plane. This is two perpendicular axis, the y-axis is the vertical one and the x-axis is the horizontal one. The animals are represented by dots, called a for the seagull and b for the shark.

Since the y-axis is the vertical axis and they ask to draw the points with a verical difference between them, we will draw the points in it.

Say the x-axis represents the sea surfice. The seagull would be over the sea, and the shark under the sea surfice (under x-axis).

This is the resulting drawing
