2. Do 12 times 2=24
3. Divide 24 by 3
4. Your answer is 8 girls
Or you could do it this way
Steps:
1. You could have just multiplied the 2 by a 4 to get 8.12 boys divided by 3 boys is 4. That means you multiple the two by 4 to get the girls.

Using the distance formula, d = √(x2 - x1)2 + (y2 - y1)2, what is the distance between point (-5, -2) and point (8, -3) rounded
Dennis_Churaev [7]

Option D: 13 units is the distance between the two points

Explanation:

Given that the points are (-5,-2) and (8,-3)

We need to find the distance between the two points.

The distance between the two points can be determined using the distance formula,

d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

Let us substitute the points (-5,-2) and (8,-3) in the above formula, we get,

d=\sqrt{(8-(-5))^2+(-3-(-2))^2}

Simplifying the terms within the bracket, we have,

d=\sqrt{(8+5)^2+(-3+2)^2}

Adding the terms within the bracket, we get,

d=\sqrt{(13)^2+(-1)^2}

Squaring the terms, we have,

d=\sqrt{169+1}

Adding, we get,

d=\sqrt{170}

Simplifying, we have,

d=13.04

Rounding off to the nearest tenth, we get,

d=13.0 \ units

Hence, the distance between the two points is 13 units.

Therefore, Option D is the correct answer.

The diameter of a planet is about 25,660 mi. The diameter of the planet's moon is about 35% of the diameter of the planet. What
kotegsom [21]

Answer:

4%

Step-by-step explanation:

Volume of sphere

v = (4/3)πr^3

Volume moon/ volume planet

We don't actually need the numeric value of the radius

just the 35% ratio

Radius of moon = .35 radius of planet

Vm/ Vp = (4/3)π(.35r)^3 / (4/3)π(r)^3

Cancel like terms

Vm / Vp = .35^3

Vm / Vp = 0.042875

Expressed as a percentage

Vm / Vp = 4.2875%

Rounded

Vm / Vp = 4%
