Answer:
2500 kg/m³
Step-by-step explanation:
Density of a material is the ratio of mass and volume of that material.
The S.I unit for density is grams per centimeters cubed (g/cm³) or kilograms per meter cubed (kg/m³)
Given density as 2.5 g/cm³ , convert to kg/m³
Formula is;
1g/cm³ = 1000 kg/m³
2.5 g/cm³=? cross-multiply
=2.5×1000 = 2500 kg/m³

Hello,
11x + 7 + -3x - 3 = 11x - 3x + 7 - 3 = (11 - 3)x + 4 = 8x + 4
Answer:
Step-by-step explanation:
The circle is divided into 5 sections. The probability that the needle lands on a particular color is equally likely.
So,
![P(red) = \frac{1}{5}\\\\P(green) = \frac{1}{5}\\\\](https://tex.z-dn.net/?f=P%28red%29%20%3D%20%5Cfrac%7B1%7D%7B5%7D%5C%5C%5C%5CP%28green%29%20%3D%20%5Cfrac%7B1%7D%7B5%7D%5C%5C%5C%5C)
Probability of not blue = 1 - Probability of blue
![= 1 - P(blue)\\\\=1 - \frac{1}{5}\\\\= \frac{4}{5}](https://tex.z-dn.net/?f=%3D%201%20-%20P%28blue%29%5C%5C%5C%5C%3D1%20-%20%5Cfrac%7B1%7D%7B5%7D%5C%5C%5C%5C%3D%20%5Cfrac%7B4%7D%7B5%7D)
Answer:
-3x^6 -x^4 +2x^3 -8x +8
Step-by-step explanation:
Use the distributive property 4 times.
(-3x^3 + 2x - 4)×(x^3 + x - 2)
= -3x^3(x^3 +x -2) +2x(x^3 +x -2) -4(x^3 +x -2) . . . . once
= -3x^6 -3x^4 +6x^3 +2x^4 +2x^2 -4x -4x^3 -4x +8 . . . . 3 more times
= -3x^6 +x^4(-3+2) +x^3(6 -4) +2x^2 +x(-4 -4) +8 . . . . group like terms
= -3x^6 -x^4 +2x^3 -8x +8
