Answer:
x=7
Step-by-step explanation:
Start by distributing the 3:
(3)(x)+(3)(−2)=22-x
Now we have:
3x−6=−x+22
Add x to both sides:
3x−6+x=−x+22+x
Now we have:4x−6=22
Add 6 to both sides:
Add x to both sides.
3x−6+x=−x+22+x
4x−6+6=22+6
Now we have
4x=28
Divide both sides by 4
x=7
The sum of all the angles in a trapezoid/trapezium is 360°.
90° + 60° + 150° + 3x = 360°
300° + 3x = 360°
3x = 360° - 300°
3x = 60°
x = 60°/3
x = 20°
Hope this helps!
Answer:
The surface area of the triangular prism is approximately 401.582 square feet.
Step-by-step explanation:
The figure represents a triangular prism, the procedure for calculating the surface area of the entire figure consists in adding the areas of each face (3 rectangles and 2 triangles):
![A = 2\cdot \left[\frac{1}{2}\cdot (9\,ft)\cdot (4\,ft)\right] + (16\,ft)\cdot (4\,ft) + (9\,ft)\cdot (16\,ft) + (16\,ft)\cdot \sqrt{(9\,ft)^{2}+(4\,ft)^{2}}](https://tex.z-dn.net/?f=A%20%3D%202%5Ccdot%20%5Cleft%5B%5Cfrac%7B1%7D%7B2%7D%5Ccdot%20%289%5C%2Cft%29%5Ccdot%20%284%5C%2Cft%29%5Cright%5D%20%2B%20%2816%5C%2Cft%29%5Ccdot%20%284%5C%2Cft%29%20%2B%20%289%5C%2Cft%29%5Ccdot%20%2816%5C%2Cft%29%20%2B%20%2816%5C%2Cft%29%5Ccdot%20%5Csqrt%7B%289%5C%2Cft%29%5E%7B2%7D%2B%284%5C%2Cft%29%5E%7B2%7D%7D)

Answer:
17
Step-by-step explanation:
16,16,17,17,17,17,18,18,19
You first have to arrange the numbers if it's even, divide by two and if it's odd and the answer is always a whole number.
They are both (kilograms and centigrams) weights with the same dimension (mass), so they can be converted from one to the other.
<span>1 kilogram (kg) = 1000 grams and 1 gram (g) = 100 centigrams (cg)
So, </span><span>4.3 kg = 4.3 x 1000 = 4300 g = 4300 x 100 = 430000 = 43 x 10^4 cg.
So, the final answer is --> 430000 centigrams or 43 x 10^4 cg.
