Answer:
0.2%
Step-by-step explanation:
2,000 people tested the new shampoo.
4 people had a mild allergic reaction.
4 is what percentage of 2,000?
0.2 percent.
(2,000 = %99.8)
Answer:
x = 9
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
50° is an exterior angle of the triangle, thus
38 + 4x - 24 = 50 , that is
14 + 4x = 50 ( subtract 14 from both sides )
4x = 36 ( divide both sides by 4 )
x = 9
So for this trinomial, I will be factoring by grouping. Firstly, what two terms have a product of 16x^2 and a sum of 10x? That would be 8x and 2x. Replace 10x with 2x + 8x:
Next, factor x^2 + 2x and 8x + 16 separately. Make sure that they have the same quantity inside the parentheses: 
<u>Now you can rewrite this as 
, which is your final answer.</u>
Answer:
C
Step-by-step explanation:
y = (2x - 2) / 4 Interchange x and y
x = (2y - 2) / 4 Multiply both sides by 4
4x = 2y - 2 Add 2 to both sides.
4x + 2 = 2y Divide both sides by 2
4x/2 + 2/2 = 2y / 2
2x + 1 = y
Now put 3 in wherever you see an x
2*3 + 1 = y
6 + 1 = y
7 = y
Volume of the Triangular prism = 1/2 (base*height*length)
<span>V = 1/2 (2 * 2 * 5) </span>
<span>V = 10 cubic inches. </span>
<span>For the surface area, you can divide the prism into parts: </span>
<span>It's made of three rectangles and two equal triangles. </span>
<span>For the two triangles: </span>
<span>The area of each of the triangles is 1/2(base x height) </span>
<span>Area of each triangles = 1/2 (2 * 5) </span>
<span>Area of each triangles = 5 inches^2. </span>
<span>For the three rectangles: </span>
<span>* one is equal to base x length, </span>
<span>Rectangle1 = 2 x 5 </span>
<span>Rectangle1 = 10 inches^2. </span>
<span>* another is equal to side 1 x length </span>
<span>Rectangle2 = 3 x 5 </span>
<span>Rectangle2 = 15 inches^2 </span>
<span>* and the last is equal to side 2 x length. </span>
<span>Rectangle3 = 3 x 5 </span>
<span>Rectangle3 = 15 inches^2 </span>
<span>Adding all the components up, </span>
<span>10 + 15 + 15 + 5 + 5 = 50 inches^2 </span>
<span>Therefore, the surface area of the prism is greater than volume 50 > 10
hpe this helps:)</span>
